Abstract:
1. An image display method for displaying a monochromatic image of a predetermined color with a color display device in which a unit pixel is composed of R, G and B cells, comprising the steps of: allotting a corresponding set of R, G and B data to each gradation of the monochromatic image having a larger number of gradations than a total number of gradations of the predetermined color that can be reproduced by each of the R, G and B cells in the color display device, by using sets of R, G and B data for the total number of gradations of the predetermined color and one or two sets of R, G and B data obtained by at least one of: changing only one of three R, G, B data input to the respective R, G and B cells and simultaneously changing only two of the three R, G and B data, when reproduction performance of each of the R, G and B cells in said color display device refers to the total number of gradations of the predetermined color represented by a total number of the sets of R, G and B data that are obtained by simultaneously changing by one the three R, G and B data input to the respective R, G and B cells in order to reproduce the predetermined color; inputting the allotted corresponding set of R, G and B data to each of the R, G and B cells in said color display device; and displaying the monochromatic image having a higher gradation resolution than the reproduction performance of each of the R, G and B cells in said color display device.
