[0036] The following will combine the accompanying drawings and, through specific embodiments and their application scenarios, elaborate in detail on the multimedia information acquisition device and display terminal provided in the embodiments of the present application that are built into the display terminal.

[0037] As Figures 1 to 7 shown, according to some embodiments of the present application, the multimedia information acquisition device built into the display terminal is applied to the display terminal. The display terminal includes a fixed bracket 10 and a display 20, and the display 20 is installed on the fixed bracket 10; the multimedia information acquisition device includes a tray 30 and a camera 40. The tray 30 is installed on the fixed bracket 10 and is located below the display 20. A preset area 301 for placing the object to be photographed is provided on one side of the tray 30 facing the display 20; the camera 40 is installed at the bottom of the display 20. The camera 40 includes a camera 41, and the orthographic projection of the camera 41 in the vertical direction is offset from the center of the preset area 301; the camera 40 is electrically connected to the display 20 and is used to photograph the preset area 301 and display the photographed information through the display 20. Among them, the photographed information includes but is not limited to multimedia information such as video and images.

[0038] In the embodiments of the present application, by installing the display 20 and the tray 30 on the fixed bracket 10, the tray 30 is located below the display 20, and a preset area 301 is set on one side of the tray 30 facing the display 20 to place the object to be photographed. Furthermore, a camera 40 is provided at the bottom of the display 20. The camera 41 in the camera 40 can photograph the object to be photographed in the preset area 301 and generate photographed information, and the photographed information can be displayed through the display 20. Moreover, the orthographic projection of the camera 41 in the vertical direction is offset from the center of the preset area 301, that is, the camera 41 photographs from the upper side of the preset area 301. In this way, the limitation of the installation position between the preset area 301 and the camera 41 can be reduced. In addition, in the present application, by integrating the camera 40 into the display 20, it is not only convenient for actual use but also can improve the overall aesthetics of the display terminal.

[0039] It can be understood that the camera 40 is an instrument that can collect and process and generate multimedia information such as video, images, and audio, and is widely used in various industries, such as enterprise offices, education and other fields. Furthermore, by electrically connecting the camera 40 to the display 20, the multimedia information output by the camera 40 can be transmitted to the display 20 for display.

[0040] Traditional cameras 40 are usually used alone. In actual applications, an external display device needs to be connected. Various cables are required to achieve the electrical connection between the camera 40 and the power supply and the display device. Not only is the operation relatively cumbersome, but also the cables used for connection need to occupy space and appear messy and unattractive.

[0041] In a display device, the display screen is generally at a certain height from the ground or the workbench, and there will be a certain amount of empty space at the bottom of the display screen, resulting in waste of space. Therefore, in this application, the camera 40 is cleverly integrated into the bottom of the display 20, so that the empty space at the bottom of the display 20 can be fully utilized, and there is no need to occupy additional space to set up the camera 40.

[0042] Moreover, the camera 40 can be directly electrically connected to the display 20, and then the operation of the camera 40 can be directly controlled through the display 20 without connecting cables anymore. This can not only simplify the connection operation and facilitate actual use, but also reduce the space occupied by the overall display terminal and improve the overall aesthetics.

[0043] It should be noted that when the camera 41 of a traditional camera is in use, it is necessary to make the camera 41 directly above the object to be photographed, make the center point of the camera 41 coincide with the center point of the object to be photographed, and the camera 41 is aligned with the center point of the object to be photographed for shooting. For this kind of camera structure, the setting position of the camera 41 is restricted by the placement position of the object to be photographed. In order to make the shooting range of the camera 41 larger, it is necessary to increase the size of the support structure of the camera 41, resulting in an increase in the volume of the device.

[0044] In this application, the camera 40 is set at the bottom of the display 20, and the orthogonal projection of the camera 41 in the vertical direction is offset from the center of the preset area 301 in the tray 30, that is, the camera 40 shoots from the upper side of the preset area 301. In this way, the position restriction between the preset area 301 and the camera 41 is reduced, facilitating the flexible design and layout of the overall structure of the terminal device.

