Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Please refer to fig. 1, which is a panel sampling method of the present invention, including the following steps, S100 sets up a sampling mask block with a first sub-pixel on a panel as a center, S102 obtains preset displayed video data in the sampling mask block, eliminates an area of a position without the video data in the sampling mask block, samples video data at other positions, and S104 performs normalization processing on a sampling result to obtain a display result of the first sub-pixel. In principle, the feedback of color to the human eye is the average of multiple lights seen, and the brightness is the same as the color. Based on the principle, the display panel of the display plays an important role in visual presentation, and when the display panel receives content to be displayed (hereinafter referred to as video data), due to various innate reasons such as resolution and picture cutting, the display panel faithfully presents various disfigurements such as sharp edges and large color blocks, and the like, and displays results. According to the scheme, the sampling mask block is established, the area of the sampling mask block is larger than that of the sub-pixels, all video data in the area of the sampling mask block are subjected to normalization calculation, a reasonable display result is finally obtained, and the problem of poor edge position display effect can be effectively solved.
The method can also be applied to some panels with pixels arranged in matrix and rows and columns, and can also obtain better effect. In other specific embodiments, the method can achieve better effects, such as the panel schematic shown in fig. 2, in which the pixels are arranged in Delta, the right side of the panel schematic shows a partially enlarged view, and the enlarged view can see a second sub-pixel located at the center, the second sub-pixel is adjacent to six third sub-pixels with different colors, and the third sub-pixels with different colors are arranged above, below, above left, below left, above right, and below right of the second sub-pixel. The third sub-pixels are in a hexagonal arrangement structure and are also divided into two colors which are not adjacent to each other. The panel with Delta arrangement can obtain clearer display and higher resolution in application, but cannot be directly displayed in a one-to-one correspondence mode, a new sampling mode is particularly important, the sampling result of the area without video data in a sampling mask block is deleted, then the sampling results of other blocks are normalized, and coefficients in the sampling result are relative areas. The following is illustrated by some examples.
FIG. 3 shows a diagram of input video data, where r (i, j) represents the luminance of the red sub-pixels at the i-th row and the j-th row in the input video data, g (i, j) represents the luminance of the green sub-pixels at the i-th row and the j-th row in the input video data, and b (i, j) represents the luminance of the blue sub-pixels at the i-th row and the j-th row in the input video data. Fig. 4 is a schematic diagram of the actual arrangement of panel sub-pixels, where R (m, n) represents the luminance of the red sub-pixels actually displayed by the panel in the m-th row and the n-th column, G (m, n) represents the luminance of the green sub-pixels actually displayed by the panel in the m-th row and the n-th column, and B (m, n) represents the luminance of the blue sub-pixels actually displayed by the panel in the m-th row and the n-th column. Fig. 5 is a schematic diagram of a mask (sampling mask block), where the size of the mask is adjustable, and the display effect after sampling can be adjusted by adjusting the size of the mask.
In the embodiment shown in fig. 6, a method for calculating the SPR sampling formula by mask is shown, that is, a relationship between R (m, n)/G (m, n)/B (m, n) and R (i, j)/G (i, j)/B (i, j) is calculated according to the area of R (i, j)/G (i, j)/B (i, j) framed by mask.
For the derivation of the edge position sampling formula, taking the first sub-pixel R (1,1) as an example, as shown in fig. 7a and 7b, the influence of R (1,1) on the sampling of the input video data R (i, j) is shown in the case of masks with two shapes. In FIG. 7a, the length of the mask is 4 times the actual sub-pixel length of the panel, and the width of the mask is 2 times the sub-pixel width of the panel; in FIG. 7b, the mask length is 4 times the panel actual sub-pixel length, and the mask width is 3 times the panel sub-pixel width. Those skilled in the art will appreciate that the actual mask sizes that may be selected are not limited to two, 7a, 7 b.
As shown in FIG. 7a, from the area of mask-framed r (i, j)/g (i, j)/b (i, j), we can derive:
R(1,1)＝x*[1/2*r(1,0)+1/2*r(1,1)+1/2*r(1,2)+r(2,0)+r(2,1)+r(2,2)+1/2*r(3,0)+1/2*r(3,1)+1/2*r(3,2)]；
since video data r (1,0), r (2,0) and r (3,0) do not exist, taking the values of these three as 0 yields:
R(1,1)＝x*[1/2*r(1,1)+1/2*r(1,2)+r(2,1)+r(2,2)+1/2*r(3,1)+1/2*r(3,2)]；
the normalization process can result in the display result of the first sub-pixel R (1,1) in fig. 7 a) as follows:
R(1,1)＝1/8*r(1,1)+1/4*r(2,1)+1/8*r(3,1)+1/8*r(1,2)+1/4*r(2,2)+1/8*r(3,2)；
the same can be derived for the first subpixel R (1,1) in FIG. 7b as:
R(1,1)＝1/6*r(1,1)+1/6*r(2,1)+1/6*r(3,1)+1/6*r(1,2)+1/6*r(2,2)+1/6*r(3,2)。
in other embodiments, the implementing step includes the following processes:
the method comprises the following steps: obtaining a relation between R (m, n)/G (m, n)/B (m, n) and R (i, j)/G (i, j)/B (i, j) according to the area of R (i, j)/G (i, j)/B (i, j) framed by the mask;
step two: zero-finding the nonexistent video data of the mask frame during sampling to obtain a new relation between R (m, n)/G (m, n)/B (m, n) and R (i, j)/G (i, j)/B (i, j);
step three: and normalizing the coefficients before R (i, j)/G (i, j)/B (i, j) in the new relation between R (m, n)/G (m, n)/B (m, n) and R (i, j)/G (i, j)/B (i, j) to obtain the final sampling formula of R (m, n)/G (m, n)/B (m, n).
In other specific embodiments, the method further comprises the steps of determining whether the first pixel is located at an edge of the panel; if yes, step S100 is performed to establish a sampling mask block with the first sub-pixel on the panel as the center. The method for judging whether the edge is the edge comprises the steps of distance, pixel number and the like, for example, the preset edge thickness is a distance with a plurality of pixel numbers or equal length, for example, 1-4 sub-pixels, and the steps of establishing a mask to obtain a normalized display result and the like are only carried out when the sub-pixels in the range are used for displaying and sampling, but not the sub-pixels in the range, which is not applicable to the sampling method of the scheme of the invention. Through the optimization, the display effect of the edge pixel of the scheme of the invention is further improved.
The invention also introduces a panel sampling storage medium which stores a computer program, wherein the computer program executes the following steps when being operated, the computer program takes a first sub-pixel on a panel as a center, establishes a sampling mask block, acquires preset display video information in the sampling mask block, eliminates the area of the position without the video information in the sampling mask block, samples the video information at other positions, and performs normalization processing on the sampling result to obtain the display result of the first sub-pixel.
Specifically, the panel is a Delta-arrangement panel, and specifically includes a second sub-pixel, the second sub-pixel is adjacent to six third sub-pixels with different colors, and the third sub-pixels with different colors are arranged above, below, above-left, below-left, above-right, and below-right of the second sub-pixel.
Further, the computer program when executed further performs the step of determining whether the first pixel is located at an edge of the panel; if yes, the step is carried out, and a sampling mask block is established by taking the first sub-pixel on the panel as the center.
A panel sampling computer, the computer comprising the storage medium described above.
