ABSTRACT:
A block boundary information analyzing circuit extracts block boundary information from an input image signal. A blocking circuit divides the input image signal into block images while changing block boundary positions based on the block boundary information every time a coding operation is performed. A discrete cosine transform coder codes the respective block images. A block boundary information adding circuit adds boundary information to the coded image information.
