4.3.2 ROI configuration
In the MV1-D1312(I) camera series the following two restrictions have to be respected for the
ROI configuration:
• The minimum width (w) of the ROI is camera model dependent, consisting of 288 pixel in
the MV1-D1312(I)-40 camera, of 416 pixel in the MV1-D1312(I)-80 camera, of 544 pixel in
the MV1-D1312(I)-160 camera and of 480 pixel in the MV1-D1312(I)-240 camera.
• The region of interest must overlap a minimum number of pixels centered to the left and
to the right of the vertical middle line of the sensor (ovl).
For any camera model of the MV1-D1312(I) camera series the allowed ranges for the ROI
settings can be deduced by the following formula:
x = max(0, 656 + ovl
min
x = min(656 ovl, 1312
max
where "ovl" is the overlap over the middle line and "w" is the width of the region of interest.
Any ROI settings in x-direction exceeding the minimum ROI width must be mod-
ulo 32.

Table 4.5: Summary of the ROI configuration restrictions for the MV1-D1312(I) camera series indicating the
minimum ROI width (w) and the required number of pixel overlap (ovl) over the sensor middle line
The settings of the region of interest in x-direction are restricted to modulo 32
(see Table 4.6 and Table 4.7).
There are no restrictions for the settings of the region of interest in y-direction.

4.3.3 Calculation of the maximum frame rate

The frame rate mainly depends on the exposure time and readout time. The frame rate is the
inverse of the frame time.
