Abstract

A Method of simulation of high-speed digital image display in computer-display windows is disclosed. These images appear to come from a computer program's data and can change from image to image on low-end PCS at speeds that approximate powerful image-display systems.

Off-Line Simulation of High-Speed Image Amount Key-Entry System

      A Method of simulation of high-speed digital image display in
computer-display windows is disclosed.  These images appear to come
from a computer program's data and can change from image to image on
low-end PCS at speeds that approximate powerful image-display
systems.

      Digital images presented in PC displays require large data
files.  When it is desirable to simulate high-speed image display
systems in a standalone PC, availability of storage space and speed
of retrieval of images to be displayed are important factors.
Generally, standalone PCs do not have adequate hard-file storage
capacity, and they are not capable of quickly presenting images.

      The method described in this publication solves these problems
in a simulator through substituting analog images for digital images
and presenting these analog images in painted windows that appear
like the windows of the image-presentation product being simulated.

      The simulator requires PC hardware capable of presenting both
digital and analog displays on the same PC screen.  Fig. 1 shows a
configuration of a PS/2* with an M-Motion video adapter.  Attached to
the M-Motion video adapter's video input is a video disc player,
which is controlled through the PS/2 serial interface port.

      This configuration is capable of displaying digital frames in
VGA resolution and analog frames at the same time.
