| Magnified images can be projected onto a large
monitor, so several people can observe and discuss
the target images simultaneously. With this method,
urgent analysis by, and discussion among, many
observers is greatly facilitated. In addition,
inexperienced workers can improve their skills by
observing targets along with experienced workers. |

Only one person can view a live image, which
means that a great deal of time is required
for information sharing. Speedy discussion
is not possible, since the target must be
observed one person at a time. |
