Detailed Description

For a better understanding of the present disclosure, reference is made to the following detailed description taken in conjunction with the accompanying drawings.

Note that examples to be presented next are only specific examples, and are not to be construed as limiting the embodiments of the present disclosure necessarily to the specific shapes, hardware, connections, operations, numerical values, conditions, data, orders, and so on shown and described. Those skilled in the art can, upon reading this specification, utilize the concepts of the present disclosure to construct additional embodiments not described in the specification.

Terms used in the present disclosure are those general terms which are currently widely used in the art in consideration of functions related to the present disclosure, but they may be changed according to the intention of a person of ordinary skill in the art, precedent, or new technology in the art. Also, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present disclosure. Therefore, the terms used in the specification should not be construed as simple names but based on the meanings of the terms and the overall description of the present disclosure.

Flowcharts are used in this disclosure to illustrate the operations performed by systems according to embodiments of the present application. It should be understood that the preceding or following operations are not necessarily performed in the exact order in which they are performed. Rather, the various steps may be processed in reverse order or simultaneously, as desired. Meanwhile, other operations may be added to or removed from these processes.

As described above, in vehicles (e.g., advanced technology assisted driving motor vehicles), many camera systems are used, such as rear view cameras, panoramic cameras, and the like. Also, these camera systems are connected to an analysis processor for the purpose of Advanced Driving Assistance Systems (ADAS) to process image data obtained from the cameras in these camera systems by the processor. For example, the processor may be an Electronic Control Unit (ECU).

Fig. 1 shows a schematic diagram of an exemplary vehicle and camera system 100.

Referring to fig. 1, the camera system may include a plurality of cameras 101-106, the cameras 101-106 being distributed at suitable locations of the vehicle for different purposes. As shown in fig. 1, a front camera 101 may be mounted on a front side (e.g., a front bumper) of a vehicle for capturing image data of a front of the vehicle. A rear camera 102 (e.g., an HD camera) may be mounted on a rear side of the vehicle (e.g., a rear bumper) for capturing image data of the rear of the vehicle. Side cameras (e.g., left camera 103, right camera 104) may be respectively installed at left and right sides of the vehicle for capturing image data of the left and right sides of the vehicle. A driving camera (also referred to as an interior camera) may be installed in the cab for detecting image data of the interior of the vehicle. For example, the driving camera 105 may capture image data of the driver, and the driving camera 106 may capture image data of the passenger.

The image data from each camera may be transmitted to the processor 107 via cables routed within the vehicle (shown in FIG. 1 as line segments connected between the cameras 101-106 and the processor 107) and additional connectors (e.g., low cost connectors). For example, the front camera 101 may transmit image data from the front camera 101 to the processor 107 via a twisted pair cable (e.g., a lightweight unshielded twisted pair cable). These cables may for example have compensation properties (e.g. excellent cable compensation properties (up to e.g. 30 meters)). Via these cables, for example, freeze frame detection and video/cable diagnostics (e.g., freeze frame detection and extensive video/cable diagnostics) and sideband communications (e.g., bidirectional sideband communications) can be implemented.

The processor 107, which is implemented as an Electronic Control Unit (ECU) in the example shown in fig. 1, may process image data of the plurality of cameras 101 to 106 to perform display control so that the driver observes desired image data.

The camera system shown in fig. 1 is described below in conjunction with fig. 2 and 3.

Fig. 2 shows a schematic diagram of an exemplary camera system 200.

Referring to fig. 2, the camera system 200 may include a front camera 201, a rear camera 202, a left camera 203, a right camera 204, a driving camera 205, a processor 207, a main monitor 208, a left monitor 209, and a right monitor 210.

The front camera 201, the rear camera 202, the left camera 203, the right camera 204, the driving camera 205 may be similar to the front camera 101, the rear camera 102, the left camera 103, the right camera 104, the driving cameras 105-106 described with reference to fig. 1, and the processor 207 may be similar to the processor 107 described with reference to fig. 1, and will not be described herein. The number and types of cameras and/or monitors shown in fig. 2 are merely exemplary and may be changed, e.g., increased or decreased, as desired.

