Description

Zooming method of display screen of electronic device

technical field

The invention relates to a zooming method of a display screen of an electronic device, in particular to a zooming method of a designated area in a display unit of a portable electronic device.

Background technique

In order to be convenient to carry, many electronic products gradually have a trend of being thin, light and small. For example, notebook computer, tablet computer (Tablet), UMPC (Ultra Mobile PC) or PDA mobile phone, etc. In addition to providing programs or functions commonly used in desktop computers, these products also have an independent display unit. The user can operate or observe the running status of the program in the electronic product through the display unit. However, in order to meet the characteristics of portability, the display unit will use a smaller-sized LCD screen. As a result, some users may have difficulty in reading, so how to improve the readability of the display unit is a new subject.

As far as a notebook computer is concerned, if a higher resolution is used on a small-sized display unit, it will make it difficult for the user to view the information in the display unit. So it was proposed to add zooming in/out to the application. Through the zoom function provided by the application program, the user can enlarge/reduce the information to be read to meet the user's reading habits. Take the Firefox browser (Firefox) as an example, if the user wants to zoom in on the webpage content, the user only needs to press "ctrl" and then scroll the mouse wheel to zoom in/out the webpage content.

However, different zoom function hotkeys are set for different application programs, but the zoom function hotkeys defined by each application program are not the same, and these zoom function hotkeys are mostly combination keys formed by multiple buttons. Therefore, it is impossible for the user to remember all the key combinations. Although the application program provides a zoom function, it does not meet the user's requirements for simple use.

Contents of the invention

In view of the above problems, the main purpose of the present invention is to provide a zooming method of the display screen of the electronic device, which is used to zoom in on a specific area designated by the portable electronic device.

In order to achieve the above object, the zooming method of the display screen of the electronic device disclosed in the present invention includes the following steps: setting the combination of quick keys, loading the trigger event of the quick key into the window operating system as a monitoring event; detecting the triggering of the input device Event; if the window operating system detects the trigger event of the shortcut key, the window operating system executes the window operating system scaling program to zoom the display screen.

The present invention detects a quick key signal sent by the keyboard, and triggers a mouse button scaling event to zoom in on the area where the mouse cursor is located. In this way, the same shortcut key can be used to realize the zooming of the screen of each application program.

Firstly, a combination of quick keys is set, and the trigger event of the quick keys is loaded into the window operating system as a monitoring event (step S110). The triggering mode of the shortcut key is an external interrupt. In other words, it can be regarded as that the program waits for the trigger event of the shortcut key to be triggered after it resides in the window operating system. Detecting the trigger event of the input device, the quick key (step S120 ), wherein the quick key can be a compound key or a single key. If the window operating system detects the trigger event of the quick key, the window operating system executes the window zoom program to zoom the display screen (step S130), and the personal computer operates the window according to the interrupt signal (interrupter) sent by the input device. The system triggers events such as window display and window drawing.

Next, it is detected whether the keyboard sends an end signal (step S140 ), if an end signal is detected, the amplification process is ended, and step S130 is repeated. If no end signal is detected, repeat step S140.

In the present invention, because the fast key signal sent by the keyboard is a hardware interrupt signal, if the application program in execution has the same fast key, the operating system will consider the hardware interrupt signal sent by the keyboard as a priority process, And it will block the shortcut key signal sent by the application. In this way, it can be avoided that when the shortcut key is pressed, the corresponding function of the same shortcut key in the application program will be activated.

In this embodiment, the quick key is a combination of keys in the keyboard. For the convenience of explaining this embodiment, the quick key is defined here as "Ctrl"+"Page up". Of course, it can also be other key combinations. .

For a preferred embodiment of the present invention, please refer to FIG. 2A and FIG. 2B , which are respectively schematic diagrams of browser content before and after zooming.
