Patent

CA 2160477

The invention improves over the prior art by providing a media pipeline with two channels (50, 52) for processing sequences of digital still images. A blender (54) is provided so as to enable simple effects on these two streams of video data such as dissolves, wipes and chrome keys. Complex arbitrary three-dimensional effects and other effects may also be provided using an external interface. Thus, a system for processing sequences of digital still images to provide real-time digital video effects includes first (50) and second (51) channels for communicating first and second sequences of digital still images at a rate for simulating video. A controller directs still images to one of the first and second channels. A blender (54), having a first input connected to die first channel, a second input connected to the second channel, and an output, provides a combination of the first and second sequences of digital still images at a rate for simulating video.
