Abstract:
1. An image coding apparatus, comprising: a judgment part for judging whether a macroblock to be coded should be intra-coded or inter-coded so that all macroblocks are intra-coded once in N frame period; and a coding part for coding said macroblock to be coded, on the basis of a determination result of said judgment part, wherein said judgment part includes a first conversion part for extracting the lower-order K bits of a numerical value J to thereby generate a numerical value L which can take a value of 2 a second conversion part for extracting the lower-order K bits of a numerical value P to thereby generate a numerical value Q which can take a value of 2 a generation part for generating a numerical value S which is uniquely determined from a combination of said numerical value M and said numerical value R; and a determination part for extracting the lower-order K bits of a numerical value T to thereby generate a numerical value U which can take a value of 2
