<P>PROBLEM TO BE SOLVED: To determine an optimal prediction mode with a small throughput. <P>SOLUTION: An image coding apparatus is characterized by a generated code amount estimating part 54 which comprises: code amount information outputting means (65 to 67) of outputting a value based on occurrence probability for each binary symbol in an input string of binary symbols, as information on a code amount; and a code amount accumulating means 64 of adding the code amount given by the information from the code amount information outputting means and outputting an estimate of a generated code amount when the binary symbol string is encoded arithmetically. <P>COPYRIGHT: (C)2008,JPO&INPIT |
