Claim 21:
22. An image compression and storage system comprising:
a processor; and
a processor memory local to the processor, wherein the processor memory has stored thereon instructions that, when executed by the processor, cause the processor to perform:
determining a residue corresponding to an original sample based on a mapped previous reconstructed sample;
generating a biased residue based on the residue;
quantizing the biased residue based on a maximum allowed error to generate a quantized biased residue;
encoding a value corresponding to the quantized biased residue to generate an encoded value corresponding to the original sample for storage in a storage medium;
decoding the encoded value to generate a decoded value corresponding to a quantized biased residue;
generating a reconstructed biased sample based on the decoded value;
generating a mapped reconstructed sample based on the reconstructed biased sample; and
inverse mapping the mapped reconstructed sample to an unmapped reconstructed sample based on a high priority sample value, a bit depth of the original sample and a maximum allowed error.
