A recursive type-IV discrete cosine transform system includes a first permutation device, a recursive type-III discrete cosine/sine transform device, a cosine/sine factor generation device, a recursive type-II discrete cosine/sine transform device, a second permutation device. The first permutation device performs two-dimensional order permutation operation on N digital signals for generating N two-dimensional first temporal signals. The recursive type-III discrete cosine/sine transform device repeats a type-III discrete cosine/sine transform for generating second temporal signals. The cosine/sine factor generation device sequentially performs cosine/sine factor multiplication and corresponding addition operations for generating third temporal signals. The recursive type-II discrete cosine/sine transform device repeats a type-II discrete cosine/sine transform for generating fourth temporal signals. The second permutation device performs a one-dimensional order permutation operation for generating N one-dimensional output signals. The N one-dimensional output signals are obtained by performing a type-IV discrete cosine transform on the N digital input signals.

A method for executing a mouse function of electronic device and an electronic device thereof are provided. In the present method, an amount and a relative position of input signals are detected by a sensor module. Then, whether the amount and the relative position are respectively conformed to a predetermined value is determined. If the predetermined values are conformed, whether the input signal is conformed to a specific signal is determined when a variation of the relative position is occurred. Finally, a corresponding mouse function is executed according to a type of the variation if the variation is conformed to the specific signal. As a result, a mouse device is no longer needed for a user to accomplish a directional operation on the electronic device so as to prevent inconvenience of particularly carrying a mouse device.

A touch display device includes a main body, a detecting module and a touch display module. The detecting module includes a plurality of sensing elements for sensing a touch position of a user at the main body and providing a touch signal to the detecting module. The touch display module is disposed at the main body and electrically connected to the detecting module. The touch display device generates a function control zone corresponding to the touch position in accordance with the touch signal. A control method of a touch display device is disclosed as well. The touch display device and the control method can generate the function control zone corresponding to the touch position by sensing the touch of the user to replace physical hot keys.

A method for controlling a touch control module and an electronic device are provides. The electronic device includes a display and a host. The host includes a sensing module, a touch control module and a control unit. The sensing module includes a sensing unit for detecting the gesture and generating the corresponding sensing signal. The control unit determines whether the gesture complies with a preset condition according to the sensing signal. When the determining result is yes, the control unit controls the touch control module to enter the first control mode. On the contrary, if the determining result is no, the control unit controls the touch control module to enter the second control mode.

A method for operating a page and an electronic device are provided. In the method, touch signal is received first via a touch screen. Then, if the time for which the touch signal keeps at a location of the touch screen reaches a preset time is determined. If the time for which the touch signal keeps at the location reaches the preset time, a moving track formed by the touch signal is captured, and a page displayed on the touch screen is operated according to the type of the moving track. In the method, whether the touch signal of the user is responded depends on the time of the touch signal. Consequently, the inconvenience caused by unintentional touch can be avoided, and the user can achieve the operation of the page by simple touch signal.
