Abstract
The horizontal processing circuits subject the image data input respectively to the compression processing or the expansion processing in the horizontal direction and output said processed image data. The transfer means composed of the bus controller 338 and the bus 333 transfers respective image data from the horizontal processing circuits time-divisionally. The vertical processing circuit 334 subjects the respective transferred image data to the compression processing or the expansion processing in the vertical direction time-divisionally. The post-processing circuit 335 and the display device 464 display the image data from the vertical processing circuit 334.
