Information processing system and information processing method

An information processing system comprising

• circuitry configured to, on a basis of a relation between a vertical blanking period of a video displayed on a display section and an exposure time of an imaging unit that images the display section, control the vertical blanking period of the video displayed on the display section,
• wherein the circuitry is further configured to control the vertical blanking period so that the exposure time is an integral multiple of a light emission cycle of the display section, and
• wherein in a case where the vertical blanking period is not included in an exposure period of the imaging unit, the circuitry is further configured to control the vertical blanking period so that the exposure time is an integral multiple of a light emission cycle of the display section.
