Description

Technical Field

[0001] This application relates to the field of video communication technology, and in particular to a data acquisition device and a display device. Background Technology

[0002] With the development of 4G and 5G technologies, video communication and video conferencing applications are becoming increasingly widespread. In the field of video communication, a common solution is a hardware-based acquisition system that uses cameras to capture, transmit, and process viewpoints. After acquiring image data, a viewpoint synthesis scheme is used to combine the high-quality images captured at high speed by the RGB camera into a 3D scene. Finally, the 3D scene is displayed on a 3D light field monitor, achieving a real-time and authentic interactive experience.

[0003] Currently, acquisition devices used to capture 3D scene images, such as RGB camera arrays, are typically integrated into display devices, such as televisions or computer monitors. However, these devices are not essential peripherals for display devices. Integrating them into the display device increases manufacturing costs, increases display device size, and affects the normal operation of the display device when no video communication is being conducted. Furthermore, acquisition systems integrated into display devices cannot quickly and easily adjust audio and video signal acquisition to meet different needs. Summary of the Invention

[0053] Embodiments of the present disclosure will now be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the disclosure. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of the present disclosure.

[0054] The accompanying drawings illustrate various structural schematics according to embodiments of the present disclosure. These drawings are not to scale, and some details have been enlarged for clarity, and some details may have been omitted. The shapes of the various regions and layers shown in the drawings, as well as their relative sizes and positional relationships, are merely exemplary and may deviate from reality due to manufacturing tolerances or technical limitations. Furthermore, those skilled in the art can design regions / layers with different shapes, sizes, and relative positions as needed.

[0055] In the context of this disclosure, when a layer / element is referred to as being "above" another layer / element, the layer / element may be directly above the other layer / element, or there may be an intermediate layer / element between them. Additionally, if a layer / element is "above" another layer / element in one orientation, then when the orientation is reversed, the layer / element may be "below" the other layer / element.

[0056] To address the issues of increased manufacturing costs, impaired normal operation, and inconvenient signal acquisition adjustments resulting from integrating the acquisition device into the display device in current video calls or video conferencing, in one optional embodiment, please refer to... Figures 1-12 A data acquisition device is provided, comprising:

[0057] The receiving portion 20 is used to detachably mount at least one object module, the object module including a camera module and / or a microphone module;

[0058] The connecting part 10 includes at least one connector 13, which is used for electrically connecting an object module;

[0059] The fixing part 30 includes a first end and a second end. The first end is connected to the receiving part 20 or the connecting part 10, and the second end is used for detachable connection with the display device.

[0060] Specifically, the accommodating section 20 is used to set one or more object modules. For example... Figure 2As shown, the receiving portion 20 can be elongated and has at least one receiving hole 21, which is used to house one object module. The receiving hole 21 has a first opening on the lower or bottom surface of the receiving portion 20 to allow the object module to be mounted on the connector 13. The receiving hole 21 may have a second opening on its side or top surface to allow the object module, such as a camera module or microphone module, to acquire corresponding audio and video signals through the second opening. Using the receiving hole 21 to house or install the object module facilitates alignment and installation while maintaining the stability of the object module.

[0061] An object module is a data acquisition device used to acquire or respond to data or signals. For example, a camera module is used to acquire image data, and a microphone module is used to acquire audio data. Multiple object modules can be set in the accommodating unit 20, and the arrangement can be adjusted according to actual needs. For example, multiple camera modules can be set in the accommodating unit 20 to form a camera array to acquire video images, or multiple microphone modules can be set to acquire audio signals. Simultaneous acquisition of audio and video signals can also be achieved by simultaneously setting camera modules and microphone modules. In this case, the number and arrangement of camera modules and microphone modules can be adjusted according to actual needs. Alternatively, the object module can also be a camera module that integrates a microphone module.

[0062] The microphone module is used to receive user voice or live audio, and can be applied to light field display 3D video chat or communication.

