Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
Referring to fig. 1, fig. 1 illustrates a method for rendering sub-pixels in an image according to an embodiment of the present application, where the method may be applied to a server, and the server may be a physical server or a cloud server that provides various cloud services.
The number of servers is not limited in this application, and the servers may be independent servers, or may be a server cluster formed by a plurality of servers, or the like.
As shown in fig. 1, the method at least includes steps S110 to S140, and is described in detail as follows:
in step S110, a first image is acquired, where the first image includes a plurality of first pixel points, and each of the first pixel points includes three basic sub-pixels.
The first image may be an image adopting a common sub-pixel arrangement mode, and the first image may include a plurality of pixel points (i.e., first pixel points) arranged in a matrix manner. Each first pixel point may include three colors of base sub-pixels corresponding to red, green and blue.
In one example, the server may obtain the first image from a local storage space; in another example, the server may also obtain the first image from a cloud or third party storage space. Those skilled in the art may implement the corresponding acquisition mode according to actual implementation needs, which is not limited in this application.
In step S120, the first image is converted into a second image, where the second image includes a plurality of second pixel points corresponding to the first pixel points, and each of the second pixel points includes two sub-pixels to be rendered.
Wherein the second image may be an image employing a particular subpixel arrangement. The second image may include a plurality of second pixel points corresponding to the first pixel points respectively, and the second pixel points include only two sub-pixels, for example, may include red and green, or green and blue, or blue and red. And the luminance value of the two sub-pixels (i.e., the sub-pixels to be rendered) is determined based on the luminance value of the base pixel of the same color of the first pixel point corresponding to the second pixel point.
In an exemplary embodiment of the present application, a person skilled in the art may preset a pixel conversion rule, and after acquiring the first image, the server may convert the first image into the second image according to the pixel conversion rule. The second image may include a plurality of second pixel points, where positions of the second pixel points are corresponding to the first pixel points in the first image, respectively. For example, the first pixel points are arranged in a matrix form, the second pixel points are also arranged in a matrix form, and the second pixel points are respectively in one-to-one correspondence with the first pixel points.
In an exemplary embodiment of the present application, two sub-pixels to be rendered in the second pixel point may be disposed in an interleaved manner, and specifically, two sub-pixels to be rendered in the same second pixel point may be disposed in an diagonally opposite manner in the second pixel point. In addition, the color of the missing sub-pixel in the adjacent three second pixel points is different, for example, the first second pixel point adjacent to the missing sub-pixel of blue, the second pixel point missing the sub-pixel of red, the third second pixel point missing the sub-pixel of green, etc.
In an example, the sub-pixels to be rendered included in the second pixel point in the second image may be circularly arranged in the order of RG, GB, and BR. Thereby, the same color subpixels in the second image may be arranged obliquely downward. Compared with other arrangement modes, the arrangement mode of the sub-pixels in the oblique downward direction can ensure that the intervals among the sub-pixels are not too large, further ensure the resolution ratio during screen display and ensure the display effect of images.
Referring to fig. 1, in step S130, according to the luminance values of the base sub-pixels of the same color as the sub-pixels to be rendered of the second pixel point included in the target first pixel point, the luminance values of the sub-pixels to be rendered of the second pixel point are determined, where the target first pixel point includes at least two different rows and columns of first pixel points located in a predetermined range of the first pixel point corresponding to the second pixel point.
The target first pixel point may be a first pixel point used to determine a luminance value of a sub-pixel to be rendered of a second pixel point corresponding to the target first pixel point. In an example, the target first pixel point may include at least two different rows and columns of first pixel points within a predetermined range of the first pixel point corresponding to the second pixel point. It should be noted that the predetermined range may be a selection range preset by a person skilled in the art, for example, the predetermined range may be a selection range within one pixel adjacent to the first pixel corresponding to the second pixel, for example, the target first pixel may include the first pixel corresponding to the second pixel, and the first pixel located at the upper right of the first pixel, and so on.
