Comparison of Smartphone Camera Anti-Shake Technology: OIS, EIS, and the Battle of the Six-Axis Hybrid Stabilization System

As the photography functions of smartphones continue to iterate and upgrade, anti-shake technology has become one of the core factors determining the quality of the final product. From snapshots, sports scenes to night scene creation, users' demand for the stability of the picture is increasing day by day. This article will deeply analyze the technical principles and performance of the current mainstream OIS (Optical Image Stabilization), EIS (Electronic Image Stabilization) and six-axis hybrid stabilization systems to help you make a more informed choice when purchasing.

OIS the earliest popular anti-shake solution, which compensates for the effects of hand tremor through the physical displacement of the lens group or sensor. Its principle is to a gyroscope to detect the direction and amplitude of the mobile phone shake, and to drive a miniature motor to adjust the position of the lens to keep the light stable. The traditional OIS has a shake angle of usually ±1°, and has obvious advantages in low light environment, by extending the exposure time to improve the of light, while reducing blurring.

Advantages: Low impact on image quality, no need to sacrifice pixels or picture cropping; Outstanding in low light, suitable for night scene, low light portrait and other scenarios.

Limitations: High hardware cost, large space occupation; Lim anti-shake range, it is difficult to cope with violent movements or high frequency vibration.

EIS relies on algorithms to achieve anti-shake, by analyzing the difference between video frames, dynamically adjusting the picture cropping area to compensate for shake Its principle is similar to "dynamic cropping", using redundant edge pixels of the sensor to offset shaking, but it will sacrifice some field of view and resolution.

Advantages: No additional hardware is required, low cost and easy to integrate; Support ultra-wide-angle lenses, suitable for sports video shooting

Limitations: Significant image quality loss, especially in low light environments where noise increases; The effect of anti-shake is limited by the of the sensor, and high-end models perform better.

Six-axis hybrid anti-shake technology (such as Vivo's micro gimbal, Huawei's Sensor Shift) is an innovative solution that has emerged in recent years, combining the physical stability of OIS with the algorithm optimization of EIS. Taking Vivo's micro gimbal as an example, adopts a "dual ball suspension" structure, and through the irregular magnetic movement frame, it achieves a shake angle of ±3°, covering an area 3. times that of the traditional OIS. Combined with the AI motion detection algorithm, it can track and compensate complex shakes in real time.

Technical Breaks:

1.Multi-dimensional anti-shake: It supports X/Y axis translation and R-axis rotation compensation, covering more motion directions.

2.Dynamic compensation: By shortening the exposure time and optimizing the focusing algorithm, the success rate of sports snapshots is improved.

3. Low light enhancement: Combined large aperture sensors (such as f/1.6) and RAW domain noise reduction, night photography is cleaner.

Typical Application Scenarios:

1.reme sport shooting (skateboarding, cycling).

2. Handheld night scene long exposure.

3. Video focusing and cinematic movement.

Pue image quality: Choose OIS or a six-axis hybrid system first, with a large sensor;

Focus on video: A six-axis hybrid systemsuch as a micro gimbal) EIS combination is more stable;

Budget limited: EIS scheme has high cost performance, but need to image quality loss.

As AI technology advances, anti-shake solutions are transitioning from mere physical to intelligent optimization. For example, vivo's "Object Tracking" technology can lock onto moving subjects and maintain focus, while Huawei's AIS (AI-Shake) predicts jitter trajectories through machine learning. In the future, the synergistic optimization of sensors and chips will further enhance anti-shake precision while also reducing power consumption, propelling mobile photography towards professional levels.

The evolution of mobile phone anti-shake technology is essentially driven by users' demand forcapturing cinematic moments on the go." Whether it's the classic reliability of OIS, the flexibility and lightness of EIS, or the breakthrough performance the six-axis hybrid system, they all enhance the mobile photography experience in different dimensions. When choosing, it's important to consider your own shooting scenarios and budget so that anti-shake technology can truly become an aid to creativity rather than a limitation.
