Description

[0001] The present invention relates to a device for connecting a mobile camera system, as well as to a corresponding method.

[0002] Modern vehicles often use camera systems to display various camera images on a vehicle-mounted display, such as a display and control unit. Both vehicle-mounted and mobile camera systems exist.

[0003] Previous methods often use vehicle-mounted camera systems, such as systems for monitoring the rear of the vehicle or the area around the vehicle, which employ permanently installed rear and front cameras. The camera images are digitally processed and displayed in real time, for example, on a display of a vehicle-mounted radio navigation system or in a display unit.

[0004] The cameras deliver real-time images of the vehicle's surroundings to the vehicle's built-in display. This allows the driver to have a clear view of the immediate environment. Such camera systems offer a variety of perspectives and views to provide optimal support for the driver in every traffic situation.

[0005] One or more cameras with 180° wide-angle lenses can be installed at the front, sides, and rear, thus extending the driver's field of vision by 90° to the left and right from the front or rearmost point of the vehicle. This allows the driver to see areas directly in front of, behind, or beside the vehicle that would otherwise be invisible. The system can therefore assist, for example, with difficult maneuvers such as coupling and maneuvering with a trailer, or when merging into situations with limited visibility off-road.

[0006] For example, DE 10 2011 106 838 A1 describes a method for displaying critical traffic situations in a vehicle, in which a camera can record the traffic situation and thus determine, for example, the distance of an approaching vehicle and thus the degree of danger to the own vehicle.

[0007] Currently, the use of external mobile cameras in vehicles is also increasing. The driver benefits from the fact that these cameras, due to their compact form and appropriate mounting options, can be attached to many locations inside or outside the vehicle, thus better meeting the driver's specific needs and preferences.

[0008] According to the current state of the art, it is possible to connect external mobile cameras to smartphones mounted on the driver's console. For example, DE 10 2013 106 212 A1 describes the integration of a wireless camera from a mobile device into a vehicle, in which the camera captures the image data and transmits it to a transceiver, which then forwards the image or video information to an integrated vehicle cabin display, where this information is displayed as images or videos.

[0009] Further cameras for or on motor vehicles are known from documents US 2013 / 0145279 A1, US 8825289 B2 and DE 10 2012 008 284 A1.

[0010] Furthermore, the company DNT offers a parking assistance system with smartphone connectivity. This information was published online on April 18, 2013, by the internet service heise.de under the title "iPhone Parking Assistance for Reversing Camera." The mobile camera system consists of a license plate holder with an integrated wide-angle camera. This camera can capture an area of ​​up to 105 degrees horizontally and 70 degrees vertically, with LEDs built into the license plate holder illuminating the area in the dark. The license plate holder contains a Wi-Fi module that connects to a smartphone mounted on the vehicle's center console next to the driver. An application is used to establish the Wi-Fi connection between the wide-angle camera and the smartphone. This allows the driver to use the system for parking or reversing in general.

[0011] Furthermore, the publication "BMW integrates GoPro camera control" by Kai Schmerer describes the integration of an external mobile camera with the vehicle's own information and operating system. The described setup enables wireless control of the camera. The camera can be mounted inside the vehicle or outside, for example, on the bumper, roof, or an exterior mirror. Via a menu displayed on the on-board monitor, the driver can not only determine the start and end of a recording but also set the recording mode. The options include video and still image recording, as well as short- or long-range photo bursts. To optimize image quality, special modes for different driving situations, such as night driving or cornering, can also be activated.Furthermore, the camera can be switched on and off via the control system, and the battery charge level, Wi-Fi signal strength, and available recording capacity are displayed on the screen. A smartphone is used to connect the camera; it is connected to the information and operating system and links to the mobile camera via Wi-Fi.

[0012] With current technology, it is possible to control an external mobile camera via a smartphone and / or a control system, with the driver or another person in the vehicle performing the controls. However, there are also applications where it is desirable to use information from the vehicle in addition to the person's input to control the camera or adjust the display of the camera images. This could include, for example, the vehicle's speed, the time of day or night, or characteristic features in the vehicle's surroundings, and the data transmission and control of the external mobile camera can be automated.

[0013] Starting from the prior art described above, the invention therefore aims to provide a device with which information from the vehicle can be integrated into the control of an external mobile camera.

[0014] In this regard, a vehicle-mounted display device for connecting a mobile camera system to a vehicle according to claim 1, a mobile device according to claim 6, and a method for connecting the mobile camera system according to claim 9 are provided. The dependent claims define further embodiments.

