Description
HDR Mode
On / Off
If [Exposure Mode] is set to “Timed”,
On or OFF [HDR Mode]
Exposure Time 10
~
8000000
[Unit:
us]
Determine the exposure time of HDR.
The knee point on HDR operation can be
determined using the exposure time as the
reference
Knee Point 1
10 ~ 120
(Step=1)
[Unit: %]
Set the output level of Knee Point 1.
The following relation must be kept.
[Knee Point 1]
≦
[Knee Point 2]
Knee Point 2
10 ~ 120
(Step=1)
[Unit: %]
Determine the output level of Knee Point
2.
Knee Slope 2
2~ 16
(Step =1)
Set the position of Knee Point 1 based on
the exposure time.
Knee slope 2 value means the dividing
value of the exposure time.
The position of Knee Point 1 has the
following relation:
[Exposure Time Value]
-
([Exposure Time Value]
÷
[Knee Slope 2 Value])
Knee Slope 3
2 ~ 16
(Step =1)
Set the position of Knee Point 2 based on
the exposure time.
Knee slope 3 value means the dividing
value of the exposure time.
The position of Knee Point 2 has the
following relation:
[Exposure Time Value]
-
([Exposure Time Value]
÷
[Knee Slope 3 Value])
The following shows the relation between
Knee Point 1 and Knee Slope 2 and 3.
(1) 2 Knee Points and 3 Knee Slopes
[Knee Slope 2]
≦
[Knee Slope 3]
(2) 1 Knee Point and 2 Knee Slopes
[Knee Slope 2]
>
[Knee Slope 3]
and
[Knee Point1]
>
[Knee Point 2]
(3) No Knee Point and 1 Knee Slope
[HDR Mode] =“Off”

To read the number of Knee points
generated by the setting of [Knee Point 1],
[Knee Point 2], [Knee Slope 2] and [Knee
Slope 3].
