Isolating the lens assembly and LCD from a digital camera
I hope you can help. I'm trying to make a functional pair of night vision goggles based on the premise that digital camera photosensors detect IR range light while the human eye cannot. I have an old, functional Sony cybershot that I'm willing to scrap for the job, but the innards are far more complicated than I was expecting. As I am trying for a wearable, head mounted unit, I would like to shave off as much bulk from the camera unit as possible -- I do not, after all, still need picture taking capability anymore, merely a digital display. Any suggestions on where to begin?
EDIT: Correct me if I'm wrong, but the more I think about this the more
it seems like it would be more practical to buy a standalone microcamera and mini LCD. However, what method of output and input would these typically use? Would a simple microcontroller like Arduino suffice to perform all the necessary processing to feed video from the camera to the display? Does any of this even sound reasonable?
Thanks in advance and sorry if photography isn't the right section for this,
