Area of interest (AOI)
The camera’s image sensor has a defined resolution. This indicates the
maximum number of rows and pixels per row that the recorded image may
have.
However, often only a certain section of the entire image is of interest. The
amount of data to be transferred can be decreased by limiting the image to a
section when reading it out from the camera. At a lower vertical resolution the
sensor can be read out faster and thus the frame rate is increased.
While the size of the image read out for most other video formats and modes
is fixed by the IIDC specification, thereby determining the highest possible
frame rate, in Format_7 mode the user can set the upper left corner and width
and height of the section (area of interest = AOI) he is interested in to
determine the size and thus the highest possible frame rate.
Setting the AOI is done in the IMAGE_POSITION and IMAGE_SIZE registers.

Note
The setting of AOIs is supported only in video Format_7.
Note
Pay attention to the increments entering in the UNIT_SIZE_INQ
and UNIT_POSITION_INQ registers when configuring
IMAGE_POSITION and IMAGE_SIZE.
