Overriding Capture Format
The
Fix Capture Format
section is used for overriding the source capture frame size
and frame rate. You can do this by configuring the UFG-05 hardware to scale the
captured image or by selecting only a pre-defined portion of the incoming frames for
output. The reason for doing this is to optimize the performance of the card by limiting
the amount of data transferred to the PC.
You can have the UFG-05 HW downscale the captured image for saving the PCI bus
bandwidth and PC resources.
You can frame lock to every 2
nd
, 3
rd
or 4
th
frame of the original video input to save PCI
bus bandwidth and ensure a smooth video stream output.
You can limit the captured frame rate to an arbitrary fps value
You can control the image orientation when stored in the PC
You can enable the hardware scaling by selecting the
Override Resolution
check-box
and select the new frame size either from the combo-box. Please use the
Width
and
Height
fields below for custom formats. Please use
Apply
button to save the custom
values. The dimensions selected will be forced for the capture pin even if the host
application requests another format.
