In the present embodiment, in the presetting bit record each has comprised recorded information and presetting bit information, recorded information has write down the situation in meeting-place, comprise that numbering is (when only preserving the presetting bit in local meeting-place, then do not number this), record name, meeting place name, meeting-place number, picture etc., specifically explanation in the aforementioned embodiment; Presetting bit information has then comprised positional information and image, positional information is used to identify the position of each different camera lenses, as rostrum, spokesman, spectators 1, spectators 2, the whole audience etc., image is the image of corresponding each lens location, can directly extract from this camera lens.
When presetting bit when record that finds coupling, then can directly use the presetting bit of this presetting bit in writing down by presetting bit applying unit 42, camera lens is adjusted to the position of needs.In the present embodiment, if found the presetting bit record of coupling, but the presetting bit in this presetting bit record all be unsatisfied with, also can be undertaken up and down and operation such as convergent-divergent focusing, regulate the position of camera lens to needs by the described video camera of camera lens control unit 43 controls.If the presetting bit recorded and stored on control ground, this locality, can also be preserved this presetting bit information in this presetting bit entry then further by presetting bit edit cell 44 these presetting bit records of editor; Perhaps by presetting bit edit cell 44 these presetting bit records of deletion.If presetting bit record is not to be kept at this locality, but when being kept at remote site, then can not edit or operation such as deletion it.
When presetting bit when record that does not find coupling, then can be undertaken up and down and operation such as convergent-divergent focusing by the described video camera of camera lens control unit 43 controls, regulate camera lens to the position that needs.If the presetting bit recorded and stored on control ground, this locality, can also comprise recorded information and presetting bit information further by presetting bit edit cell 44 editor's presetting bit records, preserving this recorded information and presetting bit information then is a new presetting bit entry.If presetting bit record is not to be kept at this locality, but when being kept at remote site, then can not edit the operation of preservation to it.
Camera lens control set for adjusting by present embodiment, solved and to have carried out the defective that presetting bit is preserved at different remote sites specially, make the terminal use with different remote subscriber communication process in, needn't reset presetting bit, and directly search the presetting bit record by the recorded information in the presetting bit record, guarantee to navigate to the presetting bit data of Be Controlled meeting-place video camera fast, and feed back to the user, make the user can use existing presetting bit information easily.In addition, the matching process of searching of presetting bit realizes automatically in that product is inner, and is transparent to the user, thereby further increased the ease for use of function.
Be convenient to more understand for the video camera lens regulation control method and the device that make the embodiment of the invention, be described in further detail below by the method and apparatus of the operating instruction in several concrete application processes to the embodiment of the invention.In this several application was given an example, local meeting-place was a relative notion with remote site, referred to both sides' terminal of communication dialogue, described with the operating main body of local meeting-place as video camera control below.
Use one: local meeting-place saves presets the position, local meeting-place control video camera.
In should using, local meeting-place still is that the presetting bit record of video camera of remote site all is provided with and is preserved by local meeting-place, and the presetting bit of preserving record also can only be extracted and be used by local meeting-place.
In should using, under idle (non-conversation), point-to-point conversation, multiple spot talking state, when the video camera control of local meeting-place or remote site need be carried out in local meeting-place, enter the control interface, its handling process is as shown in Figure 5.
At first enter the control interface of video camera, automatically seek the presetting bit record of coupling then, if find the entry of coupling, then show recorded information and presetting bit information that should entry, edit if desired, then edit and preserve the back and use this presetting bit, if do not need editor, then directly use this presetting bit,, then on the control interface, show the space record interface of an acquiescence if do not find the entry of coupling, if newly-built record, then newly-increased entry is filled in recorded information and presetting bit information, and regulates camera lens to the position that needs, preserve relevant information, to use this presetting bit, if not newly-built record, the camera lens of then directly regulating video camera is to the position that needs.
