PROBLEM TO BE SOLVED: To improve the estimation accuracy of the movement amount of a subject.SOLUTION: A mutual correlation analysis part 114 analyzes mutual correlation between a first image and a second image obtained by imaging the same subject as that of the first image before the first image. A first movement estimation part 211 estimates a first movement amount corresponding to the moving blur of the first image. On the basis of a result of the analysis of the mutual correlation and a result of the estimation of the first movement amount, a second movement estimation part 212 estimates a second movement amount between the first image and the second image that is different from the first movement amount.SELECTED DRAWING: Figure 8【課題】被写体の動き量の推定精度を向上させる。【解決手段】相互相関解析部１１４は、第１の画像と第１の画像より前に第１の画像と同じ被写体を撮影した第２の画像との相互相関解析を行い、第１の動き推定部２１１は、第１の画像の動きボケに対応する第１の動き量を推定し、第２の動き推定部２１２は、相互相関解析の結果、及び、第１の動き量の推定結果に基づいて、第１の動き量とは異なる、第１の画像と第２の画像との間の第２の動き量を推定する。【選択図】図８
