Live View -> end with a "normal" Capture

[TilmanBrugger]

Hi Guys,

i am looking for help.
I use libgphoto2. I try to make a live view and a Image Capture in time, at the end. My Problem is between live view and capture. It need round about 2 sec. to shot a picture.
Can everyone help my, how can i implement?

class camera(object):

def __init__(self):
    logging.basicConfig(format='%(levelname)s:%(name)s:%(message)s', level=logging.WARNING)
    gp.check_result(gp.use_python_logging())
    self.camera = gp.check_result(gp.gp_camera_new())
    gp.check_result(gp.gp_camera_init(self.camera))

def get_camera(self):
    return self.kamera

def capture(self):
    bild_path = gp.check_result(gp.gp_camera_capture(self.camera, gp.GP_CAPTURE_IMAGE))

    kamera_file = gp.check_result(
        gp.gp_camera_file_get(self.kamera, bild_path.folder, bild_path.name, gp.GP_FILE_TYPE_NORMAL))
    target = os.path.join('/tmp', bild_path.name)

    gp.check_result(gp.gp_file_save(kamera_file, target))
    # print(str(target))
    return Image.open(target)

def statuscamera(self):
    return True

def startLiveView(self):
    self.camera_file = gp.check_result(gp.gp_camera_capture_preview(self.camera))

    file_data = gp.check_result(gp.gp_file_get_data_and_size(self.camera_file))
    # display image
    data = memoryview(file_data)

    image = Image.open(io.BytesIO(file_data))
    # self.lastPicture=image

    return image

def killStream(self):
    gp.gp_camera_exit(self.camera)

cameraObject = camera()

i=10
while i<1:
cameraObject.startLiveView()
i=i-1
cameraObject.capture()
