In a specific embodiment, after the writing pen of mobile device is pulled out, eject dialog box in the touch-screen of mobile device, user can carry out clicking entering Images uniting pattern.
Under this Images uniting pattern, touch-screen can be divided into two layer, thus allows the image shown on the touchscreen can be presented in different layer, and user chooses image in different layer, last composograph, thus composograph can be generated in real time.Following step can be described in detail this.
102, obtain the first image being shown in the first layer in touch-screen, then enter step 103.
This first image can be taken for post-positioned pick-up head.When program is taken pictures in operation, described processor controls described post-positioned pick-up head and opens; Also the first image can be made to be front-facing camera shooting by setting, under this kind of situation, when program is taken pictures in operation, described processor controls front-facing camera and opens.
In addition, the photo that also can select in photograph album for user of the first image.When selecting photo, processor accepts the instruction that user triggers on the touchscreen, and transfers this photo in memory, and then shows in touch-screen.
103, obtain described writing pen and be drawn on person's handwriting on described touch-screen being shown in the second layer in touch-screen, then enter step 104.
Wherein, the second layer is positioned at the top of the first layer.When showing, the image of the second layer is be suspended in the image on the first layer.
Specifically, when processor obtains the person's handwriting of writing pen drafting:
The contact coordinate data of described writing pen are reached described processor by touch-screen;
Contact coordinate data described in described processor for recording, and according to described contact coordinate data, person's handwriting is shown in described touch-screen in real time; Wherein, the single contact touch-screen of writing pen is wall scroll person's handwriting to leaving the person's handwriting drawn between touch-screen.
104, one of closed area selecting person's handwriting to generate is as view-finder.
In this step 104, specifically comprise the following steps:
1041, according to the described person's handwriting drawn, judge the closed area close with described person's handwriting, and described closed area is shown in touch-screen.
Need to illustrate in this step, in processor, prestore multiple closed area.The plurality of closed area, when off-duty takes pictures program, is stored in the memory of mobile device.After entering the program of taking pictures, read by processor and call;
During embody rule, the multiple closed areas prestored in processor, comprising: the predefined closed area of mobile device, and the closed area that user draws.
When judging the closed area close with person's handwriting, such as user depicts a horizontal line, processor automatic decision, and judge that there are square, pentagon, rectangle, hexagon, triangle etc. in the closed area close with this horizontal line, and be shown in the form of a list in touch-screen, click selection for user.
When judging the closed area close with person's handwriting, processor in real time according to the person's handwriting that user draws, can judge close closed area and is shown in touch-screen.Such as user is after depicting a horizontal line, and continue again to depict an oblique line with a certain end points of this horizontal line, then processor judges that close closed area has: triangle, parallelogram etc., and renewal is shown in touch-screen.
1042, judge whether the select command receiving user, if so, then enter step 1044; If not, then show not exist in processor the closed area that user wants, then processor performs step 1043, to realize the person's handwriting drawn according to user, the closed area that automatic decision generates.
1043, judge whether complete person's handwriting is drawn, and if so, then enters step 1045; If not, then step 103 is returned.
Specifically, if processor does not obtain the contact coordinate data of described writing pen within the first threshold time of setting, then judge that person's handwriting is drawn complete.Wherein, this first threshold time can sets itself, such as 15 seconds, 20 seconds etc.
1044, using the closed area chosen as view-finder, then enter step 105.
1045, identify whether the closed area that person's handwriting is formed is at least one; If so, step 1046 is entered; If not, step 1047 is entered.
1046, choose in this closed area one as view-finder, then enter step 105.
More specifically, when person's handwriting forms more than one closed area, described processor chooses in this closed area one as view-finder, see Fig. 3, specifically comprises:
A1, calculate the area Si of each closed area, and draw the area S of maximum closed area
max, then enter step a2; Wherein, it is N number of for forming closed area, i=1 ~ N, and N is greater than 1.

max, then enter step a3.
A3, calculate the focus point g of each focus point gi and maximum closed area
maxair line distance Ti, then enter step a4.
A4, calculate the weighted average α i of each closed area, then enter step a5.Wherein, α i=Si/S
max* p-Ti*q, p and q are weight coefficient, and are all greater than 0.
This weight coefficient is empirical value, needs the numerical value that comes out through investigation and testing evaluation, can according to actual conditions sets itself, the present embodiment just will not enumerate.
A5, the maximum α chosen in weighted average α i
max, judge α
maxwhether be greater than the Weighted Threshold of setting; If so, step a6 is entered; If not, step a7 is entered.
A6, selection α
maxcorresponding closed area is view-finder;
A7, select maximum closed area S
maxcorresponding closed area is view-finder.
When selecting view-finder, if there is the more than one closed area satisfied condition, then user is pointed out to select one of them closed area as view-finder.
Further, it should be noted that, after view-finder is chosen, the image that person's handwriting is formed overall can be moved to suitable position by user in the second layer, and can not carry out cutting to the first image in the first layer.
Alternatively, after processor selection view-finder, processor can also give the person's handwriting forming view-finder colouring automatically, see Fig. 4, comprises step b1 ~ b3:
B1, processor calculate the average tone s of the first layer outside view-finder, then enter step b2;
B2, processor obtain the contrary tone t of tone s average with this from palette, then enter step b3;
B3, processor this tone t gives the person's handwriting forming view-finder colouring.
1047, point out user failure, and wait for person's handwriting input next time, then return step 103.
If processor does not receive person's handwriting within the Second Threshold time continued, then control mobile device and exit Images uniting pattern.This Second Threshold time can sets itself, such as 5 minutes, 10 minutes etc.
105, in the scope of described view-finder, obtain the second image, then enter step 106.
This second image can be taken for front-facing camera.After view-finder chosen by processor, notify that described front-facing camera is opened; Also can take for post-positioned pick-up head.
It should be noted that, the first image and the second image can be respectively post-positioned pick-up head and front-facing camera shooting herein, but can not be the shooting of same camera simultaneously.When realizing, processor enter take pictures program time, can select to open one of them camera (being generally post-positioned pick-up head), then after the complete view-finder of follow-up selection, open another camera, to ensure the camera shooting that the first image and the second image are respectively different.
In addition, alternatively, the picture that also can select in mobile device photograph album for user of this second image, during concrete operations, after view-finder is selected, in touch-screen, show the dialog box of ejection, processor acquisition user clicks order, opens photograph album and selects picture by user.
