Referring to fig. 1, fig. 1 shows a schematic structural diagram of an electronic device suitable for implementing an embodiment of the present disclosure. It should be noted that the electronic device 100 shown in fig. 1 is only an example, and should not bring any limitation to the functions and the scope of the application of the embodiments of the present disclosure.

The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

The processor 110 may include one or more processing units, for example, the processor 110 may include an application processor, a modem processor, a graphics processor, an image signal processor, a controller, a video codec, a digital signal processor, a baseband processor, and/or a neural network processor, among others. The different processing units may be separate devices or may be integrated into one or more processors.

If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory, avoiding repeated accesses, reducing the latency of the processor 110, and thus increasing the efficiency of the system.

The display screen 170 is used to display images, video, and the like. The display screen 170 includes a display panel. The display panel can be a liquid crystal display, an organic light emitting diode, an active matrix organic light emitting diode or an active matrix organic light emitting diode, a flexible light emitting diode, etc.

The technical solutions of the embodiments of the present disclosure are explained in detail below.

At present, place the camera in the technique of realizing the full screen below the display screen, include: mechanical pop-up, screen opening, etc. Mechanical ejection refers to ejecting a camera by a mechanical method when the camera is used. Although the method ensures the imaging quality of the camera, the display effect of the screen is also ensured. But the reliability, cost and thickness of the product are adversely affected by the application of additional mechanical structures.

In the screen trompil scheme, in camera light passing area, if there is not the pixel structure in the display screen, although can guarantee the imaging quality of camera, because the screen can not show in camera light passing area, consequently the display effect can receive the influence.

In the screen-cut scheme, if a pixel structure is included in the display screen in the camera light-transmitting area, the structure can be seen in fig. 2 and 3, respectively, and in the side view of fig. 2, the under-screen camera 210 is located below the display screen 220. In the front view of fig. 3, the enlarged view of the head light-passing area 320 in the display screen 310 can be seen in the right-side dashed box, and it can be seen that the pixels 330 are uniformly distributed. At this moment, the screen display effect of camera light-passing area and the imaging effect of camera need be guaranteed simultaneously. The light transmittance of the pixel part in the display screen is low, and the thin film transistor and the circuit connecting wire thereof in the screen also form a complex structure, so that the imaging quality of the camera is reduced, including the reduction of the resolving power, the generation of the starburst phenomenon and the like. The starburst belongs to the special phenomenon of light diffraction, and is formed after light is diffracted and scattered in the transmission process.

In order to solve the above problems, the present disclosure provides a pixel position determining method, a pixel position determining apparatus, an electronic device, and a computer-readable storage medium, which improve the imaging quality of a camera by determining the position of each pixel in a display screen when designing the display screen before the electronic device leaves a factory.

Referring to fig. 4, fig. 4 shows a flowchart of a pixel location determination method of an embodiment of the present disclosure, which may include the following steps:

step S410, acquiring position coordinates of each pixel preset in the light transmission region of the off-screen camera.

Step S420, respectively updating the positions of the pixels, wherein the position offsets corresponding to the pixels during the position updating are not completely the same and are all smaller than the offset threshold.

And step S430, after the position of each pixel is updated, acquiring an image through the under-screen camera, and determining the quality of the acquired image.

Step S440, determining whether the quality of the acquired image meets a preset condition. If the preset condition is not met, returning to the step S420; when the preset condition is satisfied, step S450 is performed.

In step S450, the position coordinates of each pixel after the last position update are used as the final position coordinates of each pixel.

In the pixel position determining method of the embodiment of the disclosure, the positions of the pixels in the display screen are updated, so that diffraction generated by the pixels in the display screen can be reduced, the influence of the diffraction on the image quality is further reduced, and the image quality of the camera under the screen is improved. Moreover, when the position of the pixel is updated, the influence on the display effect of the display screen can be reduced because the position offset is small. Therefore, the imaging quality of the camera under the screen can be improved, the display effect of the display screen is not reduced, and the user experience can be improved.

The pixel position determining method according to the embodiment of the present disclosure is described in more detail below.

In step S410, position coordinates of each pixel set in advance in the light-transmitting area of the off-screen camera are acquired.

In the embodiment of the present disclosure, the off-screen camera refers to a camera disposed below a display screen of an electronic device, and the electronic device may be a full-screen electronic device. Since the position coordinates of each pixel do not refer to the position coordinates of each pixel in the display screen after the electronic device is produced. Therefore, the position coordinates of each pixel set in advance may be the position coordinates of each pixel in the display screen of the electronic device in the related art. That is, the position coordinates of each pixel in the display screen can be newly determined on the basis of the prior art.

