Looking back at the first half of this year, it’s clear that CMOS image sensors are dominating both current and future markets. Sony’s decision to discontinue CCD sensor manufacturing to focus on CMOS technology underscores this shift. The latest CMOS sensors outperform their predecessors in nearly every aspect—speed, integration, power efficiency—and now even surpass CCD performance in areas like low-light imaging and noise reduction.

Driven by consumer demand for higher resolutions without increasing camera size or cost, pixel sizes have shrunk dramatically. We’re now approaching the physical limit of 1μm pixels. Industrial applications are following suit: smaller pixels allow more resolution within a given optical format—potentially enabling existing lenses to capture finer details and providing designers with greater flexibility.

While global shutter CMOS sensors still face challenges at smaller pitches, their advantages in speed and integration can’t be ignored. Meanwhile, CCD technology, though maturing, remains relevant for niche applications requiring extreme sensitivity or specific performance characteristics—particularly when paired with advanced signal amplification techniques like electron-multiplying CCDs.

Advances in Image Processing

As sensor quality improves, manufacturers spend less time compensating for inherent defects—a trend that enables smaller camera designs and lower costs. This efficiency extends to specialized cameras used in metrology and medical imaging: while maintaining the same physical dimensions, these devices can now incorporate more complex processing algorithms without compromising performance.

We’re seeing greater integration of features like digital zoom, image stabilization, and color correction—functions previously requiring bulky hardware or external processors. The trajectory points toward even deeper levels of on-sensor computation in coming years.
