MULTIDYNAMICS VISION SENSOR

An electro-optical image acquisition device (10) comprises a plurality of light-sensing sub-blocks (20), a detected signal reading block (60) for reading the output signal from said photosensitive elements (80), row and column selection elements, which enable access to different photosensitive elements (80) of the device and the reading thereof by means of said detected signal reading block (60), and pixel discharge control circuitry configured to combine a plurality of input voltage signals (40) to generate a defined number of reset curves and to dynamically select, for each photosensitive element (80), an appropriate reset curve from among those available. The device allows to obtain areas of the matrix of photosensitive elements with different light dynamics within the scene itself and to obtain so-called "multidynamic" images. This allows to both optimize the quality of the image by enabling an overall dynamic response which can even exceed the dynamics of the individual photosensitive elements and to enable schemes which allow to maximize the information content if the image is subsequently processed by a computer. In a specific and particularly advantageous embodiment, the reset curves are propagated line by line, thus allowing operation in any light condition.
