The most effective noise reduction algorithm for removing salt and pepper noise(hardware fault) is median filter. It's edge-preserving

Look at this example from Wikipedia.org:
The upper right corner looks like a K850i photo while an N95 photo would be the lower left corner.

I highly recommend to apply median filter to noisy(arised from greater ISOs) pictures, using Photoshop. but don't present them here.
Look at these pictures:
"Original image"
"Image with added salt and pepper noise"
"Reconstructed image using median filter"

Nice pic above!!What happens when you put a golf tee in a water fountain 
I could never have taken pictures this good on my n95:
Has reduced the quality a little though uploading them here, as they were too wide

Wow! Amazing clarity! I've NEVER been able to get something like this at night. What settings did you use? |

A very good representation of noise reduction:
Noise reduction on Wikipedia
for those lazy ppl that hesitate to click the link, here is abstract:
"....Images taken with both digital cameras and conventional film cameras will pick up noise from a variety of sources. Many further uses of these images require that the noise will be (partially) removed - for aesthetic purposes as in artistic work or marketing, or for practical purposes such as computer vision. In salt and pepper noise (also known as random noise or independent noise), pixels in the image are vastly different in color from their surrounding pixels. The defining characteristic is that the color of a noisy pixel bears no relation to the color of surrounding pixels. Generally this type of noise will only affect a small number of image pixels. When viewed, the image contains dark and white dots, hence the term salt and pepper noise. Typical sources include flecks of dust on the lens or inside the camera, or with digital cameras, faulty CCD elements. A median filter is an example of a non-linear filter and, if properly designed, is very good at preserving image detail. To run a median filter: 1. consider each pixel in the image 2. sort the neighbouring pixels into order based upon their intensities 3. replace the original value of the pixel with the median value from the list This type of filter is very good at removing salt and pepper noise from an image, and also causes very little blurring of edges, and hence is often used in computer vision applications...."

no it is not a physics lesson.
it is fact!
and yes sadeghi85.. i read that before and the techniqe is similar to what we have learnt on our DSP course in Uni.

check this video....taken in fairly bad indoor light, BUT i used lowlight profile.....
realy good quality for a indoor video.
(now i use low light profile all time when i record...realy BIG different...gets much sharper)...
wait some seconds, then i keep the phone steady ...he he

Well i got tired of my posh living room-lamp and decided to put it where others might enjoy it. What do you think?!
Sorry for the blurry shots.
By the way, i got my phone repaired today since it didn't wont to start. They reflashed it and that was that. They also fixed the small problem with distorted sound when making a call. It was a flake of metal laying int the speaker! So they put a new one in. All this in a couple of hours and no extra charge for doing it so fast! Good service i'd say!

Yes it does. At first i wondered what the hell was wrong with my eyes. It's just hanging there and it's a bit away from the centre of the town so there isn't that many who will notice it.
