颜色信号处理装置及方法、颜色转换装置及方法
摘要：
本发明公开了一种颜色信号处理装置及方法和颜色转换装置及方法，所述颜色信号处理装置包括总量计算单元、限制值计算单元以及校正单元。所述总量计算单元计算将输出装置中所用的色材的各颜色作为颜色成分的输出装置颜色空间中的输入颜色信号的总量值。所述限制值计算单元根据所计算出的总量值来计算用于限制颜色信号的总量的限制值。所述校正单元校正所述输出装置颜色空间中的所述输入颜色信号以使所述输入颜色信号的总量值等于或小于所计算出的限制值。
摘要（英）：

The invention discloses a color signal processing apparatus and a method, and a color conversion apparatus and a method. The color signal processing apparatus includes a total amount calculating unit, a limit value calculating unit and a correcting unit. The total amount calculating unit calculates a total amount value of an input color signal in an output device color space which has, as color components, colors of coloring materials used in an output device. The limit value calculating unit calculates a limit value for limiting a total amount of a color signal, in accordance with the calculated total amount value. The correcting unit corrects the input color signal in the output device color space so that the total amount value of the input color signal becomes the calculated limit value or less.
