There is disclosed a method of an apparatus for displaying accurate camera-to-subject range information in alphanumeric form in a viewfinder of camera along with information as to whether a good or bad picture will be obtained of the subject at the sensed range and in the sensed scene brightness.

Method of and apparatus for displaying alphanumeric range in camera

A photographic camera having a single source of internal electrical power, an electronic flash that includes a flashtube and a charging system for storing an electrical charge for subsequent discharge across the light emitting element of the flashtube, a manually actuatable self-timer for generating an exposure interval initiating electrical signal a predetermined time after the timing cycle of the self-timer has been actuated and apparatus for generating electrically produced visual and/or audible signals indicating that the self-timer is in operation is provided with apparatus for inhibiting the operation of the electronic flash charging system whenever such signals are generated in order to prevent the relatively large electrical load associated with the electronic flash charging system from changing the voltage and/or current levels available from the camera's power source and thereby preclude interferance with the proper operation of the self-timer operation indicators which are sensitive to such changes.

Photographic camera with electronic flash having periodically disabled

A photographic camera system for use with film units of the self-developing type including control means for providing a sneak charge of the electronic flash between the exposure interval and the film transport interval in order to reduce the apparent flash charge time subsequent to the transport of the film unit from the camera even though the overall charge time for the electronic flash remains unchanged.
