摘要: A plurality of object arrays in which a plurality of objects are sorted under a plurality of order conditions are generated. A display image is generated by sorting the objects in an order for each object array to line up in the first direction for each of the plurality of object arrays, selecting one object of a first object array of the plurality of object arrays as a reference object, and sorting the objects for each of the plurality of object arrays so that the reference object and objects corresponding to the reference object included in the object arrays other than the first object array line up in the second direction.
