Abstract
An image sensing device capable of detecting a distance to a target object according to a time-of-flight (TOF) method is disclosed. The image sensing device includes a pixel configured to generate a pulse signal based on photons reflected from a target object, the pixel including a light receiving element of which sensitivity is controlled according to a quenching control voltage, a time-to-digital converter (TDC) configured to count the number of the photons to output a photon counting value, and a controller configured to adjust a level of the quenching control voltage based on the photon counting value.