The light-transmitting area of the under-screen camera is located on a display screen, and pixels in the display screen can be arranged periodically, and correspondingly, the pixels in the light-transmitting area can also be arranged periodically. In general, the anode of a screen pixel has a low transmittance or even no transmittance, so that the periodically arranged pixels act as an amplitude-type two-dimensional grating and diffract incident light. In order to eliminate the diffraction phenomenon and improve the imaging quality of the camera, the position of the pixel in the light-transmitting area can be updated. Therefore, the position coordinates of each pixel in the light-transmitting area can be acquired first. The present disclosure may use the lower left corner of the display screen as an origin, the horizontal direction as an X axis, and the vertical direction as a Y axis to establish a coordinate system, or may use the lower left corner of the light-transmitting area as an origin, the horizontal direction as an X axis, and the vertical direction as a Y axis to establish a coordinate system, and the like, which is not limited herein.

In step S420, the positions of the pixels are updated.

In the embodiment of the present disclosure, the pixels arranged periodically form a grating to generate a diffraction phenomenon, and in order to eliminate the diffraction phenomenon, the position of each pixel may be updated, that is, each pixel is moved to change its position. It should be noted that the execution subject of the present disclosure may be the electronic device itself, for example, a processor in the electronic device may control the movement of each pixel in the display screen. In addition, another electronic device (for example, a desktop computer, a portable computer, etc.) may be used to control the movement of each pixel in the display screen of the electronic device.

Because the display effects of different display screens are different, that is, the distances between the pixels in different display screens are different, when the position of each pixel is updated, the position offset corresponding to each pixel can be determined according to the position coordinates of each pixel. The position offset amount represents the magnitude of the pixel shift, and may include: a lateral position offset and a longitudinal position offset. Referring to fig. 5, fig. 5 shows a schematic diagram of pixel position update in the embodiment of the present disclosure, where black represents an original position of a pixel, gray represents a position of the pixel after the position is thinner, and Δ x and Δ y represent a lateral position offset and a longitudinal position offset, respectively.

It should be noted that, if the position offset corresponding to each pixel during the position update is completely the same, which is equivalent to that each pixel has performed an overall translation, the influence on the imaging effect of the camera before and after the translation is the same, and the purpose of improving the imaging effect of the camera cannot be achieved. Therefore, the amount of positional shift corresponding to each pixel at the time of position update is not exactly the same. That is, the amount of positional shift corresponding to each pixel at the time of position update may be completely different, or may be partially the same or partially different.

In the embodiment of the present disclosure, the position offset amount of each pixel may be determined according to the position coordinate of each pixel. The method specifically comprises the following steps:

first, the distance between the pixels can be determined from the position coordinates of the pixels. For example, for the periodically arranged pixels, the lateral distances and the longitudinal distances between any adjacent pixels are the same before the position update is performed. The transverse distance and the longitudinal distance may be the same or different. Accordingly, it may be determined that the pixel arrangement period of the display screen includes: a transverse alignment period and a longitudinal alignment period. The horizontal arrangement period is the horizontal distance between adjacent pixels, and the vertical arrangement period is the vertical distance between adjacent pixels.

Then, the positional shift amount of each pixel is determined based on the distance, i.e., the lateral arrangement period and the longitudinal arrangement period. It can be understood that if the pixel position offset is too large, the human eye can distinguish the pixel position offset, and the display effect of the display screen will be affected. In order to reduce the influence on the screen display effect, each pixel can correspond to a small position offset. For example, the position offset amount of each pixel may be smaller than an offset amount threshold, where the position offset amount of each pixel refers to an overall position offset amount obtained by superimposing the lateral position offset amount and the longitudinal position offset amount. The offset threshold may be one tenth, one fifteenth, etc. of the pixel arrangement period, and is not limited herein. Experiments show that when the offset threshold is one tenth of the pixel arrangement period, the camera has a good imaging effect, and the display effect of the display screen is not affected.

After the position offset of each pixel is determined, the position of each pixel is updated according to the position offset corresponding to the pixel.

In the embodiment of the disclosure, images can be collected by the camera under the screen, and the imaging effect of the camera after the updating of each pixel position is checked according to the quality of the images. The image here may be a complete image or an image in a light-transmitting region. It is assumed that the lens in the under-screen camera is an ideal optical lens without any aberration. When there is no display screen, the image of the point source at infinity in the camera is also an infinitesimal point. When there is a display screen, the diffraction of light by the display screen can increase the amount of diffuse light. The diffuse speckle refers to the light intensity distribution of diffraction images formed on different sections of the front and the back of an image surface after a point light source passes through an optical system.

