Description

Technical Field

[0001] This utility model belongs to the field of camera technology, specifically relating to a camera component. Background Technology

[0002] With the rapid development of smart home technology, improving the visual experience of watching videos on display devices (such as TVs and monitors) has become a key research direction. To create an immersive viewing environment, the industry is experimenting with equipping display devices with ambient lighting, linking the viewing environment with the video content to enhance the video's impact and improve the user's visual experience.

[0003] Currently, there are many display devices or accessories on the market with ambient lighting functions, but the lighting effects of most existing ambient lights lack effective correlation with the video content. For example, when watching a cheerful video, the ambient light emits a dim light, which seriously affects the viewing experience.

[0004] To address this issue, the industry has proposed a solution of placing a camera on top of the display device. This solution uses the camera to capture the color information of the content being played in real time and outputs it to the ambient lighting control system, causing the ambient lights to emit light of the same color as the screen. Theoretically, this can achieve a certain degree of synchronization and improve the viewing experience.

[0005] However, in practical applications, this solution reveals significant flaws. Typically, only one or two cameras are used. When applied to ultra-large televisions, problems frequently arise. Due to the physical limitations of the camera's field of view, blind spots form at the four corners of the television screen. These blind spots act like "black holes" for information transmission, preventing the camera from capturing the screen content within these areas. This results in the ambient lighting control system being unable to obtain complete color information from the television screen, making it difficult, even with advanced control algorithms, to accurately emit light that matches the entire video frame.

[0006] Furthermore, in actual video viewing, the color distribution of the screen is complex and varied, with significant color differences between different areas. A single camera cannot cover the entire screen and can only capture color information from a portion of it. This means that the ambient light emitted can only reflect the colors of a localized area and cannot synchronize with the overall color changes of the video. For example, in a blind spot, if the upper half of the video frame is a bright blue sky and the lower half is lush green grass, a single camera may only capture a portion of the colors. The ambient light emitted will either appear bluish or greenish, failing to simultaneously represent the colors of both the blue sky and the grass, significantly diminishing the synchronization effect. This inaccurate lighting synchronization fails to create an immersive viewing environment and creates a sense of disconnect between the image and the lighting, ultimately failing to provide an ideal visual experience. Utility Model Content

[0007] The primary objective of this invention is to solve at least one of the aforementioned problems by providing a camera assembly.

[0008] To achieve the various objectives of this utility model, the following technical solution is adopted:

[0009] To achieve one of the purposes of this utility model, a camera assembly is provided, including a fixed base, an extension bracket, and a camera unit. The two ends of the extension bracket are respectively connected to the fixed base and the camera unit. The camera unit includes a main camera and two secondary cameras symmetrically arranged on both sides of the main camera. The optical axes of the secondary cameras are set at an angle to the optical axis of the main camera, and the horizontal fields of view of the three cameras partially overlap to form a continuous horizontal field of view coverage.

[0010] In one embodiment, the optical axes of the two secondary cameras are symmetrically arranged on both sides of the optical axis of the main camera, and the optical axis of the main camera and the optical axes of the two secondary cameras are on the same plane.

[0011] In one embodiment, the extension line of the optical axis of the main camera intersects the extension lines of the optical axes of the two secondary cameras at a single point.

[0012] In one embodiment, the optical axis of the main camera and the optical axis of the secondary camera are set at an acute angle.

[0013] In one embodiment, the camera unit further includes a lens housing with three lens slots, in which the main camera and the two secondary cameras are respectively disposed.

[0014] In one embodiment, the fixed base includes a control box, a base, and a limiting rotating member. The extension bracket is connected to the control box. The control box and the base rotate relative to each other via the limiting rotating member, and the limiting rotating member is used to constrain the rotation between the control box and the base, so that the control box and the base are set at an angle to form a clamping space.

[0015] In one embodiment, the control box is provided with a limiting hook, the limiting hook is located within the clamping space, and the limiting hook is disposed opposite to the base.