Referring to fig. 2, a front camera 201, a rear camera 202, a left camera 203, a right camera 204, a driving camera 205 are connected to a processor 207. The processor 207 may process, e.g., select, zoom, rotate, etc., the image data from the cameras 201-205. The main monitor 208, the left monitor 209, and the right monitor 210 are connected to the processor 207, and finally display image data processed by the processor 207 from the processor 207.

Fig. 3 shows a schematic diagram of an exemplary monitor 300.

The monitor 300 shown in fig. 3 may be used to implement any one or more of the main monitor 208, the left monitor 209, and the right monitor 210 described with reference to fig. 2.

Referring to fig. 3, the monitor 300 may include a Display Driver (also referred to as a Display Driver IC (DDI)) and a Display panel 320. The display driver 310 includes a display input unit 302, a timing generator module 304, a display control unit 306, an analog control unit 308, and an analog unit 309.

The display input unit 302 may be connected to a processor (e.g., the aforementioned processor 207) to receive image data from the processor. Here, the image data may be signals in LVDS, MIPI, DSI, or the like, or the image data may be embodied as LVDS signals, MIPI signals, DSI signals, or the like for transmission, a corresponding interface may be provided for transmission of the image data, and the image data (e.g., picture data or video data) itself may select a corresponding format, such as RAW, RGB, YUV, or the like, as needed, and may be further encoded in, for example, h.264, h.265, MPEG, or the like. In some example application scenarios, during the transmission, the image data may be a signal in an LVDS format, and the transmission of the LVDS signal may be performed through an LVDS interface provided between the display input unit 302 and the processor, so as to achieve the transmission of the image data. Likewise, a suitable interface may be provided between the camera and the processor or other subject for transferring image data to effect the transfer of image data.

In the following, a unit/module with a prefix of "LVDS" may be understood as being suitable for signals of the LVDS type. Of course, "LVDS" may also be replaced with "MIPI" or "DSI" or the like and applied to MIPI or DSI or the like type signals.

The display input unit 302 may also convert image data into dedicated display signals, such as RGB digital data. In some example application scenarios, during transmission, the image data may be a signal in an LVDS format, and the LVDS signal may include a color component (e.g., RGB) signal for the pixel point. The display input unit 302 may convert the LVDS signal (which is an analog signal) into a pixel signal (which is a digital signal) corresponding to the display panel corresponding to the RGB digital data, in which case the display input unit 302 is referred to as an LVDS input unit.

The timing generator module 304 may perform black display before image data is input and switch to the dedicated display signal when image data synchronization is detected. In some exemplary application scenarios, during transmission, the image data may be signals in LVDS format, and when LVDS synchronization is detected, the timing generator module 304 switches to LVDS-converted pixel signals to display the pixel signals on the display panel in a row-by-row refreshing manner according to timing control.

The display control unit 306 may enhance (e.g., gamma convert, make it darker or lighter) the display data and match the display panel.

The analog control unit 308 may generate a display panel driving control signal.

The analog unit 309 may convert the pixel signals into voltage signals for driving the display panel to display.

Accordingly, the display driver 310 may convert the input image data into a corresponding driving signal for driving the display panel and output the same.

The display panel 320 may be an LCD display panel, an organic light emitting diode, a projection device (e.g., a heads-up display), or other display device.

The inventors of the present disclosure have realized that in the embodiment referring to fig. 1 to 3, a processor (e.g., an ECU) needs to process image data from all cameras and send the processed image data to a display driver for display. In this case, the data throughput associated with the processor is very high. For example, 1 full high definition (1920 x 1080) image data rate is 1.9Gbps, and 6 full high definition cameras will be up to 11.9Gbps. High data throughput increases the efficiency of the processor in processing image data, resulting in display delays of the image data of the camera. In addition, in the processor, the ADAS is required to have both the zoom-out function and the target detection and tracking function, which results in more complex processing resources, and thus more complex and costly processor.

At least one embodiment of the present disclosure provides a display driver, an operation method of the display driver, and a monitor, which can reduce processing of image data by a processor (e.g., an ECU), reduce display delay of the image data, and improve display speed of the image data.

