  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Any one know about this camera: JVC 3-cmos (3840x2048)
 
The camera concept is 3-cmos, with 3840x2048 per cmos (no pixel shifting), and each cmos is 29x15mm.

Judging by the generic housing, this looks like an early lab bench proof of concept. As for the 9 cables, I'd surmise that its an attempt to divide the image processing over an array of more or less off the shelf HD circuitry, marrying them back together downstream through a customized switcher/ data management system. Victor Co. of Japan (JVC) has some serious engineering talent. If indeed what we're seeing is the fruit of a serious R&D effort from them, I'd say maybe/maybe not. Keep in mind that the management culture in the consumer electronics company would likely want to develop proprietary technology, the likelihood that that technology will make it to market can be slim. What they may be doing is creating evaluation and testing equipment for possible 4K displays or projectors. To further illustrate to uphill battle a large company has to fight to get something like a capture device to market, imagine the moving image market as a pyramid. At the top of the pyramid, the very top point, is the Acquisition sector. This is the cutting edge where the cool sexy tech like RED lives. At the base of the pyramid is the Exhibition sector. This is where the millions of LCD's, Plasmas and Projectors commune with the consumer. What a company like JVC wants is to dominate the largest part of the largest sector. They want to leap-frog Sony to get 2k or 4K home theatres into every household? They could give a rat's ass about Acquisition in the larger view. They're in it, but they're only in it to be able to drive their R&D and offer turnkey systems. You can't be in the consumer electronics industry and ignore Acquisition, but ultimately the money is in Exhibition. But hey, how can you build a 4K display if you don't have any 4K footage to test it with?
 
I don't recall where I read it, but someone had a brief review or opinion of this JVC system from a couple months ago. The opinion basically said it seemed to be nothing more than a testbed for the 4K (3.8K actual) CMOS array. On closer examination, there were several defective pixels or photosites or other image anomalies present in the image. Color reproduction and latitude were poor. It was a very early prototype to be sure.

I will say though that it's cool to see the "big guys" working on moving beyond HD and to be using larger sensor sizes. We all know this is coming and they will be nipping at RED's heels. In the end, I still see RED offering the superior product as I know they will continue to evolve and the modular desgin and pricing structure are revolutionary in their own right and something that Sony, Panasonic and JVC are not going to catch on to anytime soon.

There are defective pixels in practically every high-megapixel camera. They are simply "mapped out" by using data from neighboring pixels. The locations of the pixels to be mapped out are stored in the firmware of each camera. I wholly expect Red to have some defective pixels too, just you won't notice them because they have been mapped out at the factory.

The fact that JVC had defective pixels just means that they haven't turned on or created the mapping stuff for their camera yet. It doesn't really imply anything about image quality if they were to make a production camera out of it.

That's true, Bruce... I suppose I was just trying to paraphrase what I remember from the original report. And, not having seen it for myself, I can only guess as to what this person was actually seeing. I'm inclined to believe that it was indeed not much more than a sensor testbed and a way for JVC to show the industry that they're working on a product of this nature. I'm betting Sony has their own system in development too. After all, they have hinted about it and they already have the projector.
 
Gotcha. I do agree with the main point of your post by the way! Sony and JVC really should have realized that Red was a threat earlier - they should have been demonstrating this a year ago. It's going to be very interesting to see how they respond once Red has been shipping in volume - either they slash their own prices drastically, or they will lose a ton of marketshare...

I think it's great that others are considering 4k cameras because that will make 4k displays happen sooner IMO. But RED will always have the one thing the others could never bring themselves to enable... upgradeability.

Red will be viable forever while the others will collect dust and rust.

If you could have a F900 for $12,000 would you buy that instead of a RED? (Me neither, they can't cut the price enough)

I'm not sure how much marketshare there is to gain or lose in the pro market. The consumer market is probably a bigger money maker for these big guys.
