IMAGE PROCESSING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of decreasing the capacity of a line memory and carrying out resize processing in units of blocks.

SOLUTION: The image processing apparatus is provided with an MPEG decoder 1 for decoding encoded data and outputting image data in units of blocks each having an 8×8 pixel size; a horizontal resize circuit 2 for applying resize processing to the image data outputted from the MPEG decoder in units of blocks in a horizontal direction; the line memory 3 with a capacity of one line for storing image data of a lowermost line of a block among output data from the horizontal resize circuit; a vertical resize circuit 4 for applying resize processing to output data from the horizontal resize circuit and the data stored in the line memory in a vertical direction; a memory controller 5; and a memory 6. The image data after being subjected to the resize processing in the horizontal direction can be stored in the line memory with a small capacity.
