Abstract: A tincture adjustment value used to adjust a monochrome signal to a tincture desired by a user is set, and a tincture conversion table and chromaticity line table are generated based on that tincture adjustment value and the profile of an image output apparatus. Using the generated tables, a lightness signal L* corresponding to an input monochrome signal is converted into a distance signal l on a chromaticity line, and the distance signal l is converted into a chromaticity signal (a*, b*). The lightness signal L* and chromaticity signal (a*, b*) are converted into a color signal of the image output apparatus.

Abstract: PROBLEM TO BE SOLVED: To provide a device and method for processing an image and an image processing system with which stable color processing in an image input/ output device can be achieved by evaluating whether a profile about the image input/output device is appropriate or not. SOLUTION: In this method of controlling an image processing device, color conversion is performed based on a profile of a connected image input/output device. The method comprises a first acquisition step for acquiring a current characteristic indicating a current color reproducibility of the image input/output device, a second acquisition step for acquiring an estimated characteristic indicating a color reproducibility based on the profile of the image input/output device, a third acquisition step for acquiring stability of color reproducibility in the image input/output device, and an evaluation step for evaluating based on the current characteristic, the estimated characteristic and the stability whether the profile appropriately reflects the current characteristic.

Abstract: PROBLEM TO BE SOLVED: To solve the problem that conventionally when a profile concerning an image output apparatus is formed and when CMS using the profile is executed, proper color reproducibility as a CMS execution result cannot be obtained, if color reproducibility in the apparatus changes. SOLUTION: In a step S103, an irregularity estimating index U, showing stability of color reproducibility in the image output apparatus, is calculated. In a step S105, number n of samples for forming the profile in the apparatus is calculated on the basis of the index U. In steps S107, S108, n-number of measured color values in a test image are obtained. In a step S110, the mean value of the n-number for the measured color values is calculated, and the profile concerning the apparatus is formed on the basis of the mean value.

Abstract: PROBLEM TO BE SOLVED: To solve a problem that the appearance of a display image is made different from that of the image under a standard illumination by the influence of tube surface reflection when displaying a color image under an observation illumination on a display. SOLUTION: An equal color space converting part 101 converts an inputted chrominance signal to a signal value on a visually equal color space, a gamut mapping part 102 maps the signal value on the equal color space to the color reproducing range of a display 104 under the observation environment, and a display simulation part 103 converts the mapped chrominance signal to a signal for display to a display 104 on the basis of a parameter showing the influence of the tube surface reflection of the display 104 under the observation environment. Thus, display is enabled while considering the influence of tube surface reflection under the observation illumination of the display 104, and appearance equal with that under the standard illumination can be provided.

Abstract: PROBLEM TO BE SOLVED: To provide an image processing method and an image processor that can convert generated image data, on the basis of a display image of a display device under an observation environment into image data in compliance with a standard color space. SOLUTION: A display simulation section 101 converts the color signal of a received image into a signal on a uniform color space, on the basis of a parameter denoting the effect of reflection in a tube screen of a display device 104, under the observation environment, in order to convert image data generated on the basis of a display image on the display device 104 under the observation environment into image data on a standard color space, a gamut-mapping section 102 maps the color signal on the uniform color space with a color reproduction range of the standard color space from the color reproduction range of the display device 104 under the observation environment and a color signal conversion section 103 converts the color signal mapped on the uniform color space into a signal on the standard color space.

Abstract: PROBLEM TO BE SOLVED: To provide an image processing apparatus and method which always keep the view of a color under an observing condition prescribed to be constant concerning a visible image outputted, based on the same image data. SOLUTION: In order to measure the color of a sample under the prescribed observing condition and in a prescribed observing direction, an image observing device is constructed (S201) and a print obtained by outputting grid point data in a device color space is installed at an observing device for color measuring (S203 to S205) to store the result of color measuring in a profile (S206). Thus, color conversion based on a measured color value under an actual observing condition and in the observing direction is realized, and the picture data of the same value is observed always as a similar color under the actual observing condition and in the observing direction.
