Description

[0001] The present invention relates to an optical assembly for a camera system for a vehicle. The present invention further relates to a camera system, a camera monitor system comprising the camera system, and a vehicle comprising the camera system. Furthermore, a method for aligning such an optical assembly and a method for analyzing and processing image data from at least one camera system are provided.

[0002] When driving a vehicle, it is particularly important to be able to perceive the vehicle's surroundings. Rearview mirrors, for example, can provide a view of the sides of the vehicle. However, some areas of vision remain obscured, such as blind spots. Furthermore, there are areas of vision, for example, in the immediate vicinity of the vehicle at the front, rear, or sides, which are not visible to the driver or even with rearview mirrors.

[0003] Furthermore, distant areas may appear very small and sometimes unclear to the driver when using rear-view devices. In particular, the behavior of other road users, whether in close proximity or at a distance, can lead to dangerous situations. Recognizing these situations can be impaired by the driver's cognitive abilities and / or experience, or by a lack of concentration. Generally, careful driving requires paying attention to other vehicles or obstacles positioned in front of, behind, to the side of, etc., the vehicle.

[0004] Therefore, various camera systems are used in vehicles to support drivers, for example, by providing supplementary rearview mirrors or by transmitting specific fields of vision. Due to the requirements for safe and anticipatory driving, both the near and far areas around a vehicle must be covered.

[0005] A system for monitoring the surroundings of a vehicle by recording the vehicle's surroundings using cameras mounted at the front, rear, left and right of the vehicle, and a system for detecting a blind spot were proposed.

[0006] WO 2023 / 006832 A1 relates to a camera monitor system for a motor vehicle, in particular in the form of a truck, preferably with a trailer, comprising: a camera designed to be mounted on a motor vehicle and having at least one field of view (FOV) and a controller, wherein the camera comprises a lens with a lens central axis and an imager, and wherein the imager has an imaging center aligned with the lens central axis and a pixel array divided into a first imager area and a second imager area, the first imager area having a first imager area center offset from the lens central axis.The first imager area is an active imager area defined by an array subset of activated pixels; the second imager area is an inactive imager area defined by an array subset of deactivated pixels; and the controller only receives image data from the activated pixels in the active imager area and not from the deactivated pixels in the inactive imager area.

[0007] US patent 10 666 908 B2 discloses a camera module containing a plurality of lenses mounted in different directions to form each image, an image sensor unit mounted to be moved into appropriate positions for each image formed by the plurality of lenses, a guide part that selectively moves the image sensor unit, and an image processor that processes an image signal input from the image sensor unit.

[0008] EP 1 263 213 A1 relates to a camera system comprising a first imaging lens and a second imaging lens with different image acquisition directions, a reflection element for changing the beam path of an image captured with an imaging lens such that the image formation directions of the first imaging lens and the second imaging lens are aligned in the same direction, an imaging device having imaging surfaces on which images captured with the first imaging lens and the second imaging lens are formed, a signal processing element for processing an image signal converted into an electrical signal by the imaging device, a display section for displaying the image signal undergoing signal processing by the signal processing element, and a selection element for selecting the image signal.which corresponds to one of the first imaging lenses and the second imaging lens in order to display it on the display section.

[0009] Common camera systems require multiple cameras, each equipped with a lens and an imager. The multiple cameras and their imagers result in a large bandwidth for reading the video streams from the respective imagers, allowing the target areas within the camera's field of view to be output, processed, and / or digitally analyzed at high resolution and frame rate.

[0010] If a vehicle occupant requires different viewing areas, such as the view from a Class I Intelligent Rear View Mirror (IRVM) and a reversing view according to R158, the hardware must be provided twice. This requires, for example, two separate cameras and therefore two camera mounts, two video cables, two heating cables, two video cable connectors, and / or two video deserializers on a single electronic control unit (ECU). Furthermore, the installation requires approximately twice the effort compared to installing a single camera system, significantly increasing costs. Additionally, a sensor resolution sufficient to provide both the Class I (and wide pan) and R158 viewing areas with adequate resolution is necessary.