Fig. 4A illustrates a schematic diagram of a display driver 400 according to at least one embodiment of the present disclosure.

Referring to fig. 4A, the display driver 400 includes an image pickup device input unit 410 and a display driving unit 420. For example, these units may be implemented by digital circuits, analog circuits, or any combination thereof, for example, by a combination of a processing circuit and a storage medium.

The image capture device input unit 410 is configured to be directly connected to the image capture device via a transmission medium in the vehicle and configured to receive first image data from the image capture device (also referred to as image data captured by the image capture device).

The transmission medium in the vehicle (hereinafter simply referred to as transmission medium) described herein may refer to a transmission medium that runs through or is distributed in the vehicle, and thus does not depend on the monitor, the image capture device itself, for example, provided outside of the monitor, the image capture device, for example. Therefore, the transmission medium according to at least one embodiment of the present disclosure is distinguished, for example, from a transmission medium between a camera capture component inside a camera itself integrated with a display screen and the display screen (referred to as a transmission medium in the camera), and from a transmission medium between a camera inside a vehicle-mounted monitor itself integrated with a camera and a display screen (referred to as a transmission medium in the monitor), and the like.

In some embodiments, the transmission medium in the vehicle may include a wired connection or a wireless connection, such as an electrical cable (e.g., the electrical cable described with reference to fig. 1), an optical cable, or air (i.e., wirelessly), among others. Thus, the transmission medium described herein may be an electrical cable, optical cable, air, or the like, running through or distributed throughout a vehicle. In some example application scenarios, the image capture device input unit 410 may be configured to be directly connected to the image capture device via air, which may be achieved by way of, for example, radio waves, e.g., a radio wave transmitter may be provided at the image capture device and a radio wave transmitter receiver may be provided at the image capture device input unit 410. In other example application scenarios, the image capture device input unit 410 may be configured to be directly connected to the image capture device via a cable (e.g., similar to the cable described with reference to fig. 1), e.g., one end of the cable may be connected to the image capture device and the other end of the cable may be connected to the image capture device input unit 410.

It should be noted that, unless otherwise stated, the connection in this document may not be limited to a connection via a transmission medium in a vehicle, but may be a connection via another connection means. In addition, unless otherwise indicated, a connection herein may be a direct connection (i.e., "direct") or an indirect connection.

In some embodiments, the image acquisition device may include a camera (e.g., the camera described with reference to fig. 1 or 3) or any other device capable of acquiring image data.

In some embodiments, during the transmission process, the first image data may be signals in LVDS, MIPI, DSI, or the like format. For example, the image capturing device may convert captured image data into a signal in an LVDS format for transmission via a processor inside thereof, that is, the first image data is embodied as an LVDS signal, and is output to the outside of the image capturing device through an LVDS interface (referred to as an LVDS output unit) for outputting the LVDS signal, and the LVDS signal is output to the image capturing device input unit 410 via a transmission medium. In some example application scenarios, the image capture device input unit 410 may be an LVDS input unit corresponding to an LVDS output interface of the image capture device, and configured to receive an LVDS signal from the image capture device as the first image data.

The display driving unit 420 is configured to be connected to the display panel, and is configured to receive the first image data from the image pickup device input unit 410 and drive the display panel to display using the first image data. As shown in fig. 4A, the display panel may be the display panel 320 described with reference to fig. 3.

As such, a display driver according to at least one embodiment of the present disclosure may be directly connected to an image capture device and drive image data output from the image capture device for display, avoiding display delays caused by a processor (e.g., an ECU) needing to process image data from all cameras before sending the processed image data to the display driver for display.

Other examples of display drivers according to at least one embodiment of the present disclosure are described below.

Fig. 4B shows a schematic diagram based on another example of the display driver 400 shown in fig. 4A. It is to be understood that the display driver shown in fig. 4B is merely exemplary, embodiments of the present disclosure are not limited thereto, and other alternative units may be envisaged to implement the corresponding functions, additional units may be included, some or all of the units may be combined, or a single unit may be divided into a plurality of sub-units. For example, the units or modules shown in fig. 4B may be implemented by digital circuits, analog circuits, or any combination thereof, for example, by a combination of a processing circuit and a storage medium.

