Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the embodiment of the present invention provides a kind of process flow diagram of method of video scaling, and the executive agent of the method is terminal, and this terminal possesses touch screen functionality, and wherein, this terminal can be mobile phone, panel computer etc.The method comprises the following steps:
Video is that a series of static images are presented as continuous picture by the various technology by adopting electric signal mode to be caught, note down, process, store, transmit and reappear.Continuous image change is per second exceedes 24 frame pictures when above, and according to persistence of vision principle, human eye cannot be distinguished the tableaux of single width, so look it is level and smooth continuous visual effect.
The first operation is for determining contact point, the central point in this contact point region that to be user obtain when contacting display screen, the irregular area that this region can obtain by finger contact terminal for user, the regular domain that also can obtain by equipment contact terminals such as capacitance pens.The first operation can be determined a contact point, or the first operation can be determined two contact points.
Video Layer is for the data of store video.What conventionally show at display screen is the figure layer after Video Layer and figure map overlay.Wherein, figure figure layer is for storing the data of title block, the data of toolbar and the data of frame etc. of control video.
The second operation is for determining the convergent-divergent multiple of the first video.In the present embodiment, second operates the direction moving according to contact point, and determines the convergent-divergent multiple of the first video according to the air line distance of the two-end-point of at least one sliding trace.
Optionally, when the second operation is with the starting point of this sliding trace, while slip away from the direction of basic point, second is operating as amplifieroperation; When the second operation is with the starting point of this sliding trace, while slip near the direction of basic point, second is operating as reduction operation.
Optionally, when the second operation is with the starting point of the sliding trace of maximum length, while slip away from the direction of the central point between the second contact point and the line of the 3rd contact point formation, second is operating as amplifieroperation; When the second operation is with the starting point of the sliding trace of maximum length, while slip near the direction of the central point between the second contact point and the line of the 3rd contact point formation, second is operating as reduction operation.
In the time that contact point is one, the central point in the region that user obtains when display screen by contact is contact point, the irregular area that this region can obtain by finger contact terminal for user, also can be the regular domain obtaining by equipment contact terminals such as capacitance pens, this contact point be first make contact.The central point in another region that user obtains by contact display screen is in addition the 4th contact point.Wherein, by the continuous movement of the 4th contact point, obtain sliding trace.During taking first make contact as basic point, when user contacts terminal display, and while sliding the 4th contact point with direction away from first make contact, the first video amplifier, obtains the second video; When user contacts terminal display, and to connect near the direction of first make contact while sliding the 4th contact point, the first video dwindles, and obtains the second video.
It should be noted that, in the time sliding the 4th contact point operation, user contacts the invariant position that display screen keeps first make contact all the time.
For example, user pins with finger (as forefinger) region that the first video need to amplify, and the central point in the region of this amplification is first make contact.In the time that another finger (as middle finger) contact terminal display of user obtains the 4th contact point, when user slides the 4th contact point with the direction away from first make contact, the first video amplifies taking first make contact as basic point, obtain the second video, wherein, the second video is to amplify the first video afterwards; In the time that another finger contact terminal display of user obtains the 4th contact point, when user slides the 4th contact point with the direction near contact point, the first video dwindles taking first make contact as basic point, obtains the second video, wherein, the second video is to dwindle the first video afterwards.
In the time that contact point is two, user obtains two regions by contact when display screen, and the central point in two regions is respectively the second contact point and the 3rd contact point here.Wherein, by the continuous movement of the second contact point and the 3rd contact point, obtain two sliding traces respectively.Taking the central point between the second contact point and the line of the 3rd contact point formation as basic point, when user contacts terminal display, and when the second contact point and the 3rd contact point are slided with the direction away from this basic point, the first video amplifier, obtains the second video simultaneously; When user contacts terminal display, and when the second contact point and the 3rd contact point being slided near the direction of this basic point, the first video dwindles, and obtains the second video simultaneously.
For example, user contacts with two fingers (as forefinger and middle finger) region that the first video need to amplify simultaneously, the central point that two fingers contact respectively two irregular areas of the display screen at the first video place is two contact points, the central point in the region that the central point between the line that two contact points form is this amplification.When two fingers of user contact terminal display simultaneously, and while sliding with the direction away from central point, the first video amplifies taking central point as basic point simultaneously, obtains the second video; When two fingers of user contact terminal display simultaneously, and when sliding near the direction of central point, the first video dwindles taking central point as basic point, obtains the second video simultaneously.
In the time that the second size is greater than first size, illustrate that the second video is to amplify the first video afterwards.Point centered by basic point, intercepts the second video by first size, thereby obtains the 3rd video.Wherein, first size and the second size are length and are multiplied by wide rectangle, and unit is pixel.
