Fig. 3 illustrates video communication method according to a first embodiment of the present invention, and Fig. 4 is illustrated according to the present invention first The video communication system of embodiment.

Video communication method according to a first embodiment of the present invention illustrated in Fig. 3 can apply to regarding illustrated in Fig. 4 Frequency communication system 300.As illustrated in figure 4, the video communication system 300 includes:Local terminal apparatus for video communication 100 and opposite end are regarded Frequency communication equipment 200.The local terminal apparatus for video communication 100 passes through various modes with the opposite end apparatus for video communication 200(Such as, Cable network and wireless network)And link together, and transmit according to the data format of agreement video communication data.

Here, mobile phone is entered as the example of local terminal apparatus for video communication 100 and opposite end apparatus for video communication 200 Row explanation.It may be evident, however, that the invention is not restricted to this.It the invention applies also to notebook, tablet personal computer, individual In video communication between the same types such as digital assistants or different type electronic equipment.

The local terminal apparatus for video communication 100 includes:Extraction element 110, the first code device 120, the and of dispensing device 130 Trap setting 140.

The opposite end apparatus for video communication 200 includes:Reception device 210, the first decoding apparatus 220 and display device 230.

As illustrated in fig. 3, video communication method according to a first embodiment of the present invention includes:

In step S210, video sequence is caught.

Specifically, when home is wanted with carrying out video calling in its long-range the other user, home can With using in its local local terminal apparatus for video communication 100(For example, the mobile phone of home), pass through such as third generation The cable network or wireless network of mobile communications network etc to initiate video calling request to the other user.

Now, in the local opposite end apparatus for video communication 200 of the other user(Similarly, such as mobile phone)To other side User's prompting home initiates video calling request to it.After the other user's selection receives call request, two Video calling connection is set up between person.

Below, to be set in the local terminal apparatus for video communication 100 at home end to other side's video communication at the other user end Exemplified by standby 200 transmission video image, video communication method according to a first embodiment of the present invention is gone on to say.It may be evident, however, that right Other side's apparatus for video communication 200 of square user terminal can equally be regarded to the transmission of local terminal apparatus for video communication 100 at home end Frequency image, the processing now performed in both will be exchanged.

For example, after video calling connection is set up, in local terminal apparatus for video communication 100, trap setting 140(For example, Camera on mobile phone)The video sequence of home is caught, the video sequence is made up of a series of picture frame.

Now, itself resolution ratio is set to first resolution by trap setting 140.Preferably, the first resolution is this The ultimate resolution that trap setting 140 can be supported.So, trap setting 140 is regarded using maximum resolution ratio to catch a frame Frequency image, to obtain the video image of a secondary fine definition as far as possible, then the video image captured is sent to by it Extraction element 110, to carry out subsequent treatment.

In step S220, characteristic area is extracted from image.

Specifically, after the video image that trap setting 140 is caught is received, extraction element 110 is for the video Image performs characteristic area detection algorithm, to obtain position of the characteristic area in raw video image.

Here it is considered that, it is however generally that, the both sides for carrying out video communication are relatively concerned with the facial information of user, therefore, Preferably, this feature region can be chosen for the human face region of user, and this feature Region detection algorithms can be face Detection and/or Face tracking algorithm.It may be evident, however, that the invention is not restricted to this.By such as home limbs or it can also be in Other regions of the local display of home etc are chosen for the characteristic area of the other user's care.

Face datection algorithm be used for detect whether there is face in the input image, and determine all faces position, Size, pose.Face datection is a key technology in face information processing., can be with according to the color attribute using feature Face datection algorithm is divided into the method based on features of skin colors and the class of the method based on gray feature two.

Face tracking algorithm be generally used on the basis of Face datection for human face in video frequency sequence movement position with Track.Face tracking algorithm includes based drive method and the method based on model.

It should be noted that extraction element 110 can be using any face inspection that is existing or developing in the future Survey and/or Face tracking algorithm, to detect human face region in the raw video image that trap setting 140 is captured, it is determined that The position of the human face region, and extract from each two field picture the human face region.

Now, it is preferable that while human face region is extracted from each two field picture, the extraction element 110 is also further Monitor the central processing unit in local terminal apparatus for video communication 100(CPU)Performing Face datection and/or Face tracking algorithm when institute The resource of occupancy, and judge whether the shared system resource of detection operation is more than or equal to a predetermined resource threshold Value, for example, 50%.

For example, when the extraction element 110 is the first of the video sequence caught to trap setting 140 using ultimate resolution When two field picture is detected, if the shared system resource of detection operation is beyond the 50% of the overall resources of CPU, the extraction Device 110 thinks that now Face datection and/or Face tracking algorithm occupancy CPU resource are excessive, may influence to regard in local terminal The other application run in frequency communication equipment 100.Therefore, the extraction element 110 sends resolution changing letter to trap setting 140 Number.The trap setting changes into the first resolution as ultimate resolution slightly according to the resolution changing signal Smaller second resolution, in subsequent operation, to catch the second frame of the video sequence using second resolution Image.In this manner it is achieved that the extraction element 110 can gradually be turned down with frame by frame trap setting 140 catch video sequence when Resolution ratio, untill the detection operates shared system resource to be less than predetermined resource threshold.

