Abstract
An integrated circuit includes at least one photosensitive element capable of delivering an electrical signal when light of at least one wavelength of the visible spectrum reaches it, and an electrooptic system functioning as an electrochemical shutter. The electrooptic system is located in the path of at least one light ray capable of reaching the photosensitive element and possesses at least one optical property, dependent on electrochemical reaction, that can be modified by an electrical control signal. The optical property is preferably transmission.
