fcams image browser is awesome.
It's way smoother and faster than default Maemo 5 Images app. Someone should replace default Images app with something like this. Swipe effect, zooming etc. are great!

So when you have used some FCAM related apps, be sure to check processlist after.
As you've discovered each hdrcapture image takes a long while to process in the background. I never got a reply to my question as to whether FCam uses or can use any hardware acceleration but it could certainly use its help as the N900 battery probably won't last long enough to take more than a dozen hdrcapture images. Perhaps an option to delay background processing until the N900 is on AC power would be useful.

is it not possible to view the pictures taken with fcamera? I've installed the fcam drivers, hdrcapture and lowlight but cant see where the viewer is? Thanks.

swipe down to enable auto jpg
hdr pics go in camera, lowlight pics go in images -both as jpg, so should be automatically picked up from gallery

i keep getting notified of an update to the fcam drivers...but can't install it because of a conflict with the 'power users' kernel I also have installed.
Do I understand correctly that any updates to the fcam drivers have to be incorporated into the 'power users' kernel before I can use them? The other option being that I uninstall the power users kernel?

Does it?
I think the answer is yes and no. If you're referring to JPEG creation on the dsp, I don't think they are. There just using Nokia's closed source libjpeg62 and it doesn't have any reference to /lib/dsp/jpegenc_sn.dll64P. But Nokia's closed source libjpeg62 does seem to be using NEON calls to help with the discrete cosine transform (DCT):
jpeg_fdct_ifast_neon
jpeg_idct_4x4_neon
jpeg_idct_ifast_neon
The debian version of libjpeg62 doesn't have these calls.

It's the background processing that appears as though it would benefit the most from hardware acceleration as this seems to be all CPU based - for instance, hdrcapture and lowlight both grind away in the background for sometimes minutes at a time and frankly kills the battery in short order.

Has anyone noticed a slight vignetting effect on pictures taken from fcamera when not in direct sunlight (darker edges, brighter centre)?
I Unplugged my phone from the powercord this morning and notice that it was quite hot, or atleast warmer the usual.
Later today I notes that the battery drained very fast today so I started Conky to see it there was a process that might eating my phone. And yes HDRCapture did 100% CPU most of the time. And suddenly I remember that I used FCAM apps yesterday.
So when you have used some FCAM related apps, be sure to check processlist after.
