Embodiment

Referring to Fig. 1, be the information transferring method in the embodiment of the present invention, described method can be applied to the first electronic equipment.The main flow process of described method is as follows:

Step 101: when need transmit the first frame image information, according to default priority, described the first frame image information and at least one frame image information of transmission are before compared respectively, generate a comparison result.

When needs transmit described the first frame image information, can described the first frame image information and at least one frame image information of transmission before be compared respectively according to default priority.

In the embodiment of the present invention, can be according to default priority, described the first frame image information and the front M frame image information of transmission before to be compared, M be positive integer; Or, can be according to default priority, described the first frame image information and the front L frame image information of transmission before to be compared respectively.

In the embodiment of the present invention, the priority according to default by described the first frame image information with before transmission at least one frame image information compare before, the region that can also first according to significance level, one frame image information be comprised is divided at least two priority, in the region successively described the first frame image information being comprised according to priority order from high to low more afterwards and the described at least one frame image information sending before for region compare respectively.

The region that preferably, can one frame image information be comprised according to significance level in the embodiment of the present invention is divided into four priority.Because in the image transmitting in the application processes such as video calling, what relatively pay close attention to is the situation of change of people in video, and therefore, in a frame image information, people's priority will be higher than the priority of background environment.Again, in human body, people's facial expression is again even more important focus, therefore, in the embodiment of the present invention, people's face can be preset as to the first priority, people's face can be preset as to the second priority in the region except face, people's limbs can be preset as to the 3rd priority, background environment can be preset as to the 4th priority.The severity level of wherein said the first priority is the highest, and the severity level of described the 4th priority is minimum.

In the embodiment of the present invention, the step of described the first frame image information and at least one two field picture of transmission before being compared respectively according to default priority can be specifically following two kinds of possible situations.Or this step also can have other execution mode, and the present invention does not limit:

One, the respective image information comprising in described the first image information comprising in the first corresponding first area of priority in described the first frame image information and described at least one frame image information is compared respectively, judge that whether the two is consistent; When judgement determines that the two is consistent, continue the respective image information comprising in described the first image information comprising in the corresponding second area of the second priority in described the first frame image information and described at least one frame image information to compare respectively; When judgement determines that the two is inconsistent, generate described comparison result.

That is: first the respective image information comprising in described the first image information comprising in the first corresponding first area of priority described in described the first frame image information and described at least one frame image information is compared respectively, judge that whether the two is consistent, if judgement determines that the two is consistent, can continue the respective image information comprising in described the first image information comprising in the corresponding second area of the second priority in described the first frame image information and described at least one frame image information to compare respectively, if judgement determines that the two is consistent, can continue the respective image information comprising in described the first image information comprising in corresponding the 3rd region of the 3rd priority in described the first frame image information and described at least one frame image information to compare, comparison so successively, until judgement determines that comparison result is inconsistent under a certain priority, can generate described comparison result, described comparison result can be inconsistent for being illustrated in the respective image information comprising in described the first image information of comprising in described the first frame image information under a certain priority and described at least one frame image information.Or, if after all priority is all compared, judgement determines that described the first image information comprising in described the first frame image information under each priority is all consistent with the respective image information comprising in described at least one frame image information, also can generate described comparison result, described comparison result can be all consistent with the respective image information comprising in described at least one frame image information for being illustrated in described the first image information comprising in described the first frame image information under each priority.

