Description

Technical Field

[0001] This utility model relates to the field of camera adjustment technology, and in particular to a camera adjustment device for film and television production. Background Technology

[0002] In film and television production, cameras are crucial equipment, with different types suited to different shooting scenarios and needs. Common professional film and television cameras boast high resolution, capturing extremely delicate image details and presenting viewers with lifelike visual effects. For example, some high-end cameras can achieve 8K or even higher resolution shooting, clearly displaying both grand scenes and minute details. Their color reproduction is extremely high, accurately restoring the true colors of the subjects, resulting in natural, rich, and realistic color transitions, creating a unique visual style for the film.

[0003] Angle adjustment devices provide the camera with flexible shooting angles, greatly enriching the expressive power of film and television creation. Common angle adjustment devices include tripods and gimbals. Tripods provide stable support, ensuring the camera doesn't shake during shooting and guaranteeing image stability. Gimbals are divided into horizontal gimbals and omnidirectional gimbals. Horizontal gimbals allow the camera to rotate horizontally, facilitating panoramic shooting or tracking horizontally moving objects; omnidirectional gimbals allow the camera to rotate flexibly in multiple directions, including pitch, roll, and yaw, enabling diverse shooting angles such as low-angle, high-angle, and side shots, thus creating different visual effects.

[0004] There are also specialized camera cranes that use the extension and rotation of a robotic arm to allow cameras to shoot from different heights, distances, and angles, adding dynamism and grandeur to the film. For example, when shooting large scenes, a camera crane can shoot a panoramic view from above, then gradually zoom in for a close-up, creating a stunning visual experience. Furthermore, track devices combined with angle adjustment mechanisms allow the camera to move smoothly along the track while adjusting the angle, producing fluid and rhythmic shots. These are often used to track the movement of people or vehicles, providing viewers with an immersive viewing experience.

[0005] Currently, in film and television production, the common adjustment mechanism for camera control uses bolts to connect to the camera. However, due to the varying sizes, weights, and interface locations of different cameras, a single bolt connection lacks sufficient flexibility and adaptability. For larger or heavier cameras, a single bolt may not provide enough support and stability, leading to shaking during shooting and affecting the quality of the captured footage.

[0006] From an installation convenience perspective, using a single bolt to install on different cameras can be quite cumbersome. If the camera's interface position doesn't match the bolt hole, additional adapters or modifications to the camera itself may be required, increasing installation costs and potentially causing irreversible damage.

[0007] The single-bolt connection method also has limitations when adjusting the camera angle and position. To achieve the ideal shooting angle, precise fine-tuning of the camera is often required. However, with a single bolt, fine-tuning is difficult and may require repeated disassembly and reassembly of the bolt. This is not only time-consuming and laborious, but also prone to wear on the bolt during frequent operations, affecting the stability of the connection. Utility Model Content

[0008] The main objective of this invention is to provide a camera adjustment device for film and television production, which can effectively solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A camera adjustment device for film and television production includes a support base, a first servo motor, a connecting frame, and a connecting hole. The connecting hole is located on the end face of the connecting frame, and the first servo motor is installed at the connecting hole. The first servo motor is mounted on the support base and drives the connecting frame to rotate. The connecting frame is connected to side frames at both ends, and a crossbeam is connected between the two side frames. The end face of the crossbeam is provided with a first waist hole, and a first fastener is inserted into the first waist hole. The camera is installed through the first fastener and the two side frames, and the camera is rotated and its angle is changed by the first servo motor. The inner ends of the two side frames are connected to docking seats, and the outer end of one of the docking seats is connected to a second servo motor. The inner ends of the two docking seats are connected to fixed clamps through connecting pipes. Each fixed clamp has a movable clamp connected to its upper opening, and the inner end of the movable clamp is provided with a reset spring assembly, which is connected in the fixed clamp. The fixed clamp and movable clamp enable another way of installing the camera. The second servo motor enables the camera to rotate, further changing the angle.

[0010] In a further optional embodiment, the end faces of the fixed clamp and the movable clamp are provided with a second waist hole, and a second fastener is connected inside the second waist hole, thereby further fixing the camera inside the fixed clamp and the movable clamp. In a further alternative, the cross-sections of the first and second waist holes are elliptical, and the widths of the first and second waist holes are the same. The first and second fasteners include a fastening bolt, an elliptical washer, and an anti-slip washer. The anti-slip washer is placed on the elliptical washer, and the fastening bolt passes through the openings of the waist holes, the elliptical washer, and the anti-slip washer. In a further alternative, the cross-section of the connecting frame and the side frame is U-shaped, and the cross-section of the two side frames and the crossbeam is I-shaped. The connecting frame, the side frames and the crossbeam are fixed together by bolts, and anti-slip pads are provided at the connection points. A further alternative is that the first and second fasteners have the same specifications, that is, 1 / 4 inch or 3 / 8 inch, and have 20 or 16 threads per inch. In a further alternative, the cross-sections of the fixed clamp and the movable clamp are designed in an "L" shape, and the side view of the movable clamp is designed in a "U" shape. The two ends of the movable clamp pass through the upper opening of the fixed clamp and are connected to the reset spring assembly. In a further alternative, the reset spring assembly includes a spring portion and a plug. The spring portion is sleeved on both ends of the movable clamp and fixed to the movable clamp to achieve retraction when the movable clamp expands outward. The plug is connected to the fixed clamp by a thread to prevent the spring portion from falling off.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The first waist hole on the end face of the crossbeam is elliptical in shape. When it is fitted with the first fastener, the camera installation position can be adjusted within a certain range to meet different shooting needs, such as changes in the width of the shooting scene or different focus points, thus enhancing the flexibility of camera position adjustment.

[0012] Utilizing the elasticity of the return spring assembly, the movable clamp can firmly hold the camera, effectively preventing it from loosening or shifting even during shooting, thus ensuring the stability of the captured image. Both the fixed and movable clamps have second slotted holes on their ends, which, in conjunction with second fasteners, further secure the camera, ensuring its stability under various complex shooting actions and guaranteeing unaffected shooting quality.

[0013] The first servo motor performs initial adjustments to the camera angle, meeting basic shooting angle requirements. This allows the camera to quickly adjust to the approximate desired angle, such as horizontal left and right rotation, which can be used to shoot scenes from different angles, saving adjustment time and improving shooting efficiency. The second servo motor further alters the camera angle, achieving more precise angle adjustments to meet the needs of complex shooting scenarios. For example, when shooting close-ups or multi-angle switching shots, it can more accurately control the camera angle, resulting in richer and more professional footage, and improving the quality of film and television production.

[0014] Two mounting systems ensure the camera is securely mounted on the device. Both methods prevent loose mounting from affecting adjustment accuracy during angle adjustments, guaranteeing the angle adjustment mechanism can accurately adjust the camera's angle. The two mounting systems and two angle adjustment methods work together to fully meet the precise adjustment needs of camera angles and positions in film and television production. This makes the device more adaptable and professional in film and television production scenarios, contributing to the production of high-quality film and television content.
