Disk Drive Operations
The ability to save full frame images to disk is a powerful feature. The
YUV and Y10 file types save a frame in the 8150's native format
(luminance and color difference) at either 8-bit (YUV) or 10-bit (Y10)
uncompressed resolution. A YUV or Y10 file takes about three seconds
to save and recall on the hard disk, but takes about six and one half
minutes to save, and about three and one half minutes to recall, on a
floppy disk.
TIFF (Tag Image File Format) was developed by Aldus and Microsoft
for use by PC, Macintosh, and Unix platforms for desktop publishing
and graphic arts. There are several classes of TIF files, including
monochrome, gray scale, palette-based color, and RGB color. The 8150
can read and recall all types of TIF files, including TIFF-B (monochrome),
TIFF-G (gray scale), TIFF-P (palette-based color), and TIFF-R (RGB
color). However, it saves them only as compressed TIFF-R (24-bit RGB,
8 bits per color) files.
When the 8150 saves a TIF image file, it is smaller than a YUV or Y10 file.
However, since the amount of compression varies with image content,
the file size varies also, and it takes significantly longer to save and recall
to the hard disk than the other two image file types. We recommend that
you save an image as a TIF file only if you expect to export it to a
computer for further processing. The save and recall time for a TIF file
varies due to image content, but typically takes the same amount of time
as a YUV or Y10 file, due to the floppy disk transfer speed.
