Display apparatus, display method, and computer program

A display apparatus comprising:

• a generation unit that generates an image provided with a movement object as an object that moves and a trail object indicating a trajectory of the movement of the movement object, the image including a display target area displayed on a cylindrical screen, a first margin area provided outside of one end of the display target area, and a second margin area provided outside of an end on an opposite side of the one end of the display target area;
• and
• a display control unit that causes the cylindrical screen to sequentially display content of the display target area of a plurality of images generated by the generation unit, wherein
• a width of the movement object is equal to or smaller than a width of the trail object,
• when a first movement object that moves in the display target area comes into contact with a boundary of the display target area and the first margin area, the generation unit is configured to arrange, in the second margin area, a second movement object in a same mode as a mode of the first movement object such that the second movement object comes into contact with a boundary of the display target area and the second margin area, and delete the first movement object,
• after deleting the first movement object, the generation unit gradually shortens the trail object added to the first movement object up to that time and generates a plurality of images such that the second movement object enters the display target area from the second margin area, and
• when the entire second movement object enters the display target area from the second margin area, the generation unit starts to generate a trail object to be added to the second movement object.

A display method executed by a display apparatus, the display apparatus executing:

• generating an image provided with a movement object as an object that moves, the image including a display target area displayed on a cylindrical screen, a first margin area provided outside of one end of the display target area, and a second margin area provided outside of an end on an opposite side of the one end of the display target area;
• and
• causing the cylindrical screen to sequentially display content of the display target area of a plurality of images generated in the generating, wherein,
• in the generating, when a first movement object that moves in the display target area comes into contact with a boundary of the display target area and the first margin area, the display apparatus arranges, in the second margin area, a second movement object in a same mode as a mode of the first movement object such that the second movement object comes into contact with a boundary of the display target area and the second margin area, and
• in the generating, the display apparatus generates the plurality of images such that as the first movement object moves out to the first margin area from the display target area, the second movement object enters the display target area from the second margin area.

• and
• sequentially displaying, on the cylindrical screen, content of the display target area of a plurality of images generated in the generating, wherein
• a width of the movement object is equal to or smaller than a width of the trail object,
• in the generating, when a first movement object that moves in the display target area comes into contact with a boundary of the display target area and the first margin area, the display apparatus is configured to arrange, in the second margin area, a second movement object in a same mode as a mode of the first movement object such that the second movement object comes into contact with a boundary of the display target area and the second margin area, and delete the first movement object,
• in the generating, after deleting the first movement object, the display apparatus gradually shortens the trail object added to the first movement object up to that time and generates a plurality of images such that the second movement object enters the display target area from the second margin area, and
• in the generating, when the entire second movement object enters the display target area from the second margin area, the display apparatus starts to generate a trail object to be added to the second movement object.

A non-transitory, computer readable storage medium containing a computer program, which when executed by a computer, causes the computer to perform a display method executed by a display apparatus by carrying out actions, comprising:

• generating an image provided with a movement object as an object that moves, the image including a display target area displayed on a cylindrical screen, a first margin area provided outside of one end of the display target area, and a second margin area provided outside of an end on an opposite side of the one end of the display target area;
• and
• outputting, to a display apparatus including the cylindrical screen, content of at least the display target area of a plurality of images generated in the generating, wherein,
• in the generating, when a first movement object that moves in the display target area comes into contact with a boundary of the display target area and the first margin area, the computer arranges, in the second margin area, a second movement object in a same mode as a mode of the first movement object such that the second movement object comes into contact with a boundary of the display target area and the second margin area, and
• in the generating, the computer generates the plurality of images such that as the first movement object moves out to the first margin area from the display target area, the second movement object enters the display target area from the second margin area.
