Abstract:
An apparatus to generate an anti-flickered pixel from a source pixel having a source pixel value in a display memory, the apparatus comprising:a plurality of storage elements to store a sequence of pixels in the display memory, the sequence of pixels including the source pixel; a filter coupled to the plurality of storage elements to filter the sequence of pixels, the filter generating a filtered pixel corresponding to the source pixel; a comparator coupled to the plurality of storage elements to compare the source pixel value with a threshold value, the comparator generating a comparison result; an output selector coupled to the filter and the storage elements to select one of the source and filtered pixels according to the comparison result, the selected one of the source and filtered pixels being the anti-flickered pixel; and a source selector coupled to the plurality of storage elements to select the source pixel by comparing a pair of pixels in the middle of the sequence of pixels.
