JPEG and TIFF File Processing
The DCS 620 and 620x cameras support background image processing that produces
JPEG or TIFF RGB files that can be opened directly by any image editing software. This
feature is not available on the DCS 660 or 660M cameras.
The choices for processed files are JPEG Good, Better, Best, and TIFF RGB. JPEG Good
files have the most compression, JPEG Best have the least. The less compression, the
better the quality of the processed file and the larger the file size. The file size varies,
depending on content. TIFF RGB files are not compressed.
When you capture images, they are written to the selected folder using the TIFF Custom
format, regardless of whether processing is turned on. If you turn on processing, JPEG
Best, Better, Good, or TIFF RGB files are created and saved when the camera is not busy
with other tasks such as capturing images.
JPEG files are saved to a JPEG folder and TIFF RGB files are saved to a TIFF folder.
These folders are created on the PC Card when you turn processing on (if they don’t
already exist). If you select the JPEG or TIFF folder to review images, then you capture an
image, a message informs you that images cannot be saved there. The images are saved in
the default folder established in Properties. You can specify whether the original TIFF file
is saved or deleted once the JPEG or TIFF RGB file is saved.
Processing is turned off by default. When you turn on processing, it stays on until you turn
it off, or remove the PC Card.
Processing with Two PC Cards
When you have PC Cards in both slots, images are processed on the card that is active
when you turn on processing. If you make the other card active, processing continues on
the inactive card. For example, if CARD0 is active when you turn on processing, then you
change to CARD1, processing continues on CARD0, but not on CARD1. In this case, if
you want to switch processing to CARD1, you must turn off processing, then turn it back
on. When turned on, processing will automatically be set for the active card (CARD1).
