".<br /><br />They Olympus are selling a "Tool" to Doctors, not "Image Sensors" to Engineers.<br /><br />Here's the PDF Brochure's Webpage: http://www.olympus-global.com/en/news/2015b/nr1509164klaunche.jsp .<br /><br /><br />Call it 'Marketing', call it wrong (as you did); it needs to be in the Audience's language - They want WYSIWYG, and finer color definition.<br /><br /><br />Inside a closed body there is no light, so they use a "4K xenon light" (I sure hope they mean the light source is four Kelvin by that term) to illuminate inside.<br /><br />That Xenon Lamp is not exactly the same color curve as Sunlight (pure white light) but it's as good as is practical.<br /><br />The Sensor is made by Sony, Olympus makes no changes; it works the way it's Spec. Sheets say.<br /><br />The final link in the chain is that Olympus uses a Sony proprietary OptiContrast™ Panel.<br /><br />Since Olympus knows the color curve of the light source, the Sensor, and the Monitor it is THEIR CLAIM that you can use their Equipment to see inside people and view their innards in the REC2020 Color Space - that is what is 'new' and purported to be beneficial to the Doctor (so they'll buy a few of these instead of a competing product).<br /><br />In this case they are 'guaranteeing the Gamut', since they control the light that 'goes in' (pun intended), they control the processing of the Sensor's output, and they can calibrate for the Display that they supply.<br /><br />That's how I read it.Robhttps://www.blogger.com/profile/08222535289392471857noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-89772456722442426232015-09-16T21:06:00.747+03:002015-09-16T21:06:00.747+03:00Color gamuts define display spaces and have nothin...Color gamuts define display spaces and have nothing to do with image sensors. To demonstrate that the sensor can acquire colors that can be accurately transformed into the display space, they need to show a charts of color error at various places in the display space. If this is a prism-based camera, they need to be very careful to pick a set of points that examines the limitations of their specific prism bands.Dave Gilblomhttp://www.avcemporium.comnoreply@blogger.com
