Multiple Regions of Interest
The MV1-D1312(IE/C) camera series can handle up to 512 different regions of interest. This
feature can be used to reduce the image data and increase the frame rate. An application
example for using multiple regions of interest (MROI) is a laser triangulation system with
several laser lines. The multiple ROIs are joined together and form a single image, which is
transferred to the frame grabber.
An individual MROI region is defined by its starting value in y-direction and its height. The
starting value in horizontal direction and the width is the same for all MROI regions and is
defined by the ROI settings. The maximum frame rate in MROI mode depends on the number
of rows and columns being read out. Overlapping ROIs are allowed. See Section 4.3.3 for
information on the calculation of the maximum frame rate.
Fig. 4.22 compares ROI and MROI: the setups (visualized on the image sensor area) are
displayed in the upper half of the drawing. The lower half shows the dimensions of the
resulting image. On the left-hand side an example of ROI is shown and on the right-hand side
an example of MROI. It can be readily seen that resulting image with MROI is smaller than the
resulting image with ROI only and the former will result in an increase in image frame rate.
ROI and MROI not only increase the frame rate but also the amount of data to
be processed is reduced. This increases the performance of your image procesing
system.
