Abstract:
A method of operating an image sensor includes: generating a pixel signal according to intensity of incident light; and generating a digital pixel signal based on a comparison between the pixel signal and at least one reference current. Accordingly, a current output from a 1T pixel in the image sensor is sensed such that the influence of noise is reduced and a pixel signal is sensed more precisely.
