Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
An embodiment of the present invention provides a method for adjusting a pixel of a terminal application interface, as shown in fig. 1, the method specifically includes the following steps:
101. and the terminal acquires the aspect ratio of the target pixel of the application interface to be adjusted.
The terminal in the embodiment of the invention is a smart phone or a tablet computer (called android terminal for short) provided with an android system. The application interface to be adjusted includes a preview interface of the camera of the terminal or a video playing interface of the terminal, and the video playing interface of the terminal may be a video playing interface of the camera in the shooting mode or a video playing interface of a video playing application installed in the terminal.
Specifically, when a user adjusts pixels of an application interface installed in the terminal, the aspect ratio of the target pixel of the application interface to be adjusted may be obtained from a preconfigured application interface pixel database according to actual needs or personal preferences, for example, when the user takes a picture through a camera module of the terminal, the user may select different proportions of the taken picture pixels from the user interface pixel database according to his preferences. And when the terminal is performing the camera test, the aspect ratio of the target pixel of the application interface to be adjusted is the same as the output ratio of the imaging unit sensor of the terminal camera. For example, when the pixels of the application interface to be adjusted are: 640 x 480, the aspect ratio of the corresponding target pixel is 4: 3.
102. The terminal determines a display area of the application interface to be adjusted on a terminal screen, and obtains the height and the width of the display area.
Specifically, the height of the display area of the application interface to be adjusted is obtained by subtracting the heights of the application interface layout file and the control frame from the screen height of the terminal, and the width of the display area of the application interface to be adjusted is obtained by subtracting the widths of the application interface layout file and the control frame from the screen width of the terminal.
103. And the terminal calculates the first pixel width and the first pixel height of the display area according to the target pixel aspect ratio, the height of the display area and the width of the display area of the application interface to be adjusted.
The first pixel width and the first pixel height are the pixel width and the pixel height of the optimal undistorted picture which can be displayed when the display area displays the image according to the target pixel width-height ratio of the application interface to be adjusted. For example, when the width of the display area is greater than the product of the height of the display area and the aspect ratio of the target pixel of the application interface to be adjusted, the optimal undistorted picture that can be displayed by the display area, that is, the image that can be displayed when the pixel height of the image is the height of the display area and the image is not distorted, is displayed.
Optionally, step 103 specifically includes the following steps:
103a, when the width of the display area is larger than the product of the height of the display area and the target pixel aspect ratio of the application interface to be adjusted, the terminal takes the height of the display area as the first pixel height of the display area, and the product of the height of the display area and the target pixel aspect ratio of the application interface to be adjusted is rounded as the first pixel width of the display area.
Or,
103b, when the width of the display area is smaller than or equal to the product of the height of the display area and the target pixel aspect ratio of the application interface to be adjusted, the terminal takes the width of the display area as the first pixel width of the display area, and takes the product of the width of the display area and the target pixel aspect ratio of the application interface to be adjusted as the first pixel height of the display area.
Specifically, when the Width of the display area of the application interface to be adjusted is greater than the product (i.e., Height × R) of the Height of the display area and the target pixel Width-to-Height ratio R of the application interface to be adjusted, the terminal may calculate the first pixel Width 'and the first pixel Height' of the display area according to the following formula one. When the Width of the display area of the application interface to be adjusted is less than or equal to the product (i.e., Height R) of the Height of the display area and the pixel Width-to-Height ratio R of the application interface to be adjusted, the terminal can calculate the first pixel Width 'and the first pixel Height' of the display area according to the following formula two.
Formula one
Formula two
Exemplarily, when the pixel aspect ratio R of the application interface to be adjusted is 16:9, and the Width is 640, and the Height is 480; first, it is determined that the first pixel Width 'and the first pixel Height' of the display region are calculated using the formula two since the Height R is 480 (16/9) is 853.3 and 853.3>640, where:
Width'＝Width＝640；
height' ═ Width/R +0.5 ═ 640/(16/9) +0.5 ═ 360. ([ ] represents rounding)
When the pixel aspect ratio R of the application interface to be adjusted is 4:3, the Width is 868, and the Height is 576; first, it is determined that the first pixel Width 'and the first pixel Height' of the display region are calculated using formula one because 768<868, where:
Width'＝[Height*R+0.5]＝[576*(4/3)+0.5]＝768；
Height'＝Height＝576。
104. and the terminal acquires the optimal application interface pixel from a pre-configured application interface pixel database according to the target pixel aspect ratio and the first pixel width or the first pixel height of the application interface to be adjusted.
The application interface pixel database stores application interface pixels supported by the terminal.
