Abstract: Disclosed is an image sensor. The image sensor includes an active pixel sensor array including first to fourth pixel units sequentially arranged in a column direction, and each of the first to fourth pixel units is composed of a plurality of pixels. A first pixel group including the first and second pixel units is connected to a first column line, and a second pixel group including the third pixel unit and the fourth pixel unit is connected to a second column line. The image sensor includes a correlated double sampling circuit including first and second correlated double samplers and configured to convert a first sense voltage sensed from a selected pixel of the first pixel group and a second sense voltage sensed from a selected pixel of the second pixel group into a first correlated double sampling signal and a second correlated double sampling signal, respectively.

Abstract: An image sensor and an operation method of the image sensor are disclosed. The image sensor includes a pixel array and a row driver. The pixel array includes a first pixel and a second pixel. Each of the first pixel and the second pixel includes at least one photosensitive element and a switching element configured to transfer charges generated by the at least one photosensitive element to a floating diffusion node. The first pixel and the second pixel are connected to a same column line. The row driver is configured to provide a clamping control signal to the switching element in the first pixel. The clamping control signal transits from a first level to a second level that is less than the first level, during a read period of the second pixel.
