Image processing device, image processing method, and non-transitory computer-readable recording medium storing image processing program

An image processing method, comprising:

• inputting a facial image from a predetermined device;
• calculating one of facial shape, proportion lines that are lines drawn on the face to analyze the balance of the face, and blocking lines that divide the face into multiple regions following the structure of the face according to lightness and darkness of shadows due to light striking the face, based on facial feature points extracted from the facial image;
• deciding a superimposing region of a makeup parts image in the facial image, based on one of the facial shape, the proportion lines, and the blocking lines;
• and
• generating a simulation image where the makeup parts image has been superimposed on the superimposing region.
