We are sure that you have seen or heard about a Gimbal and have watched a video of it in action. The Gimbal is so levelheaded and smooth that you would think it has a mind or artificial intelligence. In this blog, We will be exploring the mysteries of How Does Gimbal Works? and why it is so incredible!
What are Gimbals?
Image Stabilization (IS), is a technique that reduces blurred photos by moving the camera lens automatically to compensate for camera shake and vibration during photography. Two common methods for image stabilization are:
- Software electronic (Electronic Image Stabilization – EIS)
- Optic image stabilization – OIS (hardware optical)
To improve image quality, electronic image stabilization employs a sophisticated software algorithm.
Optic image stabilization (or optical image stabilization) is a hardware solution that eliminates image blur due to camera shake or jitter while shooting. It is important to know that OIS doesn’t completely eliminate camera shake, but it does partially mitigate its effects. OIS won’t operate if the device shakes too much.
Electronic stabilization has the advantage that it requires only software to operate. OIS requires additional hardware components. Both image stabilization technologies can be used simultaneously.
It is common to believe that high-resolution cameras will produce a great image. Professionals can actually see that the cameras are attached securely to something, which prevents any sudden movements and shakes. Electronic stabilizers are the latest version of such a system for manual recording. These electronic stabilizers compensate for rotation due to the integrated electric motors.
How Does a Gimbal Work?
Blurring in photos can be caused by the shifting of the optical path between a focal length lens and the center sensor.
Adjusting the optical path of an image sensor to achieve the desired result by tilting or moving the lens to neutralize or compensate for the user’s movement can be done. There are two methods.
- The lens shift method was used previously. This is where the lenses within the cameras module are able to make small shifts. It does not allow for changing the optical path.
- The second, more modern method involves moving the entire module, including the image sensor, lens, and cameras This is how photo stabilization happens.
Optic image stabilization employs a variety of sensors to determine the offset along the coordinate axes X and Y. Sensors can also detect deviation and oblique displacement. All data is used to determine how big a shift in the lens position is necessary to ensure that the optical path is aligned with the center of an image sensor.
Although electronic image stabilization can achieve a similar result to analog, it isn’t enough for professional use due to its poor image quality.
Gimbals can use either EIS or OIS to fix these issues.
Two frames are used to connect any gimbal. The cameras and the handle are held by the frame. Three hinges powered by electric motors are located between the frames. Each electric motor stops the cameras from rotating on one of the three axes. A gimbal, also known as an “axis gimbal,” is a device that prevents the cam from rotating along with one of three axes. These three axes are often referred to as:
- Pitch – Up and Down movement
- Yaw – movement from side to side
- Roll – A circular movement that is either anticlockwise or clockwise.
Gimbals can also be equipped with gyroscopes that control the rotation of the cam around these axes.
Gimbals and all the features that come with them can stabilize your cams, prevent it from shaking, and produce a smooth recording and excellent photo quality.
All this proves that the electronic stabilizer, even in its most basic form, is a highly-tech device whose capabilities can only have been used for a lot more money in the past.
How Does Gimbal Work in Camera Stabilizer?
A gimbal is an essential component of a camera stabilizer, which helps to keep the camera steady and level while shooting videos or taking photos. The working mechanism of a gimbal in a camera stabilizer is based on the principles of a gyroscope.
A typical gimbal consists of three interconnected rings, with the innermost ring supporting the camera or other equipment. The outer rings are motorized and move independently of each other to compensate for any motion or vibration, keeping the camera level and steady.
The first ring in the gimbal is responsible for supporting the camera, while the other two rings are used for stabilization. The second ring is attached to the first ring through a set of motors and gears, which allow it to move horizontally and vertically.
The third ring is attached to the second ring and can move independently in the roll axis, allowing the camera to maintain its level orientation even if the device is tilted.
The gimbal may also feature sensors and electronic components that help detect and correct any unwanted motion. These sensors can include accelerometers, which measure the acceleration of the device, and gyroscopes, which measure the angular velocity. The electronic components use this information to adjust the motorized rings and keep the camera level and steady.
Do You Need a Gimbal?
Whether or not you need a gimbal depends on your specific needs and the type of footage you want to capture. If you’re looking to capture smooth and stable video footage, especially while walking, running, or moving in any way, then a gimbal may be an essential tool for you. A gimbal can help eliminate unwanted shaking or vibrations, resulting in more professional-looking footage.
However, if you mostly shoot still images or videos from a stationary position, a gimbal may not be necessary. In these cases, a tripod or other stabilizing equipment might be sufficient to keep the camera steady.
It’s also worth noting that gimbals can be expensive, especially high-quality ones that are designed for professional-grade cameras and equipment. If you’re just starting out in photography or videography, it might be more cost-effective to invest in other gear first, such as a tripod, before moving on to a gimbal.
Ultimately, the decision of whether or not to use a gimbal comes down to your individual needs and preferences. If you’re frequently shooting footage that requires a lot of movement, or you want to take your videography or photography to the next level, then a gimbal can be an excellent investment.
However, if you’re mostly shooting still images or videos from a stationary position, you may not need a gimbal, and other types of stabilizing equipment may suffice.
