ABSTRACT:
An image coding apparatus includes an image dividing circuit for dividing an image signal of one frame into a plurality of blocks, an amount-of-data calculator for computing the amount of data representing fineness of a picture included each block, a bit-assignment determining circuit for distributing all coding bits usable for encoding the image signal of one frame to the individual blocks, to each block a number of bits which has been determined by the amount of data of the block, a quantizer for quantizing the image signal for each block and outputting a quantization signal, and an encoder for encoding the quantization signal in accordance with the number of bits of each block determined by the bit-assignment determining circuit.
