[http://www.magnachip.com MagnaChip] HV7131GP CMOS Camera Module

* 640x480 (actual 652 x 488 )
* [[[Media:HV171GP.pdf]] datasheet]
* on sale at [http://www.sparkfun.com/commerce/product_info.php?products_id=637 Sparkfun] for $19.95
* SMD Connector is a [[[Media:df18.pdf]] DF18 Hirose Connector]
* SMD Connect available from [http://www.sparkfun.com/commerce/product_info.php?products_id=638 Sparkfun] for $0.95
* [http://www.sparkfun.com/commerce/product_info.php?products_id=7904 Break out Board]
* [[SparkfunCameraFPGA]]
* AVR project based on a similiar cameras - http://www.jrobot.net/Projects/AVRcam.html

8-Bit Output Format Support:
* <code>YCbCr 4:2:2</code>
* <code>Bayer</code>

the [[[Media:libdc1394.pdf]] libdc1394 howto] provides an excellent introduction to the Bayer format.

the starting row and column determine the Bayer format
* even <code>BGGR</code>
* odd <code>GRBG</code>

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 <code>Bayer BGGR</code>
* Row 1 and Column 1 with Window Heigh 640 and Width 480 produces <code>Bayer GRBG</code>

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.

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."
