PROBLEM TO BE SOLVED: To provide an unevenness information generation device capable of generating information relating to uneven coating including both stain-like unevenness and stripe-like unevenness on a color filter manufactured by an ink jet method.SOLUTION: An unevenness information generation device generates a post-Fourier transformation image by performing Fourier transformation processing to a photographed image obtained by photographing a color filter coated with ink, generates a stain-like unevenness image by performing Fourier inverse transformation processing to an image obtained by extracting a stain-like unevenness frequency component from the post-Fourier transformation image, and generates a stripe-like unevenness image by performing Fourier inverse transformation processing to an image obtained by extracting only a stripe-like unevenness frequency component from the post-Fourier transformation image. |
