Can someone calculate the pixel size for a 20MP on a 2/3" sensor?


pic size : 5248 х 3936 (Z2)

Sensor size 8.8 х 6.6 mm i.e. 2/3"

1 mm = 1000 microns

8.8 х 1000 = 8800 microns across

8800 / 5248 = 1.6768 or 1.7 microns per pixel

^ that's very good.. should have great dynamic range and lower noise levels overall.

For reference, the 1020 is at 1.1 microns @ 41 million pixels using the same size sensor.

the 808 is at 1.4 microns @ 41mpix on a bigger 10.67 x 8.00 sensor

Both Nokia phones suffer from weak DR and highlight clipping.

I really want that 1" sensor in a phone


Anyway, with all the improvements in sensor technology, theoretically the 2/3" sensor should be able to match the 808 for the most part, which would be amazing since it won't need a "hump" on the back for such a large assembly.

In my opinion, the Tegra k1 seems far more interesting. If for the quad a15 the power usage is what Nvidia claims it is on one of the slides. Though I strongly doubt it is...

Regardless, Denver is super, super interesting and Parker is even more so, though by the time Parker is found in devices, the new Qualcomm architecture will be found on devices too I guess.



Well, I agree about Denver K1, but I had kind of figured that it was DOA. NVidia seems to have thrown up its hands trying to get its SoCs into smartphones, so I just assumed it would continue to be all Qualcomm from here on out.


DOA for smartphones? No integrated modem and no aim for smartphones so I guess you're right. But with the efficiency of Maxwell, maybe there's hope then? EDIT: Now to think about it, Google are releasing a 64 bit OS, surely there'll be a new nexus device this year? Maybe Google will release it when the Denver k1 is ready? Probably a tablet? The quad a15 is found in the tango tablet, so surely there's hope?

Where Nvidia SoCs are exciting is tablets. Like it or not, 4k tablets will be here very soon. That's a lot of pixels to push.

Furthermore, I really, really like where Nvidia is going with the upcoming shield tablet. It brings a new dimension to mobile devices and transfer our usage of our PCs to our mobile devices, a step in the right direction I think.

However, besides PC games on mobile devices, the software isn't there to make much good use of that power. I'm desperately waiting for developers to develop applications with that power in mind for things besides games. Quad 1280x800 panels of four different applications running smoothly? In a year or two, on 4k tablets, quad 1080p running smoothly?

The exciting part is when android begins to run chrome applications. Apple vs Google vs Microsoft vs Ubuntu. The race is on to unify all screens. The Ubuntu Edge was truly before it's time, and I think they should try again in 2015 to get some devices into production. Better yet, Sony buy them and run them separately.

I'm looking to buy a tablet next year, would really love Sony to step up their productivity game though.

And you know how the tablet Z2 is crazily thin and light? Why not make a Max or Pro version with a bigger battery and more built-in storage along with laptop-like accessories? Again, productivity applications are required, I don't know what's taking Sony so long.

Lastly, a Vita phone and tablet? Sony should work with AMD (Nvidia have conflicting interests I guess) and go for it. But more on that later.

Me too!!

Btw for 22MP the exact pixel size would be 1.62 Microns.

^ yeah, it would vary slightly depending on the exact resolution.. I just took the one they used for the Z2 because I am assuming they will stick to that format.

The 1" sensor cameraphone ... we can only dream To be honest I don't even care if it has an even bigger hump, but the market tells a different story so I doubt that we will see it happen.

I expect them to go into crazy resolutions instead.. we will probably see something in the 80Mpix range before we see a substantial increase in sensor size. The pixel density thing is not over.. something tells me that they will go bellow 1.1 microns very soon.

The curved sensor tech from Sony is very interesting to me, especially if they let Apple have a go at it

This lens talk is hurting my head

Come on, where's all the juicy stuff!

AFAIK Z3X is planned to use this CMOS. But it is not determined. So guys be patient.

Z3X is just a tentative name. The final name will be surely different.

I also heard the CMOS can be perfectly used on a phone of the similar thickness to Z2 without humping.

So... is Z3x the best option for those wanting a Z Ultra successor?

Really hoping it is a well rounded device

I'm hoping the rumors about this 8.9" HTC Nexus tablet are for real. Denver K1, 1600p display, 3+ GB of RAM, HTC build quality, and Nexus? Yes please.

@ milukugiuniu How reliable is your source? I can't understand Chinese but I used google translate on digi-woo and you seemed to say that the design is a lot worse. What did you mean?
@vivftp Did zomg answer?
@hyui and ramu what doyou think about this?

Could Z3X's design the bull eye design maia talked about last year?

P.S. According to Digitimes Xperia E2 will be shipped in 3Q 14 and will have 4.5" screen. http://www.digitimes.com/news/a20140718PB203.html

^
Yea I thought the same. Is it the same design that maia told us before? Because it kinda looks like it and ramu told us that it will has 2/3 sensor
