Title:
SOLID-STATE IMAGE CAPTURING DEVICE, METHOD OF DRIVING SOLID-STATE IMAGE CAPTURING DEVICE, AND ELECTRONIC INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2017/030007
Kind Code:
A1
Abstract:
This technology relates to a solid-state image capturing device, a method of driving a solid-state image capturing device, and an electronic instrument, which make it possible to reduce power-supply noise in pixel signals by means of a single-ended circuit configuration. This solid-state image capturing device is provided with: a pixel unit in which a plurality of unit pixels which perform opto-electrical conversion are arranged; a power-supply noise detecting unit which detects a noise component of a power supply used to drive the unit pixels, and outputs a single-ended cancellation signal including a cancellation component which cancels out the noise component; a sample-and-hold unit which samples a single-ended pixel signal output from a unit pixel, and holds and outputs a pixel signal obtained by removing the noise component from the sampled pixel signal on the basis of the cancellation signal; and an A/D converting unit which performs A/D conversion of the held pixel signal. This technology is applicable to CMOS image sensors, for example.
