What determines the connectivity bandwidth needed in a machine vision system?
This article reviews resolution, definition, frame rate, and bit depth and how they impact connectivity bandwidth requirements. It then looks at a practical example of the requirements for an effective automotive pedestrian imaging system, including the importance of the Johnson criteria for night vision. Pixels, their sizes, numbers, and composition are the bedrock upon which […]
What are the key specifications of machine vision sensors?
Charged-coupled devices (CCDs) and CMOS active pixel sensors (CMOS sensors) are the primary image sensor technologies. They rely on lenses and other optical components to deliver the image to be captured. This FAQ reviews the differences between CCDs and CMOS sensors, some key specifications of image sensors, the concept of quantum efficiency, and some related […]
