Abstract: In one embodiment, a computing system may determine a group of subpixels, that are associated with different color channels, within a display region of a display. The system may determine a micro-pixel corresponding to a basic unit shape configured to evenly divide the display region and each subpixel. The system may represent the display region as a group of micro-pixels and each subpixel as a combination of one or more micro-pixels in the group of micro-pixels. The system may determine a constraint for each color channel of the display region based on the group of micro-pixels. The constraint may constrain the micro-pixels associated with a same subpixel to have a same color value. The system may generate, based on an optimization process using the constraint, a filter for the display region. The filter may be configured to adjust image pixel values to be displayed by the group of subpixels.

Abstract: In one embodiment, a computing system may receive a target image to be displayed on a display. The target image may have a first number of bits per color. The system may access a mask for each color channel of RGB color channels. The accessed masks may be generated based on (1) one or more characteristics of a human visual system, and (2) a subpixel geometry layout of the display. The system may generate an output image based on the target image and the accessed masks. The output image may have a second number of bits per color smaller than the first number of bits per color. The system may display the output image on the display for representing the target image.

Abstract: In one embodiment, a computing system may receive an image to be displayed on a display. The image may be associated with an input gamut and the display may be associated with an output gamut. The system may access a look-up-table that maps input colors to output colors. The output color of corresponding to each input color may be determined by adjusting a lightness of the input color according to a pre-determined tone curve while keeping the hue and chroma constant and (2) mapping the chroma to the output gamut of the display. The system may determine a final color for each pixel of the pixels of the image based on the look-up-table and an original color of that pixel. The system may display the final colors of the pixels on the display to represent the original colors of the image.
