Introduction

For new applications or to set the device via ImpactControlCenter we recommend to use the GenICam interface layout as it allows the most flexible access to the device features.

After you've set the interface layout to GenICam (either programmed or using ImpactControlCenter), all GenICam controls of the device are available.

Note: It depends on the device, which controls are supported. To clarify if your device supports a specific control or property, you can use the interactive "Product Comparison" chapter. Just select the wanted property and click on the button "Rebuild Comparison Table".

In ImpactControlCenter, you can see them in "Setting → Base → Camera → GenICam":

Figure 1: ImpactControlCenter - GenICam™ controls (depends on device and FW version)

As you can see, there are some controls with and without the prefix "mv".

"mv" prefix features are unique non-standard features developed by Balluff/MATRIX VISION.
Without "mv" are standard features as known from the Standard Features Naming Convention of GenICam™ properties (SFNC).

All those features are "camera based / device based" features which can also be accessed using the camera with other GenICam / GigE Vision compliant third-party software.

Note: In GigE Vision™ timestamps are denoted in "device ticks" but for Balluff/MATRIX VISION devices this equals microseconds.; Do not mix up the camera based / device based features with the features available in "Setting → Base → Image Processing". Theses features control the Impact Acquire software stack and therefore will introduce additional CPU load.

which can be used to define multiple AOIs (Areas of Interests) in one image.
See also
The use case Working with multiple AOIs (mv Multi Area Mode) shows how this feature works.

Acquisition Control

The "Acquisition Control" contains features like

Feature name (acc. to SFNC)	Property name (acc. to Impact Acquire)	Description
AcquisitionMode	acquisitionMode	Sets the acquisition mode of the device. The different modes configures a device to send exactly one image ("SingleFrame"), exactly the set number of frames ("MultiFrame") or images constantly until an application explicitly stops the acquisition again ("Continuous"). and can be used for asynchronously grabbing and sending image(s). It works with internal and external hardware trigger where the edge is selectable. The external trigger uses ImageRequestTimeout (ms) to time out. The chapter "How To See The First Image" in the "Impact Acquire SDK GUI Applications" manual shows how to acquire images with ImpactControlCenter. The use case Acquiring a number of images shows how to acquire a number of images; also triggered externally.
AcquisitionStart	acquisitionStart	Starts the acquisition of the device.
AcquisitionStop	acquisitionStop	Stops the acquisition of the device at the end of the current Frame.
AcquisitionAbort	acquisitionAbort	Aborts the acquisition immediately.
AcquisitionFrameRate	acquisitionFrameRate	Controls the acquisition rate (in Hertz) at which the frames are captured. Some cameras support a special internal trigger mode that allows more exact frame rates. This feature keeps the frame rate constant to an accuracy of +/-0.005 fps at 200 fps. This is achieved using frames with a length difference of up to 1 us. Please check in the sensor summary if this feature exists for the requested sensor.
TriggerSelector	triggerSelector	Selects the type of trigger to configure. A possible option is mvTimestampReset. The use case about mvTimestampReset is available.
TriggerOverlap[TriggerSelector]	triggerOverlap	Specifies the type trigger overlap permitted with the previous frame. TriggerOverlap is only intended for external trigger (which is usually non-overlapped: i.e. exposure and readout are sequentially). This leads to minimal latency / jitter between trigger and exposure. However, the camera accepts a new trigger (the exposure time earlier) before the end of the transmission of the current image. Maximum frame rate in triggered mode = frame rate of continuous mode This however leads to higher latency / jitter between trigger and exposure. A trigger will be not latched if it occurs before this moment (trigger is accurate in time). See also Principles of overlapped and pipelined trigger.
ExposureMode	exposureMode	Sets the operation mode of the exposure (or shutter).
ExposureTime	exposureTime	Sets the exposure time (in microseconds) when ExposureMode is Timed and ExposureAuto is Off.
ExposureAuto	exposureAuto	Sets the automatic exposure mode when ExposureMode is Timed.
etc.

related to the image acquisition, including the triggering mode.

