Abstract

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.

Claims

1. An electronic control unit that executes data processing to shape a video image of a peripheral area of a vehicle body that is captured by a camera so as to display the shaped video image on a monitor, comprising a video image shaping means configured to display the video image data received by the camera on at least two portions of a screen of the monitor at different compression ratios.

2. The electronic control unit according to claim 1, wherein

the video image shaping means includes a video image processing circuit that changes the compression ratios of the video images that are displayed on at least the two portions of the screen of the monitor according to vehicle information.

3. The electronic control unit according to claim 2, wherein

the video image processing circuit processes the video image data that is displayed on at least the two portions of the screen of the monitor so that the compression ratios differ in a horizontal direction.

4. The electronic control unit according to claim 2, wherein

the video image processing circuit processes the video image data that is displayed on the two portions of the screen of the monitor so that the compression ratios differ in a vertical direction.

5. An in-vehicle video system comprising:

a camera that captures a video image of a peripheral area of a vehicle body;

a monitor that displays thereon video image data captured by the camera; and

an ECU that executes a data processing to shape a video image that is to be displayed on the monitor,

wherein the ECU comprises a video image processing circuit that changes compression ratios of a video image that is displayed on at least two portions of a screen of the monitor according to vehicle information.