In some embodiments, referring to fig. 4B, the display driver 400 according to at least one embodiment of the present disclosure may further include a through output unit 430. The transit output unit 430 may be configured to be connected to the processor and the image capture device input unit 410, and may be configured to obtain the first image data from the image capture device input unit 410 and then transmit (transit) the first image data to the processor. The processor here may be, for example, the processor described with reference to fig. 1 to 3.

In some example application scenarios, when the first image data is embodied as an LVDS signal, the transit output unit 430 may be an LVDS transit output unit and configured to obtain the LVDS signal from the LVDS input unit 410 and send the LVDS signal to the processor. As such, a display driver in accordance with at least one embodiment of the present disclosure may transmit image data acquired from an image acquisition device to a processor to facilitate further processing of the image data by the processor (e.g., pattern recognition, etc.). Of course, the embodiments are not limited thereto. In some embodiments, instead of or as an additional aspect of the transit output unit 430 described above, the first image data may be transmitted to the processor via a transmission medium-based connection between the image capture device and the processor, thereby transmitting the first image data to the processor.

In some embodiments, with continued reference to fig. 4B, a display driver 400 according to at least one embodiment of the present disclosure may further include a display input unit 440. The display input unit 440 may be configured to be connected to the processor and may be configured to receive second image data (also referred to as processor image data) from the processor and to transmit the second image data to the display driving unit 420, wherein the display driving unit 420 is further configured to receive the second image data from the display input unit 440 and to drive the display panel to display using the second image data. The second image data here may be image data obtained by subjecting image data received (from a certain image capturing apparatus), for example, to image data processing by a processor or image data not processed by the processor.

In some example application scenarios, when the first image data is embodied as an LVDS signal, the display input unit 440 may be an LVDS display input unit, and may be configured to receive the LVDS signal from the processor as the second image data and transmit the LVDS signal as the second image data to the display driving unit 420, wherein the display driving unit 420 is further configured to receive the LVDS signal as the second image data from the display input unit 440 and drive the display panel to display using the LVDS as the second image data. As such, a display driver in accordance with at least one embodiment of the present disclosure may receive image data from a processor (e.g., processor-processed image data) for display.

In some embodiments, with continued reference to fig. 4B, the display driving unit 420 may further include a data processing subunit 450 and a data driving subunit 460. The data processing subunit 450 may be configured to perform image data processing on the first image data, perform image data processing on the second image data, or perform image data processing on the first image data and the second image data to generate image processing data by the image data processing. For example, in ADAS, image data processing may include reduction, object detection and tracking, and the like. The data driving subunit 460 may be configured to drive the display panel to display the image processing data. As such, a display driver according to at least one embodiment of the present disclosure may perform, for example, image data processing that would otherwise be performed by a processor, i.e., transfer the image data processing performed by the processor into the display driver, reducing the processing resources of the processor, thereby reducing the complexity and cost of the processor. Of course, the embodiments are not limited thereto, and in some embodiments, the data processing sub-unit 450 may be omitted or no image data processing may be performed.

In some embodiments, the data processing subunit 450 may be configured to receive a control signal from the processor to decide whether to perform image data processing. Thus, the display driver according to at least one embodiment of the present disclosure can implement on and off control of the image data processing function, and improve the flexibility of use of the display driver.

In some embodiments, with continued reference to fig. 4B, the data processing sub-unit 450 may include a Scaling (Scaling) unit 452 or an Overlay (Overlay) unit 454.

The scaling unit 452 may be configured to be connected to the image pickup device input unit 410, for example, and may be configured to receive the first image data from the image pickup device input unit 410 and scale the first image data to generate image scaling data as the image processing data. For example, scaling may be used to change the resolution, display window size, etc. of an image corresponding to the first image data. As such, a display driver in accordance with at least one embodiment of the present disclosure may facilitate a scaled display of the first image data, for example to adapt to the size of the display panel.