Specifically, when the terminal selects an optimal application interface pixel from the application interface pixel database according to the target pixel aspect ratio and the first pixel width or the first pixel height of the application interface to be adjusted, the optimal application interface pixel needs to satisfy: when the width of the display area is larger than the product of the height of the display area and the target pixel width-height ratio of the application interface to be adjusted, the difference value between the display area and the pixel width-height ratio of the application interface to be adjusted is in a preset range or 0, and the difference value between the display area and the first pixel width is minimum; or, the difference with the first pixel width is minimum; when the width of the display area is smaller than or equal to the product of the height of the display area and the target pixel aspect ratio of the application interface to be adjusted, the difference value between the display area and the pixel aspect ratio of the application interface to be adjusted is within a preset range or 0, and the difference value between the display area and the first pixel height is minimum; or, the difference from the first pixel height is minimum.
Optionally, step 104 specifically includes the following steps:
104a, the terminal matches the pixel aspect ratio of the application interface to be adjusted with the pixel aspect ratio of each application interface pixel in the application interface pixel database.
If the application interface pixel database includes a target application interface pixel having the same aspect ratio as the pixel of the application interface to be adjusted, or a target application interface pixel having a difference value with the aspect ratio of the pixel of the application interface to be adjusted within a predetermined range, the process goes to step 104b1, and if the application interface pixel database does not include a target application interface pixel having the same aspect ratio as the pixel of the application interface to be adjusted and a target application interface pixel having a difference value with the aspect ratio of the pixel of the application interface to be adjusted within a predetermined range, the process goes to step 104 c.
104b1, the terminal acquires the target application interface pixel set.
The target application interface pixel set comprises target application interface pixels with the same aspect ratio as the pixels of the application interface to be adjusted, or target application interface pixels with the aspect ratio difference value of the pixels of the application interface to be adjusted within a preset range. That is, the difference between the aspect ratio of the target application interface pixel in the target application interface pixel set and the aspect ratio of the pixel of the application interface to be adjusted is 0 or within a preset range.
104b2, when the width of the display area is larger than the product of the height of the display area and the aspect ratio of the target pixel of the application interface to be adjusted, the terminal selects the target application interface pixel with the minimum difference with the first pixel width from the application interface pixel set according to the first pixel width as the optimal application interface pixel; or when the width of the display area is smaller than or equal to the product of the height of the display area and the aspect ratio of the target pixel of the application interface to be adjusted, the terminal selects the target application interface pixel with the minimum difference value with the height of the first pixel from the application interface pixel set according to the height of the first pixel as the optimal application interface pixel.
104c, if the application interface pixel database does not contain a target application interface pixel which is the same as the pixel aspect ratio of the application interface to be adjusted or a target application interface pixel of which the difference value with the pixel aspect ratio of the application interface to be adjusted is in a preset range, and the width of the display area is greater than the product of the height of the display area and the target pixel aspect ratio of the application interface to be adjusted, selecting the application interface pixel with the minimum difference value with the first pixel width from the application interface pixel database as an optimal application interface pixel by the terminal according to the first pixel width; or, if the application interface pixel database does not contain the target application interface pixel with the same pixel aspect ratio as the application interface to be adjusted, and the width of the display area is less than or equal to the product of the height of the display area and the target pixel aspect ratio of the application interface to be adjusted, selecting the application interface pixel with the smallest difference with the first pixel height from the application interface pixel database as the optimal application interface pixel according to the first pixel height.
In this embodiment, the terminal first matches the aspect ratio of the target pixel of the application interface to be adjusted with the aspect ratio of each application interface pixel in the application interface pixel database, if an application interface pixel is selected from the aspect ratios of the target pixel of the application interface to be adjusted, the selected application interface pixel is further screened according to the first pixel height or the first pixel width, and an optimal application interface pixel is screened from the application interface pixels, if an application interface pixel having the same aspect ratio as the target pixel of the application interface to be adjusted cannot be found, the first pixel height or the first pixel width is directly matched with each application interface pixel in the application interface pixel database, and the optimal application interface pixel is screened from the application interface pixel database.
For example, when the adjustment application interface is a preview interface of a terminal camera, if the Width-to-Height ratio R of the target pixel of the interface to be previewed is 4:3, the Width of the maximum display area of the preview interface is 868, and the Height is 576.
First, the first pixel Width '768 and the first pixel Height' 576 of the display area are calculated according to the formula two.
Then, based on R4: 3 and (Width 768), an application interface pixel with a pixel Width/height ratio of 4:3 and a similar pixel Width 768 is found from the application interface pixel database. For example 770 x 578.
105. And the terminal adjusts the current pixel of the application interface to be adjusted into the optimal application interface pixel.
The method for adjusting the pixels of the terminal application interface, provided by the embodiment of the invention, comprises the steps of obtaining the aspect ratio of target pixels of an application interface to be adjusted; determining a display area of an application interface to be adjusted; acquiring the height and the width of a display area; calculating a first pixel width and a first pixel height of a display area according to a target pixel aspect ratio of an application interface to be adjusted, the height of the display area and the width of the display area; acquiring an optimal application interface pixel from a pre-configured application interface pixel database according to the aspect ratio of a target pixel of an application interface to be adjusted and the width or height of a first pixel; and adjusting the current pixel of the application interface to be adjusted into the optimal application interface pixel.
