Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The image display method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The terminal 102 may include a display device, the terminal 102 may display a screen image on the display device, the terminal 102 may obtain the screen image from the server 104 through a network, or may generate the screen image locally at the terminal 102, the terminal 102 may display a current screen image frame corresponding to the screen image when the display device is in a screen display mode, and if the current screen image frame is not a last frame of all screen image frames, the terminal 102 may determine a plurality of outward-diffused second light-emitting pixel points corresponding to a next screen image frame according to a plurality of first light-emitting pixel points in the current screen image frame, and control the plurality of second light-emitting pixel points to emit light, and other pixel points do not emit light, thereby switching the current screen image frame in the display device to a next screen image frame. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by multiple servers.
In one embodiment, as shown in fig. 2, an image display method is provided, which is described by taking the method as an example applied to the terminal in fig. 1, and includes the following steps:
step S202, displaying a current screenshot image frame corresponding to the screenshot image when the display device is in the screenshot display mode; the screen-turning image corresponds to at least two screen-turning image frames.
The display device may be a device for displaying, which is disposed in the terminal 102, and the terminal 102 may include a screenshot display mode, for example, when the terminal 102 is idle or locked for a period of time, the terminal 102 may enter the screenshot display mode, and in this mode, the terminal 102 may display a specific screenshot image, which may be generated or acquired locally, or may be generated or acquired from the server 104. The screenshot image displayed by the terminal 102 in the screenshot display mode may include at least two screenshot image frames, and the screenshot image frame of each frame may have a different display effect. Specifically, the at least two osd image frames may be four osd image frames, including a start frame, a second frame, a third frame, and a last frame. It should be noted that the at least two image frames may not be limited to four frames, and may also be more than four image frames or less than four image frames. Each frame may display a different image in the display device. When entering the screen saver display mode for the first time, the terminal 102 may display the start frame first, and may also display other screen saver image frames corresponding to the start frame.
Step S204, if the current screenshot image frame does not belong to the last frame of the at least two screenshot image frames, determining a plurality of second light-emitting pixel points corresponding to the next screenshot image frame according to a plurality of first light-emitting pixel points in the current screenshot image frame; the plurality of second light-emitting pixel points are distributed in an outward diffusion mode relative to the plurality of first pixel points.
The screenshot image frame may include at least two screenshot image frames, for example, a start frame, a second frame, a third frame, and a last frame. It should be noted that the screenshot image frame may be other number of image frames than four frames. The terminal 102 may detect and determine a current screener image frame of the display device, specifically, the terminal 102 may determine whether the current screener image frame is a last frame of the at least two screener image frames, and if not, the terminal 102 may determine a plurality of second light-emitting pixel points corresponding to a next screener image frame according to a plurality of first light-emitting pixel points in the current screener image frame, for example, the terminal 102 may find, based on the plurality of first light-emitting pixel points in the current screener image frame, pixel point positions in the display device that may be light-emitting pixel points in the next screener image frame, thereby achieving a conversion effect from the current screener image frame to the next screener image frame. The plurality of second light-emitting pixel points are distributed in an outward diffusion manner relative to the plurality of first pixel points, for example, the second light-emitting pixel points can gradually diffuse frame by frame screen image frames, and the diffusion amplitude can be larger and larger. Specifically, the terminal 102 may select the corresponding second light-emitting pixel point in a specific area around each first light-emitting pixel point, and the terminal 102 may further adopt different transformation modes according to the positions of the current screenshot image frame in all screenshot image frames.
In addition, if the screenshot image frame corresponding to the screenshot image includes four frames, such as the start frame, the second frame, the third frame, and the last frame, the start frame, the second frame, the third frame, and the last frame may be four frames that are sequentially played in turn. The initial frame may be a line image frame, and in order to gradually diffuse the light-emitting pixels in each information frame, the light-emitting pixels in each information frame may be at least spaced by a preset number of pixels. For example, the light-emitting pixel points of the second frame are at least spaced by a first number of pixel points; the light-emitting pixel points of the third frame are at least spaced by a second number of pixel points; the last frame of luminous pixel points are at least spaced with a third number of pixel points; and, the quantity of first quantity pixel, second quantity pixel and third quantity pixel can increase in proper order. Specifically, the terminal 102 may set 3 pixels around the light-emitting pixel a' of the second frame to be transparent, that is, not to emit light, and form a distance D2 at least separating 3 pixels, that is, the first number of pixels; the terminal 102 may set 10 pixels around the light-emitting pixel a ″ of the third frame as non-light-emitting, forming a distance D2' that is at least 10 pixels apart, that is, the second number of pixels; the terminal 102 may set 20 pixels at the wheelbase of the light-emitting pixel a' "of the last frame to be non-light-emitting, and form a distance D2 ″ that is at least separated by 20 pixels, that is, the third number of pixels. Therefore, the corresponding distances of the D2, the D2' and the D2 ″ can be gradually increased, so that the information screen image is diffused frame by frame, and the light-emitting pixels are continuously reduced.
