Apparatus for watching around vehicle
First Claim
1. An apparatus for watching around a vehicle, the apparatus comprising:
- an image pick-up unit, mounted on an exterior of the vehicle, for picking up images of the surroundings of the vehicle;
a display unit, provided within the vehicle, for displaying the images with a mask image superimposed on the images;
a light-to-dark decision unit for deciding lightness outside the vehicle and outputting a light-to dark decision signal;
wherein a display color of the mask image is switchable from one to another; and
the display color of the mask image is set switchable from one to another according to the light-to-dark decision signal from the light-to-dark decision unit.

Abstract
An apparatus for watching around a vehicle comprises an image pick-up unit 3 mounted on the exterior of a vehicle and a display unit 4 provided within the vehicle and used for displaying left and right images of the surrounding of the vehicle thus picked up by the image pick-up unit 3 together with a mask image 16 for dividing the surrounding image into the left and right images. In this case, two kinds of display colors including black and blew may be provided to the mask image 16. Further a photodiode 7 for detecting lightness outside the vehicle is provided. In a case where the luminous intensity outside the vehicle is decided to be high by a luminous intensity signal detected by the photodiode 7, a dark mask image 16 is displayed on the display unit 4, whereas when the luminous intensity outside the vehicle is decided to be low thereby, a light blew mask image 16 is displayed thereon.

5. An apparatus for watching around a vehicle, the apparatus comprising:
-
an image pick-up unit mounted to the vehicle, the image pick-up unit for picking up an image on both left and right sides of the surroundings of the vehicle;
a display unit provided within the vehicle, the display unit for displaying the image on the left and right side, an image control unit including;
an image pick-up unit power switch for turning on and off an operating circuit of the image pick-up unit;
an image output signal switch for turning on and off an image output circuit for converting the image signal from said image pick-up unit and supplying the image signal converted; and
a switch control portion having an upper threshold speed of a vehicle speed for turning on and off the image pick-up unit power switch and a lower threshold speed of the vehicle speed for turning on and off the image output signal switch, wherein the switch control portion turns on the image pick-up unit power switch when it is detected that the vehicle speed reaches the upper threshold speed whild the vehicle speed reduces; and
the switch control portion turns on the image output signal switch when it is detected that the vehicle speed reaches the lower threshold speed when the vehicle speed reduces. - View Dependent Claims (6, 7)

8. An apparatus for watching around a vehicle, said apparatus comprising:
-
an image pick-up unit for picking up an image of a dead angle area around the vehicle;
a display unit for displaying the image from the image pick-up unit;
a distance measuring unit for detecting a distance between the vehicle and each obstacle located to obstruct a view of a driver on at least one side out of both sides of the vehicle during the travel of the vehicle; and
a controller for deciding whether or not the image on the display unit is to be displayed on the basis of the distance detected by the distance measuring unit, the controller for controlling the display unit to turn on or off the image of the obstacle on the display unit according to the decision. - View Dependent Claims (9, 10, 11, 12)
