FIG. 4 is a diagram illustrating an example of a display screen of a liquid crystal monitor 24. It is a flowchart of the hand gesture operation process which the control part 23 performs. It is a figure explaining the modification of 1st Embodiment.

(First embodiment)
FIG. 1 is a block diagram showing the configuration of the imaging apparatus according to the first embodiment of the present invention. The imaging device 10 is a so-called compact type digital camera integrated with a lens. The imaging apparatus 10 includes an imaging optical system 21, an imaging element 22, a control unit 23, a liquid crystal monitor 24, a memory card 25, an operation unit 26, a DRAM 27, and a flash memory 28.

  The photographing optical system 21 is composed of a plurality of lenses, and forms a subject image on the imaging surface of the imaging element 22. The photographing optical system 21 is a so-called zoom lens having a variable focal length. The controller 23 can zoom up and down the photographing optical system 21 by driving an actuator (not shown). In FIG. 1, the photographing optical system 21 is illustrated as one lens.

  The image pickup device 22 is an image pickup device such as a CMOS or a CCD, for example, and picks up a subject image formed by the photographing optical system 21 and outputs an image pickup signal. The control unit 23 is an electronic circuit that controls each unit of the imaging apparatus 10 and includes a CPU and its peripheral circuits. A predetermined control program is written in advance in the flash memory 28 which is a nonvolatile storage medium. The control unit 23 controls each unit by reading and executing a control program from the flash memory 28. This control program uses the DRAM 27, which is a volatile storage medium, as a work area.

  The liquid crystal monitor 24 is a display device using a liquid crystal panel. The control unit 23 causes the image sensor 22 to repeatedly capture a subject image every predetermined cycle (for example, 1/60 second). Then, various image processes are performed on the imaging signal output from the imaging element 22 to create a so-called through image, which is displayed on the liquid crystal monitor 24. In addition to the above-described through image, for example, a setting screen for setting shooting parameters is displayed on the liquid crystal monitor 24.

  The control unit 23 performs various image processing on the imaging signal output from the imaging element 22 to create captured image data, and stores the image data in a memory card 25 that is a portable storage medium. The operation unit 26 has various operation members such as push buttons, and outputs an operation signal to the control unit 23 in response to the operation members being operated.

  The control unit 23 includes a hand detection unit 23a, a subject detection unit 23b, an operation frame setting unit 23c, a cursor arrangement unit 23d, and a function execution unit 23e in software form. Each of these units is realized by software by the control unit 23 executing a predetermined control program stored in the flash memory 28. Each of these units can be configured as an electronic circuit.

  The hand detection unit 23 a detects the position of the hand of a specific subject person from the subject image captured by the image sensor 22. The subject detection unit 23 b detects the position and size of a specific subject person from the subject image picked up by the image sensor 22. The operation frame setting unit 23c sets an operation frame described later around the subject person detected by the subject detection unit 23b. The cursor placement unit 23d places a cursor to be described later at a position in the shooting screen corresponding to the position of the hand in the operation frame. The function execution unit 23e executes a function corresponding to the icon in response to the cursor approaching one of a plurality of icons (detailed later) displayed on the liquid crystal monitor 24.

  FIG. 2 is a perspective view of the imaging apparatus 10. As shown in FIG. 2A, the housing of the imaging device 10 has a plate shape, and the liquid crystal monitor 24 is provided on the wide surface 40. Further, on another wide surface (not shown) facing the wide surface 40, a lens barrel (not shown) in which the photographing optical system 21 is built is provided. The subject is located in the direction indicated by the arrow x in FIG. 2A, that is, in the direction opposite to the display screen 51 of the liquid crystal monitor 24.

  In the following description, of the two wide surfaces of the housing of the imaging device 10, the wide surface 40 on which the liquid crystal monitor 24 is installed is referred to as the back surface, and the wide surface (not shown) on which the lens barrel is installed is referred to as the back surface. Called the front.

