ABSTRACT:
A header information analysis section analyzes header information of a compressed image file and reads an original image size while comparing the read original image size and an image size required for display and performing an operation of a size ratio. A JPEG expansion section expands image data of the image file by MCU. A resizing section magnifies or reduces by MCU the image data expanded by the JPEG expansion section according to the size ratio obtained by the header information analysis section and transfers the magnified or reduced data to a display frame memory.
