ABSTRACT:
This invention provides a multi-standard observation camera fitted with a detector which comprises photosensitive elements arranged in two aligned and/or offset rows, a clock sequencer (22) placed in the same plane as the detector (20), this clock sequencer (22) being used to control the transfer of charges from the sensors into a CCD read circuit (24) to output a video signal compatible with the display monitor television standard. The clock sequencer (22) includes programmable counting resources which define the periods during which the charges are integrated and times at which they are transferred into the read circuit (24), these counting resources being programmed via a link (28) to a memory (25) containing the data required to define several standards. The memory (25) is part of a set of proximity electronics (26) and is controlled by a selection command (27) to match the monitor standard.
