Description

Technical Field

[0001] The present application relates to communication technology, and in particular to an image display system. Background Art

[0002] The electronic rearview mirror is a system composed of a camera and a monitor. It is a new type of indirect vision device that needs to see the rear and side vision of the vehicle clearly within the specified field of view. Compared with traditional lens-type rearview mirrors, electronic rearview mirrors have the advantages of small blind spots, less impact from the natural environment, and less wind resistance, which brings safer and more economical driving experience to drivers.

[0003] With the upgrade and iteration of basic imaging optical technology, cameras of different specifications are used to collect Class II field of view images, Class IV field of view images, Class V field of view images, and Class VI field of view images, and present them on electronic rearview mirrors respectively. If you need to achieve full coverage of Class II field of view images, Class IV field of view images, Class V field of view images, and Class VI field of view images, you need to use multiple electronic rearview mirrors. In the traditional solution, full coverage of the traditional rearview mirror Class II, IV, V, and VI fields of view is achieved through three sets of independent electronic rearview mirror device systems. However, the more electronic rearview mirror device systems there are, the more driving interference it will cause to the driver, thereby affecting driving safety.

[0004] Therefore, how to present a full coverage field of view image in a smaller number of electronic rearview mirrors to improve driving safety still needs to be considered. Utility Model Content

These drawings and text descriptions are not intended to limit the scope of the present disclosure in any way, but to illustrate the concepts of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0090] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0091] In the description of the present application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature. In the description of the present application, "plurality" means two or more, unless otherwise clearly and specifically defined.

[0092] First, the terms involved in this application are explained:

[0093] Category II field of view image: Category II field of view image is used to present the main external rear field of view of the vehicle.

[0094] Category IV field of view images: Category IV field of view images are used to present the vehicle's wide-angle external field of view.

[0095] Five types of field of view images: Category V field of view image, used to present the vehicle's blind external field of view.

[0096] Category VI field of view image: Category VI field of view image is used to present the vehicle's forward field of view.

[0097] The electronic rearview mirror is a system composed of a camera and a monitor. It is a new type of indirect vision device that needs to see the rear and side vision of the vehicle clearly within the specified field of view. Compared with traditional lens-type rearview mirrors, electronic rearview mirrors have the advantages of small blind spots, less impact from the natural environment, and less wind resistance, which brings safer and more economical driving experience to drivers.

[0098] With the upgrade and iteration of basic imaging optical technology, cameras of different specifications are used to collect Class II field of view images, Class IV field of view images, Class V field of view images, and Class VI field of view images, and present them on electronic rearview mirrors respectively. If you need to achieve full coverage of Class II field of view images, Class IV field of view images, Class V field of view images, and Class VI field of view images, you need to use multiple electronic rearview mirrors. In the traditional solution, full coverage of the traditional rearview mirror Class II, IV, V, and VI fields of view is achieved through three sets of independent electronic rearview mirror device systems. However, the more electronic rearview mirror device systems there are, the more driving interference it will cause to the driver, thereby affecting driving safety.

[0099] Therefore, how to present full coverage of Class II, IV, V, and VI field of view images in a smaller number of electronic rearview mirrors to improve driving safety still needs to be considered.

[0100] Based on this, the present application provides an image display system. The image display system includes a first electronic rearview mirror device and a second electronic rearview mirror device. The first electronic rearview mirror device is used to collect and display two types of field of view images and four types of field of view images. The second electronic rearview mirror device is used to collect and display two types of field of view images, four types of field of view images, five types of field of view images, and six types of field of view images.

[0101] That is, one electronic rearview mirror device is used to display the II / IV field of view image on the driver's side, and the other electronic rearview mirror device is used to display the II, IV, V, and VI field of view images on the co-pilot side. For example, in a left-hand drive vehicle, the driver is on the left side, and the first electronic rearview mirror device is set on the left side of the vehicle body to collect and display the field of view image of the left rear of the vehicle body (or the driver's side). The second electronic rearview mirror device is set on the right side of the vehicle body to collect and display the field of view image and blind spot / forward field of view image of the right rear of the vehicle body (or the co-pilot's side). In a right-hand drive vehicle, the driver is on the right side, and the first electronic rearview mirror device is set on the right side of the vehicle body to collect and display the field of view image of the right rear of the vehicle body (or the driver's side). The second electronic rearview mirror device is set on the left side of the vehicle body to collect and display the field of view image and blind spot / forward field of view image of the left rear of the vehicle body (or the co-pilot's side). Therefore, the number of electronic rearview mirrors is reduced while presenting full coverage of Class II, IV, V, and VI visual field images. The driver can see the full coverage visual field images through two electronic rearview mirror devices, thereby improving driving safety.

