Acquisition Control

Grab: Displays live digitized video from your video source. If your source is a camera, focus and
adjust the lens aperture for the best exposure. Use a video generator as a video source to acquire
reference images.

Freeze: Stops live grab mode.
The grabbed image can be saved to disk via the File Control • Save control.

Snap: A single video frame is grabbed.

Abort Exits the current grab process immediately. If any video signal problem prevents the freeze
function from ending the grab, click Abort .
General Options
Note: functions grayed out are not supported by acquisition hardware.

Buffer: Select from supported frame buffer counts, size, and types.

Count and Size : Select the number of frame buffers and the image size here.

Type – Contiguous : Frame buffers are allocated in contiguous system memory (single memory
block - no segmentation).

Type – Scatter-Gather : (Preferred) Frame buffers are allocated throughout system memory in
noncontiguous memory (paged pool). Pages are locked in physical memory so a scatter-gather list
can be constructed. This type allows for the allocation of very large size buffers or large buffer
counts.

Type – Off-screen Video : The buffer is allocated in off-screen video memory and uses the
display adapter hardware to perform a fast copy from video memory to video memory.

Type – Overlay : The frame buffer is allocated in video memory where the display adapter overlay
hardware uses color-keying to view the overlay buffer.

Format : Shows frame buffer pixel formats as supported by the hardware and camera files used.