[0063] The camera module can utilize a light field camera. Compared to traditional video communication, light field imaging offers users a more intuitive and realistic interactive experience. A light field is the sum of all light rays emanating from any direction within space. It includes not only information such as the color (wavelength) and intensity of light, but also the direction of light rays, providing a complete description of light propagating through space. The human eye perceives a clear, three-dimensional world by constantly sensing light rays from different positions and directions. A light field, however, completely records and reproduces all the positional and luminous information of the world as perceived by the human eye, thus significantly improving the user experience in video conferencing and video calls. To acquire light field information, a light field camera is needed for image data acquisition. This is because ordinary cameras capture and focus on information about objects in the real world, resulting in a clear focus in the center and blurred edges. Light field cameras, however, record the information flow data of light propagating through space throughout the entire shooting process. After the photo is taken, the focus can be adjusted on a PC to achieve excellent image quality in the video or image.

[0064] Therefore, by using a light field camera to collect and project light rays in all seven dimensions of the total light function, everyone in the environment can simultaneously experience an immersive holographic visual experience. Light field technology, as an ideal 3D display technology, differs significantly from traditional 2D displays: traditional 2D displays can only provide psycho-visual information in five aspects: affine projection, occlusion, lighting and shadow, texture, and prior knowledge. In contrast, light field displays, in addition to generating all the information of traditional 2D displays, can also provide physiological visual information in three aspects: binocular parallax, motion parallax, and focus blur.

[0065] On the other hand, speaker modules can also be used in object modules to enhance the stereo effect of sound emitted by display devices. Stereo perception stems from a person's judgment of the location of sound within space, their assessment of the distance and direction of the sound source, resulting in a realistic spatial listening experience. If this realistically perceived sound is simulated and reproduced using an electroacoustic system, it corresponds to a stereo system. The time delay effect and binaural effect of the human ear are the physiological basis of stereo sound. A stereo system consists of several microphones, transmission paths, and speakers; it is equivalent to moving the sound source in front of the listener, allowing the listener to experience the presence of the sound source in a real spatial distribution.

[0066] It should be noted that the stereoscopic effect of sound mainly relies on the "binaural effect" and the "auricular effect". The binaural effect refers to the fact that when a sound source is not on the central axis directly in front of the ears, the distance to the left and right ears is inconsistent. This results in differences in sound level, time, and phase. These differences are perceived by the ears and transmitted to the brain for analysis and processing, leading to a judgment of the sound source's location.

[0067] Monophasic hearing, utilizing the "auricular effect," also provides a degree of spatial location judgment, complementing the binaural effect. The auricular effect refers to the fact that the human auricle is a complex surface with numerous concave and convex features. The ear canal entrance is not in the center of the auricle. When sound reaches the ear, some sound enters directly into the ear canal, while the rest is reflected at different times by the irregular concave and convex surfaces. These reflected waves and direct waves, under different frequency conditions, create varying time and phase differences, forming a spectral characteristic at the tympanic membrane that is related to the direction of the sound source. The auditory nerve uses this characteristic to determine the location of the sound.

[0068] The minimum angle for human hearing to perceive posture angle is 3°. By recording sound in two channels, it can be played back through two-channel speakers. By utilizing the time difference and intensity difference between the sound and the human ear, a two-channel stereo system can be achieved.

[0069] In addition, the object module can also be a detection module. The detection module detects the position information of the audio / video acquisition object and adjusts the spatial pose of the accommodating part 20 to obtain a better acquisition signal. The detection module can be an infrared detection module or an ultrasonic detection module.

[0070] The reason for placing the detection modules in an external acquisition device is that these modules are not essential peripherals for display devices. Therefore, there is little need to directly integrate the detection modules onto the display. However, in some application scenarios, the functions of these modules are either auxiliary or essential. Therefore, this acquisition device provides a freely combinable and detachable housing 20, which allows different modules to be installed as needed to achieve the desired functionality.

[0071] The connecting part 10 is used for electrically connecting the object module to enable the object module to function properly. The fixing part 30 is used for detachably fixing the acquisition device to the display device. The display device can be a desktop computer monitor, an all-in-one computer monitor, or a conference all-in-one machine, etc.

