APPARATUS FOR SAMPLING AND DISPLAYING AN AUXILIARY IMAGE WITH A MAIN IMAGE

摘要

Apparatus for displaying a combined image of an auxiliary image and a main image includes a source of a main image signal and a source of samples representing an auxiliary image signal. A quincunx subsampler is coupled to the auxiliary image sample source. A signal combiner is coupled to the main image signal source and the quincunx subsampler. The sample combiner combines the main image signal and a signal representing the quincunx subsampled samples to generate a signal representing a combined image of the main and auxiliary images.
