DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram for explaining a split image system for a vehicle disclosed in the present specification; FIG.

1, the vehicle image segmentation system includes an image acquisition unit 110 including a traveling camera module unit 111 for acquiring a traveling image of a vehicle and a backward camera module 112 for acquiring a backward image of the vehicle, A display unit 130 for displaying an image obtained by the obtaining unit 110 and a driving unit 130 for controlling the driving unit 130 to output a driving image to the display unit 130. When the vehicle is moving backward, And a control unit 120 for controlling the output unit 120 to output the output signal. That is, the control unit 120 displays an image during driving and backward of the vehicle. When the vehicle is moving backward or backward (when the vehicle gear is located at the backward position R) The backward image is displayed. The traveling image can be displayed together with the backward image as described later.

The traveling camera module 111 includes a front camera module 113 for acquiring a forward image of the vehicle, a left camera module 114 for acquiring a left image of the vehicle, a right camera module 115 for acquiring a right image of the vehicle, And a rear camera module 116 for acquiring a rear image of the vehicle. This will be described with reference to FIG.

On the other hand, the left camera module 114 is installed on the left side of the vehicle, and the left image here is not limited to the image in the right-left direction of the vehicle, but includes an image that can be acquired and formed on the left side of the vehicle. Therefore, a rear left image or a front left image can also be included in the left image. The right camera module 115 and the right image are also the same.

2 is a view for explaining an embodiment of a camera module unit located in a vehicle.

Referring to FIG. 2, a total of five camera modules 201, 202, 203, 204, and 205 are installed in the vehicle 200. The traveling camera module unit is divided into a traveling camera module unit 201, a traveling camera module unit 201 and a rearward camera module unit 205. The traveling camera module unit includes a front camera module 201 for acquiring a forward image of the vehicle, A camera module 202, a right camera module 203 for acquiring a right image of the vehicle, and a rear camera module 204 for acquiring a rear image of the vehicle. On the rear side of the vehicle, a rear camera module 204, a backward camera module 205, and two camera modules are installed.

The control unit 140 shown in FIG. 1 outputs a forward image, a left image, a right image, and a rear image to the display unit 130 when the vehicle travels, and outputs a backward image to the display unit 130 Can be controlled. In this case, the display unit 130 can divide the forward image, the left image, the right image, and the rear image into four regions in the display region of the display unit 130 during driving. By doing so, it is possible to check the information on the driving at a glance by outputting the image of the forward direction of the vehicle to the display unit 130 while driving, so that the backward image can be confirmed during the reverse (including parking) .

The control unit 140 may control the backward image to be output to the area of any one of the forward image, the left image, the right image, and the rear image output to the display unit 130 when the vehicle is backward. For example, the image of the region of one of the front image, the left image, the right image, and the rear image, which is displayed at the time of driving, is turned off, the backward image is turned on, can do. By doing so, the running image is displayed in three areas of the four-divided area of the display unit 130, and the backward image is displayed in the remaining one area, so that the driver can see the driving and backward images together.

Preferably, the control unit 140 may control the backward image to be output to the area of the rear image outputted to the display unit 130 when the vehicle is backward. By doing so, the backward image is output to the area displayed on the rear image, thereby providing the driver with the consistency of the position of the image with respect to the backward direction of the vehicle.

The vehicle image segmentation system disclosed in the present specification may further include a storage unit 120 for storing the image acquired by the image acquisition unit 110. [ By doing so, the vehicle image segmentation system simultaneously performs the functions of the vehicle black box. The storage unit 120 may store only the image of the traveling camera module unit 111 or the image of the traveling camera module unit 111 and the image of the backward camera module 112 together. The storage unit 140 can store images of the traveling camera module unit 111 even when a backward image is output to the display unit 130. [

Fig. 3 is a simplified view illustrating an embodiment of a circuit diagram of a vehicle segmented image system disclosed in the present specification.

Referring to FIG. 3, the camera module unit 301 includes a total of five camera modules (ch1 to ch4 and backward). The image obtained by the camera module unit 301 is transmitted to the storage unit 302 and then to the display unit 304 for output. The storage unit 302 stores the image acquired by the camera module unit 301 and turns on the backward camera when the rear gear R is sensed in the gear box 303, As shown in FIG. In the embodiment of FIG. 3, the backward image is stored in the storage unit 302 even while driving. However, depending on the implementation, the backward image may not be stored during the driving.
