To appropriately perform foreign object detection and positioning between an electric power transmission unit and an electric power reception unit in an electric power transmission device that uses a photographing device to perform the foreign object detection and the positioning between the electric power transmission unit and the electric power reception unit depending on the situation.SOLUTION: A control unit 140 of an electric power transmission device 100 is configured to use a picture photographed with a camera 120 to perform: positioning processing in which positioning between an electric power transmission unit 110 and an electric power reception unit 212 is performed; and foreign object detection processing for detecting whether or not a foreign object is present between the electric power transmission unit 110 and electric power reception unit 212. The control unit 140 operates in a positioning preferential mode in which the positioning processing is performed preferentially than the foreign object detection processing, before start of power transmission; and operates in a foreign object detection preferential mode in which the foreign object detection processing is performed preferentially than the positioning processing, during performing of the power transmission.SELECTED DRAWING: Figure 1
【課題】撮影装置を用いて異物検知及び送電部と受電部との位置合わせを行なう送電装置において、異物検知及び位置合わせを状況に応じて適切に実行する。【解決手段】送電装置100の制御部140は、カメラ120により撮影される画像を用いて、送電ユニット110と受電ユニット212との位置合わせを行なう位置合わせ処理、及び、送電ユニット110と受電ユニット212との間に異物が存在するか否かを検知する異物検知処理を実行するように構成される。制御部140は、送電が開始される前は、位置合わせ処理を異物検知処理よりも優先して実行する位置合わせ優先モードで作動し、送電の実行中は、異物検知処理を位置合わせ処理よりも優先して実行する異物検知優先モードで作動する。【選択図】図1