  The liquid crystal monitor 24 is configured to be rotatable by a shaft portion 42 provided at the upper part of the housing of the imaging device 10. In FIG. 2A, the liquid crystal monitor 24 is accommodated on the back surface of the imaging device 10. The user can turn the liquid crystal monitor 24 to the upper part of the imaging device 10 with the shaft portion 42 as a fulcrum.

  A state in which the liquid crystal monitor 24 is rotated to the maximum is shown in FIG. At this time, the display screen 51 of the liquid crystal monitor 24 faces the direction indicated by the arrow x in the drawing, that is, the same direction as the lens barrel. Therefore, when the imaging apparatus 10 is in the state shown in FIG. 2B, the person who is the subject can visually recognize the display screen 51. For example, when the imaging apparatus 10 performs a so-called live view display on the display screen 51, the person who is the subject can visually recognize his / her own image on the display screen 51.

  The housing of the imaging apparatus 10 is provided with a release button 43, a power button 44, and other buttons 45, 46, 47, 48, and 49 for performing various operations. These buttons are connected to the operation unit 26 described above, and the operation unit 26 outputs an operation signal to the control unit 23 in response to pressing of the button.

(Explanation of hand gesture operation)
When the liquid crystal monitor 24 faces the subject, that is, in the direction of the arrow x as illustrated in FIG. 2B, the control unit 23 sets the hand gesture operation mode for the imaging apparatus 10. When the hand gesture operation mode is set, a person who is a subject (a user who is a subject) can perform operations such as still image shooting and zoom operation by hand gestures (hand gesture). Note that even when the hand gesture operation mode is set, operations using the operation unit 26, such as taking a still image with a release switch, can be performed as usual.

  For example, when a photographer wants to take an image of himself / herself, the user takes the image pickup apparatus 10 with one hand and points the image pickup apparatus 10 toward himself / herself. At this time, it is difficult to operate an operation member provided on the back surface 40 of the imaging device 10 or the like. If the hand gesture operation mode is used, it is possible to perform shooting, zoom-in, or the like without operating an operation member provided on the housing.

  In addition, when the imaging device 10 is fixed with a tripod or the like, and shooting is performed away from the imaging device 10, shooting can be performed using a self-timer function or the like, but an operation such as shooting a movie or zooming in is performed. It is difficult. Even in such a case, if the hand gesture operation mode is used, it is possible to perform shooting, zoom-in, or the like without operating the operation member provided in the housing.

  When the hand gesture operation mode is set, the control unit 23 causes the image sensor 22 to repeatedly capture a subject image every predetermined cycle (for example, 1/60 second). Then, a through image is created from the imaging signal output from the imaging element 22 and displayed on the liquid crystal monitor 24. The hand detection unit 23a performs palm detection processing on the imaging signal that is the basis of the through image. Since the image pickup device 22 repeatedly outputs the image pickup signal at every predetermined cycle, the palm detection process by the hand detecting unit 23a is also repeatedly executed at every predetermined cycle. Note that the palm detection process may be performed on the through image, not on the imaging signal that is the basis of the through image. The execution period of the palm detection process may be longer than the imaging period. For example, the palm detection process may be performed only once for every two imaging operations.

  In the following description, it is assumed that the hand detection unit 23a detects only one palm at the same time. For example, when there are a plurality of palms, such as when a plurality of people are included in the shooting range, only one palm is detected from among them, and the control unit 23 will be described below with respect to that palm. Execute the process. For example, the palm with the highest priority may be determined based on the result of the face recognition and the preset priority for each person, or the palm that can be detected first in the shooting screen is as follows. It is good also as performing the process demonstrated by.

  A display screen 51 of the liquid crystal monitor 24 when the hand gesture operation mode is set is shown in FIG. When the hand gesture operation mode is set, the control unit 23 displays a through image on the entire surface of the display screen 51 and displays a plurality of icons 52a, 52b, 52c, 52d, 52e, and 52f superimposed on the through image. To do. These icons are user interfaces (UI) for performing hand gesture operations. The icons 52a, 52b, 52c, 52d, 52e, and 52f are symbols corresponding to, for example, a zoom-up function, a still image release function, a zoom-down function, and a video release function. Note that, when the hand gesture operation mode is set, the control unit 23 displays the through image on the liquid crystal monitor 24 by inverting the left-right image.

