[Bug 262403] New: Adding Support for Aptina Camera Sensors raw image file format

           Summary: Adding Support for Aptina Camera Sensors raw image
                    file format
           Product: digikam
           Version: 1.2.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: RAW files management
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           1.2.0 (using KDE 4.4.5)
OS:                Linux

Hi,
I have a  digital camera using Aptina sensor, with which I take images in raw
format used by Aptina. It's raw file format is 16bit per color channel, 'GRBG'
mode with file extension is *.raw.
This format is very much different that the usual *.NEF, *.CR2, *.SRF,.. raw
formats of popular camera manufacturers.
It has No headers or any other metadata, just plain raw bayer samples. It does
not specify any information about image width, image height, pixel width,etc.
(I have attached one Raw image file of this format)
When I try to use the Tool-> Raw Batch converter, or DNG converter on this raw
file and try to add this *.raw file that I have, it says Camera:Cannot identify
Raw Image
and hence no conversion is possible on this file.
It would help if Digikam can add support for this *.raw format.It can ask the
user to enter image width,height,bits per pixel for this format and then
interpret it accordingly.
Will it be possible to expect support for this type of raw image format?

thanks,
-AD.

Reproducible: Always


Actual Results:  
Camera:Cannot identify Raw Image

Expected Results:  
Would be good if Digikam recognize this format and allow me to convert it to
DNG or some other format.

digiKam use libraw in background to play with RAW files. ther is nor RAW
decoder source code in digiKam core.

For more information, look here : http://www.libraw.org

I CC Alex Tutubalin who is libraw coordinator.

There is no way to support this data format due to lack of header (and other
metadata).

If the user is asked to enter - width, height, bits per pixel, wouldn't it be
possible? Just trying to understand here.

image size and bps is not enough. For postprocessing stage you need:
 1) image size (full size and real image size)
 2) black and white levels (possibly per-channel)
 3) bayer pattern
 4) white balance data
 5) color data.

Generally, it is better to create separate Aptina-sensor to DNG converter, than
use DNG files in every converter.