Step S206, controlling the plurality of second light-emitting pixel points to emit light, and controlling other pixel points not to emit light, so as to switch the current screenshot image frame of the display device to the next screenshot image frame.
The second light-emitting pixel points may be pixels emitting light in a next breath screen image frame, each second light-emitting pixel point may be determined according to a first light-emitting pixel point in a current breath screen image frame, and the first light-emitting pixel point may be a pixel emitting light in the current breath screen image frame. The terminal 102 may control the plurality of second light-emitting pixel points to emit light and make other pixel points not emit light after determining each second light-emitting pixel point in the next screenshot image frame, thereby implementing switching from the current screenshot image frame to the next screenshot image frame.
In the image display method, when the display device is in the screen displaying mode, the current screen image frame corresponding to at least two screen images is displayed, if the current screen image frame does not belong to the last frame of the at least two screen image frames, a plurality of second light-emitting pixel points which are distributed in an outward diffusion mode and correspond to the next screen image frame are determined according to a plurality of first light-emitting pixel points in the current screen image frame, the second light-emitting pixel points are controlled to emit light, and other pixel points do not emit light, so that the current screen image frame of the display device is switched to the next screen image frame. Compared with the traditional mode of displaying the information screen image by moving the whole display block, the scheme controls each pixel point of the display equipment in the information screen display mode, realizes diffusion display of the information screen image, and realizes the effect of effectively slowing down the aging of the screen pixel points.
In one embodiment, determining a plurality of second light-emitting pixel points corresponding to a next screenshot image frame according to a plurality of first light-emitting pixel points in the current screenshot image frame includes: selecting a plurality of spaced light-emitting pixel points from the light-emitting pixel points of the current information screen image frame as a plurality of first light-emitting pixel points; aiming at each first light-emitting pixel point, acquiring a non-light-emitting pixel point which is at least separated from the first light-emitting pixel point by a set distance to serve as a second light-emitting pixel point corresponding to the first light-emitting pixel point; and obtaining a plurality of second light-emitting pixel points according to the second light-emitting pixel points corresponding to the first light-emitting pixel points respectively.
In this embodiment, the terminal 102 may determine a plurality of second light-emitting pixel points corresponding to the next screenshot image frame according to a plurality of first light-emitting pixel points in the current screenshot image. The above-mentioned screenshot image frame may include at least two screenshot image frames, for example, there may be four frames including a start frame and a non-start frame. The terminal 102 may select a plurality of spaced light-emitting pixel points from the light-emitting pixel points of the current screenplay image frame as a plurality of first light-emitting pixel points, and the terminal 102 may determine different selection ranges according to whether the current screenplay image frame is a start frame or a non-start frame. Specifically, if the starting frame is the starting frame, since the starting frame is the line image, the terminal 102 may select the pixel points at the line edge from the line image as the first light-emitting pixel points, and may continue to select the remaining line edge pixel points after the processing of the currently selected pixel points at the line edge is completed, knowing that all the light-emitting pixel points in the line image are processed, thereby forming the non-line image. If the current raster image frame is a non-initial frame, the non-initial frame may be a non-linear image, and the terminal 102 may select a part of the light-emitting pixels from the current raster image frame as a plurality of first light-emitting pixels, specifically, the terminal 102 may select one of the random numbers among every n light-emitting pixels in the raster image frame of the non-initial frame as non-light-emitting pixels, for example, when the raster image frame is four frames, n of each frame may be gradually increased, specifically, the terminal 102 may select one of the random numbers as non-light-emitting pixels among every 20 light-emitting pixels in the light-emitting pixels of the second frame, and select one of the random numbers as non-light-emitting pixels among every 10 light-emitting pixels in the light-emitting pixels of the third frame as non-light-emitting pixels, and select one of the random numbers as non-light-emitting pixels among the light-emitting pixels of the last frame. Therefore, the rest luminous pixel points in each frame can be used as the plurality of first luminous pixel points.
