Page 25: Image Acquisition
Image Acquisition This chapter gives detailed information about the controlling of the image acquisition. It shows how the camera can be triggered or run in free-running mode, and how the frame rate can be conﬁgured. The structure offers a lot of ﬂexibility in the conﬁguration. It follows the GenI- Cam naming convention.
Page 26: Image Acquisition, Frame And Exposure Control Parameters
4 Image Acquisition Acquisition Control The acquisition control block takes care of the acquisition function. The camera can only capture frames, when the acquisition has been started and is active (see Section 4.2 for more information). Frame Control The frame control block takes care of the capturing of one or many frames and burst of frames (see Section 4.3 for more information).
Page 27: Image Acquisition, Frame And Exposure Trigger
4.1 Overview This list shows only an overview of available parameters. The function and usage of them are explained in the following chapters. 4.1.4 Image Acquisition, Frame and Exposure Trigger The camera can run in "free-running" mode, which means that it captures images automatically in full frame rate once the acquisition has been started.

Page 39: Trigger Software
4.6 Acquisition-, Frame- and Exposure-Trigger Conﬁguration Software Signal Pulse A trigger is generated by the software signal pulse, which comes from a common software signal pulse register (see Section 4.7 for more information). Counter Start A trigger signal is generated by the counter start event (see Section 5.1.3 for more information about the counter start event).
Page 40: Trigger Divider
4 Image Acquisition 4.6.5 Trigger Divider The trigger divider speciﬁes a division factor of the incoming trigger pulses. A division factor of 1 processes every incoming trigger. A division factor of 2 processes every second trigger and so 4.6.6 Trigger Delay The trigger delay lets the user specify a delay, that will be applied between the reception of a trigger event and when the trigger becomes active.

A valid trigger signal on the selected trigger source starts the counter, which means, that it counts the predeﬁned number of events from the start value according to the counter start value and duration conﬁguration.
Page 45: Counter Event Source
5.1 Counter Counter Trigger Source Off The state of the counter changes to "trigger wait". The counter reset source can be set to the counter end signal of the same counter. This allows to restart the counter automatically as soon as it arrives its end condition.

Page 57: O Control
I/O Control This chapter shows the structure of the physical input and physical output lines. It describes the signal path and how to conﬁgure it. The I/O control block contains a signal input path and a signal output path. 7.1 Input Signal Path The camera has four physical signal input lines, which come from the input opto-isolator of the camera hardware interface (see Section 14.6) and which are fed into the input signal path of the camera.
Page 58: Output Signal Path
7 I/O Control 7.2 Output Signal Path The camera has three physical signal output line and two LEDs. The physical output lines are connected to the output opto-isolator in the camera hardware interface (see Section 14.6). The output lines, LED0 and LED1 have their own output signal path which is shown in Fig. 7.2. The source can be selected and the selected signal can be invert before it is sent out of the camera.

Page 61: Image Format Control
Image Format Control The focus on the interesting parts of an image can be set by setting the region of interest (ROI) (see Section 9.1). The ROI inﬂuences the image size which leads into an increased frame rate (see Chapter 11 for more information about the available frame rate).
Page 62 9 Image Format Control On the left-hand side an example of ROI is shown and on the right-hand side an example of MROI. It can be readily seen that the resulting image with MROI is smaller than the resulting image with ROI only and the former will result in an increase in image frame rate. R O I .

Page 74: Bad Pixel Correction
12 Pixel Data Processing 12.2 Bad Pixel Correction The Bad Pixel Correction corrects single pixel defects of the image sensor. If a pixel is marked as "bad" (defect) then its value is replaced by the mean of the two neighbouring pixels on the same image row.
Page 75: Storing The Calibration In Permanent Memory
12.3 Column FPN Correction 12.2.3 Storing the calibration in permanent memory After running the calibration procedure (see Section 12.2.2) the calibration values are stored in RAM. When the camera is turned off, their values are lost. To prevent this, the calibration values must be stored in ﬂash memory. This can be done by clicking on the property BadPixelCorrection_SaveToFlash (in category BadPixelCorrection).
Page 76: Storing The Calibration In Permanent Memory
12 Pixel Data Processing Run the command ColCorrection_Update by clicking on the corresponding button. Read the ColCorrection_Busy value which should be 0 after the calibration has ﬁnished. Repeat this step if its value is not 0. If the ColCorrection_Busy value doesn’t show 0 after various tries, check if the camera receive triggers, when the triggered mode is activated.
Page 77: Grey Level Transformation (Lut)
12.5 Grey Level Transformation (LUT) A user-deﬁned value can be subtracted from the gray value in the digital offset block. If digital gain is applied and if the brightness of the image is too big then the interesting part of the output image might be saturated.
