Abstract
A data access apparatus has a memory portion including plural memory banks. A data storage control portion stores the pixel data in the plural memory banks with the pixel data being divided into the plural memory banks based on information on an access pattern of plural pixels set on a predetermined screen. A data access control portion reads pixel data relative to the plural pixels specified by the access pattern at the same time from the plural memory banks at each set position in which the set position of the access pattern moves from the start position thereof toward a pixel row direction. A selector portion transmits pixel data corresponding to respective pixels constituting each of the groups of pixels based on correspondence information on input and output. Each group of pixels includes a center pixel and peripheral pixels positioned at a periphery of the center pixel.
