Window Overlap

Several vertical windows may overlap, although this is only useful in subsampling mode. If the same

row is read multiple times within one frame, it will only contain valid data the first time (destructive read

out).

One possibility is to create an interleaved readout scheme by:

Defining two vertical windows with identical size and SUBS set to 1

Giving START of the second window an offset so it starts at a row skipped by the sub sampling

scheme of the first window

Alternating the respective YWIN_ENA bits between every frame.

Description

XSTART

20-21

[13:0]

Start column of horizontal ROI

KSIZE

23-24

[13:0]

Number of columns read per DATAx_OUT channel.

NR_OUTP

[3:0]

Number of DATAx_OUT channels to be used (per side)

XSUBS

[1:0]

Horizontal subsampling setting

The sensor supports reading out any horizontal region of interest starting at column XSTART and a

width of KSIZE×NR_OUTP×2XSUBS, as long as the following constraints are honored.
