Glossary

Interlaced

A method of image scanning whereby the image data is divided into

scanning

fine horizontal lines which are displayed in sequence starting from left

 

to right and then from the top to the bottom of the screen. The even-

 

numbered lines and odd-numbered lines are displayed alternately.

 

 

Progressive

A method of image scanning whereby the image data from a single

scanning

image is scanned sequentially from top to bottom to create a single

 

image.

 

 

Refresh rate

The light-emitting element of a display maintains the same luminosity

 

and colour for an extremely short time. Because of this, the image must

 

be scanned many times per second in order to refresh the light-emitting

 

element. The number of refresh operations per second is called the

 

"refresh rate", and is expressed in hertz (Hz).

 

 

Resize

This function is use to project computer images that have a resolution

display

or more than or less than the projector's panel resolution to be projected

 

so that they fill the whole of the projection area.

 

 

Security

A device consisting of a projector case with a hole in it that a

lock

commercially-available theft-prevention cable can be passed through in

 

order to secure the device to a table or pillar. This projector is

 

compatible with the Microsaver Security System manufactured by

 

Kensington.

 

 

SDTV

An abbreviation for Standard Definition Television. It refers to standard

 

television systems which do not satisfy the conditions for High-

 

Definition Television.

 

 

sRGB

An international standard for colour intervals that was formulated so

 

that colours which are reproduced by video equipment can be handled

 

easily by computer operating systems (OS) and the Internet.

 

 

SVGA

A type of video signal with a resolution of 800 (horizontal) x 600

 

(vertical) dots which is used by IBM PC/AT-compatible computers.

 

 

S-Video

A video signal which has the luminance component and colour

 

component separated in order to provide better image quality.

 

It refers to images which consist of two independent signals: Y

 

(luminance signal), and C (colour signal).

 

 

Sync.

The signals output from computers have a specific frequency. If the

(Synchroni-

projector frequency does not match this frequency, the resulting images

sation)

will not be of a good quality. The process of matching the phases of

 

these signals (the relative position of the crests and troughs in the

 

signal) is called "synchronisation". If the signals are not synchronized,

 

problems such as flickering, blurriness and horizontal interference can

 

occur.

 

 

Tracking

The signals output from computers have a specific frequency. If the

 

projector frequency does not match this frequency, the resulting images

 

will not be of a good quality. The process of matching the frequency of

 

these signals (the number of crests in the signal) is called "tracking". If

 

tracking is not carried out correctly, wide vertical stripes will appear in

 

the projected images.
