Abstract
An image sensor includes a plurality of pixels. Each pixel includes a first photo diode, a floating diffusion node, a first capacitor, a second capacitor, a first sampling transistor, and a second sampling transistor. The first sampling transistor is configured to sample charges from the first capacitor. The second sampling transistor is configured to sample charges from the second capacitor. The image sensor operates the first capacitor to store one of reset charges according to a voltage of the floating diffusion node reset and signal charges according to a voltage of the floating diffusion node in which the photo charges are accumulated, operates the second capacitor to stores the other one of the reset charges and the signal charges and changes types of charges stored in each of the first capacitor and the second capacitor.
