Abstract
An image sensing device includes a pixel configured to generate a pixel signal having a single photon avalanche diode (SPAD) pulse by detecting incident light, a time-to-digital converter (TDC) configured to generate time-to-digital converter (TDC) data representing a time of flight (TOF) for the SPAD pulse, and a TDC memory configured to store the TDC data in a unit memory that is determined from among a plurality of unit memories according to the number of occurrences of the SPAD pulse.
