Abstract

The present invention is to provide a method of enlarging display content of an electronic apparatus having an enlarge display mode, which comprises the steps of determining whether or not the enlarge display mode is being activated; reading at least one enlarge parameter preset in the enlarge display mode when the enlarge display mode is activated; enlarging the content outputted by a man-machine interface according to the enlarge parameter; canceling an external frame of a decorative screen of the man-machine interface for ornamenting images, and displaying the enlarged content in accordance with the enlarge parameter on a display of the portable electronic apparatus In such a way, the user is able to view the enlarged content of the man-machine interface being outputted without changing resolution of the display.

Claims

1. A method of enlarging display content of a portable electronic apparatus having an enlarge display mode, which comprises the following steps for the portable electronic apparatus to output a man-machine interface:

determining whether or not the enlarge display mode is being activated;

when the enlarge display mode is being activated, reading at least one enlarge parameter preset in the enlarge display mode, and enlarging a content outputted by the man-machine interface according to the enlarge parameter, and

canceling an external frame of a decorative screen of the man-machine interface for ornamenting images, and displaying an enlarged content in accordance with the enlarge parameter on a display of the portable electronic apparatus.

2. The method as set forth in claim 1, wherein the portable electronic apparatus is adapted to switch from enabling the enlarge display mode to disabling the enlarge display mode according to a switching signal, or from disabling the enlarge display mode to enabling the enlarge display mode according to the switching signal.

3. The method as set forth in claim 1, wherein when the portable electronic apparatus enters the man-machine interface of the enlarge display mode, at least an enabling/disabling option is presented on the display of the portable electronic apparatus, and a switching signal can be generated by selecting or cancelling the enabling/disabling option which allows the portable electronic apparatus to switch from enabling the enlarge display mode to disabling the enlarge display mode or switch from disabling the enlarge display mode to enabling the enlarge display mode.

4. The method as set forth in claim 1, wherein the enlarge parameter comprises font size, font codes and picture enlarging ratio.

5. The method as set forth in claim 1, wherein the enlarged content is displayed on the display by the portable electronic apparatus according to the following steps:

receiving the enlarged content, and calculating a total pixel in width of the enlarged content;

determining whether or not the total pixel in width of the enlarged content exceeds the maximum width of the display range of the display;

if yes, displaying the enlarged content that exceeds the maximum width of the display range of the display on a next row, and repeating this step till the enlarged content of each row does not exceed the maximum width of the display range of the display; and

outputting the enlarged content in the order as divided in rows to the display.

6. The method as set forth in claim 5, wherein if the total pixel in width of the enlarged content is determined as not exceeding the maximum width of the display range of the display, then directly displaying the content of the man-machine interface on the display of the portable electronic apparatus.
