Patent number: 7966044Abstract: A medium storing a program for display control. When the program is executed by a computer realized in a mobile terminal, the mobile terminal operates as follows. An area-information storing unit stores information on a first display area of an external display device and a second display area of a built-in display. A screen-data production unit acquires content to be displayed, and produces screen data corresponding to the first display area. An entire-image display unit divides the screen data into partial areas each corresponding to the second display area, adds to the entire screen data area-display data indicating the extent of each partial area and a corresponding identifier, and displays the screen data on the external display device. On receipt of an identifier, a partial-image display unit extracts a portion of the screen data for a partial area corresponding to the identifier, and displays the portion on the built-in display.Type: GrantFiled: February 19, 2008Date of Patent: June 21, 2011Assignees: Fujitsu Limited, Fujitsu Frontech LimitedInventors: Fumiyuki Hashimoto, Yoshiyuki Okada, Yoshiaki Kageyama, Shinobu Tamura, Rumiko Matsuda, Koji Sato, Shigenori Sasaki
