Control device and inspection device

A control device that controls a printed material processing device to process a printed material, the control device comprising:

• a capturing unit that captures an inspection target object printed on the printed material, and outputs RGB values of each pixel of a captured image;
• a converter that specifies a pixel with respectively equal RGB values and a pixel with respectively approximating RGB values in the image captured by the capturing unit as pixels in a grayscale area, and converts the RGB values of each pixel other than the grayscale area into HSV values in an HSV color space;
• an extractor that extracts a pixel of an extraction target color from the image captured by the capturing unit based on the RGB values in a case of the pixel in the grayscale area, and based on the HSV values in a case of the pixel other than the grayscale area;
• and
• a controller that controls the printed material processing device to adjust a processing position of the printed material based on the pixel of the extraction target color extracted by the extractor.

An inspection device that inspect a printed material comprising:

• a capturing unit that captures an inspection target object printed on the printed material, and outputs RGB values of each pixel of a captured image;
• a converter that specifies a pixel with respectively equal RGB values and a pixel with respectively approximating RGB values in the image captured by the capturing unit as pixels in a grayscale area, and converts the RGB values of each pixel other than the grayscale area into HSV values in an HSV color space;
• an extractor that extracts a pixel of an extraction target color from the image captured by the capturing unit based on the RGB values in a case of the pixel in the grayscale area, and based on the HSV values in a case of the pixel other than the grayscale area;
• and
• a comparator that compares the image of the inspection target object and a reference image based on the pixel of the extraction target color extracted by the extractor.
