PROBLEM TO BE SOLVED: To solve the problem that the conventional image processing takes much processing time to reduce color blur. SOLUTION: A computer 21 as the nucleus of image processing determines whether or not a pixel of interest is a color blue pixel, based on the intensity of a low-density element color, at steps S130 and S140. If the pixel is a color blue pixel, the computer 21 determines whether or not the color blue pixel is an edge pixel at step S150. If the pixel is not an edge pixel, the computer 21 uses a smoothing filter at step S152, while if the pixel is an edge pixel, the computer 21 uses a median filter at step S154, in image processing to reduce the color blur. This reduces the amount of calculation and realizes high-speed image processing. |
