Abstract

PROBLEM TO BE SOLVED: To appropriately adjust, when scanning an image of a composite figure expressed by a combination of a predefined figure having a predetermined shape and a free-form figure freely drawn, a position and a shape between the free-form figure and the predefined figure.SOLUTION: In the present invention, a figure included in an input image is separated into a predefined figure and a free-form figure. For the separated predefined figure, a representative point is set at a predetermined position according to the type of the predefined figure, and for the free-form figure, a representative point is set based on a reference corresponding to the type of the free-form figure. If the set representative point of the predefined figure is in the vicinity of the set representative point of the free-form figure, the representative point of the free-form figure and the representative point of the predefined figure are grouped, and based on the position of the grouped representative point of the free-form figure and the position of the grouped representative point of the predefined figure, the free-form figure is corrected.
【課題】 予め定められた形状の既定図形と、自由に作図した自由図形とを組み合わせで表現されている合成図形の画像をスキャンした場合に、自由図形と既定図形との間の位置や形状を適切に調整する。 【解決手段】 本発明では、入力画像に含まれる図形を、既定図形と自由図形とに分離する。当該分離された既定図形に対して、当該既定図形の種類に応じて予め定められた位置に代表点を設定し、自由図形に対して、当該自由図形の種類に応じた基準に基づいて、代表点を設定する。当該設定された自由図形の代表点の近傍に前記設定された既定図形の代表点があれば、当該自由図形の代表点と当該既定図形の代表点とをグループ化し、グループ化された自由図形の代表点の位置と当該グループ化された既定図形の代表点の位置とに基づき、自由図形の方を補正する。 【選択図】 図14
