(Frame rate setting example 2)
Hereinafter, a second setting example of the common frame rate, which is a setting example of the common frame rate when a plurality of fixed frame rate video signals are input to the video processing device 10, will be described. The process for setting the common frame rate, which will be described in this example and the subsequent frame rate setting examples, corresponds to the process in step S102 described above. The acquisition unit 12 according to this example acquires a third video signal having a fixed frame rate in addition to the first video signal and the second video signal.
