    • An optical touch system includes a substrate, a glass module, two light sources, three reflective clothes, two image sensors and a processing module. The glass module is disposed at one side of the substrate. The two light sources are respectively disposed at two terminals of the glass module. The three reflective clothes are disposed on the edges of the substrate contiguously. A touch region is formed among the three reflective clothes and the glass module for reflecting the light emitted from the two light sources. The two image sensors are disposed respectively next to the two light sources and used for capturing images in the touch region. The processing module is used for determining whether a touch action is performed according to the images in the touch region.
    • 光学触摸系统包括基板,玻璃模块,两个光源,三个反射衣服,两个图像传感器和一个处理模块。 玻璃模块设置在基板的一侧。 两个光源分别设置在玻璃模块的两个端子处。 三个反光衣服相邻地设置在基板的边缘上。 在三个反射衣物和玻璃模块之间形成用于反射从两个光源发射的光的触摸区域。 两个图像传感器分别设置在两个光源的旁边,并用于捕获触摸区域中的图像。 处理模块用于根据触摸区域中的图像确定是否执行触摸动作。

    • The invention discloses an image processing apparatus for adjusting the saturation of an input image. The input image also has a lightness and a hue. The image processing apparatus includes a look-up table, a processing unit, and a multiplier. The look-up table is used for recording M lightness ranges, N hue ranges, and M*N corresponding gains. The processing unit is used for storing the look-up table and, according to the look-up table, for judging that the lightness of the input image is located in which lightness range, and the hue is located in which hue range, so as to determine a corresponding gain from the gains. The multiplier is coupled to the processing unit and used for multiplying the saturation of the input image by the corresponding gain. Accordingly, the image quality is improved.
    • 本发明公开了一种用于调整输入图像的饱和度的图像处理装置。 输入图像也具有亮度和色调。 图像处理装置包括查找表,处理单元和乘法器。 查找表用于记录M个亮度范围,N个色调范围和M * N个相应的增益。 处理单元用于存储查找表,并且根据查找表,用于判断输入图像的亮度位于哪个亮度范围内,并且色调位于哪个色相范围内,以便 从收益中确定相应的收益。 乘法器耦合到处理单元并用于将输入图像的饱和度乘以相应的增益。 因此,提高了图像质量。
