Where can I find the IR filter in this camera?

Hi, I have a very similar camera it is a dv150f, from samsung as well, and I need to take out the IR FILTER, which comes suppously between the lens and the sensor (ccd or cmos), but it is not there. I have done this with other two different brands, and sensor was there, but with this one I can not find it.

I already broke my camera, I openned the lenses looking for the IR. I found more trouble, and two switches that close and open, one closes the whole lens view, but the other just makes light of a different color, like purple, could this be my IR filter?
