Fig. 2 is a schematic structural diagram of a camera monitoring system 10 according to an embodiment of the present application; fig. 3 is a schematic diagram of a monitor device 300 according to an embodiment of the present application scanning a video image in "lines". Referring to fig. 2 and 3, a camera monitoring system 10 includes: a camera 100, a processor apparatus 200, and a monitor apparatus 300, the processor apparatus 200 including an image signal processor 210, wherein the image signal processor 210 is connected to the camera 100 and the monitor apparatus 300, respectively, the processor apparatus 200 further including: a synchronized clock processor 220, wherein the synchronized clock processor 220 is connected with the camera head 100, the monitor device 300, and the image signal processor 210, respectively, and is configured to transmit a first clock signal to the camera head 100, a second clock signal to the monitor device 300, and a third clock signal to the image signal processor 210, and wherein the first clock signal, the second clock signal, and the third clock signal are synchronized.

As described in the background, fig. 1 is a schematic structural diagram of a camera monitoring system in the prior art. Referring to fig. 1, the conventional camera monitoring system collects and displays images in the following ways: the camera collects video images and transmits the video images to the image signal processor in a frame mode through the image input interface. The image signal processor processes the video image frames, transmits the video image frames to the memory, and the memory stores the video image frames for a period of time and transmits the video image frames to the monitor equipment through the image output interface. Then, the monitor device displays the video image.

However, since the existing camera monitoring system has the first crystal oscillator provided in the camera, the second crystal oscillator provided in the processor device, and the third crystal oscillator provided in the monitor device, and the clock signals provided by the first crystal oscillator, the second crystal oscillator, and the third crystal oscillator are independent, there may be an asynchronous situation during image scanning (i.e., scanning of an image by the camera) and image display (i.e., display of an image by the monitor device) when the camera transmits a video image to the monitor device in the form of a "frame". In order to solve the above problem, in the prior art, a dynamic memory is optionally disposed in a processor device, so as to solve the problem that image scanning at a transmitting end and image display at a receiving end are not synchronized. However, since the video images transmitted in "frames" need to be stored in the memory of the processor device for a certain period of time, there is a delay from the acquisition of the video images to the display of the video images (i.e., the situation around the vehicle displayed by the camera monitoring system is different from the actual situation around the vehicle), which may result in the driver not reacting to the situation around the vehicle in time, thereby increasing the risk of the driver driving the vehicle.

In view of the above, the present application provides a camera monitoring system 10. The camera monitoring system 10 is provided with a synchronous clock processor 220. Wherein the synchronized clock processor 220 is connected to the camera head 100 and the monitor apparatus 300, respectively. And wherein the synchronized clock processor 220 is capable of transmitting a first clock signal to the camera head 100, and transmitting a second clock signal to the monitor apparatus 300 and a third clock signal to the image signal processor 220, and the first clock signal, the second clock signal and the third clock signal are synchronized.

Specifically, the synchronized clock processor 220 in the processor device 200 continuously transmits the first clock signal to the camera head 100, continuously transmits the second clock signal to the monitor device 300, and continuously transmits the third clock signal to the image signal processor 210. And since the first, second, and third clock signals are homologous clock signals (e.g., based on a clock signal provided by the same crystal 240), the first, second, and third clock signals are synchronized (i.e., the first, second, and third clock signals do not deviate from each other due to the accuracy of the crystal, and accumulate over time). Thus, there is no problem that accuracy errors of the clock signal of the camera 100, the clock signal of the processor device 200, and the clock signal of the monitor device 300 are accumulated over time due to the difference of the first crystal oscillator connected to the camera 100, the second crystal oscillator connected to the processor device 200, and the third crystal oscillator connected to the monitor device 300, thereby causing the process of the camera 100 scanning the video image and the process of the monitor device 300 displaying the video image to be asynchronous.

Thus, when the camera monitoring system 10 is turned on, the synchronized clock processor 220 transmits a first clock signal to the camera 110, a second clock signal to the monitor device 300, and a third clock signal to the image signal processor 210. When the camera 100 captures a video image of the surrounding situation of the automobile, the camera 100 scans the video image in the form of "lines" and transmits the video image in the form of an electrical signal to the image signal processor 210 in the processor device 200 through the image input interface 270. The image signal processor 210 converts an electrical signal corresponding to a video image into an image signal corresponding to the video image, processes the image signal, and transmits the image signal to the monitor apparatus 300 through the image output interface 280. Finally, the monitor apparatus 300 scans and displays the video image in the form of "lines". Fig. 3 shows a schematic view of a monitor device 300 scanning a video image in the form of "lines". Referring to fig. 3, the monitor apparatus 300 scans a video image in the form of "lines".

