IR/non-IR mode software-switch for camera?

Hello,

I'm about to buy a RaspberryPi with a camera module. My main immediate goal is experimenting with video (in both IR and non-IR modes).
However, I don't see the point in buying two cameras when I will only be able to use one at any given moment...

As the IR module is a stripped-down version of the non-IR one, I assume the non-IR module should have (potential) IR capabilities. Am I right?

If so, is there a way to switch IR/non-IR video modes (by software!) within a single (in principle, non-IR) camera module?
It would be great if I could simply buy one camera to record in both IR and non-IR modes...

Cheers,
Leandro

The only difference is that the IR camera lacks a physical IR filter and thus also records (in normal photography unwanted) IR light. You can buy an IR block filter and have that move in front of the lens by a servo.

Just be aware that IR block filters don't come cheap so it would probably make more sense to buy both types of cameras instead of one + external filter.

Just FYI, you can buy 2 pieces of 9.5 mm diameter IR filter (1% cutoff at 700 nm) for $6.50 with shipping included. The servo to move it in front the camera probably costs more. http://www.ebay.com/itm/9-5mm-Optical-U ... 0529710153
