What I got...@ "<i>how should we read this?</i>"<br /><br />What I got out of it was this...<br /><br />The interview was for a digital photography affinity site, so the target audience would be interested in digital cameras and on-line or print sizes up to a full regular page. Okay, maybe poster-size, but not as large as cinema screens or billboards.<br /><br />For this group, Mr. Ng seemed to be suggesting that sensor resolutions are not increasing because there isn't much improvement in displayed images beyond what you get at around 14 Mpixels.<br /><br />The Lytro technology seems to use an inverse discrete Fourier transform of some sort. I don't know the technical details, but if the 2D window is 512 x 512, to get a 1000 x 2000 = 2 Mpixel final image, you might want a (1000 + 512) x (2000 + 512) = 3.8 Mpixel sensor array in order to have actual 512 x 512 pixel data for all the final-image pixels.<br /><br />Likewise, to get 14 Mpixel final image resolution with the Lytro technology you might want a source sensor with a resolution of more than 14 Mpixel.<br /><br />I could be wrong, but that's my current best explanation.CDMhttps://www.blogger.com/profile/16405088162729045793noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-29062650818944345282011-08-23T17:46:51.661+03:002011-08-23T17:46:51.661+03:00how should we read this?
