Abstract
A portable information terminal apparatus capable of high-speed display screen scroll processing. An up/down scroll command signal control unit detects the number of unprocessed scroll command signals. A display control unit activates a partial screen update unit if at least two unprocessed scroll command signals are found based on processing executed by the up/down scroll command signal control unit, and activates a total screen update unit if only one unprocessed scroll signal is found remaining. The partial screen updating unit partially updates a display screen based on processing by the display control unit, where as the total screen update unit totally updates the display screen based on processing of the display control unit.

3. A portable information terminal apparatus, comprising:
-
radio communication means;
control means for at least executing data processing;
a display screen capable of executing at least one of upward scrolling and downward scrolling at least by a display line basis; and
an input device for generating at least one of an up-scroll command signal and a down-scroll command signal according to an operation of said input device by a user, wherein a radio wave transmitted from a transmission base station is received by said radio communication means and said control means extracts information from a terminating signal carried by said radio wave and displays at least said information onto said display screen, said portable information terminal apparatus further comprising;
up/down scroll command signal control means capable of detecting a number of unprocessed scroll command signals;
display control means for activating a partial screen update means if at least two unprocessed scroll command signals are found based on processing executed by said up/down scroll command signal control means and for activating a total screen update means if only one unprocessed scroll signal is found remaining;
wherein said partial screer updating means partially updates said display screen based on processing by said display control means, and said total screen update means totally updates said display screen based on processing by said display control means. - View Dependent Claims (4)
