Claim 4:
5. A system, comprising:
one or more processors;
memory that stores computer-executable instructions that, if executed, cause the system to:
determine whether a first block of pixels of a plurality of block of pixels comprising a first frame of image data contains at least one edge;
select, based on whether the block of pixels contains the at least one edge, a type of compression from a plurality of compression types that includes lossy compression and lossless compression;
obtain at least one first value associated with at least one second block of pixels adjacent to the first block of pixels, wherein the at least one first value comprises pixel values associated with the at least one second block of pixels;
compress the first block of pixels based on the at least one first value and using the selected type of compression to yield a compressed block of pixels, wherein the at least one second block of pixels is compressed separately from the first block of pixels; and
set at least one second value associated with the first block of pixels to indicate at least one of the compressed value or the type of compression used to compress the first block of pixels.
