TM-6760 Series Progressive Scan Shutter Cameras
Operation
3.11.3 Starting Pixel Configuration
All manufacturers produce identical Bayer CFAs, but there are slight differences between the CCDs
produced by different manufacturers. The first line is generally R and G, except for the Kodak CCD,
which starts with G. The Sony CCD starts with R. The camera timing can be adjusted to start with either
G or R by skipping the very first pixels at each line. Most color interpolation software can select
between a variety of pixel relations, such as R/G start or G/R start, as well as G/B start and B/G start.
Once the correct scanning is configured, the rest of the interpolation will be exactly the same. Please
contact JAI, Inc. for further information regarding CCD manufacturers.

3.11.4 Sync and Data
The individual color data is exactly the same as the pixel data. This means that the timing relationships
of the color cameras are also the same as those of the B/W cameras. For a detailed timing chart, please
refer to each B/W camera’s data sheet and manual. If the framegrabber has a standard B/W
configuration file, then AccuPiXEL color cameras can use that configuration file to operate. The
configuration file may vary, depending on whether the output is standard (RS-644) or Camera Link.
Please consult JAI, Inc., or your framegrabber supplier for compatibility information.
The following diagram is an example of the TMC-6760 (same as TM-6760).
