    The physical meaning and Boolean logical mathematical model of color information are described in this paper. The digital code for color information is presented in this paper. This code is both intuitive and simple. Therefore, it is useful, among other things, to analyse logical features of color information, and to study the application of Boolean algebra to color information processing. To some extent synthesis and analysis of color information may be bandied by the color code and the design operation traction....

    The physical meaning and Boolean logical mathematical model of color information are described in this paper. The digital code for color information is presented in this paper. This code is both intuitive and simple. Therefore, it is useful, among other things, to analyse logical features of color information, and to study the application of Boolean algebra to color information processing. To some extent synthesis and analysis of color information may be bandied by the color code and the design operation traction. The logical analysis and the aberration computation of the color picture are discussed in detail.

    为了实现彩色信息的有效获取、大容量存贮、快速传输和高效率编码调制与解调应用,本文探讨了布尔逻辑在此领域的具体应用与分析方法。从而总结出光束叠加混色与颜料混合混色之间的“对称”逻辑关系,并给出了不同色彩的数字编码。上述规律反映在数码运算上则是很简单的“反码”关系,据此只需一般数码的加、减法运算即可正确表达不同色彩的混色规律(即Grassman定律)。应用本文所获结果再经色别/数字与数字/色别变换,可进一步探讨实现彩色信息的数字存贮、传输与显示。本文所获结果尚表明:布尔逻辑分析方法除传统应用于脉冲数字电路外,亦可有效地应用于光学系统,但本文仅限于初步的理论探讨。
