[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

The terminal and the server may be directly or indirectly connected via wired or wireless communication, and this application does not limit this.

[0049] See also Figure 1, taking the display control device integrated into the control device as an example, Figure 1 A schematic diagram of an implementation scenario of the display control method provided in an embodiment of the present application, wherein the control device may be a terminal device, which controls the display device to rotate in response to a target request; and controls the image acquisition device to perform image processing on the acquired original image to obtain a target image that matches the rotated display device, and transmits the target image to the display device for display.

[0050] It should be noted that Figure 1 The implementation environment scenario diagram of the display control method shown is only an example. The implementation environment scenario of the display control method described in the embodiment of the present application is to more clearly illustrate the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided by the embodiment of the present application. It is known to those skilled in the art that with the evolution of data processing and the emergence of new business scenarios, the technical solution provided by the present application is also applicable to similar technical problems.

[0051] The solutions provided by the embodiments of the present application are specifically described by the following embodiments. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0052] The embodiments of the present application will be described from the perspective of a display control device, which can be specifically integrated into an image acquisition device, a control device, and a display device. The control device can be a terminal and / or a server, and the present application does not limit this.

[0053] See also Figure 2 , Figure 2 1 is a flow chart of a display control method provided by an embodiment of the present application. The display control method is applied to an image acquisition device, the image acquisition device is connected to a control device, and the control device is also connected to a display device independently provided from the image acquisition device. The display control method may include the following steps S101 to S103:

[0054] S101. Receive a target instruction from a control device, where the target instruction is triggered by the control device controlling a display device to rotate.

[0055] Among them, the target instruction refers to an instruction triggered after the control device controls the display device to rotate, and is used to control the image acquisition device to perform image processing on the acquired original image based on the target instruction to obtain a target image that matches the rotated display device.

[0056] The specific type of the control device can be adjusted according to the actual situation, and the embodiment of the present application does not limit it. For example, the control device is a vehicle-mounted host. For another example, the control device is a server device remotely connected to the image acquisition device and the display device.

[0057] The display device is rotatable. Rotation means that the display device can change its screen orientation. For example, the screen orientation of the display device rotates from a horizontal screen to a vertical screen.

[0058] The specific type of the display device can be adjusted according to actual conditions, and the embodiment of the present application does not limit it. For example, the display device is a vehicle-mounted tablet. For another example, the display device is a liquid crystal display screen in the cockpit.

[0059] S102: Based on the target instruction, perform image processing on the collected original image to obtain a target image that matches the rotated display device.

[0060] The image processing refers to a series of processing processes for processing the original image into an image that matches the display state of the display device after rotation, which can be adjusted according to actual conditions and is not limited in the embodiments of the present application.

[0061] The target image refers to an image that matches the rotated display device. That is, the target image meets the display requirements of the rotated display device. For example, when the screen orientation of the rotated display device is vertical, the target image is a vertical image with good display effect.

[0062] S103: Transmit the target image to the display device, so that the rotated display device performs display based on the target image.

[0063] There are many ways to transmit the target image to the display device, which can be adjusted according to actual conditions, and the embodiments of the present application do not limit it. For example, the target image is transmitted to the display device through the physical connection between the image acquisition device and the display device. For another example, the target image is transmitted to the control device through the image acquisition device, and the target image is transmitted to the display device through the control device.

[0064] The display control device for image acquisition devices provided in the embodiment of the present application receives a target instruction from a control device, and the target instruction is triggered based on the control device controlling the display device to rotate; based on the target instruction, the captured original image is processed to obtain a target image that matches the rotated display device; and the target image is transmitted to the display device so that the rotated display device is displayed based on the target image. In this way, the target instruction sent by the control device to the image acquisition device is triggered based on the rotation of the display device, so that the image acquisition device independently set up in the display device performs a series of processing on the captured original image to obtain an image that meets the display requirements of the rotated display device, thereby improving the display effect of the image captured by the image acquisition device in the display device and improving the user experience.

[0065] It should be noted that there are many ways to process images, which can be adjusted according to actual conditions and are not limited in the embodiments of the present application.

[0066] In some optional embodiments, the above-mentioned process of performing image processing on the captured original image based on the target instruction to obtain a target image that matches the rotated display device may include: based on the target instruction, performing image processing on at least part of the picture content in the captured original image to obtain a target image that matches the screen direction of the rotated display device.

