Visualization of the vector fields is usually carried out by means of the vector arrow map. However, this conventional visualizing methodology to the vector fields is not applicable to image cognition method, because most of the image cognition method is applicable to the scalar images. To overcome this difficulty, we have previously proposed that the vector fields are visualized as the color images by projecting the x, y, and z components in each of the vectors to the red, green, and blue components of light, respectively. By means of this visualizing methodology, we have succeeded in carrying out the nondestructive inspection of various electrical as well as electronic devices in a quite efficient manner.However, this visualizing methodology of vector fields has the problem that the visualized images always depend on the reference coordinate system.In this paper, we propose a technique of how to decide reference coordinate system for visualizing the vector fields as the scalar color images. Further, visualized images of the practical magnetic field distributions by our method are demonstrated.
