Adaptive interpolation method and apparatus using correlation detection |
摘要 |
An interpolation apparatus for preventing image deterioration caused by correlation detection errors. The apparatus comprises a calculation means for obtaining the arithmetic mean of pixels on the scan lines above and below the line being interpolated, a correlation value detection means for obtaining the correlation value of the pixels, a setting means for outputting the reference value of correlation, a comparison means for outputting a binary signal set, a determination means for determining the interpolation line, and a selection means for selecting and passing the output of the calculation means.
