Embodiment Construction

[0029] figure 1 A domain cycle with 6 subfields is schematically shown. The field period 102, also called the frame period, is the period during which a single image or frame is displayed on the display screen. In this example, field period 102 includes 6 subfields denoted 104-114. In a subfield, a cell of the display screen can be switched on to produce a brightness. Each subfield begins with a deletion phase in which all cells' memories are deleted. The next phase in a subfield is the positioning phase, during which the cells that need to be switched on to emit light in this particular subfield are triggered. The third phase following this subfield is called the hold phase, in which a hold pulse is applied to the triggered cell. This causes the cells that have been positioned to emit light during the holding phase. For the arrangement of these stages, see figure 1 , where the time order is from left to right. For example, subfield 108 has an erase phase 116 , an locat...

Abstract

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 a storage (304) for storing the set of combinations of sub-fields that are available as intensity levels, and a selector (310) for selecting, from the storage, a particular combination for a pixel to be displayed. 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, are not switched on in the second one of the combinations.

Description

technical field [0001] The invention relates to a method for displaying an image on a display device during time periods called subfields. Wherein, the display device can generate a corresponding illuminance level in each subfield, and the method includes the following steps: [0002] Generate a set of sub-field combinations, each element in the set represents an available illuminance level, [0003] Selecting a specific subfield combination for the corresponding pixel from the set of subfield combinations according to the brightness value of the pixel in the image, [0004] An expression of the combination of subfields selected for each pixel is sent to the display device in order to display that particular pixel. [0005] The invention also relates to an image processing device for processing an image to be displayed on a display device in time periods called subfields, wherein the display device is capable of generating a Corresponding illuminance levels, the image displ...
