I'm programmaing a camera application for a N95 device.

When I do camera.image_sizes(), I only get [[(1024,768),(640,480)]] resolution options.

The picture are taken with the good camera (it's not taken from the small front one).

What's the reason of those restriction ?
How can I take bigger pics ?

import camera
print camera.image_sizes()

I tried that on my N95 too. The largest I could get was 2MP (1600x1200). I don't know why it doesn't work at full resolution.

Wao ! You're lucky !
I just have 1024x768
Your resolution would be much better for my app requirement.

What version of python do you use ?
What type of signature : Freeware, dev, higher ?

I found a post related to the question in Symbian C++ forum.

They've got a solution in C++
But how can we do that in Python ???

Please have a look at this thread:

http://discussion.forum.nokia.com/fo...d.php?t=118149

Switching to landscape mode prior the "camera" import should expose higher resolutions in the "JPEG_Exif" format.

The underlying reason is really the one discussed in this thread:

Hope this helps.

I tried your piece of code, it's better : I have all higher resolutions in camera.image_size(), I can take the picture but I cannot save it!!

Is the JPEG_Exif image in a different format?

I got these error :

'str' object has no attribute 'save'

Here is the code :

import appuifw
appuifw.app.orientation='landscape'
import camera
print camera.image_sizes("JPEG_Exif")
pic = camera.take_photo(mode='JPEG_Exif', size = (1600,1200))
pic.save('c:/data/test_picture.jpg')

Did I write a huge error in these piece of code ?

It returns raw data, just write it to disk:

j=camera.take_photo('JPEG_Exif', (2592, 1944))
file = open("c:\\test4.jpg",'w')
file.write(j)
file.close()

Hope this helps.

Thanks a lot for your great help this is working !

I made a big step forward :-)

BUT I've got then a new problem : The autofocus don't work automatically as I though it was. The quality of picture is not good enough.

Is there a trick to solve this ultimate problem ?