Thus, the quality of the image can be characterized by the size of the diffuse spot, which can be the radius, diameter, etc. of the diffuse spot. Specifically, the size of the diffuse spot of the acquired image can be determined; based on the size, the quality of the image is determined. Depending on the quality of the image, the magnitude of the display screen diffraction effects can be determined. That is, the magnitude of the display screen diffraction effect can be quantitatively characterized by the size of the diffuse spot. Of course, the quality of the image may be characterized in other ways besides the diffuse spot, and is not limited herein.

In the embodiment of the present disclosure, after the positions of the pixels are updated, the quality of the acquired image may still not meet the preset condition, and at this time, the step S420 may be returned to, and the positions of the pixels are updated for multiple times in a cyclic manner. When the quality of the acquired image satisfies the preset condition, the step S450 is directly performed.

In one implementation of the present disclosure, the position offset corresponding to each pixel may be determined based on an optimization algorithm. The optimization algorithm may include: particle swarm algorithm, genetic algorithm, etc., and are not limited herein. Accordingly, the optimization goal of the optimization algorithm may be to minimize the size of the diffuse spot. The basic core of the particle swarm optimization is that the movement of the whole swarm generates an evolution process from disorder to order in a problem solving space by sharing information by individuals in the swarm, so that the optimal solution of the problem is obtained. A genetic algorithm is a method of searching for an optimal solution by simulating a natural evolution process. The algorithm converts the solving process of the problem into the processes of crossover, variation and the like of chromosome genes in the similar biological evolution by a mathematical mode and by utilizing computer simulation operation. When a complex combined optimization problem is solved, a better optimization result can be obtained faster compared with some conventional optimization algorithms.

In the embodiment of the present disclosure, as described above, the smaller the size of the diffuse spot, the higher the quality of the image. Therefore, when the size of the diffuse spot of the acquired image is smaller than the size threshold, it can be determined that the quality of the image satisfies the preset condition. The size threshold may be a preset fixed value or a variable value dynamically set according to different images, and is not limited herein.

Or, when the position of each pixel is optimized, under the condition that the optimization is not performed, the quality of the image is determined to meet the preset condition. Specifically, the size of the diffuse spot of the last acquired image can be acquired, and when the difference value between the size of the diffuse spot of the last acquired image and the size of the diffuse spot of the currently acquired image is smaller than a preset threshold value, it is determined that the quality of the image meets a preset condition. The preset threshold may be 3 pixel units, 5 pixel units, etc., and is not limited herein.

For example, the size of the diffuse spot (e.g., the diameter of the diffuse spot) of the last acquired image is 150 pixel units, and the size of the diffuse spot of the current acquired image is 148 pixel units, which is smaller than the preset threshold (e.g., 3 pixel units). At this time, it may be determined that the quality of the currently acquired image satisfies the preset condition, and the loop process is ended.

Referring to fig. 6 and 7, a schematic diagram of a diffuse spot before and after a pixel location update is shown, respectively. In fig. 6, the intensity is still large at a position farther from the center position of the image, that is, the size of the diffuse spot is large, 270 pixel units. In fig. 7, the light intensity is mainly concentrated in the central region of the image, and the light intensity is smaller at a position farther from the central position of the image, that is, the size of the dispersed spot is smaller, and is 150 pixel units. It is found by comparison that the size of the diffuse spot is significantly reduced, and thus the influence of the display screen corresponding to fig. 7 on the imaging quality is smaller than the influence of the display screen corresponding to fig. 6 on the imaging quality.

It can be understood that, since the quality of the acquired image after the last position update can satisfy the preset condition, the position coordinates of each pixel after the last position update can be directly used as the final position coordinates of each pixel. Through the final pixel arrangement mode, the influence of the diffraction phenomenon on the imaging quality of the camera can be reduced.

In the embodiment of the present disclosure, since some restrictions are made on the position offset of each pixel, the display effect of the display screen may be less affected. Fig. 8 and 9 show a schematic diagram of a pixel position before and after a pixel position update, respectively, and it can be seen that, after the pixel position update, the display screen cannot obviously see the change of the pixel position, so that the influence on the display effect of the display screen can be ensured to be relatively small.

According to the pixel position determining method, the pixel position of the display screen is slightly updated, so that the influence of screen diffraction on image quality is reduced, and the imaging quality of the camera under the screen is improved. Meanwhile, the influence of the tiny position update of each pixel on the screen display effect is small. Therefore, the imaging quality of the camera under the screen and the display effect of the display screen can be considered simultaneously.

It should be noted that although the various steps of the methods of the present disclosure are depicted in the drawings in a particular order, this does not require or imply that these steps must be performed in this particular order, or that all of the depicted steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc.