[0015] According to the invention, the vehicle-mounted display device comprises a display and an interface for connecting the vehicle-mounted display device to the mobile camera device. A "mobile camera device" is a device with a camera that can be movably mounted at any location inside or outside the vehicle. The mobile camera device can, in particular, be an external mobile camera, a smartphone with an integrated camera, or an external mobile camera connected to a smartphone.

[0016] The vehicle-mounted display device includes a processing unit for controlling an application program on the mobile camera device, wherein the processing unit is configured to send data to the application program via the interface and to receive image data and display it on the screen.

[0017] The interface connection allows many standard and widely used components to be advantageously connected to the mobile display device.

[0018] The vehicle-mounted display device is designed to process information provided by the vehicle and / or a driver and send it to the application program on the mobile camera device, and to control the mobile camera device depending on the information.

[0019] Therefore, the application program for controlling the mobile camera system resides on the mobile camera system itself, allowing it to be flexibly adapted to the diverse requirements of different camera manufacturers. This advantageously reduces the need for any or only minimal adjustments to the vehicle-mounted display unit.

[0020] In a preferred embodiment, the information provided by the vehicle can be about the vehicle's condition. This allows the vehicle condition information to be advantageously used not only for driver operation but also for controlling the external mobile camera, enabling more precise control of the camera and a more comprehensive and accurate display of the information from the external mobile camera on the vehicle's fixed display device.

[0021] According to the invention, the vehicle-mounted display device is configured to control the mobile camera device via the application program using controls on the display and control unit. This advantageously achieves that the application program on the mobile camera device is controlled via the controls of the vehicle-mounted display device, while the application program for controlling the external mobile camera is located on the mobile camera device itself, not on the vehicle-mounted display device. This allows for better integration of camera products from different manufacturers, each with its own application program, into the vehicle-mounted display device.

[0022] Furthermore, the vehicle-mounted display device can be configured to receive image data from the mobile camera system in real time via the application program and display it on the screen. This allows the driver to immediately see important or interesting events captured by the camera on the display and react to them if necessary.

[0023] In another embodiment, the vehicle-mounted display device can be configured to receive image data from the mobile camera system via the application program and process it within the framework of augmented reality. Augmented reality advantageously provides the driver with additional information that goes beyond the pure image content. The current image or video is supplemented with computer-generated additional information or virtual objects by means of overlay / superimposition. The term "augmented reality" is also used in this context for augmented reality.

[0024] Furthermore, the vehicle-mounted display device can also be configured to receive image data from the mobile camera device via the application program and process it as part of a traffic and safety analysis. This allows the driver to benefit from receiving additional information, besides the image content, that includes safety aspects of the surrounding traffic while driving.

[0025] According to the invention, a mobile device with a display and an interface for connecting the mobile device to the vehicle-mounted display device is further provided. In addition, the mobile device includes a processing unit, which is configured to receive information from the vehicle-mounted display device via the interface, to send image data to the vehicle-mounted display device, and to control a camera.

[0026] The mobile device is set up to receive information provided by the vehicle and / or a driver, and to control the external mobile camera using the application program depending on the information from the vehicle and / or the driver.

[0027] One advantage of this setup is that the application program for controlling the camera resides on the mobile device, allowing it to be flexibly adapted to the diverse requirements of different camera manufacturers. In particular, this means that little to no modification is necessary on the vehicle-mounted display unit.

[0028] The mobile unit can be configured to include the camera. This allows the driver to connect the mobile camera directly to the vehicle's fixed display. In this case, no additional mobile unit is required.

[0029] In another embodiment, the mobile device can include a second interface for communication with the mobile camera, where the mobile camera is now an external mobile camera. This allows the external mobile camera to be advantageously connected to the mobile device via a special interface with suitable properties. Such a second interface could, for example, be a wireless WLAN interface.

[0030] Furthermore, according to the invention, a method for connecting a mobile camera device to a vehicle is provided, which includes sending data from a vehicle-mounted display device via an interface to an application program on the mobile camera device for controlling the mobile camera device.

[0031] One advantage of this approach is that the application program processes the data and the vehicle-mounted display device does not need to be equipped to process the data.

[0032] Furthermore, the procedure includes processing the data in the application program and controlling the mobile camera device via the interface.

[0033] This step is advantageous because the mobile camera setup is carried out by the application program, thus easily taking into account the requirements of different camera manufacturers.

[0034] In addition, image data can be transferred from the mobile camera device to the application program on the mobile camera device.

