Technical scheme in the embodiment of the present invention is for solving above-mentioned technical problem, and general thought is as follows:
Take pictures or when video image, determine the position of the sound source of sending audio signal on image according to audio signal, the zone that the position of this sound source is corresponding is defined as first area, then the view data in the zone outside first area is reduced, for example, when video conference, generally participant each side often only pays close attention to the spokesman, because the mankind to the concern meeting of sound source far above the concern to background, so utilize the scheme in the embodiment of the present application can be by auditory localization, then the background image data beyond the sound source zone is reduced, to adapt to the restriction of bandwidth, thus, do not need too complicated algorithm just can realize image compression, nor affect the main information of image, can assist on the contrary the participant, to the conference speech people, larger concern is arranged, some jamming pattern information have been reduced.
In order better to understand technique scheme, below in conjunction with Figure of description and concrete execution mode, technique scheme is described in detail.
One embodiment of the invention provides a kind of image processing method, is applied on an electronic equipment, and as shown in Figure 1, the method comprises:
Step 110: first, constantly obtain the first audio signal and comprise the first image with the corresponding sound source of the first audio signal;
Step 112: zone corresponding to position of determining sound source on the first image is first area, and the zone outside first area is second area;
Step 114: the view data that reduces second area.
Wherein, in step 110, constantly obtaining the first audio signal first, can be to obtain by an independent microphone, can be also to obtain by microphone array, microphone array can form directional wave beam, receive only speaker's sound, spokesman's sound, also can suppress noise and interference in environment, so the first audio signal of obtaining by microphone array can be clearer, and substantially there is no noise and interference.
Further, the first image can obtain by a camera, and this camera can be to be embedded in this electronic equipment, can be also for example, to be connected on this electronic equipment by a connecting interface (USB interface) is outer, in other embodiments, can be also to obtain by other image acquiring devices.
In step 112, zone corresponding to position of determining sound source on the first image is first area, zone outside first area is second area, in specific implementation process, at first carry out auditory localization, after auditory localization completes, then the position of sound source is labeled on image, on the first image by the location positioning of sound source out.Wherein, the method of auditory localization has a variety of, for example microphone array is located, even be equally, utilize microphone array to carry out auditory localization, different processing modes is wherein also arranged, for example the steerable beam based on peak power output forms technology, poor based on the time of advent, below just take microphone array and carries out auditory localization and describe as example based on differing from the time of advent.
Please refer to Fig. 2, electronic equipment comprises a display 10, display 10 has respectively 4 turnings, the first turning 101, the second turning 102, the 3rd turning 103 and the 4th turning 104, electronic equipment also comprises the microphone array that four microphones form, wherein the first microphone 201 is arranged at 101 places, the first turning, second microphone 202 is arranged at the second corner 102 places, the 3rd microphone 203 is arranged at 103 places, the 3rd turning, the 4th microphone 204 is arranged at 104 places, the 4th turning, the first microphone 201, second microphone 202, the setting position of the 3rd microphone 203 and the 4th microphone 204 forms a rectangle, the first microphone 201, second microphone 202, the 3rd microphone 203 and the 4th microphone 204 lay respectively on four summits of this rectangle.
The concrete grammar that carries out auditory localization comprises: the first microphone 201 is in first sub-time point t1 typing the first audio signal; Second microphone 202 is in second sub-time point t2 typing the first audio signal; The 3rd microphone 203 is in the 3rd sub-time point t3 typing the first audio signal; The 4th microphone 204 is in the 4th sub-time point t4 typing the first audio signal; Time difference based between the first sub-time point t1, the second sub-time point t2, the 3rd sub-time point t3 and the 4th sub-time point t4, determine the position of sound source.
The implementation of the method for above-mentioned auditory localization also has multiple, for example supposes that the coordinate of the first microphone 201, second microphone 202, the 3rd microphone 203 and the 4th microphone 204 is respectively S1(x1, y1, z1), S2(x2, y2, z2), S3(x3, y3, z3) and S4(x4, y4, z4), the coordinate of position in space of supposing sound source is T(x, y, z), and four microphones have same sampling time benchmark, also can Real-time Obtaining to local sound propagation velocity c.Then utilize the distance between two points formula to equal sound propagation velocity and be multiplied by sound and be sent to the principle of the time of microphone from the position of sound source, can calculate the time difference vector of corresponding sound source position, and then can be in the hope of the position T(x of sound source, y, z).
