If you mean by numerical camera, a commercial camera, there are several possibilities. If the camera has an analog video output (NTSC, PAL), then an NI analog image acquisition card (1407, 1411 or 1409) can be used. It may be possible to import images to LabVIEW/IMAQ Vision if the camera has a TWAIN driver. Alliance Vision sells a TWAIN driver for LabVIEW/IMAQ Vision. Note, IMAQ Vision is able to retrieve images from file for analysis, so as long as you can store the image on the PC in an acceptable file format (.bmp, .tif, .jpg, .png, .avi), then you will be able to process your images using IMAQ.
