Abstract
A method of image data interpolation for obtaining an interlaced image signal by utilizing an image signal of only one field. The method includes the steps of obtaining another field signal by directly utilizing a given field signal or by employing a mean value interpolation processing at a portion of an image where a luminance of the image does not change in the vertical direction, obtaining another field signal by employing the mean value interpolation processing at a portion where a luminance of an image changes singularly to the vertical directions, and obtaining another field signal by directly utilizing a given field signal at some point of a portion where a luminance of an image changes a number of times in the vertical direction.
