Patent ID: 8422774

Claim:
An image processing apparatus, comprising: an image input unit for inputting an image including one or more color regions; a color region dividing unit for dividing the inputted image into regions according to respective colors; a monospaced line/surface separating unit for separating each of the divided color regions into a monospaced line region and a surface region; a monospaced line region filling unit for obtaining a union of the surface regions of the respective color regions separated by the monospaced line/surface separating unit, and filling an region where the separated monospaced line region is present in an image of the obtained union with a color of a surface region adjacent to the region; and a vectorization unit for generating vector data of a monospaced line based on the monospaced line region separated by the monospaced line/surface separating unit, and further generating vector data of the surface region based on a contour of a surface region extracted from an image having been filled by the monospaced line region filling unit.
