  • Patent number: 11669591
    Abstract: An information processing apparatus includes a processor configured to infer an object represented in image data to be processed, the object being inferred by using a learning model for inferring the object represented in the image data, and perform image processing on the image data with a correction level of the image processing for correcting the image data being varied on a basis of a probability of correctness in inference of the object.
    Type: Grant

  • Patent number: 10997749
    Abstract: An information processing apparatus includes a unit that obtains one or more pairs, each of which is constituted by images before and after correction, a unit that obtains changes in color, caused by the correction, of points in an image for the one or more pairs, a unit that obtains a distribution of the changes for the obtained pairs, and an extracting unit. When an interval having a frequency equal to or larger than a threshold determined for each interval exists at a distance of a tolerance width or more from an interval having a maximum frequency in the distribution, the extracting unit extracts, as learning data to learn a color change caused by the correction, the changes that are included in the interval having the maximum frequency but are not included in the interval having a frequency equal to or larger than the threshold determined for each interval.

  • Patent number: 10834370
    Abstract: An image processing apparatus includes an acceptance unit and a color conversion property creation unit. The acceptance unit accepts sets of image information each of which is composed of image information of an image before color conversion and image information of an image after color conversion. The color conversion property creation unit creates a color conversion property for color conversion of an image on the basis of pieces of image-capture setting information that are set for image-capture conditions used when the images before color conversion are captured.

  • Patent number: 9936182
    Abstract: An image generation apparatus includes an image-data generation unit, an image-data output unit, and a retaining unit. The image-data generation unit generates image data of an evaluation image having a first reference color, a second reference color, a first evaluation color, and a second evaluation color, the first and second reference colors being paired in a predetermined color space, the first and second evaluation colors being different colors between the first and second reference colors in the predetermined color space. The image-data output unit outputs the image data to a display device. The retaining unit retains image data of the first and second evaluation colors obtained when an image having the first evaluation color looks the same as an image having the second evaluation color in terms of brightness or tint in a case where the evaluation image is displayed on the display device.

  • Patent number: 9525857
    Abstract: A color processing device includes the following elements. An image data obtaining unit obtains image data which is obtained by imaging a white member illuminated by a light source and a display device on which a white image is displayed. A color component extracting unit extracts color components of red, green, and blue from image data concerning the white member and image data concerning the white image. A relation determining unit determines a relation between a color temperature and/or a brightness level of the light source and a color temperature and/or a brightness level of the white image, on the basis of a magnitude relation of the extracted color components.
