SEMICONDUCTOR TECHNICAL DATA
3.2 Single Frame Rolling Shutter capture mode
This mode of capture refers to non-interlaced or se-
quential row by row scanning of the entire sensor in a
single pass for the purpose of capturing a single frame.
The start of Integration in this mode is triggered by the
SYNC signal. Similar to the CFRS capture mode, Read-
out of each row follows the Integration of that row.
Therefore the Integration of the rows are staggered out
as well due to the Readout of the sequential rows occur-
ring one after the other (see

Rows have been integrated and readout. Once readout
of the entire frame is complete, the sensor awaits a new
SYNC signal before it starts integration and readout of
another frame.

NOTE!! The faster the clock speed , the closer the se-
quential Integration start times are.
