发明名称 IMAGE SENSOR AND METHOD OF STABILIZING A BLACK LEVEL IN AN IMAGE SENSOR
摘要 An image sensor includes a substrate, an anti-reflection board and a light shielding film. The substrate includes first pixels to receive a light, and second pixels to provide a black level compensation. The first pixels are formed in an active region and the second pixels are formed in a first region spaced apart from the active region in a row direction. The anti-reflection board is formed in a second region above the substrate, and the second region is between the active region and the first region. The light shielding film is formed above the anti-reflection board, and the light shielding film covers an optical black region including the first and second regions. Therefore, the image sensor may be used in a CCD type image sensor and a CMOS type image sensor to provide a stabilized black level, thereby improving a quality of a displayed image.
