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 19):
The system of  claim 18  further comprising memory of a rendering system with stored instructions that, when executed by one or more hardware processors of the rendering system, cause the rendering system to generate the encoded copy and to transmit the encoded copy to the HMD device by performing further automated operations that include at least:\n receiving, by the rendering system, data for the image that includes a plurality of pixel values belonging to the multiple color channels; \n generating, by the rendering system, the encoded copy of the image using color-specific compression in the secondary regions, including:\n retaining, in the encoded copy, pixel values of the received data in the primary region, and a size of color data for the retained pixel values; \n reducing, in the encoded copy, and for additional first pixel values in the received data for the secondary regions and belonging to the first color channel, a pixel quantity and a size of color data by, for each of multiple blocks of the additional first pixel values, replacing, in the encoded copy, the block with a single first sub-block of smaller size whose pixel values are each selected from a first reduced set of possible pixel values and each represent multiple of the additional first pixel values from the block; and \n reducing, in the encoded copy, and for additional second pixel values in the received data for the secondary regions and belonging to the second color channel, a size of color data by, for each of multiple blocks of the additional second pixel values, replacing, in the encoded copy, the block with multiple second sub-blocks whose pixel values are each selected from a second reduced set of possible pixel values; and \n \n transmitting, by the rendering system, the encoded copy of the image to the HMD device.
