It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

The present invention proposes this solution for cameras in the prior art that do not quickly enter the shooting mode, especially cameras that are suitable for smart phones or tablet computers. The solution of the present invention focuses on the action of the user using the smart phone or tablet computer to shoot the object, that is, the action of first holding the smart phone or tablet computer, and then turning the phone or tablet computer sideways to aim at the shooting object. Corresponding components are set in the camera to detect whether there is a corresponding action, so as to determine whether the user needs to take a quick shot. According to the technical solution of the present invention, the problem that the user quickly enters the shooting mode is solved, and the smart phone and the tablet computer are slightly changed, and fully adapt to the user's usage habits.

It should be known that shooting in this article includes photography or photography, and it is realized by sharing the same shooting unit, and the user only needs to perform preset settings in the camera. In this way, after the camera is quickly started, it enters into corresponding photography or photography.

Example 1:

1 is a block diagram of a camera that quickly enters a shooting mode according to an embodiment of the present invention. As shown in FIG. 1 , the camera includes the following components: a hand-held sensor unit, an acceleration sensor, a controller, and a shooting unit. in:

The grip sensor is conductively connected with the controller, and is used to judge whether the camera is held in hand, specifically, whether the user's hand touches the effective touch area of the frame of the camera. In this way, the handhold sensor unit can give a signal that the user is handholding the camera.

The acceleration sensor is conductively connected with the controller, and is used to judge whether the camera has a horizontal screen movement. It should be known that the acceleration sensor includes a gyroscope and a three-axis acceleration sensor. Wherein, the acceleration sensor is preferably a three-axis acceleration sensor, and by measuring changes in the X, Y, and Z axes, it is judged whether the camera has a horizontal screen movement.

The controller starts the shooting unit to enter the shooting mode according to the determined signals transmitted by the hand-held sensor and the acceleration sensor.

The photographing unit is conductively connected with the controller, includes at least one camera, and enters a photographing mode according to a control signal of the controller. The shooting mode includes a photographing mode or a shooting mode, which can be set in advance.

Specifically, in Embodiment 1, according to the user's action of using the camera to shoot, first, hold the camera, and set the hand-held sensor and the acceleration sensor respectively in the action step of turning the camera sideways to take a landscape shot. When the camera is in the non-shooting mode, use the grip sensor to detect whether the effective touch areas of the four frames of the camera are touched by fingers at the same time. Whether the mobile phone enters the camera shooting mode.

In this way, the camera adopts the combined application of border touch area judgment + acceleration motion recognition judgment, which effectively avoids misjudgment caused by unintentional changes in the camera position, and improves the intelligence of the camera.

Those skilled in the art should know that the camera in the shooting unit may be a CCD camera or a CMOS camera, as long as it can execute the shooting mode. Those skilled in the art should also know that there should be a video processor in the shooting unit to process the captured photos or videos, and the shooting unit should have the components of a conventional shooting unit.

Example 2:

Referring to accompanying drawings 2 and 3, it specifically describes the schematic diagram of the specific implementation of the hand grip sensor and its corresponding working principle. Wherein, FIG. 2 is a schematic diagram of a specific implementation of a handhold sensor of a camera that quickly enters a shooting mode according to an embodiment of the present invention.

In FIG. 2 , the hand grip sensor includes a signal generator (not shown in the figure) and at least one set of external electrodes. The set of external electrodes includes at least one emitting electrode 5 and at least one sensing electrode 6 . The external electrodes are correspondingly placed on the frame parallel to the same direction of the camera. The frames parallel in the same direction may be a pair of horizontally parallel frames, or a pair of vertically parallel frames. The area where the emitting electrode 5 and the sensing electrode 6 are located is the effective touch area.

Referring to FIG. 3 , the signal generator generates multiple transmit signals with a certain period and a certain amplitude. FIG. 3 schematically shows a square wave signal with a period of 10 microseconds, an amplitude of 2.5V, and a maximum number of 1024 square wave signals. It should be understood that the signal generator can be generated by an integrated circuit, and in one embodiment, a square wave signal is generated by a sine wave generator inside the integrated circuit. The period, amplitude and quantity of these square waves can be controlled by software.

The amplitude of the emission signal generated by the signal generator can be controlled, and the distance between the emission electrode and the sensing electrode can be adjusted, so that when the human hand does not touch the emission electrode 5 and the sensing electrode 6 at the same time, the sensing electrode 6 cannot sense the emission of the emission electrode. When the human hand touches the transmitting electrode and the sensing electrode at the same time, the transmitting signal such as a pulse square wave on the transmitting electrode 5 is transmitted to the sensing electrode 6 through the human body. At this time, the transmitting signal of the sensing electrode 6 increases. When the number is counted, an interrupt is generated to prompt the camera system, and the hand is holding the camera at this time. Therefore, it is possible to detect whether the camera is in a hand-held state through the hand-hold sensor.

The signal generator can always generate the emission signal, and the signal generator can also be turned on in the camera to generate the emission signal.

It should be known that the number of groups of external electrodes can be set as required, as long as they are placed correspondingly on a pair of frames parallel to the same direction of the camera. For example, it can be set on the long side (portrait) or on the short side (landscape). In a preferred embodiment, two sets of external electrodes can be arranged on the long side (longitudinal direction). The positions of the emitting electrode 5 and the sensing electrode 6 are not limited, as long as they are respectively located on a corresponding pair of frames in the same direction of the camera.

Example 3:

In this embodiment, a smart phone or a tablet computer is disclosed, which includes a camera that can quickly enter the shooting mode as in the above-mentioned embodiments 1 and 2. At this time, the hand-held sensor unit, the acceleration sensor, the controller, and the shooting unit All are components of a smartphone or tablet.

At this time, the set of external electrodes of the grip sensor is located on a pair of parallel frames in the same direction of the smart phone or tablet computer, which may be a pair of horizontally parallel frames, or a pair of longitudinally parallel frames . Accelerometers are located in smartphones or tablets.

In this way, when the user holds the effective touch area of the outer frame of the smart phone or the tablet computer, the hand sensor feels the user's touch, and the acceleration sensor judges whether the user performs a horizontal screen operation, thereby quickly starting the smart phone or tablet computer. The shooting unit, that is, the camera, enables the user to quickly capture wonderful pictures, and the usage habits are exactly the same as the user's normal photo taking habits, omitting the cumbersome process of unlocking - entering the main menu interface - selecting a submenu - activating the corresponding program process.

S130, the acceleration sensor judges whether the terminal has a horizontal screen movement, if yes, enters S140, otherwise, enters S120;

S140. The terminal enters a shooting mode.

Here, the terminal refers to a camera, a smart phone or a tablet computer, and the signals obtained by the hand sensor and the acceleration sensor are transmitted to the controller, and finally the controller starts the shooting unit to enter the shooting mode in S140.

Those skilled in the art should know that the controller can be a hardware circuit that executes the method in Embodiment 4, or it can be a combination of a microprocessor and a storage medium, and a program is stored in a computer-readable storage medium, and the storage The medium can be such as: ROM/RAM, magnetic disk, optical disk, etc. The control function is realized by reading the program from the storage medium by the microprocessor (CPU).

To sum up, referring to FIG. 5 , FIG. 5 is a schematic diagram of how the camera quickly enters the shooting mode according to an embodiment of the present invention. When the user holds a smart phone or tablet computer, the hand sensor on the outside of the smart phone or tablet computer gets the signal of the user holding the terminal, and further according to the user's horizontal screen movement obtained by the acceleration sensor, immediately starts the shooting unit to enter the shooting mode.
