Foveated color correction to improve color uniformity of head-mounted displays

Abstract:

A color correction mask programmatically generated in software on an HMD device is applied to a gaze region on a display field of view (FOV) on a head-mounted display (HMD) device to optimize system resources while rendering a display. Eye monitoring sensors are utilized to track movement of a user's eyes while the user operates the HMD device to determine a gaze position of the user's eyes on the display FOV. Using the determined gaze position, a dynamic foveal gaze region is sized around the gaze position so that the foveal portion of the display FOV is color-corrected, that is, color non-uniformities are reduced or eliminated. In other implementations, a gaze-based weighting mode is implemented in which measurements of the user's full eye or eye orbit are utilized to color correct a larger surface area of the display FOV relative to the foveal color correction mode.
