摘要： An image sensor includes first pixels, second pixels and a deep trench. The first pixels are formed in an active region of a semiconductor substrate, and configured to measure photo-charges corresponding to incident light. The second pixels are formed in an optical-black region of the semiconductor substrate, and are configured to measure black levels. The deep trench is formed vertically in a boundary region of the optical-black region, where the boundary region is adjacent to the active region, and configured to block leakage light and diffusion carriers from the active region.

摘要： An image sensor is provided including a pixel array, a correlated double sampling (CDS) unit, an analog-digital converting (ADC) unit, a control unit, and an overflow power voltage control unit. The pixel array includes at least one unit pixel that generates accumulated charges corresponding to incident light in a photoelectric conversion period and outputs an analog signal based on the accumulated charges in a readout period. The CDS unit generates an image signal by performing a CDS operation on the analog signal. An ADC unit converts the image signal into a digital signal. A control unit controls the pixel array, the CDS unit, and the ADC unit. An overflow power voltage control unit controls an overflow power voltage to have a low voltage level in the photoelectric conversion period and controls the overflow power voltage to have a high voltage level in the readout period.
