摘要:
A color reproducing system includes a color image input section. A color image processing device has an image processing section for performing a predetermined processing on color image data input through the color image input section. A storage section stores therein the color image data which has been input through the color image input section. A color image output section outputs the color image data which has been stored in the storage section. The color image processing device further includes a processing selection section for performing selection about whether or not the predetermined processing is performed on the color image data input through the color image input section.
摘要:
A spectrum and color reproduction system has a multi-band camera (1), a six-primary-color display (3), and an image converting device (2) which converts a 16-band photographing signal from the multi-band camera (1) into a 6-primary-color display signal of the six-primary-color display (3) by using an input profile of the multi-band camera (1) and an output profile and a color spatial converting profile of the six-primary-color display (3). The input profile and the output profile have information on a corresponding relationship between the respective color signals and one of a spectrum and a spectral reflectance, and the color spatial converting profile has one of a color matching function and an illumination-light spectrum which prescribes a reflection spectrum for the spectral reflectance.

A color reproduction system has a color image input section, and a color correcting section for correcting colors of a subject image obtained by photographing a subject by the color image input section. The color correcting section corrects colors by changing over a plurality of color correction parameters according to a subject image signal from the color image input section.
摘要:
This invention includes an RGB color camera for photographing an object under photographing illumination light, a simplified spectrophotometer for measuring a photographing illumination light spectrum, and a color correction device for calculating tristimulus value data of the object and converting the data into an input signal to a CRT monitor by using monitor profile data. On the observation side, a CRT monitor and illumination light colorimeter for measuring the tristimulus values of observation illumination light are arranged. A color correction device can perform color reproduction without being influenced by changes in the color perception characteristics of a person such as chromatic adaptation by reproducing a virtual illumination light spectrum having tristimulus values equal to those of the observation illumination light without measuring any observation illumination light spectrum.

A color reproduction system includes a color image display unit capable of displaying a color image of four or more primary colors, and a color converting unit for converting input three-primary color signals into color image signals of respective primary colors of the color image display unit. The color converting unit includes an area deciding section that decides a color conversion area to which the input three-primary color signals belong in a three-dimensional color space, and a color image signal calculating section that converts the input three-primary color signals into color image signals of respective primary colors based on color conversion parameters corresponding to a color conversion area decided by the area deciding section.
摘要:
An image forming apparatus has a recording head consisting of a plurality of recording elements for forming an image on a recording medium on the basis of given image data. A density irregularity characteristics data generating section generates density irregularity characteristics data on the basis of density irregularity data of a pattern generated with use of the recording head, and a plurality of attribute data used for generating the pattern. A density irregularity correction section corrects image data by using the density irregularity characteristics data generated in the density irregularity characteristics data generating section.
