A color calibration device for calibrating the various colors of a captured image of one of different image capture devices using a hologram that emits diffraction light of different frequencies corresponding to observation angle, the color calibration device being provided with: a diffraction light spectral distribution computing unit which determines the respective diffraction light spectral distribution of diffraction light from the hologram; a spectral sensitivity estimation unit which estimates the spectral sensitivity of the image capture device from the respective diffraction light spectral distribution of diffraction light and the respective captured image of diffraction light; and a color calibration unit which, using the estimated spectral sensitivity, calibrates a color difference of the image capture device with respect to another image capture device different from the image capture device.