[0011] Furthermore, each camera requires its own integrated SerDes circuit and cable to transmit image data from the camera to the control unit. However, since the viewing angle of a camera module used in the system to monitor the vehicle's surroundings differs from the viewing angle of a camera module used in the system to detect a blind spot, a camera module must be used that can ensure different viewing angles for each driver assistance system and / or camera monitor system.

[0012] Furthermore, there is the problem that it is not possible to provide high-resolution displays of a Class IV area on one display.

[0013] In view of the aforementioned and other disadvantages inherent in the current state of the art, the objective of this disclosure is to further develop the known camera system for vehicles in order to overcome at least some of these disadvantages. In particular, the objective is to provide a multifunctional camera system in order to reduce the number of camera systems mounted on a vehicle. Furthermore, the objective is to optimize the efficiency of the data stream and the limiting bandwidth of the mounted camera systems for reading the video streams, thereby saving transmission and processing capacity while simultaneously providing high resolution and frame rate. A further objective is to reduce the material, components, and costs of the camera systems required for mounting and assembling the system in a vehicle.

[0039] Combining two lenses with different fields of view in a single optical assembly of a vehicle's camera system offers numerous advantages in terms of efficiency and performance. For example, a short-range and a long-range camera can be combined within a single system. This allows certain elements of the camera system to be shared by the different lenses, particularly a common imager that can project images across the lenses' fields of view. Consequently, image data from all projecting lenses combined in the camera can be read and transmitted simultaneously. Unlike the previous two-camera setup with two imagers and two data cables, this approach requires only one camera system with two lenses and two fields of view, but only one imager and one data cable.Simultaneous image data readout optimizes the bandwidth constraints for reading, transmitting, processing, and analyzing the video stream. Target areas of the camera's field of view can be output quickly, with less processing power, in high resolution, and at a high frame rate. This increases the efficiency and performance of the data stream.

[0040] Generally, a person skilled in the art understands a near-field of view either as a field of view in the immediate vicinity of the vehicle, or alternatively as covering parts of the vehicle, whereas a far-field of view is understood either as a field of view focused on the surroundings of the vehicle, or alternatively as including areas at a greater distance from the vehicle. The terms near-field and far-field of view are used based on this general understanding of the person skilled in the art.

[0041] The subject matter of the present disclosure further leads to a compact design through the reduction of components, such as the use of a common lens holder, by combining two cameras in one camera system while simultaneously maintaining different fields of view and thus providing different functionalities depending on the different fields of view. It also leads to reduced costs and less time required for the assembly of the camera system and for mounting the camera system on a vehicle.

[0042] The UV adhesive enables cost-effective and, in particular, accurate assembly of the camera system. The camera system components, especially the lens tubes, can be aligned at the appropriate position on the lens holder while the UV adhesive is still uncured. Once aligned, the adhesive can be activated and / or cured by UV light to join the elements of the optical assembly and secure them in a desired position relative to each other, especially the first and second lens tubes relative to the common lens holder. Active, time-controlled activation of the adhesive is particularly possible. The alignment process of the elements can be carried out in parallel or sequentially.The adhesive can be activated and / or cured with UV light once one or both lens tubes are correctly positioned on the respective lens holder seat, thus completing the attachment between the lens holder and the respective lens tube(s).

[0043] Furthermore, the UV adhesive allows the lens holder to provide two seats designed to support the first and second lens tubes. This configuration enables the modular design of the claimed camera system. The lens holder can be combined with various tubes, particularly tubes of different lengths and shapes, and conversely, a single tube can be combined with different lens holders. In this way, the number of components required can be reduced, since, unlike a multitude of different complete components where various permutations of possible lens holders and lens tubes are combined, only a limited number of basic components need to be kept on hand.

[0044] Within this document, the term alignment refers to a step during the manufacture of the optical assembly, whereas the term adjustment or adaptation refers to a movement during the use of the optical assembly and / or the camera with the optical assembly.

