    摘要: An electronic flash charging circuit for use with a camera having a power source common to a microcomputer that controls a plurality of camera functions and to an electronic flash. The charging circuit has a booster circuit for boosting a charging voltage with which a main capacitor of the electronic flash is charged and a controller that causes the booster circuit to operate intermittently, thereby intermittently charging the main capacitor.