For example, in a left-hand drive vehicle, the driver is on the left side, and the first electronic rearview mirror device 100 is set on the left side of the vehicle body to collect and display the field of view image of the left rear of the vehicle body (or the driver's side). The second electronic rearview mirror device 200 is set on the right side of the vehicle body to collect and display the field of view image and blind spot / forward field of view image of the right rear of the vehicle body (or the co-pilot side).

After reading the value of the ambient light intensity, the read value is converted into a brightness value through multiple algorithms and an anti-shake mechanism. The first control unit 1221 is also used to control the operation of the first backlight control unit 1226 according to the ambient light information to adjust the display of the first display screen 121. The first backlight control unit 1226 is used to drive the backlight display of the first display screen 121. The first control unit 1221 adjusts and outputs the backlight display brightness value of the first display screen 121 through the PWM (Pulse Width Modulation, referred to as pulse width modulation) duty cycle.

[0120] For example, when the ambient light is too bright, the first backlight control unit 1226 is controlled to increase the display brightness of the first display screen 121 ; when the ambient light is too dark, the first backlight control unit 1226 is controlled to reduce the display brightness of the first display screen 121 .

[0121] The first backlight detection unit 1224 is used to output backlight detection information, and the backlight detection information at least includes backlight temperature. Figure 5 The first control unit 1221 is used to receive the backlight detection information and control the operation of the first backlight control unit 1226 according to the backlight detection information to adjust the display of the first display screen 121. For example, when the backlight temperature is too high, the display brightness of the first display screen 121 is lowered, and when the backlight temperature is too low, the display brightness of the first display screen 121 is increased. The backlight circuit of the first display screen 121 also has overvoltage protection, overcurrent protection and short circuit protection, and the first backlight detection unit 1224 can also detect fault information such as open circuit or short circuit of the backlight circuit.

[0122] Optional, see Figure 6, the first controller 122 also includes a first transceiver 1227, a first storage unit 1228 and a first power supply unit 1229. The first transceiver 1227 is used to receive a vehicle body CAN (Controller Area Network) signal, and the first control unit 1221 is used to decode the vehicle body CAN signal received by the first transceiver 1227, and decode the vehicle body CAN signal. The decoded information includes, for example, gear information, door opening and closing information, vehicle speed information, steering information, etc., so that the communication of gear information, door opening and closing information, vehicle speed information, steering information, etc. is realized. Correspondingly, by processing the image information collected by the first acquisition device 110 through the first image processing unit 1222, the field of view image of the vehicle in the conventional scene, steering scene, reversing scene, panoramic scene, etc. can be controlled to be displayed on the first display screen 121.

[0123] The first storage unit 1228 is used to store a preset brightness value range, which can be used to regulate the display brightness of the first display screen 121. It is also used to store the ambient light brightness value.

[0124] The first power supply unit 1229 is used for supplying power.

[0125] See also Figure 7 In one embodiment of the present application, the second controller 222 includes a second control unit 2221, a second image processing unit 2222, a second ambient light sensing unit 2223, a second backlight detection unit 2224, a second backlight control unit 2225, a second deserializer 2226, and a serializer 2227. The third display device 240 includes a third deserializer 242, a third display screen 241, and a backlight circuit 243.

[0126] The second control unit 2221 is signal-connected to the second image processing unit 2222 , the second ambient light sensing unit 2223 , the second backlight detection unit 2224 , and the second backlight control unit 2225 .

[0127] The input end of the second deserializer 2226 is connected to the signal of the second acquisition device 210, and the output end is connected to the signal of the second image processing unit 2222. The input end of the serializer 2227 is connected to the output signal of the second image processing unit 2222, and the output end is connected to the input signal of the third deserializer 242. The second deserializer 2226 is used to process the images collected by the second acquisition device 210 and the third acquisition device 230 and send the information to the second image processing unit 2222.

[0128] The second image processing unit 2222 is used to generate the second video signal and the third video signal according to the information sent by the second deserializer 2226, and is also used to output the second video signal to the second display screen to display the image, and output the third video signal to the serializer 2227. The serializer 2227 is used to output information based on the third video signal to the third deserializer 242. The third deserializer 242 is used to generate the third video signal according to the information sent by the serializer 2227 and then output it to the third display screen 241 to display the image.

[0129] The second image processing unit 2222 is connected to the third display screen 241 via a coaxial cable. After being processed by the second image processing unit 2222, the five-field image and the six-field image are transmitted to the third deserializer 242 via a coaxial cable (GMSL protocol transmission) and converted into LVDS signals for display on the third display screen 241.

