Table 4.5: Camera specific values for frame time calculations
A calculator for calculating the maximum frame rate is available in the support
area of the Photonfocus website.
4.5.2
Multiple Regions of Interest
The MV-D1024E camera series can handle up to 16 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 ROI is defined by its starting value in y-direction and its height. Every ROI within a MROI
must be of the same width. The maximum frame rate in MROI mode depends on the number
of rows and columns being read out. Overlapping ROIs are allowed. See Section 4.5.1 for
information on the calculation of the maximum frame rate.
