20090128663 | IMAGE SENSING APPARATUS AND METHOD FOR CONTROLLING THE SAME - When a chart is used as a subject, whether or not the chart can be captured for storage is determined based on the result obtained through distance measurement at a plurality of locations in a field captured for temporary display on a viewfinder. For example, a maximum difference of distances ΔL is calculated. It is determined that the chart cannot be captured for storage if ΔL is greater than a depth of field or is greater than a predetermined TL. A message indicating that the chart cannot be captured for storage is provided. Furthermore, it is determined that the subject is not the chart to be captured for storage if a subject size does not fall within a predetermined range. | 05-21-2009 |
20090168084 | COLOR PROCESSING APPARATUS AND CONTROL METHOD THEREOF - The number of color patches is reduced to attain high-precision color estimation. Hence, the colorimetric values of a plurality of color patches of at least one primary color output by an output device are input. Based on the colorimetric value of first color patches corresponding to a part of the plurality of color patches, colorimetric values corresponding to second color patches other than the first color patches of the plurality of color patches are estimated. Errors between the input colorimetric values of the second color patches and the estimated colorimetric values corresponding to the second color patches are calculated. A plurality of color patches corresponding to the output device is determined based on the calculated errors. | 07-02-2009 |
20090244573 | COLOR PROCESSING APPARATUS AND METHOD THEREOF - Colorimetric values for generating a color separation table, which are obtained by measuring a plurality of color patches included in a color chart, are input, and measurement values corresponding to the input plural measurement values other than supervised input measurement values are estimated using supervised measurement values. Then, color differences between the estimated measurement values and the input plural measurement values other than the supervised measurement values are calculated. Based on the color differences, it is determined whether printing of the plurality of color patches or measurement of the plurality of color patches has been performed correctly. | 10-01-2009 |
20100321522 | IMAGING APPARATUS, SIGNAL PROCESSING METHOD, AND PROGRAM - Output signals (pixel values) output from a sensor unit in which image sensors having six kinds of color filters with different colors are arranged are classified in association with three stimulus values, a color number is reduced by performing addition processing of the output signals (pixel values) in each classification to generate an image signal of three bands, and the generated image signal is used for the preview display so that a photographed image can be checked easily and immediately. | 12-23-2010 |
20110134449 | COLOR PROCESSING APPARATUS AND METHOD THEREOF - A color value of output color reproduced based on an output signal value corresponding to an input color value of a grid point in an input color space, which is obtained by sampling a range of the output signal value, are estimated. An evaluation value that evaluates tonality between a color value estimated in correspondence with an input color value of a grid point of interest in the input color space and color values estimated in correspondence with input color values of grid points adjacent to the grid point of interest is calculated. When the input color value of the grid point of interest, whose evaluation value is less than a predetermined threshold value, is obtained, an output signal value corresponding to that input signal value is set in the grid point of interest. | 06-09-2011 |
20110134487 | COLOR PROCESSING APPARATUS AND METHOD THEREOF - Color values of output colors reproduced based on output values corresponding to input values of grid points in an input color space, which are obtained by sampling a range of the output values, are estimated. Changes between a color value estimated in correspondence with an input value of a grid point of interest and color values estimated in correspondence with input values of adjacent grid points, changes between an output value of the interest point and output values of the adjacent points, and changes between a plurality of color values estimated in correspondence with input values to the interest point in association with different light sources are evaluated. When the input value of the interest point, whose a sum of evaluation values of these evaluations is less than a threshold, is obtained, an output value corresponding to that input value is set in the interest point. | 06-09-2011 |
20120113446 | COLOR PROCESSING APPARATUS AND CONTROL METHOD THEREOF - The number of color patches is reduced to attain high-precision color estimation. Hence, the colorimetric values of a plurality of color patches of at least one primary color output by an output device are input. Based on the colorimetric value of first color patches corresponding to a part of the plurality of color patches, colorimetric values corresponding to second color patches other than the first color patches of the plurality of color patches are estimated. Errors between the input colorimetric values of the second color patches and the estimated colorimetric values corresponding to the second color patches are calculated. A plurality of color patches corresponding to the output device is determined based on the calculated errors. | 05-10-2012 |
20140340707 | MEASUREMENT APPARATUS AND CONTROL METHOD THEREOF - A measurement apparatus comprises a light source of line shape configured to move in a predetermined direction and illuminate a measurement target object, and a capturing unit configured to capture the measurement target object illuminated by the light source of line shape. The measurement apparatus controls the light source of line shape and the capturing unit, and estimates the reflection characteristics of the measurement target object from a plurality of images captured by the capturing unit. | 11-20-2014 |
