ABSTRACT:
An image encoding control system includes an orthogonal transform encoder for carrying out orthogonal transform coding for each block which includes transform coefficients related to a plurality of blocks, each block obtained by dividing one picture of an input image signal into the plurality of blocks, a code control for controlling the transform coefficients obtained for each block so that the number of variable-length code words obtained for each block is equal to or smaller than a predetermined number of variable-length code words, a variable-length encoder for converting the transform coefficients obtained for each block into variable-length code words, and a buffer memory for temporarily storing the variable-length code words output by the variable-length encoder for each block.