[0045] In some embodiments, an audio acquisition unit can also be provided in the camera 40 for acquiring an audio signal, so as to transmit the audio signal to the display and play the corresponding audio signal by the display.

[0046] In some embodiments, the tray 30 can adopt a flat plate structure, and a certain area is reserved on the upper surface of the tray 30 for placing the object to be photographed. Among them, the shape and size of the preset area 301 can be flexibly set according to actual needs, and this application does not make any limitations here.

[0047] In some other embodiments, the included angle α between the optical axis of the camera 41 and the plane where the preset area 301 is located satisfies: 0° < α ≤ 90°. For example, the included angle α can be set to: 15°, 30°, 45°, 60°, 75°, 90°, etc. Among them, the optical axis refers to the central axis of the optical system in the camera 41.

[0048] Optionally, as Figures 3 to 5As shown, the optical axis of the camera 41 is perpendicular to the plane where the preset area 301 is located.

[0049] In the embodiment of the present application, by setting the optical axis of the camera 41 to be perpendicular to the plane where the preset area 301 is located, the camera 41 shoots vertically downward from the upper side of the object being photographed, thereby achieving oblique imaging of the object being photographed. Since the camera 41 shoots vertically downward, the photographed object will not be distorted, and there is no need to lower the resolution for correction when processing the captured image, thereby ensuring the clarity of the image. At the same time, the optical axis of the camera 41 is staggered from the center of the preset area 301, thereby reducing the position restriction between the preset area 301 and the camera 41, and facilitating the flexible design layout of the overall structure of the terminal device.

[0050] It can be understood that when using the camera 41 to tilt the object, if the optical axis of the camera 41 is at a certain tilt angle, the initial image information obtained is a tilted image, and the object in the image will be distorted to a certain extent. The initial image needs to be corrected subsequently. During the initial image correction process, the overall resolution of the image needs to be reduced to correct the tilted image into a normal flat image, so that the clarity of the final image will be reduced.

[0051] In the present application, the optical axis of the camera 41 is made perpendicular to the plane where the preset area 301 is located, so that no distortion will occur in the captured image. Furthermore, the resolution does not need to be reduced when processing the captured image, thereby ensuring the clarity of the image.

[0052] Alternatively, if Figure 4 As shown, the tray 30 is movably connected to the fixed bracket 10, and the fixed bracket 10 is provided with a accommodating space 101 at a position corresponding to the tray 30. The tray 30 has a stored state and an expanded state; wherein, in the expanded state, the tray 30 at least partially extends out of the fixed bracket 10, and the orthographic projection of the camera 41 along the vertical direction is offset from the center of the preset area 301 on the tray 30; in the stored state, the tray 30 is stored in the accommodating space 101.

[0053] In the embodiment of the present application, the tray 30 is movably connected to the fixed bracket 10 so that the position of the tray 30 can be flexibly adjusted. When not in use, the tray 30 can be stored in the accommodating space 101, thereby reducing the space occupied by the entire display terminal; at the same time, it also prevents the tray 30 from always being in an extended state, which may easily cause safety hazards.

[0054] In some embodiments, one end of the tray 30 can be rotatably connected to the fixed bracket 10, and the other end of the tray 30 extends in a direction away from the fixed bracket 10. The position of the tray 30 can be adjusted by rotating the tray 30.

[0055] Of course, other movable connection methods can also be adopted between the tray 30 and the fixed bracket 10, such as telescopic connection, sliding connection, detachable connection, etc., which can be flexibly set according to actual needs and will not be limited here.

[0056] Optionally, as Figure 2 and Figure 4 shown, the display 20 includes a display body 21 and a display screen 22. The display screen 22 is arranged in the display body 21, and one side of the display body 21 facing away from the display screen 22 is mounted on the fixed bracket 10; in the unfolded state, the tray 30 extends from the side of the display body 21 facing away from the display screen 22 towards the display screen 22 (i.e., Figure 2 the X direction in

[0057] In the embodiment of the present application, by setting the tray 30 to extend from the side of the display body 21 facing away from the display screen 22 towards the display screen 22 in the unfolded state, the object to be photographed can be displayed and photographed on the front of the display 20, which is convenient for actual use.

