[Elphel-support] HSV Saturaturation against Value for various exposure times

[DI Andreas Bean]

Andrey,

The experiment was:
I took 20 images at different exposure time.
Then I chose the same pixel in every image and converted it to HSV colorspace. Saturation refers the S value of the HSV color model, color saturation.
Then I plotted the color saturation against the brightness value V of the HSV color model.
The plott shows a gauss curve i.e. low saturation for long and short exposure times and the maximum saturation is medium exposure time.

Unfortuniately I cant add the graph at the moment from my mobile phone. 

Is that behaviour of the color saturation expected?

Andreas,

Can you provide more details about your experiment and show your graphs? What are you calling "saturation" in this context?

Andrey,

Measuring the saturation (for a single pixel) for different exposure times and plotting it against the value shows an almost perfect gauss curve.

Is this based on physics or sensor properties?
