Abstract: If gamut mapping (hue restoration) defined by one Lab color space is applied in color matching under different reference white points, the human vision perceives the hue as inconsistent. In view of this, input data which is dependent on a color space of an input device is converted by the conversion LUT 11 to color space data which is independent of any devices, based on a viewing condition at the time of viewing an input original. The data is converted to data in the human color perception space by the forward converter 12, then subjected to gamut mapping, and converted back to data in the color space independent of any devices by the inverse converter 15, based on a viewing condition at the time of viewing an output original. Then, the data is converted to output data in a color space which is dependent on an output device by the conversion LUT 16.

Abstract: Upon reading an A3-size sample image, a colorimeter that can read A3 size can be used but such A3-size calorimeter is expensive. For this reason, an A3-size recording paper sheet is cut into halves, i.e., two A4-size sample images, which are measured by an A4-size calorimeter. To prevent such troublesome operation, color patches are divided into nearly half groups, and these color patch groups are printed on an A3-size recording paper sheet to have their top positions on the opposite sides. In this way, after one color patch group is measured, the sample image is rotated through 180° and is set on the calorimeter to measure the other color patch group.

Abstract: When color matching using CIECAM97s is carried out, it is required that the characteristics of lighting conditions be detected simply and accurately. In a conventional method of detecting lighting conditions, accurate characteristic values cannot be detected if the user selects lighting conditions of a variety of types sensorially. If detection is performed directly by a photometric sensor, on the other hand, apparatus having a complicated structure is required. According to the invention, therefore, the rated-product number of a lighting lamp is input, a lighting characteristic value is calculated based upon the rated-product number, and color matching processing is executed using a color appearance model that is based upon the lighting characteristic value. As a result, lighting characteristics can be detected simply and accurately and it is possible to execute color matching processing using a color appearance model that takes lighting into account.

Abstract: The prevalence of the Internet and the like allows the user to form an image using a printer located at another site. In this case, it is required to simulate (or preview) a color matching output of the printer at a remote site (another site). To this end, a client prompts the user to select a printer used as a print simulation target at the remote site, a printer of the self site, which is used to output the simulation result of the target printer, and a profile required for the color matching process of the print simulation. The selected profile is acquired by searching a profile database present at the remote site or the self site, and a use designation of that profile is sent to the target printer. Image data which is to undergo a color matching process is then transmitted to the target printer, and image data that has undergone the color matching process is received from the target printer. The received image data is transferred to the simulation output printer.

Abstract: Disclosed are a highly versatile image processing method and apparatus wherein it is possible to preview an image that takes into account a change in the color reproduction characteristic of an output device with the passage of time, as well as a computer readable memory storing a program for executing this preview processing. A printer that outputs an image is calibrated in regard to its image output characteristic and a set of one-dimensional LUTs that conforms to the color reproduction characteristic of the printer is generated. On the basis of the set of one-dimensional LUTs, the content of a set of one-dimensional LUTs, which is used when PCS data that has been stored in a profile corresponding to the printer is converted to data dependent upon the printer, is modified, and another set of one-dimensional LUTs, which is used when data dependent upon the printer is converted to PCS data, is modified.
