Re: How to detect color (Andrew Conway) ---------------------------------------------------------------------- Message: 1 Date: Wed, 29 Nov 2023 12:48:41 +0000 From: Andrew Conway <nal...@gmail.com> To: Motion discussion list <motion-user@lists.sourceforge.net> Subject: Re: [Motion-user] How to detect color Message-ID: <CAJRa=RjOQyAz0=F6L7fJs-ofgPGF=ocjsdjudq1eyqw+tsp...@mail.gmail.com> Content-Type: text/plain; charset="utf-8" With my phone camera, which is pretty good, I need at least a 1 second exposure at fastest iso/gain settings to pick up the aurora. If processing power is available it might well be possible to stack say 100 frames over a few seconds to get the aurora to be prominent enough to detect by some algorithm. Monitoring relative intensities of pixels on different parts of the sky may be the place to start, especially if compared over two or more successive stacked images.
