Abstract:
1. A method for performing aspect ratio transformation comprising: receiving frames of image data from each of one or more input sources, wherein a first set of one or more options is associated with a first of said one or more input sources, said first set including a first input aspect ratio of said first input source; determining, for each frame received from said first input source, a set of control parameters, said determining being performed in accordance with said first input aspect ratio and an output aspect ratio; and performing processing of said each frame in accordance with said set of control parameters, said processing including first processing of a first image from said first input source having said first input aspect ratio to generate a second image having said output aspect ratio, wherein, said first processing includes converting said first image having said first input aspect ratio to said second image having said output aspect ratio if said first input aspect ratio is different from the output aspect ratio, and otherwise, as indicated by said set of control parameters, said first processing does not include performing said converting, and wherein said receiving receives image data from each of a plurality of input sources, wherein a different set of options is specified for each said plurality of input sources, each of said different set of options including an input aspect ratio of said each input source.
