ABSTRACT:
A method of preventing the occurrence of false colors produced at the edge of an image of interest when the image is displayed upon being read by a scanner. When image data representing an interpolation target pixel at which image data is missing is produced, the arithmetic mean of pixels (e.g. R.sub.1 and R.sub.5) neighboring the interpolation target pixel on both sides thereof is calculated [(R.sub.1 +R.sub.5)/2] and corrective data .DELTA..sub.3 is added to the data representing the arithmetic mean. This makes it possible to prevent the occurrence of false colors at the edge of the image.
