CMOS The Future of Image Sensor Technology

CMOS imaging is trending to become the dominant imaging technology. Initially, CMOS was limited by its inherent noise. Architectures were then essentially analog and the idea of integrating the image processing features with System On Chip (SoC) technology was yet to be considered. However, it is...
