Abstract

PURPOSE: To decrease the number of processing steps, by picking up the profile information of characters and performing character recognition.
CONSTITUTION: The light from the document 1 is converted into binary video information with the sensor 2 and quantizing circuit 3, and stored in the memory 4. Every time when one line of the memory 4 is scanned, the changing point from white to black and present scanning line position is picked up and the profile address pick up circuit 5, and the position of changing point and present scanning line position is written in the profile address memory 6. The start point and end point 7-1W7-4 compare the changing point location at scanning line before one scanning and that at present scanning line, and if the both are discontinuous, the changing point location at scanning line before one scanning is taken as end point and that at present scanning line is taken as start point, and they are written in the memories 9-1W9-4. Character recognition is made based on the profile information of the memories 9-1W9-4 and white part characteristic pair memories 10-1W 10-2.
