why does nexus one camera pick up ir?

I was playing around with my evo and used my nexus one to film some bootloader stuff and noticed that there was a purple led flashing wildly in the camera shot that I couldn't see with my bare eyes.
As it turns out the nexus one camera picks up on the ir from the proximity sensor, ego does the same. You can point your nexus cam at any ir remote at home to verify, its kinda weird. Any idea why they would do this?
here is some video proof, Video link : http://www.youtube.com/watch?v=nGqVDXAQ87A

Pretty much all digital camera sensors can do that. Try looking at it with your webcam. Digital cameras and SLRs and such may have an IR filter to get rid of that.

True story.

Its pretty much how the Wii works. There is no special camera in there. Those cctv security cameras can use IR for night vision; and I have used a camera and remote as a sort of night vision before.

I've also built a ghetto night-vision set using an an old camcorder viewfinder for the display, a cheap camera phone camera sensor for the camera, and a bunch of IR LEDs to provide "invisible" illumination. Worked pretty well :-D

Almost all camera sensors pick up IR ^^
Try with some phones or webcam, and you'll see =)
Edit : The only way to stop the IR, is to put a filter

Idea to have a rear camera

What about a periscope that you can attach at the top of the screen, making the front camera a "rear camera". I'm thinking in google goggles, AR apps, QR Codes, and maybe a photo .
Even the head of the periscope can rotate to change the orientation withot attach and deattach this accessory, I'm thinking in a hangout that you can show something you are looking at, and after you want to go back to your face.
Crazy idea?

Not crazy at all, someone did something similar to make Nexus One rear facing camera have mirror so it is front facing. Love to see it done. Google it, I don't have any links atm.

they could have installed rear camera.....just 3MP to translate text, recognize sudoku.....for GOGGLES and TRANSLATES!!!
wasn't smart

Anyone with an N7 also has a decent phone in their pocket that can do this do it really isn't necessary. If my N7 did everything my OneX does then why have both?

Yep found a nexus one accessory here.
Picture here
EDIT: removed attached pic(it was huge)
don't know what the dimensions of where the nexus one rear camera is. but this could be made with a tiny amount of tweaking.
Only thing is, the front facing camera isn't exactly good quality.

I had this idea whilst waiting for my nexus to arrive few weeks back, all you need is one mirror to make the camera 'up facing' then You can then hold device flat and lower down like a compass and review / frame stuff up, noting that its flipped so left is right etc.
i Mentioned it here http://forum.xda-developers.com/showthread.php?p=29191027
I just need a non scratched little mirror about an inch square as my test one was mucky and meant picture quality was bit lame.
Tbh i think all we really need is a little view finder to aid lining up from behind and clever apps that use the eg. Vol key as a shutter. That would potentially be more useful to make front facing cam work.

All though I found if you install camera app where volume buttons activate shutter, you can blindly snap while pointing nexus with the back facing you in googles and it seems to work.

[Q] Front Camera Lens Issue??

So when I was taking a picture with my front facing camera on my one it looks to be in some kind of fun house mirror mode... I was looking for a setting with it but I can not seem to find it... Basically when taking a portrait with the front camera if i move my face up or down it has a bug eye/ fun house mirror effect... Am i missing this setting??

Nope mine is also the same, if I'm taking a picture with the front camera it comes out long or strectched out usually at the top. I think it's due to the wide angle lense in the front facing camera.

Thats pretty terrible....

[Q] Front camera laggy on snapchat

Is there a way to make the front camera smoother for snapchat? The back camera works beautifully no lag whatsoever but the front camera is very laggy in certain light conditions hard to take a selfie with the lag.

Works perfectly for me. My kids take selfies daily...no lag.
Do you have a screen protector covering the lens?

nope my screen protector has a cutout for the front camera. It works completely fine in the stock camera app.

Same problem here... only in lower light. Must be an issue with the app.

Front facing camera defective ?

Hello ,
I received my nexus 6 on 2nd Jan directly from motorola.
The front facing camera seems to take very soft (bit pixelated) overexposed images , I also own a moto x 2014 and a nexus 5 the camera on these two is surely better .
Is it possible that i have a defective ff camera ?
I do have a screen protector on but i even tried the camera without a protector on , no luck

Mine too, but only when I use Google Camera.
Using an alternate camera app like OpenCamera produces correctly exposed photos for me. What a shame!
