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.
Claims46
A method, comprising:
- receiving, by a processing device, initial image data for a frame fi comprising a plurality of pixels, wherein data for each pixel in the frame fi is received sequentially over a respective clock cycle of the processing device and comprises a value, ri, for a first color, a value, gi, for a second color, and a value, bi, for a third color;
- producing, by the processing device, modified image data for a frame fm corresponding to the frame fi, by concurrently performing operations of a sequence of operations on data for a subset of the pixels, wherein a different operation of the sequence is performed per clock cycle on data for a different pixel of the subset, and the operations of the sequence are performed sequentially on data for each pixel over corresponding sequential clock cycles, wherein the operations of the sequence comprise
- determining, for each pixel in the subset, a relative level of stimulation of cones in a viewer's eye based, at least, on the value, ri, for the first color and the value, gi, for the second color;
- and
- modifying, based, at least, on the determined relative level of stimulation of cones in a viewer's eye by the pixel, the initial image data for the frame fi, the modified image data for the frame fm comprising a value, rm, for the first color and a value, gm, for the second color for the pixel;
- and
- transmitting, by the processing device, the modified image data for the frame fm to an electronic display, wherein data for each pixel in the frame fm is transmitted sequentially over a respective clock cycle.
