Special Timing

Programmed External

Response

Triggered Internal

Response

PE_i1

EXPOSURE time expires

during GLOB

Will corrupt next frame

Impossible situation:

EXPOSURE by construction

never finishes during

READOUT or GLOB

PE_s1

EXPOSURE time expires

during READOUT

Will stop READOUT and start

new GLOB

TI_s0

REQ_EXP before last

READOUT of sequence has

started

= PE_i0 or PE_s0

Extend sequence length

TI_s1

REQ_EXP after last

READOUT of sequence has

started

Will start new exposure

immediately, resulting in default

behavior or PE_s1

Will start new exposure (directly

or after delay, see Figure 48)

In summary:

●

Triggered Internal is the more forgiving mode. It adjusts the actual timing and

scheduling of events as needed to always yield complete and correct images.

●

Programmed External mode (and by extend also Full External mode) however directly

responds to external requests at the cost of possibly corrupting or interrupting images

but no missing higher priority exposures.

Control Mode 3: Streaming

Streaming mode is nothing else than Triggered Internal mode with an infinite sequence

length.

After starting the Streaming mode with a rising edge on REQ_EXP, it will keep on generating

a continuous stream of frames forever until stopped explicitly (via sensor reset or HALT

command; see section 7.2.8). As in Triggered Internal mode, the entire frame configuration is

done by register upload.

Next figure shows the state diagram of the Streaming mode.