Two, the respective image information comprising in described the first image information comprising in corresponding each region of each priority in described the first frame image information and described at least one frame image information can be compared respectively, generate described comparison result., can first the respective image information comprising in described the first image information comprising in the first corresponding first area of priority described in described the first frame image information and described at least one frame image information be compared respectively, judge that whether the two is consistent, can record judged result, no matter judgement determines that whether the two is consistent, can continue the respective image information comprising in described the first image information comprising in the corresponding second area of the second priority in described the first frame image information and described at least one frame image information to compare respectively, judge that whether the two is consistent, can record judged result, no matter judgement determines that whether the two is consistent, can continue the respective image information comprising in described the first image information comprising in corresponding the 3rd region of the 3rd priority in described the first frame image information and described at least one frame image information to compare, judge that whether the two is consistent, can record judged result, no matter judgement determines that whether the two is consistent, can continue the respective image information comprising in described the first image information comprising in corresponding the 4th region of the 4th priority in described the first frame image information and described at least one frame image information to compare, so successively after comparison, can generate described comparison result, whether described comparison result can be consistent with the respective image information comprising in described at least one frame image information for being illustrated in described the first image information comprising in described the first frame image information under each priority.

One if compare described the first frame image information and the front M frame image information of transmission before according to default priority, and situation can be as described before.Wherein, can be from

Two if compare described the first frame image information and the front L frame image information of transmission before respectively according to default priority, and situation can be as follows:

For example L=3, supposes described the first frame image information and front the second frame image information, front the 4th frame image information and front the 5th frame image information of transmission before to compare respectively.

For example, when described the first frame image information and described front the second frame image information are compared, the comparison mode adopting can be that as above the first is compared mode, that is: first the respective image information comprising in described the first image information comprising in the first corresponding first area of priority described in described the first frame image information and described front the second frame image information is compared, judge that whether the two is consistent, if judgement determines that the two is consistent, can continue the respective image information comprising in described the first image information comprising in the corresponding second area of the second priority in described the first frame image information and described front the second frame image information to compare, if judgement determines that the two is consistent, can continue the respective image information comprising in described the first image information comprising in corresponding the 3rd region of the 3rd priority in described the first frame image information and described front the second frame image information to compare, comparison so successively, until judgement determines that comparison result is inconsistent under a certain priority, can generate described comparison result, described comparison result can be inconsistent for being illustrated in the respective image information comprising in described the first image information of comprising in described the first frame image information under a certain priority and described front the second frame image information.Or, if after all priority is all compared, judgement determines that described the first image information comprising in described the first frame image information under each priority is all consistent with the respective image information comprising in described front the second frame image information, also can generate described comparison result, described comparison result can be all consistent with the respective image information comprising in described front the second frame image information for being illustrated in described the first image information comprising in described the first frame image information under each priority.

In the present embodiment, at the comparison result that described the first frame image information and described front the second frame image information are compared, can be that in described the first frame image information, change has occurred described first image information of the corresponding second area of the second priority.

In the present embodiment when described the first frame image information and described front the second frame image information are compared, the comparison mode adopting can be also as above the first comparison mode, in the present embodiment, at the comparison result that described the first frame image information and described front the 4th frame image information are compared, can be that in described the first frame image information, change has occurred described first image information of the first corresponding first area of priority.

In the present embodiment when described the first frame image information and described front the 5th frame image information are compared, the comparison mode adopting can be that as above the second is compared mode, that is: the respective image information comprising in described the first image information comprising in corresponding each region of each priority in described the first frame image information and described front the 5th frame image information can be compared respectively, generate described comparison result., can first the respective image information comprising in described the first image information comprising in the first corresponding first area of priority described in described the first frame image information and described front the 5th frame image information be compared, judge that whether the two is consistent, can record judged result, no matter judgement determines that whether the two is consistent, can continue the respective image information comprising in described the first image information comprising in the corresponding second area of the second priority in described the first frame image information and described front the 5th frame image information to compare, judge that whether the two is consistent, can record judged result, no matter judgement determines that whether the two is consistent, can continue the respective image information comprising in described the first image information comprising in corresponding the 3rd region of the 3rd priority in described the first frame image information and described front the 5th frame image information to compare, judge that whether the two is consistent, can record judged result, no matter judgement determines that whether the two is consistent, can continue the respective image information comprising in described the first image information comprising in corresponding the 4th region of the 4th priority in described the first frame image information and described front the 5th frame image information to compare, so successively after comparison, can generate described comparison result, whether described comparison result can be consistent with the respective image information comprising in described front the 5th frame image information for being illustrated in described the first image information comprising in described the first frame image information under each priority.

