摘要：The present invention provides an image pickup device in which a column noisecomponent is detected in a short time without being influenced under variant random
noise even if the VOPB area B includes a small number of lines, and pixel signals from theeffective pixel area A are corrected, based on the detected column noise component. Theimage pickup device includes a solid-state image pickup element having a pixel partincluding an effective pixel area to be irradiated with light, and a light-shielded pixel areawhere irradiation of light is shielded, a vertical scanning circuit, a horizontal scanningcircuit, and an output circuit, a controller that controls the solid-state image pickupelement such that the pixel signals outputted from the pixels arranged in the light-shielded pixel area or the pixel signals outputted from the pixels arranged in the
effective pixel area are outputted from the output circuit, a control signal generator thatgenerates a predetermined control signal, a noise component detector that detectsnoise, and a noise corrector that corrects noise contained in the pixel signals from theeffective pixel area based on a noise component detected by the noise componentdetector, wherein the control signal generator generates different control signals atpredetermined timing.
