  • Patent number: 11948282
    Abstract: An image processing apparatus generates a normal image, when lighting correction of an image is performed using three-dimensional shape data. Three-dimensional shape data of a predetermined object is adjusted with a subject in position, based on a feature pattern detected in image data, and lighting processing for correcting a pixel value of the image data is performed based on the adjusted three-dimensional shape data, distance information of the subject, and a position of a virtual light source. When the three-dimensional shape data is adjusted with the image data in position, a region having a large irregularity in the three-dimensional shape data is preferentially adjusted in position.

  • Publication number: 20240054668
    Abstract: An object is to obtain three-dimensional shape data with high accuracy from three-dimensional shape data representing an approximate shape of an object. Three-dimensional shape data of an object captured in a plurality of captured images whose viewpoints are different is obtained. Further, surface three-dimensional information on the object is derived based on the plurality of captured images. Then, the derived surface three-dimensional information is selected based on a distance from the shape surface of the object represented by the three-dimensional shape data.

  • Publication number: 20240005478
    Abstract: A detection sensitivity is set such that a detection sensitivity for a defect corresponding to a predetermined local pattern in a reference image, which is a reference printing result, is lower than for a region other than the predetermined local pattern in the reference image. Image data representing an image of an inspection target is acquired and the image of the inspection target is inspected based on the reference image and the set detection sensitivity.

  • Publication number: 20230351584
    Abstract: An image processing apparatus is provided. First information indicating a local displacement between a first document image and a first read image is obtained. The first read image is obtained by reading a print product based on the first document image. A reference image is generated. The reference image is obtained by adding the local displacement in accordance with the first information to a second document image. A second read image and the reference image is compared with each other to perform an inspection of a print product based on the second document image. The second read image is obtained by reading the print product based on the second document image.

  • Patent number: 11710343
    Abstract: The image processing unit selects multiple subject areas from strobe-ON image data to be corrected, and, from the selected multiple subject areas, the image processing unit acquires a feature amount such as gloss information corresponding to each subject. Subsequently, from each subject area, the image processing unit selects a part of the subject area, based on the acquired feature amount. Then, regarding the partial area of each subject area, which is selected based on the feature amount, the image processing unit estimates the auxiliary light arrival rate corresponding to each subject, based on a pixel value of the strobe-ON image data and a pixel value of strobe-OFF image data. Thereafter, based on the estimated auxiliary light arrival rate, the image processing unit corrects the brightness of each subject area of the strobe-ON image data, in order to generate corrected image data.