[0045] The term “dynamic” refers to a change in the constitution and / or condition, whereby the change is related to a time factor, such as the driver's driving behavior.

[0046] The overlapping fields of view of the different lenses of the camera system, as well as the overlap of the first and second areas of the imager, provide numerous opportunities for processing and analyzing the image data. For example, the different fields of view can be combined and / or aligned to display a 360-degree view and / or a combined image to the driver.

[0047] Heating elements enhance the camera system's safety features. The heat they generate removes water and / or ice from the lenses. The ring shape of the heating elements ensures even heat distribution.

[0048] Changing the field of view of one or more lenses provides the possibility to adapt the field of view as well as the processing and analysis of the image data to the driver and / or the vehicle behavior, as well as to the traffic, the environment and / or driving situations.

[0049] Artificial intelligence and / or machine learning can improve the process of changing the field of view as well as analyzing and processing image data. In particular, pattern recognition can be used, for example, based on driving behavior or the movement patterns of objects / road users, or the detection of specific objects or situations, to enable predictive and safe driving. The use of artificial intelligence and / or machine learning is independent of the driver's concentration or cognitive abilities. Due to the efficiency and performance of the data stream of the camera system according to the invention, the artificial intelligence and / or machine learning can react faster and thus improve the vehicle's driving safety.

[0050] It can be assumed that each of the described features and / or embodiments of the disclosure can be used separately or in combination with other disclosed features and / or embodiments. The term "at least one" refers to one or more and can even be understood as "all".

[0060] Fig. Figure 2 illustrates a cross-section of the embodiment of the optical assembly 2 of the camera system 1 according to Fig. 1. The following description is made with reference to the Fig. 1 and Fig. 2.

[0061] The camera system 1 according to the illustrated embodiments of the Fig. 1 and Fig. The optical assembly 2 comprises the optical assembly 2 – with a lens holder 5 – and an imager 3, which are attached to each other. The lens holder 5 provides two seats designed to support a first lens tube 7 and a second lens tube 9. The first and second lens tubes 7, 9 are attached to the lens holder 5 with a UV adhesive. The UV adhesive is applied to the lens holder 5 and / or the lens tubes 7, 9 during the assembly of the optical assembly 2. The UV adhesive allows for active image alignment while the adhesive is in an uncured state, meaning that the elements of the optical assembly 2 and the camera system 1 can be precisely positioned relative to each other before attachment. This alignment is achieved by actively and precisely activating and / or curing the adhesive using light in the UV spectrum.This alignment can include the relative alignment between lenses 10, 12 and / or a mirror 14, as well as the alignment of these elements relative to the imager 3. The alignment of lenses 10, 12 can be performed in parallel or sequentially. Therefore, once one or both lens tubes 7, 9 are correctly positioned on their respective seats of the lens holder 5, the adhesive can be activated and / or cured with UV light, thus hardening / sealing the bond between the lens holder 5 and the lens tubes 7, 9.

[0062] A first end of the first and second lens tube 7, 9 is attached to the lens holder 5, wherein an opposite second end of the first and second lens tube 7, 9 is designed to carry the first and second lens 10, 12 respectively.

[0063] According to the embodiment of the Fig. 1 and Fig. In the first lens 10, the first lens is designed to capture a first field of view 20 for a near range, and the second lens 12 is designed to capture a second field of view 22 for a far range. The far range of the second field of view 22 is designed to capture a portion of the vehicle's surroundings at a distance greater than the near range of the first field of view 20, which is designed to capture at least a portion of the immediate vicinity of the vehicle. In various embodiments, the first and second fields of view 20 and 22 can encompass at least part of the area defined in ECE R159 MOIS, ECE R151 BSIS, ECE R158, ECE R46, the blind spot area according to ISO 17387, the mirror class II area, the mirror class IV area, and / or the mirror class V area, and / or the SVS area around the camera. The ECE standards refer to the corresponding UN regulation regarding direct vision.According to various embodiments, the first field of view 20 and the second field of view 22 overlap at least partially or do not overlap.

