Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a method that enables correct automatic coloring of small areas in animated line drawings. So far, automation of the coloring work of animation line drawings has been proposed, and it is known that automatic coloring of large areas is relatively accurate, but small areas such as the eyes and nose of characters are colored with the correct color. It's difficult. Therefore, in this study, the purpose is to automatically color such a small area, and after enlarging only the small area included in the line art by geometric transformation, automatic coloring is performed. The proposed method can be colored with the correct color even for a small area, and the effectiveness of this method has been confirmed.
