Understanding Camera Module Actuators and Their Role in Imaging

A camera module actuator is a critical component in modern imaging systems. It controls the precise movement of lens elements to achieve various functions:

• Autofocus (AF) – Adjusts lens position to focus accurately on subjects at different distances.
• Optical Image Stabilization (OIS) – Counteracts hand shake and vibrations for sharper photos and smoother videos.
• Zoom Functions – Moves lens groups to enable optical zoom, maintaining image quality at different focal lengths.
• Advanced Features – Such as ultra-close-up macro photography and 3D sensing in AR/VR.

These actuators must operate with micron-level precision, extreme reliability, and at high speeds, all while fitting into the compact form factor of modern smartphones. As smartphone manufacturers push for innovations like continuous optical zoom and ultra-high-resolution sensors, the demands on actuator performance are increasing dramatically.

Market Overview: Growth and Key Drivers

The camera module actuator market is expanding steadily, supported by the proliferation of multi-camera smartphones and demand for advanced features. Here are the main drivers:

1. Rising Demand for High-Resolution Smartphone Cameras

Smartphones with 50MP, 100MP, and even 200MP sensors are now common. These high-resolution sensors require highly precise actuators for autofocus and OIS to prevent image blur and maximize detail. The need for precision is fueling innovation in actuator design and materials.

2. Emergence of Continuous Optical Zoom

Unlike conventional cameras that offer fixed zoom steps (e.g., 3x, 5x), continuous optical zoom enables smooth focal length transitions without loss of quality. This feature demands multi-group lens movements, requiring more sophisticated actuator systems.

3. AR/VR and Automotive Applications

Beyond smartphones, camera actuators are finding use in augmented reality (AR), virtual reality (VR), and automotive advanced driver assistance systems (ADAS). These applications require ultra-fast, reliable actuators for functions like depth sensing, driver monitoring, and gesture recognition.

4. Miniaturization and Cost Efficiency

As smartphone designs get slimmer, actuator suppliers are challenged to reduce size while maintaining performance. Cost optimization is also crucial, especially for mid-range and entry-level devices, driving innovation in MEMS (microelectromechanical systems)-based actuators.

Recent Industry Developments: Shaping the Future of Actuators

1. Samsung Electro-Mechanics Leading the Charge with Continuous Zoom Modules

Samsung Electro-Mechanics (SEM), a global leader in camera module components, is pioneering continuous optical zoom technology.
According to The Elec and Android Authority, Samsung is developing advanced telephoto modules where multiple lens groups move independently to create a seamless zoom range, much like professional DSLR lenses.

Key highlights:

• Targeted at Chinese smartphone manufacturers, not Samsung’s own Galaxy devices initially.
• Lens design divided into more than two moving groups for smoother zoom transitions.
• Expected to deliver superior image quality across all focal lengths compared to digital or stepped optical zoom.

This development signals a major leap forward for smartphone photography. Continuous zoom requires extremely precise and durable actuators, representing a significant revenue opportunity for actuator suppliers.

2. Ultra-Close-Up Camera Module with Advanced Ball-Guide Actuator

Samsung Electro-Mechanics has also introduced a groundbreaking ultra-close-up camera module for flagship smartphones.

Features include:

• 200MP resolution with superior image clarity.
• 14.8× optical zoom, enabling sharp ultra-close-up images at distances as low as 12 cm.
• A ball-guide type actuator for precise movement of large-diameter lenses.

This innovation demonstrates how actuator technology is evolving to meet the demands of high-megapixel sensors and macro photography, where even slight inaccuracies can ruin image quality.

3. TDK’s Strategic Transfer of Its Micro Actuator Business

In a strategic move, TDK Corporation announced on April 28, 2025, that it will transfer its Micro Actuator Solution business which includes design, development, and production of camera actuators to QT Investment Inc.

• The transfer is part of TDK’s medium-term plan to optimize its business portfolio and focus on core growth areas.
• The transition is expected to be completed by March 2026.
• This move reshapes the competitive landscape, potentially leading to new entrants or restructured alliances in the actuator market.

This decision reflects the intense competition and capital requirements of actuator manufacturing, as companies reassess their positions in the rapidly evolving mobile imaging industry.

4. Mass Production of Continuous Zoom Modules for Chinese OEMs

Recent reports indicate that continuous zoom camera modules are already entering mass production, but are initially exclusive to Chinese smartphone brands.
Samsung’s strategy to supply these components to external clients before using them in its own Galaxy lineup suggests a dual-track business model:

• Revenue generation through B2B sales to other manufacturers.
• Delayed internal adoption to refine technology and manage risk.

Chinese brands are often early adopters of cutting-edge features, making them ideal partners for initial rollouts.

Technical Innovations in Actuator Design

The evolution of actuators involves advances in both mechanical design and control systems. Some notable trends include:

2. Voice Coil Motors (VCM)

Traditional VCM actuators remain dominant in premium smartphones, offering the precision needed for OIS and high-speed autofocus.
Recent innovations focus on improving:

• Magnetic circuit efficiency.
• Durability under frequent use.
• Power efficiency to extend battery life.

3. Multi-Dimensional Actuation

Modern camera modules often combine multiple actuators:

• One for autofocus.
• Another for OIS.
• Additional actuators for zoom control.

This layered approach allows for advanced functions like simultaneous stabilization and zooming, but increases complexity and manufacturing challenges.
