DEFINITION

Classification: 396/252

Including memory capacitor:

(under subclass 251) Subject matter in which the RC circuit contains at least one capacitor to store a voltage proportional to a scene brightness for a period of time during which the exposure control circuit cannot sense the scene brightness.

(1) Note. A single capacitor which performs both memory and timing is proper for this subclass.
