Here is the working code

    $scope.opencamer= function () {
              var options = {
                quality: 75,
                destinationType: Camera.DestinationType.DATA_URL,
                sourceType: Camera.PictureSourceType.CAMERA,
                allowEdit: true,
                encodingType: Camera.EncodingType.JPEG,
                targetWidth: 300,
                targetHeight: 300,
                popoverOptions: CameraPopoverOptions,
                saveToPhotoAlbum: false
            };

                $cordovaCamera.getPicture(options).then(function (imageURI)                    {
                  $scope.lastPhoto = imageURI;
                 $scope.imgUrl = "data:image/jpeg;base64," + imageURI;     


                }, function (err) {
                    // An error occured. Show a message to the user
                });
            }

send $scope.lastPhoto to your db instead of $scope.imgUrl
