Most camera smartphones feature optical image stabilization (OIS) technology, which adjusts mechanical components of the camera lens to help suppress the image artifacts and blur that occur when a user’s hand shakes while shooting video. The lens is suspended in the middle of a module by several springs and electromagnets that move the lens to compensate for movement. This electromechanical solution keeps the camera steady – which is the key to producing smooth, stable videography.
While this works well for some applications, it often struggles to keep pace when a user is walking, running, or moving the smartphone camera quickly. Scenery shot during a hike, sports action captured along the sidelines, or the ocean view when perched on the bow of a moving boat usually winds up looking blurry and distorted. It’s simply too difficult to keep subjects in frame despite the OIS technology’s best attempts to work around the shake.
Vidhance Removes Unwanted Movement from Fast-Paced Recordings
Here’s where Imint’s Vidhance Video Stabilization technology comes in. The software works alongside a smartphone camera’s OIS to frame by frame electronically cancel unwanted movement caused when a user unintentionally sways, wobbles or shakes as they hold the phone. Doing so renders recordings that are noticeably more professional, clearer, and free of jitter. Vidhance software eradicates videography issues by applying electronic image stabilization techniques (EIS) to OIS. By allowing OIS and EIS to work together, the smartphone cameras produce better quality images than by utilizing either technology alone.
Fusing the Forces of OIS and EIS Technologies
Vidhance Video Stabilization technology turns mediocre results due to camera movement into enjoyable, true-to-life recordings by fusing OIS and EIS together. This fused method of video stabilization combines a host of advanced algorithms, artificial intelligence, and signal processing to overcome camera shake and dramatically improve the recorded video.
The Vidhance software first estimates the camera motion by extracting elements of the OIS movements and other motion sensors. It then predicts the user’s intention of movement. The last step models and removes distortion and synthesizes new, improved video by transforming each frame. This three-step process is effective enough to operate in all video modes, including 60fps and 4K.
That said, not all camera bumps, shakes, and sweeps are bad – and Vidhance technology can intelligently sense the difference. While the technology removes unwanted motion from captured smartphone video, it leaves behind the desired motion, while smoothing out the video that remains. The result is professional-looking content that appears exactly as the video creator intended, even when the user is moving rapidly.
These advanced stabilization techniques enable the smartphone camera to adapt to the environment and the user, self-adjusting to create the best possible image with less cropping and buffer around the edge of the image. The entire process happens automatically, unbeknownst to the person shooting the video. All they see is clearer, smoother video that’s a true representation of the environment. With Vidhance, users get the best of both videography worlds: the ability to move freely while shooting face-paced environments without sacrificing image quality.
The Scores Speak for Themselves
Assessing video quality is a highly subjective practice; yet there are some objective benchmarks to give smartphone manufacturers a good indication of a video stabilization technology’s capabilities. Time and time again, Vidhance Video Stabilization technology has received some of the highest scores on the scientific videography protocol DxOMark. Using industry-grade lab tools, DxOMark puts smartphone brands enabled by Vidhance at the top of its smartphone camera rankings for video stabilization.
Additionally, Imint has designed a new Video Stabilization Comparison and Evaluation Tool that can compare two videos and evaluate the video stabilization quality between them. Each video’s score is calculated based on the output movement of the video, with each video being evaluated in 3 dimensions: x translation, y translation and z rotation. The acceleration in each dimension is calculated, with higher acceleration causing higher penalty. In short, the more shakiness in the video, the lower score it receives. Using this tool, Vidhance-enabled smartphones have consistently proven to perform better than other solutions, even in challenging environments.
Setting a New Standard for Smartphones
Of course, the more tasks a smartphone handles, the faster its battery drains. It’s a fact of smartphone ownership. Recognizing this, Imint has engineered Vidhance to consume as little power as possible. The company continues to improve upon that with each new generation of the Vidhance software, ensuring the users not only get the results they want from recorded video but also an effortless, enjoyable experience of shooting it.
Imint’s Vidhance Video Stabilization software is addressing all concerns—from the inherent instability of the camera itself, to movement within the environment being recorded, to the removal of distracting video artifacts in the recording. While Vidhance covers all its bases now, it will continue to improve to pace with consumers’ growing expectations from their smartphones.
