BCT Blur Control Technology
Phase One Blur Control Technology (BCT) delivers unmatched image quality in aerial imaging. By combining ultra-high-speed shutters with highly sensitive CMOS sensors, BCT removes the need for mechanical or software-based forward motion compensation (FMC). The result: consistently sharp images, simplified systems, and maximum productivity.
Why motion blur matters in aerial imaging
With modern highly sensitive CMOS sensors it is possible to capture very high-quality images with very fast shutter speeds. At Phase One we call this combination of ultra-high speed shutters and high sensitivity CMOS sensors, Blur Control Technology or BCT.
We control forward motion directly by using very fast shutter speeds that enable the capture of high GSD data from fast-moving aircrafts without the need for complex mechanical or software-based FMC systems. As a result, no compensation is required. Phase One imaging components and solutions are designed to deliver the highest quality data with the highest productivity with the least complexity.
The Challenges and limitations of Forward Motion Compensation (FMC)
Capturing sharp, high-resolution images from a moving aircraft has always been a challenge. When shutter speeds are too long, even the slightest forward motion during exposure creates blur.
Traditional solutions relied on forward motion compensation (FMC) — either mechanical systems that move the camera or sensor during exposure, or software algorithms that try to correct blur in post-processing. Both approaches come with trade-offs: complexity, calibration issues, and reduced accuracy.
- Mechanical FMC adds moving parts that increase maintenance needs and reliability risks.
- Precise calibration is difficult and can easily drift over time.
- Software FMC manipulates pixel data, making it difficult to maintain geometric accuracy.
While these methods can produce acceptable results, they slow workflows, add risks, and increase costs.
Solving motion blur with Blur Control Technology (BCT)
Phase One takes a different approach. Instead of compensating for motion, we control it directly.
Blur Control Technology (BCT) leverages:
- Ultra-high-speed shutters → Freeze motion instantly, even at high ground speeds.
- High-sensitivity CMOS sensors → Deliver crisp, detailed imagery in varying light conditions.
With BCT, aerial imaging professionals can capture high GSD data from fast-moving aircraft — without complex mechanical parts or time-consuming software correction.
