PROBLEM TO BE SOLVED: To reproduce a vascular recognition function equivalent to tacit knowledge of a skilled doctor who quickly recognizes a vascular appearing in a surgical field in real time and with high accuracy, and to notify the location of the vascular appearing on an incision surface for peace of mind. Support the provision of safe surgery. SOLUTION: A vessel recognition device is connected to an image pickup device for imaging a surgical field, and an image input unit for inputting a captured image of the surgical field from the image pickup device and an image captured image based on the input captured image. An image processing unit that recognizes the vessel reflected in the image, and an image output unit that generates a composite image in which the recognized information teaching the vessel is superimposed on the captured image and outputs the generated composite image to the monitor. Be prepared. [Selection diagram] Fig. 1【課題】術野に現れる脈管を一早く認識する熟練医師の暗黙知と同等の脈管の認識機能をリアルタイムかつ高精度に再現し、切離面に現れる脈管の箇所を報知し、安心安全な手術の提供を支援する。【解決手段】脈管認識装置は、術野を撮像する撮像装置と接続され、撮像装置からの術野の撮像画像を入力する画像入力部と、入力された撮像画像に基づいて、撮像画像内に映る脈管を認識する画像処理部と、認識された前記脈管を教示する情報を撮像画像に重畳した合成画像を生成し、生成された合成画像をモニタに出力する画像出力部と、を備える。【選択図】図１
