    Abstract: An image sensing circuit includes floating node, switch circuit, capacitor(s), and counting circuit. The floating node receives image electric charge from a photosensitive pixel. The switch circuit is coupled between floating node and capacitor(s) to dynamically connect and disconnect floating node and capacitor(s). The capacitor(s) include(s) first terminal(s) connected to switch circuit and second terminal(s) connected to ground. The counting circuit counts the number of charging and discharging behavior of capacitor(s) according to dynamic switches of switch circuit wherein the switch circuit dynamically switches to make capacitor(s) be charged and discharged dynamically in response to one exposure time period to receive energy of image electric charge which is determined by the number of charging and discharging behavior of the capacitor(s) and the capacitor(s)' potential value measured finally.
