Document Type and Number:

WIPO Patent Application WO/2017/078312

Kind Code:

A1

Abstract:

An image sensor according to various examples comprises: a pixel array including a plurality of pixels; an analog-digital converter, of a first group, for converting the amount of light acquired through the pixel array into a first digital signal; and an analog-digital converter of a second group, the analog-digital converter being adjacent to the first group and for converting the power supplied to the image sensor into a second digital signal. The electronic device according to various examples comprises a power supply module and an image sensor, wherein the image sensor comprises: a pixel array including a plurality of pixels; an analog-digital converter, of a first group, for converting the amount of light acquired through the pixel array into a first digital signal; and an analog-digital converter of a second group, the analog-digital converter being adjacent to the first group and for converting power, supplied from the power supply module to the image sensor, into a second digital signal. The electronic device according to various examples comprises: an image sensor; a power supply module for supplying power to the image sensor; and a power control module provided in the image sensor, wherein the power control module measures the power and is configured to transmit a feedback to the power supply module if the power deviates from a designated range. An operation method according to various examples comprises, in the image sensor comprising the pixel array, the analog-digital converter of the first group, and the analog-digital converter of the second group adjacent to the first group, the steps of: receiving power from outside of the image sensor; converting the amount of light acquired through the pixel array into a first digital signal by using the first group; and converting the power into a second digital signal by using the second group.
