Re: FCam question!

chun0216,

Thanks for trying out FCam.

Unfortunately, the N900 hardware can only provide two formats for output, either RAW or UYVY. UYVY is what FCamera (and the default camera app) uses for...

Re: Stock camera better than FCamera?

FCamera DNGs contain 10 bits per pixel, which is the full bit depth of the sensor.

We've done some investigating on where the blue/yellow color issues are coming from, but don't yet have a...

Re: [Request] Video recording with sensor pixel based zoom

Deaconclgi, we don't have FCam running on an N95 - there were some early experiments done on it, but in the end, there was a strict limit to what you can do to the phone (like no manual exposure...

Re: [Request] Video recording with sensor pixel based zoom

TiagoTiago,

That can work on the image sensor in our F2 prototype (the same sensor the N95 has, incidentally) - it's more flexible in terms of region-of-interest control. The N900 Toshiba sensor...

Re: [Request] Video recording with sensor pixel based zoom

The N900's sensor isn't as flexible as we'd like, for something like this.

It has a set of predefined zoom modes, which are various mixes of on-sensor crop and on-sensor binning. (As an example,...

Re: fCamera and RAW

xtian -

You can just view them in FCamera - it's relatively basic but you do see the whole image on screen. Just swipe up from the viewfinder, in case you weren't aware that you can do that.

Re: [Announce] FCamera 0.1.6

Unfortunately, the OMAP3 processing pipeline gives you two options:

1) RAW data from the sensor. That's what we put in the DNGs. No processing beyond what the sensor itself does (which amounts...

geohsia -

You should use the -u flag with fcamDngUtil:

> fcamDngUtil -u input.dng output.dng

to update a DNG to the latest FCam metadata.

Thanks for noticing the project page mixup. Will fix shortly.

Re: [Announce] FCamera 0.1.6

Do you have 'save as JPEG' enabled? We've seen some phones where the background indexer goes nuts and makes the whole phone chug when you're saving JPEGs all the time.

We uploaded fcamera-0.1.7 to extras-testing on Friday. No new features, just bug fixes to the LED and a few fixes inherited from FCam itself.

Please let us know if anything isn't...

Re: [ANNOUNCE] RAW Viewer 1.2 is out and can manage FCamera .DNGs too!

Strange, our thumbnails are just plain RGB, so they should work in theory. I'll put that on our list of things to investigate.

Re: FCam - a new camera API for the N900

I just promoted fcam-drivers to extras. There's possibly a crash bug in it somewhere, but it might take us a while to track it down - it's very intermittent. We're going to rev fcamera at least once...

Re: fcam & fcamera and HDRcapture Thread (Bugs, Ideas..etc)

FCamera's use of the front LED is clearly conflicting with other uses of it. We didn't run into it here, but clearly other apps, or maybe bluetooth use, are doing similar things to what we...

donaggio, great to hear that you're supporting FCam DNGs.

However, in the latest version of FCam/Fcamera, we do embed a thumbnail in the DNG - it should be in IFD0 as a straight RGB24 image...

Re: FCam - a new camera API for the N900

daperl,

While that works fine for lower resolutions, I don't think it's really feasible for full resolution RAW. 5 MP frames mean you can't run faster than 10 fps, which is a bit too slow for the...

Re: FCam - a new camera API for the N900

Re: A simple intervalometer for the N900 (time-lapse photography)

tpaixao, we're going to release the fixed FCam/fcamera code by the end of the week, with a few other minor improvements as well. Until then, dcraw compatibility is still broken.
