PROBLEM TO BE SOLVED: To efficiently classify data. SOLUTION: A tap constitution part 2 constitutes an axis calculation tap as plural pixels to be used for transforming R, G and B axes for expressing a pixel value to X, Y and Z axes in the respective directions of the first, second and third main components, and an axis calculation part 3 obtains the X, Y and Z axes based on the axis calculation tap. Furthermore, the part 2 constitutes a class tap as the plural pixels to be used for classifying picture elements under consideration, and an axis transforming part 4 transforms the plural pixels as the class tap to a pixel value expressed on the X, Y and Z axes. Then a classifying part 5 classifies the data based on the class tap expressed by the X, Y and Z axes. |
