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. So an acquisition can be grouped in N
single frames or N burst of frames.
4.1.2 Structure
The camera contains a block that controls the image acquisition which contains the sub-blocks
for acquisition control, frame control and exposure control. Furthermore there are a controller
blocks of I/O signals, counters, timers and software interface. All of these elements can be
connected through an interconnection, which allows to control the image acquisition by digital
input signals, by counters, by timers and/or software access.