In the time that contact point is one, determine that first make contact is basic point; Or,
In the time that contact point is two, determine that the central point between the second contact point and the line of the 3rd contact point formation is basic point.
For example, user amplifies the first video, what on Video Layer, show is the second video, what on the display screen of this terminal, show is point centered by basic point, thereby by first size, the second video is intercepted the 3rd video obtaining, what on the display screen of terminal, show is the part of the second video.
In the time that the second size is not more than first size, illustrate that the second video is to dwindle the first video afterwards.On the display screen of terminal, directly show the second video, on the display screen of terminal, show the first video after dwindling.
For example, in the time that the second size is less than first size, due to the first video of high-resolution terminal plays low resolution, may cause the first video playback fuzzy, user can be by dwindling the first video, thereby can watch the first video clearly.Or, in the time that the second size equals first size, illustrate that user reduces the first video after amplifying, after reduction, user can watch the full content of the first video.
It should be noted that, step 104 and step 105 are relations arranged side by side, and both can not carry out simultaneously.In accompanying drawing 1, with empty wire frame representation step 105, or also can be with empty wire frame representation step 104, wherein this step of empty wire frame representation is optional step, can certainly otherwise represent optional relation, the embodiment of the present invention is not carried out the mode of the optional relation of restricted representation.
The embodiment of the present invention provides a kind of method of video scaling, by the time showing the first video, receives the first operation, determines contact point at Video Layer according to described the first operation; Receive the second operation, determine the convergent-divergent multiple of described the first video according to described the second operation; According to the convergent-divergent multiple of described the first video, described the first video is carried out to convergent-divergent, obtain the second video, wherein, the size of the display screen that described first size is described terminal, described second is of a size of the size of described the second video; In the time that described the second size is greater than described first size, according to described contact point, described first size and described the second video, obtains and show the 3rd video; In the time that described the second size is not more than described first size, show described the second video.The embodiment of the present invention has solved in prior art the restriction due to the screen resolution of mobile communication equipment, while making to play high-resolution video in the mobile communication equipment of low resolution, the problem that can not amplify this video, while having solved the video of playing low resolution in high-resolution mobile communication equipment simultaneously, can not dwindle this video, cause the problem that video pictures is fuzzy, realized to displaying video carry out part amplify or entirety dwindle, improved the sharpness of displaying video picture.
As shown in Figure 2, the embodiment of the present invention provides the process flow diagram of the method for another kind of video scaling, and the executive agent of the method is terminal, and this terminal possesses touch screen functionality, and wherein, this terminal can be mobile phone, panel computer etc.The method comprises the following steps:
Step 201, in the time showing the first video, terminal receives the first operation, determines the contact point of default number on Video Layer according to the first operation;
Video Layer is for the data of store video.What conventionally show at display screen is the figure layer after Video Layer and figure map overlay.Wherein, figure figure layer is for storing the data of title block, the data of toolbar and the data of frame etc. of control video.
The first operation is for determining contact point, and in the time that the first operation comprises a child-operation, the first operation is for determining the operation of first make contact at the first video; In the time that the first operation comprises two child-operations, the first operation is for determining the operation of the second contact point and the 3rd contact point at the first video.
In the time that contact point is first make contact, contact terminal according to the first operation by user and obtain first area, then according to first area, the central point of determining first area is first make contact.The irregular area that first area can obtain by finger contact terminal for user, the regular domain that also can obtain by equipment contact terminals such as capacitance pens.
In the time that contact point is the second contact point and the 3rd contact point, determine contact point according to the first operation, obtain respectively second area and the 3rd region that user contacts terminal, then according to second area, the central point of determining second area is the second contact point, and according to the 3rd region, the central point of determining the 3rd region is the 3rd contact point, it should be noted that, second area is identical with the acquisition pattern of first area with the 3rd acquisition pattern in region, specifically can, referring to the acquisition pattern of first area, not repeat one by one at this.For example, in the time that user contacts terminal display (as user can pass through finger contact terminal display, this finger can be forefinger), what terminal received is the irregular area that user contacts display screen, then determines that according to this irregular area the central point of this irregular area is first make contact.
In the time that user contacts two irregular areas of terminal display simultaneously (as user can pass through two finger contact terminal displays, these two fingers can be forefinger and middle finger), what terminal received is two irregular areas that user contacts display screen, then determines that according to one of them irregular area the central point of this irregular area is the second contact point; Determine that according to another irregular area the central point of this irregular area is the 3rd contact point.
Concrete, as shown in Figure 3, show the first video 303 at the display screen 301 of terminal.
Wherein, in the time that contact point is one, determine that first make contact is basic point 302; Or, in the time that contact point is two, determine that the central point between the second contact point and the line of the 3rd contact point formation is basic point 302.
