Embodiment

The solution of the embodiment of the invention mainly is: the screen content enlarging function that the terminal is set; The user chooses the content that needs amplification from original screen through view-finder; Imaging screen carries out enlarged and displayed to the content in the view-finder; The user can drag view-finder and imaging screen moves arbitrarily on screen, and can change the size of view-finder and imaging screen through single-point or multi-point touch arbitrarily; Can also in imaging screen, operate simultaneously, like the webpage clicking link, click interested icon, access application program and literal is selected and copy etc., make things convenient for the user to watch and read, to promote user's experience effect to being exaggerated content.

Terminal of the present invention can be for having any electronic curtain display device of touch screen functionality.

With the touch-control mobile phone is example, and traditional touch-control cellphone subscriber in order to find to browse point of interest, need carry out frequent convergent-divergent and move operation to webpage when carrying out web page browsing.When amplifying with move operation; Target web can recomputate sets type adaptive whole screen; Make that the refresh time of whole screen is longer, the content of webpage is many more more complicated, and screen-refresh speed is just slow more; Frequent full frame refreshing can produce a large amount of period of reservation of numbers, seriously consumes user's the effective reading time.Under traditional approach; User's zoom operations and move operation produce contradiction; The user need amplify webpage in order to see webpage clearly, but after the webpage amplification, the user then need move webpage when finding next point of interest for other parts of watching webpage; If enlargement factor is big more, then user's frequency that need move is just big more; Watch the speed of point of interest in order to accelerate to find the next one; The user need dwindle the position that webpage helps confirm fast next point of interest again; But,, then can cause the user not see Chu's web page contents if the ratio of dwindling is improper; Cause the user can't find next point of interest efficiently, user's webpage of having to amplify once more.

Therefore, frequent webpage is carried out convergent-divergent and moves the effective browsing time that has taken the user, and seriously reduced the efficient that the user finds to browse point of interest.When webpage was more complicated more greatly, user experience was poor more.

In addition; Though Windows operating system with Loupe tool can carry out the part to screen content and amplify; But its enlargement factor is fixing several ranks that preset; Can not step-less adjustment, and the adjustment of the size of the capture area of its magnifier (being equivalent to the view-finder among the present invention) is to realize indirectly through adjustment magnifier frame (being equivalent to imaging screen of the present invention).The zone of capture area is that Windows retrodicts out according to the size of imaging screen and the enlargement factor of Set For Current automatically; And view-finder is invisible for the user; Therefore; The user can't direct feel to the size of view-finder, shape with and with the relative position relation of whole screen, make the user in the targeted variation of moving magnifier during to interested screen content position.

Simultaneously; Because the imaging screen rear can't be shown by the profile of the original screen content that imaging screen blocked; Cause view-finder and imaging screen to be lost, isolated the associative perception of watching of the original full screen content of screen with respect to the relative position relation of screen original contents overall region.Because the associative perception of the original full screen content of screen is isolated; In the content area of user after seeing amplification; Can't see corresponding capture area zone simultaneously and be exaggerated the profile of the screen original contents that mirror covers and the relativeness between whole this three of screen, cause the user to be difficult to fast magnifier directly moved to and want the screen content module region observed.Particularly for many frames pages of complicacy; The user need regulate the size of enlargement factor and imaging screen repeatedly; Just can make being presented on the imaging screen of content intact in the webpage subframe after the amplification of wanting to watch, cause user's user experience when watching this type of webpage seriously to descend.

Based on this; The present invention improves prior art; Can be under the prerequisite that does not change the webpage Global Information, make the arbitrarily subregion of web page contents on the enlarged and displayed screen of user, make things convenient for the user to watch webpage; Accelerate the speed that the user finds point of interest in the webpage, promote the viewing experience that the user uses portable terminal greatly.

Particularly, as shown in Figure 1, one embodiment of the invention proposes a kind of screen content amplification display method, comprising:

Step S101, the terminal is chosen from original screen through view-finder and is treated the enlarged and displayed zone;

In order to realize that selection area content in the screen is carried out enlarged and displayed, the present embodiment terminal is provided with Zoom lens system, and this Zoom lens system comprises view-finder and imaging screen, and view-finder and imaging screen are provided with screen on terminal screen.Wherein, View-finder is finding a view of Zoom lens system and position reference; Be used for user's interest zone in the cover screen original contents; Be that the zone that view-finder limits is the selecteed zone of terminal screen original contents, the user can oneself need choose the zone of treating enlarged and displayed through view-finder from the original contents of terminal screen; Imaging screen is used for treating in the original contents of the selected terminal screen of enlarged and displayed view-finder the content in the zone of enlarged and displayed.

