Image sensor and operation method thereof
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.
