Abstract
PURPOSE: To improve the measurement precision and eliminate human error by indicating deflection patterns on a film by dividing them in several stages as bright and dark information pieces at dots in a required interval and indicating the position of measurement by the operator who observes the indicated picture image.
CONSTITUTION: The picture image of a film which is an object of measurement is detectd by a picture input device 1 as an assembly of lights and shades of dots in required intervals (for example, 10 microns), and a necessary number of dots are supplied in a memory device 2. Then, lights and shades at all dots of the detected values and the cordinate values are stored in the memory device 2, and are introduced into a computing device 3, where a computation to divide the degrees of lights and shades into five stages is carried out, and the result is indicated in five stages by an indicator 4. By this procedure, the operator observes the indicated picture of the indicator 4, and instructs to supply the cordinate value at the position of a certain dot to be measured to the computing device 3, where the distance between bright dots on th film is computed and measured.
