Description of the Invention: [Technical Field] The present invention relates to a photographic technique, and more particularly to a reversing photography system. [Prior Art] With the development of technology and the continuous improvement of people's lives, cars have entered the lives of many people. Safe driving a car has become a growing concern. Previously, when driving a car, the rear view method relied mainly on the rear view mirrors mounted on the front sides of the car. Under the condition of the car rear view device, the rear part of the car body belonged to the “blind zone” of the driver. However, when the driver respects the car, he wants to understand the blind spot on both sides of the car. In this case, it is necessary to turn around and look at the rear view mirrors on both sides. This is easy to happen because it is not timely and clearly understood from the rearview mirror. The real situation of the car (4) into the judgment of the mistake 'has carried out the wrong driving operation, and thus may cause serious consequences. ^ Objective:, the reversing monitoring device used on the L gas car, from the initial reversing after the child, brother, pick up Down to the voice prompts, followed by the mining, car radar, and later further launched the camera in the fixed position of the car, resulting in [invention] caused a smaller viewing angle. The system has a meal here 'need to provide a kind A reversing photography-reversing photography system capable of expanding the viewing angle, comprising: (4) processing and/or cutting and the processor and the power supply device, the power supply device, the driving device, and the camera connected to the display device The photographic device is movably disposed on the lead of the guide 7 201002554. The driving device is drivingly connected to the photographic device, and the processor controls the The driving device drives the photographing device to move along the guiding member, and the processor displays the image captured by the photographing device on the display screen. Compared with the prior art, the above-mentioned reverse photographing system is set by an activity The imaging device on the guide has an enlarged viewing angle. [Embodiment] In order to further explain the reversing camera system of the present invention, the following embodiments will be described in detail below with reference to the accompanying drawings. The reversing camera system 100 of the present embodiment includes a guiding member 110, a camera device 120, a driving device 130, a display screen 140, a processor 150, and a power device 160. The processor 150 includes a The image control unit 151. The image capturing device 120, the driving device 130, and the display screen 140 are electrically connected to the processor 150 and the power supply device 160. The power device 160 is the camera device 120. The driving device 130, the display screen 140 and the processor 150 provide power. It can be understood that the display screen 140 is installed in the car. The guiding device 110 can be disposed at any position of the tail of the automobile. Referring to FIG. 2, the camera device 120 includes a base 121 and a camera 122. Preferably, the camera includes a wide-angle lens (not shown). The base 121 cooperates with the guiding member 110 and can slide on the guiding member 110. A through hole 121a is defined in the base 121 along the axis of the guide member 110 201002554. It can be understood that In order to protect the camera 122 of the camera device 120, the camera device 120 has a waterproof housing (not shown) that can be opened and closed. The waterproof housing is in a closed state before the photographing function is activated. In the vicinity of the photographing device 120 of the rear end of the vehicle, the driving device 130 is connected to the photographing device 120. In the embodiment, the driving device 130 is a telescopic link 131 made of piezoelectric material, and the connecting rod 131 is bent. Fold into "L" type. Specifically, one end of the connecting rod 131 is in an interference fit with the through hole 121a, and one end of the connecting rod 131 is fixed on the guiding member 110, and one end of the connecting rod 131 is telescopically conductive. The camera device 120 is driven to move along the guide 110. The image control unit 151 is configured to receive an image signal sent by the camera 120 and send it to the display 140. Specifically, the processor 150 can be controlled by an operation button near the display screen 140, the driver presses a button, the reverse photography system 100 is activated, and the processor 150 controls the driving device 130 to drive the camera. < the shadow device 120 moves along the guide member 110 to a desired position, thereby expanding the angle of view, and the image control unit 151 displays the image captured during the movement of the photographing device 120 on the display screen 140, so that The driver can understand the specific situation behind the car by looking at the display screen 140. Second Embodiment Referring to FIG. 3 , a reverse photography system 100 ′ provided by the present embodiment is basically the same as the reverse photography system 100 in the first embodiment, except that the processor 150 ′ further includes a steering control unit 152 ′. And a gear unit 9 201002554 sensing unit 153'. The steering control unit 152' is configured to generate a steering signal according to the direction of the steering of the automobile steering wheel, and send the driving signal to the driving device 130', so that the driving device 130' drives the imaging device 120' to move in the direction of the steering signal indication. . The gear position signal sensing unit 153' is configured to receive the signal of the car gear and transmit it to the steering control unit 152 of the processor 150'. Specifically, if the gear position signal sensing unit 153 ′ receives the signal that the vehicle gear position is the reverse gear, the signal of the reverse gear is input to the steering control unit 152 ′ of the processor 150 ′, the steering control unit 152 ' Further determining the direction of reversing, if the reversing direction is the left rear of the car, the steering control unit 152' transmits the direction to the driving device 130', which drives the camera device 120' to move along the guiding member 110' To the left of the guiding member 110' (to the left of the direction of the car), and to capture the image at that position, the image control unit 15 displays the captured image on the display screen 140'; The direction is the rear of the car, and the steering control unit 152' sends the direction to the driving device 130'. The driving device 130' drives the camera device 120' to move along the guiding member 110' to the middle of the guiding member 110'. And capturing the image at that time, the image control unit 151' displays the captured image on the display screen 140'; if the direction of the reverse is the right of the car The steering control unit 152' transmits the direction to the driving device 130', and the driving device 130' drives the camera device 120' to move to the right of the guiding member 110' along the guiding member 110' (the right direction of the car in the forward direction) The image control unit 15 displays the captured image on the display screen 140'. 201002554 The above-mentioned reversing camera system 100' expands the angle of view by the camera device 120' disposed on the guiding member 110', and the gear position signal sensing unit 153' and the steering control unit 152' work together to realize Automated control, <In addition, the reversing camera system 100M is activated in the reverse state to achieve the effect of the section _ energy, and is started in the non-reverse state to realize real-time monitoring.
