Abstract
An optical detecting device with a tracking function includes an image acquiring module and a processor. The image acquiring module is grouped into a first cluster and a second cluster of pixels. The first cluster and the second cluster are arranged adjacent to each other, and used to respectively acquire a first imaging result and a second imaging result both containing an indicating mark. The processor is electrically connected to the image acquiring module and adapted to track a proceeding direction of the indicating mark by computing difference between the first imaging result and the second imaging result. The optical detecting device further includes a memory module electrically connected to the processor, and the processor analyzes the computed difference via a lookup table stored inside the memory module to determine the proceeding direction.
