    • PROBLEM TO BE SOLVED: To provide an image processor and processing method, allowing computation at a computation time shorter compared with that in the prior art, in the computation of an optical flow. SOLUTION: An OPF computation processor 20 includes a PIC computation circuit 25 for generating a hierarchical image data by carrying out sampling and filtering for image data of two frames, and an OPF computation circuit 30 (including computation circuits 28, 29) for computing a spatial brightness gradient matrix and a mismatch vector, based on the generated hierarchical image data, and for computing the optical flow, based on the computed spatial brightness gradient matrix and the mismatch vector. The OPF computation circuit 30 computes the optical flow, while repeating four pixel values within an area including four pixels adjacent each other, in a prescribed pixel order using those as a unit, as to an area adjacent to the area.
