Each mode is selected independently for the X and Y shift
registers. The subsampling mode is configured via the serial
input port of the chip. The Y and X shift registers have some
difference in subsampling modes because of constraints in the
design of the chip.
The baseline full resolution operation mode uses four outputs to
read out the entire image. Four consecutive pixels of a row are
put in parallel on the four parallel outputs.
Subsampling is implemented by a shift register with hard coded
subsample modes. Depending on the selected mode the shift
register skips the required number of pixels when shifting the row
or column pointer.
The X shift register always selects four consecutive columns in
parallel. You can subsample in X by activating one of the modes
wherein a multiple of four consecutive columns are skipped on a
CLK_X pulse. The Y shift register selects a single row. It consec-
utively selects two adjacent rows and then skips a set number of
rows (the number of rows to skip is set in the subsample mode).
This implementation is chosen for easy subsampling of color
images through a 2-channel readout. This way color data from
2x2 pixels is made available in all subsample modes. On
monochrome sensors this is not required, one output can be
used and every second row selected by the Y shift register can
be skipped. This doubles the frame rate. Note that for 2 or 1
channel readout, you can power down the not-used output ampli-
fiers through the SPI shift register.
Rows can also be skipped by extra CLK_Y pulses. You do not
need to apply additional control pulses to rows that are skipped.
This is another way to implement extra subsampling schemes.
For example, to support the 24:1 X shift register mode vertically,
set the Y shift register to the 12:1 mode and given an additional
CLK_Y pulse at the start of each row.
