PROBLEM TO BE SOLVED: To generate an image suitable for observation while simplifying a structure. SOLUTION: A medical control device 9 causes an image pickup device 521 to image normal light through an observation target in a first period to generate a first captured image, and also passes through the observation target in a second period. The image pickup control unit 942 that captures the excitation light and the fluorescence from the observation target excited by the excitation light with the image sensor 521 to generate a second image, and the excitation light included in the second image. An adjustment process execution unit 933 that executes an adjustment process for deleting components, and a superimposed image generation unit 934 that superimposes a second captured image after the adjustment process is executed on the first captured image to generate a superimposed image. To be equipped. [Selection diagram] Fig. 2【課題】構造の簡素化を図りつつ、観察に適した画像を生成すること。【解決手段】医療用制御装置９は、第１の期間に観察対象を介した通常光を撮像素子５２１にて撮像させて第１の撮像画像を生成させるとともに第２の期間に観察対象を介した励起光と励起光によって励起された観察対象からの蛍光とを撮像素子５２１にて撮像させて第２の撮像画像を生成させる撮像制御部９４２と、第２の撮像画像に含まれる励起光の成分を削除する調整処理を実行する調整処理実行部９３３と、第１の撮像画像に調整処理が実行された後の第２の撮像画像を重畳して重畳画像を生成する重畳画像生成部９３４とを備える。【選択図】図２
