Abstract:
A color correction apparatus for use with a first imaging apparatus which outputs a first video signal and a second imaging apparatus which outputs a second video signal, said color correction apparatus comprising:specifying means for specifying reference colors in said second video signal which are to be weighted and for setting a weighting level for each of the specified reference colors, each said weighting level being settable such that no color correction is performed for the corresponding reference color;color setup means for generating a set of weighted adjustment coefficients related to color differences between said first video signal and said second video signal using said weighting levels corresponding to said specified reference colors in which a minimum color difference occurs; andcolor correction means for correcting a plurality of colors of said first video signal by performing a calculation using the set of weighted adjustment coefficients, so that the corrected colors of said first video signal substantially match a corresponding plurality of colors in said second video signal output from the second imaging apparatus with the closest match occurring for said reference color.