  When the subject person 54 points the palm toward the imaging apparatus 10, the hand detection unit 23a detects the palm. When the palm is detected by the hand detection unit 23a, the display screen 51 of the liquid crystal monitor 24 changes to the content shown in FIG. Specifically, in response to detection of a palm by the hand detection unit 23a, the control unit 23 displays a detection frame 56 indicating that the palm is detected around the palm. Next, the subject detection unit 23b detects the position and size of the subject person 54 having the palm. Thereafter, the operation frame setting unit 23 c sets the operation frame 55 around the detected subject person 54 and displays the operation frame 55 on the liquid crystal monitor 24.

  The operation frame 55 is a rectangular frame that defines the range in which the subject person 54 moves the palm. In the present embodiment, the operation frame 55 has a shape similar to the display screen 51. The cursor placement unit 23 d maps the palm position in the operation frame 55 to the position in the display screen 51. Then, the cursor 57 is arranged at the mapped position. For example, in the operation frame 55, if the palm is located at the upper left corner, the cursor 57 is arranged at the upper left corner of the display screen 51. Similarly, if the palm is positioned at the center of the operation frame 55 in the vertical and horizontal directions, the cursor 57 is arranged at the vertical and horizontal centers of the display screen 51.

  The user (subject person 54) visually recognizes the display screen 51 shown in FIG. 3, and the positions of the plurality of icons 52a, 52b, 52c, 52d, 52e, 52f on the display screen 51 and the detection frame on the operation frame 55. The position of 56 is grasped. Then, the palm (detection frame 56) is moved to a position in the operation frame 55 corresponding to the icon corresponding to the desired function. When the new position of the palm is detected by the hand detecting unit 23a, the cursor arranging unit 23d arranges the cursor 57 at a position in the display screen 51 corresponding to the new palm position. In other words, the cursor placement unit 23d moves the cursor 57 according to the movement of the palm. This is shown in FIG. When the cursor 57 on the display screen 51 overlaps any icon, the function execution unit 23e executes a function corresponding to the icon. For example, when the user places the cursor 57 on the icon 52b corresponding to “still image release”, the function execution unit 23e captures a still image.

  The reason for this is to enable each function to be executed by hand gesture even when the subject person 54 appears small on the shooting screen. The farther the subject person 54 is from the imaging apparatus 10, the smaller the size of the subject person 54 in the through image displayed on the shooting screen, that is, the display screen 51. Therefore, if the gesture operation mode is configured to execute each function by directly touching the palm with the icon, for example, the subject person 54 is captured with a size of the order shown in FIGS. In such a case, it is difficult to move the palm to the icon arranged at the end of the display screen 51. In the present embodiment, the gesture operation mode is implemented so that each function is executed by causing the icon to move the cursor 57 that moves in conjunction with the palm instead of directly touching the palm. Even when the person 54 is away from the imaging apparatus 10 to some extent, the function execution unit 23e can execute each function without moving the palm so much.

  Next, the operation frame 55 set by the operation frame setting unit 23c will be described in detail. The operation frame 55 has a shape similar to the display screen 51. From the size of the subject person 54 detected by the subject detection unit 23b, the range in which the palm of the subject person 54 detected by the hand detection unit 23a reaches is estimated. Then, the operation frame 55 is arranged around the base of the palm (for example, near the shoulder), that is, the center position of the movable range of the palm.

  In the present embodiment, since it is assumed that the gesture operation is performed with one hand, the operation frame setting unit 23c estimates a range within which the palm of the hand detected by the hand detection unit 23a reaches between the two hands of the subject person 54. Then, the size and position of the operation frame 55 are determined so as to be within the range. Note that the center of the operation frame 55 may be other than the vicinity of the palm base, for example, the center of the subject person 54.

