Time-of-flight distance measuring system and calibration method

A calibration method for a time-of-flight distance measuring system, the calibration method comprising:

• generating a plurality of delay signals, wherein the plurality of delay signals correspond to a plurality of delay times;
• generating a plurality of delayed pulses according to the plurality of delay signals;
• emitting a plurality of delayed pulsed lights corresponding to the plurality of delayed pulses;
• receiving a plurality of delayed reflected lights corresponding to the plurality of delayed pulsed lights to generate a plurality of pixel signals corresponding to the plurality of delay times;
• storing a correspondence between the plurality of delay times and the plurality of pixel signals;
• and
• performing a time-of-flight distance measuring according to the correspondence between the plurality of delay times and the plurality of pixel signals.
