On the other hand, when characters and figures are displayed in a large size for easy viewing, only a part of the whole can be displayed on the LCD at a time, and when it is desired to see another part of the whole, it is necessary to scroll or switch the display page. However, the larger the characters and graphics are displayed, the higher the frequency of scrolling and page switching becomes, making it difficult to use.

[0005] Therefore, it is necessary to first display characters or figures in a small size even if it is difficult to view the entire image, and to magnify and display a particularly desired portion.

However, in general, several steps of operation are required for enlarging and displaying a target display portion of a GUI, and a magnification can be selected from a plurality of options on a menu, a numerical value input, a scroll, or the like. In many cases, only the setting with the bar can be performed, and several trials and errors are required to obtain the display of the expected magnification, and it is difficult to judge how much the image should be enlarged to obtain an appropriate screen.

As described above, in the conventional portable information terminal device, it is difficult to easily enlarge and display a target area of the GUI displayed on the LCD.

[0008] The present invention has been made to solve the above-mentioned problems, and has an LC
An object of the present invention is to provide an information display method and a portable information terminal device in which an operation of displaying a target area of the GUI displayed at D at a target magnification is simple.

[0009]

In order to achieve the above object, the present invention provides a portable terminal device having a touch panel on an LCD.
By displaying I and measuring the area to be enlarged and viewed from the touch panel, the area is enlarged and displayed on the entire LCD screen. Then, when the resolution is reduced to reduce the display area, the enlargement method is to reduce the thinning rate and enlarge it, or conversely add extra dots to the dot image to be displayed and enlarge it I do. When the dot pitch is reduced in order to reduce the display area, an extra dot is added to the dot image to be displayed and enlarged display is performed.

According to the present invention, the G displayed on the LCD is
An operation of displaying a target area of the UI at a target magnification can be simplified, and an information display method and a portable information terminal device with a simple operation can be provided.
