CImCombine:SetAdjustExptime

The SetAdjustExptime method sets the internal bAdjustExptime flag. If this flag is true, the exposure time of the combined image is an appropriately weighted combination of the exposure times of the source images.

Syntax

CImCombine:SetAdjustExptime( bTrue=true )

bTrue is the state of the bAdjustExptime flag. True (the default) causes the exposure time to be adjusted.

Remarks

In photometric measurements, the image flux, or signal per unit time, can be important. When combining images, the flux calibration can be distorted if the signal level is changed without the exposure time be adjusted correspondingly. In such cases, use the current method to adjust the exposure time to compensate for the change in image signal level.
