<p>There is provided an image compressing method, which comprises: partitioning a frame into a plurality of code blocks, each code block having consecutive coding passes; sequentially coding the code passes at each code block, wherein said coding at said each code block comprises: a) coding a first coding pass to produce code bits; b) calculating a rate of the code bits and a distortion; c) calculating a slope of the rate and the distortion; d) checking whether the calculated slope is smaller than a predetermined reference value; and e) if it is determined that the calculated slope is not smaller than the predetermined reference value, then coding the next coding pass and repeating step b) to step e).</p> |
