Claim:
A display controller comprising: display control means by which a partial display of a Web (World Wide Web) page is performed when the Web page is displayed on display means, while a range of the Web page corresponding to a screen size of the display means is a display range, and the Web page is displayed on display means by changing the display range of the Web page, in response to an operation of operating means; display range detecting means for detecting a display range of the Web page displayed on the display means by the display control means; a key input pattern database in which information indicating an operation intended by a user is stored per key input pattern of the operating means; a home position database per URL for registering a home position used as the first display range when a Web page is displayed, together with URL (Uniform Resource Locator) information of each Web page; key input pattern detecting means for detecting a key input pattern of the operating means when the Web page is displayed by the display control means; and home position registering means for registering a home position when the key input pattern detected by the key input pattern detecting means is a key input pattern indicating a home position on the Web page, wherein a key input pattern includes a continuous operation time of a single key and a coordinate shift of a predetermined point of the Web page in response to the operation of the single key, wherein registering a home position comprises (1) detecting whether the key input pattern indicates a home position on a Web page, and (2) registering a display range of the Web page detected by the display range detecting means as a home position corresponding to the Web page and URL information of the Web page, in the home position database per URL, wherein detection of whether the key input pattern indicates a home position is done by referring to information being stored in the key input pattern database and indicating an operation content intended by the user, based on the key input pattern of the operating means detected by the key input pattern detecting means, wherein the home position registering step determines a user's intention to reach a home position when the key input pattern indicates one operation selected from the group consisting of a continuous operation of the operation means at a predetermined interval, a continuous operation of a page-turning key of the operating means, and a repeated operation between two operation keys of the operating means for a predetermined period of time, and wherein, when the Web page is displayed on the display means, the display control means detects a home position corresponding to URL information of the Web page to be displayed, by referring to the home position database per URL based on the URL, information of the Web page to be displayed, and displays first a display range of the home position on the display means.
