PROBLEM TO BE SOLVED: To provide a method capable of distinguishing them simply by color standard when analysing natural environment and plant vegetation conditions by image processings. SOLUTION: An RGB value per picture element forming color image to be processed is obtained (image outputting part 1), a chromaticity plane coordinate position of picture element is obtained from color vector on an RGB three- dimensional coordinate of each picture element, and color of the picture element is distinguished using a distance from any vertex in the chromaticity plane as a reference (chromaticity coordinate calculation means 21), whether the picture element is within the reference or not is judged (judging means 23 and result outputting means 24), and the result of judgement is displayed (display part 3). |
