1. A display data output apparatus comprising:
- a storage unit for storing therein one or more display data pieces;
a priority assignment unit operable to assign priorities to identifiers that respectively identify candidate display data pieces, each of the candidate display data pieces having a possibility of being displayed subsequent to a current display data piece being displayed;
a generation unit operable to generate the candidate display data pieces according to the priorities and store the generated candidate display data pieces in the storage unit, generating and storing one piece at a time;
an input reception unit operable to receive input from a user;
a determination unit operable to determine one of the identifiers based on the received input; and
a display control unit operable to (i) when one of the candidate display data pieces identified by the determined identifier is stored in the storage unit at the time of receiving the input, read the one candidate display data piece from the storage unit and output the read one candidate display data piece, and (ii) when the one candidate display data piece is not stored in the storage unit at the time of receiving the input, generate and output the one candidate display data piece.

Abstract
Provided is a display data output apparatus for outputting a display image to be displayed on a screen. In order to reduce a time until the displayed image is displayed after input is received from a user, the display data output apparatus assigns priorities to a plurality of display objects that each have a possibility of being displayed subsequent to a current display state based on a predetermined assignment method, and sequentially generates a plurality of display data pieces according to the priorities. For example, the display data pieces are generated, starting from the one that requires a long time to be generated.
