发明名称 PHOTOGRAPHIC CAMERA WITH ARTIFICIAL ILLUMINATION CONTROL
摘要 <p>A photographic camera apparatus is provided with an automatic illumination and exposure control system for controlling a pair of scanning type shutter blade elements as well as a flash fire and quench signal directed to a quench strobe operatively associated therewith. The camera apparatus may be operated in either a "fill-in" flash mode of operation or an ordinary flash mode. During the "fill-in" flash mode of operation, the time delay in quenching the strobe is progressively decreased as a function of increasing ambient scene light intensity so that the shutter blade elements admit progressively less reflected strobe light from the subject during the finite time required for the shutter blade elements to close.</p>