Step 202, in the time that contact point is one, on Video Layer, terminal receives the second operation, determines the convergent-divergent multiple of the first video according to the second operation;
In the time that contact point is one, illustrate that this contact point is first make contact.
As shown in Figure 4, while determining the convergent-divergent multiple of the first video according to the second operation, comprise the following steps:
The second operation is amplified the first video or dwindles the first video for determining, and determines the convergent-divergent multiple of the first video.
This sliding trace is the motion track of the 4th contact point; In the present embodiment, the first operation is also for determining the 4th contact point; Terminal contacts the 4th region of terminal according to the first operation acquisition user, then determine that according to the 4th region four-range central point is the 4th contact point, it should be noted that, by the continuous movement of the 4th contact point, obtains sliding trace.
For example, after terminal receives first make contact, when another finger (as middle finger) of user contacts terminal display, what terminal received is an irregular area of user's finger contacts display screen, then determines that according to this irregular area the central point of this irregular area is the 4th contact point.After terminal receives the 4th contact point, user uses finger sliding terminal display, thereby forms the motion track of one article of the 4th contact point, thereby this motion track is the sliding trace that terminal is obtained by the continuous movement of the 4th contact point.
It should be noted that, when first make contact determine after, and second operation carry out time, first operation remain unchanged.For example, in the time that the central point of the first area of user's forefinger contact display screen is first make contact, needs user's forefinger to be permanently connected to display screen, and can not change the position of first make contact, until after the first video scaling completes, user's forefinger just can leave display screen.
Because user manually carries out the slide of the 4th contact point, making sliding trace is not straight line, and terminal need to be determined the bee-line between sliding trace two-end-point, the air line distance of the two-end-point that this bee-line is sliding trace.
Air line distance is directly proportional to the convergent-divergent multiple of the first video.When the sliding trace of the 4th contact point is larger, illustrate that this air line distance is larger, the convergent-divergent multiple of the first video is larger.In the present embodiment, in the time of one millimeter of the every increase of air line distance, the convergent-divergent multiple of the first video increases by 2 times.Certainly, do not limit the ratio of the convergent-divergent multiple of terminal to air line distance and the first video, also can work as one millimeter of the every increase of air line distance time, the convergent-divergent multiple of the first video increases by 3 times or 4 times etc.
For example, after the sliding trace that terminal reception user slides on terminal display by middle finger, terminal determines that the air line distance length of the two-end-point of this sliding trace is 3 millimeters, 6 times of the first video scalings.
After determining the convergent-divergent multiple of the first video, continue execution step 203.
Step 203, in the time that contact point is two, on Video Layer, terminal receives the second operation, determines the convergent-divergent multiple of the first video according to the second operation;
In the time that contact point is two, illustrate that this contact point is the second contact point and the 3rd contact point.
As shown in Figure 5, while determining the convergent-divergent multiple of the first video according to the second operation, comprise the following steps:
The effect of this second operation is identical with the effect of the operation of second in step 401.
One of them sliding trace is the motion track of the second contact point, and another sliding trace is the motion track of the 3rd contact point.It should be noted that, by the continuous movement of the second contact point and the 3rd contact point, obtain two sliding traces respectively.For example, after terminal receives the second contact point and the 3rd contact point simultaneously, be after user contacts terminal display by two fingers (as forefinger and middle finger) simultaneously, user points simultaneously in the enterprising line slip of terminal display with two, thereby form two sliding traces, now terminal receives this two sliding traces.After the first video scaling completes, two fingers of user can leave terminal display.
Because user manually carries out the slide of the second contact point and the slide of the 3rd contact point, making two sliding traces is not all straight line, and the length of two sliding traces is not necessarily identical, terminal need to be determined the sliding trace of maximum length in two sliding traces, determine the bee-line between this sliding trace two-end-point, the air line distance of the two-end-point that this bee-line is sliding trace according to the sliding trace of maximum length.
Air line distance is directly proportional to the convergent-divergent multiple of the first video.In the time that sliding trace is larger, illustrate that this air line distance is larger, the convergent-divergent multiple of the first video is larger.
After determining the convergent-divergent multiple of the first video, continue execution step 204.
It should be noted that, step 202 and step 203 are relations arranged side by side, and both can not carry out simultaneously.In accompanying drawing 2, with empty wire frame representation step 203, or also can be with empty wire frame representation step 202, wherein this step of empty wire frame representation is optional step, can certainly otherwise represent optional relation, the embodiment of the present invention is not carried out the mode of the optional relation of restricted representation.
Step 204, according to the first video scaling multiple of determining, terminal is carried out convergent-divergent to the first video on Video Layer, obtains the second video;
As shown in Figure 6, terminal is carried out convergent-divergent to the first video on Video Layer, obtains the second video 601;
The invariant position of basic point 602 in the second video 601.
The second video 601 is that terminal is carried out convergent-divergent video afterwards according to convergent-divergent multiple to the first video.
