The detailed vertical timing of each effective image duration is the same as “vertical timing/continuous shutter, no shutter” case.
(Note) Prolonged exposure mode is not able to go with partial scan, draft scan mode.
(Note) Asynchronous shutter operation in prolonged exposure mode is not supported.

(Note) In the draft scan mode, 4 pixel lines out of every 16 pixel lines are read out for all pixels. And image data equivalent of 2
pixel lines as (1

5) ,(10
+
1) are read out, adding up 2 pixel lines together.
(Note) In the draft scan mode, whole image field is read out in 35.7fps frame rate by cutting numbers of scanning lines..