It should be understood that the target pixel point includes first pixel points in different rows and columns, so that the determined brightness value of the sub-pixel to be rendered of the second pixel point includes the characteristic of the brightness value of the base sub-pixel with the same color of the first pixel points in different rows and columns, thereby effectively avoiding the occurrence of the conditions of line breakage or color edges and the like and further ensuring the display effect of the second image.
It should be noted that, the first pixel points of different rows and columns in the present application may be first pixel points of different rows, first pixel points of different columns, and first pixel points of different rows and columns, and a determination manner of a corresponding target first pixel point may be selected by a person skilled in the art according to actual implementation needs, which is not particularly limited in the present application.
In an exemplary embodiment of the present application, the server may determine the luminance value of the sub-pixel to be rendered in the second pixel point according to the luminance value of the base sub-pixel of the same color as the sub-pixel to be rendered of the corresponding second pixel point included in the target first pixel point. For example, if the second pixel point includes a red sub-pixel to be rendered, the luminance value of the red sub-pixel to be rendered in the second pixel point may be determined according to the luminance value of the red basic sub-pixel in the corresponding target first pixel point, and so on.
In an exemplary embodiment of the present application, the target first pixel includes a first pixel corresponding to the second pixel and another first pixel located at an upper right corner thereof, that is, the target first pixel includes two first pixels, one is a first pixel corresponding to the second pixel, and the other is a first pixel located at an upper right corner of the first pixel. Therefore, the target first pixel point comprises two oblique first pixel points, and the brightness value of the sub-pixel to be rendered of the second pixel point determined based on the brightness values of the basic sub-pixels of the two first pixel points can comprise the brightness characteristics of the two first pixel points, so that the occurrence of the condition of broken lines or colored edges can be avoided.
Based on the foregoing embodiment, the target first pixel point may further include a first pixel point located above and to the right of the first pixel point corresponding to the second pixel point. That is, the target first pixel point may include first pixel points corresponding to the second pixel point, and three first pixel points located at an upper, upper right corner and a right side of the first pixel point, for a total of four first pixel points. The brightness value of the sub-pixel to be rendered in the second pixel points determined based on the four first pixel points in the target first pixel points can avoid the occurrence of uneven line thickness, and meanwhile, the occurrence of line breakage can be further reduced, so that the display effect of the second image is ensured.
In step S140, the second image is displayed according to the determined brightness value of the sub-pixel to be rendered of each second pixel point.
In this embodiment, after determining the luminance value of the sub-pixel to be rendered in each second pixel point, the server may display the second image on the screen based on the luminance value, thereby determining the luminance value of the sub-pixel to be rendered of the corresponding second pixel point according to the luminance values of the base pixels included in the first pixel points of different rows and columns, so as to avoid the occurrence of line break and color edge conditions, and ensure the display effect of the image. In addition, the sub-pixels to be rendered of the second pixel points in the second image are arranged in a staggered mode, so that the size of the interval between the sub-pixels to be rendered can be ensured, the excessive interval between the sub-pixels to be rendered is avoided, and the resolution ratio during screen display can be improved.
Based on the embodiment shown in fig. 1, in an exemplary embodiment of the present application, determining, according to a luminance value of a base subpixel of the same color as a subpixel to be rendered of the second pixel included in a target first pixel, a luminance value of each subpixel to be rendered in the second pixel includes:
and carrying out weighted sum operation according to the brightness value of the basic sub-pixel with the same color as the sub-pixel to be rendered of the second pixel point contained in the target first pixel point, so as to obtain the brightness value of each sub-pixel to be rendered in the second pixel point.
In this embodiment, the server may perform a weighted sum operation based on the luminance values of the base sub-pixels of the same color as the sub-pixels to be rendered of the second pixel point included in the target first pixel point, so as to determine the luminance value of each sub-pixel to be rendered in the second pixel point. Specifically, the server may obtain, in advance, a weight value of a base subpixel included in each target first subpixel point, and perform a weighted sum operation based on a luminance value of the base subpixel and the weight value, so as to determine a luminance value of a subpixel to be rendered.
