Abstract:
An image processing apparatus scans image data along a row in an x direction, and if a series of black pixels having a length equal to or more than a first threshold is detected, the series of black pixels is determined as a rule and erased. Furthermore, if a series of black pixels having a length equal to or more than a second threshold that is connected to the rule and extends in a y direction is detected, the series of black pixels is determined as a rule and erased.
