Image stabilization for camera modules has become one of the key technologies for improving capture quality.

The stabilization technologies used in camera block modules are mainly divided into two types:

optical image stabilization and electronic image stabilization. But why do SONY FCB full-HD and 4K

auto-focus camera block modules all adopt electronic image stabilization instead of optical image stabilization? 01 Optical Image Stabilization

02 Electronic Image Stabilization (EIS)

02 Electronic Image Stabilization (EIS) Principle: Unlike optical image stabilization, electronic image stabilization uses software algorithms to crop a partial area from the frame and applies the remaining area for shake compensation to counteract vibration. Advantages: This approach eliminates the need for high-cost vibration components and complex mechanical structures, significantly reducing component and production costs. Disadvantages: Electronic image stabilization requires cropping part of the frame, which may reduce image resolution. Given the significant cost-saving advantage of electronic image stabilization, which effectively lowers the overall cost of camera block modules, SONY has adopted a series of methods to address the potential resolution loss caused by frame cropping: 01 Advanced Software Algorithms The electronic image stabilization technology in SONY auto-focus camera block modules is implemented through built-in gyro sensors and high-performance image processing chips, enabling real-time detection and compensation of image shake. For instance, modules such as the SONY FCB-EV9520L and FCB-9500 series (including FCB-EW9500H, FCB-EV9500M, and FCB-EV9500L) offer two stabilization modes: "Super" and "Super+", designed for different vibration intensity environments. This flexible mode switching ensures clear and stable images in various complex scenarios. 02 Wide Correction Area SONY’s electronic image stabilization technology utilizes the wide correction area of high-pixel sensors to reduce image shake more effectively. For example, the FCB-EW9500H and FCB-ER9500 employ 4-megapixel and 8-megapixel image sensors respectively, providing ample room for shake compensation. This allows the image to remain sharp even under severe vibration conditions. 03 Multi-Dimensional Stabilization Capability Compared with optical image stabilization, electronic image stabilization can handle not only horizontal and vertical vibration but also effectively compensate for rotational shake. This multi-dimensional stabilization capability makes SONY auto-focus camera block modules perform exceptionally well in complex environments, such as drones, vessels, bridges,

and vehicle-mounted surveillance, where electronic image stabilization significantly reduces image blur caused by mechanical vibration or environmental factors. 04 High-Resolution Imaging Quality Thanks to their superior high-resolution imaging quality, SONY Full HD and 4K auto-focus camera block modules only crop

an extremely small portion of the frame during shake compensation, which barely affects the integrity and clarity of the overall image. Combined with large photosensitive areas and high-pixel sensors, this efficient shake compensation technology ensures stable, high-quality image output even in challenging environments. 03 Conclusion

The electronic image stabilization technology employed in SONY auto-focus camera modules not only avoids resolution degradation

caused by image cropping, but also more effectively reduces motion blur and maintains stable, sharp imagery in environments with severe vibration and rotation through advanced software algorithms, a wide correction area, and multi-dimensional stabilization capabilities.