In addition, the superimposing unit 454 may be configured to be connected to the scaling unit 452 and the display input unit 440, for example, and may be configured to superimpose the image scaling data and the second image data to generate the image superimposed data as the image processing data or to use the second image data to generate the image processing data. For example, the superimposition may be used to superimpose an image corresponding to the superimposed image scaling data and an image corresponding to the second image data, or to superimpose a layer in which an image corresponding to the superimposed image scaling data is present and a layer in which an image corresponding to the second image data is present. As such, a display driver in accordance with at least one embodiment of the present disclosure may overlay/fuse the scaled first image data with the second image data from the processor, i.e., move the overlay function from the processor to the display driver.

In some embodiments, the scaling unit 452 and the superimposing unit 454 may not perform the respective functions or be omitted. For example, the superimposing unit 454 may be configured to be connected to the image-pickup-device input unit 410 and the display input unit 440, for example, and may be configured to superimpose the first image data and the second image data to generate image superimposed data as the image processing data.

In some additional aspects, the superimposing may place the image corresponding to the second image data or a layer on which the image corresponding to the second image data is placed on top. For example, the first image data is an image of a scene (e.g., an image of a left parking space captured by a left camera while parking in a side position), and the second image data, as processed by the processor, may be an identification of an object of interest in the image of the scene (e.g., an identification of an obstacle of the image of the scene, such as displayed in outline, as implemented via pattern recognition techniques), such that placing the identification on top may enhance, for example, the viewing and recognition of the image of the scene by the driver. Of course, embodiments are not so limited, and in some embodiments, which image or layer on which the image is placed may be set by the processor or software.

In some embodiments, with continued reference to fig. 4B, the data driving subunit 460 may include a timing generator module 462, a display control unit 464, an analog control unit 466, and an analog unit 468. The timing generator module 462, the display control unit 464, the analog control unit 466, and the analog unit 468 may be the same as or similar to the timing generator module 304, the display control unit 306, the analog control unit 308, and the analog unit 309 described with reference to fig. 2, respectively, and are not described herein again.

In some embodiments, the display panel 320 may be a Liquid Crystal (LCD) display panel, a Light Emitting Diode (LED) display panel, a heads-up display device, or any display device capable of displaying image data.

In some embodiments, for example, the cable may be a lightweight unshielded twisted pair cable or other suitable cable. For example, the cable may be any cable such as described with reference to fig. 1.

Corresponding to a display driver according to at least one embodiment of the present disclosure, the present disclosure also provides an operating method of the display driver.

Fig. 5 illustrates a flow diagram of a method 500 of operation of a display driver in accordance with at least one embodiment of the present disclosure. The method of operating the display driver includes steps S510 to S520.

The operation method of the display driver described with reference to fig. 5 may be applied to the display driver described with reference to fig. 4A or the display driver described with reference to fig. 4B. The display driver is adapted for a vehicle and includes an image capture device input unit directly connected to an image capture device via a transmission medium in the vehicle and a display drive unit connected to a display panel.

In step S510, first image data from an image pickup device is received by an image pickup device input unit.

In step S520, the display driving unit receives the first image data from the image capturing device input unit, and drives the display panel to display using the first image data.

In this way, the operation method of the display driver according to at least one embodiment of the present disclosure may enable the display driver to be directly connected to the image capture device and to drive the image data output from the image capture device for display, thereby avoiding a display delay of the image data caused by a processor (e.g., an ECU) needing to process the image data from all cameras and then send the processed image data to the display driver for display.

Additional aspects of the method 500 for operating a display driver according to at least one embodiment of the present disclosure may correspond to methods performed by the respective units/modules of the display driver described with reference to fig. 4A or 4B, and technical effects of the respective units/modules of the display driver described with reference to fig. 4A or 4B may also be mapped to these additional aspects, which are not repeated herein.

In the display system 700 of fig. 7, the monitor may include a left monitor 709 and a right monitor 710. Of course, embodiments are not so limited, for example, in display system 700 of FIG. 7, the monitor may also include a primary monitor 708, even though it is not necessary that primary monitor 708 be directly connected to the image capture device via a transmission medium.

