PURPOSE:To calculate the data of real number coordinates with high accuracy and high efficiency by using 2<n> pieces of memory modules in parallel with [nXn] picture elements as a block unit. CONSTITUTION:With the adjacent [2X2] picture elements as the block unit, a picture is divided into blocks and the positions of the [2X2] picture elements in each block are respectively made correspondent to memory modules 1a-1d. Then, a position relation between the respective blocks is held and the respective picture element data of the picture are respectively distributed and written to the memory modules 1a-1d. Respective memory control parts 2a-2d efficiently calculate the 2<2> pieces of integer coordinates, which are required for calculate the data of the designated real number coordinate by primary interpolation, around the real number coordinates by simple arithmetic control and respectively simultaneously read out the data of the respective integer coordinates from the respective memory modules, and the data at the real number coordinates are calculated with high accuracy by the primary interpolation. Thus, arithmetic processing time is shortened and processing speed can be increased. |
