Image processing apparatus and image processing method

Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 例えば、最近隣内挿法を使用する場合、非常 に簡易な構成で実現できる利点があるが、画素の繰り返 し処理を行うため濃度レベルが急激に変化する境界部分 がブロック状に目立ってしまう課題があった。 【解決手段】 原画素が属するエッジ領域の傾斜方向を 示す傾斜情報を原画素と補間画素にマッピングし、拡大 後のディジタル画像を構成する画素毎に当該画素の傾斜 情報に対応するフィルタ処理を実行する。 (57) [Summary] [Problem] For example, when the nearest neighbor interpolation method is used, there is an advantage that it can be realized with a very simple configuration, but a boundary portion where the density level changes rapidly due to the repetition of pixels is processed. However, there was a problem that it was conspicuous in a block shape. SOLUTION: The inclination information indicating the inclination direction of the edge area to which the original pixel belongs is mapped to the original pixel and the interpolation pixel, and a filtering process corresponding to the inclination information of the pixel is executed for each pixel constituting the enlarged digital image. I do.
