    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.

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 13.6) 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 13.6). 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 59: 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 10 for more information about the available frame rate).
  • Page 60 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 .

Decimation in y-direction transfers every n row only and directly results in reduced read-out time and higher frame rate respectively. Decimation can also be used together with ROI or MROI.