Also, since the camera head 100 receives the first clock signal transmitted by the synchronized clock processor 220, the second clock signal transmitted by the synchronized clock processor 220 received by the monitor apparatus 300, and the third clock signal transmitted by the synchronized clock processor 220 received by the image signal processor 210. The processes of image scanning (i.e., scanning of an image by the camera 100) and image display (i.e., scanning of an image by the monitor apparatus 300) can be performed in synchronization. It is only necessary to perform synchronous debugging on the image sensor 110, the image signal processor 210 and the display 310 in the subsequent process. Thereby greatly reducing the delay from the acquisition of the video image by the camera head 100 to the display of the video image by the monitor apparatus 300.

Optionally, the processor device 200 further comprises: and a crystal 240 connected to the synchronous clock processor 220, wherein the crystal 240 is configured to transmit a fourth clock signal to the synchronous clock processor 220, and wherein the first clock signal, the second clock signal, and the third clock signal are clock signals generated according to the fourth clock signal.

Specifically, as shown in fig. 2, a crystal 240 connected to the synchronous clock processor 220 is also provided in the processor device 200. Wherein the crystal 240 is capable of providing the fourth clock signal to the synchronous clock processor 220. Then, the synchronized clock processor 220 generates a first clock signal transmitted to the camera head 100, a second clock signal transmitted to the monitor device 300, and a third clock signal transmitted to the image signal processor 210 based on the fourth clock signal transmitted from the crystal oscillator 240. The first, second, and third clock signals are synchronized because they are homologous clock signals.

Therefore, the technical effect of providing the camera head 100, the processor device 200 and the monitor device 300 with the same source clock signal by using the crystal oscillator 240 so as to synchronously scan the video image by the camera head 100 and the video image by the monitor device 300 is achieved by the product structure.

Optionally, the processor device 200 further comprises: an H/V signal generator 230, wherein the H/V signal generator 230 is connected to the camera head 100, configured to transmit a line/field synchronization signal to the camera head 100.

Specifically, referring to fig. 2, an H/V signal generator 230 connected to the image signal processor 210 is also provided within the processor device 200. The H/V signal generator 230 can transmit a line synchronization signal to the camera head 100. The line synchronization signal transmitted by the H/V signal generator 230 can make the line scanning frequency in the video camera 100 coincide with the line scanning frequency in the monitor system 300. That is, the process of scanning the video image in the form of "lines" by the camera head 100 is performed in synchronization with the process of scanning the video image in the form of "lines" by the monitor apparatus 300.

Therefore, the technical effect of enabling the process of performing the line scan on the video image by the camera 100 and the process of performing the line scan on the video image by the monitor device 300 to be performed synchronously is achieved by the product structure.

Optionally, the camera 100 comprises: the image sensor 110, wherein the image sensor 110 is connected to the image signal processor 210, is configured to generate an electronic image.

Specifically, referring to fig. 2, the camera head 100 includes an image sensor 110, and the image sensor 110 is connected to an image signal processor 210. When the camera monitoring system 10 is started, the image sensor 110 immediately starts to operate, and transmits a video image corresponding to the surrounding situation of the automobile to the image signal processor 210 in the form of an electrical signal through the image input interface 270.

Therefore, by providing the image sensor 110 in the camera 100, a technical effect of capturing a video image corresponding to the surrounding situation of the vehicle by using the image sensor 110 can be achieved.

Further, the camera 100 provided with the image sensor 110 is mounted on a rear view mirror of an automobile, so as to capture an image corresponding to the surrounding situation of the automobile with a larger field of view.

Alternatively, the monitor apparatus 300 includes: a display 310, wherein the display 310 is connected to the image signal processor 210 and configured to display video images.

Specifically, as shown with reference to fig. 2, a display 310 is provided in the monitor apparatus 300, and the display 310 is connected to the image signal processor 210. The display 310 is used to display a video image corresponding to the surroundings of the automobile.

When the image sensor 110 captures a video image corresponding to the surrounding situation of the vehicle in real time, an electrical signal corresponding to the video image is transmitted to the image signal processor 210 through the image input interface 270. The image signal processor 210 converts an electric signal corresponding to a video image into an image signal corresponding to the video image, processes the image signal, and transmits the image signal to the display 310 through the image output interface 280. And the received video image corresponding to the surrounding situation of the car is displayed by the display 310.

Accordingly, by providing the display 310 in the monitor apparatus 300, a technical effect of displaying a video image corresponding to the situation around the automobile by the display 310 can be achieved.

Optionally, the camera 100 comprises a first serializer 120a, and the processor device 200 comprises a first deserializer 250a, comprising: a first serializer 120a and a first deserializer 250a, wherein the first serializer 120a is connected with the image sensor 110; the first deserializer 250a is connected with the image signal processor 210, the H/V signal generator 230, and the synchronous clock processor 220, respectively; and the first serializer 120a is connected with the first deserializer 250a through a serial cable. Further optionally, the processor device 200 includes a second serializer 260a, and the monitor device 300 includes a second deserializer 320a, wherein the second serializer 260a is connected with the image signal processor 210, the H/V signal generator 230, and the synchronized clock processor 220, respectively; the second deserializer 320a is connected with the display 310; and the second serializer 260a is connected with the second deserializer 320a through a serial cable.

