Abstract

Abstract A camera having a strobe incorporated therein including a strobe light emitter which moves between a retracted position in which the light emitter is retracted in a camera body and an operative position in which the light emitter emits strobe light. An emission mode selecting device selectively sets an automatic light emission mode, in which the strobe light emitter emits strobe light upon exposure, when the brightness of an object to be taken is below a predetermined value. A compulsive light emission mode is provided, in which the light emitter compulsively emits the stobe light upon exposure, regardless of the object brightness. A light emitter moving and controlling device moves the light emitter to a waiting position, located between the retracted position and the operative position, and to the operative position when the automatic light emission mode and the compulsive emission mode are selected, respectively.
