| 摘要 |
The invention provides a method and apparatus for performing optical navigation. The optical navigation apparatus comprises a first light source, a second light source, an optical sensor that converts light into electrical signals, and processing logic. The processing logic is configured to process the electrical signals output by the optical detector to obtain information relating to motion or an absence of motion of the optical navigation apparatus. Based on the motion information obtained, the processing logic turns on the first light source and turns off the second light source, or vice versa. This ensures that, regardless of the tracking surface, the optical navigation apparatus will be using a light source that enables the optical navigation apparatus to operate effectively.
