I can hardly imagine that this somewhat simplistic representation with reality. It would, yes. for example, mean that a Gainverstärkung, as depicted here is no more values to 255 are achievable even sure what is wrong.
I also think that even the analog signal before the A / W conversion is increased, so the car goes with AGC amplifiers
http://www.elektronikpraxis.vogel.de/themen/hardwareentwicklung/mikrocontrollerprozessoren/articles/34123/, why should not synonymous in the manual-driven discrete levels possible.
Antwort von camworks:
as far as I know, the gain achieved by s.sensor that a higher voltage s.die each cell is created. This is synonymous to higher output voltage, but it is bought by a higher self-noise of the sensors. only in the downstream electronics digital camera and processed.
perhaps wowu to say something, falls precisely into its territory.
Antwort von domain:
That sounds plausible and is more synonymous with reality.
Regardless of which applies to the practice that an automatic Gainverstärkung catastrophic effect. The gain should only be so strong, even as prominent, completely black screen lots happen.
Never be noisy and s.sich picture black bodies occur, artificially on a certain quite unrealistic Gray were raised.
The courage to total black is beautiful pictures, which meet the situation and the mood perfectly reflect.
