7.8 High Dynamic Range Mode

In the camera, a high optical dynamic range can be realized by setting the camera to a piece-wise linear
response with up to 3 slopes. This section describes briefly the HDR features. An application note is available for
a more detailed explanation. Contact

[email protected]

to request the application note.

NOTE:

The multi slope can currently only be used in

Timed

and in

TimedTriggerControl

exposure mode.

7.8.1 HDR_Mode

| RW | E |

Off

Disable the HDR mode.

MultiSlope2Slopes

Activate the 2 slopes HDR mode with one node.

MultiSlope3Slopes

Activate the 3 slopes HDR mode with two nodes.

7.8.2 SecondExposureTimeRaw

| R | Invisible* |

Read only

This is for a factory test only it is not accessible for users.

* Some frame grabbers might show features that are marked as invisible

7.8.3 SecondExposureTime

| R | Invisible* |

Read only

This is for a factory test only it is not accessible for users.

* Some frame grabbers might show features that are marked as invisible

7.8.4 MultiSlopeNodeSelector

| RW | E |

1 or 2

Select to edit the MultiSlopeLevel and/or MultiSlopeTime for node 1 or
node 2. See Figure 7-10 for a graphical explanation.

7.8.5 MultiSlopeLevel

| RW | E |

1 to 100%
Increment: 1%

Set the level at which the selected node saturates. The level is set in
percentage of the pixel video level. See Figure 7-10 for a graphical
explanation.

NOTE:

the setting of the second node can’t be smaller than the setting of

the first node.

7.8.6 MultiSlopeTime

| RW | E |

1 to 99%
Increment: 1%

Set the time duration for which the selected node should hold its saturation
level. The time duration is set in a percentage of the integration time. See
Figure 7-10 for a graphical explanation.

NOTE:

the setting of the second node can’t be smaller than the setting of

the first node.

7.8.7 The advantages of using the HDR mode

Basically the multi slope response serves as a white compression, still enabling contrast in parts that else would
be saturated. For high exposures, this ensures contrast in bright part of the scene that would otherwise saturate.
An example of the HDR mode disabled and enabled is shown in Figure 7-11. This example shows clearly that
the multi slope allows for contrast in the lamp which is with a normal linear response saturated.
