摘要： A method and apparatus for generating a white signal component and for controlling the brightness of an image are provided. In the above method and apparatus, the brightness increases of Red, Green and Blue, the saturations of which are not decreased from an input image are calculated using a vector, and the minimum value of such increases is utilized as the input value for the white component. Further, by adding brightness control components of RGB color to the input RGB signals, brightness increases in the direction of the original colors instead of the achromatic one are possible, which is the way the white component is added so as to increase the luminance of color display devices representing a color using a color filter such a flat panel display. Accordingly, a color saturation of the image is not decreased even with addition of the achromatic color a component. In other words, in converting a signal from the three colors such as RGB into the four colors inclusive of white component, the present invention is capable of increasing the brightness without reduction of saturation as well as extracting the white component in an easy and efficient way, which enhances the performance of image processing apparatuses such as color display devices and the like.
摘要翻译：提供了一种用于产生白色信号分量并用于控制图像的亮度的方法和装置。在上述方法和装置中，红色，绿色和蓝色的亮度增加使用向量计算其输入图像的饱和度不降低，并且这种增加的最小值被用作白色的输入值零件。此外，通过向输入的RGB信号添加RGB颜色的亮度控制分量，可以在原色方向上增加亮度而不是消色差，这是添加白色分量以增加颜色亮度的方式使用诸如平板显示器的滤色器表示颜色的显示设备。因此，即使添加无色成分，也不会降低图像的色彩饱和度。换句话说，在将诸如RGB的三种颜色的信号转换为包括白色分量的四种颜色的情况下，本发明能够在不降低饱和度的同时提高亮度以及以简单有效的方式提取白色分量，这增强了诸如彩色显示装置等的图像处理装置的性能。
