摘要
This color calibration device is a color calibration device, calibrating colors in a captured image of a first imaging device between different imaging devices using a hologram emitting diffracted light at different frequencies corresponding to an observation angle, the color calibration device includes: a diffracted light spectral distribution calculation unit that obtains respective diffracted light spectral distribution of the diffracted light from the hologram; a camera sensitivity function estimation unit that estimates spectral sensitivity of the imaging device from the respective diffracted light spectral distribution of the diffracted light and each captured image of the diffracted light; and a color calibration unit that calibrates difference in color of the first imaging device relative to a second imaging device different from the first imaging device using the estimated spectral sensitivity.
