ABSTRACT:
`X` shaped filters can be used as a basis for the enhancement of images derived by electronic scanning. However, whilst such filters offer the advantage that the horizontal and vertical edges of the image will be boosted in preference to the edges at 45.degree., they are not suitable for use where a different amount of enhancement is required horizontally and vertically as is the case when scanning an anamorphic film in a telecine. Described herein is a method of image processing in which the symmetry of the detail signal obtained from the `X` filter can be modified by using a supplementary detail signal obtained from a linear filter to compensate for any asymmetry in the horizontal or vertical resolution of the original image.
