Description

Technical Field

[0001] This utility model is an image sharing system, particularly an image sharing system that integrates an electronic rearview mirror and a dashcam. Background Technology

[0002] Traditional dashcams require a front-facing camera installed inside the windshield and a rear-facing camera installed on the rear windshield or at the rear of the vehicle to capture front and rear views. Additionally, a monitor must be connected to allow the user to check if the dashcam is functioning correctly and if the viewing angles are as needed.

[0003] In recent years, electronic rearview mirrors have become increasingly popular. When installing these mirrors, a second rear camera is required on the rear windshield. Because these rear cameras serve similar functions and are located in similar positions, users may experience confusion regarding their repetitiveness. Furthermore, the electronic rearview mirror is a display device for this second rear camera, and the monitor connected to the dashcam also serves a similar function: confirming whether the cameras are functioning correctly and whether the viewing angles are as desired.

[0004] In addition, deploying multiple lines at the rear of the vehicle not only increases the difficulty of deployment due to the complexity of the wiring, but also causes interference due to the independent power supply of multiple devices. This will not only affect the imaging of these lenses, but also affect the stability of the dashcam and the electronic rearview mirror.

[0005] Because existing technology requires multiple rear cameras and multiple display devices when installing a dashcam and an electronic rearview mirror, a new system is needed to improve the situation. Utility Model Content

[0006] This utility model proposes an image sharing system integrating an electronic rearview mirror and a dashcam, comprising a rear camera device, a dynamic connection device, a dashcam recording device, and a dashcam information device. The dynamic connection device includes a signal connection unit and an image splitting unit. The dashcam recording device includes a front camera unit, a processing unit, and a storage unit. The dashcam information device includes an information output unit. The image splitting unit of the dynamic connection device has an image input terminal, a first image output terminal, and a second image output terminal.

[0007] The image input terminal of the image splitting unit of the dynamic connection device is connected to the rear camera device, the first image output terminal is connected to the signal connection unit, the second image output terminal is connected to the processing unit of the driving recorder, and the processing unit is connected to the front camera unit and the storage unit.

[0008] The rear camera device generates a rear camera image, which is then transmitted by the image splitter to the processing unit and signal connection unit of the dashcam. The processing unit receives the rear camera image and a front camera image from the front camera unit, generates a dashcam image, and stores it in the dashcam's storage unit. The processing unit also transmits the front camera image to the signal connection unit. Upon receiving the front and rear camera image, the signal connection unit transmits it to the driving information device, where it displays the front and rear camera image on the information output unit.

[0009] By utilizing the image splitting unit of this dynamic link device, the dashcam and the vehicle information device can share the rear camera unit, which not only reduces the difficulty of wiring deployment but also reduces interference caused by multiple devices powering the same device. The dashcam and the vehicle information device can also share the information output unit of the vehicle information device to display these images, reducing the need for additional display devices.