  FIG. 4 is a flowchart of the hand gesture operation process executed by the control unit 23. The process shown in FIG. 4 is included in a control program that the control unit 23 reads from the flash memory 28 and executes.

  First, in step S100, the control unit 23 determines whether or not the liquid crystal monitor 24 is rotated and is in the state shown in FIG. The control unit 23 repeatedly executes the process of step S100 until the liquid crystal monitor 24 rotates to the position shown in FIG. If the liquid crystal monitor 24 is rotating, the control unit 23 advances the process to step S110.

  In step S110, the control unit 23 causes the image sensor 22 to capture a subject image. In step S120, the control unit 23 creates a through image based on the imaging signal output from the imaging element 22 by the imaging in step S110. In step S130, the control unit 23 displays the through image created in step S120 on the display screen 51 of the liquid crystal monitor 24, and displays the icons 52a, 52b, 52c, 52d, 52e, and 52f superimposed on the through image. . In step S140, the hand detection unit 23a attempts to detect the palm by performing known pattern matching or the like on the image signal output from the image sensor 22 by the image capturing in step S110. In step S150, the control unit 23 determines whether or not a palm is detected from the imaging signal in step S140. If no palm is detected, the control unit 23 advances the process to step S110. On the other hand, when the palm is detected, the control unit 23 advances the process to step S160.

  In step S160, the subject detection unit 23b detects the position and size of the subject person 54 having the palm detected in step S140. In step S163, the operation frame setting unit 23c covers at least the range including the palm detected by the hand detection unit 23a around the subject person 54 based on the position and size of the subject person 54 detected in step S160. An operation frame 55 is set. Thereafter, the set operation frame 55 is displayed on the display screen 51 so as to be superimposed on the through image.

  In step S166, the cursor placement unit 23d places the cursor 57 at a position in the live view (in the display screen 51) corresponding to the palm position in the operation frame 55 set in step S163. Thereafter, the arranged cursor 57 is displayed on the display screen 51 so as to be superimposed on the through image.

  In step S <b> 170, the control unit 23 causes the image sensor 22 to capture a subject image. In step S180, the control unit 23 creates a through image based on the imaging signal output from the imaging element 22 by imaging in step S170. In step S190, the control unit 23 displays the through image created in step S180 on the display screen 51 of the liquid crystal monitor 24, and displays icons 52a, 52b, 52c, 52d, 52e, and 52f superimposed on the through image. To do. At this time, the operation frame 55, the detection frame 56, and the cursor 57 are also displayed superimposed on the through image.

  In step S200, the hand detection unit 23a attempts to detect the palm by performing known pattern matching or the like on the image signal output from the image sensor 22 by the image capturing in step S170. In step S210, the control unit 23 determines whether a palm is detected from the imaging signal in step S200. If no palm is detected, the control unit 23 advances the process to step S110. On the other hand, when the palm is detected, the control unit 23 advances the process to step S220.

  In step S220, the cursor placement unit 23d places the cursor 57 at a position in the live view (in the display screen 51) corresponding to the position of the palm in the operation frame 55. In step S230, the function execution unit 23e determines whether the cursor 57 arranged in step S220 has overlapped with any of the icons 52a, 52b, 52c, 52d, 52e, and 52f. If the cursor 57 does not overlap, the function execution unit 23e advances the process to step S170. On the other hand, when the cursor 57 overlaps any of the icons, the function execution unit 23e advances the process to step S240. In step S240, the function execution unit 23e executes a function corresponding to the icon overlapped with the cursor 57.

According to the imaging apparatus according to the first embodiment described above, the following operational effects can be obtained.
(1) The operation frame setting unit 23c sets an operation frame 55 that covers at least the range including the palm detected by the hand detection unit 23a around the subject person 54 detected by the subject detection unit 23b. The cursor placement unit 23d places the cursor 57 at a position in the through image corresponding to the position of the palm in the operation frame 55. Then, the function execution unit 23e executes a function corresponding to the icon 57 when the cursor 57 comes close to any of the plurality of icons 52a, 52b, 52c, 52d, 52e, and 52f. According to the imaging device 10 having the above configuration, the operability is not deteriorated even when the user moves away from the screen.

