PROBLEM TO BE SOLVED: To provide a video signal compression apparatus for properly transmitting a video signal of a display screen including a medical image through a communication network.SOLUTION: A video signal compression apparatus includes: a video signal compression unit 62 for compressing a video signal A1 for displaying an image inspection screen including a first region for displaying a medical image and a second region for displaying information other than the medical image on an image inspection monitor； and a transmission unit 63T for transmitting the compressed video signal A1 through a communication network N. The video signal compression unit 62 compresses the second region of the image inspection screen at a compression rate higher than a compression rate for the first region in each frame of the video signal A1.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2020,JPO&INPIT【課題】医用画像を含む表示画面の映像信号を、通信ネットワークを介して適切に送信する映像信号圧縮装置を提供する。【解決手段】医用画像を表示する第１領域と、医用画像以外の情報を表示する第２領域と、を含む検像画面を検像用モニタに表示する映像信号Ａ１を圧縮する映像信号圧縮部６２と、圧縮された映像信号Ａ１を、通信ネットワークＮを介して送信する送信部６３Ｔと、を備え、映像信号圧縮部６２は、映像信号Ａ１の各フレームにおいて検像画面の第２領域を、第１領域に対する圧縮率よりも高い圧縮率で圧縮する構成とした。【選択図】図３
