Abstract
Solid-state image capturing elements are disclosed. In one example, a solid-state image capturing element includes a noise-cancelling-signal generating circuit connected to a pixel power source. It executes a gain change and a polarity inversion on a first noise cancelling signal to output a second noise cancelling signal. The element also includes a DA converter that outputs a reference signal and converts a current of the second noise cancelling signal into a voltage to superpose the converted voltage on the reference signal; a comparator that receives inputs of the reference signal and a pixel signal and outputs an inversion signal according to the pixel signal and a gain setting; a counter that converts an inversion timing of the comparator into a digital value; and a gain controlling unit that outputs, when changing a gradient of the reference signal and an input capacity to execute a gain control on the comparator.
