8k4k Endoscope Tested in Animal Experiment

SweX · Jan 28, 2014

Video with 8k x 4k resolution (8k video) might be widely adopted in the medical industry earlier than in the broadcasting industry.

In the experiment, an 8k endoscope made by combining a compact 8k camera developed by Hitachi Kokusai Electric Inc, etc and an endoscope manufactured by Shinko Optical Co Ltd was used.

In regard to the first reason, with existing endoscopes whose resolution is equivalent to HD, it is necessary to move the tip of an endoscope considerably close to an internal organ to check its details. As a result, there is an increasing chance of collision between the endoscope and forceps. However, if the endoscope is away from the organ, it is impossible to see its details.

As for the second reason, while HD video is equivalent to an eyesight of 1.06 (approx 20/18.87), 8k video is equivalent to an eyesight of 4.27 (approx 20/4.68 ). As a result, it becomes possible to see the internal structures of blood vessels and the boundaries between cancer tissues and normal tissues that could not be seen before as well as sutures with a diameter of 0.15-0.199, which are difficult to see even with the naked eye.

Referring to the rapid miniaturization of 8k cameras, Chiba said, "They were 80kg in 2002. But the weight was reduced to 40kg in 2004, 20kg in 2010 and 2.5kg in 2013. Also, I heard that their size will be reduced to 1/3 in one or two years."

I'm all for it, use it where it actually has some use. It is pointless to keep trying to make TV and film look "better". Seriously, all it does is allow these vendors to jack up the prices higher. If you honestly believe you need or crave higher resolution in your shows or movies..please do consumers a favor and just go outside. I promise you, that's as "realistic" as you're ever going to get.