[0058] It can be understood that by setting the tray 30 to extend from the side of the display body 21 facing away from the display screen 22 towards the display screen 22 in the unfolded state, the preset area 301 in the tray 30 is located in front of the display screen 22, which is convenient for placing and displaying the object to be photographed. At the same time, the structure on the back of the display terminal can also be reduced, which is convenient for the installation and placement of the display terminal.

[0059] In some embodiments, the positive projection of the display 20 in the vertical direction is offset from the center of the preset area 301. During the use of the display terminal, ambient light irradiates the preset area 301 in the tray 30 from above the tray 30. With the structural setting of the present application, the shielding of the light irradiated on the preset area 301 by the display 20 can be reduced.

[0060] Optionally, as Figure 4 shown, the display terminal further includes a locking structure 11. The locking structure 11 is arranged between one end of the tray 30 close to the fixed bracket 10 and the fixed bracket 10, and the locking structure 11 is used for locking or unlocking between the tray 30 and the fixed bracket 10.

[0061] In the embodiment of the present application, by arranging the locking structure 11 between one end of the tray 30 close to the fixed bracket 10 and the fixed bracket 10, the position of the tray 30 can be locked to avoid the displacement of the tray 30 during use and affecting the shooting effect.

[0062] In some embodiments, the locking structure 11 may include a locking rod and a lock buckle. The lock buckle may be arranged at one end of the tray 30 close to the fixed bracket 10. One end of the locking rod is rotatably connected to the fixed bracket 10, and the other end is provided with a lock hole adapted to the lock buckle structure. When the tray 30 is in the unfolded state, the locking rod may be rotated so that the lock hole on the locking rod engages with the lock buckle in the tray 30 to achieve locking of the position of the tray 30. When the tray 30 needs to be folded, the locking hole of the locking rod and the lock buckle are released to release the locking of the tray 30.

[0063] Of course, the locking structure 11 may also adopt other structures, as long as it can achieve locking and unlocking between the tray 30 and the fixed bracket 10, and can be flexibly set according to actual needs, and the embodiment of the present application is not limited here.

[0064] Alternatively, if Figure 5 and Figure 7 As shown, the camera 40 further includes a fill light 42 , which is used to irradiate light to the preset area 301 for fill light, and the light emitted by the fill light 42 is reflected by the preset area 301 to form a reflected light that avoids the camera 41 .

[0065] In the embodiment of the present application, a fill light 42 is provided in the camera 40, so as to use the fill light 42 to fill light the preset area 301. In addition, by setting the relative position of the camera 41 and the fill light 42, the reflected light formed by the light emitted by the fill light 42 after being reflected by the photographed object does not pass through the camera 41, thereby preventing the light of the fill light 42 from entering the camera 41 after being reflected by the surface of the photographed object, thereby preventing the light from the fill light 42 from entering the camera 41 and causing a light spot in the captured image, which helps to improve the clarity and image quality of the captured image.

[0066] Alternatively, if Figure 7 As shown, there are at least two fill lights 42, and at least two fill lights 42 are respectively arranged on both sides of the camera 41. By respectively arranging fill lights 42 on both sides of the camera 41 in the camera 40, the fill light effect can be improved through the common fill light effect of multiple fill lights 42, and the uneven distribution of fill light effects at different positions of the preset area 301 can be avoided.

[0067] At the same time, in the embodiment of the present application, the fill light 42 and the camera 41 are located on the same side of the preset area 301, which can avoid the problem of light spots appearing in the captured image due to the light of the fill light 42 entering the camera 41 after being reflected on the surface of the photographed object.

[0068] In some embodiments, the fill light 42 is an LED light. By setting the fill light 42 as an LED light, the fill light effect of the fill light 42 can be improved, and the use cost of the fill light 42 can be reduced, thereby reducing the overall cost of the display terminal.

[0069] Specifically, the supplementary light 42 may include a light source and a lens. An installation groove is provided in the housing 43 of the imager 40. The light source is installed in the installation groove, and the lens covers the notch of the installation groove. The light emitted by the light source is evenly irradiated onto the preset area 301 in the tray 30 after being refracted by the lens, thereby achieving uniform illumination of the preset area 301.

