JPEG
This is a file format for compressing
and saving images. Some of the
information is removed from the
image, thereby compressing and
recording the image data to a
smaller file size. Although the image
quality deteriorates slightly when the
image data is compressed, you are
able to save more images with the
same disk space.
PICT
This is a format for saving image
data. It is a standard graphic format
in Macintosh. It can contain both a
bitmap and draw object. This format
can be used with 24-bit color or 256
shade grayscale. PICT files can be
written and read by most graphic
software and by Simple Text, and
are therefore commonly used when
sending and receiving data across
different software applications.
PNG
Portable Network Graphics. This file
format was developed because of
the image data deterioration of
JPEG and the patent issues
surrounding the GIF format. PNG
offers a very high compression rate.
Profile
This is a color properties file. It
defines the color reproduction area
properties of input and output
devices. The color management
system uses a profile to correct the
color differences between devices
and convert the data when an image
is input or output to or from a device.
RAW Data
When the Record mode on an
Olympus camera is set to [RAW]
Glossary of terms
and an image is shot, the image is
saved as RAW data. RAW data is
the original data from the charged
coupled device (CCD) that has not
been developed inside the camera.
The image processing functions of
OLYMPUS Studio can be used to
develop the image. Changes to the
development process settings are
saved with *.orf as the extension for
the Olympus RAW File format data.
When saved RAW data is opened,
an image is displayed with the
settings in the header applied. To
use this RAW data with a different
application, you must first convert
the data to JPEG or similar file
format.
TIFF
This is a file format for saving
images. When an image is saved
without being compressed, the file
size may be large, but there is little
deterioration of the image quality.
This format is good for saving an
image that will be printed at a larger
size.
USB
Universal Serial Bus. This is a
standard for connecting a computer
with an external device. A USB
cable conforms to this standard and
is used to connect a digital camera
or printer. A USB cable can be
disconnected while the USB device
is still on, and it also enables the
connection of several USB devices
at the same time. USB 1.1 has a
transfer rate of 12 Mbps and USB
2.0 has a transfer rate of 480 Mbps.
