Display device, display method, and recording medium

A display device comprising:

• a memory;
• and
• a processor coupled to the memory, wherein the processor executes a process comprising:
• acquiring user information including a parallax amount from an external device of each user;
• calculating position information of each user by using the external device of each user;
• adjusting data, included in image information, of a stereo image including a pair of a first image and a second image according to a parallax amount of each user included in each piece of the user information;
• and
• outputting image information adjusted by the adjusting on the basis of area information indicating a relationship between an area of a display screen of a naked-eye monitor and an area where an image of the area of the display screen is able to be viewed and the position information of each user.

A display method performed by a computer, the display method comprising:

• acquiring user information including a parallax amount;
• counting the number of users from each piece of the user information and generating a display schedule indicating timing of opening/closing of a first shutter and a second shutter of each pair of glasses with shutters of each user on the basis of the number of users;
• adjusting, using a processor, data of a plurality of stereo images, included in image information, each of which includes a pair of a first image and a second image according to a parallax amount of each user included in each piece of the user information;
• controlling opening/closing of each of the first shutter and the second shutter of the each pair of glasses with shutters on the basis of the display schedule;
• and
• outputting adjusted image information.
