I have good reason to believe that the ov7630, is the same as an ov7620, I 
believe this as the ov6620 and ov 6630 are the same, the only difference is the 
supply voltage, so I guess the same holds true for the ov7630.

In that case, there is a datasheet which documents all the ov7630 registers 
(those you set with the i2c data) here:

Yes, I believe you need to atleast clear bit 5 off register 14, so thats an i2c 
write sequence of:
  {0xa0, 0x21, 0x14, 0x04, 0x00, 0x00, 0x00, 0x10}

But I notice that register 14 currently does not get written at all and its 
rest value is 0x04, hmm.
