Monitor device for moving body
First Claim
1. A monitor device for displaying a front scene of a moving body, comprising:
- an image forming section for forming a two dimensional image of the front scene on a image plane;
an image sensor for photo-electrically converting the two dimensional image into electric image data;
a speed sensor for detecting running speed of the moving body;
a zoom ratio determining section for determining a zoom ratio in accordance with the detected running speed;
an image area selecting section for processing the image data to select, in accordance with the determined zoom ratio, an area of the image formed by the image forming section;
an image enlarging section for processing the image data processed by the image area selecting section to enlarge the image of the selected area with the zoom ratio determined by the zoom ratio determining section; and
a display for displaying the image of the area enlarged by the image enlarging section.

Abstract
Disclosed is a monitor device for a moving body such as a vehicle, aircraft or vessel, moving at a certain speed. The monitor device displays an image of a front scene of the moving body with the image of the central area being enlarged in accordance with the running speed of the moving body such that condition of a far away portion can be recognized accurately. A zoom ratio calculating section determines a zoom ratio in accordance with running speed of the moving body. The area of image to be displayed is selected in accordance with the zoom ratio and the image of the selected area is displayed on a display screen in an enlarged form. A specially designed distortion lens may be used to take the picture of the front scene to form an image of the scene with its central area being optically enlarged.
