Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The mobile phone can improve the appearance by presenting a certain display effect when the screen is awakened, but the display content is usually limited to a desktop or a screen locking interface and the like. The embodiment of the disclosure provides a display control method, wherein a plurality of images for visual test are inserted before displaying conventional display contents, so that on one hand, a user can be assisted in testing own color vision, on the other hand, interestingness in use can be increased, and use experience of the user is improved.
Fig. 1 is a flowchart illustrating a display control method according to an exemplary embodiment, where the method is applicable to a mobile phone, a tablet computer, a personal computer, and the like, and an embodiment of the disclosure is described by taking a mobile phone as an example. The display control method comprises the following steps 101-103:
in step 101, after receiving a screen lighting instruction, a first image displayed after lighting the screen is determined.
The screen lighting instruction is used for indicating to light the mobile phone screen. In one embodiment, when the power key is pressed while the mobile phone is in the off-screen state, the screen lighting instruction is triggered, and the mobile phone screen is lighted. Or when the mobile phone is in a screen-off state and a user double-clicks the touch screen, the screen lighting instruction is triggered, and the screen is lighted at the moment.
The first image may be a screen saver image, a desktop image, or an application interface image, etc. The present disclosure is not limited to the specific content of the first image.
In step 102, at least one second image is displayed.
The second image is generated according to the first image and has a different hue from the first image.
In one embodiment, the first image is an RGB image, and the second image includes any one or two of RGB (red green blue) pixels of the first image.
For example, the second image includes R pixels, or G pixels, or B pixels of the first image.
For another example, the second image includes R pixels and G pixels, or R pixels and B pixels, or G pixels and B pixels of the first image.
In one embodiment, a pixel drive circuit of a display may turn off a drive signal of one or both pixels of a first image or reduce a driving force of the drive signal, thereby displaying a second image.
In one embodiment, a second image is generated and displayed by adding or subtracting a certain value to the pixel value of one or both pixels of the first image.
The number of second images is denoted as K, which is an integer greater than or equal to 1. When K is greater than 1, the K second images differ in hue from one another.
In one embodiment, the mobile phone displays the K second images in sequence in the same display area according to a preset sequence. Referring to fig. 2, the display area 21 is a rectangular area on the display screen, and is indicated by hatching in fig. 2. The display area 21 may occupy a proportion of or the entirety of the display screen. In the display area 21, the K second images are displayed one by one. Optionally, the display duration of each second image is a preset value, for example, set to 0.5 second, that is, another second image is updated and displayed every 0.5 second. Alternatively, each time the user clicks the screen, another second image is displayed in an updated manner.
In step 103, a first image is displayed.
And after the second image is displayed, normally displaying the first image when a certain trigger condition is met. For example, when the first image is an RGB image, the first image is normally displayed according to the pixel value of the first image when the trigger condition is satisfied.
In one embodiment, the first image is displayed when the length of time for which the screen is lit reaches a preset length.
For example, in the R pixel, the G pixel, and the B pixel of the first image, when only one pixel is turned on, the second image is displayed, and when the time length for waking up the screen reaches a preset value, all three pixels are turned on, and at this time, the first image is displayed.
Specifically, in step 102, at T1Lighting R pixel in the first image at time point, T2At a time point, the G pixels in the first image are turned on and the R pixels are turned off, and at T3The time point lights up the B pixels and lights out the G pixels in the first image. In step 103, when the time length for waking up the screen reaches a preset value, the R pixel, the G pixel, and the B pixel of the first image are all lit, and the first image is normally displayed.
For another example, when two pixels among the R pixel, the G pixel, and the B pixel of the first image are lit, the second image is displayed, and when the time length for waking up the screen reaches a preset value, all three pixels are lit, and at this time, the first image is displayed.
Specifically, in step 102, at T1Lighting R pixel and G pixel in the first image at time point, and displaying the first image at T2At time point, keeping the R pixel on continuously, lighting the B pixel in the first image, turning off the G pixel, and at T3At the time point, the B pixel is kept on, and the G pixel in the first image is turned on to turn off the R pixel. In step 103, when the time length for waking up the screen reaches a preset value, the R pixel, the G pixel, and the B pixel of the first image are all lit, and the first image is normally displayed.
It is to be noted that the R, G, B pixels of the second image may have pixel values equal to the R, G, B pixels of the first image, or may have different pixel values, for example, a certain value may be added or subtracted from the pixel values of the first image, so that the hue of the second image is different from that of the first image.
The display control method provided by the present disclosure determines a first image displayed after lighting a screen when the screen is lighted, and displays a second image after first displaying at least one second image. The second image is generated according to the first image, and the second image has a different hue from the first image. When the screen is just lighted, before the display of the conventional display content, the images with different hues from the conventional display content are displayed, on one hand, the images can assist the user to test the color vision of the user, and the user can know whether the user has color vision defects or not by identifying and perceiving the difference between the first image and the second image or the difference between two or more second images.
