Information processing device, display system, and display method

A display system comprising:

• a detection unit configured to detect a parking position of a vehicle parked in a parking lot;
• a first imaging unit configured to image a user alighting from the parked vehicle;
• a storage unit configured to store the detected position and the user;
• a second imaging unit configured to image a user passing along a path along which the user is able to move to the parking lot;
• an extraction unit configured to extract a user imaged by the second imaging unit out of users imaged by the first imaging unit with reference to the storage unit;
• a calculation unit configured to calculate a time over which the extracted user moves from a position at which the user has been imaged by the second imaging unit to the parking position at which the vehicle from which the user has alighted has been parked;
• and
• a display unit configured to display a relationship between the time based on the calculation result and the position of the parking lot.

A display method comprising:

• acquiring a parking position of a vehicle parked in a parking lot;
• acquiring a first captured image in which a user alighting from the parked vehicle is imaged;
• storing the detected position and the user in a storage unit;
• acquiring a second captured image in which a user passing along a path along which the user is able to move to the parking lot is imaged;
• extracting a user captured in the second captured image out of users captured in the first captured image with reference to the storage unit;
• calculating a time over which the extracted user moves from a position at which the user has been imaged in the second captured image to the parking position at which the vehicle from which the user has alighted has been parked;
• and
• displaying a relationship between the time based on the calculation result and the position of the parking lot.
