Multiple image digital processing system
First Claim
1. A multiple picture image manipulation system comprising:
- a plurality of frame storage means for respectively receiving video information related to a plurality of pictures;
means for designating the output priority order of the respective pictures from the respective frame storage means;
means for detecting picture information having the highest priority present for producing a control signal indicating this detected priority; and
selector means controlled by the signal from said detector means for selectively outputting information from the plurality of stored pictures held in said respective frame storage means so as to select from only a single picture designated with the highest priority present where picture overlap occurs to provide a multiple picture image in which one of the said pictures masks another without overlap degradation when displayed.

Abstract
A multiple picture image manipulation system for receiving video information related to a plurality of pictures. A designation control designates the output priority order of the respective pictures. A priority coder detects picture information having the higher priority present for producing a control signal indicating this detected priority, and a selector controlled by this signal outputs information from the plurality of pictures so as to select from only a single picture designated with the higher priority present where picture overlap occurs to provide a multiple picture image in which one of said pictures masks another without overlap degradation when displayed. Additional facilities for cross-fading following a change in the picture priority may also be included which pictures can have an associated border if desired.

9. A method of manipulating a multiple picture image comprising:
-
receiving and storing respective frames of video information related to a plurality of pictures; designating the output priority order of the stored frames from the respective pictures; detecting picture information having the highest priority present for producing a control signal indicating this detected priority; and outputting information from the plurality of stored pictures in dependence on the control signal so as to select from only a single picture designated with the highest priority present where picture overlap occurs to provide a multiple picture image in which one of said pictures masks another without overlap degradation when displayed. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
