9.8 HDR (High Dynamic Range)
(GO-5000M-USB only)
HDR sensing mode can be set when HDR Mode is set to ON while Exposure Mode is Timed.
The parameters to configure dynamic range are HDR_SLOPE Level 1, Level 2, Level 3 and
Level 4.
The user can select any one of those parameters as required for their application.
In this mode, the timed exposure is used as the reference and the value selected in
HDR_SLOPE will compensate to get an appropriate dynamic range by changing the exposure
time.
Notes:
1.
If the exposure mode is OFF and the HDR** mode is set to ON, the exposure mode is
automatically changed to Timed.
2.
If horizontal binning** and/or vertical binning** are set to ON, the HDR** mode cannot be set.
In this case, the HDR** mode must be set first before H-Binning** and/or V-Binning** are set.
3.
In this mode, exposure overlapped behavior is not available and the frame rate is slower than
the normal operation.
4.
The exposure time value is fixed at the value when HDR** Mode is activated. When the
exposure time is changed, HDR** Mode should be off. Once the exposure time is changed, the
HDR** Mode can be set to ON again.
5.
In this mode, Exposure Auto function is disabled.
