Original Abstract Submitted
an image sensing device for obtaining an image of a scene by sensing light is disclosed. the image sensing device includes a pixel circuit configured to output a pixel signal based on a voltage level of a floating diffusion node at which charges generated corresponding to an intensity of incident light are accumulated, a voltage controller configured to control a voltage level of an output node where the pixel signal is output in response to a voltage control signal, a conversion circuit configured to convert the pixel signal into a digital signal, and a voltage trimming circuit configured to control the voltage control signal based on the digital signal.
