Abstract
An image sensing device includes a pixel array including a unit pixel suitable to transfer and store charges in response to a transfer signal and read out a pixel signal corresponding to the stored charges in response to a selection signal provided to the unit pixel; a signal converter suitable for comparing the pixel signal with a ramp signal based on a switch signal to generate a distance information signal; and a signal controller suitable for generating the switch signal for initializing the signal converter in a temporal section where the pixel signal is read out.
