Abstract:
1. An optical imaging system capable of detecting a moving direction of an object, and the optical imaging system comprising: a display panel, whereon a coordinate detecting area is formed; a light source module disposed on an outer side of the display panel and for emitting light; a touch object comprising at least one reflective section for reflecting the light emitted from the light source module as moving in the coordinate detecting area, and the touch objects moving from a first position at a first time to a second position at a second time; a first image sensor disposed on an outer corner of the display panel and for capturing light reflected from the at least one reflective section so as to respectively generate a first signal at the first time and a second signal at the second time corresponding to the touch object; a second image sensor disposed on another outer corner of the display module and for capturing light reflected from the at least one reflective section so as to respectively generate a third signal at the first time and a fourth signal at the second time corresponding to the touch object; and a control module coupled to the first image sensor and the second image sensor, and the control module being for computing a moving direction of the touch object from the first position to the second position according to variation of the first signal, the second signal, the third signal and the fourth signal.
