Image Sharpness

XverhelstX · May 18, 2011

Hey everyone,

When I take a picture with the camera library in an application and I compare it with a picture taken from the 'camera application' itself, the sharpness is completely different.

I need a good picture where the text is readable. How does this come and how to solve this.

See these pictures:

Thank you,

I can't see the images you've uploaded. I guess that the image resolution is different. Currently the camera library operates the camera with the default parameters.

Looks more like out-of-focus than limited resolution to me. It looks like a close-up shot, perhaps one used a macro setting and the other didn't.

Ok, and how do i take pictures in micro then?

I've no idea, it was a suggestion as to what the difference was.

oh, ok.

I'm now trying to edit the Camera Library a bit to make the picture in Macro and also using the Flashlight.

but I encountered an error that I cannot seem to solve:

B4X:

    public void FlashOn() {
       
       Camera.Parameters params = c.getParameters();
        // setting camera parameters
        params.setFlashMode( Camera.Parameters.[U]FLASH_MODE_ON[/U] );
        c.setParameters(params);
        
    }

In the underlined, i get the following error:

"FLASH_MODE_ON cannot be resolved or is not a field."

I really don't know what to do with it, I searched around, but can't find it.
I'm not sure but it has to be something with import android.R; or smthing.
the only options I receive after Camera.Parameters.: are this and class

note that I do import these:
import android.hardware.Camera;
import android.hardware.Camera.Parameters;

Hi,

The only thing that I can tell you is that I use the Camera without a canvas.
So with the Panel only the quality is the same.

Succes,
Helen.

The FLASH constant is not available in Android 1.6. You will need to reference a higher version of the SDK.