The relative position of the size of imaging screen and imaging screen and view-finder calculates adjusting by Zoom lens system according to predefined enlargement factor automatically; Be used for guaranteeing that content in the view-finder can be complete after being exaggerated under the current enlargement factor is presented on the imaging screen; And guarantee the integrality of watching of imaging screen, guarantee that promptly the zone of imaging screen always is positioned at the inside, border of terminal screen.

Magnifier calculates a suitable initial enlarged and displayed multiple by Zoom lens system according to existing screen content display resolution automatically when initial start, the screen that contrast resolution is high more then can be provided with higher initial enlarged and displayed multiple.

View-finder size during the magnifier initial start is the size of Zoom lens system acquiescence appointment, and the position of view-finder is a Zoom lens system acquiescence appointed positions.

The size of imaging screen and position be according to size and the position and the predetermined enlargement factor setting of view-finder, such as, can the centre coordinate position of imaging screen in screen be set according to centre coordinate position and the predetermined enlargement factor of view-finder in screen.

As shown in Figure 2, Fig. 2 is view-finder and an imaging screen acquiescence relative position relation synoptic diagram in the present embodiment.Terminal screen is provided with Loupe tool and enables control knob, through this button, and can the opening and closing magnifying function.

After opening Loupe tool, the default location of the relative view-finder of imaging screen is to be benchmark with the view-finder center, the display position that calculates imaging screen by the level and the enlargement factor of Set For Current.Such as the upper left corner with screen is the initial point of coordinate system, the coordinate position of current view-finder be (X1, Y1), enlargement factor is Z, then the acquiescence center position coordinates of imaging screen be (X1*Z, Y1*Z).

In addition, the imaging screen of magnifier and the relativeness between the view-finder can also be set by user flexibility.The interlock control knob (as shown in Figure 2) that the user can be provided with on terminal screen through Zoom lens system; Setting the interlock of imaging screen and view-finder promptly moves simultaneously; When just the user moves view-finder; Imaging screen and view-finder move simultaneously, and when perhaps user's mobile imaging shielded, view-finder and imaging screen moved simultaneously; Or it is motionless to set imaging screen, rests on the fixed position on the screen of user's appointment, moves view-finder separately.Simultaneously the magnifier moving handle can also be set on screen.

As shown in Figure 3, Fig. 3 is that magnifier moves synoptic diagram in the present embodiment.Grid regions among Fig. 3 (except that the frame of view-finder and magnifier) all is the focal area that magnifier moves, should the zone and do not discharge when user's touch-control, and magnifier gets into removable state, and this moment, the user can drag magnifier position arbitrarily to the screen.

As shown in Figure 4, Fig. 4 is the synoptic diagram of imaging screen stationkeeping in the present embodiment.When the user pressed the interlock control knob, it is not removable that the position of imaging screen will be fixed on current location, and view-finder still can move arbitrarily.

When view-finder and imaging screen move when promptly linking simultaneously, view-finder can be positioned at imaging screen, perhaps is positioned at outside the imaging screen; Perhaps the frame with imaging screen intersects.

When the user set imaging screen and view-finder and moves simultaneously, Zoom lens system calculated the correct position of imaging screen on screen in real time, guarantees complete being presented on the terminal screen of imaging screen.When moving view-finder near screen border as the user, also can exceed screen border by the imaging screen of default location relation, system will guarantee that the zone of imaging screen drops in the visual screen scope of user through calculating this moment.

Like Fig. 5, shown in Figure 6, Fig. 5 and Fig. 6 are that imaging screen position self-adaptation showed synoptic diagram when view-finder was near screen edge or corner in the present embodiment.When view-finder during near screen edge or corner; Imaging screen is if show by the acquiescence relative position relation with view-finder; The subregion of imaging screen may exceed screen border; Zoom lens system will calculate imaging screen suitable display position on terminal screen this moment, guarantee that complete imaging screen zone drops in the visual screen scope of user.Such as the upper left corner with screen is the initial point (0,0) of coordinate system, and the lower right corner of screen is that (X0, Y0), the width of current view-finder is W, highly is H for the border of coordinate system.The coordinate position at current view-finder center be (X1, Y1), enlargement factor is Z; Then the acquiescence center position coordinates of imaging screen is (X1+W/2*Z; Y1+H/2*Z), if X1+W/2*Z＞X0 or＜0, the expression imaging screen exceeds the indication range of current screen in the horizontal direction; Then magnifier will move to new X coordinate position in X (level) direction, and make X1+W/2*Z＜X0 or＞0; If Y1+H/2*Z＞Y0 or＜0, the expression imaging screen exceeds the indication range of current screen at vertical direction, then magnifier will move to new Y coordinate position in Y (vertically) direction, and make Y1+H/2*Z＜Y0 or＞0.

