CImage:Gain
The Gain method returns the inverse gain of the camera used to acquire the image. The units of the result are not specified but are usually [electrons per ADU].
|
nGain = CImage:Gain() |
where
nGain is a number describing the camera
gain.
On failure,
this method returns 1.0.
Suppose a CImage object I is attached to an image and was acquired with a camera having an inverse gain of 2.1 electrons per ADU. Then
Printf( "Gain = %.2lf e/ADU", I:Gain() )
prints the following:
Gain = 2.10 e/ADU
