Abstract: According to one embodiment, a solid-state imaging device is configured as follows. A pixel array portion is configured such that pixels storing photoelectrically converted charge are arranged in an m (m is a positive integer) by n (n is a positive integer) matrix. A column ADC circuit calculates, for each column, an AD-converted value of a pixel signal read from the pixel based on a comparison result between the pixel signal and a reference voltage. The redundant column ADC circuit can relieve each column of the column ADC circuit. The column selection circuit can make a selection for each column so that the pixel signal input to the column ADC circuit is also input to the redundant column ADC circuit.