Additionally, Balluff offers numerous additional features like:

mvShutterMode
which selects the shutter mode of the CMOS sensors like rolling shutter or global shutter.

common desired average grey value (in percent) used for Auto Gain Control (AGC) and Auto Exposure Control (AEC).
mvExposureAutoAOIMode
common AutoControl AOI used for Auto Gain Control (AGC), Auto Exposure Control (AEC) and Auto White Balance (AWB).
mvAcquisitionMemoryMode
Balluff offers three additional acquisition modes which use the internal memory of the camera:
- mvRecord
  which is used to store frames in memory.
- mvPlayback
  which transfers stored frames.
- mvPretrigger
  which stores frames in memory to be transferred after trigger.
  To define the number of frames to acquire before the occurrence of an AcquisitionStart or AcquisitionActive trigger, you can use mvPretriggerFrameCount.
  See also
  The use case Recording sequences with pre-trigger shows how this feature works.
mvAcquisitionMemoryMaxFrameCount
which shows the maximum of frames the internal memory can save.
See also
The use case Working with burst mode buffer lists some maximum frame counts of some camera models.
mvSmearReduction
smear reduction in triggered and non-overlapped mode.
mvSmartFrameRecallEnable
which configures the internal memory to store each frame (thats gets transmitted to the host) in full resolution.
See also
The use case SmartFrameRecall shows how this feature works.

Since
FW Revision 2.40.2546.0
Common properties for AutoExposureControl, AutoGainControl , and AutoWhiteBalance are available via mv Auto Feature Control.

For "Exposure Auto Mode", in ImpactControlCenter just select in "Exposure Auto" "Continuous". Afterwards, you have the possibility to set lower and upper limit, average gray combined with AOI setting:

Figure 2: Acquire Control → Exposure Auto

mvSmartFrameRecallFrameSkipRatio
When set to a value != 0, the smaller frames get thinned out. AOI requests can still be done for all frames.
mvSmartFrameRecallTimestampLookupAccuracy
is needed for the SkipRatio feature since you don't know the timestamps of the internal frames. This value defines the strictness of the timestamp-check for the recalled image (given in us).

Counter And Timer Control

The "Counter And Timer Control" is a powerful feature which Balluff/MATRIX VISION customers already know under the name Hardware Real-Time Controller (HRTC). Balluff/MATRIX VISION cameras provide:

4 counters for counting events or external signals (compare number of triggers vs. number of frames; overtrigger) and
2 timers.

Counter and Timers can be used, for example,

for pulse width modulation (PWM) and
to generate output signals of variable length, depending on conditions in camera.

This achieves complete HRTC functionality which supports following applications:

frame rate by timer
exposure time by timer
pulse width at input

Sequencer Control

Sequencer overview

The purpose of a sequencer is to allow the user of a camera to define a series of feature sets for image acquisition which can consecutively be activated during the acquisition by the camera. Accordingly, the proposed sequence is configured by a list of parameter sets. Each of these sequencer sets contains the settings for a number of camera features. Similar to user sets, the actual settings of the camera are overwritten when one of these sequencer sets is loaded. The order in which the features are applied to the camera depends on the design of the vendor. It is recommended to apply all the image related settings to the camera, before the first frame of this sequence is captured. The sequencer sets can be loaded and saved by selecting them using SequencerSetSelector. The Execution of the sequencer is completely controlled by the device.

