PROBLEM TO BE SOLVED: To provide a vehicle number reading device capable of accurately reading a vehicle number of an automobile in accordance with a lighting state of headlights of a traveling automobile.SOLUTION: A vehicle number reading device includes: an imaging section for imaging a range including a first imaging range and a second imaging range; and a control section. The control section changes an imaging condition of the imaging section in accordance with a lighting state of headlights of an automobile included in a first captured image obtained by capturing a first imaging range by the imaging section, and reads a vehicle number of an automobile included in a second captured image obtained by capturing the second imaging range by the imaging section with the use of the changed imaging condition.SELECTED DRAWING: Figure 5

    【課題】走行中の自動車のヘッドライトの点灯状態に応じて当該自動車の車両番号を精度よく読み取ることができる車両番号読取装置を提供すること。【解決手段】車両番号読取装置は、第1撮像範囲と第2撮像範囲とを含む範囲を撮像する撮像部と、制御部と、を備え、制御部は、撮像部により第1撮像範囲が撮像された第1撮像画像に含まれる自動車のヘッドライトの点灯状態に応じて撮像部の撮像条件を変更し、変更された撮像条件を用いて撮像部により第2撮像範囲が撮像された第2撮像画像に含まれる自動車の車両番号を読み取る。【選択図】図5
