Title:
IMAGE SENSOR, ELECTRONIC APPARATUS, CONTROL DEVICE, CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/110484
Kind Code:
A1
Abstract:
The present technology relates to an image sensor, an electronic apparatus, a control device, a control method, and a program by which it is possible to achieve both a higher S/N and a higher frame rate. An A/D conversion unit has a comparator in which differential pairs are provided at an input stage. The differential pairs each include a plurality of transistors as a first transistor and a second transistor which are the pair of transistors constituting the differential pair. The A/D conversion unit performs A/D conversion on an electric signal by comparing a reference signal with a changing level to an electric signal outputted by an imaging unit that outputs an electric signal by performing photoelectric conversion. The comparator is controlled such that, according to the amount of light entering the imaging unit, transistors to be operated among the plurality of transistors are selected as active transistors and the active transistors are operated. The present technology can, for example, be applied to an image sensor or the like that captures images.
