Patent attributes
The present invention provides an image pickup device in which a column noise component 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 the effective pixel area A are corrected, based on the detected column noise component. The image pickup device includes a solid-state image pickup element having a pixel part including an effective pixel area to be irradiated with light, and a light-shielded pixel area where irradiation of light is shielded, a vertical scanning circuit, a horizontal scanning circuit, and an output circuit, a controller that controls the solid-state image pickup element 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 that generates a predetermined control signal, a noise component detector that detects noise, and a noise corrector that corrects noise contained in the pixel signals from the effective pixel area based on a noise component detected by the noise component detector, wherein the control signal generator generates different control signals at predetermined timing.
