Abstract

PURPOSE: To realize an easy and to accurately collate an original pattern with a test pattern, by viewing, by using a color cathode-ray tube and making use of a change of color due to the principle of the additive color mixture.
CONSTITUTION: One of the three primary colors is selected for the background color of the screen 1' of a color cathode-ray tube 1. Both the original pattern and a test pattern 8 are projected on the screen 1' in the colors different from the background color and in the form of an original pattern picture A and a test pattern picture A' respectively. Then both pictures are superposed on each other, and a coincident part B between the pictures A and A' is turned white by the additive color mixture of the three primary colors. While the noncoincident parts C and C' keep their colors as they are. Thus the screen 1' which is divided into three colors is viewed to discriminated the coincidence or noncoincidence between the pictures A and A'. In such way, an original pattern and a test pattern are collated with each other by viewing and an easy and accurate way.
