For an input video signal comprising odd frames and even frames, the step of ordering frames alternates an odd frame with an even frame at the second rate.
The gamma reference voltage selection module sets a common electrode voltage as 0, and turns over the polarity of the gamma reference voltage at an odd frame and an even frame under the control of the polarity turnover signal.
A single frame is grabbed and an absolute difference between the odd field and the even field within that single image frame is determined.
If we group each pair “odd field / even field”, we obtain five interlaced images:
The TS0 of the rest of the frames is therefore available for other functions, such as the transmission of the alarms.
