Abstract

A camera is provided with a small array of character-forming display elements for recording data upon a film concurrently with each picture image. Such data may comprise, for example, the chronological date, time of day or other data related to the picture being taken by the camera.

Data Recording Apparatus for Cameras

A camera is provided with a small array of character-forming display elements for recording data upon a film concurrently with each picture image. Such data may comprise, for example, the chronological date, time of day or other data related to the picture being taken by the camera.

Fig. 1 shows one exemplary arrangement in which an array of light-emitting diodes (LEDs) is positioned within the camera body to project data upon the film without obstructing the projection of the picture image thereon. A built-in timing circuit whose operating cycle is initiated by a manual start switch enables the LED display to be activated for a timed period sufficient to provide the proper exposure. The formation of characters by the LED array is controlled in a suitable manner through a plug connection to a computer, microprocessor, hand calculator, attached solid-state clock or other instrumentality.

Fig. 2 shows an alternative arrangement in which the timing of the film advance and generation of the associated display characters may be controlled optionally from an external source. Operation of such a system may be controlled to occur at preset times or in response to predetermined conditions.

The use of an LED or equivalent character-forming display enables auxiliary data to be generated without requiring the use of a separate shutter to control the exposure thereof. The display can be mounted in any convenient position. For instance, it...
