Hello Ashok,
IMAQ Vision includes the ability to save image to file.
- See www.ni.com/vision for more details.
When streaming video to disk, the transfer rates over the PCI bus are significantly greater than most other operations, so keep this in mind when running other operations in parrallel on the same computer.
Regarding the compression, the 2 formats I would recommend would be .bmp (no compression) and .png (compression without loss of information).
