FCamera is an
open-source camera application for the N900. You can use it as
an alternative to the built-in camera application. It provides
significantly more manual control over capture parameters, and
shoots raw (in the Adobe DNG format). It also includes some
nifty features. It has an automatic HDR mode, which has an HDR
viewfinder that lets you preview the full range to be
captured. It has a "lucky imaging" mode in which it takes a
burst of shots and only saves the sharpest. We've found that
this simple trick lets you handhold exposures of up to half a
FCamera really has two purposes. It a useful camera
application for photographers. It is also a base camera
application that students and hobbyists can modify to experiment
with new photographic techniques. Given the second requirement,
we've tried to be fairly careful about balancing features versus
the impact they have on ease-of-understanding of the source. In
most cases we've favored the simpler source code, which is why
you don't see a lot of custom widgets or fancy icons. That said,
it could always be simpler. We welcome any patches to streamline
and clarify FCamera's source.
binary is in the Maemo extras repository. To install
FCamera on your N900 do the following:
- Load the Application Manager if it isn't already open.
- Select the update button and wait a while.
- Then go to Download->Multimedia, and start typing 'fcamera'.
- FCamera should now be visible. Select it to install it.
- If this is the first time you've installed an FCam application, you will be prompted to reboot your N900. Do so or else FCamera will not run properly.
You can download
the FCamera source through extras, or on
page, or you can check
out the most recent development version using anonymous
subversion like so:
svn checkout https://vcs.maemo.org/svn/fcam/fcamera/trunk ./fcamera
In addition to FCamera, you'll need the underlying FCam API
itself. There are several options for getting it:
- Download FCam.zip from
our downloads page, and
extract it somewhere. This includes examples and
documentation. In the latter case, you'll need to rename
fcamera.local.template.pro to fcamera.local.pro, and
edit it to point it at your FCam directory.
- Check the latest version out of SVN with:
svn checkout https://vcs.maemo.org/svn/fcam/fcam-dev/trunk ./fcam-dev
- Install the fcam-dev Debian package in your
development environment, either from extras, or from
our downloads page.
This will not provide API documentation.
If you are new to N900 development, we recommend you read
the getting started section
to get yourself oriented.
We've prepared a PDF that describes the role of all of the
classes within FCamera, and which files they live in. We hope it
is of use.
