PROGRAM-SEARCHING REPRODUCTION SYSTEM IN IMAGE MEMORY BOARD

摘要

PROBLEM TO BE SOLVED: To retrieve an image before and after an image calculated as important on the basis of a prescribed criterion and to reproduce the image in a device that has a semiconductor memory to cyclicly record image data. SOLUTION: A control means 4 stores an amount of image data outputted from an image compression means 1 for each image to a prescribed area of a data memory 5a sequentially every time the amount of the image data for each one image is outputted. The control means references a change in the amount of the image data for each image stored in a data processing semiconductor memory to calculate an image being a criterion of program searching in the case of conducting program searching reproduction to read the image data for each image from the image data recording semiconductor memory 3.
