摘要: An image sensor having improved signal-to-noise ratio and reduced random noise and an image processing system are provided. The image sensor includes a pixel array including a pixel connected to a column line and configured to provide an analog pixel signal to the column line in response to at least one row control signal, and an analog-to-digital converter (ADC) that receives and converts the analog pixel signal into a corresponding digital pixel signal. The pixel includes a group of sub-pixels simultaneously selected by the at least one row control signal, such that each one of the sub-pixels in the group of sub-pixels provides a sub-pixel signal, and the analog pixel signal is an average of the sub-pixel signals provided by the group of sub-pixels.

摘要: An image sensor may include a first photo gate and a second photo gate each extending substantially in parallel in a first direction, the first photo gate and the second photo gate isolated from direct contact with each other in a second direction, the second direction substantially orthogonal to the first direction, a first overflow gate between the first photo gate and the second photo gate, the first overflow gate extending in the first direction, a first charge collection region on the first photo gate, a second charge collection region on the second photo gate and isolated from direct contact with the first charge collection region in the second direction, a first floating diffusion region that may receive first charge from the first charge collection region and output the first charge, and a second floating diffusion region that may receive second charge from the second charge collection region and output the second charge.

摘要: An image sensor includes a plurality of pixels, at least one of the pixels comprising: a photodiode configured to generate charges in response to light; and a pixel circuit disposed on the substrate, and including a storage transistor configured to store the charges generated by the photodiode, and a transfer transistor connected between the storage transistor and a floating diffusion node, wherein a potential of a boundary region between the storage transistor and the transfer transistor has a first potential when the transfer transistor is in a turned-off state, and has a second potential, lower than the first potential, when the transfer transistor is in a turned-on state.
