Betreff: Dead pixels, lot of them

I have found an official answer from Gopro in Gopro Italy forum

 

https://community.gopro.com/t5/Cameras/HERO-9-Black-Hot-pixels-Dead-pixel-pixel-bruciati-in-ITALIA/m...

 

Basically, they are studying the problem and also indicates that over 800 ISO the problem disappears.

Over 800 iso the stuck pixels blend in because the noise floor gets raised. Raising the ISO to 800 doesnt fix the sensor flaw it just hides it.

Re: Dead pixels, lot of them

I have tested with a blind scenario ISO 400... it is a disaster but is true that with light is not a problem.

 

Impossible to contact Gopro about this problem, Still we didn't find anyone without this problem.

Re: Dead pixels, lot of them

Hello Everyone. Sorry to hear that you are having issues with the camera. A firmware release has been set to fix the issue of the pixels appearing in lower ISO settings. For updates, see https://gopro.com/en/us/news/hero9-black-launch-updates .

Re: Dead pixels, lot of them

Well, they can't dissapear on the higher ISO settings. hot/dead pixels are  physically damaged pixels on the sensor (tho hot pixels are like half damaged, their appereance depends on the sensor temperature, iso and expousure time). The only way to make them invisible is sensor mapping (taking picture with covered lens, it's called dark frame, it's basically making a map of damaged pixels). GoPro could add that option to the firmware, that could help.  Basically every sensor have hot pixels, tho they shouldn't appear on the lowest iso settings and in expousure times used in daylight.