[0064] The first field of view 20 is projected by the first lens 12 onto a first area 24 of the imager 3, whereas the second field of view 22 is projected onto a second area 26 of the imager 3. The optical axis of the first lens 10 is essentially horizontal and perpendicular to the imager 3. The optical axis of the second lens 12 is inclined. According to various embodiments, the optical axis of the second lens 12 can be inclined towards the ground or towards a side or the rear of the vehicle or its trailer. The first field of view 10 is projected directly onto the first area 24 of the imager 3, whereas the second field of view 22 is projected onto the second area 26 of the imager 3 by means of a deflecting mirror 14. The ratio of the size of the first area 24 to the size of the second area 26 depends on the image resolution required for the first and second fields of view 20 and 22.The higher the required resolution, the larger the area on the imager 3 needs to be for the respective field of view. According to various embodiments, the size of the first and second areas 24, 26 can be changed by an adjustable deflecting mirror 14.

[0065] According to the embodiment of the Fig. 1 and Fig. 2. The first and second lenses 10, 12 are equipped with a heat source comprising a first and second heating element 100, 102, respectively. The heating elements 100, 102 are arranged in a ring and surround the first and second lenses 10, 12 to provide heat evenly to both lenses. Providing heat can be particularly helpful for removing ice, snow, or water from the lenses 10, 12.

[0066] According to various embodiments, the heating elements 100, 102 can at least partially provide the fastening between the lens tube 7, 9 and the lens 10, 12. Furthermore, the attachment of the lens 10, 12 to the lens tube 7, 9 can preferably be sealed.

[0067] According to the embodiment of the optical assembly 2 of the Fig. 1 and Fig. In 2, the lenses 10, 12 and the lens tubes 7, 9 are fixed relative to the lens holder 5. In other embodiments, at least one lens 10, 12 and / or one lens tube 7, 9 can be movable relative to each other and / or to the lens holder 5 even after activation of the UV adhesive, for example, by using a hinge. In yet another embodiment, the lens holder 5 can be movable relative to the imager 3 in order to change at least one field of view 20, 22 and / or at least one area 24, 26 of the imager 3.

[0068] The optical assembly 2 of a vehicle-mounted camera system 1 can change the field of view 20, 22 by rotating about an axis and / or changing its position on the vehicle.

[0069] The optical assembly 2 of the Fig. 1 and Fig. 2 can be part of a camera system 1 comprising multiple optical assemblies 2 and / or imagers 3. In such a camera system 1 with more than one optical assembly 2 and / or more than one imager 3, two or more optical assemblies 2 and / or imagers 3 can interact. In another embodiment, the image data from two or more imagers 3 of such a camera system 1 are at least partially read out, transmitted, displayed, analyzed, and / or processed together. The optical assembly 2 and / or the imager 3 of the Fig. 1 and Fig. 2 and / or the camera system 1 may further be part of a camera monitor system, wherein at least part of the recorded image data of at least one imager 3 is displayed on at least one monitor.

[0070] The optical assembly 2 and / or the camera system 1 according to the embodiment of the Fig. 1 and Fig. 2. These are designed to be mounted on a vehicle. In particular, this can be a vehicle in the form of a truck, and more specifically, a truck that has at least one trailer attached to it.

[0071] Fig. Figure 3 schematically represents an embodiment of a recording of the first and second fields of view 20, 22 of an optical assembly 2 according to the invention. On the left side of Fig. Figure 3 shows the first field of view 20 with a wide opening angle of approximately 168° × 148°. On the right side of Fig. Figure 3 shows the second field of view 22 with a narrow opening angle of approximately 63.54° × 44°. The potentially usable digital image data of the first and second fields of view 20, 22 are limited by the active imager zone 28. The active imager zone 28 defines the areas of the recorded first and second fields of view 20, 22 that are perceived by the imager 3 as an image sensor and thus correspond to the first and second areas 24, 26 of the imager 3. According to various embodiments, the active zone 28 is defined by the design of the imager 3, the software, and / or the calibration. Fig. Figure 3 shows, by way of example, the different areas of mirror class II, IV and V within the recorded fields of view 20, 22.

