Abstract
The present disclosure provides a watermark embedding method including following steps. Values of predetermined grayscale program are respectively multiplied by a value of time series data to generate grayscale information of a watermark signal. In a first time period and a second time period included in each of continuous cycles, phases of the time series data are opposite and averages values of the predetermined grayscale program are the same, and a sum of the grayscale information of the watermark signal in the first time period and the second time period is zero. The watermark signal is embedded into a first local dimming signal by the processing circuit to generate a second local dimming signal to control light intensities of local dimming zones according to the second local dimming data with the watermark information.
