Data processing apparatus, content displaying method, and non-transitory computer-readable recording medium encoded with content displaying program

A content displaying method performed by a data processing apparatus, the data processing apparatus including

• a display portion capable of displaying an image and
• a position detecting portion capable of detecting one or more positions designated by a user on a display surface of said display portion,
• the method causing said data processing apparatus to perform;
• a content displaying step of displaying, on said display portion, a display area corresponding to at least a part of content;
• and
• a gesture event determining step of determining at least one of a plurality of gesture events on the basis of said one or more positions detected by said position detecting portion;
• said content displaying step including
• a display image generating step of generating a display image for displaying said display area on the basis of the at least one gesture event determined in said gesture event determining step, and
• a display control step of displaying said generated display image on said display portion,
• said display image generating step including
• a state storing step of temporarily storing state information for specifying said display area at a time point of start of a gesture period during which one or more positions are continuously detected by said position detecting portion, and
• a prioritized displaying step of, in the case where a first gesture event corresponding to a process involving a change of said display area and a second gesture event corresponding to a process involving no change of said display area are determined during said gesture period in said gesture event determining step, generating a display image for displaying the display area specified by said stored state information, on the basis of said second gesture event.

A non-transitory computer-readable recording medium encoded with a content displaying program performed by a computer which controls a data processing apparatus,

• said data processing apparatus including
• a display portion capable of displaying an image and
• a position detecting portion capable of detecting one or more positions designated by a user on a display surface of said display portion,
• the program causing said computer to perform:
• a content displaying step of displaying, on said display portion, a display area corresponding to at least a part of content;
• and
• a gesture event determining step of determining at least one of a plurality of gesture events on the basis of said one or more positions detected by said position detecting portion;
• said content displaying step including
• a display image generating step of generating a display image for displaying said display area on the basis of the at least one gesture event determined in said gesture event determining step, and
• a display control step of displaying said generated display image on said display portion,
• said display image generating step including
• a state storing step of temporarily storing state information for specifying said display area at a time point of start of a gesture period during which one or more positions are continuously detected by said position detecting portion, and
• a prioritized displaying step of, in the case where a first gesture event corresponding to a process involving a change of said display area and a second gesture event corresponding to a process involving no change of said display area are determined during said gesture period in said gesture event determining step, generating a display image for displaying the display area specified by said stored state information, on the basis of said second gesture event.
