Access to full resolution camera in j2me

I am trying to capture images on a tall Nokia phone (N95). The phone’s internal camera is very good (4 megapixels), but in j2me it seems to me that I can get a maximum of 1360x1020 images. I mainly used this example http://developers.sun.com/mobility/midp/articles/picture/

What I did started with 640x480 and increased the width and height by 80 and 60, respectively, until it worked out. Line of code:

jpg = mVideoControl.getSnapshot ("encoding = jpeg & quality = 100 & width =" + width + "& height =" + height);

So, two questions: 1. The phone throws an exception when receiving images larger than 1360x1020. 2. Higher resolution images just look like smoothed versions of smaller ones. For example. When I take a 640x480 image and enlarge it in Photoshop, I can’t tell the difference between this and what is supposedly 1360x1020.

Is this a j2me limitation on the phone? If anyone knows a way to get a higher resolution from a j2me application and / or how to access their own camera from another application?

JPEG “quality” (as interpreted by the code) has nothing to do with resolution. Rather, it is related to how the image is compressed. A 640x480 image with 100 quality will be noticeably better than a 50x440x480 image, but will use more storage space.

Try this instead:

jpg = mVideoControl.getSnapshot("encoding=jpeg&quality=100&width=2048&height=1536");
