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 25):
A method comprising:\n receiving, by one or more hardware processors of a video rendering computing system, video frame data for an image having a plurality of pixel values in multiple color channels for display on a head-mounted display (HMD) device; determining, by the one or more hardware processors, a primary region of the image to be displayed at full resolution and one or more secondary regions of the image to be displayed at less-than-full resolution; encoding, by the one or more hardware processors, the image to generate a modified copy of the image for transmission to the HMD device that is compressed in the secondary regions in a color-specific manner, including:\n retaining, for first pixel values of the received video frame data in the primary region, all of the first pixel values in the modified copy; and \n replacing, for second pixel values of the received video frame data in the secondary regions, and differently for one or more first color channels of the multiple color channels than for one or more second color channels of the multiple color channels, at least some of the second pixel values in the modified copy, by:\n dividing the second pixel values into multiple blocks each having a defined first number of multiple pixel values of a single color channel; \n creating smaller sub-blocks that represent the multiple blocks and that each has a second number of multiple pixel values smaller than the defined first number, including creating, for each block with pixel values of one of the first color channels, a single sub-block whose pixel values each represent two or more pixel values in the block, and further including creating, for each block with pixel values of one of the second color channels, multiple sub-blocks whose pixel values in aggregate replicate the block; and \n changing, for each sub-block, each pixel value in the sub-block to one of multiple allowed pixel values for the sub-block, including determining the multiple allowed pixel values for the sub-block to include minimum and maximum pixel values from the sub-block and to include one or more intermediate pixel values between the minimum and maximum pixel values; \n \n transmitting the modified copy to the HMD device; and displaying, under control of at least one controller for the HMD device, the image on the HMD device from the modified copy, including using the retained first pixel values to control display in the primary region, and using the replaced at least some pixel values to control display in the secondary regions by generating new blocks from the created sub-blocks and the changed pixel values.
