Brighter doesn't necessarily mean more accurate.

Sammy can try , but I don't think it will be a good idea.
P.S thank you thinness race ! you make smartphones "better".

Bigger sensor + Britecell tech (isocell 2.0) + good aperture + OIS = over 90% on dxomark and famed best smartphone camera on the planet.

Smart WDR looks horrible. Apparently no one at Samsung head of overexposure. The image is too bright and washed out. Where "Conventional" has good contrast and proper colors.

What happens if one channel is clipping? What if the color white takes the value of 255 but in reality it's let's say 298 and the color blue and red don't clip? When you will do the math it will result into a different color, which will give the visual result of a Green or Magenta tinted area. I don't like the idea.

Traditionally at each green cell ... moreThanks guys, this is what I figured.
Still I (as a consumer) will need to proof this is indeed better than traditional "photon" capture.
Colors ARE made from RGB, so any calculation instead of direct input of those basic colors, makes me sceptical.

Traditionally at each green cell with a value G, you do an extrapolation from the neighbouring cells, to get a R and a B value. (Typically a mean of the closest ones), This way you end up with RGN=(R,G,B)
With this approach you calculate the G from the W and then have RGB=(R,W-R-B,B)
Of course it is a bit more complicated, since the filters are not ideal, so you will need some weight-factors and not just 1.0* on each of them.

Can someone explain how white CCD pixels will work?
The will collect unfiltered brightness "data" and combined with R and B pixels will the G be "calculated"?
I don't get it.
Anybody can (really) explain how this works?

well, shapness is important, but i think 20 mp is ok, in my opinion it will be better to improve the optical image stabilization and the low light sensor.

At least not for xenon of the size that smartphones have (the few that do).

Apple logic. They will use that technology for their own design benefit. Sure they pay for it but nobody cares. As long as it is from Apple it will be good. Like Apple A9 and DDR4 RAM.

At least they improved ISOCELL to BRITECELL. This might be better than Sony sensor but who knows. We need to see real life performance first.

Redmi Note 2 used the technology already. Samsung u can get out from the technology world. Copy other phone.... samsung lack research and development team.... no idea why a big company cannot invented something better....

Actually this could be taken a step further, to replace the standard passing R, G, G, B filters, with filters blocking R, G, B and InfraRed (Ir)?
So the recorded signal would be: (IrGB, IrRB, IrRG, RGB)
