4 補間処理手段
Claims (2)
- 光学系の歪曲収差による画像歪みを補正する画像歪み補正装置であって、
各画素毎の輝度成分と複数画素毎に間引かれる色差成分からなるディジタルの入力画像信号を順次記憶する記憶手段と、記憶手段に記憶した入力画像信号を読み出して画像歪みによる位置ずれを修正するための座標変換を行う座標変換手段と、座標変換手段で座標変換された入力画像信号の輝度成分並びに色差成分に対して画素値の補間処理を行う補間処理手段とを備え、
補間処理手段は、画像の中心を含む所定範囲内の座標の画素値を当該座標の近傍の座標における画素値から線形近似した画素値で補間する処理を行い、前記所定範囲外の座標の画素値を当該座標の近傍の座標における画素値で補間する処理を行うことを特徴とする画像歪み補正装置。 - 記憶手段は、座標変換手段で変換される前の座標と変換後の座標との差の絶対値の最大値に応じた数の画素値を記憶することを特徴とする請求項1記載の画像歪み補正装置。
