CONTROL DEVICE AND INSPECTION DEVICE
20200005104 · 2020-01-02 ·

In a control device which controls a printing press, a capturing unit captures an inspection target object printed on a target printed material by the printing press, and outputs RGB values of each pixel of a captured image. The converter specifies a pixel with respectively equal RGB values and a pixel with respectively approximating RGB values as pixels in the grayscale area in the image, and converts the RGB values of each pixel other than the grayscale area into HSV values. An extractor extracts a pixel of an extraction target color from the image based on the RGB values in a case of the pixel in the grayscale area, and the HSV values in a case of the pixel other than the grayscale area. The controller controls the printing press to correct the print misalignment based on the pixels of the extraction target color extracted by the extractor.
