METHOD AND APPARATUS EMPLOYING DUAL PHOTOCELLS FOR REMOVING SPECTRAL FILTER DURING STROBE PULSE

摘要

6209 Method and apparatus for automatically switching between alternate ones of a pair of light sensing photocells having different photoresponsive characteristics in an exposure control system usable with a photographic apparatus. Included in the system is a light integrating circuit responsive to a first one of the photocells until commencement of a flash mode and then to the other until termination of such flash mode at which time the circuit is again responsive to the first photocell.
