Abstract:
An image storing and processing device comprising:A/D conversion means for converting a video signal from a pick-up device to a digital video signal;image compression means for compressing said digital video signal and outputting image compression data;memory means for storing said image compression data;image expansion means for selecting the stored image compression data from the memory means for image expansion, and outputting the image compression data as image expansion data; andD/A conversion means for converting the image expansion data to an analog image signal;wherein said memory means includes a plurality of groups of memory areas divided in response to a previously set number of storable images, and a control means forces the memory means to store compressed image data while updating each of the memory areas of the same group at a predetermined time interval when no trigger signal is inputted, and controls the operation such that storage location is altered to the memory area of another group in response to an input of a trigger signal.
