Abstract
A color conversion system includes: an image reader that reads a test sheet on which a plurality of patches is formed and outputs a read image; and a hardware processor that analyzes a region of interest for each of the patches of the read image according to an operation mode for a color conversion table in which a read pixel value and a pixel value in a color space are associated with each other for each of the patches of the read image, and performs image noise removal processing, and performs color conversion of converting the read pixel value corresponding to the region of interest of the patch into a pixel value in the color space using the color conversion table in a case where the operation mode is a use mode.
Claims12
A color conversion system comprising:
- an image reader;
- and
- a hardware processor that executes processes comprising:
- receiving a read image read by the image reader, the read image being an image of a test sheet having a plurality of patches formed thereon;
- determining an operation mode for a color conversion table in which a read pixel value and a pixel value in a color space are associated with each other for each of the patches;
- analyzing, in the read image, a region of interest for each of the patches of the read image according to the operation mode;
- and
- performing image noise removal processing,
- wherein, in a case where the operation mode is a use mode, the hardware processor performs color conversion by converting a read pixel value corresponding to the region of interest in the read image into a pixel value in the color space using the color conversion table.
A color conversion method comprising:
- acquiring a read image read by an image reader, the read image being an image of a test sheet having a plurality of patches formed thereon;
- acquiring a colorimetric value of the test sheet;
- determining an operation mode for a color conversion table in which a read pixel value and a pixel value in a color space are associated with each other for each of the patches;
- analyzing, in the read image, a region of interest for each of the patches of the read image according to the operation mode;
- and
- performing image noise removal processing,
- wherein, in a case where the operation mode is a use mode, the method comprises performing color conversion by converting a read pixel value corresponding to the region of interest in the read image into a pixel value in the color space using the color conversion table.
An information processing apparatus comprising a hardware processor that executes processes comprising:
- acquiring a read image read by an image reader, the read image being an image of a test sheet having a plurality of patches formed thereon;
- acquiring a colorimetric value of the test sheet;
- analyzing, in the read image, a region of interest for each of the patches of the read image according to the operation mode;
- and
- performing image noise removal processing,
- wherein, in a case where the operation mode is a use mode, the hardware processor performs color conversion of converting the read pixel value corresponding to the region of interest of the patch into a pixel value in the color space using the color conversion table in a case where the operation mode is a use mode.
