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.