[0072] According to Fig. Figure 4 provides an embodiment of a method for analyzing and processing image data from at least one imager 3 and / or camera system 1. In a first step 500, the first and / or second field of view 20, 22 can be adapted to a defined target field of view, in particular according to the sensor data, the mounting position, the driver input, and / or the software feedback. The software feedback is to be understood as any signal that is output by software and / or a processor that processes and / or analyzes data, e.g., from the vehicle, the driver, or, in particular, image data from a camera system 1. In this step, the fields of view 20, 22 must be adapted according to the driver's safety requirements and personal needs, or depending on a driving situation, in order to take the current driving situation into account. The field of view depends, for example, on the main direction of travel.Therefore, the first step must be performed dynamically according to the changed driving situation and / or is calibrated after the camera system 1 has been mounted on the vehicle.

[0073] In a second step 502 of the procedure, the first and second readout areas 24 and 26 on the imager 3 must be defined. According to various embodiments, the size of the first and / or second readout area can be zero and / or non-zero. This step can be part of a calibration after the camera system 1 has been mounted on the vehicle. In another embodiment, this step is performed analogously to the first step 500, according to the driving situation. Depending on the installation side of the camera system 1, the first and / or second readout area ("active sensor area") is determined, for example, by software, so that the area covered by the camera system 1, extending away from the vehicle, is captured, and no additional areas of the vehicle that are not of interest are captured.

[0074] The second step, 502, ensures that only the required portion of the first and second areas 24 and 26 of the imager 3 is read. Optimizing the data stream and the image data processing time ensures that the driver's needs and the driving situation are met.

[0075] In a third step (504), the image data from the first and second readout areas are read out and transferred to an electronic control unit. The control unit can be part of a camera monitor system or part of the vehicle.

[0076] In a fourth step 506, the image data read out from the first and second readout areas are processed. According to various embodiments, the processing step 506 is performed at least partially in the electronic control unit. In other embodiments, a further processing unit is necessary to process the readout image data. If a field of view 20, 22 is projected onto the imager 3 via a mirror and / or the field of view is mirrored by another optical or digital effect, the processing step includes reflecting the readout mirrored image data back onto the imager. Furthermore, the processing step includes cropping, distorting, and / or colorizing at least a portion of the readout image data.Furthermore, step 506, the fourth step, can include removing and / or correcting certain parts of the read image data, such as removing recorded objects, image defects, or unimportant image sections, and / or correcting exposure errors, color errors, or reflections, and / or resizing at least part of the image to be displayed. Additionally, step 506 can include adding image data, such as highlighting certain objects or areas of the image to be displayed, or adding new image data in the form of signals, such as a warning symbol.

[0077] In a fifth step (508), the processed image data and / or extracted raw image data are analyzed to generate further information for the driver and / or a vehicle assistance system. In particular, the generated information is used for predictive and resource-saving driving. It can also be used for autonomous driving.

[0078] Step 508 of the analysis is performed using software, in particular software based on artificial intelligence and / or machine learning. The software can be designed to detect objects and / or patterns (e.g., of the driving situation, the environment, driving behavior, the behavior of other road users) and, in particular, to recognize potential hazards. According to various embodiments, the software is designed to recognize the different fields of view of the first and second readout areas, in particular to distinguish between the near and far fields of view. The assistance system, equipped with information from analysis step 508, can include lane / traffic sign recognition, brake assist, autonomous driving, distance assist, and / or collision warning.The assistance systems containing information can change depending on whether image data from the near or far field of view is being analyzed.

[0079] In particular, the information from analysis step 508 can be sent to the control unit and / or processing unit of step 506 to add, remove, and / or modify image data to be displayed. For example, warnings can be issued in the form of visual and / or audible signals. Visual output can take the form of highlighting a detected object of interest and / or a vehicle part of interest, or any other area of ​​the image to be displayed. Visual output can also take the form of a letter, text, symbol, and / or image, with the processed image being overlaid by these visual outputs.

