Claim 0:
1. An optical sensing system, comprising:
a processing circuit;
an optical sensor, configured to sense first optical data respectively in first sensing time intervals; and
a TOF (Time of Flight) optical sensor, configured to sense second optical data respectively in second sensing time intervals;
wherein the processing circuit computes a distance between a first object and the optical sensing system according to the second optical data;
wherein the first sensing time intervals do not overlap with the second sensing time intervals;
wherein the second sensing time intervals are set based on triggering of start of the first sensing time intervals;
wherein the second sensing time intervals are set according to a first set time interval, a second first set time interval, and an initialization time interval;
wherein the first set time interval starts at a start time of the first sensing time interval and is larger than the first sensing time interval;
wherein the initialization time interval, which is a time interval in which the TOF optical sensor completes preparation of sensing the second optical data, is after the first set time interval;
wherein the second set time interval starts after the initialization time interval, larger than the second optical sensing time interval and covers the second optical sensing time interval.
