At the ISSCC you see the future of sensor technology: Global shutter and 3 layer sensor tech!
I always thought that the next big leap in image quality would be the move to three-layer sensor technology. Sigma has named the Foveon sensor as such. At Isscc from February 16-20, this will be one of the main points of discussion.
The 3-layer sensor technology (Foveon) is considered a potential future of imaging because it captures all three primary colors (RGB) at every pixel location, unlike traditional Bayer sensors that interpolate colors using a mosaic pattern. Here’s why it’s promising:
- Superior Color Accuracy: Each pixel captures full RGB data, resulting in more accurate and natural colors compared to Bayer sensors.
- Sharper Images: Without a Bayer filter, there’s no need for demosaicing, reducing artifacts like moiré and providing sharper details.
- Better Micro-Contrast: Foveon sensors excel at reproducing fine details and textures, offering superior micro-contrast ideal for high-quality photography.
- Simpler Workflow: Eliminates the need for anti-aliasing filters and complex post-processing for color reconstruction.
- Potential for Innovation: With advancements in material science and processing technology, the challenges of high noise and limited ISO range in Foveon sensors can be addressed, unlocking their full potential.
If these challenges are overcome, Foveon and similar 3-layer sensors could redefine image quality, particularly for fields like fine art, product, and landscape photography.
A whole series of new global shutter sensors will also be presented at the same event. They are particularly interesting when it comes to video use. As a photographer, I’m more interested in seeing 3-layer technology in a future full-frame mirrorless camera. Sigma is working on it, but hasn’t gotten some production issues under control yet. Sony has patented several “ideas” in recent years, but there is still no indication of when their new sensors will be market ready.ensors will be market ready.