[0016] In one embodiment, the limiting rotating component includes a damping shaft, which is connected to both the control box and the base.

[0017] In one embodiment, the camera assembly further includes a flexible circuit board, and the control box contains a control circuit. The control circuit is electrically connected to the main camera and the two cameras respectively via the flexible circuit board, and the flexible circuit board is laid in the extension bracket.

[0018] In one embodiment, the extension bracket is a telescopic structure to adjust the distance between the camera unit and the fixed base.

[0019] Compared with existing technologies, this utility model has many advantages, including but not limited to:

[0020] This invention's camera assembly features a main camera and two secondary cameras symmetrically positioned on either side of it. The optical axes of the secondary cameras are deflected outwards relative to the main camera's optical axis. The horizontal fields of view of all three cameras partially overlap, creating a continuous horizontal field of view coverage. This allows the three cameras to capture images of the display screen area from different angles, complementing each other's capture range. Therefore, it can comprehensively capture images of all areas of the display screen, effectively avoiding the blind spots that may occur with traditional camera assemblies, and providing a more complete and accurate data foundation for subsequent image processing and applications.

[0021] Furthermore, the camera assembly of this invention employs a three-camera collaborative working method. The main camera is responsible for capturing images of the central area of ​​the display screen, while the symmetrically arranged secondary cameras on both sides extend the acquisition range to the sides respectively. Due to the outward deflection of the optical axes of the secondary cameras and the partial overlap of the horizontal fields of view of the three cameras, the horizontal field of view of the entire camera assembly is greatly expanded. This expansion is not merely a simple increase in range, but more importantly, it achieves continuous horizontal field of view coverage, enabling the acquisition of richer and more complete image information.

[0032] This utility model provides a camera component that is installed on the edge of a display screen. The camera component has good performance and can effectively capture images of various areas of the display screen without any blind spots.

[0033] To facilitate a clear explanation of this utility model, the description of the display screen will be used in conjunction with this embodiment. In this embodiment, it is recommended that the display screen be a television screen or a computer screen; however, it should be clarified that this recommendation should not be considered as a limitation on the scope of application of this utility model.

[0034] In a typical embodiment of this utility model, combined with Figure 1 and Figure 2The camera assembly 10 includes a fixed base 100, an extension bracket 200, and a camera unit 300. The extension bracket 200 is connected to the fixed base 100 and the camera unit 300 at both ends along its length.

[0035] Combination Figure 5 The fixed base 100 is securely mounted at the center of the top of the display screen 20. The extension bracket 200 is arranged to extend away from the display screen 20, and the extension direction of the extension bracket 200 is approximately perpendicular to the plane of the display screen 20. When the display screen 20 is playing images or videos, the camera unit 300 is used to capture the images or videos played on the display screen 20.

[0036] In this embodiment, the camera unit 300 specifically includes three cameras. (Combined with...) Figure 3 The three cameras are a main camera 310 and two secondary cameras. For ease of description, the two secondary cameras will be referred to as the first secondary camera 320 and the second secondary camera 330. The first secondary camera 320 and the second secondary camera 330 are arranged on both sides of the main camera 310 along the horizontal direction of the display screen 20, and are axially symmetrical with respect to the main camera 310.

[0037] In this embodiment, to clearly describe the optical axis characteristics of each camera, combined with Figure 6 The optical axis of the main camera 310 is defined as the main optical axis, the optical axis of the first secondary camera 320 is defined as the first optical axis, and the optical axis of the second secondary camera 330 is defined as the second optical axis.

[0038] Both the first and second optical axes are set at a certain angle to the main optical axis. Furthermore, the first and second optical axes are axially symmetrical with respect to the main optical axis. Specifically, in this embodiment, the main optical axis, the first optical axis, and the second optical axis are all located on the same plane (for ease of subsequent description, this plane is defined as the first plane). Further, the first plane is approximately parallel to the plane where the display screen 20 is located. This arrangement helps the camera to perform more accurate and comprehensive image acquisition of the relevant area of ​​the display screen 20.