[0035] Thus, the image captured by the camera can be processed on the mobile camera device and made available for forwarding to the vehicle-mounted display device.

[0036] The image data is then sent from the application program to the vehicle-mounted display device and displayed on a screen.

[0037] The method can advantageously send information from the vehicle-mounted display device to the application program on the mobile camera device for processing, in order to control the mobile camera device depending on the information from the vehicle-mounted display device.

[0038] The invention is explained in more detail below with reference to the accompanying drawings and exemplary embodiments. The drawings show: Fig. 1. A schematic representation of a vehicle-mounted display device for connecting a mobile camera system to a vehicle. Fig. 2 another embodiment of the vehicle-mounted display device, Fig. 3 another embodiment of the vehicle-mounted display device, Fig. 4 another embodiment of the vehicle-mounted display device, Fig. 5 another embodiment of the vehicle-mounted display device, Fig. 6. A flowchart illustrating a procedure for connecting a mobile camera device to a vehicle, and Fig. 7. A representation of the view from the mobile camera device for child observation

[0039] Fig. Figure 1 shows a representation of a vehicle-mounted display device 1, with which a mobile device 20 can be connected to a vehicle. The vehicle-mounted display device 1 includes a display 4, on which, for example, data from the vehicle's information system can be displayed. Furthermore, the vehicle-mounted display device 1 includes a processing unit 8, with which information from a driver via the controls 7 can be processed. In addition, the processing unit 8 can process information from the vehicle, which is available via various sensors. Such sensors include, for example, speed sensors, GPS receivers for determining the vehicle's current position, light sensors, or rain sensors. By processing the driver's information together with the vehicle's information, the driver's intentions can be better recognized and supported.

[0040] The processing unit 8 can include a memory 11 and a processor 14, wherein the processor 14 can, for example, execute programs located in the memory 11 to provide functionalities of the vehicle-mounted display device 1. Furthermore, the processing unit can send and / or receive data via an interface 17. The interface 17 can, for example, include a MirrorLink-based interface, a USB interface, a Bluetooth interface, a vehicle bus interface, an Ethernet interface, an RS232 interface, and / or a WLAN interface.

[0041] The vehicle-mounted display device 1 can be coupled to a mobile unit 20 via the interface 17. The mobile unit 20 comprises a display 5 for showing information from the mobile unit 20 and / or the vehicle-mounted display device 1. The mobile unit 20 further comprises a processing unit 9 with a processor 15 and a memory 12.

[0042] Furthermore, the mobile device 20 includes a camera 19 with which images or videos can be recorded. These images or videos can then be stored in the memory 12 on the processing device 9 and / or processed by the processor 15. The processing device 9 is configured to execute an application program ("app") located in the memory 12 on the processor 15. This application program processes information about an image or video recorded by the camera 19 and sends it to the vehicle-mounted display device 1 via the interface 17. The app also receives information from the vehicle-mounted display device 1 and analyzes this information. In addition, the mobile device 20 can be equipped with a second interface 18 for sending and receiving data.

[0043] Thus, the application program can control the mobile device 20, for example, by providing commands to adjust the camera 19 or by starting or stopping a video recording. The camera 19 receives the commands provided by the application program. To generate the commands for controlling the camera 19, the application program uses information provided by the driver and / or the vehicle's sensors via the vehicle's fixed display device 1. This information is sent via interface 17 to the processing device 9, which contains the application program.

[0044] Fig. Figure 2 shows a further embodiment of a vehicle-mounted display device 1, which is connected to a mobile camera device 2 via interface 17. The mobile camera device 2 comprises the mobile unit 20 and an external mobile camera 3, which is connected to the mobile unit 20 via interface 18.

[0045] The following describes functionalities that also apply in the same way to the devices in the Fig. 1 and Fig. 3 apply. All descriptions of the Fig. 2 can therefore be applied to the Fig. 1 and Fig. 3. The difference between the figures is that when controlling the camera 19, which is mounted internally in the mobile unit 20, the functions run internally within the mobile unit 20. If an external mobile camera 3 is connected to the mobile unit, the control functions run externally via a second interface 18.

[0046] In a preferred embodiment, the second interface 18 can be a WLAN interface. Other interface types, e.g., a MirrorLink-based interface, a USB interface, a Bluetooth interface, an Ethernet interface, an RS232 interface, or a vehicle bus interface, can also be implemented.