Referring to fig. 2, fig. 2 is a schematic diagram of calculation for determining a luminance value of a sub-pixel to be rendered according to an embodiment of the present application (taking the example that the target first pixel point includes a first pixel point corresponding to the second pixel point and a first pixel point located at an upper right corner thereof as an example).
As shown in fig. 2, the display schematic diagram of the first pixel point in the first image is located at the upper side, and the display schematic diagram of the second pixel point in the second image is located at the lower side. Based on the rendering method provided in the application, if the luminance value of the blue sub-pixel to be rendered included in the second pixel point located in the i-th row and the 1 st column in the second image is to be determined, the determination may be based on the luminance value of the blue base pixel value of the first pixel point corresponding to the second pixel point (i.e., the first pixel point located in the i-th row and the 1 st column in the first image) and the first pixel point located in the upper right corner of the first pixel point (i.e., the first pixel point located in the i-1 st row and the 2 nd column in the first image).
Specifically, the calculation may be performed with reference to the following formula:
B (i,1) ＝k 1 *Bb (i,1) +k 2 *Bb (i-1,2)
wherein k is 1 And k 2 Is the corresponding weight value, and k 1 +k 2 ＝1。
Fig. 3 shows a schematic calculation diagram for determining a luminance value of a sub-pixel to be rendered according to another embodiment of the present application (taking the example that the target first pixel point includes a first pixel point corresponding to the second pixel point and first pixel points located above, in the upper right corner and in the right side thereof as an example).
Referring to fig. 3, the top is a display schematic diagram of a first pixel in the first image, and the bottom is a display schematic diagram of a second pixel in the second image. Based on the rendering method provided in the application, if the luminance value of the red sub-pixel to be rendered included in the second pixel point located in the i-th row and the 2 nd column in the second image is to be determined, the luminance value of the red basic sub-pixel in the first pixel point corresponding to the second pixel point (i.e., the i-th row and the 2 nd column in the first image) and the first pixel point located above the first pixel point (i.e., the i-1 th row and the 2 nd column in the first image), the first pixel point located in the upper right corner of the first pixel point (i.e., the i-1 th row and the 3 rd column in the first image) and the first pixel point located on the right side of the first pixel point (i.e., the i-th row and the 3 rd column in the first image) may be determined.
Specifically, the calculation may be performed with reference to the following formula:
R (i,1) ＝k 1 *Rr (i-1,2) +k 2 *Rr (i-1,3) +k 3 *Rr (i,2) +k 4 *Rr (i,3)
wherein k is 1 、k 2 、k 3 、k 4 Is the corresponding weight value, and k 1 +k 2 +k 3 +k 4 ＝1。
In an exemplary embodiment of the present application, in the target first pixel point, a weight value of a luminance value of a base sub-pixel of the first pixel point corresponding to the second pixel point is greater than a weight value of luminance values of base sub-pixels of other first pixel points. Therefore, the calculated brightness value of the sub-pixel to be rendered of the second pixel point can better store the brightness characteristics of the same-color basic sub-pixel of the first pixel point corresponding to the calculated brightness value, and the display effect of the second image is ensured.
Based on the embodiment shown in fig. 1, in an exemplary embodiment of the present application, the acquiring the first image includes:
acquiring gray-scale data corresponding to each first pixel point in a first image;
and converting the gray-scale data corresponding to each first pixel point into brightness data.
Therefore, the gray-scale data are converted into the corresponding brightness data, so that the subsequent rendering process can be facilitated, and the accuracy of subsequent display is further ensured.
In addition, the displaying the second image according to the determined brightness value of the sub-pixel to be rendered of each second pixel point includes:
and converting the determined brightness value of the sub-pixel to be rendered of each second pixel point into corresponding gray scale data so as to display the second image.
In this embodiment, after the brightness value of the sub-pixel to be rendered of the second pixel point is obtained by calculation, the brightness value is converted into corresponding gray-scale data, so that the display effect of the second image can be ensured to correspond to the display effect of the first image.
