Abstract
An image processing apparatus includes an acquisition unit configured to acquire a reference image serving as a reference printing result and a target image serving as a printing result to be inspected, a correction unit configured to correct the target image based on a paper white area of each of the reference image and the target image so that a paper white color of the paper white area of the target image matches a paper white color of the paper white area of the reference image, wherein the paper white area is determined based on a positional displacement between the reference image and the target image, and an inspection unit configured to inspect the printing result by comparing the corrected target image with the reference image.
Claims11
An image processing apparatus comprising:
- an acquisition unit configured to acquire a reference image serving as a reference printing result and a target image serving as a printing result to be inspected;
- a correction unit configured to correct the target image based on a paper white area of each of the reference image and the target image so that a paper white color of the paper white area of the target image matches a paper white color of the paper white area of the reference image, wherein the paper white area is determined based on a positional displacement between the reference image and the target image;
- and
- an inspection unit configured to inspect the printing result by comparing the corrected target image with the reference image.
A non-transitory computer-readable storage medium storing a program for causing a computer to perform an image processing method comprising:
- acquiring a reference image serving as a reference printing result and a target image serving as a printing result to be inspected;
- correcting the target image based on a paper white area of each of the reference image and the target image so that a paper white color of the paper white area of the target image matches a paper white color of the paper white area of the reference image, wherein the paper white area is determined based on a positional displacement between the reference image and the target image;
- and
- inspecting the printing result by comparing the corrected target image with the reference image.
