Abstract
An information processing method, comprising acquiring a photographed image of a color sample including specific color markers, binarizing a signal indicating luminosity of the photographed image, detecting a marker area, plotting a color signal of the marker area on a color plane, labeling for a plotting result, and setting a color recognition parameter for identifying the color area of the specific color markers from the labeling result.
