Abstract
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.
Claims4
A moving image reproducing apparatus that reproduces a plurality of encoded image signals generated by encoding, for each frequency component, still image signals of respective screens forming a moving image signal, comprising:
- a decoder for decoding, in the order of a lower frequency, a plurality of the encoded image signals corresponding to one screen;
- a multiplexer for multiplexing with each other a plurality of the decoded image signals decoded by said decoder so as to generate one screen of a decoded still image signal;
- and
- a controller for controlling a decoding amount by said decoder.