[0067] The screen orientation includes horizontal orientation, vertical orientation, and the screen orientation after being rotated by a predetermined angle (such as 45°, 75°).

[0068] There are many ways to perform image processing on at least part of the image content in the captured original image, which can be adjusted according to actual conditions and are not limited in the embodiments of the present application.

[0069] In some optional embodiments, the above-mentioned process of performing image processing on at least part of the screen content in the captured original image based on the target instruction to obtain a target image that matches the screen direction of the rotated display device may include: based on the target instruction, cropping at least part of the screen content from the original image to obtain a cropped image; rotating the cropped image to obtain a target image that matches the screen direction of the rotated display device.

[0070] The cropped image refers to an image obtained by cropping at least a portion of the picture content from the original image.

[0071] The target image refers to an image obtained by rotating the cropped image.

[0072] In some optional embodiments, the target instruction may include cropping position information.

[0073] The cropping position information is used to indicate the position information of the part of the picture content that needs to be cropped in the original image.

[0074] Based on this, the above process of cropping at least part of the picture content from the original image based on the target instruction to obtain a cropped image may include: determining the target picture content that needs to be retained in the original image based on the cropping position information; cropping the target picture content from the original image to obtain a cropped image.

[0075] The target image content is used to indicate the image content that needs to be retained in the original image.

[0076] In some optional embodiments, the cropping position information includes cropping length information in the image direction.

[0077] Here, the image direction refers to the row or column of the image, which can be adjusted according to the actual situation and is not limited in the embodiment of the present application.

[0078] The cropping length information refers to the length information of the screen content that needs to be retained in the original image in the image direction, which can be adjusted according to actual conditions and is not limited in the embodiment of the present application. For example, if the cropping length information is 608 columns, it means that the image direction is columns, and the length of the screen content that needs to be retained is 608 columns.

[0079] Based on this, the process of determining the target picture content to be retained in the original image based on the cropping position information may include: determining the target picture content to be retained in the original image based on the cropping length information.

[0080] In some optional embodiments, the above-mentioned cropping position information also includes offset information.

[0081] The offset information is used to indicate the information that the content of the original image to be retained needs to be offset, which can be adjusted according to the actual situation and is not limited in the embodiment of the present application. For example, the offset information is 2 columns to the right, which means that when the target image content is in the column direction, it is offset to the right by two columns, so that the cropped image is at the center of the field of view of the image acquisition device.

[0082] Based on this, the process of cropping the target picture content from the original image to obtain a cropped image may include: cropping the target picture content from the original image, offsetting the target picture content according to the offset information, and obtaining a cropped image at the center of the field of view of the image acquisition device.

[0083] In some optional embodiments, the above-mentioned process of rotating the cropped image to obtain a target image that matches the screen direction of the rotated display device includes: performing row-column conversion on the cropped image to obtain a target image that matches the screen direction of the rotated display device.

[0084] The row-column transformation process is used to indicate the process of transforming the rows and columns of the image, which can be adjusted according to the actual situation and is not limited in the embodiments of the present application. For example, the row-column transformation process is to transform the rows of the cropped image into the columns of the target image, and transform the columns of the cropped image into the rows of the target image.

[0085] In some optional embodiments, before transmitting the target image to the display device, the display control method further includes: scaling the target image to obtain a target image that matches the screen size of the display device.

[0086] There are many ways to perform scaling, which can be adjusted according to actual conditions and are not limited in the embodiments of the present application.

[0087] For example, the target image is directly scaled according to a preset ratio to obtain a target image that matches the screen size of the display device.

[0088] For another example, by performing bilinear interpolation processing on the target image, a target image matching the screen size of the display device is obtained.

[0089] Bilinear interpolation refers to interpolation from multiple dimensions. The core idea is to perform linear interpolation in two directions respectively.

[0090] See also Figure 3 , Figure 3 is a specific calculation diagram of the bilinear interpolation process provided by the embodiment of the present application. Figure 3 As shown, the goal is to obtain the pixel value of the unknown function f at the green point P(x,y). The coordinates of Q11(x1,y1), Q12(x1,y2), Q21(x2,y1), Q22(x2,y2) and the corresponding pixel values ​​are known. First, interpolate in the x direction to obtain R1 and R2, and then interpolate in the y direction to obtain P. The calculation formulas for R1 and R2 are shown in the following formula (1):

[0091]

[0092] Interpolate in the y direction according to the following formula (2):

[0093]

[0094] Combining formula (1) and formula (2), the final pixel value can be obtained.

