Company Profile:
Tektronix provides test and measurement instruments, solutions and services for the computer, semiconductor, military/aerospace, consumer electronics and education industries worldwide.
Problem-oriented programming language, as distinguished from a machine-oriented programming language. A high-level language is closer to the needs of the problem to be handled than to the language of the machine on which it is to be implemented.

A) The exponent of that power law that is used to approximate the curve of output magnitude versus input magnitude over the region of interest. b) Video - The power function of the electro gun in a CRT. It has become customary in video, as in photography, to extend the meaning and to use gamma as a synonym for the complete transfer function regardless of curve shape. Note: In the electronics system, increasing gamma decreases image contrast. c) Imaging Processing and Display – Nonlinear processing is useful in many television systems as a means of bandwidth limiting, and is normally applied at the camera. Given the predominance of CRT displays, the chosen exponent is related to that of the electron gun (typically 2.2 for systems with 525/59.94 scanning, 2.8 for systems with 625/50 scanning, and 2.22 for SMPTE 240M).

A) In lighting, to add a light which will cause an area to have more light. b) In switchers, to allow one portion of the video to have a greater luminance level. c) In screens, monitors, displays, etc., to cause a word on the display to be brighter, commonly by inverting and surrounding the work with a box of white video.

A) The slope of the transfer function: density (log of reciprocal transmission ) vs. log exposure. It is thus the power function correlating transmission to exposure. b) Gamma in the photographic sense was originally applied specifically to the straight-line portion of the transfer function. Only if all of the photographic densities corresponding to light intensities in the scene lie within that straight-line portion of the transfer function is gamma proportional to contrast. It is sometimes loosely used to indicate either an average or a point slope of the transfer function. Note: In the photographic system, increasing gamma increases image contrast.

In the menu system for DVDs it is necessary to be able to indicate a menu selection since there is no “computer mouse” available. This highlighting is accomplished through a wide variety of graphic arts and post-production techniques coupled with the capabilities provided by the DVD itself.
Industry:Software
The range of voltages allowed for a video signal, or a component of a video signal. Signal voltages outside of the range (that is exceeding the gamut) may lead to clipping, crosstalk, or other distortions.
Industry:Software
A) Shiny areas that suggest intense reflections of light sources. Highlights move when light sources move relative to a surface, but are independent of all other lighting types. b) Highlights may be applied to a smooth surface by both Gouraud and Phong shading, but only the latter computes specular reflections based on the angle between reflected light from a light source and the eye’s line of sight.
Industry:Software
The maximum brightness of the picture, which occurs in regions of highest illumination.
Industry:Software
Most significant bits of a word. Typically, bit 8 through 15 of a 16-bit word.
Industry:Software
The dimension of the gap measured in the direction perpendicular to the surface of a head.
