GLOSSARY
  | 
  | attenuate incident light; screens with gain more than 1 direct more incident  | 
  | 
  | light to the audience but have a narrow viewing angle. For example: An  | 
  | 
  | image reflecting off a 10 gain screen appears 10 times brighter than it would  | 
  | 
  | if reflected off a matte white wall. Curved screens usually have larger gain  | 
  | 
  | than flat screens.  | 
Gamma ➤ | A feature provided on Madrigal Imaging   | |
Correction | 
  | boosts the blue color output when required to provide improved picture  | 
  | 
  | intensity and color uniformity.  | 
Geometry ➤ | The reproduction of a straight and rectangular image.  | |
Help Page ➤ | A display of help information on the projection screen.  | |
Horizontal | ➤  | Also called horizontal scan rate or line rate, this is the frequency at which  | 
Frequency  | 
  | scan lines are generated. Horizontal frequencies vary amongst sources.  | 
Hot Spot ➤ | A circular area of a screen where the image appears brighter than elsewhere  | |
  | 
  | on the screen. The hot spot always appears located along the line of sight  | 
  | 
  | and "moves" with the line of sight. High gain screens and rear screens  | 
  | 
  | designed for slide or movie projection usually have a hot spot.  | 
Input | ➤  | A physical connection route for a source signal defined by two numbers;  | 
  | 
  | a switcher number and a slot number. If the switcher number is 0, the input  | 
  | 
  | is a projector input.  | 
Input Memory ➤ | A setup memory which is associated with a particular projector or  | |
  | 
  | switcher input.  | 
Interface | ➤  | A device that accepts an input signal for display by the projector.  | 
Interlace | ➤  | A method used by video tape players and some computers to double the  | 
  | 
  | vertical resolution without increasing the horizontal line rate. If the resulting  | 
  | 
  | frame rate is too low, the image may flicker depending on the image content.  | 
Keypad ➤ | A device which allows the user to control projector settings and operation.  | |
  | 
  | There are four different keypad types which may be used with the projector:  | 
  |
