Abstract:
1. An image processor for processing a video signal, comprising: aspect ratio information acquisition means for acquiring aspect ratio information about an original video signal by detecting a video identification signal that has been superimposed on the original video signal, wherein the acquired aspect ratio information is a two-bit code indicating a process of aspect ratio conversion on the original video signal; aspect ratio conversion means for carrying out the process of aspect ratio conversion on the original video signal based on the acquired aspect ratio information to generate a processed video signal representing an image of the original video signal having a roundness of 1, wherein the aspect ratio conversion means has an operation mode in which the aspect ratio of the original video signal is changed automatically based on information about the original video signal, and an operation mode in which the aspect ratio of the original video signal is changed using a fixed scaling factor determined without referring to the original video signal; background signal generation means for generating a background video signal serving as a background of the processed video signal; and video signal combination means for executing a process of combining the processed video signal and the background video signal, both having been subjected to aspect ratio conversion, to generate a synthesized video signal.
