ostatnio na forum dosyc glosno o szumiacych matrycach, hot pixelach itp. pojawily sie nawet tematy z testami poszczegolnych modeli.
wyniki ktore tam podawano czesto byly wysokie , zblizone do tych, ktore wystepowaly w moim aparacie. Poszperalem troche w internecie i oto co znalazlem na oficjalnej stronie olympusa:
-----------------------------------
Sometimes it occurs that some pixels on the CCD are not working properly. These defective pixels, called hot pixels, can slightly influence the image quality. Usually these are identified because they show a different colour in comparison to the surrounding pixels. Due to the construction method of sensors, it is impossible to completely avoid faulty pixels.
Pixel mapping helps prevent faulty pixels from affecting image quality. When you carry out the pixel mapping option via the menu, the camera checks the functionality of each single pixel. By comparing the response with those of the neighbouring pixels, any defects can be recognised. The location of the faulty pixel is stored in memory and the camera automatically compensates for the missing or incorrect information in subsequent exposures.

wniosek jeden - uruchomcie pixel mapping
na moim c-4000 po pixel maping ilosc hotow z tysiecy spadala do kilkunastu.
w instrukcji mozna przeczytaz ze pixel mapping dobrze jest uruchamiac raz do roku.
