General Description
The OV6630 (color) and OV6130 (black and white) CMOS Im-
age sensors are single-chip video/imaging camera devices
designed to provide a high level of functionality in a single,
small-footprint package. Both devices incorporate a 352 x 288
image array capable of operating up to 60 frames per second
image capture. Proprietary sensor technology utilizes advanced
algorithms to cancel Fixed Pattern Noise (FPN), eliminate
Note: Outputs UV0-UV7 are not available on the OV6130. The inputs associated
with these respective pins are still functional.

... It should be noted that FREX must remain high long enough to ensure the entire image array has been pre-charged. When data is being output from OV6630/OV6130, care must be taken so as not to expose the image array to light. This may affect the integrity of the image data captured. A mechanical shutter synchro- nized with the frame exposure rate can be used to minimize this situation ...
