Frame time control
With this register you can set the frame time (in microseconds) and thus control
the sensor frame rate more precisely than with the BytesPerPacket settings.
• The precision of the frame rate depends on the jitter at start of exposure:
see Jitter at start of exposure on page 222.
• The frame rate is affected by both: current shutter time and
BytesPerPacket setting.
• The FRAMETIME_CTRL register doesn’t change the shutter or
BytePerPacket settings.
Note

• A profile save operation automatically disables capturing
of images.
• A profile save or restore operation is an uninterruptable
(atomic) operation. The write response (of the asynchro-
nous write cycle) will be sent after completion of the
operation.
• Restoring a profile will not overwrite other settings than
listed above.
• If a restore operation fails or the specified profile does
not exist, all registers will be overwritten with the hard-
coded factory defaults (profile #0).
• Data written to this register will not be reflected in the
standard memory channel registers.
Note

• The image transport speed depends on the
BytesPerPacket setting only.
• The camera corrects invalid values automatically.
