PURPOSE: To simplify a circuit by successively distributing the pixel of a present block to all calculating channels, circulating the pixel of a search window, forming a partial sum at the fixed position of a circuit, and calculating specific deviation or deformation corresponding to displacement by each processor. CONSTITUTION: A picture to be processed is divided into blocks which respectively have an M*N size. The M indicates the number of lines and the N indicates the number of the pixel of the line. The number of calculating channels is equal to the number of possible movement or deviation in any case, and a basic sequence is repeated plural times as necessary until an M*N cycle is operated. For example, four calculation is operated in parallel in each calculating cycle 0, 1, 2, and 3. In each cycle, all channels receive a coefficient Xm ,n and each calculates the partial item d(Xm ,n *, ym+1 ,n+1 ) of 9 global deformation. In this way, an arithmetic operation is limited to only multiplication and totaling, and a desired result is obtained by the characteristics of scan. |
