Patent ID: 8164690

Claim:
An image display device comprising: an image generating unit configured to generate image signals based on received digital signals; an image segmenting unit configured to extract the image signals included in a segment area being an arbitrary area portion from the image signals outputted from the image generating unit; a display area setting unit configured to set a display area being an arbitrary area portion displaying the extracted image signals; an image expanding unit configured to allocate the extracted image signals to the display area and generate an expanded image; an image synthesizing unit configured to synthesize the image signals outputted from the image expanding unit and image signals outputted from the image generating unit; and a signal determining unit configured to determine information on a program during reception from the digital signals, wherein if it is determined by the signal determining unit that the program changes from one to a commercial message: if setting is provided so that only the image signal outputted from the image generating unit is selectively outputted, the output from the image synthesizing unit is changed so that only the image signal outputted from the image generating unit is selectively outputted; and if setting is not provided so that only the image signal outputted from the image generating unit is selectively outputted, image signals synthesized by image signals outputted from the image generating unit and the image signal outputted from the image expanding unit are outputted from the image synthesizing unit.
