Signal processing apparatus for determining color conversion processing for color-converting second color signal obtained by second image pickup device to color signal approximate to first color signal obtained by target first image pickup device and non-transitory computer-readable recording medium for recording signal processing program for the color conversion processing

摘要

A signal processing apparatus for determining color conversion for converting a second color signal obtained through image pickup by a second image pickup device to be processed to a color signal approximate to a first color signal obtained through image pickup by a target first image pickup device, including a spectral difference calculating section that calculates a difference between spectral characteristics of the first image pickup device and spectral characteristics of the second image pickup device for each of spectral characteristics corresponding to a plurality of color signals making up a color signal and a processing determining section that determines linear conversion as color conversion when the spectral difference value is equal to or less than a determination reference value and determines non-linear conversion as the color conversion when the spectral difference value is greater than the determination reference value.
