1. An apparatus comprising:
an interface configured to receive a set of pixel data; and
a compression circuit configured to:
perform a channel transform on the set of pixel data to generate a channel transformed set of pixel data wherein a channel transform for a given pixel comprises calculating a difference between at least two different channels of the given pixel;
perform a comparison of the channel transformed set of pixel data to the set of pixel data in original form; and
compress the channel transformed set of pixel data to represent the original set of pixel data responsive to the comparison meeting a first condition.
