Abstract:
1. A de-interlace method, comprising: generating a characteristic value of a first line-segment, wherein the characteristic value of the first line segment is the sum of the luminance of a plurality of pixels of the first line segment; generating a characteristic value of a second line-segment, wherein the characteristic value of the second line segment is the sum of the luminance of a plurality of pixels of the second line segment; generating a characteristic difference value according the difference between the characteristic value of the first and second line segments; determining a blending vector based on the characteristic difference value; generating an adaptive tuning de-interlace algorithm according to the blending vector, wherein the blending vector is to determine a weight of a first de-interlace algorithm in the adaptive tuning de-interlace algorithm, and a difference between the blending vector and a constant is to determine a weight of a second de-interlace algorithm in the adaptive tuning de-interlace algorithm; and performing the adaptive tuning de-interlace algorithm to generate a de-interlaced image.
