摘要： The present invention relates to an electronic flash device capable of dimming control, particularly with the objective of enhancing the dimming precision in weak light emissions. The electronic flash device of the present invention thus predicts the quantity of overrun light after stopping of the emission based on the target quantity of emission, and performs correction to advance emission stop timing in accordance with the quantity of overrun light. Here, the rate between the target quantity of emission and the quantity of full emission by the emission means (the rate of emission) is preferably obtained so that the quantity of overrun light after stopping of the emission is predicted based on the rate of emission. In split emission, the emission stop timing is preferably corrected on each chopper emission.

摘要： A camera exposure control device reduces battery power consumption during film exposure at the picture shooting time for long exposure times greater than several seconds such as bulb shooting and time shooting. The camera exposure control device includes a power source line from a battery power source to a control device and the like. A DC/DC converter is also on the power line. The control device stops operation of the DC/DC converter during the long exposure time where the shutter time is longer than a predetermined time. In other words, the control device controls the operation of the DC/DC converter during film exposure at shooting times where the film exposure time is longer than several seconds. The control device interrupts the DC/DC converter during these long exposure times. Further, other electric parts such as IC's and devices that do not require electricity supplied during the long exposure times can be turned off by the control device.