In the present embodiment the comparison result that described the first frame image information and described front the 5th frame image information are compared can be in described first image information in corresponding the 3rd region of the 3rd priority in described the first frame image information and described the first frame image information described in the corresponding four-range of the 4th priority the first image information all there is change, in described the first frame image information, in described first image information of the first corresponding first area of priority and described the first frame image information, described first image information of the corresponding second area of the second priority does not change.

In the present embodiment, when described the first frame image information and described front the second frame image information, described front the 4th frame image information and described front the 5th frame image information are compared respectively, the comparison result obtaining is all not identical, can, according to comparison result, according to priority, select to need the content of transmission.

For example, in the present embodiment, comparison result shows in described the first frame image information that change has all occurred the content in the region that four priority is corresponding, when transmission, can only transmit corresponding described the first image information of the first priority described in described the first frame image information, or when transmission, also can transmit corresponding described the first image information of the second priority described in corresponding described the first image information of the first priority described in described the first frame image information and described the first frame image information, or when transmission, also can transmit corresponding described the first image information of the first priority described in described the first frame image information, corresponding described the first image information of the 3rd priority described in corresponding described the first image information of the second priority and described the first frame image information described in described the first frame image information, or also can be by corresponding described the first image information of the first priority described in described the first frame image information when transmission, corresponding described the first image information of the second priority described in described the first frame image information, corresponding described the first image information of the 4th priority described in corresponding described the first image information of the 3rd priority and described the first frame image information described in described the first frame image information is all transmitted.Concrete transmission situation can be set as required.

Or, if the comparison result obtaining when described the first frame image information and described front the second frame image information are compared is: variation has occurred described the first image information described in described the first frame image information in the first corresponding described first area of priority, the comparison result obtaining when described the first frame image information and described front the 4th frame image information are compared is: variation has occurred described the first image information in the corresponding described second area of the second priority described in described the first frame image information, the comparison result obtaining when described the first frame image information and described front the 4th frame image information are compared is: variation has occurred described the first image information in the corresponding described second area of the second priority described in described the first frame image information.According to general selective rules, because all show that in two comparison results variation has occurred corresponding described the first image information of the second priority described in described the first frame image information, can only transmit described the first image information in the corresponding described second area of the second priority described in the first frame image information, but there is a comparison result also to show that described in described the first frame image information, variation has also occurred described the first image information in the first corresponding described first area of priority, and described the first priority corresponding be people's face, it is the content of paying close attention to the most in video calling, therefore in order to obtain better video speech quality, when transmission, also described the first image information in the corresponding described second area of the second priority described in described the first image information in the first corresponding described first area of priority described in described the first frame image information and described the first frame image information can be transmitted in the lump.For example, in this case, if there are two comparison results to show that variation has occurred described the first image information in the corresponding described second area of the second priority described in described the first frame image information, there is a comparison result to show that described in described the first frame image information, variation has occurred described the first image information in the 3rd corresponding described the 3rd region of priority, when transmission, can only transmit described the first image information in the corresponding described second area of described the second priority.

In the embodiment of the present invention, before carry out step 101, can also first control described the first electronic equipment and enter first mode.In the embodiment of the present invention, described first mode can refer to energy saver mode, can be specifically the mode of operation that network quality is used when not so good.

In the embodiment of the present invention, can be first according to current network mass value judgement current network quality, if judged result shows described current network mass value and is less than default network quality threshold value, can determine that current network quality is not so good, can control described the first electronic equipment and enter described first mode.Step shown in Fig. 1 is all that described the first electronic equipment completes under described first mode.

Step 102: when described comparison result shows that the respective image information comprising in the first image information of comprising in described the first frame image information and described at least one frame image information is inconsistent, generate the first transfer instruction.

