Abstract
A data output apparatus includes a disk drive for driving a magneto-optical disk. Compressed image data recorded on the magneto-optical disk is transferred from the magneto-optical disk to an SDRAM according to a transfer instruction set in an instruction list and then output through an expansion process by a JPEG codec. A size of the compressed image data for which the transfer instruction is set in the instruction list and which has not yet been transferred to the SDRAM, and a size of the compressed image data for which the transfer instruction is set in the instruction list and which has not yet been expanded are detected by a CPU. The CPU suspends an output of an expansion instruction to the JPEG codec when a difference between the detected sizes is below a threshold value.
