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, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
First introduce the video call method that the embodiment of the present invention provides, 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 video call process, video telephone obtains by the transmission of video passage of setting up the video that the video calling opposite end sends, and this embodiment comprises:
101, obtain in video the first two field picture the required parameter that needs to strengthen the first area shown, described first area is definite subregion in described video the first two field picture.
Wherein, strengthen showing it can is to amplify to show, can be also with higher definition demonstration etc.
In video the first two field picture, needing to strengthen the first area shown can be regular figure or irregular figure, and wherein regular figure can be rectangle, square, circle etc.In the embodiment of the present invention, required parameter is can directly determine the parameter sets of video area to comprise the position vector parameter, and the position vector parameter can be specifically the information such as position coordinates.Wherein, while in first area, being regular figure, the required parameter obtained is less, for example, when this regular figure is rectangle or square, only needs the position coordinates at this rectangle or foursquare two diagonal angles as required parameter; At this regular figure while being circular, only need the position coordinates in this circular center of circle and this circular radius or diameter as required parameter.
Fig. 2 a has described the schematic diagram of the first area of display screen demonstration, as shown in Figure 2 a, the current demonstration of display screen of video telephone be video the first two field picture 201 that video calling opposite end camera obtains, the user need to amplify demonstration to the first area in video the first two field picture 201, thereby determine and need the first area 202 of amplifying, in Fig. 2 a, needing the first area 202 of amplifying is rectangle, therefore needing definite required parameter can be two position coordinateses to an A and B of the first area 202 of rectangle, definite required parameter is A (x1, y1), B (x2, y2), A (x1 wherein, y1) mean the position coordinates of A point in video the first two field picture 201, B (x2, y2) mean the position coordinates of B point in video the first two field picture 201.
Wherein, in one embodiment of the invention, the parameter of obtaining is the first area of selecting in the operation of touch-screen by the user, then this first area is converted to the required parameter of first area.
In another embodiment of the present invention, the parameter of obtaining is to utilize external writing pen to be converted to the required parameter of first area in the ，Zai Jiang first area, first area of touch-screen selection by the user.
In another embodiment of the present invention, the parameter of obtaining is the first area that adopts the mode of key-press input numeral to select by the user, again first area is converted to the required parameter of first area, in the present embodiment, preset some regular magnification region figures in video telephone, as the user when set to need amplifying or need the first area of clear demonstration, the first area figure set in advance by selection, and the mode of taking to drag or slide controls 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 obtaining is that the needs of selecting from the parameter of pre-save amplify the required parameter of the first area shown.
In one embodiment of the invention, after first area is converted to the required parameter of first area, can further preserve the required parameter that conversion obtains, thereby when again with this video calling opposite end, carrying out video calling, do not need again to select first area, and directly use the required parameter of preserving, so not only reduce user's operation, also reduce the conversion operations that video telephone need to carry out, improve the processing speed of video telephone, also improve user's operating experience.
102, send request 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 is point-to-multipoint pattern,, when a video calling end is given a plurality of video calling end by the video streaming of local terminal, 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, required parameter can be sent to the video calling opposite end by the parametric form with Session initiation Protocol (SIP:Session Initiation Protocol) message;
In another embodiment of the present invention, required parameter can be sent to the video calling opposite end by the parametric form with RTCP Real-time Transport Control Protocol (RTCP:Real-time Transport Control Protocol) message.
103, video the second two field picture that receiver, video conversation opposite end sends by the transmission of video passage, video the second two field picture is processed acquisition according to required parameter by camera by the video calling opposite end.
Wherein, because the transmission of video passage of transmission of video the second two field picture is identical with the transmission of video passage of transmission of video the first two field picture, so the overall bandwidth of transmitting video data remains unchanged.
104, show video the second two field picture received.
In one embodiment of the invention, video the second two field picture is obtained corresponding data encoding by the video calling opposite end, data corresponding with required parameter in the data that corresponding data are camera collection.
Fig. 2 b has described the schematic diagram of the first area of display screen demonstration, and as shown in Figure 2 b, display screen is current is video second two field picture of full screen display, is that the amplification that the first area 202 in video the first two field picture is carried out shows.
In another embodiment of the present invention, the resolution of the picture material of the first area of corresponding video the second two field picture is higher than the resolution of the picture material of the first area of corresponding video the first two field picture, therefore when display video the second two field picture, the definition of the first area of corresponding video the second two field picture will be higher than the definition of the first area of corresponding video the first two field picture, thereby improves the display resolution that needs to strengthen the first area shown.
From the above, in the present embodiment, video telephone is by obtaining in video the first two field picture the required parameter that needs to strengthen the first area shown, and this required parameter is sent to opposite end, make opposite end send the video corresponding with required parameter the second two field picture by data transmission channel, thereby the video corresponding with first area the 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 video call process, video telephone sends video by the transmission of video passage of setting up to the video calling opposite end, this embodiment comprises:
301, receive the required parameter that needs to strengthen the first area shown in video the first two field picture that opposite end sends, first area is definite subregion in video the first two field picture.
302, process and obtain video the second two field picture by camera according to required parameter.