Based on the display control method provided in the embodiment corresponding to fig. 1, fig. 3 is a flowchart illustrating a display control method according to an exemplary embodiment, and in the embodiment corresponding to fig. 3, the process from the screen lighting to the final switching to the first image is further supplemented and explained.
The content of some steps is the same as or similar to the steps in the corresponding embodiments of fig. 1-2, and only the differences in the steps will be described in detail below. Referring to fig. 3, the display control method provided in this embodiment includes steps 301-305:
in step 301, after receiving a screen lighting instruction, a first image displayed after lighting the screen is determined.
In one embodiment, the first image is a pre-stored image for color vision testing.
The content of the first images can be various, the mobile phone can prestore a plurality of first images and divide the first images into a plurality of groups, and one group can comprise one or more than one first image.
For example, the first image is divided into a plurality of contrast color image groups, and the contrast color image groups may include a complementary color image group, a cooling and heating image group, and the like, and the embodiments of the disclosure do not limit the content of the first image. The handset may provide a settings interface and the user may specify a group from a plurality of groups. After receiving the screen lighting instruction, the mobile phone determines any one of the images in the user-specified group as a first image.
In step 302, at least one second image is displayed.
In one embodiment, the first image is a physical image, such as a landscape image or the like. Illustratively, the test image is a street view image, and the content of the image comprises: green trees, blue sky, yellow telephone booth, red fire hydrant. Referring to the display interface shown in fig. 2, after the screen is lit, the sky portion, the tree portion, the telephone booth portion, and the hydrant portion in the image are sequentially displayed in the display area 21.
The R, G, B pixel values of each portion may be equal to or different from the R, G, B pixel values of the first image, for example, the hue of the second image may be different from that of the first image by adding or subtracting a certain value to or from the pixel values of the first image.
In one embodiment, the display screen is divided into K display areas, and K second images are displayed in the K display areas, respectively. Referring to fig. 4, taking the case that K takes a value of 4 as an example, the display screen is divided into 4 display areas, and the 4 display areas are a first area 41, a second area 42, a third area 43, and a fourth area 44. The 4 display regions may display 4 second images, respectively.
The 4 areas may simultaneously display the 4 second images or sequentially display the 4 second images at a certain time interval. The display order and the display time interval of each second image are not limited in the embodiments of the present disclosure, and only a case where the second images are sequentially displayed at a certain time interval is taken as an example for explanation.
For example, the user-specified images are grouped into a set of contrasting color images that include a color card map of several contrasting colors. With the time point when the screen is lit as the 0 time point, the first area 41 displays a red color patch image at the 0 time point, the second area 42 displays a yellow color patch image at the 0.4 second time point, the third area 43 displays a blue color patch image at the 0.8 second time point, and the fourth area 44 displays a green color patch image at the 1.2 second time point.
In step 303, image specification information is displayed.
The image description information comprises L pieces of description contents of the displayed second images for L people with different color senses, wherein L is more than or equal to 2.
In one embodiment, the image description information and the second image are displayed on the screen without being occluded. Referring to fig. 5, when 4 display regions of the screen sequentially display red, yellow, blue, and green color card images, the image description information may be: "display order is: red, yellow, blue, green B red, yellow, blue, red C red, yellow, green.
Assume A, B, C that the description of the second image is a person with normal color vision, a person with obstacle in green color, and a person with obstacle in blue color, respectively.
In step 304, color vision specification information is displayed upon receipt of the selection instruction.
The selection instruction is used for selecting one of the L pieces of descriptive contents, and the color vision explanation information is used for explaining the color vision characteristics corresponding to the selected piece of descriptive content.
Referring to the display interface shown in fig. 5, when the user clicks one of the options, the image specification information is switched to the color vision specification information, and the display interface of the color vision specification information is shown in fig. 6.
When the user clicks the option C, the color vision instruction information indicates the color vision characteristics of the person with blue obstacle, for example, the color vision instruction information may be: "unclear blue recognition", etc.
In step 305, a first image is displayed when a preset trigger condition is met.
Step 305 may be performed after any of steps 302-304.
In one embodiment, the first image is displayed after the color vision instruction information is displayed.
Referring to fig. 5, when the user clicks on option B, color vision explanatory information is displayed. The first image is displayed when the color vision interpretation information display time reaches a preset time length (for example, 0.3 second).
In one embodiment, the first image is displayed upon receiving an instruction to exit displaying the second image.
Referring to fig. 5, when the user clicks the exit icon on the upper right corner of the screen, the mobile phone triggers an exit instruction, and at this time, the display content displays the first image.
In one embodiment, the first image is displayed when the length of time for which the screen is lit reaches a preset length. For example, when the length of time the screen is on reaches 1.5 seconds from the point of time the screen is on, the first image is displayed.
The display control method provided by the embodiment of the disclosure determines a first image displayed after the screen is lighted when the screen is lighted, and displays a second image after at least one second image is displayed at first. The second image is generated according to the first image, and the second image has a different hue from the first image.
