摘要：
An imager with pixels having dual conversion gain. Each pixel has a dual conversion gain element coupled between two floating diffusion regions. When activated, the dual conversion gain element switches in a storage element to increase the charge storage capacity of the pixel. Pixel reset circuitry is coupled to the second floating diffusion region. In order to reset the first floating diffusion region and the storage element, the dual conversion gain element is activated during the reset operation.