Step S102, the original display content in the enlarged and displayed zone of treating that view-finder is chosen is presented in the imaging screen with predetermined magnification ratio, and imaging screen and view-finder are arranged in the original screen with screen.

The original display content in the enlarged and displayed zone of treating that view-finder is chosen will be presented in the imaging screen with predetermined magnification ratio (enlargement factor); Should be scheduled to enlargement factor by the initial enlarged and displayed multiple of Zoom lens system according to the existing automatic calculating and setting of screen content display resolution; The screen that contrast resolution is high more then can be provided with higher initial enlarged and displayed multiple.In addition, above-mentioned predetermined enlargement factor also can dispose and be stored in the terminal by the user as required, and when practical operation, the user can select to call local existing magnification ratio configuration, carries out enlarged and displayed by imaging screen according to this magnification ratio.

Zoom lens system shows in imaging screen when amplifying content that the form that specifically can adopt pixel to amplify shows that the form that perhaps adopts the extraction character font to amplify shows.

Below above-mentioned dual mode is set forth in detail:

As shown in Figure 7, if the form that adopts pixel to amplify shows that the original display content in the enlarged and displayed zone of treating that above-mentioned steps S102 chooses view-finder comprises with the step that predetermined magnification ratio is presented in the imaging screen:

Step S1021 adopts interpolation algorithm to amplify with predetermined magnification ratio each pixel in the view-finder, and calculates the position coordinates of each pixel in imaging screen after amplifying;

Step S1022 shows the respective coordinates position of each pixel in imaging screen after amplifying.

Particularly, this mode is that the level amplification according to pixels of the original image in view-finder back is shown in imaging screen.The pixel value of the target pixel points after each amplifies on the imaging screen obtains after being calculated by predetermined interpolation interpolator arithmetic by the pixel value of original image vegetarian refreshments in the view-finder, then in the target pixel points that shows one by one on the imaging screen after amplifying.Interpolator arithmetic in the present embodiment specifically adopts the quadratic interpolation algorithm, and its principle is following:

Quadratic interpolation algorithm described herein is: to the target pixel points corresponding pixel value after amplifying on the imaging screen; Obtain desirable pixel coordinate corresponding in the view-finder by the coordinate Mapping algorithm computation; This coordinate is generally floating number and non-integer, with the pixel value of four adjacent nearest rounded coordinate pixels corresponding around this floating-point coordinate as going into ginseng, and these four different weights of pixel pixel values correspondence; If the horizontal coordinate of this pixel is near more apart from the horizontal coordinate distance of ideal coordinates; Then select bigger horizontal weights value,, then select bigger vertical weight value if the vertical coordinate of this pixel is near more apart from the vertical coordinate distance of ideal coordinates; Then by with the pixel value of these four pixels and corresponding level and vertical direction weighted value as going into to join, calculate the pixel value of imaging screen target pixel points.Specific algorithm is following:

As shown in Figure 8, Fig. 8 is a kind of amplification display method of the content in the view-finder on imaging screen in the present embodiment.If the screen coordinate that the original image vegetarian refreshments in the view-finder is corresponding be (i, j), i and j are integer; The corresponding screen coordinate of target pixel points after amplifying on the imaging screen be (x, y), x and y are integer; (m n) is pixel (x, the desirable pixel position on the view-finder that y) obtains by the coordinate Mapping relation function of imaging screen and view-finder on the imaging screen; M and n possibly be that integer also maybe decimal, the coordinate Mapping relation function of imaging screen and view-finder be f (x, y).And the pixel value of establishing on the imaging screen target pixel points after amplifying be T (x, y), on the view-finder pixel value of original image vegetarian refreshments be S (x, y).

