Abstract
Abstract Translated from Japanese (57)【要約】 【課題】 補間による画素数の変換において、斜め線に 対してジャギーの無い補間画像を得ることを目的とす る。 【解決手段】 原画像を2値化し、2値化画像から原画 像に含まれる斜め成分の方向を判定し、その斜め方向へ 補間処理を行うことで、ジャギーの無い補間画像を得る ことができる。 (57) [Summary] [Object] An object of the present invention is to obtain an interpolated image free of jaggies with respect to oblique lines in conversion of the number of pixels by interpolation. SOLUTION: An original image is binarized, a direction of an oblique component included in the original image is determined from the binarized image, and interpolation processing is performed in the oblique direction, thereby obtaining an interpolated image without jaggies. .
