Original Abstract Submitted
an image sensing device and a light detection and ranging (lidar) device include a single-photon avalanche diode (spad) array including spad pixels, a signal transmission unit including row lines connected in units of spad pixels of a same row and column lines connected in units of spad pixels of a same column, a bias circuit unit outputting a row bias signal corresponding to a row photon signal transmitted through a row line of the signal transmission unit and outputting a column bias signal corresponding to a column photon signal transmitted through a column line of the signal transmission unit, a logic circuit unit identifying, based on the row bias signal and the column bias signal, a spad pixel that has detected a photon, and a counter array performing photon counting with respect to a counter that corresponds to the identified spad pixel among counters corresponding to the spad array.
