In order to be illustrated more clearly in the technical scheme of the embodiment of the invention, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is a touch-screen schematic diagram of the prior art;
A kind of flow chart of choosing the method in focusing zone that Fig. 2 provides for the embodiment of the invention;
A kind of schematic representation of apparatus that Fig. 3 provides for the embodiment of the invention with camera function.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The embodiment of the invention is applied to the technology of touch-screen on the camera head, and the user can instruct input by touch screen, to the camera head operation of focusing more accurately.For ease of understanding, describe below in conjunction with the implementation procedure of accompanying drawing to the embodiment of the invention.
As shown in Figure 2, a kind of method of choosing the focusing zone comprises:
Particularly, the figure input signal can be end to end curve; Perhaps, also can be the curve that joins substantially from beginning to end, at this moment, can also handle the corresponding end to end curve of acquisition according to the first point of curve and the position of end point.
The user watches the picture on the screen, draws a curve with hand or felt pen on screen then, and the image section that will focus is enclosed in the curve.
Particularly, the area in focusing zone can perhaps, also can be equal to or slightly less than the area that the figure input signal covers greater than the area of figure input signal covering;
Further, the focusing zone can be rectangle or circle, and rectangle can be rectangle or square;
Further, the focusing zone that generates figure input signal correspondence be rectangle method can for: to the lateral separation of a rightmost some length of side as rectangle, the fore-and-aft distance of point that arrives the top with the point bottom in the described figure input signal overlay area is as another length of side of rectangle with the leftmost point in the described figure input signal overlay area;
Particularly, can set up a rectangular coordinate system on screen, be the origin of coordinates with the point in the touch-screen lower left corner, with screen the horizontal line of below be transverse axis, direction is the longitudinal axis with the vertical curve of the left of screen to the right, direction is upwards set up coordinate.Obtain the ordinate Y1 of the abscissa X2 of the abscissa X1 of the leftmost point of figure input signal overlay area, rightmost point, point bottom and the ordinate Y2 of point topmost, choose four point (X1, Y1), (X1, Y2), (X2, Y1), (X2 Y2) as the coordinate at four angles of rectangle, can obtain a rectangle by said method.
When the focusing zone that generates figure input signal correspondence be rectangle, can regulate the length of rectangle or wide, for example increase the length of rectangle or the width of increase rectangle, make the length of rectangle and wide ratio equal the length of touch-screen and wide ratio.
The focusing zone that generates figure input signal correspondence be circle method can for: with the mid point of the point-to-point transmission line segment farthest of the distance in the figure input signal overlay area initial point, with the diameter of distance between two points as circle as circle.
The focusing zone that generates figure input signal correspondence can also be oval or other shape.
After the step in the focusing zone that generates described figure input signal correspondence, image in the focusing zone can also be presented on the screen, the user can determine to carry out preview before the focus image, and whether decision carries out following operation still regenerates the focusing zone.
Can focus to the image in the zone of focusing, and image is presented on the screen, prepare to take.The focusing technology comprises optical focusing technology and digital focusing technology.The optical focusing technology is by changing the focus of camera lens.General optical lens has two eyeglasses, changes focus by changing two distances between the eyeglass.Numeral focusing technology is meant the focus of not passing through to change camera lens, and the purpose that the data bitmap of lens imaging reaches focusing is amplified, dwindled to the mode of directly amplifying, dwindling with picture.
The method of choosing the focusing zone that provides by the embodiment of the invention described above as can be seen, the user can accurately focus by the screen that touches camera head, focusing, it is more convenient, directly perceived to operate.
A kind of device that the embodiment of the invention also provides with camera function, as shown in Figure 3, the implementation structure of this device specifically can comprise:
The figure input signal can be end to end curve.The user watches the picture on the screen, draws a curve with hand or felt pen on screen then, and the image section that will focus is enclosed in the curve, and signal receiving module 1 receives curve signal, and curve signal is sent to the regional generation module 2 of focusing;
The regional generation module 2 of focusing is used to generate the focusing zone of figure input signal correspondence;
Particularly, the area in focusing zone can also can be equal to or slightly less than the area that the figure input signal covers greater than the area of figure input signal covering.The focusing zone can be rectangle or circle, and rectangle can be rectangle or square.
If generate when the focusing of described figure input signal correspondence is regional to be rectangle, arrive the length of side of the lateral separation of rightmost point with the leftmost point in the described figure input signal overlay area, arrive the fore-and-aft distance of point topmost another length of side as described rectangle with the point bottom in the described figure input signal overlay area as described rectangle.
If the focusing zone that generates described figure input signal correspondence is when circular, with the mid point of the distance point-to-point transmission line segment farthest in the described figure input signal overlay area initial point as described circle, with the diameter of described distance between two points as described circle.
Focusing Executive Module 3 is used for carrying out the focusing operation according to the focusing zone that the regional generation module 2 of focusing generates.
Can focus to the image in the zone of focusing, and image is presented on the screen, prepare to take.
The device that provides by the embodiment of the invention described above as can be seen, the user can accurately focus by the screen that touches camera head, focusing, it is more convenient, directly perceived to operate.
One of ordinary skill in the art will appreciate that all or part of flow process that realizes in the foregoing description method, be to instruct relevant hardware to finish by computer program, described program can be stored in the computer read/write memory medium, this program can comprise the flow process as the embodiment of above-mentioned each side method when carrying out.Wherein, described storage medium can be magnetic disc, CD, read-only storage memory body (Read-Only Memory, ROM) or at random store memory body (Random Access Memory, RAM) etc.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
