Cycling Mode Constraints with Changing ROIs
The Cycling Preset Mode features support changing ROIs from one preset to the next. An ROI in
this case refers to a single acquisition area which is a subset of the complete image frame.
The initial position and size of the ROIs (i.e., features ROI Offset Y, ROI Height) are setup via the
Image Format category, but may be overriden in the Cycling Preset category.
 During cycling, the image width, the height of each ROI, and the number ROIs remain same
(Width, ROI Height, and ROI Count Vertical, respectively). The only feature that may change
from one preset to the next is the ROI Offset Y feature of each ROI.
 The number of ROIs to be cycled is defined by the ROI Count Vertical value in the Image
Format category, up to a maximum of 8.
 The Multiple ROI Mode in the Image Format category must be set to Active to use cycling
presets with Multiple ROI (Features Activation Selector = Multiple ROI). It will become
unavailable when the Features Activation Mode is set to Active, and will be made available
again only when the Features Activation Mode is set to Off.
 The ROI Offset Y values can be changed for each cycling preset. To do so, the following
features should be set as indicated:
Category Feature Value
Image Format Multiple ROI Mode Active
Cycling Preset Features Activation Selector Multiple ROI
Cycling Preset Features Activation Mode Active
Cycling Preset Cycling Preset Mode Off
 ROIs cannot overlap in a preset. If a change causes an overlap to occur, the ROI Offset Y value
will be automatically adjusted to eliminate it. In the example below, if modifying the Offset Y of
ROI_2 causes an overlap with ROI_3, then the Offset Y value of ROI_3 will be adjusted.
