Abstract

A system and method for forming composite single video images utilizing a video peak storing memory to enable new information to be added on a preselected basis to a then stored image so that the image thereafter displayed is a composite of the stored image and any added information. A single field or frame of television information can be captured and digitally stored in memory with new information being added thereto based on the brightness level of the new information relative to the stored image information so that the resulting display is a composite of the information in memory. In a peak-white mode of operation, preselected information added to the memory includes only few information that is 'whiter' that the stored information (alternately, in a peak-black mode of operation adding of new information to memory is dependent upon whether the new information is 'blacker' than the stored information), with such information being selected through use of video peak storing memory. Either monochrome video signals or encoded color TV signals can be processed and displayed.
