To provide a reception device, an image display device, and a reception method capable of shortening the acquisition time of additional information.
A reception device for receiving a video signal includes: a signal system discrimination circuit 41, an aspect acquisition circuit 42, a signal system establishment circuit 62, and an aspect establishment circuit 63. The signal system discrimination circuit 41 discriminates a system of the video signal. The aspect acquisition circuit 42 acquires additional information, which is added to the video signal, based on a discrimination result whenever the signal system discrimination circuit 41 discriminates the system of the video signal. The signal system establishment circuit 62 establishes the system of the video signal when the system of the video signal discriminated by the signal system discrimination circuit 41 is continuously the same first times. The aspect establishment circuit 63 establishes aspect information, based on aspect information acquired by the aspect acquisition circuit 42.