In should using, the independent corresponding presetting bit entry in each meeting-place.Entry can comprise recorded information and presetting bit information, recorded information can comprise record number, record name, meeting place name, meeting-place number and picture etc., wherein, record number is generated by automatic by system, number unique, record name can be named by user oneself, then be sky when not naming, these two parameters of meeting place name and meeting-place number all can directly get access to, local meeting-place ten-four, remote site information then can get access to from conversation, the meeting field picture, directly extract current this locality meeting field picture or remote site image, be compressed to the size that needs then.In addition, each entry can be preserved a plurality of presetting bits, as 6, each presetting bit information can comprise positional information and picture, wherein positional information can be the presetting bit title, as rostrum, spokesman, spectators 1, spectators 2, meeting-place panorama etc., picture then directly extract current camera lens right image.
In should using, presetting bit record directly is kept in the non-memory cell of easily losing in local meeting-place, and what of stored record number are influenced by the size of memory cell directly.When reaching the maximum number of presetting bit record support, can select to cover existing record.Overlay strategy can have multiple: by the mode of first in first out, override the record of preserving the earliest; By frequency of utilization statistics, override at most obsolete record etc.
In should using,, therefore all be in local stored record, to carry out presetting bit information searching coupling because the presetting bit record all is kept at this locality.If when controlling local meeting-place video camera, directly pass through local meeting place name, meeting-place number as keyword, automatically in the presetting bit record that preserve this locality, search coupling, as find corresponding record, then directly recorded information is presented on the operation interface.If during control remote site video camera, in conversation, local meeting-place can directly extract remote site title, meeting-place number from call-information, then with these two parameters as keyword, automatically in the presetting bit record that preserve this locality, search coupling, as find corresponding record, then directly recorded information is presented on the operation interface.
In should using, presetting bit operation and video camera control operation can be unified in the interface and carry out, be more convenient for using.If do not find matched record, when promptly not having the video camera presetting bit information in current corresponding meeting-place in the record of Bao Cuning, the blank presetting bit operation interface that directly shows acquiescence, except that record number generates unique numerical value by system automatically, other information are sky, can directly carry out the focusing operation of convergent-divergent up and down of video camera on this interface, also directly every information of reference record, presetting bit information etc. are preserved then and are formed a new presetting bit record.Its operation interface as shown in Figure 6.If find matched record, when the video camera presetting bit information in current corresponding meeting-place is promptly arranged in the record of Bao Cuning, directly demonstrate corresponding presetting bit recorded information, on this interface, can directly use presetting bit, also can directly carry out the focusing operation of convergent-divergent up and down of video camera, also can directly edit and preserve every information, presetting bit information of corresponding record etc., also can select to dispose relative recording, discharge corresponding memory space.When wherein removing presetting bit information, record space can not discharge; When removing record, comprise that various presetting bit information all can dispose simultaneously, the memory space of this record just can discharge.Operation interface as shown in Figure 7.
In should using, no matter in no talking state,, can check local whole presetting bit information still in talking state, to edit, operation such as deletion, its operation interface is approximately as shown in Figure 8.When searching record, can search for by one or more information such as numbering, record name, meeting place name, meeting-place numbers.Every record can be clicked and enter, and the full detail of this record and presetting bit can be seen as shown in Figure 7 in its interface, operation such as also can edit.For the information of record name, meeting place name, meeting-place number, presetting bit title, under conversation or idle condition, all allow editor.Under special scenes, just allow to carry out for action needs such as video camera control operation, the renewal of meeting field picture, the renewals of presetting bit picture, for example, if the presetting bit record in local meeting-place all allows editor under conversation or idle condition; If the presetting bit record of remote site, then must talking state, and the conversation object just allows to carry out when just in time being the corresponding remote site of record, can directly carry out the picture renewal of correspondence by extracting current meeting-place, this locality (or far-end) real time picture.
In should using, situation for the multiple spot conversation, corresponding remote site has a plurality of, the video camera control of remote site is carried out in local meeting-place if desired, then obtain meeting place name, the meeting-place number information of the current remote site that will control automatically, carry out the coupling of searching of presetting bit record again, follow-up processing flow is identical with top described processing.
In should using, consider that the individual meeting site may dispose a plurality of video cameras, so video camera control and presetting bit the interface is set can be as shown in Figure 9.Each video camera all has own sequence number (as 1～4), and the title of video camera (can be named by the user), and each video camera all has oneself independently several presetting bit positional information.Herein, video camera sequence number and video camera name information also needs to preserve as the information of presetting bit record.When using presetting bit,,, then can finish the switching of video camera and the function of camera lens location simultaneously according to video camera information that writes down in the presetting bit and positional information if between the presetting bit of different cameras, switch.
