Abstract
A terminal device for mobile communication and a screen display method are provided for appropriately correcting the amount of scrolling so that a display element should not be displayed across the boundary of a display screen when the screen with a plurality of display elements of different types mixed therein is scrolled. A scroll instruction unit outputs a scroll instruction such as one-line vertical scrolling based on the operation inputted by a user through an input unit. A basic amount determination unit determines a basic moving amount according to the scroll instruction. A display element searching unit calculates a provisional display start position based on the basic moving amount and a display start position held in a display element information holding unit, and searches for a display element that is supposed to be displayed across the boundary of the display screen. An offset determination unit determines one of the display elements as a reference display element based on priority information, and calculates an offset moving amount. A calculation unit calculates an actual moving amount on the display screen by adding the offset moving amount to the basic moving amount.
