Abstract: An image sensor includes a substrate including a pixel array region and an optical black region surrounding the pixel array region, a micro lens over the pixel array region, a dummy lens over the optical black region, and a blocking bar over the optical black region. A length of the blocking bar is greater than a length of the micro lens and a length of the dummy lens. A top surface of the blocking bar is curved.
