  • IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD
    Publication number: 20150110398
    Abstract: Provided is an image processing apparatus capable of adjusting a color of an image of an observation target depending on differences between viewing angles. The image processing apparatus obtains a viewing angle of a first observation target and a viewing angle of a second observation target, and then corrects the color of each observation target by using the obtained viewing angles of the first and second observation targets.

  • Color processing apparatus and method thereof
    Patent number: 9001328
    Abstract: A sample information input unit obtains spectral reflectances of color patches formed on a medium from a measuring device or storage unit. A media characteristic input unit inputs bi-spectral radiance factors of the medium from the storage unit. A computing unit computes bi-spectral radiance factors of the color patches based on the spectral reflectances of the color patches obtained by the sample information input unit and the bi-spectral radiance factors of the medium input by the media characteristic input unit.