[0047] The external mobile camera 3 includes a lens system 6 with which images or videos can be recorded. These videos or videos can be processed by a processing unit 10 on the external mobile camera 3. For this purpose, a memory 13 can store the image data and / or a processor 16 can process the images. For example, the processing unit 10 can send the image data via interface 18 to the mobile unit 20, where it is received by the processing unit 9. The application program on the processing unit 9 can further process the image data and then, for example, send it via interface 17 to the vehicle-mounted display unit 1, where it can be displayed on the display 4. The image data can be displayed in real time, or it can be stored in the memory 12 of the mobile unit 20 or in the memory 11 of the vehicle-mounted display unit 1.

[0048] Furthermore, the application can control the external mobile camera 3, for example, to start or stop recording to record videos while driving or to pause the recording. The external mobile camera 3 can be mounted anywhere inside or outside the vehicle using suitable brackets. For example, the driver can attach the camera to the windshield to record events in front of the vehicle. Alternatively, the camera can be mounted outside the vehicle on or near the front bumper, allowing, for example, observation of the road while parking. Similarly, the camera can be mounted on the rear window or the rear bumper of the vehicle.

[0049] Such an arrangement is suitable, for example, for recording and storing videos while driving on roads or off-road, so-called off-road movies. These videos can then be viewed later via the display 4 of the vehicle-mounted display 1 or the display 5 of the mobile unit 20, or read out to another external device. The mobile external camera 3 can also be controlled via the application program, for example, to capture individual images. Furthermore, the application program on the processing unit 9 can be configured so that the recording and storage of the videos takes place in a virtual ring buffer, which is overwritten with current image data after a predetermined time.This allows special incidents during the journey, such as accidents, to be documented without having to store large amounts of video data for the entire duration of the journey.

[0050] If the vehicle itself is involved in an accident, the camera recording and the associated overwriting of the loopback buffer can be automatically stopped to prevent the deletion of important image data if the driver forgets or is unable to stop the camera. Stopping the recording and overwriting old data in the loopback buffer can be done automatically via an emergency mechanism in the vehicle that detects the accident and initiates specific emergency procedures.The emergency mechanism can be configured such that the vehicle-mounted display device 1 receives information about the occurrence of an accident situation via a CAN bus in the vehicle and forwards this information to the application program on the mobile device, so that, for example, the recording of the images is stopped immediately or the images continue to be recorded and the recording is only stopped when the duration of the recorded image content on the ring buffer before the accident falls below a certain time.

[0051] Furthermore, the operating parameters of the external mobile camera 3 can be configured or controlled via the vehicle-mounted display device 1, for example, the aperture or shutter speed can be changed without directly operating or touching the camera. This has the advantage that the driver can conveniently configure the external mobile camera 3 manually while driving without endangering road traffic. In the illustrated embodiment, the manual configuration is carried out via the application program of the processing unit 9 of the mobile device, which receives the configuration commands from the vehicle-mounted display device 1 via interface 17, processes them, and forwards them to the external mobile camera 3 via interface 18.

[0052] With the in Fig. In the arrangement shown in Figure 2, it is also possible to process image data from the external mobile camera 3 in real time and display it on the screen 4 of the vehicle-mounted display device 1. This allows the driver to see what the external mobile camera is recording at any given time and without delay. Depending on the camera's position inside or outside the vehicle, the driver can use the information to react and, for example, adjust their driving behavior. In one embodiment, the camera can be mounted inside the vehicle so that children inside can be monitored. In another embodiment, the camera can be mounted outside the vehicle in a horse trailer to monitor the horses' condition and detect potential problems during the journey in a timely manner.Furthermore, the mobile camera unit 2 can be configured so that the real-time image data from the external mobile camera 3 is only displayed on the display 4 when the driver activates a correspondingly configured control element 7. The image data can then be displayed for a specific, configurable duration, for example, 3 seconds, after which the display is deactivated. This allows the driver to briefly view the current real-time images as needed and then return to other content on the display 4. Additionally, the mobile camera unit 2 can be configured so that the display of the image content from the external mobile camera 3 is automatically activated when the vehicle is in a specific vehicle state or driving mode.For example, the camera can be mounted on the rear window or the rear bumper, and when reverse gear is engaged, the real-time display of images captured by the external mobile camera 3 is automatically shown on the display 4 of the vehicle's fixed display device 1. This display can continue, for example, until the vehicle reaches a certain speed limit, such as 15 km / h, at which point it is automatically switched off by the application. This automatic camera deactivation upon reaching a certain speed limit can be implemented for both forward and reverse driving.

