Patent ID: 7411622

Claim:
A video signal processor, comprising: a CCD for storing an inputted image by converting it into an electric charge through photoelectrical conversion to be stored by each field and then outputting said stored electric charge by each field; a shutter pulse generator for supplying a shutter pulse which adjusts storage time of said electric charge in said CCD; and a variable controller for variably controlling adjusting amount of electric charge storage time by said shutter pulse by a field unit; wherein said variable controller, after setting plural shutter pulses with electric charge storage time being different from each other, alternately arranges said set shutter pulses, respectively, on a time base by corresponding to plural continuous fields; said variable controller, as said plural shutter pulses, sets a first shutter pulse having electric charge storage time equivalent to a time length of a field and a second shutter pulse having electric charge storage time shorter than that of said first shutter pulse; and said variable controller omits setting of said first shutter pulse.
