Abstract

Apparatus for generating a composite image from a plurality of subsidiary images comprises first stores for storing signals representing at least two subsidiary images. Second stores store at least two arrays of mask data, each array having a mask pixel corresponding to each pixel of the composite image. A control system is responsive to each array of mask data to generate for the pixels of the composite image signals defining a weighted sum of the subsidiary images.
