Did you try the next code? it is in the PhoneGap API examples: PhoneGap example

var pictureSource;   // picture source
var destinationType; // sets the format of returned value

// Wait for device API libraries to load
//
document.addEventListener("deviceready",onDeviceReady,false);

// device APIs are available
//
function onDeviceReady() {
    pictureSource=navigator.camera.PictureSourceType;
    destinationType=navigator.camera.DestinationType;
}

function take_pic() {
    navigator.camera.getPicture(onPhotoDataSuccess, function(ex) {
        alert("Camera Error!");
    }, { quality : 30, destinationType: destinationType.DATA_URL });
}

I think your problem is that the variable "destinationType" is undefined. Did you initialized it properly?
