Description

Technical Field

[0001] The present invention relates to a video sharing system, and more particularly to a video sharing system integrating an electronic rearview mirror and a drive recorder.

Background Art

[0002] In the installation of a conventional drive recorder on a vehicle, a front camera is installed inside the front windshield of the vehicle, and a first rear camera is installed on the rear windshield or the rear part of the vehicle to obtain the front and rear views of the vehicle. Further, the drive recorder needs to be separately connected to a display device for the user to confirm whether the operating state and the shooting field of view are as desired.

[0003] In recent years, electronic rearview mirrors are becoming popular. When installing the electronic rearview mirror, it is necessary to install a second rear camera dedicated to the electronic rearview mirror at the position of the rear windshield of the vehicle. Since these rear cameras have similar functions and their installation positions are close to each other, users have concerns about the overlapping installation of rear cameras. In addition, the electronic rearview mirror is a display device for displaying the video of the second rear camera, and the display device connected to the drive recorder also has similar functions in terms of confirming the operation of each camera and the shooting field of view.

[0004] Furthermore, laying a plurality of wirings behind the vehicle not only complicates the wiring configuration and increases the difficulty of installation work, but also the interference generated by individually supplying power to a plurality of devices may have an adverse effect on the imaging quality of each camera and the operation stability of the drive recorder and the electronic rearview mirror.

[0005] As described above, in the prior art, when installing a drive recorder and an electronic rearview mirror at the same time, a plurality of rear cameras and a plurality of display devices are required, so there is a need for a new system to improve these problems.
