A moving image reproducing apparatus includes an NIC. Still image data of respective frames forming moving image data fetched from the NIC is compressed still image data compressed in accordance with a JPEG 2000 format. When such the compressed still image data is expanded, a CPU decodes, in the order that is from a lower frequency, a plurality of EBC blocks forming one frame of the compressed still image data. However, a decoding amount of the EBC blocks is controlled based on a frame rate of the moving image data. The still image data corresponding to decoded frequency components is multiplexed with each other by an inverse DWT processing, thereby generating one screen of expanded still image data.
