Embodiment

Below, be described in detail for the preferred embodiments of the present invention with reference to accompanying drawing.

And the following description is taking smart mobile phone as example, but the present invention is not limited thereto, can be applicable to panel computer, personal digital assistant (PDA), notebook computer, desktop computer, handheld device etc.

In this manual, use the terms such as " first ", " second ", " for the first time ", " for the second time " to be described, but these terms are not for limiting or restriction the present invention, being only used to make those skilled in the art to understand rapidly the present invention.

In step S100, after screenshotss state being detected, user's chosen area is carried out for the first time screenshotss and preserved the first screenshotss picture.

In the present embodiment, screenshotss operation is divided into two kinds of processing modes.One is panorama interception way, intercepts whole image content.After portable terminal receives user's the operational order of panorama screen printing, intercept the full screen content of current demonstration, and preserve (or interim buffer memory) with the form of picture.

Another kind is local screenshotss mode, intercepts the partial picture content of portable terminal.After portable terminal detects screenshotss state, detect user's input, to determine screenshotss region, in the time that user's input meets predetermined condition, carry out local screenshotss and preserve (or interim buffer memory) with the form of picture.

Particularly, as shown in Figure 5, described step S100 can also comprise the steps: after screenshotss state being detected, detect the first contact A from user, on screen, construct the frame of reference (S102) using the first contact A as true origin (x=0, y=0); Detect the second contact B from user, calculate the coordinate figure (x1, y1) of the second contact B (S104); In the time that the coordinate figure difference of the second contact B and the first contact A meets predetermined condition, carry out for the first time screenshotss and preserve the first screenshotss picture (S106).

By local screenshotss mode, can only intercept the needed content of user, therefore user, without first intercepted panoramic picture as in the past after, intercepts topography again by special application program.Especially,, while needing to splice screenshotss picture, can omit the process of the unnecessary contents such as the frame that all can occur in the every Zhang Quanjing screenshotss of cutting picture in portable terminal.

Now, user can produce contact by various input mediums on the screen of portable terminal, for example, can utilize the touches such as finger, pointer, or utilizes mouse click etc.At this, can also comprise the step of proofreading and correct for user's input.

And, in the time detecting the contact of user's generation, in the coordinate figure that calculates each contact, can also record the generation time of contact.

Preferably, the coordinate figure of each contact can be the pixel value on screen.

In step S106 step, as each coordinate difference (△ x1 of the second contact B and the first contact A, △ y1) be all not equal to 0 or the absolute value of each coordinate difference (be for example greater than predetermined value, 0.5) time, can be judged as the region that user has selected wanted screenshotss, carry out thus a screenshotss operation.Now, can on screen, show and treat screenshotss region (with reference to the dotted line in figure 2a) based on the first contact and the second contact, to point out user.

In the past, under screenshotss state, screen, by locked, automatically shields the incoming events such as touch screen, therefore after carrying out a screenshotss operation, need to exit screenshotss state, and carry out page turning or slip screen, and then enter screenshotss state and carry out screenshotss, or after entering screenshotss state, carry out in the given time repeatedly screenshotss, the former be needs repeatedly screenshotss or splicing snapshot as time all very loaded down with trivial details, the latter splice snapshot as time very loaded down with trivial details.

In the present invention, after step S100 carries out screenshotss, enter step S110, detect in the given time and whether have the sliding screen operation that exceeds threshold value from user's sliding distance, in the time that existence in the schedule time exceeds the sliding screen operation of threshold value from user's sliding distance, being judged as user will carry out screenshotss again, enters step S120, with the picture that slides.Now, in step S120, can also mark be set in the bottom of screenshotss picture for the first time.

The sliding screen operation that described sliding distance exceeds threshold value refers to that the distance of the slide that user inputs reaches the last time pixels across (width) of screenshotss picture (or screenshotss region) or the threshold value of vertical pixel (highly).Preferably, this threshold value be last time screenshotss picture width or height 90~100%.; after screenshotss operation for the first time; user be more than or equal to for the sliding screen operation of any one direction (upper and lower, left and right) of screen screenshotss region last time width, height 90% time; can be judged as user and will carry out again screenshotss operation, thereby remove locking to screen and respond user's sliding screen operation.

The described schedule time can be set voluntarily by user, for example, can be set as 0.5 second, 1 second etc.

In addition, the result of described step S110, in the time not existing from more than user's preset range sliding screen operation in the schedule time, the screenshotss that can be judged as user finish and exit screenshotss state (S112).

Described mark can be that described the second contact B can be also the framework that covers certain limit.Now, the second contact B or framework in the time that picture slides, cannot exceed screen indication range and within being limited in screen.The object that mark is set to framework is, the multiple snapshots of splicing as time, can be applicable to the matching strategy of two images, improve accuracy rate and the efficiency of splicing.

Then,, in step S130, user's chosen area is carried out for the second time screenshotss and preserved the second screenshotss picture.

