Abstract
An image sensing device is provided to include a pixel array of unit pixels, each pixel structured to respond to incident light to produce photocharges and including different photosensing sub-pixels at different locations within the unit pixel to detect incident light, different detection structures formed at peripheral locations of the different photosensing sub-pixels of the unit pixel, respectively, and configured to receive the photocharges that are generated by the different photosensing sub-pixels of and are carried by a current in the unit pixel, a unit pixel voltage node located at a center portion of the unit pixel and electrically coupled to electrically bias an electrical potential of the different photosensing sub-pixels, and a control circuit coupled to the different detection structures of the unit pixel to supply sub-pixel detection control signals to the different detection structures of the unit pixel, respectively.
