6.3 Framerate and shutter
6.3.1 Setting the framerate, command: AcquisitionFrameRateAbs
Command:
AcquisitionFrameRateAbs
Range:
<xxxxxx> = 1...3b49
hex
Description:
With this command the framerate (unit Hz) in free run mode can be set.
Note: The actual range depends on the current ROI.
6.3.2 Setting the shuttertime, command: ExposureTimeRaw
Command:
ExposureTimeRaw
Range:
<xxxxxx> = 2...F4240
hex
Description:
With this command the shuttertime (unit µS) in free run and sync with
timer mode can be set. Depending on the ROI the minimal and maximal
shuttertime can vary. If maximal value for shuttertime is set, the camera
will expose 1/framerate.
6.3.3 Setting the slopes for dynamic range adjustment, command: MultipleSlope
Command:
MultipleSlope
Range:
MultipleSlopeMode
<n>
= 1...3
(Number of slopes)
MultipleSlopeDualAbs
<xx> = 1...63
hex
(percent)
MultipleSlopeTripleAbs <xx> = 1...63
hex
(percent)
Description:
This command sets the multiple slope function for dynamic range adjust-
ment. Through 2 selectable steps, the camera’s dynamic range adjust-
ment option allows to approach the CMOS sensor’s linear range into a
dynamic range corresponding to the non-linear human eye. Consequently,
Eo
Sens
provides definite image details even in case of extreme dark-light
contrasts, which means an invaluable benefit exceptionally in image pro-
cessing. With 'n'=1 the multiple slopes are deactivated and the frame will
be exposed with the whole shuttertime. With activated slopes the bright
pixels will be reset after <xx>percent of the shuttertime. The dual value
must be smaller than triple. Depending on the mode, ROI and shuttertime
the first slope can eventually not start at 1 percent. Only if valid values are
set the function can be activated.