[0072] In this embodiment, the first end of the fixing part 30 can be connected to the receiving part 20, in which case the receiving part 20 is located between the fixing part 30 and the connecting part 10; the first end can also be connected to the connecting part 10, in which case the connecting part 10 is located between the receiving part 20 and the fixing part 30. Unless otherwise specified, the embodiments disclosed herein are described with the first end being connected to the receiving part 20.

[0073] Therefore, the acquisition device provided in this embodiment allows the entire acquisition device to be detachably mounted on the outside of the display device through the fixing part 30. This allows it to be installed when audio and video signals need to be acquired and detached when acquisition is not needed. Compared with the solution of integrating the acquisition device into the display device, this approach ensures the normal operation of the display device while reducing its cost. On the other hand, the accommodating part 20 and the connecting part 10 support the installation of more than one object module. Combined with the design of the fixing part 30, which is detachably connected to the display device, the type of object module can be easily changed according to needs. For example, a camera module can be installed when video signals need to be acquired, and a microphone module can be installed when audio signals need to be acquired. This allows for convenient and quick customization of the acquisition of different types of signals according to different needs, improving the user experience.

[0074] In this embodiment, the acquisition device may connect to one or more of multiple camera modules, microphone modules, speaker modules, and detection modules as needed. Driving the target module requires corresponding drivers and module identification functionality. Furthermore, the signal data acquired by the target module also needs to be processed; these functional requirements can be implemented by a processor. The processor driving the target module can be an external processor, such as connecting the connection unit 10 to a display device or a main control electronic device, utilizing the processor of the display device or electronic device to drive the target module and process the acquired signals.

[0075] In some alternative embodiments, please refer to Figure 3 An example of a connection part 10 containing a processor is provided, including a base plate 11 and a processing plate 12 fixed on the base plate 11, wherein the processing plate 12 is provided with at least one connector 13; the acquisition device further includes a processor ( Figure 3 (Not shown), is located inside the processing board 12 and is electrically connected to the connector 13. The processor is used to process the audio and video signals collected by the object module.

[0076] Specifically, in this embodiment, the processor and the connector 13 for connecting the object modules are mounted on the processing board 12. The processing board 12 can be a long, strip-shaped plate structure with multiple connectors 13 on its surface. Each connector 13 can be used to connect one object module. The processor can be located inside the processing board 12 or embedded on its surface, and is electrically connected to all the connectors 13 to drive all object modules to acquire signals and process the acquired audio and video signals.

[0077] Considering that the accommodating section 20 may house multiple object modules, please refer to [link / reference needed]. Figure 4 The connector 13 is provided with at least one marking electrode 131 and at least one communication electrode 132. The marking electrode 131 is used to identify the type of the object module, and the communication electrode 132 is used to transmit the data signal of the object module.

[0078] Specifically, when multiple object modules are installed, or when multiple object modules are of different types, the object modules can be self-identified via the marker electrode 131. The configuration of the communication electrode 132 on the connector 13 can be fixed to ensure universality of installation. The difference lies in using the marker electrode 131 as a flag bit, distinguished by electrode signal I / O. For example, taking a light field camera module, a microphone module, and a speaker module as examples, the number of marker electrodes can be set to two, named electrode 1 and electrode 2 for easy differentiation. For the light field camera module, both electrode 1 and electrode 2 are given a low level; for the speaker module, electrode 1 can be high and electrode 2 can be low; for the microphone module, electrode 1 can be low and electrode 2 can be high. Thus, after the object module is installed on the connector 13, the processor's processing chip obtains a digital signal by checking the high and low levels of electrode 1 and electrode 2. For example, receiving 2'b 00 indicates that the object module is a light field camera module; receiving 2'b 10 indicates that the object module is a speaker module; and receiving 2'b 01 indicates that the object module is a microphone module. This allows for self-identification of different object modules, facilitating processor control.

[0079] In some optional embodiments, a positioning mechanism may also be provided in the processing board 12. The positioning mechanism is used to measure the attitude angle of the accommodating part 20, and the processor is used to adjust the position and orientation of the accommodating part 20 according to the attitude angle.