[0053] Furthermore, certain parameters of the external mobile camera 3 can be automatically controlled via a brightness sensor integrated into the vehicle and connected to the vehicle's fixed display unit via a CAN bus. This allows, for example, the camera's aperture to be automatically controlled while driving, without the driver having to make any manual adjustments.

[0054] Furthermore, the mobile camera system 2 can be configured to function as a parking aid. For this purpose, the external mobile camera 3 can, for example, be mounted on the rear bumper in such a way that it can view the road markings and / or another vehicle behind the vehicle. The external mobile camera 3 can then be activated automatically, for example, when reverse gear is engaged.

[0055] In another embodiment, the external mobile camera 3 can be mounted on the vehicle in such a way that an obscured road situation, for example a street corner that is not visible to the driver, can be viewed via the camera. For this purpose, the mobile external camera 3 can, for example, be attached to an end area of ​​the front bumper using a suitable bracket.

[0056] In another embodiment, the mobile camera system can be used for augmented reality (AR) analysis. AR refers to the computer-aided enhancement of a user's perception of reality, providing information that goes beyond the user's perception. This information can engage all of the user's senses. Augmented reality is often understood, for example, as the visual representation of information, i.e., the supplementation of images or videos with computer-generated additional information or virtual objects by means of overlay and / or superimposition. For example, if the images from the external mobile camera 3 are transmitted to the display 4 in real time during navigation, navigation instructions can be projected onto the image, so that, for instance, turn-by-turn directions appear on the road.Thus, augmented reality analysis can support and refine the functions of the navigation system by providing additional information.

[0057] This additional information can be obtained via the application program on the mobile device 20, whereby the mobile device can be connected to the Internet and data used to calculate the additional information can be obtained from an external database on the Internet.

[0058] One example of augmented reality analysis in vehicles is the vehicle finder. The position of the parked vehicle is stored on the mobile device 20 via the application program. If the driver has moved away from the vehicle and has the mobile device with them, they can locate the vehicle using the vehicle finder. The mobile device 20 can then display the direction of the parked vehicle, the street name, and the vehicle's current distance from the vehicle on the display 5.

[0059] Furthermore, in one embodiment, the mobile camera device 2 can be used with the vehicle-mounted display device 1 to store the image content recorded by the camera during a trip or the Google Street View image content of the trip in a database that also includes image content from other trips. This allows a large number of image data sets from different trips to be stored.

[0060] In another embodiment, the mobile camera device 2 can also be used for traffic and safety analysis. For this purpose, the mobile camera device 2 can, for example, be used to observe the driver's face, and in particular their eyes, and, with a suitable application program, to detect, by comparing this with movement patterns, whether the driver is becoming tired and thus at risk of microsleep. This risk can be particularly increased during long journeys in the dark or under constant conditions and long stretches of straight road, because these conditions reduce the driver's attention and the monotony further increases the risk of falling asleep. If the mobile camera device detects that there is a risk of microsleep due to altered movement patterns of the face and / or eyes, the vehicle-mounted display device 1 can emit a signal tone to warn the driver.

[0061] Furthermore, the vehicle-mounted display device 1, together with the mobile camera device 2, can be used to monitor traffic in the vicinity of the vehicle. For example, the camera can determine the traffic density surrounding the vehicle and derive information such as the vehicle's likely arrival time at its destination.

[0062] During the journey, the mobile camera device 2 can also be used to make video-assisted telephone calls, with the external mobile camera 3 being used to record the driver or one or more other persons in the vehicle participating in the telephone call and to provide the video data as part of the telephone call.

[0063] Furthermore, photos and videos captured by the mobile camera device 2 can be made available via appropriate virtual platforms to provide users with the recorded images or videos. For this purpose, the photos or videos can be copied to the relevant platforms via an internet interface.

[0064] Furthermore, the mobile camera unit 2 can be used to improve the driver's visibility in the dark. Such a night vision assistant can be implemented, for example, by incorporating an infrared illuminator on the external mobile camera 3. This illuminator illuminates the surroundings, and an infrared sensor, which can be part of the external mobile camera 3, captures the illuminated image, providing the driver with better visibility. This night vision technology has the advantage of not dazzling oncoming traffic, as infrared light is invisible to the human eye. Additionally, the external mobile camera 3 can be configured to capture the infrared radiation emitted by objects as an image or video. This allows warmer objects, such as living beings, to stand out against their colder surroundings as bright objects.