[0070] Optionally, as Figure 5 and Figure 7 shown, the imager 40 further includes a housing 43 and an electrical connection line (not shown in the figure). The display 20 includes an electronic control module. The camera 41 is installed in the housing 43, and the camera 41 is electrically connected to the electronic control module in the display 20 through the electrical connection line. The housing 43 and the display 20 enclose a receiving cavity, and the electrical connection line is received in the receiving cavity.

[0071] In the embodiment of the present application, the camera 41 is electrically connected to the electronic control module of the display 20 through the electrical connection line, so that the electronic control module of the display 20 can control the camera 41 simultaneously, realizing the integrated function of the camera 41 and the display 20. At the same time, a receiving cavity is formed between the housing 43 of the imager 40 and the display 20, and the electrical connection line is received in the receiving cavity, which can improve the overall aesthetic appearance of the display terminal.

[0072] Optionally, a receiving groove is provided on one side of the display 20 close to the tray 30. The imager 40 is movably connected to the receiving groove, and the imager 40 can move relative to the display 20 so that the imager 40 can be received into or extended out of the receiving groove.

[0073] In the embodiment of the present application, by providing a receiving groove on one side of the display 20 close to the tray 30, the imager 40 is movably connected to the receiving groove. Furthermore, the position of the imager 40 can be flexibly adjusted according to actual use needs. When in use, by moving the imager 40 to extend it out of the receiving groove, a shooting operation can be performed, and when not in use, the imager 40 can be received into the receiving groove to form a shielding protection for the imager 40.

[0074] In some embodiments, the imager 40 can be slidably connected to the display 20. By sliding the imager 40, the position of the imager 40 relative to the receiving groove can be adjusted, so as to adjust the imager 40 to be received into or extended out of the receiving groove according to needs.

[0075] Of course, other movable connection methods can also be adopted between the imager 40 and the display 20 to adjust the position of the imager 40 relative to the receiving groove, so that the imager 40 can be received into or extended out of the receiving groove. Those skilled in the art can flexibly set according to actual needs, and the embodiments of the present application do not make limitations here.

[0076] In some embodiments, asFigure 7 As shown, the imaging device 40 is provided with a connection port 44. The connection port 44 is electrically connected to the camera 41, and the connection port 44 is used to connect electrical components. By providing the connection port 44 in the imaging device 40 and electrically connecting the connection port 44 to the camera 41, electrical components can be externally connected using the connection port 44, thereby meeting the application requirements of different scenarios.

[0077] In some embodiments, the camera 41 is a wide-angle camera. By setting the camera 41 as a wide-angle camera, the viewing and shooting range of the camera 41 can be increased, thereby improving the shooting effect of the camera 41.

[0078] Optionally, as Figure 1 shown, an embodiment of the present application further provides a display terminal, including a fixed bracket 10, a display 20, and the multimedia information acquisition device in the above embodiment; the multimedia information acquisition device includes a tray 30 and an imaging device 40. The tray 30 is mounted on the fixed bracket 10 and is located below the display 20. The display 20 is mounted on the fixed bracket 10, and the imaging device 40 is mounted at the bottom of the display 20; the imaging device 40 is electrically connected to the display 20 and is used to shoot a preset area 301 in the tray 30 and display the shooting information through the display 20.

[0079] In the embodiment of the present application, by mounting the display 20 and the tray 30 on the fixed bracket 10, the tray 30 is located below the display 20, and a preset area 301 is provided on the side of the tray 30 facing the display 20 for placing the object to be shot. Furthermore, an imaging device 40 is provided at the bottom of the display 20. The camera 41 in the imaging device 40 can shoot the object to be shot in the preset area 301 and generate shooting information, and the shooting information can be displayed through the display 20. Moreover, the orthographic projection of the camera 41 in the vertical direction is offset from the center of the preset area 301, that is, the camera 41 shoots from the upper side of the preset area 301. In this way, the limitation on the setting position between the preset area 301 and the camera 41 can be reduced. In addition, by integrating the imaging device 40 into the display 20 in the present application, it is not only convenient for actual use but also improves the overall aesthetics of the display terminal.
