SENSING APPARATUS AND SENSING METHOD FOR GENERATING THREE-DIMENSIONAL IMAGE INFORMATION

摘要

A sensing apparatus includes an infrared light generating device, an image sensing unit, a processing circuit and a control circuit. The image sensing unit is arranged for detecting a first infrared light signal reflected from an object to generate a first sensing signal when the infrared light generating device is activated, and detecting a second infrared light signal reflected from the object to generate a second sensing signal when the infrared light generating device is deactivated. The processing circuit is coupled to the image sensing unit, and is arranged for generating three-dimensional image information of the object according to at least the first sensing signal and the second sensing signal, wherein the three-dimensional image information includes depth information. The control circuit is arranged for control activation and deactivation of the infrared light generating device, sensing operations of the image sensing unit, and signal processing operations of the processing circuit.
