Zusammenfassung:To provide an image processing device capable of improving edge extraction accuracy while suppressing the processing load.SOLUTION: An image processing device in an embodiment includes an acquisition unit and a generation unit. The acquisition unit acquires image data. The generation unit is configured to generate interpolated pixels assigned to pixels that do not exist in the image data based on peripheral pixels when generating a corrected image with a distortion corrected in image data acquired by the acquisition unit. The generation unit is also configured to displace a weight of each peripheral pixel included in the interpolation pixel from a weight in ideal coordinates to interpolation pixels.SELECTED DRAWING: Figure 2 【課題】処理負荷を抑えつつ、エッジの抽出精度を向上させること。【解決手段】実施形態に係る画像処理装置は、取得部と、生成部とを備える。取得部は、画像データを取得する。生成部は、取得部によって取得された画像データに含まれる歪みを補正した補正画像の生成時において、画像データに存在しない非実在画素に割り当てる補間画素を周囲画素に基づいて生成する。また、生成部は、補間画素に含まれる周囲画素それぞれの重みを補間画素を補間する理想座標における重みからずらす。【選択図】図2
