Abstract:
1. A video composition apparatus comprising: I video scaling units each of which is configured to scale an input video image with scaling factors to generate scaled input video images; a video storage unit configured to store the scaled input video images; write requesters, provided so as to be respectively associated with the video scaling units, each of which is configured to generate a write request to request the video storage unit to write the scaled input video images generated by the video scaling units into predetermined regions in the video storage unit; one or more read requesters configured to issue read requests of scaled input video images in the video storage unit on the basis of each of J video layout information pieces each of which prescribes layout of the scaled input video images for one of a plurality of composite video images; a read controller configured to read out scaled input video images from the video storage unit in response to the read requests; J composite video image generators, provided so as to be respectively associated with the J video layout information pieces, each of which is configured to generate one of the composite video images from the scaled video images read out by the read controller correspondingly to one of the video layout information pieces; and a scale designation unit configured to designate a plurality of scaling factors on the basis of the video layout information pieces to each of the video scaling units, wherein each video scaling unit is configured to scale the input video image according to the scaling factors supplied by the scale designation unit to generate scaled input video images, the scale designation unit designates J scaling factors as the plurality of scaling factors, to each of the video scaling units, and each video scaling unit includes J scaling units each of which scales the input video image according to a different one of the J scaling factors designated by the scale designation unit.
