Abstract
A photographic camera apparatus with electronic image enhancement operates to control the exposure of a photosensitive material to scene light received directly from a scene to be photographed in a manner whereby the photosensitive material is exposed to an extent less than a selected optimum exposure value and the scene light is simultaneously electronically sensed to provide electrical signal information corresponding thereto to control an additional electronic exposure of the photosensitive material so that in conjunction with the direct exposure to scene light there is substantially provided the selected optimum exposure value.
Claims10
A photographic camera apparatus comprising:
- means for controlling the exposure of a photosensitive material to scene light received directly from a scene of which an image is to be recorded in a manner whereby the photosensitive material is exposed to an extent less than a selected optimum exposure value;
- means for sensing the scene light from the scene to be photographed during said photographic exposure and converting said sensed scene light to electrical signal information corresponding to said sensed scene light;
- and
- means responsive to said electrical signal information for exposing said photosensitive material to supplemental illumination which in conjunction with said direct exposure to scene light substantially provides the selected optimum exposure value.
