Hi Michael!

Sorry! I don't have realized, that this camera is a dual tapped one! This
is NOT supported yet by the driver. To get a frame is possible, but the
following steps are theoretically, because I don't have tested it:

1. The config file is p2b2tn00.exo, because the data input is 16bit.

2. You have to divide the vertical size (config file) by two (484 / 2 =
   242), because two lines are read in parallel. (This is also the reason,
   why you only get a half image).

3. Due to point 2 the value read with CR_GET_HEIGHT (test_itifg.c) is now
   not valid. Please multiply it by two.

4. LUT 0 have to be set correctly. Copy the PCD_LIN_LUT call
   (test_itifg.c) also into the 8bit case branch and set PIXEL_SIZE entry
   (config file) to 16. (The pixel size is only important for the LUT's -
   not for the depth of your image)

5. With a little luck now you get an UNSORTED image. This means you get
   alternate pixels from odd and even lines and have to resort it by hand.
   Later (to get the image is for the first step difficult enough) you can
   modify iti_src_init (itifgBuf.c) in a manner, that the board resorts
   the image while transfering it.

Please mail me about any success or problems, because in the next weeks I
have to connect a Kodak ES4.0 (4 channel tapped) and have to solve the
same problem.
