摘要： According to one embodiment, a solid-state imaging device includes a pixel unit, a flicker detecting unit, a flicker-level estimating unit, and a flicker correcting unit. The flicker detecting unit detects, based on a magnitude relation of a signal amount in each of lines formed in the pixel unit, presence or absence of a flicker. The flicker-level estimating unit estimates a flicker level in each of the lines of the next frame. The flicker correcting unit corrects, for each of the lines, a flicker that occurs in a signal of an image picked up by the pixel unit.

摘要： According to one embodiment, in a pixel array unit, pixels that accumulate photoelectrically converted charges are arranged in a matrix shape. A vertical signal line transmits a signal read out from the pixels in the vertical direction. An acceleration circuit shifts the potential of the vertical signal line in advance before a signal is read out from the pixels. The acceleration control circuit controls timing for shifting the potential of the vertical signal line in advance. The timing control circuit generates a control signal for controlling the acceleration control circuit.

摘要： A pixel section outputs R, G and B signals which are obtained by photoelectrically converting light incident on R, G and B pixels. An adding section determines a prescribed area in which a certain pixel is set as a central pixel, and adds the R, G and B signals from the central pixel and peripheral pixels arranged on the periphery of the central pixel in the prescribed area in order to produce an addition signal. A ratio calculating section calculates an average value of each of the R, G and B signals, and a ratio coefficient of the average value of each of the R, G and B signals to a total value of the average values. An RGB generating section generates a new R signal, G signal and B signal by using the addition signal and the ratio coefficients calculated by the ratio calculating section.
