カメラの閃光撮影用露出制御装置。[Scope of Claim for Utility Model Registration] 1. Has an automatic exposure control mode of aperture priority mode or shutter priority mode, and in flash photography, the integrated value of the subject light that passes through the aperture of the photographic lens and is reflected from the film surface during film exposure. In a flash photography device that controls the amount of light emitted by an electronic flash based on the following, a data output means that outputs fixed value data for the aperture or shutter speed, a metering means, and whether or not to perform AE lock are manually set. a calculation means that operates when the setting means sets the AE lock and calculates an exposure control value based on the set value and the AE locked photometric value; Flash photography for a camera, characterized in that it is equipped with an exposure control means for flash photography that controls the exposure with the set value and the above-mentioned calculated value when AE lock is set, and with the set value and the above-mentioned fixed value when AE lock is not set. exposure control device. 2. The photometering means has a light receiving means that measures the average brightness of the entire photographic screen, and the exposure control value calculated by the calculating means is a value that is a predetermined amount underexposure from the appropriate exposure. An exposure control device for flash photography of the camera according to item 1.
