    framegrabber
  • realtime digitizing in 1/60th of a second - but transferring the image to the Amiga takes several seconds
  • separate PAL and NTSC versions
  • supported NTSC resolutions are 320×200, 384×240 (overscan), 320×400, 640×200, 640×400
  • can digitize in colour (except in 640×400) in 2, 4, 8, 16, 32, 64 (EHB) or 4096 (HAM) colours, in 16 grays or in definable pseudo colours
  • uses its own built-in RAM to digitize
  • external control knobs for intensity (brightness), hue (colour bias) and saturation
  • composite input (RCA connector)
  • connects to the parallel port (Centronics) and between the monitor and the RGB port (2× DB9)
  • external power supply
    FrameGrabber 2.0 software
  • pre-digitizing options:
    • Over Sampling - digitize an image any specified number of times up to 50 and combine them into a composite (gives far better results than a single capture)
    • Multiple Exposure - gives two samples
    • Mirror Image
    • Weighted - modifies the automatic contrasting performed
    • Auto Zone - improves image quality in the center at the expense of the border areas
    • these options can be combined in a variety of ways
  • post-digitizing options include: edge detection, sharpening, averaging, photographic negative
  • slow-scan mode - digitize a still object through the supplied colour wheel with a black and white camera
  • supported file formats:
    • IFF, IFF24, RAW
    • DV21 (DigiView Gold's 21 bit format)
    • Brush (for areas smaller than the screen)
    • Palette (for saving only colour information)
    • LUT (contains information for the pseudo colour option)
    • ANIM

    framegrabber
  • grabs images in 256 gray levels (the original colour capable FrameGrabber can achieve 16 gray levels only) - suitable for capturing 24 bit images in three pass
  • 24 bit colour images can be obtained with three pass digitizing using the supplied colour wheel
  • cannot digitize in realtime - digitization takes 1/30th of a second and transferring the image to the Amiga plus displaying it takes 5 to 25 seconds
  • uses its own built-in RAM to digitize and display 256 gray levels on the Amiga screen (framebuffer)
  • supported resolutions are 320×200, 320×400, 384×240 (overscan), 384×480 (overscan)
  • external control knobs for intensity and black level
  • four composite inputs (RCA connectors) working in two ways:
    • all inputs accept independent video signals, each of which can be either monochrome or colour composite (treated as monochrome) - the active input is selected via software
    • the first three inputs accept colour video as separate red green and blue signals, and the fourth accepts the composite synchronization signal - in tandem with a colour RGB video camera, a colour image can be taken without colour wheel, in three pass
  • connects to the parallel port (Centronics) and between the monitor and the RGB port (2× DB9)
  • external power supply
