1. A method of operation of an image processing system comprising:
obtaining an input image block with a capture device; generating a transformed image block based on the input image block, the transformed image block having wavelet coefficients and a low pass subband and a coarsest high pass subband of the wavelet coefficients; organizing binary values of the wavelet coefficients into bitplanes each with a bitplane priority value; generating a scaled wavelet block by increasing the bitplane priority value for the bitplanes of the low pass subband and the coarsest high pass subband of the wavelet coefficients with a scaling factor; generating a compressed image block by scanning and coding the bitplanes of the scaled wavelet block; and generating an output image block by decoding, resealing, and performing an inverse wavelet transform on the compressed image block for display on a display device.
