To provide a camera system for visual recognition around a vehicle that can display a high-quality moving image without loss of immediacy even in a light beam condition where blooming occurs without using an expensive CPU.SOLUTION: In a camera 3 including a lens 5, a variable modulated light device 6, and an imaging device 7, the variable modulated light device 6 can form an optical density distribution in the vertical direction, and exposure adjustment is performed for a portion corresponding to a strong light source causing blooming by adjusting the relative position of the imaging device 7 and the variable modulation light device 6 by first moving means 14 for moving the imaging device 7 in a plane orthogonal to the optical axis 5a of the lens 5 and second moving means 16 for shifting the variable modulation light device 6 vertically in a plane orthogonal to the optical axis 5a of the lens 5.SELECTED DRAWING: Figure 2
【課題】高価格なCPUを用いることなく、ブルーミングが発生するような光線状況においても、即時性を損なわずに高品位な動画像を表示できる車両周辺視認用カメラシステムを提供する。【解決手段】レンズ5と可変調光素子6と撮像素子7とを備えたカメラ3において、可変調光素子6を上下方向で光学濃度分布を形成可能とし、撮像素子7をレンズ5の光学軸5aに直交する面内で移動させる第一の移動手段14と、可変調光素子6をレンズ5の光学軸5aに直交する面内で上下方向にシフト移動させる第二の移動手段16と、により、撮像素子7と可変調光素子6の相対位置を調整することにより、ブルーミングが発生する強い光源に対応する箇所の露光調整を行う。【選択図】図2
