First Claim
Patent Images

1. data reconstruction method comprises step:

  • An input image data is extended to one 4 Value Data, described input image data has the information of an image and the boundary information relevant with described image, described 4 Value Datas have some separately corresponding to a pixel the section, wherein the corresponding section of each 1 pixel of 4 Value Datas can change in the middle of 4 different states, the corresponding pixel of expression that one of all different conditions of the corresponding section of each 1 pixel of wherein said 4 Value Datas are assigned to described boundary information should be one 1 a pixel corresponding blocks of the part on border, and other different conditions of the corresponding section of each 1 pixel of described 4 Value Datas then are assigned to each 1 pixel corresponding blocks of pictorial information and corresponding pixel of expression of boundary information should not be one 1 a pixel corresponding blocks of the part on border;

    The corresponding section of each 1 pixel that detects described 4 Value Datas whether with all different conditions in a predetermined state consistency, determining whether corresponding pixel should be the part on border, and convert the section of described 4 Value Datas in the auxiliary video signal the corresponding section of 1 pixel;

    AndWith the corresponding section of 1 pixel of described auxiliary video signal and the corresponding section of 1 pixel of a main video signal, mixing ratio with the mixed relationship that equals an expectation, be mixed into the corresponding section of 1 pixel of a mixed video signal, thereby on screen, show this mixed video signal.
