摘要： Provided is an optical navigation device and a method of operating the same. The optical navigation device includes: a light source for irradiating light; an image sensor for collecting incident light to obtain an image; and a controller for performing a calculation mode that obtains an image when the light source is ON to calculate a movement value and determines whether the optical navigation device is moved on the basis of the movement value, a sleeping mode that turns OFF the light source and stops an operation of the image sensor, and a detection mode that obtains the image when the light source is ON and an image when the light source is OFF and then compares characteristics of the images to determine whether the optical navigation device is separated from the work surface, wherein the controller performs the calculation mode when the optical navigation device is moved and not separated from the work surface, performs the sleeping mode when not moved and separated from the work surface, and periodically performs the detection mode. Therefore, it is possible to precisely detect whether the optical navigation device is spaced apart from a work surface to prevent malfunction and unnecessary power consumption of the optical navigation device due to separation from the work surface.

摘要： An optical position tracking device and a method of testing the same are provided. The device includes: a controller for generating at least one test operation signal in response to a command signal; a test signal generator for generating a test signal during a test operation in response to the test operation signal; a motion calculator for receiving the test signal during the test operation and performing operations in response to the test operation signal to output an output signal; and an output signal analyzer for determining whether the output signal is correct during the test operation in response to the test operation signal to output a result signal. Thus, the complexity of the method of testing the optical position tracking device can be markedly reduced and it is unnecessary to employ a high-performance test apparatus. Further, the time taken to test the optical position tracking device can be shortened by simplifying and optimizing test circumstances, and a test can be performed by connecting the optical position tracking device with a typical system, such as a personal computer (PC), instead of exclusively employing a test apparatus.
