Abstract

PURPOSE:To convert information on a line picture into line-element information automatically, by outputting information put to an ending point right before an error between an imaginary segment and an original segment goes beyond prescribed range, by extending the imaginary segment successively when the error is within the prescribed range. CONSTITUTION:In a memory 3, a CPU2 determines one optional picture element in line picture information as a starting point A, whose circumference is scanned to set an imaginary segment AC connecting one picture element C and the starting point A. Then, a check on whether an error between the segment AC and an original segment shown by the line picture information is within prescribed range is made. As a result, when the error is within the prescribed range, the segment AC is extended successively and at the same time, the error in original segment is checked, thereby setting a point Q right before the error goes beyond the prescribed range as the ending point of the imaginary segment. Then, information showing the imaginary segment from the starting point A to the ending point Q is outputted, and the point Q is regarded as a new starting point. When the error goes beyond the prescribed range, the range of operation is narrowed down and the operation is performed.