In the embodiment of the present invention, described the first transfer instruction can be for representing described the first image information of transmission, and described the first image information can be corresponding to a priority, or described the first image information also can be corresponding to a plurality of priority.

In the embodiment of the present invention, can only transmit the part changing in a two field picture, if people keeps motionless in video call process always, comparison result can be the region not changing in described the first frame image information, can not transmit, if or people has left in video call process, in described the first frame image information, may only include the environment of having powerful connections, the background environment that described the first frame image information comprises may not change yet, can not transmit, although or there is variation in the background environment in described the first frame image information, but because background environment belongs to described the 4th region corresponding to priority of stipulating in the embodiment of the present invention, can not transmit yet, so can save flow.

In the embodiment of the present invention, when the percent value that the pixel changing accounts for all pixels that this region comprises is not less than default percent value, can determine the image information inconsequent that this region is included in a region.

For example, when the corresponding respective regions of the first priority described in described first area corresponding to the first priority described in described the first frame image information and front the first frame image information is compared, if the pixel changing in described first area corresponding to the first priority described in described the first frame image information accounts for the percent value of all pixels that this region comprises and is not less than default percent value, can determine described the first image information inconsequent that described first area corresponding to the first priority described in described the first frame image information is included, can determine that variation has occurred included described the first image information in described first area corresponding to the first priority described in described the first frame image information.

Step 103: carry out described the first transfer instruction, to first image transmission to the second electronic equipment described in major general.

Carry out described the first transfer instruction, can be to the first image transmission described in major general to described the second electronic equipment.In the embodiment of the present invention, described the first image information can be the image information changing corresponding to a priority, or described the first image information can be the region changing corresponding to a plurality of priority.

The image information that in the embodiment of the present invention, only transmission changes, or also the image information not changing also can be transmitted, to improve the integrality of transferring content.

In the embodiment of the present invention, when described the first image information of transmission, after described the first image information can being compressed according to certain compression ratio, transfer to described the second electronic equipment.

Wherein, in the embodiment of the present invention, each priority can corresponding same compression ratio, and for example each priority can be corresponding to the first compression ratio, or, can set in advance different compression ratios for each priority, for example, described the first priority can corresponding the second compression ratio, and described the second priority can corresponding the 3rd compression ratio, described the 3rd priority can corresponding the 4th compression ratio, and described the 4th priority can corresponding the 5th compression ratio.Wherein because compression ratio more may distortion situation more serious, each priority sets in advance different compression ratios if, priority is higher, the compression ratio of setting can be less.

When described the first image information of transmission, after described the first image information can being compressed according to the compression ratio corresponding with it, transmit.

One, described the first image information is only corresponding to a priority.

If each priority transfers to described the second electronic equipment after all corresponding to described the first compression ratio, described the first image information can being compressed according to described the first compression ratio.

Each priority has set in advance different compression ratios if, after can described the first image information being compressed according to the compression ratio corresponding with described the first image information, transfers to described the second electronic equipment.For example, described the first image information, corresponding to described the second priority, transfers to described the second electronic equipment after described the first image information can being compressed according to described the second compression ratio.

Two, described the first image information is corresponding to different priority.

Each priority has set in advance different compression ratios if, can according to each priority respectively corresponding compression ratio after described the first image information is compressed respectively, transfer to described the second electronic equipment.For example the first subimage information in described the first image information is corresponding to described the second priority, the second subimage information in described the first image information is corresponding to described the 3rd priority, can described the first subimage information be compressed according to described the second compression ratio, according to described the 3rd compression ratio, described the second subimage information is compressed, and described the second subimage communication by described the first subimage information after compression and after compressing is to described the second electronic equipment.

By several specific embodiments, introduce the information transferring method in the present invention below, following embodiment has introduced several possible application scenarios of described information transferring method.It should be noted that, the embodiment in the present invention is only for explaining the present invention, and can not be for limiting the present invention.Every embodiment that meets inventive concept is all within protection scope of the present invention, and those skilled in the art know how thought according to the present invention is out of shape naturally.
