How to use auto focus

Comments

 I tried this and at least S60 3rd Edition Feature Pack 1 (Nokia E90) returns null when trying to get FocusControl. This makes pretty much useless the camera from Java as you can't focus.

Hartti: The AMMS implementation on E90 does not support camera controls

Note, that the camera-related AMMS controls (javax.microedition.amms.control.camera package) are partially supported only on Series40 6th edition devices (but only with "capture://image" players)

To check which AMMS packages are implemented on Nokia devices you can check this page on Java ME Developer's Library: AMMS package support

player = Manager.createPlayer("capture://video");
 
player.realize();
 
videoControl = (VideoControl)player.getControl("VideoControl");
 
videoControl.initDisplayMode(VideoControl.USE_DIRECT_VIDEO, <your canvas>);
 
videoControl.setDisplayLocation(0,0);
 
videoControl.setDisplaySize(176,208);
 
snapshotControl = (SnapshotControl)player.getControl("javax.microedition.amms.control.camera.
SnapshotControl");
 
focusControl = (FocusControl)player.getControl("javax.microedition.amms.control.camera.
FocusControl");
 
focusControl.setMacro(true);
 
snapshotControl.start(1);
