Abstract

Processing digital information made up of a plurality of n-bit samples is performed by raising each n-bit value to an x-bit value, x being greater than n. The x-bit values represent mid-band values, wherein in this context a band includes a sequential set of x-bit values having n most significant bits in common and a mid-band value is then an x-bit value approximately centered between the lowest and highest x-bit values of a band including that mid-band value. In some embodiments, the digital information may comprise video information. Thus, the process may be applied prior to converting the video information from a first color space (e.g., a red-green-blue (R-G-B) color space) to a second color space (e.g., a luminance-chrominance (Y-Cr-Cb) color space). For a particular embodiment, n may be equal to five or six, and x may be equal to eight, however, in general n may be variable amongst different ones of the samples.
