Sparkfun Camera

MagnaChip HV7131GP CMOS Camera Module

8-Bit Output Format Support:

  • YCbCr 4:2:2
  • Bayer

the libdc1394 howto
provides an excellent introduction to the Bayer format.

the starting row and column determine the Bayer format

  • even BGGR
  • odd GRBG

basically because the camera is slightly larger than 640x480 you can set
the window for usage:

  • Row 2 and Column 2 with Window Heigh 640 and Width 480 produces
    Bayer BGGR
  • Row 1 and Column 1 with Window Heigh 640 and Width 480 produces
    Bayer GRBG

the odd/even are dependent on the orientation of the scan.

Information gathered from the Sparkfun Forums

although the camera does support a 16-bit mode, the ribbon cable only
provides support for the 8-bit mode.

  29. busonerd states - "My guess for the parts values would be a ~600ohm @ 100MHZ ferrite bead (B1 and B2), current capacity ~100-200 ma, and a 0.1uf caps(C1 and C2). You really can't go wrong with the ferrite bead - just get a higher impedance + higher current capacity one if in doubt. For the caps(C1 and C2) - if you really want to be paranoid, use an 0.47uf, an 0.1uf and an 0.01uf - with the smaller values nearer the connector - but that is guaranteed overkill."
