Blooming – This is an image artifact that can affect the quality of the image
(Smear is another artifact – see below)). Blooming is an overflow of photodiode
charge into neighboring pixels. It can occur when trying to image a very bright
spot. It results in a distorted image but can be avoided by using correct lighting,
Box Dimension – Dimensions of the packaging carton in which a KAV item is shipped,
expressed in inches and centimeters (international).
Box (Boxed) Weight – Weight of item for shipment, includes both the weight of the
product and the shipping materials.
Bright/Dark Switches – On 7300 and 7600 Video Flex cameras and MVP products, a
button in the base which allows the user to brighten or darken the picture being
displayed by the camera. This adjustment is also possible using the Applied
Vision ™ for Windows software. See also Brightness.
Brightness – The quality or condition of being bright; the luminous quality of a color (as
distinct for hue) by which it is regarded as approaching the maximum luminosity
of pure white or the lack of luminosity of pure black. Brightness control, is more
properly called black level. It adds or subtracts an offset, or bias, into the red,
green, and blue signals. This control should be adjusted so that black picture
content displays as true black on your monitor. Mis-adjustment of this control is
the most common problem of poor quality picture reproduction on computer
monitors, video monitors, and television sets. The setting is somewhat dependent
upon ambient light. Brightness may be adjusted on all Ken-A-Vision products
using Applied Vision ™ for Windows. Some camera units have a button in the
base of the unit for adjustment of brightness.
Auto Brightness - is a feature of some cameras that allows them to obtain the
correct white balance, on a subject, instead of requiring the operator to
adjust white balance manually.
Brightness Compensation – same as Auto Brightness.
Manual Brightness - Ability of the user to change the brightness or darkness of a
displayed image overriding any preset (default settings).
C-Mount lens - a type of lens mount commonly found on movie cameras, television
cameras, and trinocular microscope phototubes. The C-mount lenses typically
provide a male thread which mates with a female thread on the camera. [The
thread is nominally 1 inch in diameter, with 32 threads per inch, designated as "1-
32 UN 2A" in the ANSI B1.1 standard for unified screw threads. The register
(distance from the lens mount flange to the focal plane) is 17.526 mm (0.69
inches) for a C-mount, 12.52 mm for the otherwise identical CS-mount]. The
letter "C" is said to stand for "cine", the original application being movie camera
lenses.
