Zusammenfassung: | PROBLEM TO BE SOLVED: To apply processing for sharpening to warped images according to the extent of deformation in each individual area.SOLUTION: An image correcting device (10) comprises a sharpening filter (15) and an interpolation processor (13). The characteristics of the sharpening filter (15) are determined by the distance between the coordinates on an input image corresponding to the coordinates of an object pixel in an output image and the coordinates on the input image corresponding to the coordinates of pixels around the object pixel. The interpolation processor (13) takes as the pixel value of the object pixel a value obtained by applying the sharpening filter (15) on an interpolated value interpolated on the basis of the pixel value of each pixel around the coordinates on the input image corresponding to the coordinates of each object pixel.SELECTED DRAWING: Figure 1
【課題】ワーピング後の画像に対して各領域の変形の程度に応じた鮮鋭化処理を施す。【解決手段】画像補正装置(10)は、鮮鋭化フィルタ(15)と補間処理部(13)とを含む。鮮鋭化フィルタ(15)は、出力画像における対象画素の座標に対応する入力画像上の座標と、対象画素の周辺の画素の座標に対応する入力画像上の座標との距離に応じて特性が定まるものである。補間処理部(13)は、対象画素毎に、対象画素の座標に対応する入力画像上の座標の周辺の各画素の画素値に基づいて補間した補間値に対して鮮鋭化フィルタ(15)を施した値を、対象画素の画素値とする。【選択図】図1 |
