As digital cameras have been used widely, a technology to extract features of character string areas from scenery (nature) image is required. However, it is very difficult to extract character string areas from a complex background of scenery image as compared with a relatively simple background of documentary image. Human can extract of character string areas from scenery image having complex background. Therefore, a fairly high degree of accuracy in the extraction of character string areas may be attained by imitating the human visual processing system. In this paper we proposed the method to extract character string areas from color scenery images using the psychological potential field^<1), 2)> (imitating the human visual processing system). We have also executed the experiment and obtained the favorable processing results that are close to the human sense and unlikely to be affected by amounts of color information and photographing conditions. And, this method have high degree of accuracy in the extraction of character string areas when it is applied to the color scenery image.
