Abstract:
1. A method for displaying a first image and a second image which at least partially overlap within one combined picture, said method comprising: receiving a first video signal to display the first image within a first active region of the combined picture, the first video signal containing the video information for adjacent pixels of the first image in temporally sequential form; receiving a second video signal to display the second image within a second active area of the combined picture, the second video signal containing the video information for adjacent pixels of the first image in temporally sequential form; generating a third video signal from the first and second video signals to display a third image in an overlap region of the first and second active regions; and for each pixel location within the combined picture, generating an output signal by assigning video information associated with the pixel location from the first video signal to the output signal whenever the pixel location within the combined picture lies within the first active region, and assigning video information from the second video signal to the output signal whenever the pixel location within the combined picture lies within the second active region, and wherein the video information from the third video signal is assigned to the output signal whenever the pixel location of the combined picture lies within the overlap region.
