  • 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.

    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).

    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 13.7) and which are fed into the input signal path of the camera.

The physical output lines are connected to the output opto-isolator in the camera hardware interface (see Section 13.7). 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.

    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 10 for more information about the available frame rate).
  • Page 62 9 Image Format Control The individual ROI in a MROI must not overlap and no row should be included in more than one ROI. In the color models, every single ROI should start at an even row and should contain an even number rows to have a correct Bayer pattern in the output image.

The result is then divided by the number of binned pixels. The binning feature will result in images with lower resolution but significantly higher SNR. For instance, 2x2 binning will result in roughly twice the SNR (in bright areas of the image).

    11.10 Frame Combine 11.10 Frame Combine Very high frame rates that are well over 1000 fps can be achieved for small ROIs. Every frame (image) activates an interrupt in the GigE software which will issue a high CPU load or the frame rate can not be handled at all by an overload of interrupts.
  • Page 90 11 Pixel Data Processing FrameCombine_ForceTimeout The transmission of the combined frame is forced by writing to the FrameCombine_ForceTimeout property. When the FrameCombine is finished by a timeout, then the remaining data in the combined frame will be filled with filler data: the first two pixels of every filler row have the values 0xBB (decimal 187) and 0x44 (decimal 68).
