4.3 Reduction of Image Size
With Photonfocus cameras there are several possibilities to focus on the interesting parts of an
image, thus reducing the data rate and increasing the frame rate. The most commonly used
feature is Region of Interest (ROI).
4.3.1 Region of Interest (ROI)
Both reductions in x- and y-direction result in a higher frame rate.
The bayer pattern arrangement in the image has influence of the ROI and MROI
settings. (see Section 3.4).
The minimum width of the region of interest depends on the model of the MV1-
D1312C camera series. For more details please consult Table 4.4 and Table 4.5.
The minimum width must be positioned symmetrically towards the vertical cen-
ter line of the sensor as shown in Fig. 4.18. A list of possible settings of the ROI
for each camera model is given in Table 4.5.

✎
It is recommended to re-adjust the settings of the shading correction each time
a new region of interest is selected.