[0080] In a further embodiment, step 508 of the analysis process comprises detecting and / or locating at least one part of the vehicle, in particular an attachment, such as a trailer and / or the end of the trailer, in order to send a warning and / or information to the driver by means of a visual and / or acoustic signal. This function allows the driver to track the location of the attachment and / or the trailer. Especially in the case of trucks with at least one large trailer, it is important for the driver to know the position of the trailer and to predict its behavior while driving. This is important in reversing or parking situations where the driver might misjudge their driving behavior in relation to the trailer's movement.This step 508 can, for example, prevent the angle between the trailer and the truck from being too narrow or the driver's driving behavior from leading to a collision of the trailer with another object.

[0081] In yet another embodiment, the image data is used for a launch assist system. This system supports the driver during startup by issuing warnings and / or influencing and / or adjusting the vehicle's behavior. The launch assist can be used in stop-and-go situations, for example, near intersections, traffic lights, and / or traffic jams, to prevent obstructing traffic by keeping the vehicle stationary longer than necessary. The launch assist can also warn the driver and / or influence the vehicle's behavior if vulnerable road users, such as cyclists and / or pedestrians (e.g., children playing), are detected.

[0082] In a sixth step 510, the processed image data from the first and / or second readout area are displayed, at least partially, on at least one monitor. The image data from the first and / or second readout area can be displayed, at least partially, together in a combined image or individually. In embodiments with an at least partially combined image of the first and / or second image data, at least part of a panoramic view of the vehicle and / or trailer can be displayed.

[0083] According to various embodiments, the camera system 1 and / or the electrical control unit can output at least some of the results of steps 506 and 508 of processing and / or analyzing the first and / or second readout area as a CAN signal. In another embodiment, the results are output via a monitor of a camera monitor system and / or via a device for outputting an acoustic signal, such as a loudspeaker.

[0084] With the help of Fig. Sections 5 to 6e describe an application of the optical assembly 2'. The Fig. The elements shown in Figures 5 to 6c, which correspond to the elements of the camera system 1 and the optical assembly 2 respectively, have the same reference numerals, but with an apostrophe. The optical assembly 2' contains a camera system 1' and is used to simultaneously provide a digital intelligent rearview mirror (IRVM) that displays the Class I field of view represented by the second field of view 22', and a reversing view according to R158, which is represented by the first field of view 20' with a sensor. The claimed optical assembly 2' particularly allows a camera system 1' to be provided that comprises a single camera with a single sensor and linear lenses capable of providing the second (Class I) field of view 22' and the first (R158) field of view 20' at sufficient resolution.

[0085] To achieve this, the single camera 1', which has two lenses in lens tubes 7', 9', is optionally connected via an ECU 30' to an internal rearview display that provides the correct Class I and R158 field of view 20', 22'. The dual-lens configuration allows the projection of the respective field of view 20', 22' onto two separate sensor areas 24', 26' on a single sensor. The views for the two fields of view 20', 22' can then be read out. Thus, it is possible to generate both views with just one camera system.

[0086] To provide the different field-of-view areas 20', 22', the camera system 1' is installed on a vehicle 32' such that the first lens and the second lens have an optical axis spanning a plane perpendicular to a ground surface of the vehicle 32' and / or a horizontal plane. The optical axis of the lenses is inclined at different angles relative to a horizontal direction extending parallel to the ground surface.

[0087] Reading out the individual sensor of the camera system is in Fig. Figure 6A shows two areas, 24' and 26', of an active imager area of ​​the sensor. The first area, 24', corresponds to a Class I field of view of 22', whereas the second area, 26', corresponds to an R158 field of view of 20'.

[0088] The use of different 24' and 26' sections of the single sensor allows for a readout rate of 60 fps, providing a high frame rate and high resolution for the display. Furthermore, at this frame rate, high vertical resolution (40° total) could be provided for Class I, while limited horizontal resolution would be possible. This allows for optimal sensor activation for both sections, i.e., for Class I and R158 views.

