METHOD OF AND UNIT FOR DISPLAYING AN IMAGE IN SUB-FIELDS

摘要

An image processing unit (300) for processing an image that is to be displayed in a plurality of sub-fields on a plasma display panel (406) has storage means (304) for storing the set of combinations of sub-fields that are available as intensity levels and selection means (310) for selecting from the storage means a particular combination for a pixel to be displayed. According to the invention, the difference regarding sub-fields between a first one of the combinations representing a first available illumination level and a second one of the combinations representing the next higher illumination level has been limited, the limiting including control such that only a limited number of the sub-fields that are switched on in the first one of the combinations is not switched on in the second one of the combinations.
