In a system for converting an input image signal input from an image input device into an output image signal to be output by an image output device, an image compression unit converts a spectral image input via an image input unit into R, G, and B data, obtains principal component data by making principal component analysis of the spectral image, and stores these data in an input image storage unit. When the principal component data and R, G, and B data are loaded and stored in an output image storage unit, a spectral reflectance reconstruction unit reconstructs the spectral reflectance of each pixel using these data. A printer model determines the dot quantities of inks used to record each pixel in an image output device on the basis of the calculated spectral reflectance, and generates an output image signal for the image output device. In this way, image data which allows to estimate the spectral reflectance characteristics of an input image is provided, and faithful color reproduction can be realized.

Image processing system, apparatus, and method, and color reproduction method

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.

Generating a look-up table for use in color processing

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.

Color processing apparatus and its method

A body structure for an automotive vehicle includes a side member, an outer back panel and an inner back panel. The side member extends generally vertically and defines a rear pillar of the vehicle. The side member has an inner flange. The outer back panel has a middle wall extending generally transversely in the vehicle. The outer back panel has a connecting wall extending from the middle wall. The inner back panel has a center wall extending generally transversely in the vehicle. The inner back panel has a connecting flange extending from the center wall. The inner back panel is spaced apart from the outer back panel to define a cavity in which a rear window is disposed. The connecting flange, connecting wall and inner flange are fixedly secured to each other to define a longitudinally extending seal that prevents liquid from passing between the cavity and an inside region of the vehicle.

Vehicle rear window body structure

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, when CIEL*a*b* values are converted into CIEXYZ values, and the XYZ values are converted into color appearance space values using color appearance conversion formulas, a point which can be converted and becomes a nearest neighboring point for a point that satisfies a predetermined condition is retrieved, and corresponding color appearance space values are calculated. The obtained color appearance space values are mapped on a predetermined device gamut.

Color processing apparatus and method

A spectral distribution error evaluation apparatus is used to evaluate precision of color matching between evaluation and target colors. A first weighting function generator generates a first weighting function on the basis of color matching functions, wavelength characteristics which are independent of a light source of the target color, and visual characteristics which depend on wavelengths. A second weighting function generator generates a second weighting function on the basis of light source information of selected light sources. A difference calculator calculates error values between the evaluation and target colors for respective frequencies. An evaluation value calculator applies the first and second weighting functions to the error values, and calculates the sum total of the error values as an evaluation value. In this way, a precision evaluation value which has high correlation with actual color appearance and is used to improve the color matching precision can be calculated independently of a change in condition such as a light source or the like.

Color evaluation apparatus and method

When an output image is observed, an image processing apparatus by which image observation can be performed always in a satisfactory state irrespective of its observation environment and a change of a human's visual characteristic is provided. In this image processing apparatus, a first output unit outputs the target image in a first gradation reproduction range, and a second output unit outputs the target image output by the first output unit in a second gradation reproduction range. At this time, a correction unit performs a correction process, i.e., gradation conversion process, to the target image output by the second output unit, on the basis of information concerning the environment for observing the output result of the target image by the second output unit.

An image processing method creates a lookup table having a plurality of grids. The image processing method includes the steps of selecting a grid having a small difference from a target grid from among grids whose output values are calculated; setting an output value of the selected grid as an initial value; optimizing an output value of the target grid by using the set initial value; and storing the optimized output value as an output value of the target grid.

Image processing apparatus and image processing method

An image processing apparatus and information processing apparatus and method employs an output profile read-out unit that, according to a region designated by a preference selection unit, reads out one or more regional profiles from output profiles prepared for each such region. An output profile composing unit then combines the one or more output profiles based on a composition ratio input from the preference selection unit. The output profile is then input to a color matching processor for color matching.

A primary color dot gain correction unit corrects the spectral reflectance of each of a plurality of color agents on the basis of the dot quantity set for each color agent. An initial estimated value calculator estimates a mixed color by the KM theory using spectral reflectance data corrected by the primary color dot gain correction unit. An ink overlap correction coefficient storage unit stores correction coefficients, which are determined on the basis of errors between the actually measured values of spectral reflectance data of color patches obtained using the plurality of color agents, and estimated values estimated by the initial estimated value calculator based on the dot quantities of the respective color agents on the color patches. An ink overlap correction unit obtains the prediction result of a reproduction color by correcting the spectral reflectance data of the mixed color calculated by the initial estimated value calculator on the basis of the correction coefficients stored in the ink overlap correction coefficient storage unit.
