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. Typical camera configurations are included in the chap-
ter "Use Cases" in the Appendix C.
4.1 Overview
The overview shows the major camera elements which are involved in the image acquisition.
The section starts with a description of the vocabulary and terms, which are used to explain the
acquisition related features.
4.1.1 Vocabulary
An acquisition is composed of one or many frames. A frame is a single acquired image which
consists of an exposure time and an image read out. A burst of frame is defined as a capture of
a group of one or many frames within an acquisition. An acquisition can be grouped in N
single frames or N burst of frames.
4.1.2 Structure
The image acquisition is controlled by the three sub-blocks acquisition control, frame control
and exposure control. Furthermore the camera contains controller blocks which take care of
the I/O signals, the counters, the timers, the encoders, the action signals, the software signals
and the user outputs. All of these elements can be connected through an interconnect, which
allows controlling the image acquisition by these elements.
