Aperture

See: F-number (F-stop)

The F-number, also known as F-stop or numerical aperture, defines the amount of light that can pass through any lens setup.

Lens Types

Virtually all cameras need a lens of some kind to collect the light that is scattered from the surface of an object.

Vision Software

The basis of all imaging software is the ability to acquire, transfer, manipulate and interpret the pixel data output by a camera.

Glossary (Acquisition)

Acquisition

All acquisition signal types transmit image data from the camera to the host system. Each technology has its own strengths and weaknesses and not all mechanisms are suitable for every application.

PC Bus Architectures

There have been three major bus interface standards found on PCs since the original PC/AT: the ISA bus, the PCI bus and more recently the new PCI Express bus standard.

Pre-processing

Including pre-processing in the acquisition path can reduce demand on the host PC and can sometimes pre-select data for transfer.

Processors

A processor is the central processing unit (CPU) of a computer system.
