  • Patent number: 8305403
    Abstract: A method for generating a gamma table is provided. The method is applied to a display, and the display obtains n-bit corrected gray levels [y(1), . . . , y(2m)] from m-bit original gray levels [x(1), . . . , x(2m)] by using the gamma table, wherein m and n are positive integers. The method comprises calculating the corrected gray levels [y(1), . . . , y(2m)] corresponding to the original gray levels [x(1), . . . , x(2m)] according to a gamma curve; and successively calculating differences of two adjacent corrected gray levels (y(i+1)?y(i)) and recording the differences as a plurality of gamma reference values z(i+1) (i=1˜(2m?1)) corresponding to the original gray levels x(i+1), in which the value z(1) corresponding to x(1) is y(1), in order to generate the gamma table.

  • Patent number: 7405767
    Abstract: A video image conversion method is for converting interlaced image into progressive image. The deinterlacing method for the video system is for converting the interlaced image into the progressive image. The method performs an interpolation algorithm based on the pixel value of a reference field. An inter-field estimation on the pixel values is performed by referring to a predetermined value to calculate difference value between specific vicinity pixel value and predetermined value, to obtain a set of pixel values, corresponding to the minimum value of summation of a set of pixel difference values. The pixel value corresponding to the auxiliary field is interpolated. The reference field and the auxiliary filed are also referred as the odd field and the even field, where neither the interlacing order nor the respective correspondence is constrained. The method further detects a still motion, such that the flickering is effectively eliminated in another interpolation mode.
