ABSTRACT:
Information setting apparatus for a camera comprises pulse generating circuitry, pulse counting circuitry and apparatus for visually displaying variable digital information represented by the pulse count in the pulse counting circuitry. The digital information displayed is changed by altering the pulse count stored in the counting circuitry. A manually operable switch stops the pulse input to the counting circuitry to fix the digital information displayed by the display apparatus in accordance with the desired setting. Apparatus is provided for projecting an image of the displayed information onto the camera film. In cameras provided with a viewfinder, the image of the displayed information is projected into the viewfinder field of view.
