Abstract:
A video signal processing apparatus generates a plurality of subframes from each frame of an input video signal to generate an output video signal having a frame frequency higher than the frame frequency of the input video signal. The output video signal also has a smaller number of tones than the number of tones of the input video signal. The pixel values of pixels corresponding to the plurality of subframes are set in accordance with the input video signal to represent halftones that are difficult to display with the number of the tones of the output video signal. The pixel values of the pixels corresponding to the plurality of subframes are set to yield a maximum distribution of the pixel values in a time axis direction.
