Video processing method and device thereof

A video processing method, comprising:

• receiving an input video signal, wherein a single period of the input video signal has a plurality of first input frames and a plurality of second input frames;
• processing the input video signal, so as to generate an output video signal, wherein a single period of the output video signal has a plurality of first output frames and a plurality of second output frames;
• and
• adjusting a brightness of a plurality of preset frames in the output video signal according to a preset average brightness level, wherein the preset average brightness level is set by one of a user or by an automatic setting module, so as to obtain at least one of a black frame or a gray frame.

A video processing device, comprising:

• a receiving module, receiving an input video signal, wherein a single period of the input video signal has a plurality of first input frames and a plurality of second input frames;
• a processing module, processing the input video signal, so as to generate an output video signal, wherein a single period of the output video signal has a plurality of first output frames and a plurality of second output frames;
• a setting module, setting an average brightness of the output video signal;
• and
• an adjusting module, adjusting a brightness of a plurality of preset frames, comprising a portion of the output video signal, according to a preset average brightness level, wherein the preset average brightness level is set by one of a user or by an automatic setting module, so as to obtain at least one of a black frame or a gray frame.
