Basler scout GigE 297

The target average gray value may range from 0 (black) to 255 (white). Note that this range of

numbers applies to 8 bit and to 16 bit (12 bit effective) output modes. Accordingly, also for 16 bit

output modes, black is represented by 0 and white by 255.

You can carry out steps 1 to 7 from within your application software by using the pylon API. The

following code snippets illustrate using the API to set the parameter values:

 Selecting and setting Auto Function AOI1: See the "Auto Function AOI" section above.

 Setting the limits for the Exposure Time Abs parameter value (the set parameter values serve

as examples):

 Setting the target average gray value. A medium gray value is selected as an example:

 Enabling the exposure auto function and selecting, for example, the "continuous" mode of

operation:

// Select the appropriate auto function AOI for luminance statistics

// Currently AutoFunctionAOISelector_AOI1 is predefined to gather

// luminance statistics

// Set position and size of the auto function AOI

Camera.AutoFunctionAOISelector.SetValue( AutoFunctionAOISelector_AOI1 );

Camera.AutoFunctionAOIOffsetX.SetValue( 0 );

Camera.AutoFunctionAOIOffsetY.SetValue( 0 );

Camera.AutoFunctionAOIWidth.SetValue( Camera.AutoFunctionAOIWidth.GetMax() );

Camera.AutoFunctionAOIHeight.SetValue( Camera.AutoFunctionAOIHeight.GetMax() );

// Set exposure time limits for luminance control

Camera.AutoExposureTimeAbsLowerLimit.SetValue( 1000 );

Camera.AutoExposureTimeAbsUpperLimit.SetValue( 1.0E6 );

// Set target value for luminance control. This is always expressed

// by an 8 bit value, regardless of the current pixel format

// i.e. 0 -> black, 255 -> white

Camera.AutoTargetValue.SetValue( 128 );

// Set mode of operation for exposure auto function

Camera.ExposureAuto.SetValue( ExposureAuto_Continuous );

For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide

and API Reference.

You can also use the Basler pylon Viewer application to easily set the parameters.

For general information about auto functions, see Section 12.9 on page 287.

For information about Auto Function AOIs and how to set them, see Section 12.9.1.2 on page 289.

For information about minimum allowed and maximum possible exposure time, see Table 12 in

Section 9.7 on page 141.
