Abstract

Remodeling electronic endoscopy and utilizing its delay circuit, image enhancement against signal of each R, G and B was carried out. This method is a kind of procedures by electronic signal, and can be proceded wide patterns, and has excellently laborious and economic advantages being performed at the real time. The effect of this method was evaluated in 32 cases with gastroduodenal ulcer, 40 cases with gastritis, 12 cases with gastric polyp, 8 cases with gastric cancer and other 47 cases. Excellent demonstration of uneven lesions was obtained by the image enhancement using the component of R, and patterns were effectively obtained due to the enhancement of shadow parts together with somewhat enhancenent of color tone keeping comparatively character of lesion. The excellent demonstration of micro-blood vessels and enhancement of margins of lesions and intragastric structures were obtained by the image enhancement using the component of G. This is concerned in a fact that G (green) itself has discrimina-tion area and visual sensitivity for eyes of human, in addition, structure informations such as lesions, ete., are largely controlled by the G component, and this was understood by the supplementary study due to convertible patterns of white black corresponding to the sigunal volume. Rough patterns are occasionaly obtained due to the change of color of pattern elements requiring for the image enhancement of each R, G and B, and increase of noise, while simple and practical image enhancement of each R, G and B is clinically useful for the acquisition of many patterns with further informations.
