Abstract

A pixel array for an image sensor is provided. The pixel array includes a dark pixel which is configured to detect a local dark current in an active pixel block. The dark pixel is distinguished from an optical black pixel block which is arranged around the active pixel block and is configured to detect a global dark current. The pixel array is configured to compensate for dark shading, which is not compensated through global dark current compensation, using the local dark current output from the dark pixel which is arranged within the active pixel block.