[0080] Specifically, the object module in the receiving section 20 is mounted on the connecting seat 13 of the processing board 12. Therefore, after the positioning mechanism in the processing board 12 measures the attitude angle of the processing board 12, it also simultaneously obtains the attitude angle of the receiving section 20. Based on the attitude angle of the receiving section 20, the spatial pose of the object module can be adjusted, for example, so that the optical axis of the camera module is aligned with the feature of the object being photographed, such as a person's eye, which is beneficial to improving image quality.

[0081] One hardware solution for the positioning mechanism is an accelerometer combined with a magnetometer. The accelerometer can output the three-axis acceleration of the processing board 12 in real time, thereby calculating the pitch angle and roll angle; the magnetometer outputs the three-axis geomagnetic intensity of the processing board 12 in real time, thereby calculating the heading angle. The two work together to calculate the attitude angle information of the processing board 12 or the object module.

[0082] Another hardware solution for the positioning mechanism is to measure the attitude angle or spatial orientation of the accommodating part 20 using horizontal and angle sensors.

[0083] Optionally, the processing board 12 also includes a first communication interface and a second communication interface. The first communication interface is used to connect to the main control device, and the second communication interface is used to connect to the display device. The main control device can be a personal computer or a server. The main control device sends control commands to the acquisition device through the first communication interface to start or stop audio and video acquisition. The second communication interface can be used to transmit the audio and video data acquired by the object module and processed by the processor to the display device for display.

[0084] Optionally, the first and second communication interfaces for connecting external devices can also be located in the housing 20 and connected to the processing board 12 via a data cable.

[0085] Optionally, the processing board 12 also includes a power supply to power the processor and various circuits within it. The power supply can be powered by a button battery. If no power supply is provided, the processing board 12 can be connected to an external power source.

[0086] Optionally, the processing board 12 is also equipped with an analog-to-digital signal conversion chip and a digital-to-analog signal conversion chip for mutual conversion between digital and analog signals.

[0087] For the fixing part 30, its second end is used for detachable and fixed connection with the display device, and its first end is connected to the receiving part 20. The second end can be achieved using a clamp or a snap-fit ​​mechanism. Figure 5 An example is shown where a first clamping end 31 and a second clamping end 32 are provided at the second end of the fixing part 30. The first clamping end 31 is plate-shaped, facilitating clamping on the front of the display device and ensuring flatness and verticality. The second clamping end 32 is cylindrical, either round or square, used to clamp on the back of the display device, ensuring clamping stability. When the first clamping end 31 and the second clamping end 32 are clamped on the upper end of the display device, the weight of the acquisition device itself presses the second clamping end 32 onto the display device, ensuring clamping force.

[0088] Furthermore, the first clamping end 31 and the second clamping end 32 are provided with screw holes. When the first clamping end 31 and the second clamping end 32 are set at the lower end of the display device in an inverted clamping manner, screws can be set in the screw holes to reinforce the connection by means of threaded connection or bolt connection, so as to ensure the stability of the clamping connection between the acquisition device and the display device.

[0089] The receiving part 20 can be rotatably connected to the first end via the rotating mechanism 40, such as Figure 1 and Figure 6As shown. The advantage of a rotary connection is that it allows adjustment of the spatial orientation of the housing 20, improving the acquisition effect of audio and video signals, or the stereo effect of the speaker output. One type of rotary connection is achieved by connecting the first end to the housing 20 via a damping shaft. The damping shaft has an adjustable elastic damper installed on it. When the shaft rotates, the damper generates resistance, which helps to precisely control the rotation angle of the housing 20 and to fix the housing 20 after it has rotated into place.

[0090] In some alternative embodiments, please refer to Figure 7 An optional rotating connection structure is provided, including a hinge ( Figure 7 (Not shown) A locking block 41 and a ratchet 42 are used. The hinge is located between the first end and the receiving part 20, and the ratchet 42 is sleeved on the hinge. The locking block 41 is located in the receiving part 20 and is used to lock the rotation of the hinge when it is engaged with the tooth groove of the ratchet 42, and to unlock the rotation of the hinge when it is moved away from the tooth groove. The locking block 41 can be triangular or wedge-shaped. After being engaged with the tooth groove, it can stop the rotation of the hinge, and when it is moved away from the tooth groove, the hinge can continue to rotate. The ratchet 42 can be provided with multiple tooth grooves. When the locking block 41 is engaged with different tooth grooves, the angle between the fixing part 30 and the receiving part 20 is different, thereby changing the attitude angle of the receiving part 20 and realizing the angle adjustment of the object module to ensure the quality of the acquired audio and video signals.

