ABSTRACT:
An image processing apparatus includes an image processing section, a module table, a module storage section, and a program generation section. The image processing section compresses/encodes an image by using an intraframe code obtained by dividing an image into small blocks, performing orthogonal transform for each block, quantizing the transform result, and performing high-efficiency encoding the quantized result, and an interframe code obtained by performing motion search by searing for blocks of previous and subsequent frames such that the differences between the blocks and divided blocks of a current frame become minimum, calculating the differences between the blocks of the current frame and the blocks of the frames having undergone the motion search, performing orthogonal transform for the difference blocks, quantizing the transform result, and performing high-efficiency encoding for the quantized result. The module table is used to designate modules required to constitute an optimal image processing program for each type of CPU. The module storage section stores a plurality of modules designated by the module table. The program generation section generates an optimal image processing program for a CPU in use by loading designated modules from the module storage means with reference to the module table.
