B. Frame Grabber CardsImage directly supports four frame grabber cards for acquiring images from video sources, such as TV cameras and VCR's: the Data Translation QuickCapture, the Scion LG-3, Scion AG-5, and the Scion VG-5. All allow brightness, contrast and pseudocolor to be adjusted during "live" capture. All allow continuous histogram display and "live" paste, which can be useful for image alignment.The fastest screen refresh rate (about eight frames per second) is achieved on 68040 and Power PC Macs using built-in video. A 16 inch, or larger, monitor is required to see the entire 640x480 frame without panning. Image supports the 768 x 512 resolution available with 50Hz (PAL/CCIR) versions of the cards. It also supports external triggering. All of the Scion cards support software control of analog gain and offset and on-chip integration. The LG-3 features a frame buffer that can be expanded to 64MB using standard Mac SIMMS. The AG-5 supports video rate averaging and integration. The VG 5 is a short NuBus card that will fit in the Quadra 610 and PowerMac 6100.
