1. An image processing device of scene light from an object, comprising an image sensor and a flat image transfer screen both arranged to receive scene light from the same object, an image receiving surface placed optically downstream of the flat transfer screen, said image sensor comprising a first network of image points or pixels, said image sensor being adapted to generate for each of the pixels of the first network a signal representative of an optical parameter of the scene light, said first network being connected to a processing means and for delivering thereto said representative signals, said flat screen comprising a second network of image point or pixels, said processing means generating state control signals as a function of said representative signals, memory means connected to said processing means for storing the state control signals generated by said processing means, said processing means also being connected to said second network for transferring said state control signals from said memory to corresponding ones of said pixels of said second flat screen, and said flat screen defining means for modulating the scene light for optical transfer to said receiving surface.
