To improve dynamic range of ambient light images obtained by a Lidar-type object detection device.SOLUTION: An object detection device 10 includes: a light emitting unit 30; a light receiving unit 20; a period determining unit 100 that determines an ambient light acquisition period for acquiring ambient light according to intensity of ambient light; a light reception control unit 21 that controls a light receiving operation of incident light in the light receiving unit 20; and a light emission control unit 31 that controls a light emission operation of the light emitting unit 30. The light reception control unit 21 causes the light receiving unit 20 to perform the light receiving operation for acquiring ambient light over the ambient light acquisition period determined.SELECTED DRAWING: Figure 2 【課題】ライダー型の物体検出装置によって得られる環境光画像のダイナミックレンジの向上。【解決手段】物体検出装置１０は、発光部３０と、受光部２０と、環境光の強度に応じて環境光を取得する環境光取得期間を決定する期間決定部１００と、受光部２０における入射光の受光動作を制御する受光制御部２１と、発光部３０の発光動作を制御する発光制御部３１とを備える。受光制御部２１は、決定された環境光取得期間にわたり、環境光を取得する受光動作を受光部２０に実行させる。【選択図】図２
