To provide an image compression device capable of compressing an image with an appropriate compression ratio in various scenes.SOLUTION: An image compression device 110 mounted on a vehicle 10 includes an image acquisition unit 111 that acquires an image captured by a camera 122, a driving information acquisition unit 112 that acquires driving information indicating the driving state of the vehicle, an own vehicle behavior recognition unit 115 that recognizes own vehicle behavior which is vehicle behavior from the driving information, an another-vehicle behavior recognition unit 116 that recognizes the another-vehicle behavior which is another-vehicle behavior from the image, a compression rate setting unit 117 that sets a compression rate of the image according to the own vehicle behavior and the another-vehicle behavior, and a compression unit 118 that compresses the image at the compression ratio set by the compression ratio setting unit.SELECTED DRAWING: Figure 1

    【課題】様々なシーンにおいて適切な圧縮率で画像が圧縮できる画像圧縮装置を提供する。【解決手段】車両10に搭載される画像圧縮装置110は、カメラ122で撮影された画像を取得する画像取得部111と、車両の運転状態を表す運転情報を取得する運転情報取得部112と、運転情報から車両の挙動である自車挙動を認識する自車挙動認識部115と、画像から他者の挙動である他者挙動を認識する他者挙動認識部116と、自車挙動と他者挙動とに応じて画像の圧縮率を設定する圧縮率設定部117と、圧縮率設定部が設定した圧縮率で画像を圧縮する圧縮部118と、を備える。【選択図】図1
