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 color. RLE can be
used with monochrome, 16-color and 256-color BMP image files. (Image Creator 1.0
does not support files compressed using RLE.)
TIFF
Abbreviation for Tagged-Image File Format. This type of file is used to exchange
documents between computers. Color levels of monochrome, 256 colors and 16.7
million colors are supported. TIFF files in 16.7 million color format can include
transparent color.
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. (Image Creator 1.0 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 information 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.
PowerPoint
Application software for creating presentations which is included as part of Microsoft
Office. 95, 97, 2000 and 2002 versions are available, but the Image Creator 1.0
software which is bundled with the projector is only compatible with the 97, 2000 and
2002 versions.