In another embodiment, can also be four microphone typing the first audio signals, and output time-domain signal according to this, then time-domain signal is converted to respectively to frequency-region signal, for example, via fast Fourier transform, time-domain signal is converted to frequency-region signal, further carry out the cross spectral calculation according to frequency-region signal again, the wavefront that can obtain sound source enters microphone 202 to the wavefront of microphone 204 and sound source and enters the time of advent poor (t2-t1) ~ (t4-t1) between microphone 201, and according to the time of advent poor (t2-t1) ~ (t4-t1), microphone 201 just can draw the position of sound source to position and the sound propagation velocity c of microphone 204.
In another embodiment, also can adopt 2 timers to realize, suppose that the first microphone 201 first receives the first audio signal, the first audio signal first arrives, and opens first timer and carry out timing in the end points that the first audio signal detected; Then the first audio signal arrives second microphone 202, at the end points that the first audio signal detected, just closes first timer and timing data T1 is stored, and then the zero clearing first timer is opened second timer simultaneously and carried out timing; When the first audio signal arrives the 3rd microphone 203, when the end points of the first audio signal being detected, close second timer and timing data T2 is stored equally, again open first timer and carry out timing simultaneously; When the first audio signal arrives the 4th microphone 204, same when the end points of the first audio signal being detected, close first timer and timing data T3 is stored.
So just can obtain 3 time data T1, T2 and T3, be T1 the first microphone 201 and the second Mike's 202 time of delay, be that T1 adds T2 the time of delay of the first microphone 201 and the 3rd microphone 203, be that T1 adds T2 and adds T3 the time of delay of the first microphone 201 and the 4th microphone 204, and be T2 the time of delay of second microphone 202 and the 3rd microphone 203; Be that T2 adds T3 the time of delay of second microphone 202 and the 4th microphone 204; The rest may be inferred by analogy for it, then in conjunction with sound propagation velocity c, just can calculate the delay distance between every two microphones, further can calculate the particular location of sound source.
Although above, be to classify example as with the microphone array of four microphones formations to describe, but in actual applications, as long as the array be comprised of two microphones just can be realized having located, so as long as the quantity of microphone is more than or equal to two, for example as shown in Figure 2, only utilize the first microphone 201 and the 4th microphone 201, or the first microphone 201 and the 3rd microphone 203, or the combination of the 3rd microphone 203 and the 4th microphone 204.In addition, microphone also need not necessarily be arranged on corner, as long as mutually, distance is not too near, during apart from each other, antijamming capability is stronger, and it is more that the number of microphone arranges, the acoustic information that may obtain is also more, and auditory localization also can be more accurate.
Mode in above each embodiment is auditory localization mode well known to those skilled in the art, at this, just repeats no more.Certainly, also also have other account form, those skilled in the art can adopt different locate modes according to actual conditions.
In addition, according to the principle of microphone array, each microphone is processed in the first audio signal of similar and different time point typing, for example mixed, just can be obtained first audio signal in first moment.
After the physical location of having determined sound source, will determine based on this physical location corresponding sound source position on the first image, further the location positioning first area based on sound source again.
Concrete determine corresponding sound source position based on physical location on the first image, can be for example to use three dimensional virtual technique out virtual the physical location of point source of sound by the relative position relation between microphone array and camera, utilize camera position information and angle lens information to make the Softcam visual angle, use virtual technology to take virtual sound source physical location out with virtual camera visual angle, draw the two dimensional image of this physical location on the camera photographic images, obtain the two-dimensional coordinate of this physical location on the camera photographic images, so just can determine the sound source position of this physical location correspondence on the first image.For example, in Fig. 2, camera head 30, be for example camera be located in the microphone array same plane on, and be positioned at the centre of second microphone 202 and the 3rd microphone 203, and the camera visual angle is perpendicular to this plane, so be easy in this case just can determine the sound source position on the first image.In other embodiments, camera head 30 also can be arranged on other positions, or external camera, as long as but can get the relative position relation between microphone array and camera head 30.
In other embodiments, also can by other means the physical location of sound source be corresponded in the first image, those skilled in the art can be selected according to actual needs.
