Abstract: A device for increasing the dynamic range of a camera comprising a lens (2) which forms a picture (6) of a scene (1) on a primary electronic image sensor (3) having a first dynamic range, a second image data source (4) corresponding to one picture of said scene (1), and an electronic image processing circuit (5), which combines the data from the primary image sensor (3) and the data from the second image data source (4) and provides image data representing the scene (1) as observed and represented by said image data, with a ratio between the brightest and dimmest areas of said scene (1) which is greater than the dynamic range of a primary image sensor (3). In various embodiments, the second image data source (4) is either a secondary image sensor or a memory which stores a previously sensed image from the primary image sensor (3).

Abstract: An image processing device having 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, an analysis device (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 the screen a state control signal which is a function of the representative signals delivered by the analysis means, the sensor and the screen receiving images of same objects, these images being transmitted or reflected by the screen. The device is more particularly suited to be used in the photographic industry.
