摘要： A photosensor arrangement for providing an exposure influencing control signal in a photographic camera apparatus includes an array of photoresponsive elements (P 1 -P 4 ) each arranged to have a different field of view, signal-generating means (R 14 -R 22 ) for generating the exposure-influencing signal in response to signals from the photoresponsive elements, and means (R 1 -R 8 ; D 1 -D 8 ; A,-As; 10-24) controlling the transmission of the output signals from the photoresponsive elements to the signal-generating means (R 14 -R 22 ) and operative to block the signal path to the signal-generating means from the photoresponsive element or elements detecting the highest and/or lowest scene light intensity, or from any photoresponsive element which detects a scene light intensity which is above a maximum light intensity threshold and/or any photosensitive element which detects a scene light intensity which is below a minimum light intensity threshold.

摘要： 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.

摘要： Image processing device comprising at least an image sensor, a flat image transfer screen and a computer, characterized by a sensor (3) arranged as a first network of image points or pixels, analysis means (6, 4) adapted to generate for each pixel of the sensor a signal representative of at least one parameter, and at least a flat screen (18, 20, 25) organized according to a network of image points or pixels in association with processing means (5, 9) intended to elaborate for each pixel of said screen a state control signal which is a function of the representative signals delivered by said analysis means, said sensor and said screen receiving images of same objects, these images being transmitted or reflected by said screen. The device is more particularly intended to be used in the photographic industry.
