As shown in fig. 1, in one embodiment, a display control method of a transparent display screen is provided, which specifically includes the following steps:
s101, determining all pixels in a color development state, and determining edge pixels in all pixels in the color development state;
s102, regarding each edge pixel, taking the edge pixel as a center to make a ray, recording the distance of the edge of the pixel or the screen in the first color development state, which the ray passes, rotating the ray within the range of 0-360 degrees, and recording the distance S of the edge of the pixel or the screen in the first color development state, which the ray passes every time when rotating by one angle;

In the present embodiment, the pixel in the color development state refers to a pixel with a color, including a white pixel, and the pixel in the transparent state is the opposite.
In this embodiment, the edge pixel refers to an edge pixel of the display image, and not an edge pixel of the whole image, for example, a transparent region is in the middle of the image, and then a pixel where the image borders the transparent region is also an edge pixel.
In this embodiment, the start point of the ray is the center point of the edge pixel, the distance of the pixel of the first color development state through which the ray passes is the distance from the center point of the edge pixel to the center point of the pixel of the first color development state, and the distance of the screen edge through which the ray passes is the distance from the center point of the edge pixel to the center point of the pixel of the screen edge.
In this embodiment, the angle of rotation is an angle at which the ray passes through the center point of the pixel of the first color development state or the pixel of the screen edge every time the ray rotates, and the value of the angle is not a fixed value.
In the present embodiment, the distance maximum value of each edge pixel is the maximum value among all s of each pixel.
In this embodiment, the distance average value of each edge pixel is a value obtained by adding all s of each pixel and dividing the sum by the number of s.
In this embodiment, the purpose of adjusting the color value of the pixel is to enhance the color effect of the pixel, the display creates colors through the RGB color module, each color in the RGB color module ranges from 0 to 255, the smaller the value is representing the darker the color, the color effect of the enhanced pixel is essentially to reduce the color value of the pixel, so the adjustment coefficient acts to reduce the color value, and thus the adjustment coefficient is a coefficient smaller than 1.
In this embodiment, the adjustment area is an area formed by the pixels whose color values need to be adjusted, and if only the color values of the edge pixels are adjusted, color mutation may occur at the edge of the image, so that the color values of the pixels adjacent to the edge pixels need to be adjusted.
In this embodiment, adjusting the color values of the edge pixels and the pixels in the adjustment area reduces the color values of the edge pixels and the pixels in the adjustment area, deepens the color of the edge pixels and the pixels in the adjustment area, and makes the edge area and the transparent area have a contrast ratio visually, so that the edge of the image becomes clear.
According to the display control method of the transparent display screen, provided by the embodiment of the invention, the edge pixels are identified, the adjustment coefficients of the edge pixels are calculated, and the display color values of the edge pixels and the pixels in the adjustment range are adjusted according to the adjustment coefficients, so that the display effect of an image is enhanced, and particularly the display effect of the edge region of the image is enhanced, and the edge of the image becomes clear.
In one embodiment, the determining the edge pixels among the pixels in all the color development states includes:
s201, selecting a pixel in a color development state, and setting a grid of 3*3 by taking the pixel in the color development state as the center;
s202, judging whether pixels in the grids are in a color development state or not, if so, the selected pixels are not edge pixels, and if not, the selected pixels are edge pixels;
s203, executing S201-S202 on all the pixels in the color development state, and determining all the edge pixels.
In this embodiment, the grid of 3*3 is a 9-grid of 9 pixels in 3 rows and 3 columns.
In this embodiment, if the image is excessively large, the region including the edge pixels may be judged first using a lattice of 5*5 or more, and then the region including the edge pixels may be judged using a lattice of 3*3.
In this embodiment, the essence of the edge pixels is that pixels in a transparent state exist in pixels surrounding one circle of any one of the color development pixels, and the grid of 3*3 includes the center pixel and pixels surrounding one circle of the center pixel, so the judgment is performed using the grid of 3*3.
In one embodiment, the calculating the adjustment coefficient of each edge pixel according to the distance maximum value and the distance average value of each edge pixel includes:
determining an adjustment coefficient of each edge pixel by a X R/L+b X L/X;
where a and b are preset ratios, the sum of a and b is equal to 1, r is the distance average of the edge pixels, L is the distance maximum of the edge pixels, and X is the length, width, or diagonal length of the screen.
In this embodiment, the blurring of the edge pixel is caused by the influence of the light transmission amount of the transparent area on the edge pixel, and the pixel in the edge area is also the pixel in the edge area, and the influence of the transmitted light amount on the display color value of the pixel is naturally different due to the difference of the sizes of the transparent areas in different positions, for example, if a certain edge pixel is located at the edge of a small transparent area, the influence of the light amount transmitted through the transparent area on the color value of the pixel is small, the amplitude to be adjusted is small, if the edge pixel is located at the edge of a large transparent area, the influence of the light amount transmitted through the transparent area on the color value of the pixel is large, and the amplitude to be adjusted is large, so the calculated value is the adjustment coefficient of the edge pixel through calculating the influence of the light transmission areas with different sizes in different positions by a×r/l+b×l/X.
