My read on it was that the visor wasn't designed to construct camera-like images. It pipes relatively raw sensor data to Geordie's brain and lets his wetware do the interpretive heavy lifting. The real tech advancement is in the neural interface part, not the sensor part. What gets relayed to the Enterprise in this case has to go through a bunch of processing and filters to produce the false color image seen on the viewscreen, so Picard and co aren't actually seeing as Geordie sees, as that would be like seeing umami or something similarly impossible/nonsensical. They're just seeing a small slice of the total data Geordie sees, with a false-color overlay to make it digestible to normal eyes.clearspira wrote: ↑Sat Jun 01, 2019 7:10 pm And why is the Visor so rubbish? Someone programmed in infrared to X-Ray into this thing, but not a full-colour HD mode? And this isn't just here either, this is the colour scheme they will stick with.
Technically, a tricorder can see anything Geordie can, but it can't interpret it like a living brain can, which is why having Geordie look at something can often yield a better assessment than a tricorder alone. It's like the difference between remote piloting a drone aircraft via instruments, and actually being a bird.
IIRC it is implied in later episodes that tricorder data records can provide a video-equivalent when needed. There was one episode (I think it was the one where Geordie gets mutated into an invisible gecko creature) where they used tricorder records to show a 3D holodeck "video" of an event that happened to an away team.
