Or put into practice this method.Additionally, any aspect described herein can include at least one element of claim.
Each embodiment of the present invention is described below with reference to accompanying drawings.
The present invention proposes a kind of page zoom-in and zoom-out method, and Fig. 1 shows the stream of the page zoom-in and zoom-out method of embodiments of the invention
Cheng Tu, including step：
As shown in figure 1, in step S110, after Web page zoom-in and zoom-out instruction is received, obtaining the display screen of terminal unit
The current zoom ratio of the scale objects on curtain in shown Webpage.Wherein, the current zoom ratio is the contracting
It is rivals in a contest the current size of elephant and the ratio of original size.Uniform zoom is scaled due to described, so the scaling also may be used
With with the current width of the scale objects with the ratio of original width representing.
The present invention an example in, the terminal unit can be the equipment for carrying out web page browsing, including but do not limit
In mobile terminal device, PC equipment, it can also be non-touch screen that the display screen can be touch screen.
In an example of the present invention, scaling instruction can be triggered by various ways.Can be by clicking on Mus
Mark is clicked on the display screen by finger to trigger, or by operating the button on terminal unit triggering.
When the display screen is touch screen, can move on the display screen to trigger by double fingers.
In an example of the present invention, the scale objects can be the web page element of Webpage, such as on webpage
Text block, or the picture on webpage.As shown in Fig. 2A to Fig. 2 B, webpage is typically made up of many different content blocks,
The corresponding content of each Web page content block can regard a web page element as.Web page element can be the body text of webpage, can
Being the ad content on the picture, or webpage on webpage.When generally user is zoomed in and out to webpage, one can be selected
Scale objects, even if being sometimes that whole webpage is zoomed in and out, but the purpose of scaling is all by some webpage units in webpage
Element zooms to suitable size.For example：It is when user wants to see the pictures on webpage, then this picture is right as scaling
As；User think over reading certain then the text of news when, then using this text as scale objects.In an example of the present invention
In, when using finger, movement zooms in and out operation on the display screen, can be by double positions of the finger line central point on screen
The content for putting corresponding page area is defined as scale objects.
Next, in step S120, according to the current zoom ratio and target scale ratio, determining current zoom increment
The factor.
In an example of the present invention, the target scale ratio can be the original width based on the scale objects
It is calculated with preset width.The original width CW refers to the scale objects on the display screen not through scaling
The width shown during process.In another example of the present invention, the preset width is the width W of the display screen, institute
Target scale ratio ES=a*W/CW is stated, a can be the arithmetic number of any setting.In an example of the present invention, a values can be with
Take 1.
In an example of the present invention, the target scale ratio can be set in advance.
In an example of the present invention, the scale objects when scaling increment factor can be each zoom operations
Scaling incrementss.For example：When scaling instruction is, by clicking on the scale objects and when sending, often to click on one
It is secondary, the scaling of the scale objects is increased into a scaling increment factor, such as：It is 100% in the scaling increment factor
When, often click on once, the scaling of the scale objects is increased into 100%.
In an example of the present invention, when the display screen is touch screen, the Web page zoom-in and zoom-out instruction response
In finger moving and when sending on the touchscreen is detected, the scaling increment factor can be finger on the touch screen
Moving Unit apart from when the scale objects scaling incrementss.For example：Finger often moves 1mm, the scale objects
Scaling increase by one scaling increment factor, such as：When the scaling increment factor is 10%, finger is often moved
The scaling of the scale objects is increased by 10% by 1mm.
In an example of the present invention, the scaling increment factor V can be according to current zoom ratio and the mesh
The absolute value of the difference of mark scaling determines.The absolute value │ of the difference of current zoom ratio S and target scale ratio ES
S-ES │ are proportional, and │ S-ES │ are less, and the scaling increment factor V is less, and │ S-ES │ are bigger, the scaling increment factor V
It is bigger.The scaling increment factor V can be the function of │ S-ES │, be represented by formula V=f (│ S-ES │).For example：V= m│S-ES
│, wherein, m values are positive number.
In another example of the present invention, when the display screen is touch screen, the Web page zoom-in and zoom-out instruction rings
Ying Yu detect finger on the touchscreen when moving and sending, the scaling increment factor is can also be according to the current contracting
Put the resistance that the absolute value and finger of the difference of ratio and target scale ratio are detected when moving on the touch screen
It is determined that.
In an example of the present invention, the display screen of the terminal unit is made up of the material of adjustable resistance, described
Mobile device is provided with resistance regulation module, and the resistance regulation module is detecting current zoom ratio and target scale ratio
When the absolute value of difference changes, according to the absolute value of the current zoom ratio and the difference of target scale ratio with it is described
The corresponding relation of resistance adjusts resistance when finger is moved on the screen.The resistance of screen is bigger, and finger is moved on screen
It is dynamic to be just more difficult to.
In an example of the present invention, resistance F can be the difference of the current zoom ratio and target scale ratio
Absolute value │ S-ES │ function, F=f（│S-ES│）, │ S-ES │ are less, and F is bigger, and │ S-ES │ are bigger, and F is less.Resistance F and │ S-
The relation of ES │ can be as shown in Fig. 3 A to 3B.As shown in Figure 3A, F=x/ │ S-ES │, x>0.In a preferred version of the present invention
In, x=1.As shown in Figure 3 B, F=y/ │ S-ES │ ^2, y>0.
In an example of the present invention, increment factor V=f is scaled（│ S-ES │, F）, V-value is jointly true by │ S-ES │ and F
Fixed, when │ S-ES │ get over hour, V is bigger；When F is bigger, V is less.For example：V=m │ S-ES │/F ^n, wherein m>0, n>1.
In an example of the present invention, the current zoom ratio of the scale objects can be by first detecting that finger exists
Displacement on the touch screen, is then based on what detected finger displacement determined.For example, finger is often moved
Used as once scaling, current zoom ratio is equal to be the scaling before time scaling the operating effect that unit distance causes
The ratio of object and the scaling increment factor sum when secondary scaling.
Next, in step S130, being zoomed in and out to the scale objects according to current zoom increment factor.
In an example of the present invention, scaling increment factor will be first calculated during each zoom operations and is contracted again
Put.For example：Correspondence is clicked on screen or button using mouse or finger to send during scaling instruction, and scaling is calculated after clicking on every time
Then increment factor zooms in and out.
In an example of the present invention, for the mobile-initiated zoom operations of finger on touch screen, complete in finger
Once in continual moving process, finger is per Moving Unit distance, it is necessary to which calculating once scales increment factor, then utilizes
The increment factor carries out ensuing scaling, and this unit distance is infinitesimal distance, that is to say, that once moved in finger
In dynamic process, scaling increment factor is constantly to change.
According to the page zoom-in and zoom-out method of the present embodiment, the scale objects scaling closer to target scale ratio
When, scaling increment factor can become zooming in or out speed and becoming very slow for scale objects less, during scaling, be easy to user
The size of scale objects is finely adjusted, allows users to accurately achieve the scaling target sizes wanted.
