Claim:
1. A method of operation of an image processing system comprising: receiving a raw image block of a source image from an imaging device; forming a coefficient block by performing a transform operation on the raw image block, the transform operation including a wavelet transform or a discrete cosine transform; calculating a coefficient significance vector for a current bitplane of the coefficient block, the coefficient significance vector having a significant value set at each index position having a non-zero value at a higher bitplane; calculating a partition significance vector for the current bitplane of the coefficient block, the partition significance vector having the significant value for each coefficient partition having a non-zero value; calculating a run-length coded value for a portion of the partition significance vector; calculating a Golomb coded value for a portion of a significant partition; forming an encoded block having the run-length coded value and the Golomb coded value; and forming a bitstream having the encoded block.
