Abstract
An image processing method according to the invention is for dilating an object in a binary image represented by run-length code. The image processing method includes obtaining a target dilation amount representing how much the object is to be dilated, determining a first dilation amount decreasing as a density of runs in the image increases, comparing the target dilation amount and the first dilation amount, and performing an dilation processing based on the comparison result. If the target dilation amount is larger than the first dilation amount, a first dilation processing by the first dilation amount and a second dilation processing after the first dilation processing by a second dilation amount are performed. The second dilation amount is a difference between the target dilation amount and the first dilation amount. Otherwise, the dilation processing by the target dilation amount is directly performed.