[0091] The number of grooves can be designed according to requirements. A better approach is to set four grooves, which correspond to the four angle positions of the receiving part 20 relative to the horizontal plane: 30°, 45°, 60°, and 90°, covering the usage needs in most cases.

[0092] Optionally, the rotating connection structure also includes a pull rod 43 or a spring connecting the locking block 41, the pull rod 43 or the spring being used to drive the locking block 41 to engage with the tooth groove or switch the tooth groove. Figure 7 Taking the pull rod 43 as an example, by rotating or pressing the pull rod 43, the locking block 41 is rotated, thereby changing the groove into which the locking block 41 is engaged, or moving the locking block 41 away from the groove. After the hinge rotates to a new angle, the pull rod 43 is reset, and the locking block 41 is re-engaged into the corresponding groove to fix the current orientation or angle of the receiving part 20.

[0093] When the accommodating part 20 and the fixing part 30 are rotatably connected, the attitude angle of the accommodating part 20 can be automatically adjusted according to the position information of the object to be collected detected by the detection module by the processor, or it can be manually adjusted by the user, which can improve the quality of the collected audio and video signals.

[0094] The first end connected to the receiving portion 20 can also be fixedly connected to the receiving portion 20, such as... Figure 8As shown. The fixed connection prevents the accommodating part 20 from being adjusted by rotation, but it offers the advantage of integration. Since a rotating connection mechanism is unnecessary, it simplifies the structure of the acquisition device, making it easier to reduce its overall size. Furthermore, it avoids problems caused by folding or rotation, resulting in lower maintenance and operating costs. It should be noted that because the accommodating part 20 is fixedly connected to the fixing part 30, a second opening can be provided on the side of the accommodating hole 21, allowing the object module to acquire corresponding signal data through this second side opening, such as... Figure 9 As shown.

[0095] Optionally, the shape of the receiving part 20 can be a long, rectangular box. The box-shaped receiving part 20 can accommodate and protect the internal connecting structure or device while making angle adjustment convenient.

[0096] Furthermore, considering that multiple object modules will be housed in the receiving section 20, there are issues regarding the assembly accuracy and ease of assembly for these multiple object modules. Therefore, in some optional embodiments, the acquisition device further includes a number of magnetic modules 50 equal to the number of connecting seats 13. Each magnetic module 50 is disposed between an object module and a connecting seat 13, and the connecting seat 13 is electrically connected to the object module via the magnetic module 50. Please refer to [link / reference]. Figures 10-12 An optional magnetic module 50 structural design is provided. The magnetic module 50 includes a first surface and a second surface. A connection interface 51 for connecting an object module is provided on the first surface. A first magnet (not shown in the figure) and a connection contact 52 for connecting a connecting base 13 are provided on the second surface. A second magnet (not shown in the figure) is provided on the connecting base 13. When the magnetic module 50 is placed between the object module and the connecting base 13, the first magnet and the second magnet attract each other with opposite polarities.

[0097] The introduction of the magnetic module 50 improves the assembly convenience and accuracy of the object module. Specifically, the magnetic module 50 can be cylindrical or rectangular, designed according to actual needs. The second surface of the magnetic module 50 can be considered as the bottom surface, while the first surface can be the top surface or the side surface of the magnetic module 50, designed according to requirements. In this embodiment, the first surface is the top surface of the magnetic module 50.

