Default Recording Damaging Cameras

Ok, I got a new camera for xmas and over the last week or so a blueish blob has appeared in the center of every picture I take, its only about 3 pixels big but you do notice it sometimes.

So my dad has looked through the pictures I got with it in order and it has appeared to happen after I recorded my red and green lasers together a few weeks back... So obviously my dad has instantly blamed the lasers. Strange thing is the camera never took a direct hit to the lense, it has scanned over it a few times but never directly hit it. Even more strange is that I have recorded with my phone and my old camera hundreds of times and it has never happened.

So could it have been the lasers that caused it? and if it is what can I do to prevent it if I ever record again?

It's blue, that figures. By scanning over the lens, you concentrated all of the powerful laser energy onto the red and green sensors, leaving that section dead to those colours. So blue is all thats left in that area.
Sorry, but likely your camera is cooked and will stay like it.

it might also be possible that they are just hot pixels... google it, if you are lucky, you can still have the pixels remapped.

I'm a bit surprise that taking pictures of the dot would damage a camera that easily. Perhaps you could tell a bit more about how all of this happened:

- how far was the camera from the dot... across the room or close up?
- was the aperture fully open? (should be in the EXIF)
- big scary lasers or low power pointers?

Also, was the dot just 3 pixels or so wide on the photo, or did it just burn out a few pixels at the center of the dot?

I was recording my RGY scanner. Red being 100mw and green being 50mw.

Samsung are rediculous when it comes to registering the camera, it is impossible.

Heres what the problem is anyway, save the attatched picture and zoom in on canary wharf (the building right in the distance). You can see a pink/purple/red blob there.

Picture taken from where I used to live by the way :P.

Use photoshop to get rid of it.

That's pretty lame though. I've directly blasted my camera phone with all kinds of bright lights including my X105 and there is no damage at all...

Same thing happened to my camera but instead of a pink blob I have a yellow/white/black blob that sort of resembles a popcorn. It appeared a few weeks after I started taking videos of my laser um..."experiments". The other thing that I noticed is that when I take pictures of anything black, there's a lot of noise when you zoom in. My guess is the senor's probably shot... :-/

Yep, youve killed some bit of the sensor, not much you can do about that. I accidently killed a few pixels on ym laptop screen with my DIY red.

Just phoned them and got the camera registered... I think. Spoke to someone in india it would seam like... I was told they would phone back to confirm the details but they never phoned back.

I will phone them back after lunch and sort the other half of the problem out. Thinking about it though, if my dad got the camera from say argos for example and he still has the reciept I could simply go back and get it replaced.

Yep. You can probably say it was some sort of manufacturing defect and hope they don't know otherwise. :-X

But in my case, can the camera sensor be replaced? Say, I take it to a service center or something?
