Referring to Fig. 2, it is the flow chart according to the caption presentation method of the embodiment of the invention.Present embodiment is shown as example with captions in the change TV and describes, and specifically comprises
The information in above-mentioned picture-display-region territory comprises the position of demonstration and the wide high information of picture;
Step 202 obtains the information in non-picture-display-region territory;
The information in above-mentioned non-picture-display-region territory comprises the position of demonstration and the wide high information of picture; For example, a kind of possible account form is following:
Obtain the output resolution ratio Wtv*Htv of screen; The output resolution ratio of TV for example;
Obtain the aspect ratio r of current broadcast film; For example aspect ratio is 2.35: 1;
Calculate the wide height in non-picture-display-region territory in the screen according to the output resolution ratio of said screen and the aspect ratio of current broadcast film.Wide height to calculate non-picture-display-region territory, screen below is an example, and a kind of possible computational methods are: from { 0, Wtv-(Htv-Wtv/r)/the wide of 2} point beginning is Wtv, and height is the zone of (Htv-Wtv/r)/2.
For example, output resolution ratio is the HDTV of 1080*1920, and when playing the film of 2:35:1, following black surround zone be that to put wide 1920 height that begin from (0,968) be 130 zone.
Step 203 reads the information of first captions to be shown;
The information of above-mentioned first captions comprises the position of demonstration and the wide high information of captions;
Step 204 if judging said first captions is presented at said picture-display-region territory, is then adjusted said first captions, obtains second captions;
Being appreciated that above-mentioned first captions can be presented on the screen, also can be not to be presented on the screen.
Step 205 is presented at non-picture-display-region territory with adjusted said second captions.
Need to prove that captions to be shown are called first captions before above-mentioned will the adjustment, and adjusted captions are called second captions.
Here, can adopt the method for cutting row to the adjustment that captions carry out, can also adopt the method for convergent-divergent, the method that can also adopt cutting row and convergent-divergent to combine specifies respectively below.
If adopt the method for cutting row, then said first captions to be adjusted, the step that adjusted said second captions is presented at said non-picture-display-region territory comprises:
I) as if wide high information, know first captions to be shown, then said first captions to be shown cut by line number that the captions after the cutting are reconfigured, and execution in step ii) then greater than delegation according to first captions to be shown; If know that captions to be shown are delegation, then can directly show;
Whether the height of ii) judging the captions after said the reconfiguring greater than the height in non-picture-display-region territory in the said screen, if, then execution in step iii) otherwise, execution in step is iv);
Iii) said captions are cut by line number once more, the captions after the cutting are reconfigured, execution in step ii) afterwards;
Second captions after iv) will reconfiguring are presented at non-picture-display-region territory.
The above-mentioned method of cutting and reconfiguring by row is prior art, is example with a kind of possible implementation method only here, describes.
Suppose that the picture captions are two row, then the process by the row cutting can be:
Whether the color of from the first capable delegation to the end, being had a few in every row in identification and the recording caption picture is identical;
Begin to be designated as h0 from captions first row to the line number at first non-same color rows (being to have a few in the delegation not to be same color) place; Begin to same color first row (promptly next first row of the next one from h0; The color of being had a few is all identical in this first row) the place line number is designated as h1, can know that then effective captions height zone is for capable of the capable zone of h1 since h0;
The line number that searches out next non-same color rows is designated as h2, and effective captions height zone of second row is since the capable zone of the capable h1-h0 of h2 so;
Therefore, can cutting arbitrarily in the zone from h1 to h2.Certainly,, there is more accurate algorithm to cut, no longer specifies here at which in field of image recognition in the zone of h1 to h2.
During demonstration, if guarantee h0 and h2 make up after finally with delegation.
Press columns when cutting in like manner.
Need to prove that above-mentioned only is a kind of possible implementation method, in practical application, also have other cutting implementation method, the embodiment of the invention does not limit concrete cutting method.
For example, the wide high information of captions to be shown is that the captions of the 70*360 of single file can directly show, wide high information is the two row captions of 140*500, can go to show after the cutting again; Be appreciated that if the above captions of triplex row are arranged, can carry out twice row cutting, all be data line with what guarantee to show at every turn, thereby guarantee on non-picture-display-region territory such as black surround, to show captions.
Referring to Fig. 3; It is according to the embodiment of the invention by the picture view after the row cutting; As can be seen from the figure, being originally after two capable captions reconfigure through cutting becomes delegation, like this; Delegation's captions after reconfiguring are the zone of the black surround below screen demonstration fully just, thereby has avoided the overlapping of captions and video pictures.
If adopt the method for convergent-divergent, then said first captions to be adjusted, the step that adjusted said second captions is presented at said non-picture-display-region territory comprises:
01) as if the wide high information according to first captions to be shown, know the height of the height of captions greater than non-picture-display-region territory in the said screen, then said first captions are carried out convergent-divergent, execution in step 02 then); If know first captions to be shown height, then can directly show smaller or equal to non-picture-display-region territory in the said screen;
Whether the height of 02) judging the captions behind the said convergent-divergent is greater than the height in non-picture-display-region territory in the said screen, if then execution in step 03) otherwise, execution in step 04);
03) said captions are carried out convergent-divergent once more, execution in step 02 afterwards);
04) second captions behind the convergent-divergent is presented at non-picture-display-region territory.
For example; The wide high information of captions to be shown is the captions of the 70*360 of single file; Can adopt (Htv-Wtv/r)/4 proportional zoom to show to 63*324, be the captions of the 140*500 of two row for the wide high information of captions to be shown, can adopt (Htv-Wtv/r)/2 proportional zoom to show to 126*450.
The method that adopts cutting row and convergent-divergent to combine is then adjusted said first captions, and the step that adjusted said second captions is presented at said non-picture-display-region territory comprises:
A) as if wide high information, know captions to be shown, then said first captions to be shown are cut by line number and convergent-divergent processing, then execution in step b) greater than delegation according to first captions to be shown; If know that first captions to be shown equal delegation, and captions to be shown then can directly show smaller or equal to the height in non-picture-display-region territory in the said screen;
Whether the height of b) judging the captions after said cutting and convergent-divergent are handled greater than the height in non-picture-display-region territory in the said screen, if, execution in step c then) otherwise, execution in step d);
C) said captions are cut and convergent-divergent processing, execution in step b afterwards once more);
Second captions that d) will cut after handling with convergent-divergent are presented at non-picture-display-region territory.
For example, the wide high information of captions to be shown is that the height of multirow (more than 3 row) is 210 captions, can adopt the high demonstration of (Htv-Wtv/r)/2 proportional zoom to 126, and the captions cutting back with the 3rd row shows simultaneously.
Need to prove that confirming of above-mentioned scaling only is an embodiment, in practical application, can adopt the whole bag of tricks to confirm as required, the application does not do qualification to definite method and definite great scaling of scaling.
Need to prove that the application embodiment may further include: the record scaling; All captions in the film are carried out convergent-divergent according to same scaling.The font size that can guarantee all pictures in the film like this is all identical, and little problem when big improves user experience when avoiding font.
Above-mentioned is to be that example describes with the picture captions, if in the video pictures be text subtitle, then processing method is simple relatively, is specially:
Calculate the wide height in non-picture-display-region territory in the screen; Concrete computational methods repeat no more with aforementioned identical;
Number of characters addition with every capable captions draws total number of characters;
Judge this total number of characters shows whether to exceed non-picture-display-region territory by delegation, otherwise, be about to adjusted captions by one and be presented at non-picture-display-region territory; If then, first display part second captions in non-picture-display-region territory show remaining second captions again after refreshing afterwards.
