... Калибровка снимка - это удаление из него паразитной информации, которая включает в себя: темновой шум, горячие пиксели, шум считывания (ток смещения), а также тени от пыли на матрице и оптике. Для калибровки снимка нужно подготовить снимки с паразитной, т.е. нежелательной информацией. В первую очередь нам нужно получить мастер-кадр шума считывания (ток смещения), на западе снимок шума считывания называют Bias или Offset . ... Уровень темнового шума сильно зависит от температуры матрицы. ...
