Abstract:
Techniques are described for controlling image display via compression of image data in some image regions while performing less or no compression in other (e.g., peripheral view) regions, with color-specific compression preserving chromatic aberration compensation. Such techniques may be used with display panel(s) of a head-mounted display device used for virtual reality display. A primary region of an image at which to encode and display data at a highest resolution level may be determined by tracking a gaze of a user, while other secondary regions may be selected to be surrounding or other outside the primary region. In the secondary regions, image data for a first (e.g., green) color channel may be encoded at a first compression level for a first resolution level lower higher than for other second color channels, and HDR data may be compressed at higher compression levels than the color-specific data.

Claim (Index 1):
A method comprising:\n receiving, by one or more hardware processors, data for an image having a plurality of pixel values for display on a display panel, including target pixel values in a primary region of the image that belong to multiple color channels, first pixel values in one or more secondary regions of the image that belong to a first color channel of the multiple color channels, and second pixel values in the secondary regions that belong to a second color channel of the multiple color channels; generating, by the hardware processors, a compressed copy of the image to transmit to the display panel that retains the target pixel values of the primary region and reduces resolution in the secondary regions by removing at least some of the first and second pixel values in a color-specific manner, including:\n reducing, using a first compression level, first information in the compressed copy that represents the first pixel values for the first color channel, wherein the first compression level reduces a quantity of pixel values in the first information and selects each pixel value in the first information from a reduced set of first possible pixel values with less unique values than the first pixel values; and \n reducing, using a second compression level, second information in the compressed copy that represents the second pixel values for the second color channel, wherein the second compression level has less compression than the first compression level and selects each pixel value in the second information from a reduced set of second possible pixel values that has less unique values than the second pixel values without reducing a quantity of pixel values in the second information; and \n transmitting, by the hardware processors, the compressed copy of the image to the display panel to cause display of the image on the display panel.
