PROBLEM TO BE SOLVED: To observe an affected part in a more preferable manner even under a situation where the state of the affected part changes with time series. SOLUTION: The first image is based on a plurality of first captured images output from an imaging unit according to the imaging results of light belonging to a first wavelength band at a plurality of different timings with the affected area as a subject. Corresponds to the imaging result of the estimation unit that estimates the movement of the affected area in the captured image of the above and the light output from the imaging unit that belongs to the second wavelength band at a plurality of different timings with the affected area as the subject. A medical image processing apparatus including a difference extraction unit that extracts a difference between a plurality of second captured images based on an estimation result of movement of the affected area. [Selection diagram] Fig. 1【課題】患部の状態が時系列に沿って変化するような状況下においても、当該患部をより好適な態様で観察可能とする。【解決手段】撮像部から出力される、患部を被写体とした互いに異なる複数のタイミングでの第１の波長帯域に属する光の撮像結果に応じた複数の第１の撮像画像に基づき、当該第１の撮像画像中における当該患部の動きを推定する推定部と、撮像部から出力される、前記患部を被写体とした互いに異なる複数のタイミングでの第２の波長帯域に属する光の撮像結果に応じた複数の第２の撮像画像間の差分を、前記患部の動きの推定結果に基づき抽出する差分抽出部と、を備える、医療用画像処理装置。【選択図】図１
