To provide a camera system in which a wide-angle lens camera having projection characteristics at which a peripheral angle of view is high in resolution is installed on an upper part of a movable body, and distortion of a lens peripheral part that is a monitoring area and a low-resolution image are improved.SOLUTION: A camera system has: image acquisition means that acquires an image created by imaging means that is installed to pick up an image of an upper area of a movable body, and picks up an optical image having a high-distortion first area corresponding to an angle of view less than a predetermined angle of view and a second area having lower distortion than the first area corresponding to an angle of view equal to or more than the predetermined angle of view; cut-out angle of view setting means that sets an angle of view to be displayed on a monitor in the image picked up by the imaging means; distortion correction processing means that performs distortion correction processing based on information on the angle of view set by the cut-out angle of view setting means, on a cut-out image obtained by cutting out the angle of view set by the cut-out angle of view setting means; and the monitor that displays the cut-out image on which the distortion correction processing is performed.SELECTED DRAWING: Figure 1
【課題】 移動体の上方に周辺画角が高解像度となる射影特性を有する広角レンズカメラを設置し、監視領域であるレンズ周辺部の歪曲および低解像を改善するカメラシステムに関する。【解決手段】 カメラシステムが、移動体の上方領域を撮像するように設置された撮像手段であって、所定の画角未満の画角に対応する高歪曲な第1の領域と所定の画角以上の画角に対応する前記第1の領域より低歪曲な第2の領域とを有する光学像を撮像する撮像手段により生成した画像を取得する画像取得手段と、前記撮像手段が撮像した画像のうちモニタに表示する画角を設定する切り出し画角設定手段と、前記切り出し画角設定手段で設定された画角の情報に基づく歪曲補正処理を、前記切り出し画角設定手段によって設定された画角を切り出した切り出し画像に対して行う歪曲補正処理手段と、前記歪曲補正された切り出し画像を表示するモニタと、を有する。【選択図】 図1
