    Abstract: An image sensor includes a substrate, and a pixel separation pattern disposed in the substrate and interposed between a plurality of unit pixels. The plurality of unit pixels include a first unit pixel region and a second unit pixel region adjacent to the first unit pixel region in a first direction. The first unit pixel region and the second unit pixel region respectively include a first transfer gate and a second transfer gate. The pixel separation pattern includes a first pixel separation part interposed between the first unit pixel region and the second unit pixel region, and a second pixel separation part spaced apart from the first pixel separation part in the first direction. A top surface of the first pixel separation part is lower than a top surface of the second pixel separation part.

    Abstract: A method of driving an image sensor includes integrating an overflowed charge from a photodiode in the floating diffusion area and a dynamic range capacitor. The dynamic range capacitor is formed between the floating diffusion area and a power supply voltage. The method further includes sampling a first voltage formed in the floating diffusion area by the integrated overflowed charge, resetting the photodiode, the floating diffusion area, and the dynamic range capacitor, sampling a reset level of the reset floating diffusion area, transferring a charge accumulated in the photodiode to the floating diffusion area, and sampling a second voltage formed in the floating diffusion area.
