As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! I just received a mint++++ M10-P from Leica Store Miami and discovered a line in the photos taken with it. It seems to be intermittent and went away on some photos but came back on others. Before I return it I'd like to know if there's anything I'm overlooking as far as a solution. It's a wonderful camera and I'd sure prefer to keep it, but I obviously can't live with this blue line in my photos.

happymac Posted July 4, 2019 Share #3 Posted July 4, 2019 Seems to be a bad pixel. Contact LCS to map it out. Not a big issue, but you need the help of Leica. Tom 1 Link to post Share on other sites More sharing options...

happymac Posted July 4, 2019 Share #6 Posted July 4, 2019 As far as I know, they will send you an individual firmware batch. All the best! 1 Link to post Share on other sites More sharing options...

LeicaR10 Posted July 5, 2019 Share #9 Posted July 5, 2019 (edited) Sam, I had the exact same problem. The sensor had to be remapped. Not a big deal. I am certain Josh at Leica Store Miami will be more than happy to assist you getting this issue resolved. More than likely he will ask you to send him your above photo file with the issue. Just give him a call on Friday. r/ Mark Edited July 5, 2019 by LeicaR10 1 Link to post Share on other sites More sharing options...

I had my sensor replaced for dead pixel but if it has been line, I was told it can be remapped. Link to post Share on other sites More sharing options...
happymac Posted July 5, 2019 Share #12 Posted July 5, 2019 This is more or less the same. One dead pixel produces an entire dead line. Tom Link to post Share on other sites More sharing options...
jaapv Posted July 5, 2019 Share #13 Posted July 5, 2019 Basically the decision to remap or replace depends on the number of pixels that have to be mapped out. At assembly of the camera each sensor will be tested and mapped. There is a certain tolerance in the number that may be mapped out. If, at a later stage, a remap would bring the sensor out of tolerance, it will be replaced. 2 Link to post Share on other sites More sharing options...

tracyprestige Posted April 10, 2020 Share #16 Posted April 10, 2020 Just wondering, does mapping out the dead pixels or lines affects the images quality even by very little? Since the mapping procedures would ignore the dead pixels and applying the nearby pixels values. Not sure if I states my concerns correctly since English is not my first language. Thanks!!!

It should not make a difference as there is no one-to-one correlation between "sensels" (pixels in the sensor) and pixels in the picture because the de-mosaicing process done in the camera, where it averages the colour of each sensel in a two-by-two square, will simply ignore the dead pixel and provide the average from the other 3 sensels so the result should not be visible.

Does Leica map out the bad "sensel" or the entire row? The uncorrected problem affects an entire row of output. If the "fix" also affects an entire row, it may be noticeable with some subject matter. It would be interesting to examine a .DNG from an unfixed camera with a bad "pixel" to see if it's possible to locate the problem to a specific row and column.

As far as know what tends to happen is an 'cascade' effect so that if one sensel goes bright then its excess voltage spills into the next sensel and swamps that one whose (now) excess voltage spills into the next and swamps it etc, which is what appears as the green line, so if the sensel that's gone bad can be mapped out then the cascade will be stopped too because the neighbouring sensels will return to normal.

Pete. If it’s a hot or stuck pixel it gets the cascading effect. If it’s a dead pixel the whole row is dead. Either way it can be mapped out. Link to post Share on other sites More sharing options...
