ABSTRACT:
A composite video imaging device and related method are provided wherein a first and a second video signal, each of which respresents a plurality of lines of video data, are received and converted into corresponding first and second pixel data signals. The first and second pixel data signals are stored by a first and second storage means at a first and a second frequency, respectively, the loading of the first and second pixel data signals occurring independent of one another to permit the first and second pixel data signals to correspond to first and second video signals with different line and/or frame frequenices. Control means are provided for selecting the first or the second pixel data signal for each pixel to be displayed on a monitor and for delivering each selected pixel data signal to the monitor for display of a resultant composite video image.
