AR0141CS: 1/4-Inch Digital Image Sensor

Subsampling

The AR0141CS supports subsampling. Subsampling allows the sensor to read out a

smaller set of active pixels by either skipping, binning, or summing pixels within the

readout window.

Figure 23:

Horizontal Binning in the AR0141CS Sensor

Horizontal binning is achieved either in the pixel readout or the digital readout. The

sensor will sample the combined 2x adjacent pixels within the same color plane.

Figure 24:

Vertical Row Binning in the AR0141CS Sensor

Vertical row binning is applied in the pixel readout. Row binning can be configured as 2x

rows within the same color plane.

Pixel skipping can be configured up to 2x in both the x-direction and y-direction. Skip-

ping pixels in the x-direction will not reduce the row time. Skipping pixels in the y-direc-

tion will reduce the number of rows from the sensor effectively reducing the frame time.

Skipping will introduce image artifacts from aliasing.

The sensor increments its x and y address based on the x_odd_inc and y_odd_inc value.

The value indicates the addresses that are skipped after each pair of pixels or rows has

been read.
