PURPOSE:To reduce a picture memory to be required, and in addition, to realize high-speed processing at the time when two-dimensional picture data is interpolated by executing one-dimensional interpolation twice in a first and a second directions. CONSTITUTION:The picture data inputted from a picture data input part 301 is interpolation-arithmetic-processed in the first direction (vertical direction) by a first interpolation arithmetic processing part 307. From the point of time when this interpolation arithmetic processing proceeds to a state that the interpolation arithmetic processing in the second direction (horizontal direction) is possible, the picture data is interpolation-arithmetic-processed in parallel in the second direction by a second interpolation arithmetic processing part 309, and the picture data after the interpolation is outputted from a picture output part 310. |