In the present embodiment, for X, the screen size having the smallest direction flat angle with respect to the maximum value of the distance from the edge pixel is first selected as the value of X, that is, the length or width of the screen, L must be smaller than X because the adjustment coefficient is smaller than 1, and if X is selected as the length or width of the screen and X is smaller than L, the length of the diagonal line of the screen is newly selected as the value of X.
In one embodiment, the determining the adjustment area by the edge pixel and the distance average value corresponding to the edge pixel includes:
for any one edge pixel, taking the edge pixel as a center, and taking the average value of the distance of the pixel as a radius to make a circle;
selecting pixels in a color development state covered by at least m circles, and forming an adjustment area by all the pixels in the selected display state;
wherein m is a preset value.
In this embodiment, the adjustment area may include edge pixels in the process of determining the adjustment area, and the edge pixels are removed when the adjustment area is formed.
In this embodiment, the larger the value of m, the smaller the adjustment area, for example, when m is equal to 2, the adjustment area is an area where two circles intersect, and when m is equal to 3, the adjustment area is an area where three circles intersect, and the area where three circles intersect falls within the area where two circles intersect.
In one embodiment, the adjusting the display color value of each edge pixel according to the adjustment coefficient of the corresponding edge pixel includes:
acquiring the color value of each edge pixel;
for each edge pixel, obtaining a display color value after the adjustment of the edge pixel by C (1-K);
wherein, C is the display color value before the edge pixel adjustment, and K is the adjustment coefficient of the edge pixel.
In this embodiment, the nature of C (1-K) is C-C, i.e., the display color value before edge pixel adjustment minus the display color value to be adjusted.
In this embodiment, the color value of the pixel is formed by an RGB color module, and adjusting the display color value refers to adjusting the RGB values respectively, for example, C is (80, 100, 60), K is 0.1, and then the adjusted display color value is (72, 90, 54).
In one embodiment, the adjusting the display color value of the corresponding pixel in the adjustment area according to the average value of the distance between the edge pixels and the adjustment coefficient includes:
acquiring a color value of each pixel of the adjustment area;
for each pixel of the adjustment area, obtaining a display color value after pixel adjustment by c-c (1-d/r);
wherein, for each pixel of the adjustment area, c is the display color value before the pixel adjustment, k is the adjustment coefficient of the edge pixel closest to the pixel, d is the distance between the pixel and the edge pixel closest to the pixel, and r is the average value of the distances between the pixel and the edge pixel closest to the pixel.
In this embodiment, C-C (1-d/r) is also C-C (K), where K is an adjustment coefficient of a pixel of the adjustment area and is equal to K (1-d/r), and since for any one edge pixel, the edge pixel is centered on the average value of the distance of the pixel and is rounded with a radius, the distance from the pixel in the adjustment area to the edge pixel is smaller than the average value of the distance of the edge pixel, i.e., d is smaller than r, so d/r is smaller than 1, K is smaller than K, and the display color value of the pixel adjustment of the adjustment area is smaller than the display color value of the edge pixel adjustment.
In one embodiment, the display control method of the transparent display screen further includes:
in the continuous playing process, comparing each pixel of adjacent frames to obtain difference pixels and the number of the difference pixels;
the ratio of the number of the difference pixels to the number of the total pixels is recorded as a difference value;
and judging whether the difference value is smaller than a first preset value, if so, executing S101-S107 on the difference pixels, and if so, executing S101-S107 on the whole image.
In this embodiment, comparing each pixel refers to whether the RGB values of the pixel in two adjacent frames are the same for the same pixel, if so, the pixel is not a difference pixel, and if not, the pixel is a difference pixel.
In this embodiment, if the difference value of the adjacent frames is small, the image representing the adjacent frames has only small change, if the whole image is debugged, the same adjustment coefficient is still obtained for the non-difference pixels, and the adjusted display color value is unchanged, so that if the difference value is smaller than the first preset value, only the difference pixel needs to be adjusted to the display color value.
In this embodiment, the first preset value represents the maximum value of the difference between two adjacent images, and therefore cannot be too large, typically being set to 10%.
In one embodiment, the display control method of the transparent display screen further includes:
if the difference values of the n continuous frames of images are smaller than the first preset value, judging whether n is larger than the second preset value, and if so, executing S101-S107 on the whole image.
In this embodiment, only the difference value of the adjacent frames is determined during the continuous playing process, and for the first frame image and the nth frame image, the difference value may be larger than the first preset value, so that the display color value of the image needs to be adjusted again every second preset value frame number.