[0095] It should be noted that the image after cropping and rotation can be scaled and adjusted in resolution by interpolation (i.e., using the grayscale values ​​or RGB three-color values ​​of known adjacent pixels to generate the grayscale values ​​or RGB three-color values ​​of unknown pixels, with the purpose of regenerating an image with higher resolution from the original image) to obtain a vertical screen image with unchanged resolution. Monolinear interpolation only uses the corresponding values ​​of two points to extrapolate, which will cause a large error in the result. In order to reduce the error, the embodiment of the present application preferably adopts bilinear interpolation processing.

[0096] In some optional embodiments, after scaling the target image to obtain a target image that matches the screen size of the display device, the display control method further includes: performing image quality enhancement processing on the target image to obtain a target image after image quality enhancement processing; wherein the image quality enhancement processing includes at least one of brightness adjustment processing, color adjustment processing, contrast adjustment processing, transparency adjustment processing, clarity adjustment processing, and noise control processing.

[0097] In some optional embodiments, before cropping at least part of the picture content from the original image based on the target instruction to obtain the cropped image, the display control method also includes: performing image quality enhancement processing on the original image to obtain the original image after image quality processing; wherein the image quality enhancement processing includes at least one of brightness adjustment processing, color adjustment processing, contrast adjustment processing, transparency adjustment processing, clarity adjustment processing, and noise control processing.

[0098] In some optional embodiments, before cropping at least part of the picture content from the original image based on the target instruction to obtain the cropped image, the display control method also includes: determining the application scenario of the image acquisition device and setting the working mode of the image acquisition device according to its application scenario.

[0099] Exemplarily, when the ambient brightness of the working environment of the image acquisition device is high, the working mode of the image acquisition device is set to the general color gamut working mode; when the ambient brightness of the working environment of the image acquisition device is low, the working mode of the image acquisition device is set to the wide color gamut working mode. Among them, the working mode with a color gamut range higher than 72% NTSC is called the wide color gamut working mode, and the working mode with a color gamut range lower than 72% NTSC is called the general color gamut working mode.

[0100] See also Figure 4 and Figure 5 The above content is explained below with a specific embodiment.

[0101] Figure 4 It is a result schematic diagram of a display control method of a prior art in a vehicle scenario provided by an embodiment of the present application. It should be noted that in a vehicle scenario, some users have less and less time to meet with family and friends due to frequent business trips, and can only meet with family and friends through video calls, and the vehicle's display tablet (i.e., display device) is large enough, and a good experience can be obtained when video chatting with family and friends through the vehicle's display tablet. Video calls require the use of an in-car camera. Applications such as WeChat on the display tablet will automatically rotate the screen direction of the display tablet when calling the camera function for video calls, that is, the display tablet changes from the original horizontal screen to the vertical screen. However, the inventors have found that due to resolution reasons, when the display tablet is in portrait mode, the image will be centered in the middle of the screen, and there will be a lot of black borders on the top and bottom of the screen (such as Figure 4 The existing software can only compensate for the image, and cannot make the image resize adaptively with the screen rotation to remove the black edges. If the image is manually rotated to vertical (such as Figure 4 (As shown in the third image, although there is no black border, the picture is rotated 90°. This design affects the display effect of the image collected by the camera on the display device, reducing the user experience.

