PROBLEM TO BE SOLVED: To provide a method capable of easily fusing as many loops as possible. SOLUTION: It is assumed that a new generalized arithmetic operation is added and a vector with a total value of the respective lines is returned to an RG(reserve graphics) to which values of respective lines of pixels are added. Direct definition of a way to execute acumulation required for the new arithmetic operation to expand an RG language by using the new arithmetic operation and an arithmetic operation restricting condition is represented to an order of a cycle (by every line and any order is allowed for the order in the line and between the lines). Consequently, fusion of the loops is enabled by using a compatible arithmetic operation like a point arithmetic operation and a horizontal scanning, etc., as well as the restricting condition which is already represented for an original RG arithmetic operation.
