Hi George,

I highly doubt that is due to interpolation.

You can certainly test this by simply creating a raw image file...  I can
see if you are doing compression, that might slow things up...but
interpolation should be being done in hardware, and therefore take up
literally no additional time.  But again, I don't know what different
manufacturers do, so I really can't say.
