Real-time multifocal displays with gaze-contingent rendering and optimization

A computer program product comprising a non-transitory computer-readable storage medium having instructions encoded thereon that, when executed by one or more processors, cause the one or more processors to:

• determine a first pixel intensity value for each pixel of a plurality of pixels by applying at least one numerical iteration on a plurality of correlation values related to the plurality of pixels;
• determine a second pixel intensity value for each pixel of the plurality of pixels using the first intensity value and applying one or more numerical iterations;
• determine information about a gaze direction for an eye;
• modify the second pixel intensity value based on the information about the gaze direction;
• and
• determine a pixel intensity value for each pixel of the plurality of pixels to generate content for presentation, based on the modified second pixel intensity value.

A controller configured to:

• determine a first pixel intensity value for each pixel of a plurality of pixels by applying at least one numerical iteration on a plurality of correlation values related to the plurality of pixels;
• determine a second pixel intensity value for each pixel of the plurality of pixels using the first intensity value and applying one or more numerical iterations;
• determine information about a gaze direction for an eye;
• modify the second pixel intensity value based on the information about the gaze direction;
• and
• determine a pixel intensity value for each pixel of the plurality of pixels to generate content for presentation, based on the modified second pixel intensity value.
