Not sure how can a 4.81 MP sensor record in 4K (4096 x 2160 = 8.85 MP)...

Just forked out for Z3 Dual after losing hope on an Ultra.
I guess my wife will be getting a really nice second hand dual SIM handset in March/April.
What is it you are after in March or April?

He is speculating on sony releasing an ultra successor at MWC along with the z4. That's what the recent rumor says.

I was re reading the previews sensor data and noticed something different...
the so called Active Pixel Color Sampling...
the description below
APCS
The APCS is a Sony's CMOS image sensor with single pixel color-sampling by moving colour filter on electrified… (...)
It makes all-pixel sampling 3 colours (R, G, B).
What does this mean ?
in normal sensors, there's three sub-pixels for each pixel, these sub-pixels have filters to grap only specific color Red, Green or Blue.
With APCS, each pixel have an electrified filter, which means that the same pixel can be used to have any color.
the thing is, if that sensor still has those sub-pixels, and each has the ability to grap any of those RGB colors, then the effective resolution will be 3 times 4.81MP, which means 14.43MP making it able to handle more than 4K video
The spec. sheet provide some sort of hint
Number of active pixels : 2052 (H) x 2166 (V), 4.44MP
The features list provide another...
Provides High Speed 4K video mode (6144H x 2160V, 240 frames/s)
If you noticed, the Horizontal count in the "Hight Speed 4K video mode" is 6144, while the number of horizontal active pixels is 2052, which means that in High Speed 4K video mode will actually triple the resolution of the active pixels as 2052*3 = 6156.. while in the same time maintaining the Vertical pixel count.
The sensor format is weird also, it's horizontal pixels count is actually less than vertical one, which mean it's not 4:3 or 16:9 as we're used to have, but it's 1:1.0555, this is weird... totally weird. unless we took the Active-Pixel color sampling into account then it will be 2.844:1
My guess, it's a speciality sensor, maybe for scientific applications or just a prototype to have a proof of concept. it's might be a hard for mobile application as it's almost an 1" sensor (23.79mm)

They also think a similar sensor will be used in the Z4 and rated the rumour @ SR4. Anybody who knows about sensors think this will offer noticeably better performance over the current Sony sensor used in the last few flagship devices?

they say it'd introduced between end 2015 and early 2016.. so i think Z4 is far from that.. maybe Z5

It will be an interesting month or 2 to say the least as we get conflicting rumors regarding spec and number of devices set to be unveiled come MWC. By the way is this sensor a similar tech for what HTC have used in the M7 and M8 ?

SR4 for the sensor, not inside the Z4.
Invite's up!
