The image information of the initial image may include pixel information of each initial sub-pixel, and the pixel information may include information of gray scale or color value, which will be described later. Similarly, the target pixel can be regarded as being formed by stitching a plurality of target sub-pixels.
In the embodiment of the present invention, a plurality of target pixel units in a target image are in one-to-one correspondence with a plurality of initial pixel units in an initial image, and therefore, the plurality of target pixel units in the target image are in one-to-one correspondence with a plurality of pixels in a display substrate, and for each target pixel unit, the target pixel unit may include three target sub-pixels, and the arrangement manner of the colors of the target sub-pixels in the target pixel unit is the same as the arrangement manner of the colors of the sub-pixels of the pixels in the display substrate corresponding thereto, for example, when the arrangement manner of the colors of the sub-pixels of the pixels in the display substrate is red, green, and blue, the arrangement manner of the colors of the three target sub-pixels in the target pixel unit is red, green, and blue.

Fig. 4 is a schematic diagram of a row of initial pixel units according to an embodiment of the present invention, as shown in fig. 4, specifically, a stripe pixel group may refer to: for any two adjacent initial pixel units in the group, one of the color types is of a first type and the other of the color types is of a second type, i.e. the plurality of initial pixel units in the group are continuous black and white stripes. In the embodiment of the present invention, since in step S3, the first color type (black) is marked as label=0 and the second color type (white) is marked as label=1, when determining whether the first and second sets of initial pixel units are stripe pixel groups, it may be determined whether the set of initial pixel units are stripe pixel groups according to the accumulated sum of the Label values of the plurality of initial pixel units in the set of initial pixel units and the Label value of the initial pixel unit a of the color type to be confirmed. Referring to formula (6), taking an example that the first and second groups of initial pixel units each include 9 initial pixel units, when the sum of the Label value of the group of initial pixel units located at the left side and the Label value of the initial pixel unit a of the color type to be confirmed is 341, the arrangement mode of the Label value of the group of initial pixel units and the Label value of the initial pixel unit a of the color type to be confirmed is 0101010101, that is, the color type of the ith row of j-9 initial pixel units is black, the color type of the ith row of j-8 initial pixel units is white, the color type of the ith row of j-7 initial pixel units is black, the color type of the ith row of j-6 initial pixel units is white, and so on. Thus, the set of initial pixel cells can be determined as a continuous black and white stripe, i.e., a striped pixel set. When the sum of the Label values of the group of initial pixel units located at the left side and the Label value of the initial pixel unit A of the color type to be confirmed is 682, the arrangement mode of the Label values of the group of initial pixel units and the Label values of the initial pixel unit A of the color type to be confirmed is 1010101010, namely, the color type of the j-9 th initial pixel unit of the i-th row is white, the color type of the j-8 th initial pixel unit of the i-th row is black, the color type of the j-7 th initial pixel unit of the i-th row is white, the color type of the j-6 th initial pixel unit of the i-th row is black, and so on. Thus, the set of initial pixel cells may also be determined to be a continuous black and white stripe, i.e., a striped pixel set. Similarly, when the sum of the Label values of the set of initial pixel units located on the right side and the Label value of the initial pixel unit a of the color type to be confirmed is 341, the arrangement manner of the Label values of the set of initial pixel units and the Label values of the initial pixel unit a of the color type to be confirmed is "0101010101", and when the sum of the Label values of the set of initial pixel units located on the right side and the Label values of the initial pixel unit a of the color type to be confirmed is 682, the arrangement manner of the Label values of the set of initial pixel units and the Label values of the initial pixel unit a of the color type to be confirmed is "1010101010", which is not described herein.
It should be noted that, if the initial pixel unit a of the color type to be confirmed is at the edge of the initial image, the number of the plurality of initial pixel units on one side thereof may be less than 9, and at this time, the color types of the missing initial pixel units are complemented with Label=0. Of course, the number of the initial pixel units in each group in the above embodiment is merely illustrative, and specific values thereof may be determined according to actual needs and are not limited herein.
