Screen transition control device

摘要

A history information storage unit ( 104 ) stores screen history information while a display data storage unit ( 105 ) stores display data for displaying a screen. Moreover, a screen transition control unit ( 103 ) controls the screen transition. Even when screen display data is discarded, a screen transition control device ( 102 ) holds a history of the screen by storing the screen state of the screen, whose display data is discarded, as a discard state in the history information storage unit ( 104 ).