After acquiring a plurality of first light-emitting pixel points of the current screenshot image frame, the terminal 102 may acquire, for each first light-emitting pixel point, a non-light-emitting pixel point at least spaced from the first light-emitting pixel point by a set distance, and use the non-light-emitting pixel point as a second light-emitting pixel point corresponding to the first light-emitting pixel point. The terminal 102 may determine different setting distances according to whether the current screenshot image frame is a start frame or a non-start frame. The terminal 102 may obtain the non-light-emitting pixel points from different regions and different distances according to different current screenshot image frames. The terminal 102 may obtain the corresponding second light-emitting pixel point for each first light-emitting pixel point in the above manner, so that the terminal 102 may obtain a plurality of second light-emitting pixel points according to the respective corresponding second light-emitting pixel points of the plurality of first light-emitting pixel points.
Through the embodiment, the terminal 102 can select a plurality of first light-emitting pixel points from the current information screen image frame and obtain the second light-emitting pixel points corresponding to the first light-emitting pixel points based on the set spacing distance, so that the light-emitting pixel points of the next information screen image frame can be determined, the information screen image can be dynamically displayed, and the aging of the screen pixel points can be effectively slowed down.
In one embodiment, if the current screenshot image frame is an initial frame, for each first light-emitting pixel, acquiring a non-light-emitting pixel spaced at least a set distance from the first light-emitting pixel as a second light-emitting pixel corresponding to the first light-emitting pixel, including: acquiring the carousel sequence of the next screenshot image frame in at least two screenshot image frames; acquiring a first distance corresponding to carousel sequencing; aiming at each first light-emitting pixel point, acquiring an adjacent first light-emitting pixel point closest to the first light-emitting pixel point, and acquiring a target direction vertical to the connecting line direction of the first light-emitting pixel point and the adjacent first light-emitting pixel point; and acquiring at least one non-luminous pixel point which is positioned in the target direction and is within a first distance from the first luminous pixel point as a second luminous pixel point.
In this embodiment, the above-mentioned screenshot image frame may include multiple frames, including a start frame and a non-start frame, and the terminal 102 may determine the second light-emitting pixel point in a specific manner when the current screenshot image frame is the start frame. The multiple information screen image frames may be sequentially carousel frames, and the terminal 102 may obtain a carousel sequence of a next information screen image frame in at least two information screen image frames, and obtain a first distance corresponding to the carousel sequence, where the first distance may be set according to an actual situation and may be represented by the number of pixels. The terminal 102 may obtain, for each first light-emitting pixel point, a neighboring first light-emitting pixel point closest to the first light-emitting pixel point, and obtain a target direction perpendicular to a connection direction of the first light-emitting pixel point and the neighboring first light-emitting pixel point, and the terminal 102 may obtain at least one non-light-emitting pixel point located in the target direction and within a first distance from the first light-emitting pixel point, as a second light-emitting pixel point corresponding to the first light-emitting pixel point. Specifically, as shown in fig. 3, fig. 3 is a schematic interface diagram of a start frame in an embodiment. As shown in fig. 4, fig. 4 is a schematic interface diagram of a second frame in an embodiment. When the current frame is the start frame, since the start frame is a line image, the terminal 102 may obtain the connection directions X1 and X2 of the light-emitting pixel A, C at the line edge and the nearest neighboring light-emitting pixel B, D; acquiring scattering directions Y1 and Y2 which are perpendicular to the connecting line direction, and scattering directions Y3 and Y4 which are perpendicular to the connecting line direction; the terminal 102 may at least separate the original first distance D1 of the light emitting pixel in the scattering directions Y1, Y2, the random number selects the light emitting pixel of the next frame as a ', C' in fig. 4, the terminal 102 may select the coloring light emitting pixel a 'of the next frame in the random number of 5 pixels D1 outside the light emitting pixel a of the initial frame, and the distance a' after the random selection from the original first light emitting pixel a is 3 pixels.
In addition, the terminal 102 may select one random number as non-light-emitting between the obtained light-emitting pixel points of the next frame and every n light-emitting pixel points, so as to form a diffusion effect, thereby obtaining a second light-emitting pixel point in the next screenshot image frame.
