    摘要: Estimating the spectral distribution of an object requires not only the time of image sensing by a multi-spectrum camera but also, in order to process all band information acquired, large amounts of memories for storing all the band information of all pixels, and the processing time for processing all the band information. In this invention, when the spectral distribution data of a total wavelength region is to be estimated from color data and a plurality of spectral distribution data different in wavelength region, the color data is acquired, and, on the basis of the configuration of spectral distribution data defined in accordance with the acquired color data, spectral distribution data necessary for the estimation is acquired. In this way, the spectral distribution data of the total wavelength region is estimated.

    摘要: When a whole input gamut is mapped into an output gamut, even a gamut range which is not used in practice is mapped into the output gamut. This causes a saturation drop or tone loss. In order to solve this problem, image data obtained by the first device is input and an obtaining condition of the input image data is obtained. On the basis of the obtaining condition, the first gamut information of the input image data is obtained from a table showing the relationship between the output gamut of the first device and the obtaining condition. On the basis of the first gamut information and the second gamut information which indicates the gamut of the second device, the input image data is mapped into the gamut indicated by the second gamut information.

    摘要: It is desired to adopt gamut mapping using a color appearance space in the processing system of an ICC profile. Upon generating an LUT complying with the ICC profile format, a grid point outside of the visible region on the CIELAB space is moved into the visible region. The Lab values of the grid point are converted into XYZ values, which undergo color appearance conversion to acquire color appearance values. The acquired color appearance values are mapped on the color gamut of a predetermined device.