Here be the reference frame initial point with the screen lower left corner, the upper right side, the view-finder center that is centered close to of imaging screen is example, then (m; N)=f (x, y)=(x/p-p0, y/h-h0); P is the enlargement factor of horizontal direction; H is the enlargement factor of vertical direction, and p0 is view-finder central point and imaging screen central point pixel range difference in the horizontal direction, and h0 is the pixel range difference of view-finder central point and imaging screen central point in the vertical direction.For the target pixel points on any imaging screen (x, y), the floating-point coordinate that can calculate its corresponding desirable pixel in view-finder through above-mentioned coordinate system mapping relations for (m, n)=(i+u, j+v); I wherein, j is an integer, u, v are [0,1] interval floating number; The pixel value T of the target pixel points after then amplifying on the imaging screen (x, y) can be by coordinate in the view-finder (i, j), (i+1, j); (i, j+1), (i+1, the pixel value of four original image vegetarian refreshments j+1) is united definite, and the weight proportion coefficient of establishing horizontal direction is hw0; Hw1, then the weight proportion coefficient of vertical direction is vw0, vw1, the pixel value T of the target pixel points after then amplifying on the imaging screen (x, y)=hw0*vw0*S (i; J)+and hw0*vw1*S (i, j+1)+hw1*vw0*S (i+1, j)+hw1*vw1*S (i+1, j+1).If set hw0=1-u in the present embodiment, hw1=u, vw0=1-v, vw1=v, so T (x, y)=(1-u) * (1-v) * S (i, j)+(1-u) * v*S (i, j+1)+u* (1-v) * S (i+1, j)+u*v*S (i+1, j+1).。

As shown in Figure 9, extract the form demonstration that character font amplifies if adopt, the original display content in the enlarged and displayed zone of treating that above-mentioned steps S102 chooses view-finder comprises with the step that predetermined magnification ratio is presented in the imaging screen:

Step S1023 calls the terminal operating system function, from terminal screen character display buffering, extracts the character in the screen coordinate scope of view-finder overlay area;

Step S1024 amplifies the character in the above-mentioned view-finder overlay area screen coordinate scope of extracting with predetermined magnification ratio;

Step S1025 is presented at the character after amplifying in the imaging screen.

Particularly, shown in figure 10, Figure 10 is the another kind of amplification display method of the content in the view-finder on imaging screen in the present embodiment.This mode is after the original character in the view-finder is extracted, and in imaging screen, shows after font is amplified again.At first Zoom lens system calls the terminal operating system function, from terminal screen character display buffering, extracts the character in the screen coordinate scope of view-finder overlay area.When the view-finder zone was rectangle, the coordinate of the screen area that this zone is corresponding was that (right, bottom), (left top) is the upper left corner coordinate of rectangular area.(right bottom) is its lower right corner coordinate.Zoom lens system calls the terminal operating system function; Cushioning, the corresponding character display in this rectangular area from screen extracts character; And into internal memory copied in the character after will extracting; Then character is shown in imaging screen according to the font of amplifying again, and can select any character in the imaging screen, operation such as copy.

In addition, in the practical implementation process, also can the frame figure layer of view-finder and imaging screen be shown with predetermined width and transparency; The profile of the screen original display content that is blocked that view-finder and/or imaging screen institute overlay area is corresponding carries out virtualization with preset transparency and shows.

Particularly, like Figure 11 and shown in Figure 12, Figure 11 and Figure 12 are view-finder and the translucent virtualization demonstration of imaging screen overlay area screen original contents synoptic diagram in the present embodiment.Zone in the frame of view-finder is a user's interest content to be amplified; The corresponding screen original display content in institute overlay area below view-finder and the imaging screen; Its corresponding pixel adopts smooth algorithm and shows with pre-set transparency; Make in the content of user after the clear amplification of seeing on the imaging screen being shown, can also see the general profile of the screen original contents that is covered below view-finder and the imaging screen.

In addition, shown in figure 13, Figure 13 is in the one embodiment of the invention, and handheld terminal screen Zoom lens system view-finder is the display mode synoptic diagram of display bezel only.The screen original contents that be blocked behind the view-finder this moment does not show that the screen original contents that is blocked behind the imaging screen still virtualization shows.

When virtualization shows; Pixel by the screen original contents in the screen original contents zone that imaging screen covered shows by original scale; And show by the pre-set transparency of user; The pixel stack of the content after the amplification that shows on these pixels and the imaging screen shows, guarantees that the user in the content, still can see the profile of the part original contents that is blocked simultaneously on seeing imaging screen.
