IMAGE DATA SAVE SYSTEM IN IMAGE MEMORY BOARD

摘要

PROBLEM TO BE SOLVED: To store image data analogized or estimated to be most importance among image data stored in each storage area of a volatile memory for circulatingly storing image data to an image data saving nonvolatile memory. SOLUTION: The image data save system is provided with an image importance discrimination means 1 that discriminates whether or not image data in divided areas of a DRAM 5 are to be copied to a flush memory 4 that is a nonvolatile memory when the DRAM 5 being a volatile memory is set to a write inhibit state through production of a trigger signal and with an image importance discrimination reference selection switch unit 2 by which a user can select a criterion of the image importance by the image importance discrimination means 1.
