IEEE 1394 data transmission mode featuring guaranteed transmission timing and bandwidth. Appropriate for just-in-time transmission of video and audio and computer data.
Industry:Consumer electronics
Special camera mode similar to the ‘B’ setting of a photographic camera shutter. The CCD integrates over a long (userdefined) period, providing very high sensitivity. Object must be stationary, external camera control and a frame memory are needed.
Industry:Consumer electronics
The part of a composite video signal that expresses brightness. Also called Y. Separately transmitted in Y/C (S-video).
Industry:Consumer electronics
The SI measurement of light intensity taken at the surface which the light source is illuminating. The measure of the total lumens falling upon a unit of area. 1 lumen per square meter. One Foot-candle equals 10.76 lux.
Industry:Consumer electronics
Minimum light level needed to achieve a 50% or 100% video output level when the camera is at maximum gain and the lens iris fully open. Can be computed from the nominal sensitivity, lens characteristics and maximum gain.
Industry:Consumer electronics
A lens parameter that defines the minimum distance from a camera lens to the point where an object can still be in focus.
Industry:Consumer electronics
Camera feature where a reference field is compared with current fields. If a difference is detected, the camera outputs a pulse. An ideal feature for security application.
Industry:Consumer electronics
Defines the resolution capability of a lens. Most lenses exhibit their best MTF when operated in the middle of their iris aperture range.
Industry:Consumer electronics
A grey filter added in front of a lens to reduce the amount of incoming light into the camera lens. It has no influence on color.
Industry:Consumer electronics
Type of camera mount in which there is 12 mm clearance between the lens rear mounting surface and the camera’s CCD.
