Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
a) Color images are metameric matches when their spectrally different color stimuli have identical tristimulus values.
The requirements for such a metameric match can be calculated for a specified viewing condition (and for viewing conditions other than those specified, the chromaticity will not be judged to correspond). b) The corresponding color chosen for the metameric match will not provide a spectrophotometric match. In practical applications, spectrophotometric matches are of only academic interest, and metameric matches are sought.
c) Color match, metameric, resulting from calculations based upon colorimetry, produces a visual match as evaluated by the CIE description of human observers.
Industry:Entertainment
A technique proposed in some ATV schemes to increase the VBI (and, sometimes, decrease the HBI) to deal with wide aspect ratios. See also Burn.
Industry:Entertainment
Any of several means of specifying colors according to their individual components. See RGB, YUV.
Industry:Entertainment
A component of a digital video system that provides a means of establishing colors (foreground and background) using a color lookup table to translate a limited set of pixel values into a range of displayable colors by converting the colors to RGB format.
Industry:Entertainment
A piece of black plastic attached to the front plastic panel of the Indigo chassis that covers either the top or middle drive slot.
The blanking panel is removed after installing a drive in the slot that it was covering.
Industry:Entertainment
The phase of the chroma signal as compared to the color burst, is one of the factors that determines a video signal’s color balance.
Industry:Entertainment
A circuit on the video module which strips blanking sync and burst from the program output of the switcher and replaces it with blanking and sync from a reference source. This process ensures that sync and blanking do not contain any unwanted timing shifts, and the record VPR is always receiving constant relationships of sync, blanking, and burst.
Industry:Entertainment
In planar modes, the display memory is separated into four independent planes of memory, with each plane dedicated to controlling one color component (red, green, blue, and intensify). Each pixel of the display occupies one bit position in each plane. In character modes and packed-pixel modes, the data is organized differently.
Industry:Entertainment
An ATV technique that adds information to blanking areas that is supposed to be invisible to ordinary sets but can be used by an ATV set for increased resolution and/or widescreen panels.
