Claim One:
1. A controlling method applied to a sensing system, the sensing system comprising a panel, a first image sensor and a second image sensor; the first image sensor and the second image sensor being disposed at the panel, a sensing range of the first image sensor and a sensing range of the second image sensor respectively covering an area of the panel where the first object located in, the controlling method comprising: (a) the first image sensor and the second image sensor simultaneously sensing the area for respectively acquiring a first image and a second image, wherein the first image comprises a first sub-pattern, the second image comprises a second sub-pattern, the first sub-pattern and the second sub-pattern correspond at that time to the first object, and the first total pattern is composed of the first sub-pattern and the second sub-pattern; (b) determining whether the amount of pixels of the first total pattern is greater than or equal to a first predetermined value; (c) further determining whether the length of time to successively acquire the first total pattern is greater than or equal to a second predetermined value if the amount of pixels of the first total pattern is greater than or equal to the first predetermined value; (d) starting the specific function if the length of time to successively acquire the first total pattern is greater than or equal to the second predetermined value; (e) the first image sensor and the second image sensor simultaneously sensing the area where the first object and a second object located in for respectively acquiring a third image and a fourth image, wherein the third image comprises a third sub-pattern, the fourth image comprises a fourth sub-pattern, the third sub-pattern and the fourth sub-pattern correspond at that time to the second object, and a second total pattern is composed of the third sub-pattern and the fourth sub-pattern; (f) determining whether the amount of pixels of the second total pattern is smaller than the first predetermined value; (g) further determining whether the length of time to successively acquire the second total pattern is greater than or equal to the second predetermined value if the amount of pixels of the second total pattern is smaller than the first predetermined value; and (h) ending the specific function if the length of time to successively acquire the second total pattern is greater than or equal to the second predetermined value.
