Blurred Image / bad quality on N73 & N95

[ceruault]

Hi all,
I'm trying to take snapshots using MMAPI (JSR 135) on my nokia N95.
I'm using the following code, which seems pretty standard.

mPlayer = Manager.createPlayer("capture://video");
				mPlayer.realize();
				mVideoControl = (VideoControl) mPlayer.getControl("VideoControl");

Item item = (Item)mVideoControl.initDisplayMode(GUIControl.USE_GUI_PRIMITIVE, null);
				item.setLayout(Item.LAYOUT_EXPAND|Item.LAYOUT_VEXPAND);			
				cameraForm.append(item);
				mPlayer.start();	
byte snapshot[]=mVideoControl.getSnapshot("encoding=png&width=800&height=600");

The quality of the resulting image is very poor. It's blurry and very noisy. When i use the camera application of the phone I'm getting much better results.
I've tried using jpeg format and larger resolution ( 1024x768) but the result is always the same, very bad image quality ( see sample snapshot!

I tried my midlet on an N73 and got the same results.
Is there a trick to get better results ? Camera settings ? ( unfortunately, the CamerControl is not supported on the N95, which is a real shame for such a pricy and high end model ! )


Thanks for your help.
Regards.

How about using:
"encoding=jpeg&width=800&height=600";
Any difference?

try reducing the resolution 640x480. That is the resolution I am using on N72 7 N73 and gives reasonably good images. However images taken by the default camera app are always more clearer. I think quality of the images depends on the way the Java APIs are implemented on the handset.
