A kind of method of changing background of video call, its special character is, comprises following steps:
1] user of Multimedia Mobile phone selects needed background video 1 from predefined a plurality of background videos;
2] user selects a background color 11;
3] user records one and is shooting background 21, is the filmed image 2 of the shooting body 22 with user with selected background color 11;
4] user starts video calling;
5] from filmed image 2, select the zone conduct identical or approximate to be replaced zone (23) with background color 11;
6] from background video, 1 select zone 12 as an alternative, the zone all identical with profile, replace being replaced in the filmed image 2 image in zone 23, formation replacement image 3 with the image of replacing zone 12 with the position that is replaced zone 23;
7] communication module sends and replaces image 3;
8] repeating step 5], step 6] and step 7], until end of conversation.
Above-mentioned steps 1] in background video 1 be picture or film.
Above-mentioned background image 1 is JPG, TIFF or PNG format picture.
Above-mentioned background image 1 is MOV, AVI or MPEG4 form film.
Above-mentioned steps 2] in background color 11 from palette or background video 1, select.
Above-mentioned steps 7] in communication module be the 3G communication module.
Above-mentioned steps 7] in communication module be the 3G communication module.
Advantage of the present invention is:
The foundation that the present invention uses background color to replace as a setting needs the zone that is replaced of changing by judging in the filmed image, change in the replacement zone of the background video of selecting in advance by the user.So the method for changing background of video call provided by the invention can reach the effect that the user's communication environment is maintained secrecy.
Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Fig. 1 is the flow chart of the method for changing background of video call of the present invention.
Fig. 2 is the relation of background video among the present invention, filmed image, replacement image and the forming process schematic diagram of replacing image.
Wherein: 1-background video, 11-background color, 12-are replaced the zone, the 2-filmed image, and the 21-shooting background, the 22-the shooting body, 23-is replaced the zone, and 3-replaces image, and 31-replaces the image background, and 32-replaces image body;
Step S1-selects background video;
Step S2-selects background color;

Step S5-selects the zone identical or approximate with background color to form from filmed image and is replaced the zone;
Step S6-replaces the zone that is replaced in the filmed image with formation replacement image with the relative position in the background video,
Step S7-utilizes communication module to send the replacement image,
Whether step S8-finishes video calling,
Step S9-finishes conversation.
Embodiment
Referring to Fig. 1, workflow of the present invention is: the background video (step S1) of selecting required change from the Multimedia Mobile phone in the background image that the user stores or downloads; The user selects a background color (step S2) from arbitrary image or in the colour table; The user is shooting background with the background color, is that the shooting body is recorded one section filmed image (step S3) with user oneself with the Multimedia Mobile phone; Record finish after, the user starts the video calling (step S4) with the other side; Graphics processing unit with zone identical in the filmed image with background color as being replaced zone (step S5); Graphics processing unit is selected zone as an alternative, the zone all identical with profile with the position that is replaced the zone from background video, the image with being replaced the zone in the image replacement filmed image of replacing the zone forms and replaces image (step S6); Mobile phone utilizes its inner communication module will replace sound, user voice and replacement image synchronized transmission another user side to video calling, better effects if when communication module is the 3G communication module (step S7); When mobile phone utilizes after communication module will replace another user side that image is sent to video calling, judge whether to finish video calling (step S8) at once; If conversation does not finish as yet, repeating step S5 to S7 continues filmed image is done the step of changing background of video call; Otherwise finish conversation (step S9).When selecting background video, background video can be the static images of forms such as the user JPG, the TIFF that take voluntarily or download, PNG, or the dynamic film of forms such as MOV, AVI, MPEG4.In Fig. 2, this background video is one and is formed dynamic film by several static images.
As shown in Figure 2, the user can be by selecting background color 11 on the display screen of Multimedia Mobile phone in colour table or the selected background video, effect is better when background color 11 is selected by any point in the background video 1, and its selection color is looked closely user's selection and decided.Promptly adopt the color that carries of the video background that the user selectes to be play, just when playing ceaselessly with the user's oneself that photographs image being added on original video frame by frame after treatment.
As shown in Figure 2, the user utilizes the camera on this Multimedia Mobile phone to record filmed image 2, and it is identical or be similar to the shooting background 21 and the shooting body 22 of background color 11 to comprise color in this filmed image 2.Promptly taking 2 o'clock at first Transparent color of selection in phone, require the shooting people to stand under the color identical with the Transparent color that is provided with then and take, the background colour that just can hide the shooting people during like this with the Background From Layer merging only stays the image of taking the people.
As shown in Figure 2, the graphics processing unit of mobile phone inside is done contrast to filmed image 2 and this background color 11 and is handled, and zone identical or approximate with background color 11 colors in the filmed image 2 is chosen out, forms and is replaced zone 23.
As shown in Figure 2, graphics processing unit will be selected to replacement zone 12 with respect to the band of position that is replaced zone 23 in the background video 1.Then, graphics processing unit replaces to replacement zone 12 with the zone 23 that is replaced in the filmed image 2, forms and replaces image 3.In fact, replace in the image 3 and comprise two zones: promptly replace image background 31 and replace image body 32, wherein, this replaces image background 31 and to replace zone 12 identical, and should replacement image body 32 identical with this shooting body 22.Both can take, and telephone user's picture of photographing was added on the background video, equally also can make one section earlier, to use when the conversation by the synthetic video of this method while conversing.
