20090087091 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - When converting image data constituted by a plurality of objects to data for an output device, color appearances of object images specified as a same output color are set so as to not vary even when their respective background colors vary. A color appearance model forward conversion section uses forward conversion of a color appearance model to calculate target appearance colors, which are targets of appearances of objects based on color information of the objects. A surrounding adaptive background color obtaining section generates surrounding adaptive background colors based on pixels around a pixel of interest for object images that have undergone rendering. Then, output pixel values of the pixel of interest are calculated by a color appearance model reverse conversion section using reverse conversion of the color appearance model based on the target appearance color and the surrounding adaptive background colors. | 04-02-2009 |
20100053652 | CHART FOR COLOR CALIBRATION, CALIBRATION METHOD AND IMAGE COLOR CALIBRATION SYSTEM USING THE CHART - In a chart for color calibration which is output and calorimetrically measured for color calibration of a printer device, respective charts of a color chart are arranged obliquely with respect to the alignment direction of grid points in a printer device color space or in a state that a plane in which charts are arranged on grid points and a plane in which charts are not arranged on grid points are alternately combined, on a color space of the color chart. With this configuration, a novel chart for color calibration which assures higher accuracy despite having a smaller number of steps (number of charts), and an image processing method and image processing apparatus using the chart are provided. | 03-04-2010 |
20100053653 | METHOD FOR GENERATING A COLOR CHART - A method is provided for generating a color chart for a printer, which color chart comprises a plurality of elements. The method comprises obtaining reference color data representing colors output by the printer, when the printer is in a reference state. Further, comparison color data representing colors output by the printer, when the printer is in another state is obtained. Differences in color between corresponding elements of the reference color data and the comparison color data are determined and at least one region of the output color space of the printer is classified as a linear region in which the differences vary substantially linearly. The method includes selecting colors of the elements of the color chart on the basis of the linear region. | 03-04-2010 |
20100086201 | IMAGE PROCESSING APPARATUS AND COLOR PROCESSING METHOD - The colorimetric values of a plurality of reference color patches formed on a specific medium are measured at a plurality of temperatures, and a temperature characteristic LUT in a colorimetric value temperature correction unit is created based on the colorimetric values. Upon creating a calibration LUT, a patch based on arbitrary device values is formed on the medium, and a patch temperature and colorimetric values are acquired immediately after fixing of that patch. A correction target temperature as a temperature upon observation of the medium is, for example, fixed, the colorimetric values are corrected by interpolation processing based on the temperature characteristic LUT to obtain colorimetric values, and a calibration LUT is created based on the colorimetric values. | 04-08-2010 |
20110149319 | IMAGE PROCESSING APPARATUS AND COLOR PROCESSING METHOD - It is difficult to appropriate estimate the colorimetric values of an arbitrary patch at a desired temperature with respect to an arbitrary medium in consideration of the influence of a fluorescent whitening agent contained in the medium. Target patch colorimetric values obtained when patches of a plurality of colors formed on a medium using color samples are measured at a target temperature designated in step S | 06-23-2011 |
20110164287 | IMAGE PROCESSING APPARATUS AND COLOR PROCESSING METHOD - It is difficult to appropriately estimate the colorimetric values of an arbitrary patch at a desired temperature with respect to a medium containing a fluorescent whitening agent in consideration of the influence of the fluorescent whitening agent. A target temperature and media type are designated (S | 07-07-2011 |
20110255105 | IMAGE PROCESSING APPARATUS AND COLOR PROCESSING METHOD - The invention provides an image processing apparatus comprising: forming means for forming a patch based on patch data on a medium; temperature measuring means for measuring the temperature of a white paper portion of a medium to obtain a white paper temperature; colorimetry means for obtaining a colorimetric value by measuring the color of the patch formed on the medium; estimation means for estimating a colorimetry temperature, which is the temperature of the patch at the time when the colorimetry means measures its color, based on the patch data and the white paper temperature; and correction means for correcting the colorimetric value based on the estimated colorimetry temperature. | 10-20-2011 |
20130293694 | MEDICAL SUPPORT SYSTEM - There is provided a medical support system in which a plurality of photography apparatuses and a portable-type viewer apparatus including a display unit are communicably connected to a server. The portable-type viewer apparatus includes: a selection unit that selects one of the plurality of photography apparatuses; and a photographer ID input unit that inputs a photographer ID that is an ID of a photographer photographing a subject using the selected photography apparatus. The selected photography apparatus further includes a transmission unit that transmits image data of the subject photographed by the selected photography apparatus to the server, and the server includes a recording unit that records the photographer ID and the transmitted image data in association with each other in a case where the photographer ID is input. | 11-07-2013 |