[0065] Furthermore, the mobile camera device 2 can be configured to automatically recognize traffic signs and display them on the screen 4. The external mobile camera 3 can record the roadside and transmit the images to the application program. The application program can be equipped with an image processing program configured to analyze images for known patterns characteristic of traffic signs. The image processing program then determines the meaning of the traffic sign and provides the driver with this information via the screen 4.

[0066] In another embodiment, the mobile camera device 2 can be configured to detect when the moving vehicle deviates from its lane and thereby assumes the function of a lane keeping assistant, with this function being implemented in a corresponding part of the application program. The mobile camera device 2 determines the lane via the application program by having the mobile external camera 3 record the road and compare it with specific lane markings. If the vehicle deviates from its lane, the lane keeping assistant can display a warning signal on the screen 4 and / or warn the driver with an audible warning signal.

[0067] Fig. Figure 3 shows another embodiment of a vehicle-mounted display device 1, wherein in this case the external mobile camera 3 is directly connected to the vehicle-mounted display device via interface 17. Here, the application program for controlling the external mobile camera 3 is implemented in its processing unit 10. The advantage of this arrangement is that the mobile unit 20 is not required, and thus the entire arrangement is more compact compared to the overall arrangement consisting of the Fig. 2 is simplified. All functionalities apply to the overall arrangement of the Fig. 3 in the same way as in Fig. 1 and Fig. 2 described.

[0068] Fig. Figure 4 shows a schematic arrangement consisting of a modular information system (“MIB”) and a display and control unit (“ABT”) connected to a customer mobile radio device 22 via interface 17. The schematic representation shows that the MIB / ABT 21 controls the customer mobile radio device 22 using vehicle sensors and vehicle data 27, with the application program 25 on the customer mobile radio device 22 processing the data. The control 26 of the external mobile camera based on vehicle sensors and data can be performed directly from the MIB / ABT 21. The external mobile camera 3 can be connected to the customer mobile radio device 23 via the second interface 18. The batteries of the customer mobile radio device 23 can be powered via a charging cradle 24 and a USB power supply 30.

[0069] Fig. Figure 5 shows another embodiment of the Fig. The arrangement shown in Figure 4 is as follows. Here, the external mobile camera 3 comprises an operating system 32, which can be, for example, an Android operating system, and an interface connection 31. The interface connection 31 can be a MirrorLink interface connection, which allows the external mobile camera 3 to be connected to the MIB / ABT 21 via interface 17. The external mobile camera 3 is powered by a charging cradle 24 and a USB power supply 30. Alternatively, the customer's mobile phone 22 can be used instead of the external mobile camera 3 if it has an integrated camera.

[0070] Fig. Section 6 describes a method for connecting a mobile camera device to a vehicle. In a first step, S1, the data containing information provided by the driver and / or the vehicle are sent from the vehicle's fixed display device to the application program on the mobile camera device via an interface.

[0071] In a second step S2, the received data is processed in the application program located in the memory of the mobile camera unit's processing device. The advantage of this arrangement is that the processing of data generated by the vehicle's sensors and driver input via the controls on the vehicle's fixed display is handled by the application program on the mobile camera unit. If software adjustments are necessary, these can be made on the mobile camera unit; adjustments on the vehicle's fixed display or any other part of the vehicle are unnecessary.

[0072] In one embodiment, the mobile camera system can consist of a mobile unit and an external mobile camera. The processed data can be used to control the external mobile camera, which may be connected to the mobile unit via another interface. The application program can control the external mobile camera, with the control commands being provided by the vehicle's fixed display unit and / or vehicle sensors.

[0073] In a further step, S3, the image data from the mobile camera system is sent to the application program on the mobile camera system. There, the image data is processed and made available for further use. If the mobile camera system consists of the mobile unit and the external mobile camera, the external mobile camera can send the image data to the mobile unit, where it can be processed and made available for further use.

[0074] In step S4, the image data is sent from the application program on the mobile camera device to the vehicle-mounted display device via an interface.

[0075] In a further step S5, the image data is displayed on the vehicle's stationary display device. The image data can be displayed in real time or with a time delay. In another embodiment, the image data can be stored in memory. For this purpose, the application program can, for example, use the memory in the processing unit of the mobile unit or the memory in the processing unit of the external mobile camera. Storing the image data in the memory of the vehicle's stationary display device's processing unit is also possible. Either a linear memory or a virtual ring buffer can be used for storage.

[0076] Fig.Figure 7 shows an integrated representation of a viewing angle of the mobile camera device 2 for child observation.
