    • An image processing system including a plurality of pen-like input units 31 which produce signals of frequencies inherent to the respective input units, a panel 32 responsive to a touch of the input unit 31 thereto for detecting its touch position and produced signal frequency, an image processor 5 which performs a predetermined image processing operation depending on signals indicative of the touch position and frequency from the panel 32, and a display 7 which displays the result of the image processing by the image processor 5. The respective frequencies determine corresponding color information used. The image processor 5 performs an image processing operation on the basis of the determined color information. Even when a card is used, page detection is performed in an optically non-contact manner, using a simple structure.
    • 一种图像处理系统,包括产生各个输入单元固有的频率信号的多个笔状输入单元31,响应于其输入单元31的触摸以检测其触摸位置和产生的信号频率的面板32, 图像处理器5,其根据指示来自面板32的触摸位置和频率的信号执行预定的图像处理操作;以及显示器7,显示由图像处理器5进行的图像处理的结果。各个频率确定相应的颜色信息 用过的。 图像处理器5基于所确定的颜色信息执行图像处理操作。 即使使用卡,也可以使用简单的结构,以光学非接触的方式进行页面检测。
