    Abstract: A method of deriving color response characteristics of an image acquisition device, the method including: collecting first training data sets; deriving a first-order color response characteristic of the image acquisition device by performing a matching operation of statistically matching a relationship between device coordinates and colorimetric coordinates of an image acquisition device using the first training data sets; collecting second training data sets corresponding to a spectrum of one or more edge regions of a color gamut of a color matching function representing a sensitivity of a human eye; and deriving a second-order color response characteristic of the image acquisition device by further performing the matching operation using the second training data sets.