According to should using, no matter idle no talking state, or talking state can be carried out the position setting of local video camera, and is kept at the local terminal as local presetting bit.And in point-to-point or multiple spot talking state, can the Remote Camera position be provided with, and be kept at the local terminal as the presetting bit in this meeting-place.The information of presetting bit record can comprise critical datas such as meeting place name, meeting-place number, presetting bit title, image.In free time or the talking state, when terminal was controlled local video camera, the automatic matched and searched of internal system was to the local presetting bit record of local correspondence of having preserved.Mainly can compare during coupling by meeting place name, meeting-place number.This presetting bit record can directly be used, and also can carry out edit-modify.In addition, also can not use presetting bit, directly carry out video camera convergent-divergent focus control up and down.In the point-to-point or multiple spot talking state, during terminal control remote site video camera, the far-end presetting bit record of the correspondence that the automatic matched and searched of internal system has been preserved to this locality.Mainly can compare during coupling by meeting place name, meeting-place number.This presetting bit record can directly be used, and also can carry out edit-modify.In addition, also can not use presetting bit, directly carry out video camera convergent-divergent focus control up and down.Under the various situations,, then can only directly carry out video camera convergent-divergent focus control up and down if do not find the presetting bit record.Whether can carry out the setting and the preservation of presetting bit record this moment, then the setting when finding presetting bit and to preserve operational constraints consistent.Processing procedure and technical scheme are above being described in detail, no longer describe in detail here.
Use two: remote site saves presets the position, local meeting-place control video camera.
In should using, the video camera presetting bit information in each meeting-place all oneself is provided with and is preserved by this meeting-place.When the remote site video camera need be controlled in local meeting-place in conversation, need to obtain its video camera presetting bit record from remote site earlier, and then carry out the application of presetting bit, can limit local meeting-place change far-end presetting bit record simultaneously.
In should using, under idle (non-conversation), point-to-point conversation, multiple spot talking state, when the video camera control of local meeting-place or remote site need be carried out in local meeting-place, enter video camera control interface, its handling process is as shown in figure 10.
At first enter the control interface of video camera, when the video camera in the local meeting-place of control, automatically seek the presetting bit record of coupling, if find the entry of coupling, then show recorded information and presetting bit information that should entry, edit if desired, then edit and preserve the back and use this presetting bit,, then directly use this presetting bit if do not need editor, if do not find the entry of coupling, the space record interface that then on the control interface, shows an acquiescence, if newly-built record, then newly-increased entry, fill in recorded information and presetting bit information, and regulate camera lens to the position that needs, preserve relevant information, to use this presetting bit, if not newly-built record, the camera lens of then directly regulating video camera is to the position that needs.When the video camera of control remote site, send the presetting bit solicited message to remote site, request presetting bit record, if find the entry of coupling, then show recorded information and presetting bit information that should entry, directly use this presetting bit, if do not find the entry of coupling, then on the control interface, show the space record interface of an acquiescence, control the operation that video camera carries out convergent-divergent focusing up and down then, with the lens location of control video camera.
In should using, each meeting-place only keeps the presetting bit information of this meeting-place video camera, i.e. presetting bit record has only one.Every content of presetting bit record is similar with application one, but owing to have only a record, therefore can reduce this item number certificate of record number.Remaining record name, meeting place name, the meeting-place number, data processing such as meeting field picture are identical with application one.
In should using, the presetting bit record directly is kept in the non-memory cell of easily losing in local meeting-place.Owing to only keep local record, therefore do not relate to number what and the record overlay strategy of keeping records.
In should using,, therefore,, then extract presetting bit information and be presented on the operation interface from this locality if control local meeting-place video camera because the video camera presetting bit record in local meeting-place is only preserved in each meeting-place; If control remote site video camera, then need from call-information, to extract earlier the remote site information that will control, comprise that meeting place name, meeting-place number are as keyword, send the presetting bit request message that comprises above-mentioned keyword for then corresponding meeting-place, after remote site is received request message, its presetting bit record is sent to local meeting-place by message; If there is not presetting bit information, then returns presetting bit and be empty information.
