Abstract
The present invention discloses a gesture recognition apparatus including a substrate, a light emitting device, an image sensor and a processing unit. The light emitting device is for emitting a light beam according to a first clock signal. The image sensor is disposed on the substrate and is for receiving the light beam reflected by an object according to a second clock signal to generate an object image. The processing unit is disposed on the substrate and is for recognizing the object image detected by the image sensor to provide a command signal. There is a correlation between a period of the first clock signal and a period of the second clock signal. The present invention also provides a complex optical apparatus.
