I also noticed that 8Mpel sample photo have very bad quality.

I do believe oversampling will be one of the characteristics of future image sensors. The word "pixel" becomes outdated when referring to the number samples taken by an image sensor. I think your comment about megapixels really refers to output image pixels, not necessarily the number of photosites on the sensor.Eric R Fossumhttps://www.blogger.com/profile/09740612324630105312noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-64290909875485459042013-09-25T09:15:13.528+03:002013-09-25T09:15:13.528+03:00I agree, there is no need for more megapixels (exc...I agree, there is no need for more megapixels (except for zoom as Nokia is proposing in Lumia 1025). However, Image quality is key, and even if this array camera brings interesting features, the very low quality of the photos (blur, color artifacts, ...) is definitively killing this technology if Pelican is not able to improve image qualityAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-74918874973642885322013-09-25T00:42:55.197+03:002013-09-25T00:42:55.197+03:00Who needs megapixels.

How much did Foveon go thru? Besides that, the best strategy for getting a lot of money in a later round is to not only excite investors but also have the backing of the peer technical community. If some investor comes to me (or you) and asks about the technology and all I have to say is "I dunno" it is not good. Whereas if the community understands its pros and cons and that understanding is congruent with the company's message, it is one of the green lights required to enable moving forward.<br /><br />That said, using this technology in a smart phone is still an uphill sell. Besides the image quality cost, and energy cost of generating the image, real-time video capture and playback may be difficult. Maybe the 3D capture capability on a smaller scale would be good as a 3rd camera?<br /><br />Anyway, time will tell. Pelican has brought this technology to a high level. All they need now is an early adopter and decent early traction. Hope they have their alpha customer lined up!Eric R Fossumhttps://www.blogger.com/profile/09740612324630105312noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-72480533812766988282013-09-23T11:30:33.063+03:002013-09-23T11:30:33.063+03:00There is blur and ringing artifacts around objects...There is blur and ringing artifacts around objects (e.g. around tea or altoid mints box in PiCamHRImgForFig14a.tif photo) when there is a depth change.
