Title:
PHOTOGRAPHIC CAMERA WITH COMPOUND CONTROLLER
Document Type and Number:
Japanese Patent JPS59102218
Kind Code:
A
Abstract:
A "hybrid" exposure control system for a photographic camera apparatus controls exposure in response to both the firing of a quench strobe at an appropriate size aperture corresponding to the determined camera-to-subject distance and to the subsequent quenching of the strobe in response to the detection and integration of reflected strobe light from the scene in correspondence with the scene light admitted to the film plane. An increased degree of exposure correction can thus be made possible since a slight error in determining the camera-to-subject range can be compensated by the detection and integration of reflected strobe light to provide a flash quenching signal.
