Optical touch control apparatus and adjustable light guide apparatus |
| 摘要 |
An optical touch control apparatus, for detecting displacement between an object and the optical touch control apparatus. The optical touch control apparatus comprises: an object detecting apparatus, for detecting the object to generate an object image, having a first detecting area in a first mode and having a second detecting area in a second mode, wherein the first detecting area is larger than the second detecting area; an image sensor, for capturing at least one frame of the object image; and a control unit, for adjusting an image capturing area of the image sensor, according which one of the first detecting area and the second detecting area the object detecting apparatus utilizes. |