Now, as shown in Figure 6, step S130 can also comprise the steps: to construct relative coordinate system (S132) taking described the second contact B as initial point (x`1, y`1); Detect the 3rd contact C from user, calculate the coordinate figure (x2, y2) of the 3rd contact C in relative coordinate system (S134); In the time that the coordinate difference of the 3rd contact C and the second contact B meets predetermined condition, carry out for the second time screenshotss and preserve the second screenshotss picture (S136).

Now, in the time detecting the contact of user's generation, in the coordinate figure that calculates each contact, can also record the generation time of contact.

In step S136 step, as each coordinate difference (△ x2 of the 3rd contact C and the second contact B, △ y2) be all not equal to 0 or the absolute value of each coordinate difference (be for example greater than predetermined value, 0.5) time, can be judged as the region that user has selected wanted screenshotss, carry out thus a screenshotss operation.Now, can on screen, show and treat screenshotss region (with reference to the dotted line in figure 2a) based on the second contact and the 3rd contact, to point out user.

In addition, in step S132, when the described framework that is labeled as (with reference to Fig. 3 a) time, can be using the upper summit B` of this framework as initial point (b) be constructed relative coordinate system with reference to Fig. 3.

Although be to construct relative coordinate system taking the second contact as initial point in the present embodiment, the present invention is not limited thereto, that is, still can use the frame of reference taking the first contact as initial point to carry out various operations.

Now, can omit the step S132 for constructing relative coordinate system, and in step S134, directly calculate the coordinate figure of the 3rd contact in the frame of reference.

Then, in step S140, splicing the first screenshotss picture and the second screenshotss picture.Preferably, now based on described Sign mosaics the first screenshotss picture and the second screenshotss picture.

Preferably, in the time splicing, can be using the generation time of each contact as variable uses, to improve accuracy rate and the efficiency of splicing.

Now, as shown in Figure 7, step S140 can also comprise: image pre-treatment step (S142), image registration step (S144), set up transformation model step (S146), unified coordinate transform step (S148), merge reconstruction step (S150).

In image pre-treatment step (S142), for the first screenshotss picture and the second screenshotss picture, using the first screenshotss picture as with reference to image, and using the second screenshotss picture as image to be spliced, carry out the basic operation of Digital Image Processing such as removing noise, edge extracting, histogram processing, and set up the matching template of image and image is converted to (Fourier transform, wavelet transformation etc.).

In image registration step (S144), adopt predetermined matching strategy, find out template or the corresponding position of unique point in reference picture in image to be spliced, and then complete the alignment between image.

Now, the mark such as the second contact or framework can be used as unique point.Accordingly, predetermined matching strategy can be based on reference picture and image to be spliced the second contact or framework.

Setting up in transformation model step (S146), according to the corresponding relation between template or unique point, calculate the parameters value in mathematical model, set up thus the mathematic(al) manipulation model of two width images.

In unified coordinate transform step (S148), according to the mathematic(al) manipulation model of setting up, image to be spliced is transformed in the coordinate system (, the frame of reference) of reference picture, complete unified coordinate transform.

Now, the coordinate figure of each contact of relative coordinate system can be transformed to the coordinate figure of the frame of reference, by multiple contacts, image to be spliced be transformed into the frame of reference thus.

For example, the first contact A is (0 at the coordinate figure of the frame of reference, 0), the second contact B is (x1 at the coordinate figure of the frame of reference, y1), the 3rd contact C at the coordinate figure taking the second contact B as the relative coordinate system of initial point as (x2, y2), now the 3rd contact C is (x2-x1, y2-y1) at the coordinate of the frame of reference.

But, when the operation of screenshotss is repeatedly all while carrying out in the frame of reference taking the first contact as initial point, do not need to carry out the process of coordinate conversion.

Merging in reconstruction step (S150), the overlapping region of stitching image is merged, obtain splicing the smooth and seamless panoramic picture of reconstruct.

That is, complete at image under the condition of registration, carry out the associated fusion treatment of pixel with reference to image with image to be spliced, thus two Image Mosaics are become one there is no the picture of redundant information and be shown to user.

Although in above explanation, be illustrated for the example of carrying out twice screenshots and splicing two pictures, those skilled in the art should know, the situation that above-described embodiment can be applicable to repeatedly screenshotss and splices multiple pictures.Now, described step S110 to S130 can carry out repeatedly, and carries out splicing repeatedly in splicing step.

Fig. 8 is according to the block scheme of the portable terminal of the embodiment of the present invention.

Can comprise according to portable terminal of the present invention: display unit 100, positioning unit 110, screenshotss unit 120, indexing unit 130, storage unit 140, concatenation unit 150.

Display unit 100, the screen content of demonstration portable terminal.

Positioning unit 110, detects the operation of user for the screen of described portable terminal, selected screenshotss region.This positioning unit 110 can be applicable to part (selectivity) screenshotss mode, is applied to the local screen's content that intercepts portable terminal.After screenshotss state being detected, positioning unit 110 detects user's input, to determine screenshotss region.In the present embodiment, positioning unit 110 adopts two point location methods, utilizes the selected screenshotss of the coordinate figure difference region of two reference point on screen, and two reference point on screen can be the contacts that user produces, and can be also the reference points that system is specified.

