An image-in-image processor comprises two inputs (1,2) for each television or video image signal, a decimation filter (3) with a CIC filter for decimating data pertaining to one of two image signals and a switch (13) which receives the second image signal and the output signal of the decimation filter (3) and combines them into a combined image signal, whereby a partial area of the second image is replaced by a smaller first image.
