The present application provides a multi-primary additive color mixing method and apparatus, a system, and a computer device. The method comprises: acquiring chromaticity coordinates and luminance of four additively mixed colors; determining four corresponding determination regions according to the chromaticity coordinates of any three of the four additively mixed colors; acquiring a target chromaticity coordinate and target luminance of target colored light; determining a target determination area in which the target chromaticity coordinate of the target colored light falls, the target determination area being one of the four determination areas; and according to chromaticity coordinates and luminance of three vertices of the target determination area and the target chromaticity coordinate and the target luminance of the target colored light, determining a light mixing ratio of the colors required to form the target colored light. The present application provides a brand-new multi-primary color mixing algorithm, which cross-partitions a color gamut range defined by four primary colors to obtain four determination regions formed on the basis of any three of four additively mixed colors, and computes a light mixing ratio of the four colors by determining a determination region in which target colored light falls, so as to complete mixing on the basis of the light mixing ratio and thereby control output of the target colored light.

This disclosure belongs to the field of image display, and specifically relates to an image display method, system, and apparatus. The image display method includes acquiring first color values ​​of predetermined pixels in a presented image. The first color values ​​include attribute values ​​of each primary color based on additive color mixing, wherein each primary color includes at least a first primary color and a second primary color, and the wavelength of the first primary color is at least 50 nm greater than the wavelength of the second primary color. The method also involves adjusting the attribute values ​​of each primary color in the first color values ​​according to an intensity adjustment ratio to obtain second color values ​​for presentation. The difference between the attribute values ​​of the first and second primary colors in the second color values ​​is greater than the difference between the attribute values ​​of the first and second primary colors in the first color values. By presenting the image, axial chromatic aberration is created to generate myopic defocus, thereby suppressing axial elongation of the eye.
