ABSTRACT:
The digital image output apparatus comprises a digital image decoder (1a) for decoding encoded digital image data and outputting image data update information (V2); an image data transfer area control unit (7) for determining a portion of the image data which has been updated in encoding according to the image data update information (V2) and outputting a result of the determination (VCT); an image data transfer unit (2a) for transferring digital image data (V1A) from the digital image decoder (1a) to an LCD memory (4) on the basis of the output signal (VCT) from the image data transfer area control unit (7); and the LCD memory (4) for storing the digital image data (V1A). A low-power digital image output apparatus is implemented by transferring image data depending on whether the image data has been updated in encoding of a digital image.
