A method of temporally and/or spatially randomly dithering, to facilitate converting an input M-bit subpixel signal into an (M-N)-bit subpixel signal, may include spatially and/or temporally randomly generating a dithering mask pattern satisfying a condition that a spatial mean and/or a temporal mean of an image signal before dithering matches a spatial mean and/or a temporal mean of the image signal after dithering, respectively, and converting the M-bit subpixel signal into the (M-N)-bit subpixel signal using the dithering mask pattern. |
