Abstract
An image sensor is provided. The image sensor includes: a pixel array with a pixel area and a dummy area; a row driver configured to sequentially output driving signals to the pixel array; a detection circuit configured to receive a row output signals generated based on the driving signals from the dummy area, and receive the driving signals; and a timing controller configured to provide the driving signals to the row driver, and the driving signals and a clock signal to the detection circuit. The detection circuit is further configured to identify difference values between delay times corresponding to adjacent rows of the rows, determine whether the rows are defective by comparing the difference values with a reference value, and output result values indicating whether the rows are defective.
