Photometry controller for camera having an electronic flash controlling capability and capable of photometry of reflection from film surface

摘要

A photometry controller is provided for a camera having an electronic flash controlling capability and capable of photometry of reflection from film surface. The controller is operative, whenever the difference in the brightness between a main subject and its background exceeds a given value, to delay the timing when the integration of a photocurrent is to be initiated by a given time interval after the initiation of an exposure triggered by a shutter release in an automatic manner, thus allowing the proportion of the integrated flashlight from the electronic flash relative to natural light to be increased.