(2) The operation frame setting unit 23 c sets an operation frame 55 having a shape similar to the shape of the display screen 51 of the liquid crystal monitor 24. Since it did in this way, the user can grasp | ascertain easily the position of the cursor 57 in the display screen 51, and the position of the palm in the operation frame 55. FIG.

(3) The operation frame setting unit 23c sets the operation frame 55 having a size corresponding to the size of the subject person 54 detected by the subject detection unit 23b. As described above, it is possible to provide a gesture operation function that does not change the feeling of operation regardless of the size of the subject person 54 in the through image.

(4) The operation frame setting unit 23c sets the operation frame 55 that falls within the reach of the subject person 54. Since it did in this way, even if the icon is arrange | positioned in which position of the display screen 51, the user can select the icon corresponding to a desired function only by a hand gesture, without moving from a present position.

(5) The operation frame setting unit 23c sets the operation frame 55 that falls within the range where one hand of the subject person 54 can reach, centering on the vicinity of the base of the one hand. Since it did in this way, the user can select arbitrary icons only by a hand gesture, without moving from the present position.

  The following modifications are also within the scope of the present invention, and one or a plurality of modifications can be combined with the above-described embodiment.

(Modification 1)
The operation frame setting unit 23c may change the size of the operation frame 55 in real time in response to the change in the size of the subject person 54 detected by the subject detection unit 23b. For example, when the subject person 54 moves back and forth and right and left with the palm facing the imaging device 10, the position and size of the subject person 54 on the shooting screen changes. When the operation frame setting unit 23c is configured so that the operation frame 55 follows the movement of the subject person 54, the operability of the imaging apparatus 10 is further improved.

(Modification 2)
In the above-described embodiment, it is assumed that the subject person 54 performs a gesture operation with one hand in the gesture operation mode. The present invention is not limited to such an embodiment, and the subject person 54 may perform a gesture operation with both hands. In this case, it is desirable that the operation frame setting unit 23 c sets the operation frame 55 that falls within the range where both hands of the subject person 54 can reach, with the center of both hands of the subject person 54 as the center. Alternatively, the hand detection unit 23a may detect both hands at the same time, or the cursor placement unit 23d may place two cursors 57 corresponding to both hands.

(Modification 3)
When the subject person 54 is located at the end of the shooting screen, the operation frame 55 may not fit on the shooting screen (through image). In such a case, the operation frame setting unit 23c may adjust the position or size of the operation frame 55 so that the operation frame 55 fits on the shooting screen. For example, the operation frame 55 may be placed in the shooting screen by shifting the center of the operation frame 55 in the direction opposite to the screen edge. Further, by reducing the size of the operation frame 55, the operation frame 55 may be stored in the shooting screen. It is also possible to combine both of them.

(Modification 4)
Instead of the function execution unit 23e executing the function corresponding to the icon as soon as the cursor 57 overlaps the icon, a step may be provided in which the user can confirm that the function corresponding to the icon is executed. For example, when the cursor 57 overlaps any of the plurality of icons 52a, 52b, 52c, 52d, 52e, and 52f, a function corresponding to the icon is displayed on the display screen 51 to notify the subject person 54. A notification unit is provided.

  FIG. 5 shows an example of a notification method by the notification unit. In response to the cursor 57 overlapping the icon 52b, the notification unit displays a character string 60 representing the function of the icon 52b on the display screen 51 of the liquid crystal monitor 24, and the function of the icon 52b is displayed to the user (subject person 54). Inform. In the function execution unit 23e, a predetermined determination operation is performed by the subject person 54 after the cursor 57 overlaps any of the plurality of icons 52a, 52b, 52c, 52d, 52e, and 52f and the notification unit performs notification. Accordingly, the function corresponding to the icon is executed. As the determination operation, for example, an operation of maintaining the state where the cursor 57 and its icon overlap each other for a certain time (for example, 3 seconds) or an operation of grasping the palm (making a fist) can be considered.

