ABSTRACT:
A power supply system for a camera supplies electrical power to a light measuring circuit, a display circuit and others. During a hold state before the camera turns into a standby state, the power supply system supplies a boosted electrical power intermittently to the light measuring circuit, the display circuit and others, so that photographic information such as shutter speed and aperture value based on the measurement of the light measuring circuit are displayed on a display and power consumption in the hold state can be made small.
