    Abstract: 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.

    Abstract: Provided are a unit pixel, an image sensor including the same, a portable electronic device including the same, and a method of manufacturing the same. The method of manufacturing includes: forming a photoelectric conversion region in a substrate; forming, in the substrate, a first floating diffusion region spaced apart from the photoelectric conversion region of the substrate, and a second floating diffusion region spaced apart from the first floating diffusion region; forming a first recess spaced apart from the first floating diffusion region and the second floating diffusion region by removing a portion of the substrate from a first surface of the substrate; filling the first recess to form a dual conversion gain (DCG) gate that extends perpendicularly or substantially perpendicularly from the first surface of the substrate; and forming a conductive layer to fill an inside of the first recess.

    Abstract: An image sensor includes a pixel array. The pixel array includes a plurality of sensing pixels and at least two focusing pixels adjacent to each other. Each of the sensing pixels is configured to output an image signal corresponding to an amount of light incident on the sensing pixels. The at least two focusing pixels are configured to output a focusing signal corresponding to a phase difference between light incident on the at least two focusing pixels. Each of the sensing pixels and the at least two focusing pixels includes a semiconductor layer including a photodetecting device. Each of the sensing pixels includes a light guide which guides incident light toward the photodetecting device, and each of the at least two focusing pixels does not include the light guide.

    Abstract: A pixel array includes an array of pixels to receive light, a first pixel to be blocked from receiving the light, and a circuit to adjust signals output from pixels in the array based on a signal from the first pixel. The signals output from the pixels in the array include a first error value. The circuit reduces the first error value in the signals from the pixels in the array based on the signal from the first pixel. The circuit may also reduce a second error value in the signals output from the pixels in the array based on a signal from a second pixel. The first and second pixels may be outside of the pixel array. The first and second error values may be storage diode leakage value and a dark current value.

    Abstract: An apparatus and a method for capturing images are disclosed. The apparatus for capturing images includes an active pixel sensor (APS) array including a plurality of active pixels each including a photo diode and a storage diode, the plurality of active pixels being arranged in an array of N rows and M columns (where N and M are natural numbers of 2 or more), and an image signal processor that corrects an image signal output by the APS array. The APS array includes N pixel sensor rows, and the image signal processor removes noise from the image signal by using image signals that are sequentially output from non-adjacent ones of the pixel sensor rows.

    Abstract: An image sensor includes a light-electron conversion unit, a signal generation unit, and a selection unit. The light-electron conversion unit generates photo-charges from incident light. The signal generation unit accumulates photo-charges from the converter in a storage node during a detection period, and then generates a first analog signal and a second analog signal during an output period. The analog signals are generated based on an amount of photo-charges accumulated in the storage node. The selection unit generates an image signal based on one of the first analog signal and the second analog signal.
