Abstract

A front-and-rear-facing camera device has a camera unit mounted on a selected position on a carrier. The camera unit has a front lens and a rear lens oppositely mounted on a lens-mounting base to take a front-view video stream and a rear-view video stream, and displays the front-view and rear-view video streams on two non-overlapping display areas of a display, or displays the front-view video stream on an overlapping display area of the display and the rear-view video stream on the displayed front-view video stream through an image-processing circuit and a signal transmission interface electrically connected between the front and rear lenses and the display.

Claims

1. A front-and-rear-facing camera device, comprising:

a carrier; and

a camera unit mounted on a selected position on the carrier, and having;

a lens-mounting base having;

a base-mounting surface affixed on the selected position on the carrier; and

a front lens-mounting surface and a rear lens-mounting surface formed on two opposite sides of the lens-mounting base;

a front lens mounted on the front lens-mounting surface, having a front shooting angle, and taking a front-view video stream of a surrounding environment within a range of the front shooting angle;

a rear lens mounted on the rear lens-mounting surface, having a rear shooting angle, and taking a rear-view video stream of the surrounding environment within a range of the rear shooting angle;

an image-processing circuit electrically connected to the front lens and the rear lens to receive the front-view video stream and the rear-view video stream;

a signal transmission interface electrically connected to the image-processing circuit; and

a display electrically connected to the image-processing circuit through the signal transmission interface to receive the front-view video stream and the rear-view video stream transmitted from the image-processing circuit and to display the front-view video stream and the rear-view video stream on the display.

2. The front-and-rear-facing camera device as claimed in claim 1, wherein the signal transmission interface is a wireless signal transmission interface or a wired signal transmission interface.

3. The front-and-rear-facing camera device as claimed in claim 1, wherein the front-view video stream and the rear-view video stream are respectively displayed on two non-overlapping display areas of the display.

4. The front-and-rear-facing camera device as claimed in claim 1, wherein the front-view video stream is displayed on an overlapping display area of the display and the rear-view video stream is displayed on the displayed front-view video stream.

5. The front-and-rear-facing camera device as claimed in claim 1, further comprising a waterproof cover covering the front lens and the rear lens.

6. A front-and-rear-facing camera device, comprising:

a carrier; and

a camera unit mounted on a selected position on the carrier, and having;

a lens-mounting base having;

a base-mounting surface affixed on the selected position on the carrier; and

a front lens-mounting surface and a rear lens-mounting surface formed on two opposite sides of the lens-mounting base;

a front lens mounted on the front lens-mounting surface, having a front shooting angle, and taking a front-view video stream of a surrounding environment within a range of the front shooting angle;

a rear lens mounted on the rear lens-mounting surface, having a rear shooting angle, and taking a rear-view video stream of the surrounding environment within a range of the rear shooting angle;

an image-processing circuit electrically connected to the front lens and the rear lens to receive the front-view video stream and the rear-view video stream; and

an image storage module electrically connected to the image-processing circuit to store the front-view video stream and the rear-view video stream.

7. The front-and-rear-facing camera device as claimed in claim 6, further comprising a waterproof cover covering the front lens and the rear lens.
