ABSTRACT:
A method and apparatus for controlling image compression is disclosed. A current block of pixels is firstly compressed. The average pixel size of the compressed current block is averaged with an average pixel size of preceding block or blocks to obtain an average value. The compressed current block is passed as output, if the average value is not greater than a target value; otherwise a portion of the current block prior to compression is truncated and then passed as the output.
