To make it possible to appropriately illuminate an imaging range of a wide-angle imaging device while preventing an increase in size of a projector.SOLUTION: In a projector 12, under a configuration where a plurality of LEDs 23 are used in which a radiation angle range having a radiant intensity of 50% or more is narrower than a range corresponding to the angle of view in the horizontal direction of an imaging device 11, these LEDs 23 are arranged at positions to be outside the angle of view of the imaging device 11, and are set in a direction to cover the angle of view at least in the horizontal direction of the imaging device 11 with the LEDs 23.SELECTED DRAWING: Figure 1 【課題】投光器の大型化を抑制しつつ、広角の撮影デバイスの撮影範囲を適切に照明可能にする。【解決手段】投光器１２は、５０％以上の放射強度を有する放射角度範囲が、撮影デバイス１１の水平方向の画角に対応する範囲よりも狭い複数のＬＥＤ２３を用いた構成の下、これらＬＥＤ２３は、撮影デバイス１１の画角外となる位置に配置され、かつ、各ＬＥＤ２３によって撮影デバイス１１の少なくとも水平方向の画角をカバーする向きに設定される。【選択図】図１
