11.11.2 Auto Function ROI
The Auto Function Region of Interest (ROI) feature lets you specify a part of the sensor array that
will be used for auto function control.
The settings for the Auto Function ROI feature are not tied to the settings for the Image ROI feature.
For more information about the Image ROI feature, see Section 11.7 on
All dart BCON cameras provide two Auto Function ROIs. For both Auto Function ROIs, you can
specify a separate part of the sensor array.
Each Auto Function ROI serves as the base for specific auto functions:
The pixel data from Auto Function ROI 1 serves as the base for Exposure Auto and Gain
Auto. The Auto Function ROI settings are always identical for both auto functions. This does
not imply, however, that Gain Auto and Exposure Auto must always be used at the same time.
The pixel data from Auto Function ROI 2 serves as the base for Balance White Auto.
These presets are fixed and can't be changed.
The location and size of an Auto Function ROI is defined by declaring an X offset, a Y offset, a width,
and a height. Auto Function ROIs are referenced to the top left corner of the sensor array (column
0, row 0).
For example, suppose that you specify the X offset as 14, the width as 5, the Y offset as 7, and the
height as 6. This sets the following Auto Function ROI:
