Classification: CPC G  H | IPC G  H

Claim 0:
1. A light sensor, comprising:
a light source;
a sensing sub-pixel, comprising a diode; and
a control circuit, coupled to the light source and the sensing sub-pixel, and configured to operate the diode in a Geiger mode or an avalanche linear mode,
wherein the control circuit comprises a time-to-digital converter coupled to the sensing sub-pixel, and the time-to-digital converter comprises:
a counting circuit, coupled to the sensing sub-pixel, and comprising a plurality of counting units,

wherein when the time-to-digital converter receives a sensing signal provided by the sensing sub-pixel, the time-to-digital converter generates a plurality of counting values according to the sensing signal through the counting units of the counting circuit, wherein the counting values are histogram data corresponding to a distance sensing result.
