Abstract
A display device for a camera in which a first display, showing a film feeding state, is presented by time-serially driving a plurality of patterns arranged in a row, and a second display, showing photographic information, is presented by selectively driving a particular one of the patterns. Circuitry is provided for inhibiting the second display during a period in which film feeding is in progress, thereby enabling the use of the same patterns for the two displays.
