PURPOSE:To segment accurately characters, by segmenting a read pattern for each row to store them and counting the number of vertical black picture elements and the number of groups of continuous black picture elements to obtain the difference of count values as well as the changing state of said difference. CONSTITUTION:A pattern read out of a slip, etc. is segmented 1 for each row and supplied to a character segmenting device 2 to be stored in a picture memory 11. Then the number of black picture elements is counted 12 for each vertical column, and at the same time the number of groups of continuous black picture elements (black run) is counted 13. A shadow block is detected 14 out of the output of the counter 12, and at the same time a sudden change position is detected 15 for the count value. Then a region changing position is detected 16 from the output of the counter 13. The segmenting position is decided 17 from those detecting positions. The memory 11 is segmented at a segmenting part 18 and fed to a picture memory 3. For instance, the black run is constant for the 11th and 12th columns shown in the figure, and the black picture element has a width approximately equal to the width of a line to be defined as a segmenting position candidate. Thus it is possible to segment characters even though no space exists between characters. |