  In addition, the alerting | reporting method by an alerting | reporting part may not be limited to the display of the character string 60 on the display screen 51 illustrated in FIG. For example, the subject person 54 may be notified by reproducing a sound that reads out the function of the icon. In addition, when the cursor 57 overlaps any of the plurality of icons 52a, 52b, 52c, 52d, 52e, and 52f, the function does not correspond to the icon but the icon overlaps the cursor 57. You may make it alert | report. For example, by changing the color or shape of the icon on which the cursor 57 overlaps, it may be notified that the icon overlaps with the cursor 57.

(Modification 5)
In the embodiment described above, the trigger for the function execution unit 23e to execute various functions is that the cursor 57 overlaps one of the icons 52a, 52b, 52c, 52d, 52e, and 52f. This is an example of the trigger, and the function execution unit 23e only needs to be configured to execute a function when the cursor 57 comes close to the icon, and the cursor 57 is not necessarily the icon 52a, 52b, 52c, 52d, 52e, It does not have to overlap with 52f. For example, the function may be executed in response to the cursor 57 moving toward the icon for a certain distance, or the function may be executed when the rectangle circumscribing the icon and the cursor 57 overlap.

(Modification 6)
The hand detection unit 23 a detects the position of the hand of the subject person 54 by detecting the palm from the subject image captured by the image sensor 22. The hand detection unit 23a may detect the position of the hand of the subject person 54 by detecting something other than the palm. For example, the position of the hand of the subject person 54 may be detected by detecting fingers and wrists by pattern matching. Further, it may be possible to detect a hand wearing a glove or the like. Even if the hand detection unit 23a is configured as described above, if the hand of the subject person 54 can detect that the icon 52a, 52b, 52c, 52d, 52e, 52f is close, the present The invention can be applied.

  Furthermore, the present invention is not limited to hand gestures. If a predetermined gesture (gesture) performed by the subject is detected in the same manner as the above-described hand gesture (hand gesture), it is possible to realize the operation of the imaging apparatus using a part other than the hand.

(Modification 7)
When it is difficult for the subject person 54 to visually recognize the display screen 51 of the liquid crystal monitor 24 and the subject person 54 is too far from the imaging apparatus 10, the control unit 23 may invalidate the gesture operation mode.

(Modification 8)
In the above-described embodiment, the example in which the gesture operation is performed using the liquid crystal monitor 24 built in the imaging apparatus 10 has been described. However, the present invention is not limited to such an embodiment, and is connected to the outside of the imaging apparatus 10. Various controls related to the gesture operation mode may be performed using the display device. In this way, the size of the display screen 51 of the display device can be made larger than the housing of the imaging device 10, and the visibility of the display screen 51 is improved.

(Modification 9)
Any number of icons may be provided in the screen. The arrangement can be arbitrarily determined, and may be arranged at a place other than the end of the display screen 51 as in the above-described embodiments. Further, the position where the icon is arranged may be changed according to whether the palm detected by the hand detection unit 23a is the right hand or the left hand. For example, the operability of the imaging apparatus 10 is improved by arranging an icon on the right side of the display screen 51 when the right hand is detected and arranging the icon on the left side of the display screen 51 when the left hand is detected. To do.

  Further, the function assigned to each icon may be different from that exemplified in each of the above-described embodiments, as long as it is a function that can be executed by the function execution unit 23e (for example, playback mode setting, on / off of the auxiliary light emitting device, etc.). Any thing is acceptable. A user may be allowed to assign an arbitrary function to each icon. Furthermore, symbols other than icons (for example, character strings or pictures representing functions) may be used.

(Modification 10)
In the above description, the embodiment in which the present invention is applied to a lens-integrated digital camera has been described. However, the present invention is not limited to such an embodiment. For example, a so-called single-lens reflex digital camera capable of exchanging lenses is used.
