摘要： PROBLEM TO BE SOLVED: To enable color transformation for providing a reproduced image improved in a color tone by transforming color data expressing a first coordinate point to color data expressing a second coordinate point in a color transforming process according to a color transformation algorithm corresponding to the degree of coloring in the color expressed at the first coordinate point. SOLUTION: It is possible for color data expressing a coordinate point inside a color expression area 103 mapped in the output RGB space of a color scanner to express the coordinate point out of the color expression area of a color printer. Theses color data are defined as first color data. After an evaluation value indexing the degree of coloring in the color expressed by the first color data mapped in the output RGB space is found, the first color data, for which it is possible to be protruded from the color expression area of the color printer, to be mapped in the output RGB space are transformed to color data (second color data) expressing the coordinate point for guaranteeing a coordinate point inside the color expression area of the color printer.

摘要： PROBLEM TO BE SOLVED: To scroll an object to be observed which is displayed on a displaying medium such as a display without giving an observer a visual load. SOLUTION: Data S read from media 2 are shown on a display 1 and the displayed position is set as a reference position. The movement of a display device 7 is detected by a sensor 4, and a scroll operating part 6 calculates the scroll quantity of an object to be observed which is shown on the display 1 and scrolls based on the detected scroll quantity. The scroll is fixed at the point of time when the sensor 4 is turned off, and an observer moves the display device 7 to a position where the observer easily sees it and observes display contents shown on the display 1. When scroll is performed again, the sensor 4 is turned on, the display device 7 is moved and the object to be observed is scrolled.

摘要： PROBLEM TO BE SOLVED: To precisely make color corrections by eliminating the color adaption of the eye by taking a measurement by taking measurements by a color measuring instrument while using a black patch as a background for a hard copy image and a color patch matching the patch color of the hard copy image at colorimetric level as the black patch of a background for a soft copy image. SOLUTION: The color patch of an image 12 of a hard copy image 14 on an observation table 16 and the color patch of a display soft copy image 20 on a CRT of the observation table 26 are measured by the color measuring instrument 28 respectively. Here, color corrections are made according to the measured values of the color measuring instrument 28 so that color tone of the color patches of the image 12 and display soft copy image 20 become equal. For the color corrections, the hard copy image has a patch of black or a chromatic color greatly different from an achromatic color in terms of saturation for the background. Further, the soft copy image has a patch of black or a chromatic color greatly different from an achromatic color in terms of saturation for the background as a color patch matching the patch color of the hard copy image at colorimetric level.

摘要： PROBLEM TO BE SOLVED: To generate a color conversion definition which has a high precision up to the area boundary of a color reproducing area on the basis of pairs of known points having large numbers of degree of freedom by a method which is highly useful for various devices. SOLUTION: The color conversion definition is generated through an approximation stage (S101) where a prescribed number of lattice points are set and positions of lattice corresponding points corresponding to them respectively are calculated by linear approximation on the basis of plural prepared pairs of known points, a first correction stage (S103) where positions of lattice corresponding points are so corrected that a coordinate conversion relation corresponding to a pair of known points selectively acquired from plural pairs of known points may be reproduced, and a second correction stage (S104) where positions of lattice corresponding points corresponding to lattice points in a correction area are corrected by an extent of correction according to the extent of position correction in the first correction stage.

摘要： PURPOSE:To prevent the images after processing from having unnatural tint at the time of converting read image data to color space data and processing the data within the color space. CONSTITUTION:An original 10 to be processed is read by an input means 20, such as color scanner or TV camera, and the optical data of every pixel constituting the image of the original 10 is determined. The optical data are sent to a processing system 30. The optical data are first converted to image data (XYZ) of a CIE XYZ color specification system and thereafter, the color desired to make the color after the processing colorless is set and the image data (XYZ) are successively converted to the equal color space (for example, CIEL*a*b* uniform color space) where this color is made reference white (W01). The color space data (L*a*b*) after the conversion are successively reverse converted to the image data of the color specification system before forward conversion with the chromaticity of the colorless color of the output medium as the reference white (W02). The data after the reverse conversion are outputted to a printer 40 and a CRT 70.
