Effect of x_odd_inc = 3 on Readout Sequence
Pixel Readout (No Subsampling)
The MT9D014 supports subsampling. Subsampling reduces the amount of data
processed by the analog signal chain in the MT9D014 thereby allowing the frame rate to
be increased. Subsampling is enabled by setting x_odd_inc and/or y_odd_inc. Values of
1 and 3 can be supported. Setting both of these variables to 3 reduces the amount of row
and column data processed. Figure 17 shows a sequence of 8 columns being read out
with x_odd_inc = 3 and y_odd_inc = 1.
x_odd_inc = 1
x_odd_inc = 3