[0102] In order to solve the above problems, the present application provides the following embodiments: Figure 5 The result schematic diagram of the display control method in the vehicle scene is shown. The display device provided in the present application is still the display tablet of the vehicle, and the image acquisition device refers to a camera that is arranged inside the vehicle and cannot rotate. For example, a camera installed under the glasses box in the car. Through the various applications on the display tablet, the camera function can be called to open the camera. For example, WeChat can make WeChat videos by calling the camera function, short video software such as Douyin and Kuaishou can make videos by calling the camera function, and Tencent Conference can also conduct video conferences by calling the camera function. The image acquisition device of the embodiment of the present application is equivalent to the front camera configured in the mobile phone, but the difference is that when the mobile phone is rotated, its front camera will rotate with it, while the camera of the embodiment of the present application is fixed in the installation position, and the camera cannot rotate when the vehicle-mounted display tablet is rotated. In order to solve the above problems, the image can be cropped by the image signal processing module (Image Signal Processing, ISP) on the camera, and the image can be obtained by rotating and scaling. Figure 5 The vertical screen image with a resolution of 1920*1080 is shown. The image at this time has fewer pixels and a smaller field of view than the original image. When using third-party software to shoot videos, such as WeChat calls, people often only need to record themselves in the video and do not need too much video screen, so a smaller field of view can just meet the needs.

[0103] Specifically, after the user sets the vehicle to parking mode in the car, he opens third-party applications such as Douyin, Kuaishou, WeChat Video, and Tencent Conference according to entertainment or office needs. After entering the third-party application, the user clicks the capture video or record video button to start calling the camera function. The camera selects the camera's working mode according to different application scenarios. When the ambient brightness of the camera's working environment is high, the camera's working mode is set to the general color gamut working mode; when the ambient brightness of the camera's working environment is low, the camera's working mode is set to the wide color gamut working mode. The working mode with a color gamut range higher than 72% of the color gamut standard (National Television Standards Committee, NTSC) is called a wide color gamut working mode, and the working mode with a color gamut range lower than 72% of the NTSC is called a general color gamut working mode. After the host (i.e., the control device) receives the camera call instruction, it will continue to supply power to the camera, and the camera starts working. The camera converts the optical signal into an electrical signal, and then transmits the image data to the camera's ISP for preliminary image processing. ISP adjusts brightness through automatic exposure module, lens correction, etc., adjusts color through automatic white balance, saturation enhancement and suppression, chroma denoising, saturation suppression of dynamic range curve, false color removal, etc., adjusts contrast and transparency through gamma, etc., and adjusts clarity and noise control through sharpening, interpolation, brightness denoising, etc. The image preliminarily processed by ISP is transmitted to the system on a chip (SOC) on the host side through the first serializer. At this time, the signal is a MIPI-CSI signal, which is only applicable to the camera. SOC converts MIPI-CSI signal into MIPI-DSI, and then transmits image data to the display screen for display through the second serializer. The host sends a command to rotate 90 degrees clockwise to the motor responsible for rotating the display panel, and the display panel rotates from horizontal screen to vertical screen. When the user in the car speaks, the voice engine identifies the direction of the sound in the car, and determines whether it is the main driver's seat, the co-driver's seat, or the back seat according to the direction of the sound in the car. The result of the voice engine can be called by SOC. If the sound source comes from the main driver's seat, the cropping area is determined to be the main driver's seat, and the corresponding register 0x01 is sent to the first deserializer; if the sound source comes from the co-pilot seat, the cropping direction is determined to be the co-pilot seat, and the corresponding register 0x02 is sent. The pixels of the cropped area are 608*1080. Based on the above content, the cropping instruction (i.e., the target instruction) is generated. The SOC sends the cropping instruction to the first deserializer through a bidirectional two-wire synchronous serial bus (Inter-Integrated Circuit, I2C), and then sends the cropping instruction to the camera through transparent transmission. The ISP on the camera receives the cropping instruction and crops the image. When cropping, it first measures the picture to be cropped, writes the length information and / or offset information of the ISP, and keeps the cropped picture in the center of the camera's field of view.The cropped image is placed in the double data rate synchronous dynamic random access memory (DDR) for data rearrangement (image rotation), and then the resolution is proportionally scaled by interpolation. The image quality of the cropped and rotated image is adjusted. The image with adjusted image quality is first transmitted to the host's SOC through the first deserializer, and then transmitted to the display panel through the second deserializer for image display.

[0104] See also Figure 6 , Figure 6 1 is a flow chart of a display control method provided by an embodiment of the present application. The display control method is applied to a control device, the control device is connected to a display device and an image acquisition device, and the image acquisition device is independently arranged on the display device. The display control method may include the following steps S201 to S202:

[0105] S201: In response to a target request, control a display device to rotate.

[0106] The target request refers to a request for controlling a display device to rotate and controlling an image acquisition device to obtain a target image.
