Zusammenfassung:An image sensing device may include a pixel circuit and a driving control circuit. The pixel circuit is configured to store photocharge, generated by a photoelectric conversion element, as image information. The driving control circuit may control the pixel circuit to adjust the signal conversion gain ratio depending on the illuminance of the incident light at the image sensing device.
