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.
