Abstract: A method includes receiving information about a color blindness of a viewer and an electronic display; receiving information about an input image including input R, G, and B values for pixels composing the input image; transforming each pixel's input values to corresponding x and y values in a CIE color space; identifying which of the pixels are within a filter area in the CIE color space; adjusting a color of the pixels that are within the filter area away from a confusion line for the color blind person to provide a corresponding color-modified pixel; generating a color-modified image composed of the color-modified and original pixels; and displaying the color-modified image with the electronic display.

Abstract: The invention features a system, including a graphics processing unit (GPU) and a memory storing instructions that when executed cause the GPU to: (i) receive, by a fragment shader executed on the GPU, rasterized data of a fragment of an image frame; (ii) determine, by the fragment shader executed on the GPU, an initial color for each pixel of the fragment; (iii) compute, by the fragment shader executed on the GPU, a relative level of stimulation of cones in a viewer's eye for each pixel of the fragment; (iv) compute, by the fragment shader executed on the GPU, a myopia-corrected color for each pixel of the fragment having a relative level of stimulation exceeding a threshold level, and (v) output, from the fragment shader executed on the GPU, the myopia-corrected pixel data for the fragment.

Abstract: A method and an apparatus for modifying initial image data for a frame based on a relative level of stimulation of cones in a viewer's eye are disclosed, wherein the modified image data results in reduced contrast between neighboring cones in the viewer's eye.
