Abstract
An image sensing device includes a pixel array suitable for generating a pixel signal, a tracking circuit suitable for generating a tracking signal whose voltage level gradually converges to a voltage level of the pixel signal by selectively using any one of a first convergence voltage where an amount of decrease in a voltage level gradually decreases during a plurality of tracking periods and a second convergence voltage where an amount of increase in a voltage level gradually decreases during the tracking periods for each tracking period, based on the pixel signal and first and second comparison result signals, and a signal generation circuit suitable for generating the first and second comparison result signals and an image signal based on the pixel signal and the tracking signal.
