Information processing system and information processing method

An information processing method in an information processing system, the method comprising:

• a signal processing step of, on a basis of an imaging equipment synchronization signal, performing processing on an input video signal that is a video signal of a first frame rate different from a frequency of the imaging equipment synchronization signal;
• an output step of outputting a video signal of a frame rate different from the frequency of the imaging equipment synchronization signal on a basis of the processing on the input video signal,
• wherein the imaging equipment synchronization signal is used to synchronize the information processing system to a camera that is external to the information processing system and that images a video displayed according to the video signal of the frame rate different from the frequency of the imaging equipment synchronization signal, and
• wherein the signal processing step comprises generating, for the input video signal on a basis of the imaging equipment synchronization signal, an output video signal that is the video signal of a second frame rate set on a basis of the first frame rate and is synchronized with the imaging equipment synchronization signal;
• and
• a moving step of moving, in the output video signal, a vertical blanking period of each frame included in one cycle of the imaging equipment synchronization signal after a last frame included in one cycle of the imaging equipment synchronization signal.
