Figure 100:

XY-Subsampling for Color and Mono Sensors

In color mode, only 4 out of 4x4 neighboring pixels are read out. The output data is still Bayer

patterned.

In monochrome mode, only 1 out of 2x2 neighboring pixels is read out.

The amount of pixels per channel mentioned in section 7.6.2, scales accordingly when

combining horizontal subsampling with the readout over a reduced number of data channels.

Row subsampling in window i

COLOR_MODE

[0]

0: Monochrome

1: Color

The sensor supports vertical subsampling (skipping rows), which can be set per window. The

2SUBS rows.

When COLOR_MODE register is set to 1, the rows are grouped per 2 to follow the Bayer

pattern, as illustrated in Figure 102. It is recommended to only use even window sizes in color

mode to keep the Bayer filter pattern intact. ROI0 in the example below demonstrates the

effect of an odd window size.
