  • 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.

    Abstract: An image processing apparatus includes a reception unit and a conversion unit. The reception unit receives as a designated color a color of an image desired to be seeable when irradiated with light at a specific wavelength. The conversion unit converts, when converting image data on an image to be printed into print data, a color value of the designated color received by the reception unit into a color value including a value for outputting a special color material that has absorption properties for the light at the specific wavelength.

  • Publication number: 20200123500
    Abstract: The invention relates to a method of producing a retinal pigment epithelial cell from a human pluripotent stem cell, and a method of treating or preventing a retinal disease by using the produced cell. The retinal pigment epithelial cell is prepared by (a) inducing differentiation of a human pluripotent stem cell into a pigment cell by adhesion cultivation of a human pluripotent stem cell in a medium containing a Nodal signal inhibitor and a Wnt signal inhibitor in the absence of a feeder cell to give a culture containing the pigment cell, (b) subjecting the obtained culture to further adhesion culture to give a culture containing a pigment cell colony, and (c) isolating the pigment cell from the obtained culture and culturing the cell to give a retinal pigment epithelial cell.
