Patent ID: 7812875

Claim:
A signal processing circuit for signal-processing an analog picture signal outputted from a solid-state imaging device that comprises: a pixel part arranged two-dimensionally; an electronic shutter shift register that supplies an electronic shutter shift pulse to a pixel part for resetting an electric charge of said pixel part; and a readout shift register that supplies a vertical readout shift pulse to said pixel part for reading out said electric charge of said pixel part in order, said signal processing unit comprising: a drive unit, an A/D converter, a processing unit for picture signal, and a control unit, wherein said drive unit supplies each of said shift pulses separately to said electronic shutter shift register and said readout shift register, said A/D converter converts said analog picture signal outputted from said solid-state imaging device to a digital picture signal, said processing unit for picture signal designates a control start position of said digital picture signal outputted from said A/D converter and performs interpolation processing thereon along a horizontal direction and a vertical direction, said control unit controls said drive unit and said processing unit for picture signal, said drive unit extends a horizontal blanking period of said solid-state imaging device to be longer than a valid period during one line of said analog picture signal, and said processing unit for picture signal performs vertical-line interpolation processing to extend a part of picture area of said digital picture signal.
