Embodiment Construction

[0021] Description of preferred embodiments

[0022] A preferred example of the present invention will be described in detail with reference to the accompanying drawings. attached figure 1 It is a block diagram showing the structure of the cellular phone 101 with built-in automatic scrolling function in a preferred embodiment of the present invention. The key event processing part 108 detects the pressing operation of the key 109 and transmits the detection result to the processor 104 . The processor 104 completes subsequent processing work according to the program 102 .

[0023] Once the user presses the key 109 , the key event processing component 108 will send detection information to the processor 104 . When the key is "up key" or "down key", the processor 104 gives an instruction through the image display circuit 106, so that the display position of the content is scrolled up or down. That is, the initial position of the display is changed, whereby the display content...

Abstract

A scroll control device for controlling the scroll of a display screen has a scroll key for requesting scrolling and control means for performing control in such a manner that, when the scroll key has been depressed continuously for a predetermined period of time, an automatic scroll mode is made active and, when the scroll key has been further continuously depressed, the automatic scroll speed is further increased.

Description

field of invention [0001] The present invention relates to a scroll control device, a method for the scroll control device, a communication terminal and a program using the scroll control device. More particularly, the present invention also relates to a method of controlling scrolling for controlling scrolling of a display screen in a communication terminal such as a portable phone (cellular phone). Background of the invention [0002] Portable telephones and portable communication terminal devices such as PHS (Personal Handyphone System) and PDA (Personal Digital Assistant) generally have functions of browsing web pages and e-mails on the Internet. The size of the display screens of these portable communication terminal devices is practically limited. Therefore, when a user uses a terminal to browse content such as webpages and e-mails, it is indispensable to implement a scrolling operation on the display screen, and the operation frequency is very high. [0003] Usually...
