ABSTRACT:
A method and apparatus for rendering an image signal by adding another one color different from an inputted color, to an image signal composed of a predetermined number (for example, RGB) of components, is provided. The method for rendering image signals which represent a predetermined number of colors in an apparatus for rendering an image signal of which pixels have three sub-pixels, comprises (a) receiving a predetermined number of color signals and converting the predetermined number of color signals into four-color signals to be represented in the sub-pixels, (b) selecting two-color signals to be outputted alternatively in every other pixels out of the four-color signals and selecting only one-color signal for each position of a pixel area from the two-color signal, (c) recalculating a level value of the selected one-color signal to be represented in the sub-pixels, and (d) controlling image signals to be represented in the sub-pixels according to the level value of the one-color signal calculated in (c).
