They are determined, rather, on human science research that aims to determine the conditions under which video can provide “high presence” that makes the viewer feel as if he or she is actually present in the scene shown. Medical Imaging Consortium (MIC) has studied endoscopic surgeries using 8K imaging technologies since 2013. It was confirmed that an 8K endoscope clearly depicts details that are difficult to see using conventional HDTV (high-definition television) endoscopes, including thin blood vessels, nerves and the borders of body organs. Based on the fundamental research at MIC, we developed the world's first 8K endoscope commercial camera.</p>
