Strange, because it seems to date from at least 2003.<br /><br />It does describe an "SVE" concept but sure seems like a nuisance to implement with a CCD!Eric R Fossumhttps://www.blogger.com/profile/09740612324630105312noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-15426968843824113292012-06-19T16:29:02.642+03:002012-06-19T16:29:02.642+03:00Check this one out - US #7719573.Check this one out - US #7719573.AAhttps://www.blogger.com/profile/10580745581602088976noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-88911089687822504512012-06-18T19:38:12.852+03:002012-06-18T19:38:12.852+03:00I tried and no success.

But, I don't think it has any advantage except for memory requirements and IP over other older approaches.Eric R Fossumhttps://www.blogger.com/profile/09740612324630105312noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-2341906564533886372012-06-15T19:16:50.609+03:002012-06-15T19:16:50.609+03:00The piece ABOVE, not ABOUT.The piece ABOVE, not ABOUT.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-65820751850059667922012-06-15T19:16:19.662+03:002012-06-15T19:16:19.662+03:00I think you misread the piece about. AltaSens'...I think you misread the piece about. AltaSens' approach is to simultaneously capture long and short exposures using a vertically and horizontally interleaved checkerboard pattern.<br /><br />While each field will experience different amounts of motion blur, at 60 fps that shouldn't be much of an issue.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-91924215730789766012012-06-15T11:10:41.750+03:002012-06-15T11:10:41.750+03:00Dual exposure is problematic for video, movement a...Dual exposure is problematic for video, movement artifacts can appear.<br />I'd rather see more color filters in the array, something like RGBWK or RGBrgb.Anonymousnoreply@blogger.com
