9.2 Means for Controlling Image
Acquisition in Standard Mode
For more information about standard mode and legacy mode and how to set them, see Section 9.1
on
page 103 .
This section presents an overview of the elements involved with controlling the acquisition of
images. Reading this section will give you an idea about how these elements fit together and will
make it easier to understand the detailed information in the sections that follow.
Four major elements are involved in controlling the acquisition of images:

Acquisition start and acquisition stop commands and the acquisition mode parameter

The acquisition start trigger

The frame start trigger

Exposure time control
When reading the explanations in the overview and in this entire chapter, keep in mind that the term
"frame" is typically used to mean a single acquired image.
When reading the material in this section, it is helpful to refer to Figure 46 on page 107 and to the
use case diagrams in Section 9.8 on page 144 . These diagrams present the material related to the
acquisition start and stop commands, the acquisition mode, the acquisition start trigger, and the
frame start trigger in a graphical format.
This section assumes that the standard mode is enabled for image acquisition
control.
In principle, this section also applies if the legacy mode is enabled instead.
In this case, however, the following differences must be taken into account:

the acquisition start trigger of the standard mode is not available in the legacy
mode.

the frame start trigger of the standard mode is called "acquisition start trigger"
in the legacy mode.
When the camera is started for the first time after delivery from the factory the
image acquisition control will not be in standard mode but in legacy mode.
Use the legacy mode only if you want to operate the camera together with
previous cameras not featuring the standard mode.
