Yet, I don't see the merit in integrating this technology in the mass CE market: the computational requirements are huge and will grow exponentially with the increase in resolution, (which is currently rather poor). Seems as a gimmick at this point (much like 3D imaging using dual-sensors). What will determine the market adoption is the cost of these sensors. To me it seems that the manufacturing costs of such micro-lenses arrays is very high - much higher than producing the micro-lenses that are placed over pixels in CMOS imagers.<br />The cost vs. the effectiveness seems very high but, as Eric wrote - time will tell...<br /> Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-26479711396158616982012-12-28T08:15:59.840+02:002012-12-28T08:15:59.840+02:0010 mm thick for mobile or tablets sound irrelevant...10 mm thick for mobile or tablets sound irrelevant.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-88634693624653454652012-12-28T08:15:19.860+02:002012-12-28T08:15:19.860+02:001 CM thick for mobile or tablet ?

I also wonder how the processing algorithms will be supported on multiple processors. <br /><br />Also wonder if they process images in realtime for preview and video?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-22112294521188076742012-12-28T00:52:20.697+02:002012-12-28T00:52:20.697+02:00Credit to Toshiba for sticking out their neck.

They were also the first major company to embrace and market CMOS active pixel sensors with PPDs. <br /><br />On the other hand, the images really aren't too good at this time and I am not sure what the value proposition is.
