Abstract: An image sensor, imaging device, and method are provided. The image sensor includes a pixel array including an active area in which plural active pixels are located, and a dummy area in which plural dummy pixels are located, and a test element group (TEG) which is located in the dummy area and on which a test light-shielding pattern, different from a light-shielding pattern formed on the active area, is formed to detect a degree of misalignment between the light-shielding pattern and the active area.
