In the medical observation device according to the present invention, an image pickup unit that captures a subject at a first angle of view and an image of the first angle of view captured by the image pickup unit are captured by a second image that is smaller than the first angle of view. It includes an image generation unit that generates a display image signal by cutting out at a corner and performing image processing. According to this medical observation device, hand eye coordination and resolution can be maintained even when the field of view is changed.本発明に係る医療用観察装置は、第１の画角で被写体を撮像する撮像部と、撮像部が撮像した第１の画角の画像を、第１の画角よりも小さい第２の画角で切り出して画像処理を施すことによって表示画像信号を生成する画像生成部と、を備える。この医療用観察装置によれば、視野を変えた場合であっても、ハンドアイコーディネーションおよび解像度を維持することができる。
