PURPOSE:To attain separation/extraction of characters which are written with no writing conditions by tracking the outer circumference of a character within a picture of an input character string with fixed conditions and segmenting an area of a character including the character to eliminate noises other than the character. CONSTITUTION:A character string area within a picture is fetched to a buffer memory 2 of a rectangular area after a digital picture such as a logical circuit diagram, etc. is stored to a picture memory 1. Then the character string area is scanned vertically to detect a tracking start point for outer circumference of character. Thus the outer circumference of the character is tracked by a round based on said start point and in a fixed checking order. A character frame area is segmented according to the minimum and maximum points which are extracted from said tracking process and stored to a one-character buffer memory 5 and then to a one-character store part 7 after elimination of noises through a noise eliminating part 6. The stored frame area is used for recognition of characters and also supplied to a one-character erasing part 8, and an EOR operation is performed between the separated character and a corresponding character of the memory 2. Then a character string including no processed character is stored to the memory 2.
