Timestamp
TimeStampFrequency – Uint32 – R/C
Camera clock frequency. Timebase for TimeStampValue.
TimeStampReset – Command
Reset the camera’s time stamp to 0. Not possible while PTP enabled (PtpMode =
Master, or Auto).
TimeStampValueHi – Uint32 – R
Time stamp, upper 32-bit. TimeStampValueHi*2
32
/TimeStampFrequency =
units in seconds.
TimeStampValueLatch – Command
Command. Latch the value of the timestamp on the camera. Both Time-
StampValueHi and TimeStampValueLo are updated with the value read from
the camera.
TimeStampValueLo – Uint32 – R
Time stamp, lower 32-bit. TimeStampValueLo/TimeStampFrequency = units in
seconds.
ImageFormat
ROI
Region of Interest. Defines a rectangular sub-region of the image. Selecting an
ROI that is small can increase the maximum frame rate and reduce the amount
of image data. The following parameters define the size and location of the ROI
sub-region:
Height – Uint32 – R/W
The vertical size of the ROI rectangle.
RegionX – Uint32 – R/W
The X position of the top-left corner of the ROI. RegionX + Width must not
exceed SensorWidth.
Units: Hz
Note

PvAPI users: images returned from the camera are
marked with a timestamp: tPvFrame.TimestampLo/Hi.
This can be useful for determining whether images are
missing from a sequence due to missing trigger events.
Default: 0
Units: Camera clock ticks*2
32
Default: 0 Units: Camera clock ticks
Range: [1 - Camera dependent] Units: rows
Range: [0 - Camera dependent] Units: columns