Compared with the prior art, when the screen size proportion of the Android terminal is not consistent with the sensor output proportion of the camera module, in order to achieve undistorted preview, the Android generally matches Android devices with different size proportions by cutting a preview picture. According to the method, the aspect ratio of the target pixel according to the application interface to be adjusted is set, and then the optimal application interface pixel corresponding to the application interface to be adjusted under different aspect ratios of the target pixel is calculated. Therefore, full-view or full-screen display can be realized under the condition of ensuring no distortion of the picture of the terminal application interface, and the user experience is improved.
Example two
The second embodiment of the invention is mainly applied to an application scene of performing power detection on the android terminal camera module in the factory mode. In the prior art, in order to quickly and accurately judge the performance of each part of a produced android terminal and find out defective products in time during factory production, each part of the android terminal is usually subjected to power inspection at the initial stage of production. For the camera module test in the power inspection test, when the screen size ratio of the android terminal is not consistent with the sensor output ratio of the camera module, the android system usually cuts the preview picture for undistorted preview picture. However, this generally has the following problems:
specifically, if this camera module exists the quality problem (e.g., the vignetting problem, there is black dark line in preview picture or the photo corner of shooing promptly, or the red line problem, it appears red bright line in the twinkling of an eye to shoot promptly), if need tailor the picture this moment, can lead to cutting the back and cover vignetting or red line problem just so, make testing personnel just think the camera qualified by mistake, in case this problem is not detected, lead to the problem product to flow into the market, not only can seriously influence consumer's user experience, still can seriously influence producer's reputation and profit.
In order to solve the above problem, a second embodiment of the present invention provides a method for adjusting a pixel of a terminal application interface, where in this embodiment, an application interface to be adjusted is a preview interface of the terminal camera, as shown in fig. 2, the method specifically includes the following steps:
201. the terminal selects a photographed pixel for the terminal camera from the application interface pixel database.
The aspect ratio of the photographing pixel is a target aspect ratio of the application interface to be adjusted.
In this embodiment, when a user uses the terminal camera to take a picture normally, if the user wants to adjust the pixels of the preview interface of the terminal camera, a taking pixel needs to be set for the terminal camera first, and the aspect ratio of the taking pixel may be any ratio set by the user.
In addition, in this embodiment, when the terminal needs to test the camera of the terminal in the factory mode, the terminal needs to be set for the photographing pixel of the terminal in advance. For production detection angle considerations, the application interface pixel with the same output ratio as the sensor is selected as the photographed pixel from a pre-configured application interface pixel database by default. This is a prerequisite for achieving undistorted panoramic previews.
202. And the terminal acquires the aspect ratio of the target pixel of the application interface to be adjusted.
203. The terminal determines a display area of the application interface to be adjusted on a terminal screen, and obtains the height and the width of the display area.
204. And the terminal calculates the first pixel width and the first pixel height of the display area according to the target pixel aspect ratio, the height of the display area and the width of the display area of the application interface to be adjusted.
205. And the terminal acquires the optimal application interface pixel from a pre-configured application interface pixel database according to the target pixel aspect ratio and the first pixel width or the first pixel height of the application interface to be adjusted.
206. And the terminal adjusts the current pixel of the application interface to be adjusted into the optimal application interface pixel.
Specifically, the detailed process from step 202 to step 206 may refer to step 101 to step 105 in the first embodiment, and is not described herein again in the embodiments of the present invention.
The method for adjusting the pixels of the terminal application interface, provided by the embodiment of the invention, comprises the steps of obtaining the aspect ratio of target pixels of an application interface to be adjusted; determining a display area of an application interface to be adjusted; acquiring the height and the width of a display area; calculating a first pixel width and a first pixel height of a display area according to a target pixel aspect ratio of an application interface to be adjusted, the height of the display area and the width of the display area; acquiring an optimal application interface pixel from a pre-configured application interface pixel database according to the aspect ratio of a target pixel of an application interface to be adjusted and the width or height of a first pixel; and adjusting the current pixel of the application interface to be adjusted into the optimal application interface pixel.
Compared with the prior art, when the screen size proportion of the android terminal is inconsistent with the sensor output proportion of the camera module, the android system carries out a cutting process on a preview picture for the undistorted preview picture. When the camera module is detected, the photographing pixels which are the same as the photographing pixels of the output proportion of the sensor in the camera module are set, then the pixel width-height ratio of the preview interface of the terminal camera is the same as the output proportion of the sensor, and then the optimal application interface pixels of the preview interface under the pixel width-height ratio are calculated according to the set pixel width-height ratio of the preview interface, so that full-view angle display with equal proportion and no zooming is realized, a production line worker is facilitated to detect the quality of each imaging part of the camera module of the terminal camera module, missing detection of a problem product is avoided, and the power detection efficiency of a manufacturer is improved.
