ABSTRACT:
The present invention provides a television receiver which receives television signals to display images on a CRT display, and includes a JPEG decode unit (21) for decoding JPEG (Joint Photographic Experts Group) compressed image data. The JPEG decode unit (21) detects image size of image data after decode processing stored in JPEG compressed image data from a memory card (6). In case the image size is larger than image display area of a CRT display (3) and activity ratio of a memory unit (22) is larger than a limit value, the JPEG decode unit (21) sends the image size to a CPU (25), and concurrently decodes the JPEG compressed image data in the memory unit (22) to generate the image data, and clips away half of the image data along the vertical direction and the horizontal direction. The image data process unit (23) enlarges or reduces the image data so that the image data is displayed on substantially the whole image display area without changing the aspect ratio of the image data based on enlargement/reduction ratio which is determined by the CPU (25) by comparing the image size with the image display area of the CRT display (3).
