Pero es que creo que el tamaño del sensor del S2 es mayor que el del Nexus 4, ahí debe de estar la diferencia.....
pero despues de estudiarlo, el sensor tiene el mismo tamaño, el problema es que las celdas son mas pequeñas...
Unit Cell Size: 1.12mµ - NEXUS 4
Unit Cell Size: 1.4mµ - SAMSUNG S2
y decidme por qué...pues no lo entiendo...
Si leeis mas abajo vereis algunas de las cuestiones que se planteaban en el foro.

Y según lo que pone del sensor del Nexus 4 en la publicidad del BSI Sony:
"According to these developments, there are now increasing opportunities for shooting high-definition still and moving images with a
cellular phone, including demands for picture quality that exceeds the framework of existing cellular phone camera functionality.
Sony has now developed a product line of 16M-pixel, 13M-pixel and 8M-pixel CMOS image sensors with 1.12 µm unit pixel" *1
,the industry's smallest, and that
provide full HD video imaging (1080 p at 60 or 30 frame/s)∗2
.
∗1: As of October, 2010 (based on Sony's research)
∗2: The IMX091P and
IMX111PQ are under development now (July 2011)
Ideal for Smartphones
IMX081PQ
■ Diagonal 6.52 mm (Type 1/2.8)
16.41M effective pixels
■ Frame rate: 15 frame/s
IMX091PQ
■ Diagonal 5.87 mm (Type 1/3.06)
13.25M effective pixels
■ Frame rate: 15 frame/s
IMX111PQ
■ Diagonal 4.60 mm (Type 1/4.0)
8.17M effective pixels
■
Frame rate: 22.5 frame/s
IMX081PQ,IMX091PQ,IMX111PQ High S/N Ratio and High Picture Quality
Resumiento que tiene el "unit pixel 1.14um" más pequeño y que puede dar video HD a 60 o a 30 fps a 1080p.
