Abstract
A watermark embedding method includes the following steps. The input video signal is received by a processing circuit. Grayscale information of a watermark signal is generated by the processing circuit according to a time series data and a predetermined plane. During a dark sate and a bright state in each of a plurality of consecutive periods, phases of the time series data are opposite and integral values of the grayscales of the predetermined plane are the same. The processing circuit embeds the watermark signal into the input video signal to generate an output video signal with the watermark information. The display panel displays an image according to the output video signal.
