  • Camera system, color conversion device and method employed thereupon, and recording medium for color conversion program
    Patent number: 9787965
    Abstract: A camera system includes: a database which stores a plurality of stereoscopic color profiles, in which conversion relationships calculated from second image data obtained by photographing a plurality of reference color stereoscopic objects assigned with reference colorimetric values in advance and the reference colorimetric values corresponding to the second image data are associated with a plurality of illumination conditions in photographing; a selection unit which, based on an illumination condition at the time of photographing of a stereoscopic subject, selects a stereoscopic color profile corresponding to the illumination condition; and a color conversion unit which performs color conversion from first image data of a photographed image of the stereoscopic subject to colorimetric values, based on the selected stereoscopic color profile.

  • Image information managing method, image information managing apparatus and image information managing system for preparing and measuring an evaluation chart
    Patent number: 8976428
    Abstract: An evaluation chart has test patterns, a first code mark, and a second code mark. The evaluation chart is electronically read at one time to obtain first code information that specifies measuring conditions for the evaluation chart and second code information that specifies image forming conditions for the evaluation chart. Quantized information of the test patterns that is measured under the measuring conditions is associated with the image forming conditions.
