first embodiment

[0030]FIG. 1 is a schematic view of a sensing system according to a first embodiment of the present invention. Referring to FIG. 1, the sensing system 200 of the embodiment includes a panel 210, a first image sensor 220, a second image sensor 230 and a processor 240. The panel 210 has a surface 214 and an area 212, and the area 212 is located at the surface 214. The area 212 is a quadrilateral for example. The first image sensor 220 and the second image sensor 230 are disposed at the surface 214 of the panel 210 and are electrically connected to the processor 240. A sensing range of the first image sensor 220 and a sensing range of the second image sensor 230 cover the area 212, respectively. In this embodiment, the panel 210 is a whiteboard or a touch screen for example.

[0031]When a user uses an object 20 which is capable of being sensed by the sensing system 200 such that the object 20 approaches the area 212, the first image sensor 220 and the second image sensor 230 sense the ar...

second embodiment

[0053]FIG. 6 is a schematic view of a sensing system according to a second embodiment of the present invention. The sensing system 300 includes a panel 310, an image sensor 320, a reflective mirror element 330 and a processor340. The image sensor 320 is disposed at the panel 310. The reflective mirror element 330 is disposed at the panel 310 and a reflective mirror plane 332 of the reflective mirror element 330 mirrors a first area 312 of the panel 312 for forming a second area 312′. The image sensor 320 faces the reflective mirror element 330 and is electrically connected to the processor 340. A sensing range of the image sensor 320 covers the first area 312 and the second area 312′. That is, the second image sensor 230 of the first embodiment is omitted in the sensing system 300 of this embodiment and the reflective mirror element 330 is added in the sensing system 300 of this embodiment.

Abstract

A controlling method applied to a sensing system includes the following step. Whether a specific function is started is determined according to the amount of pixels of a first total pattern acquired by sensing a first object. In an embodiment of the present invention, the step of determining whether the specific function is started according to the amount of pixels of the total pattern is the step of determining whether the specific function is started according to the amount of pixels of the total pattern and the length of time to successively acquire the total pattern. Accordingly, it is more convenient for a user to use the sensing system having the said controlling method.

Description

CROSS-REFERENCES[0001]This is a division of an application Ser. No. 12 / 557,466, filed Sep. 10, 2009 which is based upon and claims the benefit of priority from a Taiwan application No. 098116457 filed on May 18, 2009. The entirety of the above-mentioned patent applications are hereby incorporated by reference herein and made a part of this specification.BACKGROUND[0002]1. Field of the Invention[0003]The present invention relates to a controlling method and in particular, to a controlling method applied to a sensing system.[0004]2. Description of the Prior Art[0005]A conventional sensing system includes a panel, two image sensors, and a processor. Each of the image sensors senses an area of the panel for acquiring an image, and the processor successively processes for calculating a position of a pointer on the area.