In the time that contact point is one;
When the second starting point being operating as with sliding trace, while slip away from the direction of first make contact, the first video amplifies, thereby obtains the second video 601; When the second starting point being operating as with sliding trace, while slip near the direction of first make contact, the first video dwindles, thereby obtains the second video 601.
For example, receive after first make contact in terminal, user's forefinger contacts all the time terminal display and keeps the invariant position of forefinger, and then middle finger is when sliding away from the direction of forefinger, and the first video amplifies, thereby obtains the second video 601; After terminal receives first make contact, user's forefinger contacts all the time terminal display and keeps the invariant position of forefinger, and when then middle finger slides with the direction of close forefinger, the first video dwindles, thereby obtains the second video 601.
In the time that contact point is two;
When the second starting point being operating as with the sliding trace of maximum length, while slip away from the direction of the central point between the second contact point and the line of the 3rd contact point formation, the first video basic point amplifies, thereby obtains the second video 601; When the second starting point being operating as with sliding trace, when the direction between the line forming near the central point of the second contact point and the 3rd contact point is slided, the first video dwindles, thereby obtains the second video 601.
For example, after terminal receives the second contact point and the 3rd contact point, when user's forefinger and middle abutment terminal display and while sliding with contrary direction, the first video amplifies, thereby obtains the second video 601; When user's forefinger and middle abutment terminal display and while sliding with direction in opposite directions, the first video dwindles, thereby obtains the second video 601.
Step 205, in the time that the second size is greater than first size, according to contact point, first size and the second video, obtains the 3rd video;
As shown in Figure 7, in the time that the second size 701 is greater than first size 702, illustrate that the second video is to amplify the first video afterwards.Point centered by basic point 703, intercepts the second video according to first size 702, thereby obtains the 3rd video 704.
It should be noted that, the 3rd video 704 is parts of the second video, the size of the display screen that first size 702 is terminal, and the second size 701 is the size of the second video.
For example, due to high-resolution first video of device plays of low resolution, may cause the first video details to represent unintelligible, user amplifies the first video, what on Video Layer, show is the second video, what on the display screen of this terminal, show is point centered by basic point, thereby the second video is intercepted to the 3rd video 704 obtaining by first size 702, and the 3rd video 704 showing on the display screen of terminal is parts of the second video.
Step 206, in the time that the second size is not more than first size, shows the second video;
As shown in Figure 8, in the time that the second size 801 is less than first size 803, illustrate that the second video is to dwindle the first video afterwards, wherein, the position of basic point 802 remains unchanged.
On the display screen of terminal, directly show the second video, on the display screen of terminal, show the first video after dwindling.
As shown in Figure 9, in the time that the second size 801 equals first size 803, illustrate that the second video is the video after reduction, terminal is to the first video amplifier, then the first video amplifying is narrowed down to original size.The position of basic point 802 remains unchanged.
It should be noted that, the second size 801 equals first size 803, but in order to distinguish clearly first size 803 and the second size 801, expression in the drawings does not overlap first size 803 with the second size 801.
For example, in the time that the second size 801 is less than first size 803, due to the first video of high-resolution terminal plays low resolution, may cause the first video playback fuzzy, user can be by dwindling the first video, thereby can watch the first video clearly.Or, in the time that the second size 801 equals first size 803, illustrate that user reduces the first video after amplifying, after reduction, user can watch the full content of the first video.
It should be noted that, step 205 and step 206 are relations arranged side by side, and both can not carry out simultaneously.In accompanying drawing 2, with empty wire frame representation step 206, or also can be with empty wire frame representation step 205, wherein this step of empty wire frame representation is optional step, can certainly otherwise represent optional relation, the embodiment of the present invention is not carried out the mode of the optional relation of restricted representation.
Step 207, obtains the first figure layer by Video Layer and figure map overlay, and terminal is projected in this first figure layer in display screen, to show the second video or the 3rd video in this first figure layer at display screen.
When the first video is carried out to amplifieroperation, point centered by basic point, determines the 3rd video at Video Layer, then Video Layer and figure map overlay is obtained to the first figure layer, the first figure layer is projected in display screen, to show the 3rd video in the first figure layer at display screen;
When the first video is carried out to reduction operation, determine the second video at Video Layer, then Video Layer and figure map overlay are obtained to the first figure layer, the first figure layer is projected in display screen, to show the second video in the first figure layer at display screen.
The method of a kind of video scaling that the embodiment of the present invention provides, can realize in the time that the mobile communication equipment of low resolution is play high-resolution video or the video in high-resolution mobile communication equipment broadcasting low resolution, can carry out convergent-divergent to the video of playing, the first video of realizing playing carries out local amplification or the overall operation of dwindling, thereby reaches the object of clear displaying video picture.
