9 Glossary
The following terms might have additional meanings. The definitions that follow are in the context of the HDV500 horizontal digital video system.
A
accuracy
The maximum error that the system will produce when measuring a true standard.
ampere (amp)
The base unit of electric current in the International System of Units (SI).
aperture
An optical element which limits the diameter of the optical bundle that can pass through a specific plane.
arc second
A unit of measurement that describes the magnitude of an angle. It is typically used for small angles that cannot be practically described using degrees as a unit of measurement and is 1/60th of an arc minute.
axis
A direction which allows movement and along which dimensions can be measured. In the HDV500, the X-axis is horizontal from left to right, and the Y axis is vertical from bottom to top.
axial runout
The error between an item and the central axis caused as a result of the rotating component not being parallel. In other words, an angular error in the component will contribute to greater axial runout.
B
blooming
A condition where the parts of the video image are distorted by oversaturated bright regions, making objects appear larger than they really are.
C
CAD file
See Computer-Aided Design.
CCD
See charge coupled device.