[0089] If more panning in the horizontal direction is required, the active sensor area could be adjusted according to the required readout of the intended HFoV (Horizontal Field of View) of, for example, 40°, and a range of up to 64° HFoV could be provided.

[0090] If a high-resolution panoramic view, i.e., up to 64° HFoV, had to be displayed on the screen, the frame rate could be reduced, thereby increasing and reading the active imager area.

[0091] The Fig. 6b to 6e represent different display options for the read data.

[0092] In Fig. 6b shows a display option 202b' where only the Class I field of view 22' is displayed. In particular, additional degrees could be provided around the minimum required FoV according to ECE-R46 for Class I.

[0093] In the Fig. Sections 6c to 6e show various options for simultaneously displaying the Class I field of vision (22') and the reversing field of vision (20') according to R158. Optionally, additional grades around Class I and R158 could be provided.

[0094] In Fig. 6c displays the reversing field of vision 20' as a picture-in-picture of the Class I field of vision 22'.

[0095] In Fig. 6d the reversing field of vision 20' is displayed as picture-by-picture with the Class I field of vision 22'.

[0096] In Fig. 6e the reversing field of vision 20' is displayed as a complete image, which still displays the Class I field of vision 22' in the form of a picture-in-picture.

[0097] To display a high-resolution image of the field of view, for example of a Class IV area, it is proposed that the camera system using the claimed optical assembly employ a [missing information] Fig. 7 and Fig. The technique described in section 8 is used.

[0098] Fig. Figure 7 shows the projected first field of view 20" and a second field of view formed by a first second field of view 22" and a second second field of view 23a", captured by a camera system according to a further embodiment of the invention. This embodiment allows display at a first frame rate of 30 fps together with the corresponding display shown to a user. The in Fig. 7 and Fig. The 8 elements shown, which correspond to the elements of the previously described embodiments, have the same reference numerals, but with two apostrophes.

[0099] The first field of view 22'' represents a Class V view. To generate the Class II field of view, the first second field of view 22'' is defined in step 502 and read out in step 504. To generate the Class IV field of view, the predominant part of the sensor element, in the form of the second second field of view 23a'' and an active imager zone 28a'', is defined in step 502 and read out in step 504. This results in the Class II field of view area 22'' being read out, along with almost all horizontal extensions for the Class IV field of view 23a'', including the second second field of view 23a'', in step 504. The data is then processed in step 506, allowing for a high-resolution display in step 510.

[0100] Fig. Figure 8 represents the projected first (Class V) field of view 20'' and a second field of view formed by a first second field of view 22'' and a second second field of view 23b'', captured by a camera system according to the invention. The camera system is similar to the one shown in Fig. 7 used, but allows a display in step 510 with a second frame rate of 50 fps along with the corresponding display shown to a user. To generate the Class II field of view, the first second field of view of 22'' is defined in step 502 and read out in step 504. To generate the Class IV field of view, a reduced portion of the sensor element is used compared to Fig. 7 in the form of the second field of view 23b'' and an active imager zone 28b'' is defined in step 502 and read out in step 504. This results in a readout of the Class II field of view 22'' together with a plurality of horizontal extensions for the Class IV field of view 23b' in step 504, which allows a high-resolution display in step 510, whereas in comparison to the one in Fig. In the configuration shown in 7, at least one further area 29'' outside the active imager area 28b'' of the sensor element is read from the wide field of view and combined in step 506 to display the correct part of Fig. 8. This will generate the display shown. In this way, it will be possible in step 510 to display the important parts of the Class IV view with an increased frame rate and high resolution.

[0101] As described above, although the embodiments are described by the limited embodiments and the drawings, various modifications and changes can be made by a person skilled in the art, starting from the above description. For example, suitable results can also be obtained if the described techniques are carried out in a different sequence than in the described procedure and / or components of the described system(s), structure, device, circuit, etc., are combined or combined in a different form than in the described procedure, or are replaced or substituted by other components or equivalents.
