PROBLEM TO BE SOLVED: To prevent a battery from being exhausted because consumption of mechanical shutter drive and other mechanisms, and power consumption by light emission occur at the same time. SOLUTION: Power consumption is smoothed by driving the closure of a shutter 16 after light emission of an LED 114 is stopped, whereby the number of photographable pictures can be increased. Alternatively, light emission may be continued in a range without exhausting the battery Bt by changing over the quantity of light. Alternatively, light emission of the LED 114 may be continued by a capacitor C during the operation of the shutter 16. COPYRIGHT: (C)2010,JPO&INPIT |
