Description
If [Exposure Mode] is set to "Timed",
On or OFF [HDR Mode]
Determine the exposure time of HDR.
[Unit:
The knee point on HDR operation can be
us]
determined using the exposure time as the
reference
Set the output level of Knee Point 1.
[Unit: %]
The following relation must be kept.
[Knee Point 1] ≦ [Knee Point 2]
Determine the output level of Knee Point
[Unit: %]
2.
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])
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].
