Title:
FLASHED LIGHT EMISSION CONTROLLER FOR CAMERA
Document Type and Number:
Japanese Patent JPH01137243
Kind Code:
A
Abstract:
PURPOSE:To obtain flashed light necessary for photographing environment by comparing the way that power has been accumulated with a threshold regarding photographing conditions obtained from a camera, displaying the compared results and varying the threshold according to the photographing conditions. CONSTITUTION:A control part 16 monitors the power source voltage VC of a stroboscopic light emitting part 10, and outputs a flashed light emitting OK display on a display part 32 when the voltage VC reaches the threshold corresponding to a guide number at that time. The threshold for discriminating whether said display is output or not varies according to the calculated guide number. When an operator confirms the display on the display part 32 and operates a shutter release button 30, the control part 16 responds to that operation, controls exposure in a photographing part 14 according to exposure quantity corresponding to brightness measured in a photometric part 12, and photographs the object. In synchronization with the photographing, the control part 16 also controls the stroboscopic light emitting part 10 to flash light. In such a way, flashed light necessary for photographing environment can be obtained.
