When using a sensor with a four pattern matrix
+---+---+
|1:R|2:G|
+---+---+
|3:G|4:B|
+---+---+
... the green and blue color info of the red pixel 1 are just interpolated
from their neighbours. So even RAW data is not RAW but interpolated?
Or is there any camera that does output its data as it actually is detected?
Are external programs around that can to this interpolation externally - and
possibly better than a current internal algorithm?
RAW *is* RAW sensor data. No interpolation or other processing
done. The "external programs" are called RAW converters and every one of
them does the interpolation. Some better than others.
