1. An information processing device, comprising: a sensor that detects a user within a detectable range from the sensor; and processing circuitry that detects a face of the user based on image data captured by the sensor; calculates system control information for optimizing an output of a display system based on a respective position of the user detected by the sensor; analyzes the face of the user to determine an age of the user; calculates a correction coefficient to correct the system control information according to the age of the user; corrects the system control information based on the correction coefficient; and optimizes the output of the display system based on the corrected system control information.
