Abstract

PURPOSE:To expand a photographing range, by operating and calculating both a diaphragm value and an exposure time so that they are varied in accordance with such various information as distance information, light emission intensity information and film sensitivity information, at the time of flat light emission of a light emission device. CONSTITUTION:This device is provided with a focal plane shutter SH, a light emission device 3 which is capable of switching to flash light emission and flat light emission, and a switching means AC1 for switching to either flash light emission or flat light emission. Furthermore, it is provided with an operation means E6 for calculating a diaphragm and an exposure time so that both the diaphragm and the exposure time are varies in accordance with such various information as distance information from a distance information generating means VR1, light emission intensity information from a light emission intensity information generating means E2 and film sensitivity information from a film sentivity information generating means VR2, at the time of the flat light emission device 3.