For example, after screenshotss state being detected, positioning unit 110 detects the first contact A from user, constructs the frame of reference using the first contact A as true origin (x=0, y=0) on screen.Subsequently, positioning unit 110 detects the second contact B from user, and calculates the coordinate figure (x1, y1) of the second contact B, thus the selected local screenshotss of coordinate difference x1-x, the y1-y based on the first contact A and the second contact B region.

In the time of positioning unit 110 selected screenshotss region, display unit 100 can demonstrate information (for example, the dotted line frame of Fig. 2 a), to point out user to be about to carry out the region of screenshotss.

Now, the input of positioning unit 110 all right correcting users.; when touch-screen operation by the lower input medium of the degree of accuracy such as finger; unavoidably the position of each contact is touched in screen content part, and now positioning unit 110 can be proofreaied and correct and (near the frame of screen) current collector laterally the position of contact.

Screenshotss unit 120, based on the selected screenshotss region of described positioning unit 110, carries out screenshotss.

,, in the time that the selected screenshotss region of positioning unit 110 meets predetermined condition, screenshotss unit 120 carries out local screenshotss and preserves (or interim buffer memory) to storage unit 140 with the form of picture.

For example, as each coordinate difference (△ x1 of the second contact B and the first contact A, △ y1) be all not equal to 0 or the absolute value of each coordinate difference (be for example greater than predetermined value, 0.5) time, screenshotss unit 120 can be judged as user has selected the region of wanted screenshotss, carries out thus a screenshotss operation.

And, after often completing a screenshotss operation, screenshotss unit 120 detects whether there is the sliding screen operation that exceeds threshold value from user's sliding distance in the given time, when there not being the sliding screen operation that exceeds threshold value from user's sliding distance in the schedule time, exit screenshotss state, and in the time that existence in the schedule time exceeds the sliding screen operation of threshold value from user's sliding distance, screenshotss unit 120 can be judged as user will carry out screenshotss operation again and wait for positioning unit 110 selected screenshotss regions.

So, need to carry out more than screenshotss when operation once when being judged as user, indexing unit 130 can last time carry out predetermined mark on screenshotss picture, benchmark when this mark can be used as screenshotss next time.

Described mark can be that described the second contact B can be also the framework that covers certain limit.Now, the second contact B or framework in the time that picture slides, cannot exceed screen indication range and within being limited in screen.

After indexing unit 130 carries out predetermined mark on screenshotss picture last time, positioning unit 110 can, using a summit on mark as reference point, be constructed relative coordinate system, and detect the 3rd contact from user.

Now, when described while being labeled as described the second contact B, positioning unit 110 can be constructed the relative coordinate system taking the second contact B as initial point, and when described in while being labeled as framework, positioning unit 110 can be constructed relative coordinate system as initial point using the upper summit B` of this framework.

Positioning unit 110 is in the time the 3rd contact C being detected, the coordinate figure of the 3rd contact C based in relative coordinate system, selected local screenshotss region, and screenshotss unit 120 is while meeting predetermined condition in the selected screenshotss region of positioning unit 110, carries out again local screenshotss and preserve (or interim buffer memory) to storage unit 140 with the form of picture.

Now, the present invention can also comprise timing unit (not shown), with in the time detecting the contact that user produces, records the generation time of contact, and records the screenshotss time when screenshotss each time in screenshotss unit 120.

Storage unit 140, for preserving the repeatedly screenshotss picture from screenshotss unit 120.

Concatenation unit 150, for splicing the multiple screenshotss pictures in described storage unit 140.Preferably, concatenation unit 150 can be based on the multiple screenshotss pictures of described Sign mosaics.

As shown in Figure 9, concatenation unit 150 comprises image pretreatment module 151, image registration module 152, MBM 153, coordinate transformation module 154, image co-registration module 155.

Image pretreatment module 151, for multiple screenshotss pictures, based on screenshotss time of origin, using last screenshotss picture as with reference to image, a rear screenshotss picture, as image to be spliced, is carried out various pre-service (denoising, edge extracting, conversion etc.).

Image registration module 152, adopts predetermined matching strategy, find out in image to be spliced described in be marked at the correspondence position of reference picture, carry out the alignment between image.

MBM 153, according to the corresponding relation of described mark, calculates the parameters value in mathematical model, sets up thus the mathematic(al) manipulation model of two width images.

Coordinate transformation module 154, the mathematic(al) manipulation model of setting up according to MBM 153, is transformed into image to be spliced in the coordinate system (, the frame of reference) of reference picture, completes unified coordinate transform.

Now, coordinate transformation module 154 is transformed to the coordinate figure of each contact of relative coordinate system the coordinate figure of the frame of reference, by multiple contacts, image to be spliced is transformed into the frame of reference thus.

Image co-registration module 155, based on mark, merges with reference to image and image to be spliced., the mark (coincide point or coincidence framework) in reference picture and image to be spliced is merged.

That is, complete at image under the condition of registration, carry out the associated fusion treatment of pixel with reference to image with image to be spliced, thus two Image Mosaics are become one there is no the picture of redundant information and be shown to user.
