Drive control device, drive control method, information processing system, and information processing method for information processing system

An information processing system comprising:

• a display including display units, each of the display units including light emitting diodes (LEDs) arranged in an array and a drive control device configured to control driving of the LEDs;
• and
• a distributor configured to receive input of a video signal, perform predetermined signal processing on the video signal, and distribute the video signal among the display units, wherein
• the drive control device includes
• a light emission control unit configured to control light emission of the LEDs, and
• the light emission control unit performs control to make a length of a period during which the LEDs are off shorter than a time indicated by an input signal.

An information processing method for an information processing system, the information processing system including:

• a display including display units, each of the display units including light emitting diodes (LEDs) arranged in an array and a drive control device configured to control driving of the LEDs;
• and
• a distributor configured to receive input of a video signal, perform predetermined signal processing on the video signal, and distribute the video signal among the display units,
• the information processing method comprising a light emission control step of controlling light emission of the LEDs by the drive control device, wherein
• in a process of the light emission control step, a length of a period during which the LEDs are off is controlled to be shorter than a time indicated by an input signal.
