Filed: 1994-09-20
Abstract: PURPOSE: To continuously record and reproduce images just before the generation of any natural phenomenon or the other phenomenon as well by recording image information in a second storage means after the phenomenon is detected and a detecting signal is outputted. CONSTITUTION: A CPU 3 sets an address shown by an address pointer 3-1. Next, the image information outputted from an image processing part 2 is stored in the address of a semiconductor storage device 4. When a trigger signal generating part 6 detects the change of image information and outputs a trigger signal, the CPU 3 sets the address shown by the address pointer 3-1. Next, the image information outputted from the image processing part 2 is stored in the address of the semiconductor storage device 4. Namely, after the trigger signal is outputted from the trigger signal generating part 6, the CPU 3 successively stores the image information in the other area of the semiconductor storage device 4.  Thus, the image information is written in the semiconductor storage device 4 or a magnetic storage device 5 continuously before and after the trigger signal generating part 6 outputs the trigger signal.
