Claims
- 1. A moving image processing apparatus for expanding compressed moving image data and displaying the expanded data, comprising;
- first storage means for storing the compressed moving image data;
- second storage means for storing the compressed moving image data stored in said first storage means;
- expansion means for expanding the compressed moving image data stored in said second storage means, and for adjusting the expansion speed to a predetermined display speed of the moving image; and
- means for supplying the expanded moving image data output from said expansion means to a display monitor,
- wherein said second storage means includes at least a first memory and a second memory in order to perform read-out of the compressed moving image data from said first storage means to said second storage means and read-out of the compressed moving image data from said second storage means to said expansion means in parallel.
- 2. The apparatus according to claim 1 further comprising dynamic changeover means for changing over an input-output of data by dynamically changing the first memory and the second memory, which are hard disks.
- 3. A moving image processing apparatus for expanding compressed moving image data and displaying the expanded data, comprising;
- first storage means for storing the compressed moving image data;
- second storage means for storing the compressed moving image data stored in said first storage means;
- expansion means for expanding the compressed moving image data stored in said second storage means, and for adjusting the expansion speed to a predetermined display speed of the moving image;
- means for supplying the expanded moving image data output from said expansion means to a display monitor;
- image processing means for reading the compressed moving image data out of said first storage means and performing data processing, or forming a new image data not depending upon the compressed moving image data;
- a first data bus for the transfer of the image data formed by said image processing means to said display means; and
- a second data bus for the transfer of the compressed moving image data from said first storage means through said second storage means to said expansion means.
- 4. The apparatus according to claim 3, wherein said image processing means includes expansion and compression means for expanding the compressed moving image data and compressing the newly formed image data and third storage means for storing the moving image data expanded by said expansion means.
- 5. A moving image processing method for expanding a compressed moving image data and displaying the expanded data, comprising the steps of:
- instruction step of instructing a reproduction mode of moving image data;
- retrieval step of retrieving administrative information of the compressed moving image data, which is stored in a first storage medium in accordance with the reproduction mode;
- read-out step of reading the compressed moving image data out of a second storage medium which is accessible separately from the first storage medium, in accordance with the administrative information retrieved in said retrieval step; and
- expansion and display step for expanding the compressed moving image data read out in said read-out step and displaying the expanded data.
