Camera Module Information:
Note that the OV7620 camera module has a specified resolution of 664x492 pixels. This is technically the number of raw sensor locations. As such, the OV7620 is actually limited to 320x240 pixel images in full 24-bit RGB color.
Also note that if an external clock is desired, Y1 and C1 will have to be removed from the C3188A evaluation board, and a jumper will have to be placed at J1.
