Abstract
A one-dimensional orthogonal transformation device group constituted with a plurality of one-dimensional orthogonal transformation devices performs one-dimensional orthogonal transformation to the pixel data of one block that is inputted to an input device. A memory device stores the one-dimensional orthogonal transformation data of one block. A selector selects either the pixel data that is inputted via the input device or the one-dimensional orthogonal transformation data that is stored in the memory device, and outputs it to the one-dimensional orthogonal transformation devices. When the pixel data is inputted via the selector, the one-dimensional orthogonal transformation devices generate the one-dimensional orthogonal transformation data by performing first one-dimensional orthogonal transformation processing simultaneously to the pixel data corresponding to a plurality of rows of m-pixels, and store the one-dimensional orthogonal transformation data to the memory device. Further, when the one-dimensional orthogonal transformation data corresponding to the plurality of columns of the n-pixels that are stored in the memory device is inputted sequentially via the selector, the one-dimensional orthogonal transformation devices generate two-dimensional orthogonal transformation data by performing second one-dimensional orthogonal transformation processing to the one-dimensional orthogonal transformation data corresponding to the plurality of columns of the n-pixels.
