  • Patent number: 8508581
    Abstract: A pixel data transformation method that can improve the display quality of a text image in a multi-view autostereoscopic display apparatus is provided. The pixel data transformation method includes following steps. The color values of a first and a second original pixels adjacent to each other are obtained. The first and the second original pixels are replaced respectively with a first and a second pixel arrays according to the color value of the first and the second original pixels. Edge pixels on adjoining sides of the first and the second pixel arrays are combined, wherein a color value of each of the combined pixels is a sum of color values of the two corresponding edge pixels on adjoining sides of the first and the second pixel arrays.

  • Patent number: 7848615
    Abstract: The present invention provides a medium for storing a subtitle data structure of an audio/video program and a method for displaying the same. The subtitle data structure of the audio/video program includes a plurality of character packages and a background image package, wherein each character package further has a header that includes the start and the end of a presenting time stamp (PTS), X-Y coordinates of the character, X length, Y length and a color (or colors) of the character, as well as pixel data for displaying the character. Compared with prior art, using the subtitle data structure of the present invention can considerably save the required medium capacity for storing the subtitle data.

  • Publication number: 20070177814
    Abstract: A method is provided for processing data of a sub-picture of a picture. The method includes: providing an object of the sub-picture, forming a binary bit map of the object, and determining whether the number of bits having a first binary value is greater than the number of bits having a second binary value in the binary bit map. The method further includes: determining whether it is necessary to transform the binary bit map into a transformed binary bit map so that the number of bits having the first binary value is smaller than the number of bits having the second binary value in the transformed binary bit map, and determining a compression rule by determining the most significant two bits of a section of consecutive bits in the binary bit map or the transformed binary bit map.
