description To enable the reading of an indication value of an indication needle instrument by suppressing a calculation amount and a memory usage amount required for image processing.SOLUTION: According to the present invention, an image processing device for deriving an indication value of an indication needle instrument from a picked-up image obtained by photographing a display surface of the indication needle instrument includes: a projective transformation part for using a projective transformation parameter between a virtual reference image of the indication needle instrument and an image of the indication needle instrument in the inputted picked-up image to projectively transforming an indication needle detection coordinate sequence having a plurality of coordinate values showing positions of an indication needle of the indication needle instrument in the reference image or the picked-up image; an indication needle detection part for detecting the position of the indication needle from a plurality of pixel values extracted from the picked-up image by using the projectively transformed indication needle detection coordinate sequence or a plurality of pixel values extracted from a picked-up image projectively transformed by using the indication needle detection coordinate sequence; and an indication value derivation part for deriving an indication value corresponding to the position of the indication needle detected by the indication needle detection part.SELECTED DRAWING: Figure 1 【課題】画像処理に要する計算量およびメモリ使用量を抑えて、指示針計器の指示値を読み取ることができるようにする。【解決手段】本発明は、指示針計器の表示面を撮影した撮像画像から指示針計器の指示値を導出する画像処理装置において、指示針計器の仮想的な基準画像と、入力された撮像画像中の指示針計器の画像との射影変換パラメータを用いて、基準画像で指示針計器の指示針の位置を示す複数の座標値を有する指示針検出座標列、若しくは、撮像画像を射影変換する射影変換部と、射影変換された指示針検出座標列を用いて撮像画像から抽出した複数の画素値、若しくは、指示針検出座標列を用いて射影変換された撮像画像から抽出した複数の画素値から、指示針の位置を検出する指示針検出部と、指示針検出部より検出された指示針の位置に対応する指示値を導出する指示値導出部とを備える。【選択図】 図1
