Sure, you could use Live! to grab a pic on-the-fly. I dunno about Perfect Vision, though, haven't been out with one. As far as rez lines, they're separate from the number of scanning lines. The NTSC system has exactly 525 scan lines per frame, and that's a fixed value in the States. The number of rez lines refers to how closely sd individial picture details can be before the camera is unable to distinguish them as separate lines. If you've ever seen the "Indian Head" test pattern (also called a wedge chart), you may remember wedges of lines that start out broadly spaced at one end and converge into a closely spaced blur of lines at the other. These are used to measure lines of resolution. There are calibrated points on the wedge (400, 300, 200, etc). When viewing the wedge thru a camera, one looks at the point on the wedge where the individual lines merge into a blur, and the number next to that point corresponds to the camera's (and system's) lines of resolution. Another way to look at it… if a camera only had, say, 10 vertical lines of resolution, a pin-striped suit would appear as a solid color on camera. But if the camera's resolution spec was above the spacing of the pinstripes, they would show as individual stripes on camera. Yep, this gets expensive… and confusing! j
