Abstract

본 발명은 화신호의 상역분리회로 및 그 방법에 관한 것으로, 종래에는 화상처리시 그림과 문자의 구별없이 디더화하여, 중간조 처리결과 그림은 양호하나 문자가 흐려져 인식이 어려운 문제점이 있었다.The present invention relates to a phase separation circuit of a speech signal and a method thereof. Conventionally, when image processing is performed, the image is dithered without distinguishing between a picture and a character.

본 발명은 이와 같은 종래의 문제점을 감안하여, 그림의 문자의 특징 축출방식으로 그림과 문자의 데이타를 분리하고 합성하여, 원하는 형태로 선명한 원고를 재현할 수 있도록 한 것이다.SUMMARY OF THE INVENTION In view of such a conventional problem, the present invention separates and synthesizes data of a picture and a text by the feature extraction method of the text of a picture, so that a clear original can be reproduced in a desired form.
