ABSTRACT:
A digital image recording and reproducing apparatus includes a serial-to-parallel converter connected between an image memory and a data memory, for converting serial image data from the image memory into parallel image data, and a parallel-to-serial converter connected between the image memory and the data memory, for converting parallel image data from the data memory into serial image data. The serial-to-parallel converter is operated when the image data are to be transferred from the image memory to the data memory, and the parallel-to-serial converter is operated when the image data are to be transferred from the data memory to the image memory. Since the data can be transferred from the data memory to the image memory with a minimum number of bits required to allow displayed images to be recognized, the time required to reproduce images is shortened, and hence the image retrieval time is also shortened.