The processor 707 may be connected to a display driver of a monitor. The processor 707 may be configured to perform data image processing on the received image data and to transmit the result of the data image processing to a driver of the monitor. For example, referring to fig. 7, processor 707 may be connected to left monitor 709 or right monitor 710 via a transmission medium or other connection as described above.

The image capturing device may be, for example, the image capturing device described with reference to fig. 4A and 4B.

In the display system 700 of fig. 7, the image capture device may include a left camera 703 and a right camera 704. The left camera 703 may be connected directly to the left monitor 709 via a transmission medium and the right camera 704 may be connected directly to the right monitor 710 via a transmission medium.

As such, the display system according to at least one embodiment of the present disclosure may allow the monitor to be directly connected to the image pickup device and drive the image data output from the image pickup device for display, avoiding a display delay of the image data caused by a processor (ECU) needing to process the image data from all the cameras and then send the processed image data to the display driver for display.

In some embodiments, with continued reference to fig. 7, the display system 700 may also include additional image capture devices (e.g., front camera 701, rear camera 702, steering camera 705, for example) that may be directly connected to the processor 707 (e.g., via a transmission medium or other connection as described above). In this manner, the processor can receive image data from the additional image capture device for processing via the direct connection, and thus, the image data received by the processor can be from the additional image capture device directly connected to the processor.

In some embodiments, the image data received by the processor may come from a display driver of the monitor (e.g., see fig. 4B, output via the transit output unit 430 in the display driver 400).

In some embodiments, the additional image capture device may be different from or non-coincident with the image capture device. For example, with continued reference to fig. 7, the additional image capture devices are a front camera 701, a rear camera 702, and a driving camera 705, while the image capture devices are a left camera 703, a right camera 704. In this way, it can be avoided, for example, that the camera adds an additional connector for transmitting its image data to the processor, which is particularly advantageous in the case that the image data of the image acquisition device can already be displayed by the monitor by direct connection via the transmission medium, or the monitor can transmit the image data acquired from the image acquisition device to the processor via the transmission medium.

In some embodiments, a direct connection of the image capture device to the processor may be established instead of or in addition to a connection where the monitor may transmit image data obtained from the image capture device to the processor. For example, with continued reference to fig. 7, a direct connection of the left camera 703 to the processor 707 may be established instead of or in addition to the connection of the left monitor 709 to the processor 707.

In some embodiments, with continued reference to fig. 7, the display system 700 may also include an additional monitor (e.g., a main monitor 708) that may be connected to the processor 707 (e.g., via a transmission medium or other connection as described above). The additional monitor may be, for example, the display driver 400 described with reference to fig. 4A or 4B, or may be, for example, the monitor 300 described with reference to fig. 3.

In some embodiments, the image capture device or additional image capture devices may include a front camera for capturing image data forward of the vehicle, a rear camera for capturing image data rearward of the vehicle, a left camera for capturing image data of a left side of the vehicle, a right camera for capturing image data of a right side of the vehicle, or a drive camera for capturing image data of an interior of the vehicle.

Additional aspects of processor 707 may be found in the processors described in conjunction with fig. 1-4A and 4B, and additional aspects of the display drivers of monitors 709-710 may be found in the display drivers described in conjunction with fig. 4A and 4B and will not be described in detail herein.

It will be appreciated that the display system 700 and its various elements described in fig. 7 are merely exemplary and that other variations are possible. For example, the cameras 701-705 shown in FIG. 7 may alternatively be any other device that can acquire image data. Also for example, the number of cameras 701-705 and monitors shown in FIG. 7 may vary. Also for example, the number of cameras connected directly to the monitor via the transmission medium may also vary. As another example, a camera connected directly to a monitor via a transmission medium may be one or more of cameras 701-705. For another example, the corresponding relationship between the camera and the monitor may also be changed (e.g., the left camera 703 may be directly connected to the right monitor 710 or the main monitor 708 via a transmission medium, which is not limited in this disclosure).
