    • The present invention enables to easily perform a graphic processing even when a touch panel is used. When a resistance film unit is pressed with a pen or a finger, output voltages associated with the X coordinate and the Y coordinate position are changed and these output voltages are transmitted as the X coordinate data and the Y coordinate data to a touch panel driver. According to the output from the resistance film unit, the touch panel driver generates an event for supply to a GUI handler. The touch panel driver includes a two-point specification detector which detects two point specifications and causes to calculate coordinates of the two points. The GUI handler generates a message corresponding to the GUI according to the event and supplies the message to an application. The GUI handler includes a processing mode modification block which differently interprets the event when a single point is specified and when two points are specified, thereby modifying the graphic processing mode.
    • 即使使用触摸面板,本发明也能够容易地进行图形处理。 当用笔或手指按压电阻胶片单元时,改变与X坐标和Y坐标位置相关联的输出电压,并将这些输出电压作为X坐标数据和Y坐标数据发送到触摸面板驱动器。 根据来自电阻胶片单元的输出,触摸面板驱动器产生用于供应给GUI处理程序的事件。 触摸屏驱动器包括两点规格检测器,其检测两点规格并导致计算两点的坐标。 GUI处理程序根据事件生成对应于GUI的消息,并将消息提供给应用程序。 GUI处理器包括处理模式修改块,当指定单个点时以及当指定了两个点时不同地解释事件,从而修改图形处理模式。
