Abstract
An apparatus comprising an interface and a processor. The processor may be configured to determine a grid size for a compression operation in response to a source bit-depth and a compressed bit-depth, divide the image frames into grids in response to the grid size, analyze the pixel data for each of the grids to determine a gain and an offset for the grids, process the grids in response to the gain and the offset, calculate a value at the compressed bit-depth for each of the pixel data, store compression parameters in an image header, and generate a compressed image frame comprising the image header and the values for the pixel data at the compressed bit-depth. The compression parameters may comprise a table of the gain and offset for each of the grids. The compression operation may convert the pixel data from the source bit-depth to the compressed bit-depth.
