Paper Abstract

Image display systems have traditionally been grouped into two different classes of equipment. Simple frame buffers, long used to provide a means of refreshing a monitor, have rarely provided any real computational ability or choices for interfacing. Image processors, the workhorses of image analysis, have had to share memory access with hardware for refreshing a monitor. International Imaging Systems has developed a line of low cost image analysis workstations that offload the monitor refreshing responsibilities from a remote image processor to a local frame buffer and allow the user access to interactive image display and analysis tools. The MIDAS (Monochromatic Image Display and Analysis Station) and IVAS (Image Viewing and Analysis Station) devices provide 1024x1024 pixel frame buffers, embedded MC68000 controllers, graphics controllers with overlay memory, look-up tables for radiometric transformations, plus interfaces to a variety of interactive devices and external buses. The devices can be clustered locally to allow the transfer of imagery between stations, peripheral devices (such as parallel transfer drives), and image processors. External bus adaptors (eg ACR/NEMA) can be added to provide compatability with other manufacturer's equipment in an integrated systems environment.
