on dirait que vous mettez l'appareil photo à une taille plus petite que vous devez capturer:

camera.setMode(160, 120, 12, false); 

C'est de 160 x 120, mais vous avez besoin

camera.setMode(320, 250, 12, false); 

Consultez les documents API pour obtenir une explication détaillée des paramètres de cet appel.
