UL, CSA, FCCB, TUV and VDE).
E. Image Recording Features
Here are some special features of the Digital Palette Film Recording system:
o It is a variable and high addressability system ranging from 256 to 4096 pixels. It
will respond to the resolution requirements of the software file that is being imaged.
o There is progressive line scan — one line at a time which enhances image resolution.
o The system is capable of imaging up to 16 millions colors; 8 bit per primary color,
or 24 bits total.
o Exposure time is faster since scanning starts with the brightest level of each line,
rather than beginning at full white.
o In the Model CI-5000, a Buffer Queue Mode provides an additional 512Kb of
buffer memory. This frees up the host computer while imaging is taking place.
There is 128K of buffer memory in the Model CI-3000.
o A background Mode allows the system to vary the color intensity in the background.
With this feature, it’s possible to lighten or darken areas of the background in order
to highlight the graphic image. Also, this mode makes it possible to select color for a
previously black background.
o A COS
4
correction increases the radial luminance of the CRT to prevent light fall-off
in the corners. This provides a more even exposure in the finished print/slide — no
dark corners.
o A resident test image allows the customer to set up and check the system before
connecting it to the host computer.
o Image Sizing/Configuration - Utility software makes it possible to “Zoom” an image
by +5%. This enables the customer to enlarge or shrink the image to suit individual
needs.
