Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
The embodiment of the invention discloses a kind of image amplification display method and device, can be applied in and adopt Android (Android system, Mobile operating system under the *** house flag) etc. in the mobile terminal of operating system, by the mode of screen printing, the screen area that needs show is carried out amplifieroperation.
For example, when carrying out text operation, as modifying to the short message content of input.At first can need the word of modification by " long pressing ", magnifier occur, can occur the word of quilt " long pressing " and the content of near zone in magnifier, simultaneously, the cursor in text operation also can be moved to correspondence position and show in magnifier.When moveable finger on touch screen, cursor also can be followed movement, and the movement of cursor also can synchronously show in magnifier.Cursor can rest on the rearmost position of finger touch at last, then can select to wait text operation.
Introduce in detail a kind of image amplification display method disclosed by the invention and device below by enumerating several specific embodiments.
Embodiment one
Introduce in detail the disclosed a kind of image amplification display method of the embodiment of the present invention.
With reference to Fig. 1, show a kind of image amplification display method process flow diagram in the embodiment of the present invention.
Wherein, intercepting current screen image can be the full-screen image of intercepting current screen.
Step 102 determines that according to the location coordinate information of the screen operator that detects needs amplify the screen area that shows.
Above-mentioned screen operator can comprise the screen operator of triggering mode, the screen operator of gesture mode, based on the screen operator of cursor and the screen operator of voice mode etc.
Can acquire the location coordinate information of screen operator by application programming interface (Application Programming Interface, the API) function that system provides.
Step 104 is amplified demonstration with the above-mentioned screen picture that needs to amplify the screen area that shows.
The above-mentioned screen area that need to amplify shows can be in the text editing zone, and is too small or text font is too small and easily produce the zone etc. of maloperation due to screen size.For example, the text message of having inputted is updated, cursor in the text editing zone need to be navigated to the text message place that need to update, size restriction due to screen size or text font, the operation easier of positioning cursor is larger, so the residing screen area of text message that needs can be updated amplifies demonstration, the residing screen area of text message that is equivalent to needs are updated shows in magnifier.
Detailed needs amplify the screen area that shows and can determine according to amplification display shape and the amplification demonstration multiple of actual set, as showing screen area with 1.2 times of round-shaped amplifications, namely take the screen operator position as the center of circle, take the pixel that sets in advance or length as diameter or radius, by corresponding image Processing Interface, as the canvas interface of Android system, the current screen image that intercepting is obtained amplifies 1.2 times and shows.
In sum, the disclosed a kind of image amplification display method of the embodiment of the present invention is compared with background technology, has the following advantages:
Mode by intercepting current screen image realizes the image amplifying display function, can reduce the consumption of system resource, and response image amplifies the operation that shows fast.
Embodiment two
Introduce in detail the disclosed a kind of image amplification display method of the embodiment of the present invention.
With reference to Fig. 2, show a kind of image amplification display method process flow diagram in the embodiment of the present invention.
Step 200, the screen sensor information that judgement detects in advance and image are amplified demonstration demand broadcast message snoop results and whether are satisfied image amplification display condition.
Preferably, above-mentioned image amplification display condition can comprise: exist simultaneously screen operator and image to amplify demonstration demand broadcast message.
Above-mentioned screen sensor information can be for detecting information on touch screen.For example, by the screen sensor information that the point touching screen produces, comprise click, double-click or long by etc. the screen sensor information that produces of operation.
Preferably, above-mentioned screen sensor information can comprise the location coordinate information of screen operator.
Wherein, above-mentioned screen operator and the image of existing simultaneously amplifies demonstration demand broadcast message, can comprise:

Substep 2042 is defined as needing to amplify with the screen area centered by above-mentioned correspondence position the screen area that shows.
For example, the screen area centered by above-mentioned some A ' is defined as the screen area that need to amplify shows, simultaneously, the scope, the display shape that need to amplify the screen area that shows can also be set as required, and the parameter such as enlargement factor.
Step 206 is amplified demonstration with the above-mentioned screen picture that needs to amplify the screen area that shows.
Demonstration can be amplified according to difformity in the above-mentioned amplifying display screen curtain zone of needing, if amplify demonstration according to circle, above rheme can be set to the center of circle, and the border circular areas that required demonstration size is diameter amplifies the screen area that shows as needs.
In Android system, the Canvas interface that can provide by system amplifies specified multiple to the above-mentioned screen picture that needs to amplify the screen area that shows, amplifies demonstration as 1.2 times, realizes the content at amplifying display screen curtain operating position place.
Step 208, when the location coordinate information of above-mentioned screen operator changes, again intercept the current screen image and above-mentioned location coordinate information is changed after the needs screen picture that amplifies the screen area that shows amplify demonstration.
When the location coordinate information of screen operator changes, the expression screen operator situation that is moved, need to again intercept the current screen image this moment, changes with this content that reflects that cursor and needs amplify the screen area of demonstration.
In sum, the disclosed a kind of image amplification display method of the embodiment of the present invention is compared with background technology, has the following advantages:
At first, realize the image amplifying display function by the mode that intercepts the current screen image, can reduce the consumption of system resource, response image amplifies the operation that shows fast.
Secondly, realize that image amplifies demonstration and needs to use image to amplify the module that the module that shows belongs to Different Logic, has improved efficient and stability that the image amplification shows.
Again, the screen picture of optional position intercepting arbitrary levels that can be on screen has guaranteed that image amplifies the dirigibility that shows.