[0039] From an angular perspective, both the first and second optical axes form acute angles with the principal optical axis. In this embodiment, to optimize image acquisition, it is recommended that both the first and second optical axes be set at a 60° angle with the principal optical axis. However, it should be noted that this angle setting is only a preferred option and should not be considered a limitation on the scope of protection of this utility model. In practical applications, this angle can be reasonably adjusted according to specific needs and design requirements.

[0040] A camera's field of view is an important characteristic, referring to the range of spatial angles it can capture, typically expressed as horizontal, vertical, or diagonal angles. In this invention, because the first optical axis of the first auxiliary camera 320 is set at a predetermined angle to the principal optical axis of the main camera 310, and both are located on a first plane, a predetermined field of view distribution effect is achieved. Specifically, the vertical field of view of the main camera 310 overlaps with the vertical field of view of the first auxiliary camera 320. This overlap helps ensure the continuity and integrity of image acquisition in the vertical direction.

[0041] Meanwhile, the horizontal field of view of the first secondary camera 320 is further away from the main optical axis than that of the main camera 310, and the horizontal field of view of the first secondary camera 320 and the main camera 310 also partially overlap. This partial overlap of the horizontal field of view achieves continuous horizontal field of view coverage, effectively expanding the angular range of the horizontal field of view of the camera unit 300. As a result, the camera assembly 10 can better capture images of the display screen 20 in the horizontal direction, avoiding blind spots during image acquisition, significantly improving the image acquisition performance of the camera assembly 10, and providing a strong guarantee for obtaining high-quality and comprehensive image information.

[0042] Similarly, the second optical axis of the second auxiliary camera 330 is also set at a predetermined angle to the principal optical axis of the main camera 310. The first and second optical axes are symmetrically arranged about the principal optical axis. This predetermined angle and symmetrical arrangement result in the horizontal field of view of the second auxiliary camera 330 and the main camera 310 overlapping. Specifically, this overlap further expands the horizontal field of view of the camera unit 300, providing a structural basis for more comprehensive image information acquisition.

[0043] Furthermore, regarding the specific distribution of the horizontal field of view, the horizontal field of view of the first secondary camera 320 and the horizontal field of view of the second secondary camera 330 are respectively positioned on both sides of the horizontal field of view of the main camera 310 along the horizontal direction of the display screen 20, so that the horizontal field of view of the first secondary camera 320, the horizontal field of view of the main camera 310, and the horizontal field of view of the second secondary camera 330 overlap sequentially. This sequentially overlapping field of view distribution forms a continuous and seamless horizontal field of view.

[0044] Specifically, in the horizontal direction, the first secondary camera 320 first covers a certain area with its horizontal field of view, then partially overlaps with the horizontal field of view of the main camera 310, ensuring that there are no blank areas in image acquisition at the boundary between the two. Then, the horizontal field of view of the main camera 310 continues to extend, partially overlapping with the horizontal field of view of the second secondary camera 330, similarly avoiding blind spots at the boundary. Through this sequential overlap of three layers of field of view, the horizontal field of view range of the camera unit 300 is effectively expanded.

[0045] The significant effect of this design is that the camera unit 300 can capture images of various areas of the display screen 20 in the horizontal direction. Regardless of the image's position on the horizontal surface of the display screen 20, it can be captured by at least one camera in the camera unit 300, thus avoiding blind spots during image acquisition and greatly improving the horizontal image acquisition performance of the camera unit 300. This provides a reliable guarantee for obtaining complete and accurate horizontal image information of the display screen 20.

