| 20090027746 | CONVERSION TABLE CREATING DEVICE, STORAGE MEDIUM STORING CONVERSION TABLE CREATING PROGRAM, AND CONVERSION TABLE CREATING METHOD - Each of a plurality of polyhedron spaces is defined by a plurality of first vertices. Bach of the plurality of first vertices is defined by a plurality of sets of third color data that are defined in the second color space. A color data setting unit sets a plurality of sets of fourth color data that are defined in a first color space in one to one correspondence with the plurality of third color data sets. A second dividing unit divides each of a plurality of polyhedron spaces into a plurality of smaller polyhedron spaces by a division number set for the each polyhedron spaces. Each of the plurality of smaller polyhedron spaces is defined by a plurality of second vertices and the plurality of first vertices. Each of the plurality of second vertices is defined by a plurality of sets of fifth color data defined in the second color space. An interpolation calculation unit calculates a plurality of sets of sixth color data that are defined in the first color space in one to one correspondence with the plurality of second vertices by interpolating the plurality of the fourth color data sets. A conversion table creating unit creates a conversion table based on the fourth color data sets and the sixth color data sets and on the third color data sets and the fifth color data sets. | 01-29-2009 |
| 20090185245 | CONVERSION TABLE CREATING DEVICE, STORAGE MEDIUM STORING CONVERSION TABLE CREATING PROGRAM, AND CONVERSION TABLE CONVERTING METHOD - An update performing unit repeatedly performs an updating process by controlling a second reference point setting unit to set a plurality of second reference points that are uniformly distributed in a subspace in the second color space; a calculation unit to calculate color differences between a set of fifth color data for each second reference point in the subspace and a single first reference point; a first judging unit to judge whether or not the smallest color difference among all the color differences with respect to each of the second reference points in the subspace is smaller than a color difference registered at the single first reference point; and a updating unit to update, if the first judging unit judges that the smallest color difference is smaller than the color difference, a set of fourth color data, that is already registered at the single first reference point, to a set of fourth color data for the each second reference point in the subspace. | 07-23-2009 |
| 20090231646 | COLOR PROCESSOR, COMPUTER READABLE MEDIUM AND COLOR PROCESSING METHOD - The color processor is provided with: a conversion source color data acquiring part for acquiring conversion source color datasets in a first color space; a gamut storage for storing a gamut; a determining part for determining whether or not each of the conversion source color datasets exists in the gamut; a first color conversion processor for performing color conversion processing on each of conversion source color datasets A in the conversion source color datasets by use of a color conversion characteristic model, the conversion source color datasets A being determined to exist in the gamut; and a second color conversion processor for performing color conversion processing on each of conversion source color datasets B in the conversion source color datasets by use of color conversion correspondence, the conversion source color datasets B being determined not to exist in the gamut. | 09-17-2009 |
| 20100208312 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD THAT CORRECT COLOR CONVERSION TABLE USED WHEN READING DOCUMENT - Conventionally, it is not possible to evenly correct a color conversion table of a reading device in the entire color region even with a limited number of patches. In order to correct a color conversion table, a color conversion table from a device-independent color space into a device-independent color space is newly stored. A shift in read data between devices is reflected in a correction 3D-LUT and a color conversion table is corrected using the correction 3D-LUT. Thereby, it is possible to correct the entire color region with a smaller number of pieces of data and with less time and effort than when a color conversion table is newly recreated. | 08-19-2010 |
| 20120013959 | IMAGE PROCESSING APPARATUS - An image processing apparatus is provided. The image processing apparatus includes: an acquiring unit that acquires original image data and a first color conversion profile associated with the original image data; an editing unit that edits the original image data by using the first color conversion profile to generate edited image data; a preparing unit that prepares a second color conversion profile different from the first color conversion profile in a first case where the editing unit generates the edited image data having a data size smaller than that of the original image data, wherein a data size of the second color conversion profile is smaller than that of the first color conversion profile; and a storage control unit that, in the first case, stores the edited image data and the second color conversion profile in a memory while being associated with each other. | 01-19-2012 |
| 20150070738 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING SYSTEM, AND IMAGE PROCESSING METHOD - The present invention includes a first generating unit that generates a recording-amount of a chromatic-color-material in each pixel of a color-image from first image data indicating the color-image; a second generating unit that generates a recording-amount of a transparent-color-material in each pixel of a transparent-image from second image data indicating the transparent-image; a storage unit that stores an upper-limit-recording-amount of the color-materials and an upper-limit-recording-amount assignable to the transparent-color-material, for color material image data indicating an image formed from the recording-amount of the chromatic-color-material and the recording-amount of the transparent-color-material; and a correcting unit that calculates a recording-amount assignable to the transparent-color-material by subtracting the recording-amount of the chromatic-color-material from the upper-limit-recording-amount of the color-materials, and corrects the recording-amount of the transparent-color-material in each pixel based on a ratio of the calculated recording-amount assignable to the transparent-color-material and the upper-limit-recording-amount assignable to the transparent-color-material. | 03-12-2015 |
| 20160191745 | PRINT DATA GENERATING APPARATUS AND GENERATING METHOD FOR GENERATING COLOR CONVERSION PROFILE - A print data generating apparatus executes color conversion on image data using a color conversion profile to generate print data. In the color conversion profile, each of a plurality of sets of specific color data defined in a specific color space are associated with a set of first ink color data defined in an ink color space. A part of the plurality of sets of specific color data are further associated with a set of second ink color data defined in the ink color space. In bi-directional printing, a print executing unit uses the first ink color data to execute one of forward print and backward print, and uses both the first ink color data and the second ink color data to execute another of forward print and backward print. | 06-30-2016 |
