Abstract: A smart device having ability for rejecting mistaken touching is illustrated, which comprises a capacitive button module which comprises a contacting layer, a first electrode layer, a second electrode layer and an elastic layer. A first electrode of the first electrode layer and a second electrode of the second electrode layer form a first inductive capacitor, and the second electrode and a third electrode of the second electrode layer form a second inductive capacitor. When the elastic layer receives a pressure and generates a deformation, a pressing signal is generated according to a capacitance variation of the first inductive capacitor. When a conductor is close to or in contact with the contacting layer, a moving signal is generated according to a capacitance variation of the second inductive capacitor.

Abstract: An image determining method for scanning an image and determining specific image pixels of a specific image. The method comprises: determining at least one pixel in a first row having brightness value larger than a threshold value as the specific image pixel; defining a leftmost pixel and a rightmost pixel of the specific image pixel in the first row as a leftmost edge and a rightmost edge of a first specific image range; and defining a second specific image range in a second row of the image, which is next to the first row. Column positions of a leftmost edge and a rightmost edge of the second specific image range are respectively the same with column positions of the leftmost edge and the rightmost edge of the first specific image range. Via this method, the determining for the specific image pixels is more accurate.
