Abstract
An image sensing device may include a pixel array. The pixel array includes a sensing region including a plurality of unit pixels, each unit pixel configured to detect incident light to generate photocharge indicative of the detected incident light, a bias field region doped with impurities and disposed along an edge of the sensing region and a contact portion connected to the bias field region to apply a bias voltage to the bias field region to move the photocharge in the sensing region.
