An image encoding apparatus has an encoder for encoding low-resolution image information as priority image information in hierarchical encoding, another encoder for encoding non-priority image information other than the priority image information, a first code quantity controller for controlling a sum total of the generated code quantities of both the priority image information and the non-priority image information within a predetermined value and a code quantity limiter for limiting the generated code quantity of the priority image information within a predetermined ratio to the sum total code quantity. <IMAGE>