[0046] In one embodiment, based on a comprehensive consideration of the overall image acquisition effect and structural coordination of the camera unit 300, the main optical axis of the main camera 310, the first optical axis of the first secondary camera 320, and the second optical axis of the second secondary camera 330 are arranged in a preset manner. Specifically, the virtual extension lines of the main optical axis of the main camera 310, the virtual extension lines of the first optical axis of the first secondary camera 320, and the virtual extension lines of the second optical axis of the second secondary camera 330 intersect at the same point in the space above the plane where the display screen 20 is located.

[0047] Regarding the vertical field of view, the intersecting virtual extensions of the three optical axes allow the main camera 310, the first secondary camera 320, and the second secondary camera 330 to coordinate and work together in the vertical direction. The main camera 310 provides the basic coverage of the vertical field of view, while the first secondary camera 320 and the second secondary camera 330 supplement and extend it on both sides. Through this synergy, the vertical fields of view of the three cameras can be seamlessly connected to form a unified and complete vertical field of view. This means that in the vertical direction, regardless of the height of the target object above the display screen 20, it can be covered by the vertical field of view of at least one camera, thus avoiding image acquisition blind spots caused by discontinuities in the vertical field of view.

[0048] Regarding the horizontal field of view, the design also benefits from the convergence of three virtual optical axes. The main camera 310's horizontal field of view serves as the core coverage area, while the first and second secondary cameras 320 extend horizontally to the sides. Due to the symmetry and intersection of the optical axes, the horizontal fields of view of the first and second secondary cameras 320 and 330 can overlap reasonably with the main camera 310's horizontal field of view on both sides. This overlap not only ensures the continuity of the horizontal field of view but also further expands its overall range. In the horizontal direction, regardless of whether the target object is located on the left, right, or center of the display screen 20, it can be captured by the cameras in the camera unit 300, eliminating any blind spots in horizontal image acquisition.

[0049] Therefore, by making the virtual extension lines of the main optical axis of the main camera 310, the virtual extension lines of the first optical axis of the first secondary camera 320, and the virtual extension lines of the second optical axis of the second secondary camera 330 intersect at a single point on the display screen 20, a high degree of uniformity in image acquisition is achieved among the main camera 310, the first secondary camera 320, and the second secondary camera 330. Together, they form a unified vertical and horizontal field of view, effectively avoiding blind spots that may occur during image acquisition, significantly improving the image acquisition performance of the camera unit 300, and providing a solid technical guarantee for obtaining high-quality, comprehensive image information.

[0050] In a typical embodiment of this utility model, combined with Figure 3 and Figure 4The camera unit 300 also includes a lens housing 340, which has three lens slots 341. The main camera 310, the first secondary camera 320, and the second secondary camera 330 are respectively installed in the three lens slots 341 to limit the position of the three cameras and improve the structural stability of the camera assembly 10. In actual use, the camera assembly 10 may be subjected to various external forces, such as vibration and collision. The limiting effect of the lens slots 341 on the cameras can effectively resist the influence of these external forces, avoiding problems such as inaccurate image acquisition and image shaking caused by camera loosening, and providing a solid structural guarantee for the stable and reliable operation of the camera assembly 10.

[0051] The fixed base 100 includes a control box 110, a base 120, and a limiting connector. Among these, combined with... Figure 1 and Figure 2 The control box 110 and the base 120 are assembled by a rotatable connection, meaning that the two can rotate around the connection point at a certain angle.

[0052] A limiting connector is provided at the junction of the control box 110 and the base 120. This limiting connector has a dual function: firstly, it constrains the relative rotation of the control box 110 and the base 120 by increasing the rotational resistance between them through its structural characteristics. Thus, under normal use, rotating the control box 110 and / or the base 120 requires an external force of a certain strength and direction, effectively preventing the control box 110 and the base 120 from rotating freely due to accidental contact or slight external force, thereby ensuring structural stability.

[0053] When the control box 110 and the base 120 rotate relative to each other, an angle is formed between them. Under the precise constraint and limiting effect of the limiting connector, this angle can be maintained within a stable range and will not change arbitrarily due to external interference. Based on this characteristic, a stable clamping space is formed between the control box 110 and the base 120. The fixed base 100 is stably mounted on the edge 21 of the monitor through this carefully designed clamping space.

