ANSI LumensA unit of measure used to measure the brightness of a projector. Specifically, measured by projecting a 40-inch diagonal screen into a plain matte white surface, and dividing the screen into 9 parts equal parts of 3 across and 3 down, while measuring the brightness level of each of the 9 parts, and obtaining the average brightness of these 9 parts.
  
Aspect RatioAspect Ratio refers to the proportion of the height and width of a projected screen. Standard projector displays are 4-by-3 (4:3), while HDTV is widescreen, 16-by-9.
  
BrilliantColor(TM)BrilliantColor(TM) technology utilizes a new color-processing algorithm and system level enhancements to enable higher brightness for both business and home projectors while providing truer, more vibrant colors. Through greater flexibility in color processing, BrilliantColor can produce more realistic and lifelike color reproduction.
  
CineViewProprietary line-doubling technology of Mitsubishi Electric that delivers smoother images and clearer pictures in video, especially in movie scenes with fast moving action sequences.
  
Color Enhancer™Color Enhancer™ is exlusive Mitsubishi technology that is designed to enhance the overall projected picture quality. It is designed to deliver vibrant, truer colors, boost brightness and produce smoother images for a stunning viewing experience.
  
Contrast RatioContrast Ratio is the difference in luminance level between the brightest white and the darkest black. The higher the contrast ratio, the deeper and richer the colors are.
  
Digital Keystone CorrectionAn adjustment mechanism that re-scales the projector image when the projector is not set at a 90 degree angle, in order for the image to not be distorted.
  
DLP® TechnologyAt the heart of Texas Instruments Digital Light Processing® technology is the Digital Micromirror Device. The DMD switch has an array of up to 1,310,000 hinged, microscopic mirrors, which operate as optical switches to create a high resolution, full color image. Click here to learn more.
  
DMDDigital Micromirror Device. A chip developed by Texas Instruments that consists of thousands of tiny, moveable mirrors that reflect light to create clear, precise images that can be displayed.
  
Hertz (Hz)Hertz (Hz) is a unit of measure for the frequency equal to one cycle per second, used in measuring vertical scan rates of display signals. Used to be known as CPS, was changed in 1965 to hertz, in honor of Heinrich Hertz, a German physicist. Can also be expressed in multiple units such as 1 Kilohertz (KHz) is 1,000 hertz or cycles, and 1 Megahertz (MHz) is 1 million hertz or cycles.
  
Horizontal Scan RateHorizontal Scan Rate measures the speed it takes for a projected screen to fill its image, drawing a line from one side of the screen to the other. Measured in Kilohertz.
  
IRIS®IRIS® stands for Intelligent Room Illumination Sensor, IRIS gives you the confidence that presentations will be seen clearly by your audience in a variety of room lighting conditions. The sensor automatically detects the level of ambient lighting present in the room, and adjust the contrast and brightness of the projector to give its optimal display.
  
LCDLiquid Crystal Display.
  
LumensLumens is the unit of measure for projector brightness. It is the unit of luminous flux representing a definite rate of light emission. Luminous flux denotes the time-rate flow of light energy, that characteristic of radiant energy which produces visual sensation.
  
Natural Color MatrixA Mitsubishi exclusive award-winning technology. Enables our LCD projectors to produce the most vibrant and realistic colors no other projectors can match by expanding the control of the color spectrum of the projector from RGB (Red, Green, and Blue) to include YMC (Yellow, Magenta and Cyan) - similar to the color range of CRT displays. Each of the six colors can be individually adjusted without affecting the hues of the other spectrum colors. Click here to learn more.
  
NTSCNTSC stands for National Television Standards Committee, is a color TV system represented by a display of 525 horizontal lines per picture frame, and 59.94 field per second. NTSC is also displayed in 4:3 aspect ratio.
  
PALPAL stands for Phase Alternate Line, is a color TV system represented by a display of 625 lines per picture frame, and refreshes at 50 frames per second. PAL is also displayed in 4:3 aspect ratio.
  
Picture in Pictue (P-I-P)Picture in Picture displays dual moving images from two separate sources (e.g., PC and video) at the same time, thus doubling visual information and impact simultaneously.
  
Projection DistanceThe distance between the projector lens and screen.
  
ResolutionThe number of pixels that makes up screen area.  VGA: 640 pixels x 480  pixels SVGA: 800 pixels x 600 pixels XGA: 1024 pixels x 768 pixels SXGA: 1280 pixels x 1024 pixels
  
RGBRed, Green, and Blue. These three colors make up the color spectrum.
  
RS-232CRS-232C better known as serial communication standard, is the protocol of communication used by most, if not all, projectors, to communicate with popular control systems. With Mitsubishi’s ProjectorView device, the RS232c or serial port can readily be assigned and IP address, enabling the connected Mitsubishi projector to be controllable and monitored through a web-based browser.
  
S-VideoA Video signal formats. A VCR with higher resolution than normal composite video. (S-VHS)
  
SECAMIn French, stands for sequential couleur avec memoire, (sequential color with memory in English) is a color TV system very close to PAL, its display represented by 625 lines with 50 fields per second.
  
sRGBA color space that was developed in October 1999 and defined with specifications compliant to the international color standard IEC 61966-2-1. It is a system of color spaces that determines tone, saturation, and brightness. This enables computer operating systems to easily decode and translate color expression into actual color displays.
