Abstract: The present invention discloses a missing pixels interpolating method and an apparatus using the method. The method forms a second image from a first image by interpolating a plurality of pixels constituting the first image with a plurality of first pseudo-pixels in such a way that they neighbor to the pixels diagonally and with a plurality of second pseudo-pixels in such a way that they neighbor to the pixels vertically and horizontally. The method comprises the first process of computing values of the first pseudo-pixels using a first monotonous increasing non-linear function, and the second process of computing values of the second pseudo-pixels using a second monotonous increasing non-linear function.

Abstract: In an image processing method for correcting a target pixel using emphasizing and smoothing components, a microcomputer stores the input image signal into an image memory, and generates the enhancement coefficient k data in the enhancement coefficient table memory using a function with an input/output characteristic whereby the output is a simple increasing value when the input is approximately zero. Using a first difference, which is the difference of the target pixel signal minus the signal of the reference pixel positioned on a first direction, the enhancement coefficient k is obtained by referencing the enhancement coefficient table, and the target pixel is enhanced proportionally to the enhancement coefficient k and the first difference.

Abstract: 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.