[0054] During specific installation, in conjunction with Figure 1 , Figure 2 and Figure 5The fixed base 100 is securely positioned on the edge 21 of the display using the clamping space. At this time, the control box 110 and the base 120 are located on opposite sides of the edge 21 of the display, with the control box 110 tightly abutting against the first side wall 211 of the edge 21 and the base 120 tightly abutting against the second side wall of the edge 21. Under the continuous constraint of the limiting connector, the control box 110 and the base 120 are firmly fixed and will not rotate freely without external force, thereby ensuring that the clamping space formed by the control box 110 and the base 120 can be stably set on the edge 21 of the display, providing a reliable mounting base for the entire camera assembly 10.

[0055] Furthermore, the control box 110 is also provided with a limiting hook 115. This limiting hook 115 is disposed opposite to the base 120 and is used to hook onto the third sidewall 212 of the edge 21 of the display. The second sidewall is disposed opposite to the third sidewall 212, and the first sidewall 211 is connected to both the second sidewall and the third sidewall 212. The tight fit between the limiting hook 115 and the third sidewall 212 further enhances the connection stability between the control box 110 and the edge 21 of the display, effectively preventing the control box 110 from loosening or falling off after installation.

[0056] Meanwhile, the base 120 is tightly pressed against the second sidewall of the edge 21 of the display, and the base 120 is specially equipped with a counterweight. The counterweight is rationally configured and installed according to actual needs and mechanical principles. Under the action of the counterweight, the base 120 can generate sufficient supporting force to support the control box 110, the extension bracket 200, and the camera unit 300, which are located on the first sidewall 211 of the edge 21 of the display. In this way, even if these components have a certain weight, they will not tip over towards the base 120 due to gravity, thereby ensuring the stability and safety of the entire camera assembly 10 after installation and providing a strong guarantee for the normal operation of the camera assembly 10.

[0057] Combination Figure 1 and Figure 2The limiting connector includes a damping shaft 130. This damping shaft 130 consists of a threaded portion and a threaded hole portion. The threaded portion fits into a pre-set shaft hole in the base 120 for initial positioning. The threaded hole portion has multiple first threaded holes, and correspondingly, the control box 110 has second threaded holes. Through the threaded connection of the first and second threaded holes, the damping shaft 130 securely connects the control box 110 and the base 120. This damping shaft 130 possesses unique damping characteristics, effectively constraining the control box 110 and the base 120 to rotate around it. Without external force, relative rotation between the two is difficult, thus ensuring the stability of the clamping space formed by the control box 110 and the base 120. This design allows the fixed base 100 to be reliably mounted on the edge 21 of the display, providing stable support for the camera assembly 10.

[0058] In another embodiment, the limiting connector is composed of a rotating shaft (not shown) and a torsion spring (not shown). The control box 110 has a first rotating hole, and the base 120 has a corresponding second rotating hole, with their positions aligned. The rotating shaft passes through the first and second rotating holes, enabling a rotatable connection between the control box 110 and the base 120. Simultaneously, the torsion spring is mounted on the rotating shaft, and its elastic force acts between the control box 110 and the base 120. When the control box 110 and the base 120 rotate relative to each other, the torsion spring undergoes corresponding elastic deformation, providing a restoring force. This ensures that, without continuous external force, the control box 110 and the base 120 maintain a relatively stable positional relationship, thereby maintaining the stability of the clamping space and facilitating the installation and use of the fixing base 100 on the edge 21 of the display.

[0059] The control box 110 contains a control circuit, which serves as the control core of the camera unit 300. It is electrically connected to the camera unit 300 via a connecting cable 114, thereby enabling control over various operations of the camera unit 300. In this embodiment, combined with... Figure 4 The control circuit is integrated on a single circuit board 111.

