Abstract
An image sensor includes a pixel array including at least one unit pixel configured to generate accumulated charges, a correlated double sampler configured to perform a correlated double sampling operation to extract an effective signal component based on a signal component and a reset component from the unit pixel for at least first and second read-out periods, the correlated double sampler configured to read out an image signal during the first read-out period and to read out a light noise signal during the second read-out period, an analog-digital converter configured to convert the image signal into a first digital signal and to convert the light noise signal into a second digital signal and an image compensator configured to generate a compensated image signal based on the second digital signal and the first digital signal.
