An in-vehicle video system includes cameras that capture rear and side areas of a vehicle body, monitors that display video images captured by the cameras on screens thereof, and an ECU that shapes the video images that are displayed on the monitors. The cameras are accommodated in housings that are provided on left and right sides of a vehicle body, and side turn signal lamps are provided individually on external surfaces of the housings. The ECU controls a video image processing circuit so that the video images of the rear and side areas of the vehicle body are displayed on two portions of the screen of the monitor at different compression ratios and that the compression ratios change according to vehicle information.
