One-shot command on the bus to start of

exposure

The following sections describe the time response of the camera using a sin-

gle frame (one-shot) command. As set out in the IIDC specification, this is

a software command that causes the camera to record and transmit a single

frame.

The following values apply only when the camera is idle and ready for use.

Full resolution must also be set.

Microcontroller-Sync is an internal signal. It is generated by the microcon-

troller to initiate a trigger. This can either be a direct trigger or a release for

ExSync if the camera is externally triggered.

End of exposure to first packet on the bus

After the exposure, the CCD sensor is read out; some data is written into the

FRAME_BUFFER before being transmitted to the bus.

The time from the end of exposure to the start of transport on the bus is:

710 µs ± 62.5 µs

This time 'jitters' with the cycle time of the bus (125 µs).

Feature Value

One-shot  Microcontroller-Sync ≤ 150 µs (processing time in the

microcontroller)

µC-Sync/ExSync  Integration-Start 8 µs
