PROBLEM TO BE SOLVED: To improve convenience of a user by outputting an image of a region of an affected part and the like after fog correction processing even with display delay, when fog is generated, and on the other hand, by outputting a high picture quality image of a region of an affected part and the like without fog correction processing when fog is not generated, according to an imaging condition of the affected part.SOLUTION: In an endoscope system 5, in the case where fog is not generated in an affected part, a camera control unit 15, according to a state of a head switch 19, performs normal correction processing with respect to an image imaged by an endoscope. In the case where fog is generated in the periphery of the affected part by laser ablation and the like, a user operates the head switch 19 to ON, and performs instruction with respect to the camera control unit 15 so as to switch to perform fog correction processing with respect to the image imaged by the endoscope 10. In the case where fog correction processing is performed, compared to normal correction processing, display delay of equal to or more than one frame occurs to the image of the affected part displayed on a monitor 16, however, a situation where the affected part becomes invisible due to the fog can be avoided, and the user can continue surgery without interruption.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】患部の撮像状況に応じて、霧が発生している時には表示遅延があっても霧補正処理後の患部等の部位の画像を出力し、一方、霧が発生していない時には霧補正処理なしの患部等の部位の高画質な画像を出力し、ユーザの利便性を向上する。【解決手段】内視鏡システム5では、患部に霧が発生していない場合、カメラ制御装置15は、ヘッドスイッチ19の状態に応じて、内視鏡で撮像される画像に対し通常補正処理を行う。レーザ切除等により患部周辺に霧が発生した場合、ユーザはヘッドスイッチ19をオンに操作し、カメラ制御装置15に対し内視鏡10で撮像される画像に対し霧補正処理を行うように切り替える指示を行う。霧補正処理を行った場合、通常補正処理と比べ、モニタ16に表示される患部の画像に1フレーム分以上の表示遅延が生じるものの、霧で患部が視えなくなるような状況は回避され、ユーザは手術を中断することなく続行できる。【選択図】図1