After on the first image, determining sound source position, just on the first image, by sound source position, corresponding zone is defined as first area.In specific implementation process, because what locate out with microphone array may be a point, it may be also a band, especially when a some, because the spokesman is a people, so spokesman's head image should also will be done an effect of giving prominence to the key points, so in this case, just this first area is determined in the zone in a preset range around the position of sound source position, for example, centered by sound source position, the scope that one preset value is radius is interior as first area, this preset value is for example 1cm or 2cm, generally, in this radius, spokesman's main image information just can have been included.
Although the sound source of take in above-described embodiment describes as example, but in some cases, the people of speech may have two or more simultaneously, even spokesman's position every distant, but the processing to each sound source is identical, those skilled in the art can according to aforesaid be described clearly know multi-acoustical the time implementation method, so do not repeat them here.
More than describe the specific implementation process of step 112 in detail, next will introduce the specific implementation process of step 114.
When determined first area and second area in step 112 after, before the first image transmitting is gone out, in order to adapt to low network speed and the inadequate situation of bandwidth, the view data of second area be reduced, thus, neither affect the reception of beholder to interested information, and because volume of transmitted data is little, so transmission speed is very fast, so for example when video conference, whole process can be more smooth, and real-time is better.
In one embodiment, the view data that reduces second area can realize by a lot of methods, for example at first the image of first area is split, then second area is carried out to High frequency filter, use low pass filter elimination radio-frequency component, because the details of image is all radio-frequency component, profile is all low-frequency component, so very large image detail elimination these data volumes, will greatly reduce background image data, and then first area is stitched together with Image Mosaics technology and the second area of processing, then transfer out.Again for example, can directly with mask technique, mask be carried out in first area, then directly the first image be carried out to High frequency filter, because there is mask first area, so only can carry out High frequency filter to second area, after finishing dealing with, again the mask of first area be removed and gets final product.
As shown in Figure 3, the first image 40 is the image after processing, the important personage that the first spokesman 401 and the second spokesman 402 and their side are arranged in a row has kept former resolution (row in the middle of image), and background 403 is what to process, so decrease resolution is fuzzyyer, given prominence to spokesman and VIP's image information, and unessential background image data is reduced, adapted to the restriction of bandwidth and network speed.Specifically, in video conference, each two field picture all being done to such processing, is also this effect so whole video embodies.
In the prior art, the method that reduces the view data of second area also has a lot, and those skilled in the art know these methods, so just repeat no more at this.
A kind of electronic equipment also is provided in another embodiment of the present invention, has please refer to Fig. 4, this electronic equipment comprises: sound input device 501 obtains the first audio signal constantly first; Image acquiring device 502, obtain first the first image comprised with the corresponding sound source of the first audio signal constantly; The first process chip 503, determine that on the first image the zone corresponding to position of sound source is first area, and the zone outside first area is second area; The second process chip 504, the view data of minimizing second area.
Refer again to Fig. 2, electronic equipment also comprises a display 10, display 10 has respectively 4 turnings, the first turning 101, the second turning 102, the 3rd turning 103 and the 4th turning 104, sound input device 501 is microphone arrays that comprise that four microphones form, wherein the first microphone 201 is arranged at 101 places, the first turning, in first sub-time point typing the first audio signal; Second microphone 202 is arranged at the second corner 102 places, in second sub-time point typing the first audio signal; The 3rd microphone 203 is arranged at 103 places, the 3rd turning, in the 3rd time point typing the first audio signal; The 4th microphone 204 is arranged at 104 places, the 4th turning, in the 4th sub-time point typing the first audio signal; The setting position of the first microphone 201, second microphone 202, the 3rd microphone 203 and the 4th microphone 204 forms a rectangle, and the first microphone 201, second microphone 202, the 3rd microphone 203 and the 4th microphone 204 lay respectively on four summits of this rectangle.Then the time difference of the first process chip 503 based between the first sub-time point, the second sub-time point, the 3rd time point and the 4th sub-time point, determine the position of sound source, then this first area of the location positioning based on sound source.
Certainly, in another embodiment, as long as the array be comprised of two microphones just can be realized having located, so as long as the quantity of microphone is more than or equal to two, for example as shown in Figure 2, only utilize the first microphone 201 and the 4th microphone 201, or the first microphone 201 and the 3rd microphone 203, or the combination of the 3rd microphone 203 and the 4th microphone 204.In addition, microphone also need not necessarily be arranged on corner, as long as mutually, distance is not too near, during apart from each other, antijamming capability is stronger, and it is more that the number of microphone arranges, the acoustic information that may obtain is also more, and auditory localization also can be more accurate.
