PURPOSE:To improve a processing result and to high-speed a processing by making a picture element adjacent to the picture element of a characteristic picture element value remain when it is confirmed that the width of two picture elements is confirmed and changing the picture element of the characteristic picture element value to a peripheral picture element value at the time of a scanning after the scanning of the time. CONSTITUTION:The processing of an endpoint is of a parallel type, the remaining of 'a palp' backwards in a scanning direction is prevented, and further, attention is paid to the processing of the straight line of the width of the two picture elements along the advancing direction of a scanning line and the parallel direction of the scanning line. That is, when the possibility to produce the straight line of the width of the two picture elements occurs, the picture element value of an object picture element is made into the characteristic picture element value, when it is confirmed that the width of the two picture elements is obtained, the picture element adjacent to the picture element of the characteristic picture element value is allowed to remain, and the picture element of the characteristic picture element value is changed to the peripheral picture element value at the time of the next scanning. Thus, the processing result is improved and a high-speed processing is realized. |
