Abstract

PURPOSE:To cut out and read characters from a complicated background, by cutting out them by detecting existence of parameters of characters. CONSTITUTION:The whole of the screen is divided into band-form regions in the Y direction vertical to the character string. The pattern is read in each region by the horizontal line, and the number of points of the character pattern and coordinates of edges of characters are obtained for every line by histogram operating circuit 10 and edge coordinate detecting circuit 11 and are input to data memory 12. A region where a character string exists is obtained on a basis of distribution (g) for every line, which is obtained by calculating the frequency of edge coordinates where the number of continuous points of 1 is equal of the character width, and distribution (f) for every line of the number of character pattern 1 by processor 4. Next, the horizontal band-form region between Ym and Ym+1 is scanned in the vertical direction to obtain the histogram of points of 1 and a histogram where the line width is equal to the line width of characters, and thus, characters are cut out one by one.
