This topic is carries on the optimized design to the existing offset press Automatic Register Control System, enhances to the low color difference signal recognition and the judgment, thus enhances the system the sensitivity and the precision. 本课题是对现有的彩色凹印机自动套准系统进行优化设计,提高对低色差信号的识别和判断,从而提高系统的灵敏度和精确度。
However, color difference signal is not as intuitive as hue and saturation. According to the definition of chroma diagram, the paper presented a generalized calculation program of three factors by analyzing the calculation method of colorama's chroma parameter. 但是色差信号物理含义不如色度参数中的色调和饱和度直观,为此,依据色度图定义,本文通过分析彩色光的色度参数计算方法,建立了一个通用的3要素计算程序。
