Abstract
Abstract Horizontal lines of a character are divided into groups of lines which are not offset from each other and distances between which are less than a predetermined value. Further, on conditions that two groups contain at least one common line and overlapping portion of lines of one group is offset from none of lines included in the other group, these two groups are combined. Consequently, space correction groups for the horizontal lines are formed. Then, by using areas of the horizontal lines included in the groups obtained as described above as space correction areas, spaces defined by points on outline of each line are corrected. As a result, it is possible to form a character of high quality by using data which does not include information on space correction.
