Are there any iphone / ipad camera hardware filters that can be controlled by the application?

I posted the same question on apple.stackexchange ... maybe it works better here.

Does anyone know if there are any hardware camera / CCD filters on the iPhone (any version) (e.g. polarizing filter, IR filter, band-pass filter) that can be controlled using software?

If so, how can I and / or where can I find documents about this? I wrote one app for iPad using Xcode, so I'm not quite a beginner.

Thanks for any help.

Edit

I'm trying to develop an application, so I assume that there are no external devices / filters to the device or camera , only an iPhone / iPad with standard equipment.

Check the CIFilter class links, this can be used to achieve your goal. There are many different filters, and I believe that they can be applied in real time, or at least within milliseconds of real time.

In particular, a list of all available CIFilters can be found here.
