摘要

PROBLEM TO BE SOLVED: To obtain a motion predicting mechanism predicting a motion at a high speed while simplifying a circuit constitution.;SOLUTION: In the integer-pixel motion predicting mechanism, a RAM_-HIME 21 used for an integer-pixel motion prediction for an IME 11 stores the brightness data D1 of an integer pixel from an SDRAM 1 while satisfying conditions improving a reading efficiency regarding an extraced rectangular region 42. Alternately, a RAM_-HSME 23 used for a quarter-pixel motion prediction by an SME 13 stores a partial quarter-pixel brightness data S12 while satisfying conditions improving an efficiency in acquisition by the arithmetic operation of an calculated rectangular region 48. Alternately, a RAM_-HMEC 24 used for generating the color-difference data of a quarter-pixel accuracy by a QPG 14 stores the color-difference data D2 of the integer pixel from the SDRAM 1, while satisfying conditions improving the efficiency in acquisition by the arithmetic operation of the calculated rectangular region 40U and the calculated rectangular region 40V.;COPYRIGHT: (C)2008,JPO&INPIT
