Abstract
A resolution transformation apparatus which has longitudinal and lateral change ratio input means for inputting the longitudinal and lateral change ratios of an image, low-frequency orthogonal transformation block extraction means for extracting only low-frequency areas of N orthogonal transformation blocks required for resolution transformation from before-transformation orthogonal transformation image memory for storing orthogonal transformation images before undergoing resolution transformation, resolution transformation means for executing resolution transformation and generating M orthogonal transformation blocks from the N low-frequency orthogonal transformation blocks, and orthogonal transformation block storage means for storing the Morthogonal transformation blocks after resolution transformation in after-transformation orthogonal transformation image memory
