The Japan Marine Science and Technology Center (JAMSTEC) has developed,
first to the world, an HDTV underwater camera designed for deep
sea probes (3000m class) equipped with an ultrahigh sensitivity
imaging tube (HARP imaging tube) developed by NHK. In May this year,
JAMSTEC conducted shooting experiments at several locations, including
Sagami Bay. As a result, it became possible to capture unusually
vivid video images of such sea creatures as shrimp, crabs, jellyfish,
and deep sea fish (realistic enough to make viewers feel as if they
were actually looking at nearby creatures through their own mask).
The picture was taken at a depth of approximately 800m.
|During the Sydney Olympics in September
this year, one of our viewers sent us the following comments.
"I recognized again the high quality of Hi-Vision (HDTV) while
watching the broadcast of the synchronized swimming group competition
at the Olympics. It seemed to precisely reproduce the exact performance
of the Olympians, including their swimming suits decorated with
small beads, and the flowing and splashing movement of the water
around the performers as they competed with such beauty." The
viewer added: "Since it happened to be broadcast simultaneously
with Standard TV (SDTV), I clearly recognized the difference in
picture quality between HDTV and SDTV."
This comment reaffirms the importance of the continuous broadcasting
technology development that NHK, as a broadcaster, has been pursuing
in order to deliver programs with enhanced realism.
