Abstract
A strobe control device for a camera has a light receiving element for receiving and integrating light reflected from a film surface of a film used in the camera. The strobe control device further includes a controller which controls a strobe to emit light. The controller controls the strobe to stop emitting light when the amount of light integrated by the light receiving element reaches a threshold value. The threshold value is adjusted so that the effects on the amount of light received by the light receiving element are canceled when predetermined parameters of a photographing optical path of the camera are changed.
