Decimation
Decimation reduces the number of pixels in x- and y-direction. Decimation can also be used
together with 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 in x-direction
transfers every pixel of a row, but uses the CameraLink
DVAL
(data valid) signal to indicate
which pixels to mask (see 4.33). Therefore it cannot be used to increase the frame rate.
The MV-D1024E-80 and MV-D1024E-160 cameras do not support decimation in
x-direction.
