Region of Interest (ROI)
In this mode the database image dimension parameters are Image Processing\Decode Settings and specify the region or area of the captured image to be processed. The ROI coordinate data is based on the full scale image size. The WOI of the captured image will be configured to cover all the active database ROI settings. In the following example there are three active database setting, with different ROI configurations. Their coordinates are based at point 0,0 of the full scale image (SXGA = 1280 x 1024 or VGA = 640 X 480). The image WOI is not configurable, it is automatically setup by the database, based on the ROI settings.
This feature is intended to be used in conjunction with the "Image Process Looping" feature, to allow processing different regions of a captured image with different Image Processing Decode Settings. In addition, if combined with "Output Filtering" the user can order the output of decoded symbols in a captured image frame by their location in the Field of View.
