DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below. Embodiment 1 FIG. FIG. 1 is a block diagram showing a configuration of an in-vehicle display device according to Embodiment 1 of the present invention.
Reference numeral 2 denotes a super display circuit that superimposes a vehicle width mark display position designation signal on a video signal output from the imaging device 1. Reference numeral 3 denotes a viewing angle adjustment circuit. The viewing angle adjustment circuit 3 is output from the super display circuit 2. The video signal is supplied to a liquid crystal display module (hereinafter abbreviated as LCD module) 4 as a display device, and the viewing angle of the LCD module 4 is adjusted. Reference numeral 5 denotes a memory in which characteristics of a vehicle width, an image pickup device mounting angle, and a steering wheel angle (vehicle curve characteristics) are stored in advance corresponding to the vehicle type, and 6 is input vehicle type information from outside, and stores a vehicle width corresponding to the vehicle type. 5 is a controller for controlling the super display circuit 2 and the viewing angle adjustment circuit 3.

Next, the operation will be described. The image pickup device 1 displays an image signal of the periphery of the rear portion of the vehicle body,
To supply. When the vehicle type information is given, the control unit 6 reads out the stored contents of the memory 5 and outputs a vehicle width mark display position designation signal and a viewing angle adjustment voltage signal that match the given vehicle type information.

The super display circuit 2 supplies an image signal obtained by superimposing the vehicle width mark display position designation signal to the viewing angle adjustment circuit 3. The viewing angle adjustment circuit 3 converts the given image signal into LC
An optimum viewing angle signal (VCOM signal) is output to the LCD module 4 according to the viewing angle adjustment voltage signal supplied to the D module 4 and supplied from the control unit 6. The LCD module 4 automatically adjusts the viewing angle according to the given optimum viewing angle signal (VCOM signal), and displays the image 11 and the vehicle width mark 12 of the imaging device 1 as shown in FIG.

When the steering wheel is turned greatly when the vehicle is moving backward, the control unit 6 reads out the characteristic value of the steering wheel angle corresponding to the type of the vehicle from the memory 5 based on the output from the steering wheel angle sensor. The vehicle width mark display position designation signal is changed and controlled based on the value, and the display state of the vehicle width mark 12 is changed as shown in FIG. As a result, the driver can know the direction of the vehicle before moving, and can ensure the safety of driving at the time of backing.

As described above, according to the first embodiment, when the vehicle type is set, the vehicle width mark 12 corresponding to the set vehicle type is automatically displayed. In other words, if the vehicle width mark 12 corresponding to each vehicle type is stored in the memory in advance, the optimum vehicle width mark is automatically set by simply selecting the vehicle type, regardless of the type of the vehicle-mounted display device. 12 can be displayed. Further, the viewing angle suitable for the vehicle type is automatically selected and set according to the set vehicle type, so that there is no need to manually set the viewing angle.

The same parts as those in FIG. 1 are denoted by the same reference numerals, and redundant description will be omitted. In FIG. 5, reference numeral 7 denotes an image recognizing unit constituted by a microcomputer or the like, which recognizes a captured image around the rear part of the vehicle body input from the image capturing apparatus 1. For example, if the vehicle is on a slope from the middle of the road where the vehicle should be backed up, the image recognition unit 7 analyzes the image at the image level captured from the imaging device 1 to determine the distance from the vehicle position and the slope of the slope. The angle is calculated and transmitted to the control unit 6 as analysis data.

In the above analysis, for example, a road and its surroundings or a road and an obstacle are identified based on differences in material, surface gloss and the like by a contour (edge) extraction method. By making a comparison, it is determined whether or not the vehicle comes into contact with the vehicle, and the result of the determination is sent to the control unit 6 as analysis data. The control unit 6 calculates coordinates for displaying the vehicle width marker based on the analysis data, and sends a display command to the super display circuit 2. According to the display command sent, the super display circuit 2 as shown in FIG.
The display state of the vehicle width mark 12 is changed like a vehicle width mark 13 following the captured image 11.

The image recognizing unit 7 is based on the video captured from the image pickup apparatus 1 and the marker data from the control unit 6,
As shown in FIG. 7, the shape, size, distance, and the like of the obstacle 14 that comes into contact with the vehicle are analyzed, and the coordinates and the shape data are sent to the control unit 6. The control unit 6 receives this, creates obstacle display data, and sends it to the super display circuit 2. The super display circuit 2 follows the obstacle display data and outputs the obstacle 1
4 is highlighted in, for example, red.

If a three-dimensional shape (left, right, up, down, etc.) of the vehicle body is displayed on the screen, for example, in a garage or the like based on the video captured from the imaging device 1 and the marker data from the control unit 6, For example, it is also possible to determine whether or not to hit a lamp or the like suspended from the ceiling in the garage (the user may make a determination on the screen without performing image recognition).

As described above, according to the second embodiment, by recognizing the image of the rear periphery of the vehicle taken by the image pickup device, the display state of the vehicle width mark can be changed based on the image recognition result. In addition, since the obstacle to the vehicle in the area where the vehicle is to be backed can be displayed, driving safety when the vehicle is backed can be easily secured. When various options (a front bumper guard, a carrier installed on the ceiling of the vehicle, and the like) are provided, the vehicle width mark may be changeable.
