Abstract

See full text

An optical sensor apparatus includes an infrared light generating device, N first detection devices, a second detection device and a processing circuit. In addition to detecting infrared light, the N first detection devices further detect N different visible wavelength ranges, respectively. The second detection device is optically shielded from visible light and arranged for detecting infrared light. In a first sensing mode, the processing circuit obtains color information according to N first detection signals generated by the N first detection devices and a reference signal generated by the second detection device. In a second sensing mode, the N first detection devices and the second detection device generate (N+1) second detection signals when the infrared light generating device is activated, and generate (N+1) third detection signals when the infrared light generating device is deactivated. The processing circuit recognizes gesture information according to the (N+1) second and the (N+1) third detection signals.
