Recently I took some pics at night and I realised they all have the same dot (2x2 pixels) that shows up 1009 pixels East and 1485 pixels South of the upper left corner of the pic (when in landscape), or at the bottom of the pic slightly left of the middle. I use an Olympus C765UZ.
Let me show what I mean:
This pic is blurred and that's why I chose it: the dot is sharp and not blurred, unlike everything else on the pic. The dot is on the pavement, below the right end of the wall. You'll need to zoom to at least 100% to see it.
Here the dot is hanging in the sky.
And to get back to aviation:
Here the dot is black!!!!
My question: is my CCD sensor damaged? If yes, how did this happen? And can it be repaired?
If no: then what am I seeing?
I've had the camera for 1,5 years now, and I don't know how many pics I have taken, I'd say about 10.000. What is the lifespan of a digital camera?
Any feedback would be greatly appreciated!
