Disclosed are an image compression method and apparatus, and an intelligent terminal and a computer-readable storage medium. The method comprises: obtaining a target image, and determining reference pixel points corresponding to target pixel points; determining pixel difference values of the target pixel points and the reference pixel points corresponding to same; determining, according to the pixel difference values, point compression data corresponding to the target pixel points; and compressing the target pixel points according to the point compression data to obtain image compression data of the target image.

Image compression method and apparatus, and intelligent terminal and computer-readable storage medium

The present application provides a chrominance visual angle correction method for a display, and an intelligent terminal and a storage medium. The method comprises: acquiring brightness data of different primary colors varying with the gray scale at a vertical visual angle and a squint visual angle, and generating a search database; splitting, according to the search database and a preset rule, a pixel gray scale of the display into a plurality of high and low gray scale combinations composed of high gray scales and low gray scales; calculating a scale of brightness of the plurality of high and low gray scale combinations, and acquiring a scale of brightness of high and low gray scale combination closest to a scale of vertical vision brightness as a primary color pixel gray scale.

Chrominance visual angle correction method for display, and intelligent terminal and storage medium

Disclosed in the present application are a color gamut mapping method, a color gamut mapping assembly, and a display device. The method includes: obtaining a first connection line between a white point and an original point of the original color gamut; obtaining a first mapping point in a target color gamut of an intersection point of the first connection line and the original color gamut; obtaining a second connection line between a reference point in the original color gamut and the first mapping point; obtaining color coordinates of a second mapping point of the original point in the target color gamut; obtaining a luminance value of the second mapping point according to the original point and the white point; and obtaining grayscale values of the second mapping point according to the color coordinates and the luminance value of the second mapping point.

Color gamut mapping method, color gamut mapping assembly, and display device

The disclosure provides a method, device, and readable storage medium for adjusting image quality. The display device system selects a focus area of a target image, and outputs a mapping relationship curve of an input luminance value and an output luminance value of the target image. Then, an input luminance value range of pixels in the focus area of the target image is calculated, and upper and lower edge coefficients of the input luminance value range are proportionally adjusted to obtain new upper and lower edge coefficients. The mapping relationship curve is adjusted according to the new upper and lower edge coefficients, thereby adjusting the focus area of the target image.