Similarly, when user due to having exited the other application run in local terminal apparatus for video communication 100 causes the inspection When surveying less system resource shared by operation, the extraction element 110 can also gradually heighten trap setting 140 and catch video sequence Resolution ratio during row so that obtain the user's face image become apparent from, untill the resolution ratio is equal to ultimate resolution.

By above-mentioned processing, realized with traditional visual telephone and typically be directly disposed as the resolution ratio of camera to show Size compare, the first embodiment of the present invention can adjust the resolution ratio of camera according to system resource, so as to obtain one Width clearly original facial image as far as possible.

Furthermore it is preferred that after human face region is detected from original video sequence, the extraction element 110 can be with The size of detected human face region is compared with a default dimension threshold, wherein the dimension threshold depends on regarding The bandwidth of frequency channel.If the size of detected human face region is less than the dimension threshold, to detected face Region is amplified processing so that the size of detected human face region is equal to the dimension threshold.This scene generally occurs Home portrait apart from camera farther out in the case of.Similarly, if the size of detected human face region is more than The dimension threshold, then carry out diminution processing so that the size of detected human face region to detected human face region Equal to the dimension threshold.This scene occurs in the portrait situation nearer apart from camera.

Pass through above-mentioned processing, compared with the conventional video phone operated without Face datection is realized, of the invention first Embodiment can overcome the facial image being likely to occur to show excessive or too small feelings in opposite end apparatus for video communication 200 Condition.

Because camera is set to ultimate resolution by trap setting 140 in step S210, so in step S220, The facial image that the extraction element 110 of extraction element 110 can be obtained according to the size of display Video coding to detection is fitted When scaling so that during face video stream after subsequently to scaling is encoded, ensure encoder bit rate expire While sufficient visual telephone transmission code rate requirement, it is ensured that a definition highest is obtained in the range of camera blur-free imaging Facial image.

Finally, the human face region extracted is sent to the first code device 120 by the extraction element 110, after progress Continuous processing.

In step S230, characteristic area is encoded using the first coding method.

Specifically, after the human face region that extraction element 110 is extracted is received, the first code device 120 is used First coding method is encoded to the human face region, to generate the video flowing to be transmitted.

For example, first code device 120 can use various method for video coding(Such as, Motion Picture Experts Group (MPEG)4、H.263、H.264)To be encoded to the human face region extracted.Because the video image to be encoded only is included Human face region and human face region varying less in whole video call process, so between the frame and frame of video flowing Difference can very little, accordingly even when rock it is very big in the case of it is also ensured that the encoder bit rate of very little.

Then, the video image after coding is sent to dispensing device 130 by first code device 120, for follow-up Processing.

In step S240, the characteristic area after coding is sent to receiving terminal.

Specifically, after the human face region after receiving coding, dispensing device 130 is for example, by 3G (Third Generation) Moblie Network is sent to opposite end apparatus for video communication 200 only includes the video flowing of human face region.

In step s 250, receive and decode the characteristic area after the coding.

Specifically, in opposite end apparatus for video communication 200, reception device 210 is received via such as mobile communications network Only include the video flowing of human face region, and be transferred to the first decoding apparatus 220.

First decoding apparatus 220 can use the first coding/decoding method corresponding with the first coding method to come to the video flowing Decoded, therefrom to recover the image for including human face region.

In step S260, characteristic area is shown.

Specifically, after the human face region after coded by being received from first decoding apparatus 220, display device 230 The display device equipped in opposite end apparatus for video communication 200(Such as, display screen)The facial image of upper display fixed size, and And the facial image is far longer than the general display size 176 × 144 realized in traditional video communication.It is demonstrated experimentally that root Being realized according to the video communication of first embodiment of the invention can reach that the display of 176 × 144 × 2, the even more big order of magnitude is big It is small.

Further, since the code check very little produced in local terminal apparatus for video communication 100 in the Video coding of facial image, So can suitably expand the display of video image in opposite end apparatus for video communication 200.This operation can be according to reality The code check of generation is adjusted.Therefore, a kind of video of high-definition portrait pattern is realized in video communication system 300 to lead to Letter.

As can be seen here, using video communication method according to a first embodiment of the present invention and system, it is possible to use face is examined Survey technology extracts facial image in the video image of each frame, and appropriate scaling, coding are then only carried out to facial image, this Sample can greatly improve the definition of facial image.Specifically, even in image rock it is larger in the case of, due to only passing Difference between defeated facial image, every frame of image is smaller, so the code check produced after coding also can be reduced greatly, so as to To considerably improve the definition of facial image, size and continuity in visual telephone, high-definition portrait pattern is realized Video communication.

Therefore, in the first embodiment of the present invention, the high-definition portrait pattern of this video communication can be regard as one kind Additional option is provided in the user interface of electronic equipment so that user can not only be regarded by traditional general mode Frequency communicate, to transmit the video data for including the various image informations such as face and background between users, thus recognize with The related comprehensive information of user;But also video communication can be carried out by high-definition portrait pattern, so that the other user can be with Facial expression of home etc. is more clearly observed, so as to realize preferably talk experience.
