Abstract:
A method of displaying an image on a display device in a plurality of sub-fields, each sub-field causing the display device to output a respective illumination level, wherein the image includes a plurality of pixels each having a respective intensity value from a set of intensity values, and wherein at least one of these intensity values is generated by a plurality of combinations of the sub-fields, the method comprising the steps:selecting, for a particular pixel, a combination of sub-fields in conformance with its intensity value; and sending a representation of the selected combination to the display device for displaying the particular pixel, characterized in that in said selecting step, the combination of sub-fields for the particular pixel is selected on the basis of the combination of sub-fields selected for at least one other pixel of the image, for minimizing artifacts in the displayed image, and the combination of sub-fields for the particular pixel is selected to contain the same sub-fields as the combination of sub-fields for the at least one other pixel, such to the extent possible and with preference for the sub-field for outputting the highest illumination level.
