Plus patents they've had since 2007. These are trade secrets and SVE is actually like OIS (Optical Image Stabilization) only the desired effect for HDR or Optical Image Stabilization is what they are all after. How they achieve that is the only difference. It all serves to limit crosstalk within CMOS sensors. <br /><br />Sony isn't the only one attempting to come up with a solution for crosstalk with SVE and actually Fraunhofer was first. Fuji, Sony, etc and now Samsung have developed or furthered their own form of SVE (isolated gate array in CMOS pixel matrixs). Samsung's technology isn't just in the process technology of walling off (isolating) pixels though. <br /><br />They also proposed an algorithm that compensates for any other form of leakage or refraction that causes a lack of blacker blacks in pictures taken with this form of SVE methods. Just in case the isolation achieved in the fabrication process fails to take care of other forms of leakage. It's the fabrication Process... of physical gates that's patented... not SVE effects of gating pixels under Samsung ISOCELL Technology!<br /><br />Note: If you could patent everything about making sensors, you'd have monopolies and oligopolies killing innovation. Samsung alone (as seen in this linked report) would own the industry with wafer supply and most fabrication patents alone even in CMOS sensors! ....they aren't #2 in patents and R&D spending next to IBM for nothing you know?<br /><br />Original HDR....

How they manage the CFA? Maybe this is only for 1080p...Anonymousnoreply@blogger.com
