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: 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 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.
