Abstract

It is intended to improve reading speed of pixel signals in a solid-state imaging element provided with an ADC. A plurality of pixels are arrayed in a pixel block. A drive circuit drives the pixel block to output a plurality of pixel signals at the same time. A comparator successively selects the plurality of pixel signals and compares the selected pixel signals and a predetermined reference signal. A control section generates a control signal for updating the predetermined reference signal on the basis of comparison results of the comparator. A reference signal update section updates the predetermined reference signal according to the control signal.
