4.3.2 ROI configuration
In the MV1-D1312C camera series the following two restrictions have to be respected for the
ROI configuration:
• The minimum width (w) of the ROI is 544 pixels in the MV1-D1312C-160 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-D1312C camera series the allowed ranges for the ROI
settings can be deduced by the following formula:
x
min
= max(0 , 656 + ovl
−
w)
x
max
= min(656 − ovl , 1312 − w)
.
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.

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 4.5).
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.
