The invention provides an optical navigation system and an optical navigation device of the optical navigation system. The optical navigation system comprises a host computer and the optical navigation device. The host computer detects a run program to generate a control signal, and the optical navigation device is connected with the host computer in a wireless mode and used for receiving the control signal and carrying out efficiency configuration according to the control signal to adjust the number of image data needed to be processed. According to the optical navigation system, various programs run on the host computer are detected to generate the corresponding control signals, and the optical navigation device can carry out efficiency configuration according to the control signals to adjust the number of the image data needed to be processed to the proper degree; power consumption can be reduced, the frequency for replacing batteries or carrying out charging is further reduced, and the total cost for replacing the batteries is reduced.
Description
technical field [0001] The invention is an optical navigation system and an optical navigation device thereof. More specifically, the optical navigation device of the present invention adjusts an image data amount to be processed according to a control signal received from a host, wherein the control signal is generated by the host detecting an operating program. Background technique [0002] With the popularization of personal computers, various optical navigation devices (eg, mouse, trackball) have been widely used to control the cursor in the operating system. Since some application programs in the operating system require higher performance for controlling the cursor, there are optical navigation devices with different specifications on the market for users to choose. [0003] For example, some optical navigation devices have a higher frame refresh rate in image capture or higher precision in image processing. However, these optical navigation devices with high frame r...
