Descript. :

get_exposure_time()

Get the camera exposure time [s]

get_gain()

Get the camera gain

get_image()

The implementing class should return here the latest_image in raw_format, followed by the width and height of the image

get_raw_image_size()

Must return a two-value list necessary to avoid breaking e.g. ViideoMockup

Set the image encoding. :param cam_encoding: set the encoding type. :type cam_encoding: str

set_exposure_time(exposure_time_value)

Set the camera exposure time [s]

set_gain(gain_value)

Set the camera gain

set_video_live(flag)
