““The oversampling in 1020 is much more advanced than in 808. In 1020, the oversampling is adaptive so that we prioritize the high amount of details in bright light, and we prioritize the low noise in low light.
This means that in bright light our 5MP images have higher sharpness and bit higher noise than 808. On the other hand, in low light our images use similar low noise tech. that we have in 808. The background for this implementation is that the subjective image quality tends to be limited by sharpness in bright light and noise in low light.
While we believe that this is exactly the right thing to do, I have also noticed that it has caused some confusion among the users. Naturally the parameters are fully tunable in future software updates if needed.””
