Abstract: A controlling method for a sensing system includes the following step. Whether a specific function is started is determined according to the amount of pixels of a 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.

Abstract: A distance-measuring device is utilized for measuring a measured distance between a measured object and the distance-measuring device. The distance-measuring device reduces the effect of a background light and a flicking light by removing the part corresponding to the background light and the flicking light from light-sensed signals generated by an image sensor of the distance-measuring device. In addition, the distance-measuring device calculates a calibrating parameter for calibrating an assemble-error angle of the distance-measuring device, according to an imaging location of a reflective light obtained by measuring a calibrating object with a predetermined distance. In this way, the distance-measuring device can correctly calculate out the measured distance.
