Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, hereinafter will be described in detail to embodiments of the invention by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
Embodiment of the method
Embodiment one
In one embodiment of the present of invention, disclose a kind of method that preview interface selection area amplifies, as shown in Figure 1, comprising:
Taking pictures or camera function unlatching of S01, terminal, and after showing preview interface on the touchscreen, detect the touch operation of user in preview interface.
When concrete operations, first-selection will start taking pictures or camera function of terminal, after startup, the touch-screen of terminal can show preview interface, user can carry out the operation of defined area on the touchscreen, present embodiment discloses a kind of method that preview interface selection area amplifies, namely, detect user's push on the touchscreen and lift operation, record push and lift operation coordinate on the touchscreen, with the upper left side of touch-screen for co-ordinate zero point, when and described push is different with lifting operation coordinate on the touchscreen time, with this coordinate line of 2 for diagonal line, form rectangular area, the length of this rectangular area is │ X1-X0 │, width is │ Y1-Y0 │, wherein (X1, Y1) for lifting the coordinate of operation, (X0, Y0) be the coordinate (true origin in following all embodiments is the screen upper left corner) of push.
In addition, can also work as described push different with lifting operation coordinate on the touchscreen time, using the coordinate of push as the center of circle, with this coordinate line of 2 for radius, formed border circular areas, the radius of this circle is
wherein (X2, Y2) coordinate that is push, (X3, Y3) is for lifting the coordinate of operation..
When user needs defined area, only need to carry out on the touchscreen scribing operation and can form a rectangle or a circular region, handled easily, the figure certainly drawn in this way, is not limited only to rectangle and circle shape, also can form other shapes.Equally, other operations except scribing operation also can be used to determine defined area.
S02, when after the touch operation defined area of user in preview interface being detected, according to the displaying contents of scale amplifying defined area preset.
According to the coefficient that user is arranged in advance in setting options, or according to factory preset coefficient, such as: 2 times or 4 times, determined defined area content is amplified.If the region delimited is rectangle, then with the central point of rectangle for focus, such as, the horizontal ordinate at the center, rectangular area in S01 is (X1-X0)/2, and ordinate is (Y1-Y0)/2, focuses.If the region delimited is for circular, then with the center of circle of circle for focus, such as, the coordinate in the center of circle in S01 is (X1, Y1), focuses.
S03, by amplify after displaying contents show in touch-screen preview interface.
To amplify and the defined area content of focusing shows in the superiors of preview interface.After defined area is exaggerated and is presented at the preview interface the superiors, if user wants the initial interface of getting back to preview, the region outside the defined area of amplifying display can be touched.Namely, after terminal detects user's push again on the touchscreen and lifts operation, judge that whether the coordinate lifting operation and push is amplifying outside the defined area shown, and if so, then returns to original interface by the preview interface on touch-screen.Certainly, other also can be set and trigger the method recovering original interface.
Illustrate with Fig. 6, Fig. 7 and Fig. 8 below, Fig. 6 is original preview interface, interface there is A and B, now, if user wants the A amplifying the screen upper left corner, the region at A place can be delimited, as shown in Figure 7, pre-setting or Default Value according to user, supposes that amplification coefficient is 2, displaying contents by the region at A place amplifies 2 times, and Fig. 8 is the schematic diagram of display after the content in the region at A place is amplified.
Embodiment two
Present embodiment discloses a kind of method that preview interface selection area amplifies, as shown in Figure 2, comprising:
Taking pictures or camera function unlatching of S11, terminal, and after showing preview interface on the touchscreen, detect the touch operation of user in preview interface.
S12, when after the touch operation defined area of user in preview interface being detected, according to preset ratio amplify defined area displaying contents and store.
The key distinction of the present embodiment and embodiment one is, after the content of institute defined area is amplified by the present embodiment, direct imaging also stores, that is: amplify user defined area and take pictures, then returning preview interface, waits other operations pending.
Embodiment three
Present embodiment discloses a kind of method that preview interface selection area amplifies, the basis of the above embodiments one implemented, namely the region after the amplification in embodiment one is moved, the functions such as focusing, as shown in Figure 3, comprising:
S101, detect described be exaggerated after described defined area in whether have touch operation.
User is preferably the operation of amplifying in rear region:
After user's push on the touchscreen being detected and lifting operation, record described push and lift operation coordinate on the touchscreen, judge that the coordinate of push is whether in the defined area be exaggerated of the superiors' display, if so, then determine there is touch operation in the described defined area of user after described being exaggerated.
S102, detect and have touch operation in the described defined area after described being exaggerated after, then according to the deformation trace of described touch operation, mobile described be exaggerated after described defined area, or according to the point of touch operation, centered by described point, focus.
During practical operation, if having touch operation in the described defined area of user after described being exaggerated, judge further described push and whether lift operation coordinate on the touchscreen identical; If so, then determine that this touch operation is single-click operation, centered by the coordinate of this click-point, focus; If not, then determine that this touch operation is slide, record described push and lift all coordinates in operating process, determine the deformation trace of slide, move the defined area after being exaggerated with this deformation trace, as shown in Figure 9.Such as: detect user's push on the touchscreen and lift operation, record push coordinate (X4, Y4) and lift operation coordinate (X5, Y5), first judging whether X4 equals X5, and whether Y4 equals Y5, if so, with (X4, Y4) or (X5, Y5) for focus, focus, if not, then record from (X4, Y4) (X5 is moved to, Y5) all in process coordinates, and form a motion track, described defined area synchronizing moving with it, such as: in S01, if defined area is rectangle, then the coordinate of push is (X0, Y0), relative to motion track, coordinate (the X0 of push, Y0) [X0+ (X5-X4) is moved to, Y0+ (Y5-Y4)], in like manner, lift the coordinate (X1 of operation, Y1) [X1+ (X5-X4) is moved to, Y1+ (Y5-Y4)], the rectangular area surrounded with these two coordinate points is again for defined area, for amplifying and showing, as shown in Figure 10.
