The AR coefficients described in the paper are what allow basic modeling of the scale of the noise.

Almost none of the games pictured are actually "doujin" games - they are commercial publishers.
Also, the reason we don't remember PC-98 is because it was never sold in the US (except for the very unpopular APC-III). It was the most popular computer on Japan from late 80s to early 90s and is well remembered there. Being the most popular PC, there is a huge amount of software for it, including huge amounts of office and productivity software, many genres of games, and plenty of Western ports.
I agree. I posted a documentary on actual doujin gamedev in Japan, but it looks like the documentary was removed from Youtube. You can still find it on archive.org though for those that are interested in the scene.
And there similarly was a market for relatively low-budget and/or pornographic and/or copyright-infringing computer games in western markets, it's just that people today find weird old ecchi VNs with anime art more interesting than weird old strip poker games with digitized photos.
I agree. Whilst it's great to see a mention of PC-98 the article views it through a very odd lens, and gets a lot of things confused or even just plain wrong.
You don't need to store two whole independent images. The high quality image can predict from the low quality image, and the low quality image can be a lower resolution, too. It is less efficient than storing one image, but more efficient than storing two independent images.
Digital video tape formats (e.g. DV, HDV) are an example. Other containers that operate in this mode are TS and Ogg (and optionally, MKV). Any sort of live streaming format generally is, too.
Depends on the car. My Bolt battery takes a LONG time to get warm just from driving, even with the battery heater running. You can speed it up a bit with yoyo driving (speed up to use power, then regen brake to dump power back into the battery, repeat as necessary) for about a half hour.
Those were all SPI-alike, or at least run in their SPI mode, including the ones linked. (I also used a Nokia 6100 LCD back in the day, and it was SPI, though with a wider interface option).
This is not a "mirrorless camera sensor", at least how it's meant to be interpreted. While technically mirrorless like all webcams, the sensor is under a quarter of the area of the smallest Sony mirrorless intechangeable-lens cameras.
Came to say basically the same thing. Not to mention they also refer to their F1.8 "Glass" when their own technical specs list the lens elements as plastic.
It's basically a $10 sensor, a $5 mic, $5 of miscellaneous plastic and circuitry, and yet they want $175 for what?
I might have given all their typical startup BS and hyperbole a pass if it was like $79 or something reasonable, but at $175 it just seems like a scam.
That's ridiculous. 48MP should be capable of at least 4K video. Are their yields still not high enough at 4K even if they're charging an order of magnitude more than what the components actually cost?
Also hilarious that they say it's "binned" to 1080p when they're actually only getting the rejects that weren't good enough for 4K! Way to be technically correct, Opal.
Technically Sonys current smallest decent mirrorless is apsc and I guess the 1" family (25mm) rx100 cameras could count as mirrorless if you bend things...and this webcam rocks a sensor half that size.
it's like yeah there's no mirror that flips up to expose the sensor because there's no optical through-the-lens viewfinder either...which is what the mirror was for in the first place...
Seems like a cool idea though, but it seems like it could be done even better: get an iPhone 15 Pro Max sensor and put it behind an actual quality glass lens, then add in the beam-forming mic array stuff and MAKE IT A NORMAL CLASS-COMPLIANT WEBCAM, which unlike the C1, the Tadpole is from what I understand.
Interestingly, the smooth bokeh has become a bit popular and is available with Canon "defocus smoothing" lenses (among other older examples). Rather than varying the aperture size over time, these just have a ND filter with the aperture window function coated on (and also a normal iris - the effect works best at the largest aperture setting).
