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.
Introduce the video call method that the embodiment of the invention provides earlier, Fig. 1 has described the embodiment of video call method provided by the invention, what this embodiment described is the handling process of video telephone in the video call process, video telephone obtains the video that the video calling opposite end sends by the video transmission passage of setting up, and this embodiment comprises:
101, obtain the required parameter of the first area that needs to strengthen demonstration in video first two field picture, described first area is the subregion of determining in described video first two field picture.
Wherein, strengthen showing it can is to amplify to show, also can be with higher definition demonstration etc.
The first area that needs to strengthen demonstration in video first two field picture can be regular figure or non-regular figure, and wherein regular figure can be rectangle, square, circle etc.In the embodiment of the invention, required parameter is the parameter sets that can directly determine the video area, comprises the position vector parameter, and the position vector parameter specifically can be information such as position coordinates.Wherein, when being regular figure in the first area, the required parameter that obtains is less, and for example when this regular figure was rectangle or square, the position coordinates that only needs this rectangle or foursquare two diagonal angles was as required parameter; At this regular figure when being circular, only need the position coordinates in this circular center of circle and radius that should circle or diameter as required parameter.
Fig. 2 a has described the schematic diagram of the first area of display screen demonstration, shown in Fig. 2 a, the current demonstration of display screen of video telephone be video first two field picture 201 that video calling opposite end camera obtains, the user need amplify demonstration to the first area in video first two field picture 201, thereby need to determine the first area 202 of amplification, in Fig. 2 a, the first area 202 that needs to amplify is rectangles, therefore the required parameter that needs to determine can be two position coordinateses to an A and B of the first area 202 of rectangle, promptly the required parameter of Que Dinging is A (x1, y1), B (x2, y2), A (x1, y1) the expression position coordinates of A point in video first two field picture 201 wherein, B (x2, y2) position coordinates of expression B point in video first two field picture 201.
Wherein, in one embodiment of the invention, the parameter of being obtained is by the first area of user in the operation selection of touch-screen, this first area is converted to the required parameter of first area again.
In another embodiment of the present invention, the parameter of being obtained is to utilize external writing pen in the first area that touch-screen is selected by the user, the first area is converted to the required parameter of first area again.
In another embodiment of the present invention, the parameter of being obtained is the first area of adopting the mode of button input digit to select by the user, again the first area is converted to the required parameter of first area, in the present embodiment, preestablish some regular magnification region figures in the video telephone, when the user when set to need amplifying or need the first area of clear demonstration, by the first area figure of selecting to set in advance, and take to drag or the mode of sliding is controlled the size of first area, and then the first area selected of definite end user.
In another embodiment of the present invention, the parameter of being obtained is that the needs of selecting from the parameter of preserving in advance amplify the required parameter of the first area that shows.
In one embodiment of the invention, after the first area is converted to the required parameter of first area, can further preserve the required parameter that conversion obtains, thereby when carrying out video calling with this video calling opposite end once more, do not need to select the first area once more, and directly use the required parameter of preserving, so not only reduce user's operation, also reduce the conversion operations that video telephone need carry out, improve the processing speed of video telephone, also improve user's operating experience.
102, send required parameter to the video calling opposite end.
In video call process, especially in point-to-point communication process, an end that carries out video calling is called the video calling opposite end of the video calling other end.
Be appreciated that when video calling for point during to the pattern of multiple spot, promptly when a video calling end was transferred to the video flowing of local terminal at a plurality of video calling end, at this moment a plurality of video calling ends can be described as the video calling opposite end of the video calling end of transmitting video-frequency flow.
In one embodiment of the invention, the parametric form of required parameter with Session initiation Protocol (SIP:Session Initiation Protocol) message can be sent to the video calling opposite end;
In another embodiment of the present invention, the parametric form of required parameter with RTCP Real-time Transport Control Protocol (RTCP:Real-time Transport Control Protocol) message can be sent to the video calling opposite end.
103, receiver, video conversation opposite end is by video second two field picture of video transmission passage transmission, and video second two field picture is handled by camera according to required parameter by the video calling opposite end and obtained.
Wherein, because the video transmission passage of transmission of video second two field picture is identical with the video transmission passage of transmission of video first two field picture, so the overall bandwidth of transmitting video data remains unchanged.
104, show video second two field picture that receives.
In one embodiment of the invention, video second two field picture is obtained corresponding digital coding by the video calling opposite end, and corresponding data are the data corresponding with required parameter in the data of camera collection.
Fig. 2 b has described the schematic diagram of the first area of display screen demonstration, and shown in Fig. 2 b, display screen is current to be video second two field picture of full screen display, promptly is that the amplification that carry out the first area in video first two field picture 202 is shown.
In another embodiment of the present invention, the resolution of the picture material of the first area of corresponding video second two field picture is higher than the resolution of picture material of the first area of corresponding video first two field picture, therefore when display video second two field picture, the definition of the first area of corresponding video second two field picture will be higher than the definition of the first area of corresponding video first two field picture, thereby improves the display resolution that needs to strengthen the first area that shows.
From the above, video telephone is by obtaining the required parameter of the first area that needs to strengthen demonstration in video first two field picture in the present embodiment, and this required parameter sent to the opposite end, make the opposite end send video second two field picture corresponding by data transmission channel with required parameter, thereby the video corresponding with the first area second two field picture is shown, realize the enhancing of first area picture material is shown.
Fig. 3 has described another embodiment of video call method provided by the invention, what this embodiment described is the handling process of video telephone in the video call process, video telephone sends video by the video transmission passage of setting up to the video calling opposite end, and this embodiment comprises:
