Abstract :
We have developed an imaging system comprised of a sensor having White-RGB color filter array and back end image processing chain (IPC) that enables seamless integration with existing imaging solutions. The key components of our imaging system are 5 megapixel, 1.4um pixel CMOS image sensor covered by White-RGB color filter array and hardware-friendly algorithm which is responsible for conversion of native White-RGB data stream into Bayer RGB and capable to do sharpening and noise suppression simultaneously. We show that our solution provides artifact free images and outperforms alternative solutions both in terms of visual assessment and SNR improvement.
