State imaging device

To provide a solid-state imaging device, the solid-state imaging device comprising: generating a plurality of pixels of the photoelectric conversion signal; and an output corresponding to a column of pixels is small, respectively, by a first gain and a second gain amplifier larger photo columns of the first signal and the second signal switching signal generated by the amplification unit; means for analog to digital converter (21) the first signal and the second signal from an analog signal into a digital signal; means for analog to digital converter from gain error between the first signal and the second input digital signal, the first signal and the shifted second signal level the ADC is converted to the same gain level, and then detecting the level-shifted a comparison unit (224); and means for error correction based on the gain correction unit (226) of the first and second signals.