In should using, under the situation of the local meeting-place of control video camera, when if local presetting bit is recorded as sky, the blank presetting bit operation interface that directly shows acquiescence, on this interface, can directly carry out the focusing operation of convergent-divergent up and down of video camera, every information, presetting bit information of local presetting bit record etc. also can directly be set, preserve then, form new local presetting bit record.When if non-NULL is write down in local presetting bit, directly show the every information of local presetting bit, on this interface, can directly use presetting bit, also can directly carry out the focusing operation of convergent-divergent up and down of video camera, also can directly edit and every information of keeping records, presetting bit information etc., also can select to dispose record, make it revert to the blank presetting bit record of acquiescence.
In should using, under the situation of control remote site video camera, when if the presetting bit of remote site feedback is recorded as sky, the blank presetting bit operation interface that directly shows acquiescence, on this interface, can only directly carry out video camera up and down with the convergent-divergent focusing operation, but cannot be to carrying out the editor or the preservation of presetting bit record.If during the presetting bit record non-NULL of remote site feedback, directly show the every information of remote site presetting bit.On this interface, can directly use presetting bit, also can directly carry out the focusing operation of convergent-divergent up and down of video camera, but cannot be to carrying out the editor or the preservation of presetting bit record.
In should using, for the situation of multiple spot conversation, corresponding remote site has a plurality of, and the video camera control of remote site is carried out in local meeting-place if desired, then from that remote site request presetting bit information of trend correspondence.
In should using, for the individual meeting site situation of a plurality of video cameras is arranged, and use one identically, to the presetting bit information of far-end request the time, the presetting bit information that far-end returns comprises video camera sequence number and name information etc.
According to should using, no matter idle no talking state, or talking state can be carried out the position setting of local video camera, and is kept at the local terminal as local presetting bit.The information of presetting bit record can comprise critical datas such as meeting place name, meeting-place number, presetting bit title, image.Each terminal is only preserved the presetting bit information of oneself, does not preserve the presetting bit information in other meeting-place.In free time or the talking state, when terminal control this locality or Remote Camera, internal system is extracted local presetting bit information automatically.This presetting bit information can directly be used, and also can carry out edit-modify.In addition, also can not use presetting bit, directly carry out video camera convergent-divergent focus control up and down.In the point-to-point or multiple spot talking state, during terminal control remote site video camera, local meeting-place sends a message to corresponding remote site, asks the presetting bit information of this remote site.If remote site has the presetting bit record, then give local meeting-place by message feedback, local meeting-place then can demonstrate corresponding presetting bit record.The far-end presetting bit can be directly used in local meeting-place, also can directly carry out video camera convergent-divergent focus control up and down.But do not allow local meeting-place to carry out the editor and the preservation of far-end presetting bit record.Under the various situations,, then can only directly carry out video camera convergent-divergent focus control up and down if do not find the presetting bit record.Whether can carry out presetting bit setting and preservation this moment, then the setting when finding presetting bit and to preserve operational constraints consistent.Processing procedure and technical scheme are above being described in detail, no longer describe in detail here.
Use three: network equipment saves presets the position, local meeting-place control video camera.
In should using, the presetting bit information of each meeting-place video camera all oneself is provided with by this meeting-place, then information is sent to network equipment, saves presets a record by this network equipment.When the remote site video camera need be controlled in local meeting-place in conversation, need to send solicited message to network equipment earlier, get access to information after, carry out the application of presetting bit again.
In should using, the actual function that video camera presetting bit server is provided of network equipment can be served as by MCU (MULTIPOINT CONTROL UNIT, i.e. multipoint control unit), GK (GATEKEEPER, i.e. gatekeeper) or other network equipments.For the purpose of convenient, this network equipment can be described as presetting bit server or server later.
In should using, under idle (non-conversation), point-to-point conversation, multiple spot talking state, when this locality/remote site video camera control need be carried out in local meeting-place, enter video camera control interface, its handling process is as shown in figure 11.
