410 Megapixel camera sensor

Wow, just left a private technology review and was able to see an image sensor that is used to record video at 50x the resolution of 4K video. It takes a special computer to record at a whopping 3.46Gb per second.
Coming to surveillance drones in the near future.
Holy widescreen Batman!

Raw 8k is 2+ gb/sec. I think they meant 34Gb/s or maybe 346.

At a certain point, aren't we already at the point of diminishing returns in the 4k/8k range for human visual perception anyway?
Certainly the focus on getting color and motion correct (both capture and display) should be a bigger priority than packing more and more visual "data" that cannot even be perceived by human senses, right?

But this is an image sensor, not a display. The human senses don't matter here. The reason we build sensors is because the human senses have limitations, even if that limitation is we just can't be everywhere at once.
Imagine you are viewing 8k security footage on your 8k display. It will look perfect, you couldn't imagine needing more pixels... until you zoom in. Then you're looking at 480p on your 8k display because there just isn't any more data there. If the footage was captured with, say, a 410 megapixel sensor, then you could zoom *way* in and still have enough pixels that it looks crisp on your 8k display.

I think for everyday use with TVs, phone cameras, even movie theaters we are just about there. but like korkstand said there are some specialty applications where this would be useful. Like Elon's Mars base staring back at earth.

That's a fair point. Assuming the optics and lighting are sufficient, pixel count would be the limiting factor. (ETA: Of course, at a certain point, data strain would be the next limiting factor - i.e. "How much data do you want? 8 hours? 4 hours? 5 minutes?")

One hour of 8K RedCode Raw 75 amounts to 7.29 TB. That’s 121.5 GB per minute for raw 8K footage
So, 121.8gbpm / 60 seconds = 2.3gbps for 8k RAW.
In this case, with this sensor, the frame rate for that sensor is limited to 6 frames per second at 8 bits data, so the 3.4gbps is accurate.

I have a 1gig/s line with Xfinity, and speed tests show I actually get that speed. My data cap is 1.2Tb. I can download/stream foe about 20 minutes before I hit my monthly cap .
I really don't want to think about 8k streaming.

quote:Your math is off by a factor of 8 since the speed is in bits and the cap is in bytes. But yeah, 160 minutes isn't much when there's still 43,000 minutes left in the month. I really hate data caps.

But I wouldn't worry too much about 8k streaming. Worst case it will need 4X the bandwidth of 4k, so 100mbps tops though probably closer to half that. That'll last you 1600 minutes minimum which still isn't a hell of a lot, especially since multiple people might be watching on different screens, but hopefully by the time 8k is common all these money-hungry ISPs will have their heads on straight.

So break it down for us dummies….
Is this a resolution thing like being able to read a magazine on the ground from an airplane?
