Abstract
A video camera which comprises a progressive scanning CCD, a camera signal processing part for converting an output from the progressive scanning CCD to a video signal adaptive to video display, and a driving means for driving the progressive scanning CCD, and which enables to enlarge dynamic range by synthesizing a first signal obtained by exposure during a first predetermined time and a second signal obtained by exposure during a predetermined time after the exposure time of the first signal by means of the progressive scanning CCD to enlarge luminance gradation characteristics on appearance further includes at least a separating portion for separating the first signal and the second signal which are output from the progressive scanning CCD at different timings, a signal synthesizing portion for synthesizing the first signal and the second signal to produce a synthesized signal, and a delay portion for receiving the first signal output from the separating portion and for delaying the first signal by a predetermined time so that the second signal and the first signal are simultaneously input to the signal synthesizing portion.