(quoted from the GenICam SFNC 2.3)

Configuration of a sequencer set

The index of the adjustable sequencer set is given by the SequencerSetSelector. The number of available sequencer sets is directly given by the range of this feature. The features which are actually part of a sequencer set are defined by the camera manufacturer. These features can be read by SequencerFeatureSelector and activated by SequencerFeatureEnable[SequencerFeatureSelector]. This configuration is the same for all Sequencer Sets. To configure a sequencer set the camera has to be switched into configuration mode by SequencerConfigurationMode. Then the user has to select the desired sequencer set he wants to modify with the SequencerSetSelector. After the user has changed all the needed camera settings it is possible to store all these settings within a selected sequencer set by executing SequencerSetSave[SequencerSetSelector]. The user can also read back these settings by executing SequencerSetLoad[SequencerSetSelector]. To permit a flexible usage, more than one possibility to go from one sequencer set to another can exist. Such a path is selected by SequencerPathSelector[SequencerSetSelector]. Each path and therefore the transition between different sequencer sets is based on a defined trigger and an aimed next sequencer set which is selectable by SequencerSetNext[SequencerSetSelector][SequencerPathSelector]. After the trigger occurs the settings of the next set are active. The trigger is defined by the features SequencerTriggerSource[SequencerSetSelector][SequencerPathSelector] and SequencerTriggerActivation[SequencerSetSelector][SequencerPathSelector]. The functions of these features are the same as TriggerSource and TriggerActivation. For a flexible sequencer implementation, the SequencerPathSelector[SequencerSetSelector] should be part of the sequencer sets.

LUTSelector	LUTSelector	Selects which LUT to control.
LUTEnable[LUTSelector]	LUTEnable	Activates the selected LUT.
LUTIndex[LUTSelector]	LUTIndex	Controls the index (offset) of the coefficient to access in the selected LUT.
LUTValue[LUTSelector][LUTIndex]	LUTValue	Returns the value at entry LUTIndex of the LUT selected by LUTSelector.
LUTValueAll[LUTSelector]	LUTValueAll	Allows access to all the LUT coefficients with a single read/write operation.
	mvLUTType	Describes which type of LUT is used for the current LUTSelector
	mvLUTInputData	Describes the data the LUT is applied to (e.g bayer, RGB, or gray data)
	mvLUTMapping	Describes the LUT mapping (e.g. 10 bit → 12 bit)

related to the look-up table (LUT) control.

The look-up table (LUT) is a part of the signal path in the camera and maps data of the ADC into signal values. The LUT can be used e.g. for:

High precision gamma
Non linear enhancement (e.g. S-Shaped)
Inversion (default)
Negative offset
Threshold
Level windows
Binarization

This saves (approx. 5%) CPU load, works on the fly in the FPGA of camera, is less noisy and there are no missing codes after Gamma stretching.

Three read-only registers describe the LUT that is selected using the LUTSelector register:

mvLUTType

There are two different types of LUTs available in Balluff/MATRIX VISION cameras:

Direct LUTs define a mapping for each possible input value, for example a 12 → 10 bit direct LUT has 2^12 entries and each entry has 10 bit.
Interpolated LUTs do not define a mapping for every possible input value, instead the user defines an output value for equidistant nodes. In between the nodes linear interpolation is used to calculate the correct output value.
Considering a 10 → 10 bit interpolated LUT with 256 nodes (as usually used in Balluff/MATRIX VISION cameras), the user defines a 10 bit output value for 256 equidistant nodes beginning at input value 0, 4, 8, 12, 16 and so on. For input values in between the nodes linear interpolation is used.

mvLUTInputData

This register describes on which data the LUT is applied to:

Bayer means that the LUT is applied to raw Bayer data, thus (depending on the de-Bayer algorithm) a manipulation of one pixel may also affect other pixels in its neighborhood.
Gray means that the LUT is applied to gray data.
RGB means that the LUT is applied to RGB data (i.e. after de-Bayering). Normally this is used to change the luminance on an RGB image and the LUT is applied to all three channels.

mvLUTMapping

This register describes the mapping of the currently selected LUT, e.g "map_10To10" means that a 10 bit input value is mapped to a 10 bit output values whereas "map_12To10" means that a 12 bit input value is mapped to a 10 bit output value.
