Abstract
A segmenting section divides an input image into a plurality of segments. A hierarchizing section determines classes of the respective segments according to a predetermined criterion, and produces a class identification signal indicating the classes of the respective segments. A coding section encodes the segmented image signal into code data while changing the value of a coding control parameter for each of the segments in accordance with the class identification signal. Examples of the coding control parameter are a coding time interval and precision of quantization.