Specifically, referring to fig. 2, a first serializer 120a is further disposed in the camera 100, and a first deserializer 250a is further disposed in the processor device 200. The first serializer 120a is connected to the image sensor 110. The first deserializer 250a is connected to the image signal processor 210, the H/V signal generator 230, and the synchronous clock processor 220, respectively. And the first serializer 120a and the first deserializer 250a are connected by a serial cable.

For example, after the vehicle is started, the synchronous clock processor 220 transmits a first clock signal to the image sensor 110, a second clock signal to the display 310, and a third clock signal to the image signal processor 210, respectively. Wherein the first clock signal, the second clock signal and the third clock signal are synchronized.

Then, the image sensor 110 captures a video image of the surrounding situation of the automobile and transmits an electric signal corresponding to the video image to the first serializer 120a. The first serializer 120a converts the electrical signal into a serial signal and transmits the serial signal to the first deserializer 250a through a serial cable. The first deserializer 250a converts the received serial signal into an electrical signal and transmits the electrical signal to the image signal processor 210 through the image input interface 250.

Further, the image signal processor 210 converts the electrical signal corresponding to the video image into an image signal corresponding to the video image, processes the image signal, and transmits the image signal to the second serializer 260a through the image output interface 280.

Finally, the second serializer 260a converts the image signal into a serial signal and transmits the serial signal to the second deserializer 320a through the serial cable. The second deserializer 320a converts the serial signal into an image signal and transmits the image signal to the display 310. The display 310 displays video images.

Further, since the synchronized clock processor 220 has transmitted the first clock signal to the camera 100, the second clock signal to the image signal processor 210, and the third clock signal to the monitor device 300, respectively, at the time of the initial start of the automobile, the process of the image sensor 110 scanning the video image in the form of "lines" is performed in synchronization with the process of the display 310 scanning the video image in the form of "lines". Therefore, the system delay from the process of recording the video image to the display of the video image in the camera monitoring system 200 can be controlled to be a delay in units of line exposure time, and generally, a delay of several tens of lines can be achieved.

Thus, by providing the first serializer 120a in the camera 100, the first deserializer 250a connected to the first serializer 120a in the processor device 200, the second serializer 260a in the processor device 200, and the second deserializer 320a in the monitor device 300, a technical effect of enabling long-distance data signal transmission is achieved.

Wherein the first clock signal, the second clock signal and the third clock signal are synchronized.

Then, the image sensor 110 captures a video image corresponding to the surrounding situation of the automobile and transmits an electrical signal corresponding to the video image to the first transceiver 120b. The first transceiver 120b transmits the electrical signal to a second transceiver 250b provided in the processor device 200.

Finally, the third transceiver 260b transmits the image signal to the fourth transceiver 320b. The fourth transceiver 320b transmits the image signal to the display 310. The display 310 directly displays a video image.

Thus, by providing the first transceiver 120b in the camera head 100, the second transceiver 250b connected to the first transceiver 120b in the processor apparatus 200, the third transceiver 260b in the processor apparatus 200, and the fourth transceiver 320b in the monitor apparatus 300, a technical effect of being able to transmit data signals is achieved.

The utility model discloses a camera monitored control system 10. The camera monitoring system 10 is provided with a synchronous clock processor 210. Wherein the synchronized clock processor 210 is connected with the camera 100 and the monitor device 300, respectively, and the synchronized clock processor 210 is configured to transmit a first clock signal to the camera 100, a second clock signal to the monitor device 300, and a third clock signal to the image signal processor 210, respectively. Wherein the first clock signal, the second clock signal and the third clock signal are synchronized. Since the image signal processor 210 is connected with the synchronous clock processor 220, the first clock signal transmitted to the camera head 100, the second clock signal transmitted to the monitor apparatus 300, and the third clock signal transmitted to the image signal processor 210 are synchronous clock signals. And since the first clock signal, the second clock signal, and the third clock signal are synchronous clock signals, the monitor apparatus 300 can synchronously display video images while the camera head 100 captures and scans the video images. That is, the camera monitoring system 10 provided in the technical solution of the present disclosure can achieve as low a delay as possible in the process from the video image acquisition to the video image display.

For ease of description, spatially relative terms such as "over 8230 \ 8230;,"' over 8230;, \8230; upper surface "," above ", etc. may be used herein to describe the spatial relationship of one device or feature to another device or feature as shown in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary terms "at 8230; \8230; 'above" may include both orientations "at 8230; \8230;' above 8230; 'at 8230;' below 8230;" above ". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the orientation words such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, and in the case of not making a contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be interpreted as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

The above description is only for the preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