[0060] Combination Figure 3 and Figure 4 The control box 110 consists of two parts: a box body 112 and a cover 113. The cover 113 and the box body 112 are connected by a snap-fit ​​mechanism, which ensures a stable and reliable connection between them. When the cover 113 and the box body 112 are snapped together, a accommodating space (referred to as the first accommodating space) is formed between them to accommodate related components, and the circuit board 111 is disposed within this first accommodating space.

[0061] The control circuit is connected to the camera unit 300 via connecting cable 114. Its function is not only to provide the camera unit 300 with the power required for operation, but also to realize the signal transmission and reception function. Connecting cable 114 is laid along the extension bracket 200, extending from the control box 110 to the camera unit 300, to ensure stable transmission of signals and power.

[0062] Specifically, the connecting cable 114 takes the form of a flexible circuit board 111, with both ends of the flexible circuit board 111 electrically connected to the circuit board 111 and the three cameras of the camera unit 300, respectively. The flexible circuit board 111 is equipped with signal lines and power lines. The two ends of the signal lines are connected to the control circuit and the camera unit 300, respectively. Their main function is to realize signal transmission between the control circuit and the camera unit 300, ensuring that the camera unit 300 can operate according to the instructions of the control circuit and accurately feed back the acquired image and other information to the control circuit. Similarly, the two ends of the power lines are connected to the control circuit and the camera unit 300, respectively. Their function is to enable the control circuit to provide stable power to the camera unit 300 through the power lines, ensuring the normal operation of the camera unit 300. In this embodiment, the signal lines and power lines are printed on the flexible circuit board 111 using a printing process. This design helps to improve the stability and reliability of the circuit.

[0063] The extension bracket 200 consists of an upper shell 221 and a lower shell 222, which together form a complete extension bracket 200 structure. Inside the extension bracket 200, a receiving space (referred to as the second receiving space) is formed. The connecting cable 114 is laid within this second receiving space, which constrains and protects the connecting cable 114, preventing it from moving freely or being damaged by external forces within the extension bracket 200. In one embodiment, the upper shell 221 is integrally formed with the cover 113, and the lower shell 222 is integrally formed with the box body 112.

[0064] In one embodiment, the extension bracket 200 is a telescopic structure, which allows for precise adjustment of the spatial distance between the camera unit 300 and the fixed base 100 by flexibly adjusting the length of the extension bracket 200. Since the field of view of the camera unit 300 is closely related to its relative position to the fixed base 100, this distance adjustment allows for effective adjustment of the field of view of the camera unit 300, meeting diverse needs for image acquisition range and angle in different application scenarios.

[0065] Specifically, in this embodiment, it is recommended that the extension bracket 200 be composed of multiple sliding pieces connected in sequence. Adjacent sliding pieces are connected by a special sliding structure, such as the cooperation of a sliding groove and a sliding rail, to achieve a tight and flexible sliding connection.

[0066] During actual adjustment, users can adjust the sliding distance between multiple sliding plates according to their actual needs. Increasing the sliding distance between the sliding plates increases the overall length of the extension bracket 200, correspondingly increasing the distance between the camera unit 300 and the fixed base 100, thus expanding the field of view of the camera unit 300. Conversely, decreasing the sliding distance between the sliding plates shortens the extension bracket 200, reducing the distance between the camera unit 300 and the fixed base 100, and consequently shrinking the field of view of the camera unit 300. This adjustment method is simple to operate, highly accurate, and effectively meets the requirements for adjusting the field of view of the camera unit 300 in different scenarios.

[0067] In summary, the camera assembly of this invention, through the coordinated operation of three cameras, can comprehensively capture images from all areas of the display screen, effectively avoiding the blind spot problem that may occur with traditional camera assemblies. Compared to single-camera or dual-camera solutions, it greatly expands the image acquisition range and can obtain richer and more complete image information.
