【0003】

On the other hand, the contents on the WEB are generally assumed to be viewed using a browser on a personal computer (desktop type). In other words, the content on the WEB is structured in a form optimized for the screen size of the personal computer, and no special consideration is given to the content display and screen operation on the screen of a small terminal. The current situation. Therefore, improvements are required for WEB access means specialized for small information terminals.

【0004】

Currently, there are various contents scattered on the WEB, and their purposes of use are also various. In addition, due to the price reduction of terminals, the usage style of accessing information outdoors while communicating with a mobile terminal is becoming widespread from the conventional Internet access from a desktop personal computer.

【0005】

Therefore, the problem is that there is a limit to the screen size of small information terminals that pursue portability, and for content that is originally intended to be viewed with a browser on a computer screen, one's purpose within the page is The current situation is that the browsing environment is extremely inefficient while performing operations such as changing settings such as scroll bars and scale settings, relying on the content that can be seen on a small display until the content is reached. The screen operation of the small screen was one of the problems that reduced the work efficiency at the time of WEB access.

【0006】

Here, a conventional method of browsing content on the WEB while changing the scroll bar or changing the scale value in a small information terminal will be described.

【0038】

When browsing in the currently loaded page, operate the screen again with the joystick (S10).

【0039】

Next, the operation assigned to the joystick operation will be described with reference to FIG.

【0040】

Like the small information device 14 shown in the upper part of FIG. 3, the joystick 15 is installed at a position where it can be operated with a finger when it is held with one hand. Therefore, it is possible to scroll, enlarge, and reduce the screen while carrying it with one hand.

【0041】

The screen operations assigned to the joystick operation are shown in the lower part of Fig. 3.

【0042】

When the joystick 15 is moved up, down, left and right, the screen scrolls by the specified displacement. Also, by pushing the joystick 15 in the depth direction, the content currently displayed on the display can be enlarged or reduced.

【0043】

Press the joystick 15 once for a short time to enlarge it, and press it for a long time to reduce it.

【0044】

The screen scrolling and screen scale changing operations in each operation of the joystick 15 are specifically shown with reference to FIGS. 4, 5, 6, 7, 8, and 9.

【0045】

【0050】

Next, FIG. 10 is an explanatory diagram of the mechanism of the image data loading function according to the present invention for performing high-speed display switching.

【0051】

HTML files existing on the WEB are usually structured assuming browser browsing on a personal computer, and when browsing content on a small information terminal, only a part of the page can be displayed. Therefore, the content is obliged to be browsed while frequently repeating the screen operation.

【0052】

However, when switching screens, if image data is included in the display area, the image data included in the display area is simply read into the memory, and the image is expanded and displayed by the CPU. Since a series of processes are repeated every time, there is a problem that the display is delayed due to high-speed screen operation.

【0053】

In the method shown in FIG. 10, first, the image data in the area adjacent to the area of the content currently displayed on the small information terminal is detected, and while the user is browsing the screen, that is, the CPU. This is a mechanism for loading image data into the memory in advance while processing is not required. In FIG. 10, when the image D is mainly displayed, the images that may be displayed in the next screen operation are the image C, the image E, and the image G. Therefore, when the user is browsing the image D, the image C, the image E, and the image G are started to be loaded into the memory. Next, when the user operates the screen, the image assigned to the display area is already expanded in the memory, and can be displayed on the screen at high speed. By recursively loading the display candidate image in the memory during the browsing of the user, it is possible to switch the screen display at high speed for the image operation by the continuous joystick operation.

【0054】

[Effect of the invention]

As is clear from the above description, the screen operation device according to the present invention displays data such as a central processing device that processes requested information, a display device that displays windows, graphic elements, characters, and the like, characters, numerical values, and positions. In a processing device consisting of an input device such as a keyboard, a tablet, a mouse, an operating system, a main storage device for storing a running program such as a window system, and a secondary storage device for storing a program, text data, etc. When browsing content on the WEB on a small display, you can scroll the screen vertically and horizontally, and enlarge and reduce the screen with just the three-dimensional operation of the joystick equipped on the terminal. In a small information terminal, an advantageous effect of providing an environment in which content can be easily browsed by only one-handed joystick operation can be obtained.

【0055】

Further, in order to realize high-speed screen display switching in synchronization with the user's continuous joystick operation in a small information terminal, the above-mentioned function acquires image data that may be displayed when the next screen is changed in advance and stores the memory. By automatically loading the data on the screen, the screen can be displayed smoothly for continuous joystick operations, which has the advantageous effect of providing a comfortable content browsing environment with more intuitive operations.
