ABSTRACT:
Embodiments of image processing are described that include receiving source image data including a range of values having endpoints, adjusting the source image data by treating at least one subset of endpoint data differently from data having midrange values, where adjusting the source image data is performed prior to compressing the source image data, and restoring a range of values between the endpoint data values after decompressing image data to maintain the midrange data values substantially unadjusted.
