    • In a misregister amount detection method, printed register marks of colors are sensed, and the inverted R, G, and B image data of R, G, and B image data respectively containing R, G, and B as red, green, and blue color components of the register marks are extracted. The minimum value of the pixel values of corresponding pixels of the generated inverted R, G, and B image data is extracted and converted into the pixel value of a corresponding pixel of K image data containing K as a black color component. Differential R, G, and B image data are obtained by subtracting the pixel value of each pixel of the K image data from the pixel values of corresponding pixels of the inverted R, G, and B image data. Enhanced R, G, and B image data are obtained by adding the pixel values of pixels of the differential R, G, and B image data or values corresponding to the pixel values to the pixel values of corresponding pixels of the inverted R, G, and B image data. The misregister amount between the colors is obtained on the basis of the pixel values of pixels of the enhanced R, G, and B image data. A misregister amount detection apparatus is also disclosed.
    • 在不对准量检测方法中,检测印刷的颜色对准标记,并且分别包含R,G和B的R,G和B图像数据的反转R,G和B图像数据分别为红色,绿色和蓝色 提取对齐标记的颜色分量。 提取生成的反相R,G和B图像数据的相应像素的像素值的最小值,并将其转换成包含K的K个图像数据的相应像素的像素值作为黑色分量。 通过从反转的R,G和B图像数据的相应像素的像素值中减去K个图像数据的每个像素的像素值,获得差分R,G和B图像数据。 通过将差分R,G和B图像数据的像素的像素值或对应于像素值的值相加到反相R,G和B的相应像素的像素值,获得增强的R,G和B图像数据, 和B图像数据。 基于增强的R,G和B图像数据的像素的像素值获得颜色之间的不对准量。 还公开了不对准量检测装置。
