Zusammenfassung:FIELD: television cameras, working under conditions of complex lighting and/or complex brightness of objects, when simultaneously strongly and weakly lit objects and/or objects with sharp difference in brightness may be in camera field of view. ^ SUBSTANCE: components of combined image are formed in charge form on targets of first and second television sensors with various exposition times, optimal for each one of transferred scene fragments. Due to that, in output image of television camera, bright and light parts are transferred same as in prototype, without limitation of white, while dark and/or low light parts are transferred with high signal/noise ratio, and dynamic range of brightness degrees is therefore extended. ^ EFFECT: extended dynamic range of brightness degrees for control objects, transferred in combined image outside the "window" due to increase of signal/noise ratio for dark and/or low light parts of objects. ^ 6 cl, 4 dwg
