Description

[0001] The present invention relates to a video recording apparatus with a room mirror,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an image recording apparatus for a vehicle, and more particularly, to an image recording apparatus having a built-in room mirror incorporated in a vehicle.

In general, the room mirror is installed in the center of the interior of the vehicle so that the driver can recognize the rearward situation without turning his head.

In addition, there is an increasing need for objective data in order to determine the percentage of negligence caused by accidents caused during the stopping or running of a vehicle. Accordingly, a vehicle image recording device or a black box capable of providing objective data is used , The conventional vehicle black box is installed on the windshield of the vehicle and obstructs the view of the driver. Therefore, in the 10-0830649 (room mirror black box), the black box as the image recording device is built in the room mirror, I proposed a technique that did not interfere.

This conventional technique includes a main body in which a first camera for photographing the front of the automobile, a second and third camera for photographing both sides of the automobile, and a fourth camera for photographing the inside or the rear of the automobile are integrally installed; An infrared image detecting unit installed in the main body and detecting an infrared image incident from a front side; An infrared ray generator for irradiating infrared rays toward the front of the automobile; A display for displaying image information generated by the first, second, third, and fourth cameras and the infrared image detecting unit, the display being installed inside the mirror of the main body; And a central processing unit that is connected to the first, second, third, and fourth cameras, the infrared image detecting unit, and the display unit.

Therefore, the vehicle can be photographed not only in front of the vehicle, but also in both sides and rear, and does not interfere with the driver's view.

However, in this conventional technique, since the viewing angle of the first camera for photographing the most important forward side of the black box is fixed to the main body, if the angle of the room mirror is adjusted according to the posture and the key of the driver, So that the situation of the front of the vehicle can not be accurately recorded.

There is a problem that the function as a black box is lost or limited to some functions.

In order to solve the above problems, the present invention provides a room mirror built-in type image recording apparatus in which an image recording apparatus is built in a room mirror and the angle of the camera is automatically changed to an initially set position when the direction of the room mirror is adjusted It has its purpose.

According to an aspect of the present invention, there is provided a room-mirror-

A room mirror supported by a support in front of a vehicle interior;

And a camera built in the room mirror and having a camera which is exposed to the front surface of the room mirror and photographs the front of the room mirror,

The video recording apparatus

A point irradiating unit located at a front portion of the support and examining a point of light on a specific portion of the front windshield;

A button unit for receiving an input from a user to adjust a photographing angle of the camera;

A signal processing unit for recognizing the position of the point from the image photographed by the camera;

A controller for driving the point irradiating unit according to an input of the button unit and outputting a control signal for adjusting the angle of the camera such that the point is positioned at a specific position of the image, ;

And a fan driving unit and a tilting driving unit for panning or tilting the camera by a control signal of the controller.

In this way, even if the driver adjusts the angle of the room mirror, the camera built in the room mirror always maintains the angle in a constant direction, thereby performing the function of the black box faithfully.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing an external structure of a room mirror incorporating a video recording apparatus according to the present invention; FIG.
2 is a block diagram of a video recording apparatus according to the present invention.
3 is a view for explaining a position where a point is irradiated on a front windshield of a vehicle;
4 is a view showing a state where a point is located at a specific position on an image photographed by a camera;

The present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view showing an external structure of a room mirror incorporating an image recording apparatus according to the present invention, and the room mirror 100 is supported by a support member 110 on the upper side of a vehicle front part of the vehicle so as to be rotatable.

A camera 200 is installed on a front surface of the room mirror 110 and a point irradiating unit 260 is installed on a front portion of the supporting member 110 to irradiate a point on a front windshield of a vehicle .

The direction in which the point is irradiated by the point irradiating unit 260 is the image where the front of the vehicle is best photographed, that is, the specific position of the screen (for example, the central portion of the image I as shown in FIG. 4).

FIG. 2 is a block diagram of a video recording apparatus according to the present invention.

The signal processing unit 210 may process the image photographed by the camera 200 into a signal suitable for storage in the memory 220. However, And provides it to the controller 230.

The controller 230 changes the angle of the camera 200 so that the position of the point recognized by the signal processing unit 210 is positioned at a specific position of the image. And generates a control signal for the tilting driving unit 250 and the tilting driving unit 250.

The operation process of the present invention having such a configuration will be described.

First, when the driver adjusts the room mirror 100 to his / her posture and then inputs a command to adjust the photographing angle of the camera through the button unit 270, the controller 230 controls the point investigation unit 260, A point P in the form of a beam is irradiated to the front windshield FG of the vehicle as shown in FIG. 3. The position of the point P is set such that the front image photographed by the camera 200 is best photographed .

For example, it can be the central part of the photographed image when the camera 200 faces the front.

Since the point irradiating unit 260 is provided on the support 110, it is always irradiated to the same position, and the color of the point P is preferably red or blue so as to facilitate image recognition.

The controller 230 controls the camera 200 and the signal processing unit 210. The image captured by the camera 200 is input to the signal processing unit 210 and is recognized by the image recognition unit 210 as points P ) Is input to the extracted image (I).

At this time, since the position of the room mirror 100 has been changed, the position of the point P is initially shifted from the center rather than the center.

Accordingly, the controller 230 controls the fan driving unit 240 and the tilting driving unit 250 to adjust the photographing angle of the camera 200 by generating a control signal such that the point P is positioned on the center of the image.

The fan driving unit 240 and the tilting driving unit 250 are controlled by continuously inputting the image of the point P photographed from the camera 200 so that the point P is located on the center of the image I, The point irradiation unit 260 is continuously driven until the control is completed.

On the other hand, the structures of the fan driving unit 240 and the tilting driving unit 250 are well known in the art, and are well known in the specification of Japanese Patent Application Laid-Open Nos. 1999-0054128 and 10-1128367.

When the point P is located at the center of the image I as described above, the point irradiating unit 260 is turned off, and the camera 220 and the signal processing unit 210 are controlled so that the forward image is stored in the memory 220 It will be done.
