3.2 Single Frame Rolling Shutter capture mode

(SFRS)

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 “Integration Time in SFRS

mode” on page 14). This process continues until all

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.

The waveforms depicting the SFRS output data stream

refer to Figure 8, on page 12

NOTE!! The faster the clock speed , the closer the se-

quential Integration start times are.
