Methods for color-blindness remediation through image color correction

A computer readable medium containing program instructions for displaying a color-modified image with an electronic display, wherein execution of the program instructions by one or more processors of a computer system causes the one or more processors to carry out the steps of:

• (a) receiving information about a color blindness of a viewer of an electronic display;
• (b) receiving information about an input image comprising input R, G, and B values for each of a plurality of pixels composing the input image;
• (c) transforming each pixel's input R, G, and B values to a corresponding x value and a corresponding y value, the x and y values being in a CIE color space;
• (d) identifying which of the pixels are within a filter area in the CIE color spaced based on the x, y values;
• (e) adjusting a color of each of the pixels that are within the filter area away from a confusion line in the CIE space for the color blind person to provide a corresponding color-modified pixel;
• (f) generating a color-modified image composed of the color-modified pixels and original pixels, the original pixels corresponding to pixels having the input R, G, and B values located outside the filter area in the CIE color space;
• and
• (g) displaying the color-modified image with the electronic display.

A system, comprising:

• an electronic display;
• and
• a data processing apparatus programmed to:
• (a) receive information about a color blindness of a viewer of the electronic display;
• (b) receive information about an input image comprising input R, G, and B values for each of a plurality of pixels composing the input image;
• (c) transform each pixel's input R, G, and B values to a corresponding x value and a corresponding y value, the x and y values being in a CIE color space;
• (d) identify which of the pixels are within a filter area in the CIE color spaced based on the x, y values;
• (e) adjust a color of each of the pixels that are within the filter area away from a confusion line in the CIE space for the color blind person to provide a corresponding color-modified pixel;
• (f) generate a color-modified image composed of the color-modified pixels and original pixels, the original pixels corresponding to pixels having the input R, G, and B values located outside the filter area in the CIE color space;
• and
• (g) cause the electronic display to display the color-modified image.
