Claim One:
1. An image filling method comprising the steps of: separating a reference line drawing into first closed regions, said reference line drawing being read from a storage device and being an original line drawing of a reference picture; extracting at least one feature amount of said first closed regions other than the barycenter; separating a line drawing to be filled into second closed regions, said line drawing to be filled being read from a storage device; extracting at least one feature amount of said second closed regions other than the barycenter; calculating variations of feature amounts between every combination of said first closed regions and said second closed regions, sorting said first closed regions in ascending order by the variation of the feature amount for each of said second closed regions; generating color candidate lists for each of said second closed regions, wherein color information corresponding to said first closed regions is obtained from said reference picture and duplication of said color information is eliminated; and filling each of said second closed regions with a color which is on the top of said color candidate list corresponding to said second closed region.
