<P>PROBLEM TO BE SOLVED: To provide a color adjustment device which enables color adjustment with high precision regardless of characteristics of an infrared cut filter while preventing an increase in size of a facility and an increase in adjustment time. <P>SOLUTION: A color adjustment device performs the following steps of: obtaining relative spectral sensitivity data of an imaging system member at a specific wavelength from color signal data which has been obtained by photographing with a digital camera 26 while rotating a BPF disk 24; calculating relative spectral sensitivity data at an interpolation wavelength other than the specific wavelength using the color signal data which has been obtained by photographing and reference data; calculating relative spectral sensitivity data at a wavelength of 630 [nm] according to a predetermined interpolation formula using the relative spectral sensitivity data at wavelengths of 620 [nm] and 640 [nm] which has been obtained from the color signal data; obtaining the relative spectral sensitivity data at the specific wavelength and the interpolation wavelength; and then obtaining the relative spectral sensitivity data for each color component of the imaging system member by spline interpolation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