[0098] A groove can be provided on the second surface of the magnetic module 50 to install the first magnet. Simultaneously, a groove can also be provided on the connecting base 13 to install the second magnet. When assembling the target module, the second surface of the magnetic module 50 is close to the surface of the connecting base 13. At this time, the magnetic poles of the first and second magnets that are close to each other are opposite magnetic poles, thus attracting each other and allowing the magnetic module 50 to be smoothly attached to the connecting base 13. If the magnetic module is placed in the opposite direction, i.e., the first surface is close to the connecting base 13, the magnetic poles of the first and second magnets that are close to each other are in the same direction. This generates a repulsive force, preventing the magnetic module 50 from being placed smoothly.

[0099] In addition, the attraction between the first magnet and the second magnet can also correct the relative position between the magnetic module 50 and the connector 13. This is because the connection contact 52 (Pad) on the second surface of the magnetic module 50 can be aligned with the connector 13 during the connection process by means of the attraction between the first magnet and the second magnet, which can avoid short circuit problems caused by incorrect connection position between the connector 13 and the connection contact 52.

[0100] In the case mentioned in the foregoing embodiments, where the connector 13 is provided with a marker electrode 131 and a communication electrode 132, the connection contact 52 of the magnetic module 50 needs to be configured to match the marker electrode 131 and the communication electrode 132.

[0101] The introduction of the magnetic module 50 enables convenient and quick installation of the object module and the connector 13. Alternatively, a bayonet structure or other methods can be used to assemble the object module and the connector 13, ensuring a secure installation; however, these methods will not be elaborated upon here.

[0102] The acquisition device provided in this embodiment includes data transmission control: signals or data transmitted or received by the object module are input / output from the connector 13, and the data is processed and transmitted on the processing board 12. For example, audio data or signals received by the processing board 12 from the main control unit (such as a computer host, via USB interface, audio interface, or HDMI interface, etc.) are input to the speaker module for output using the communication electrode 132 of the connector 13 + USB protocol or other audio protocols. As another example, video images acquired by the light field camera module can be processed on the processing board 12 via the communication electrode 132 of the connector 13 using the MIPI CSI protocol. The synthesized image is then transmitted to the display device via the HDMI interface, or transmitted back to the main control unit via the USB interface for further processing, and then transmitted to the display device for display. This completes the data communication between the object module, processing board 12, main control unit, and display device.

[0103] In summary, the data acquisition device provided in this embodiment has the following characteristics:

[0104] 1) The receiving unit 20 in the acquisition device can be conveniently and quickly configured with various object modules to customize or switch different functions as needed, and the function can be corrected and the configuration content of the object modules can be modified according to the location of each object module. The object modules can be light field camera modules, speaker modules, microphone modules, infrared detection modules, etc. The light field camera module and microphone module can be used to acquire and process the 3D images and audio required for the light field display. The speaker module can also realize multi-point surround sound to enhance the stereo effect of the audio output of the display device, and the infrared detection module can realize spatial positioning function. Therefore, the acquisition device provided in this embodiment provides a universal interface or platform for the display device to freely disassemble different object modules, and can realize the free combination or switching of different functions.

[0105] 2) The fixed part 30, which is detachably connected to the display device, makes the entire acquisition device easy to disassemble. It can be detached from the display device when no additional functions are needed, ensuring the normal operation of the display device. At the same time, it can be quickly and conveniently assembled when needed. In addition, the acquisition device only needs to be connected to the external device by a single cable through the first and second communication interfaces for signal transmission. It can be used for external assembly on various display devices.

[0106] 3) By rotating the fixing part 30 and the receiving part 20, the position and posture of the object module can be easily adjusted, thereby improving the quality of signal acquisition or the quality of signal output.

[0107] 4) The introduction of the magnetic suction module 50 makes the installation of the object module and the connector 13 more convenient and quick, while avoiding the short circuit problem caused by poor alignment between the connector 13 and the object module.

[0108] Secondly, based on the same inventive concept, in another optional embodiment, a display device is provided, including the acquisition device provided in the first aspect embodiment. The display device can be a desktop computer monitor, an all-in-one computer monitor, or a laptop computer monitor, or a display product such as an LCD TV or an all-in-one conference machine. The beneficial effects of the display device are the same as those of the first aspect embodiment, and will not be repeated here.

[0109] Although preferred embodiments of this application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0110] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
