Abstract:
A method of displaying luminous gradations comprising the steps of:assigning each of a plurality of binary images with a respective weight which corresponds to each image's respective luminous level; anddisplaying in time wise fashion said plurality of binary images;wherein each weight is assigned so that, when said plurality of binary images are rearranged by weight in ascending order, (1) an absolute value of the difference in weight (""primary difference"") between any sequential two of said plurality of binary images is less than or equal to 6%, of a total number of luminous gradations that can be displayed in time wise fashion by superposing said plurality of binary images, and (2) a mean value of an absolute value of said primary differences between said plurality of binary images, which are positioned in a first half among all of said plurality of binary images is smaller than a mean value of an absolute value of said primary differences between said plurality of binary images, which are positioned in a latter half among all of said plurality of binary images.
