Decimation
Decimation reduces the number of pixels in y-direction. Decimation can also be used together
with a ROI or MROI. Decimation in y-direction transfers every n-th row only and directly results
in reduced read-out time and higher frame rate respectively.
Decimation Y: Decimation value for y-direction. Example: Value = 4 reads every fourth row
only.
Multi - ROI
The MV-D1280-640 camera can handle up to 16 different regions of interest. 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. The width and the horizontal offset
are specified by X and W settings. The maximum frame rate in MROI mode depends on the
number of rows and columns being read out. Overlapping ROIs are not allowed.
Enable MROI: Enable MROI. If MROI is enabled, the ROI and MROI settings cannot be changed.
MROI_X:
Select one of the MROI settings.
Y:
Y - coordinate of the selected MROI. If Y is set to 1023, this and all further MROI settings will
be ignored.
H:
Height of the selected MROI.
H tot: Shows the sum of all MROIs as the total image height.
