PURPOSE:To execute the shape input in the 360 deg. direction since the three- dimensional coordinates of a substance are obtained together with the concentration and the color by investigating the texture on a scanning line pattern obtained by rotating an input object substance. CONSTITUTION:An input object substance 1 is crossed vertically to an optical axis 4 and rotated with a rotary shaft 6 at the relation orthogonal to the scanning line 5 of a television picture on an image plane as the center. Then, the projecting point 8 of a point 7 on the input object substance 1 is shifted on an image plane 3 archedly. When the point 7 is located higher (lower) than the light shaft 4, the arched upper-most (lower-most) part comes to be in parallel to the scanning line. The shifting extent on the image plane 3 of the projecting point 8 is different according to the distance from the rotary shaft 6 of the point 7 on the substance, and the extent at farther paint comes to be faster. By measuring the shifting extent, the distance between respective points and the rotary shaft on the substance is calculated and the three-dimensional shape of the input object substance is obtained.
