Grayscale image generation device, grayscale image correction method, and grayscale image correction program

A grayscale image correction method, comprising:

• a distance information acquisition step of acquiring information about a distance to an object according to an amount of reflection of electromagnetic waves with which the object is irradiated from a lighting device;
• a grayscale information acquisition step of acquiring grayscale information according to the amount of reflection of the electromagnetic waves emitted from a lighting device and irradiating the object;
• a correction step of correcting the grayscale information acquired in the grayscale information acquisition step based on the distance obtained in the distance information acquisition step;
• and
• an image generation step of generating a grayscale image on the basis of the grayscale information corrected in the correction step.
