PROBLEM TO BE SOLVED: To clarify the characteristics of an automatic light control processing operation and to feed them back to design and manufacture. SOLUTION: Automatic light control processing by an electronic shutter function is performed at an interval of 1/60 second, and the data of an electronic shutter speed which changes matched with the automatic light control processing are tentatively stored in a RAM 23 for every second as frequency distribution data. Then, the frequency distribution data in an EEPROM 18 are updated on the basis of the electronic shutter speed data in the RAM 23 once in every six minutes and the frequency of the pertinent electronic shutter speed is added.
