Explanation of terms

Following are definitions for some of the terms used throughout these Operating Instructions.

PowerPoint

Application software for creating presen-

tations which is included as part of

Microsoft Office. 95, 97 and 2000 ver-

sions are available, but the JPEG

Convertor software which is bundled with

the projector is only compatible with the

97 and 2000 versions.

JPEG

Abbreviation for Joint Photographic

Experts Group. JPEG is the name of an

international organisation which was

jointly established by the ISO and the

ITU-TS (formerly the CCIT), but the term

is normally used to refer to the specifica-

tions for the still picture compression

algorithm which was formulated by the

JPEG. This algorithm allows still images

such as photographs, single frames of

moving images and scanned images to

be compressed to up to 1/100th of their

original sizes. However, images which are

compressed in this way cannot be fully

restored to their original quality (some

deterioration in quality occurs), so that

compression rates of 1/5 to 1/30 are

normally used. Because of differences in

colour separation, two format sub-types

are used: RGB (red, green and blue) and

CMYK (cyan, magenta, yellow, black).

The projector and the JPEG Convertor

software do not support the CMYK sub-

type of JPEG file.

BMP

Abbreviation for BitMaP . This is the

standard image format for the bitmapped

files (image files consisting of a collection

of dots) which are handled by Windows.

Colour levels of monochrome, 16 colours,

256 colours and 16.7 million colours are

supported.

RLE

Abbreviation for Run Length Encoding. It

can be used to achieve high rates of

compression for image files which contain

large areas of a single colour. RLE can be

used with monochrome, 16-colour and

256-colour BMP image files. (JPEG

Convertor does not support files com-

pressed using RLE.)

TIFF

Abbreviation for Tagged-Image File

Format. This type of file is used to

exchange documents between comput-

ers. Colour levels of monochrome, 256

colours and 16.7 million colours are

supported. TIFF files in 16.7 million colour

format can include transparent colour.

LZW

Abbreviation for Lempel-Ziv-Welch. LZW

is a compression method used for TIFF

files, and is named thus because it was

developed by three people named

Lempel, Ziv and Welch. It compresses the

files by converting patterns within the

images into short codes. There is no

deterioration in image quality resulting

from compression, but high rates of

compression which are comparable to

JPEG files cannot be expected to be

obtained. (JPEG Convertor does not

support files compressed using LZW.)

DCF

Abbreviation for Design rule for Camera

File system. DCF is a standard which was

established by the Japan Electronic

Industry Development Association

(JEIDA) with the aim of realising a

common image file format, directory

name format and file name format for the

images used with digital still cameras. It is

based on recommendations such as Exif

Version 2.1.

Exif 2.1

Abbreviation for Exchangeable Image File

Format. This is an image file format which

was established by the Japan Electronic

Industry Development Association

(JEIDA). It defines the common informa-

tion format and range of application for

images used with digital still cameras,

centring around TIFF and JPEG-format

images. Version 2.1 is the latest version of

the Exif standard.