[0130] The second ambient light sensing unit 2223 is used to detect ambient light and output ambient light information. The second ambient light sensing unit 2223 is installed between the metal frame and the cover plate of the second display screen 221. The second ambient light sensing unit 2223 can be connected to the first control unit 1221 through a flexible flat cable (FFC cable). The second ambient light sensing unit 2223 includes an ambient light sensor, see Figure 4 After the ambient light sensor collects the ambient light data, the second control unit 2221 obtains the brightness value of the ambient light through the data filtering algorithm, the brightness adjustment hysteresis algorithm and the brightness gradient processing algorithm. Specifically, the second control unit 2221 communicates with the ambient light sensor through I2C. After the vehicle is started, the ambient light sensor is initialized first. After reading the value of the ambient light intensity, the read value is converted into a brightness value through multiple algorithms and anti-shake mechanisms. The second control unit 2221 is also used to control the operation of the second backlight control unit 2225 according to the ambient light information to adjust the display of the second display screen 221. For example, when the ambient light is too bright, the display brightness of the second display screen 221 is increased, and when the ambient light is too dark, the display brightness of the second display screen 221 is reduced. It should be noted that for the display of the second field of view image and the fourth field of view image, the display of the fifth field of view image and the sixth field of view image, one second ambient light sensing unit 2223 can be shared, or one second ambient light sensing unit 2223 can be used respectively.

[0131] The second backlight detection unit 2224 is used to output backlight detection information, and the backlight detection information at least includes backlight temperature. Figure 5, the second control unit 2221 is used to receive the backlight detection information, and control the second backlight control unit 2225 to operate according to the backlight detection information to adjust the display of the second display screen 221. For example, when the backlight temperature is too high, the display brightness of the second display screen 221 is lowered, and when the backlight temperature is too low, the display brightness of the second display screen 221 is increased. It should be noted that for the display of two-type field of view images and four-type field of view images, and the display of five-type field of view images and six-type field of view images, one second backlight detection unit 2224 can be shared, or one second backlight detection unit 2224 can be used separately. The backlight circuit of the second display screen 221 also has overvoltage protection, overcurrent protection and short circuit protection, and the second backlight detection unit 2224 can also detect fault information such as open circuit or short circuit of the backlight circuit.

[0132] The second backlight control unit 2225 is used to drive the backlight display of the second display screen 221. The second control unit 2221 adjusts and outputs the backlight display brightness value of the second display screen 221 through the PWM duty cycle.

[0133] The second control unit is also used to control the second image processing unit to control the operation of the backlight circuit 243 through the serializer 2227 and the third deserializer 242 to adjust the display of the third display screen 241. There is no need to install an ambient light sensor on the V / VI visual field display assembly. The second image processing unit receives the PWM signal converted from the brightness value of the second ambient light sensing unit after algorithm processing obtained by the second controller, and directly adjusts the backlight driver IC in the V / VI visual field display assembly through transparent transmission according to the GMSL protocol of the SERDES device to change the display brightness of the V / VI visual field display assembly. In the above, by adjusting the display brightness of the first display screen 121, the second display screen and the third display screen 241, the same level of brightness value of different display screens is achieved, and the driver will not be exposed to driving safety risks due to inconsistent brightness changes.

[0134] Optional, see Figure 8, the second controller 222 also includes a second transceiver 2228, a second storage unit 2229 and a second power supply unit 2230. The second transceiver 2228 is used to receive the vehicle body CAN signal, and the second control unit 2221 is used to decode the vehicle body CAN signal received by the second transceiver 2228, and decode the vehicle body CAN signal. The decoded information includes, for example, gear information, door opening and closing information, vehicle speed information, steering information, etc., so that the communication of gear information, door opening and closing information, vehicle speed information, steering information, etc. is realized. Correspondingly, the second image processing unit 2222 processes the image information collected by the second acquisition device 210, and can control the second display screen 221 to display the field of view image of the vehicle in the conventional scene, steering scene, reversing scene, panoramic scene, etc.

[0135] The second storage unit 2229 is used to store a preset brightness value range, and the preset brightness value range can be used to regulate the display brightness of the second display screen 221.

[0136] The second power supply unit 2230 is used for supplying power.

[0139] When the first electronic rearview mirror device 100 displays two types of visual field images and four types of visual field images, the first image processing unit 1222 processes the image collected by the first acquisition device 110, and then controls the first display screen 121 to display the image collected by the first acquisition device 110. The first control unit 1221 can also adjust the backlight display of the first display screen 121 according to the ambient light, backlight display temperature, etc. When the second electronic rearview mirror device 200 displays two types of visual field images, four types of visual field images, five types of visual field images, and six types of visual field images, the second image processing unit processes the images collected by the second acquisition device 210 and the third acquisition device 230, and then controls the second display screen 221 to display the image collected by the second acquisition device 210 and controls the third display screen 241 to display the image collected by the third acquisition device 230. The second control unit can also adjust the backlight display of the second display screen 221 and the third display screen 241 according to the ambient light, backlight display temperature, etc. In this way, the number of electronic rearview mirrors is reduced while presenting a fully covered field of view image. The driver can see the fully covered field of view image through two electronic rearview mirrors (such as the left electronic rearview mirror and the right electronic rearview mirror), thereby improving driving safety.