At first enter the control interface of video camera, when the video camera in the local meeting-place of control, automatically seek the presetting bit record of coupling, if find the entry of coupling, then show recorded information and presetting bit information that should entry, edit if desired, then edit and preserve the back and use this presetting bit,, then directly use this presetting bit if do not need editor, if do not find the entry of coupling, the space record interface that then on the control interface, shows an acquiescence, if newly-built record, then newly-increased entry, fill in recorded information and presetting bit information, and regulate camera lens to the position that needs, preserve relevant information, to use this presetting bit, if not newly-built record, the camera lens of then directly regulating video camera is to the position that needs.When the video camera of control remote site, send the presetting bit solicited message to the presetting bit server, request presetting bit record, if find the entry of coupling, then show recorded information and presetting bit information that should entry, directly use this presetting bit, if do not find the entry of coupling, then on the control interface, show the space record interface of an acquiescence, control the operation that video camera carries out convergent-divergent focusing up and down then, with the lens location of control video camera.
In should using, every content of presetting bit record with use one similarly, but record number can't help the meeting-place and generates, and is to generate and management by server is unified.
In should using, the presetting bit recorded and stored is in the non-memory cell of easily losing of presetting bit server.What and record overlay strategy of stored record number are all identical with application one.
In should using, each meeting-place all can be provided with the video camera presetting bit in local meeting-place, after being provided with, can send the presetting bit information in this meeting-place to the presetting bit server, is equivalent to the video camera presetting bit information in this meeting-place of registration on server.If presetting bit information is changed in the meeting-place again, then need to report again to server.Local presetting bit information can be selected to preserve or do not preserve in local meeting-place.If preserve, when then local meeting-place drew oneself up video camera, its presetting bit information only needed to extract from local memory cell, does not need to server requests.Hereinafter mainly not preserving local presetting bit information with local meeting-place is the example explanation.
In should using, acquisition methods for the presetting bit record is similar with using two, because presetting bit information all is kept on the presetting bit server, when the video camera of local meeting-place or remote site is controlled in local meeting-place if desired, extract controlled meeting field information earlier as keyword, as meeting place name, meeting-place number etc., keyword for local meeting-place is known, keyword for remote site, then can from call-information, extract, send the presetting bit request message that comprises above-mentioned keyword to server then, after server is received request message, automatically search coupling, the presetting bit in corresponding meeting-place is write down send to local meeting-place by message; If there is not presetting bit information, then returns presetting bit and be empty information.
In should using, when the video camera of the local meeting-place of control, when if the server feedback presetting bit is recorded as sky, the blank presetting bit operation interface that directly shows acquiescence, on this interface, can directly carry out the focusing operation of convergent-divergent up and down of video camera, also presetting bit information can be set directly, this information is given the presetting bit server by information reporting, then newly-increased this record of presetting bit server.When if the server feedback presetting bit is recorded as non-NULL, on this interface, can directly use presetting bit, also can directly carry out the focusing operation of convergent-divergent up and down of video camera, also can directly edit and every information of keeping records, presetting bit information etc., also can select to dispose record, the presetting bit information changing is given the presetting bit server by information reporting, and the presetting bit server then refreshes the corresponding presetting bit record of preserving or deletes processing.
In should using, when control remote site video camera, when if the server feedback presetting bit is recorded as sky, the blank presetting bit operation interface that directly shows acquiescence, on this interface only with directly carry out video camera up and down with the convergent-divergent focusing operation, but do not support the newly-increased of presetting bit and be provided with.When if the server feedback presetting bit is recorded as non-NULL, operation interface directly shows the every information of this presetting bit, on this interface, can directly use presetting bit, also can directly carry out the focusing operation of convergent-divergent up and down of video camera, but not support the editor and the deletion of presetting bit.
In should using, for the situation of multiple spot conversation, corresponding remote site has a plurality of, and the video camera control of remote site is carried out in local meeting-place if desired, then extract that corresponding remote site information automatically as keyword, then to server requests presetting bit information.
In should using, the situation that a plurality of video cameras are arranged for the individual meeting site with use one identically, to the presetting bit information of server requests the time, the presetting bit information that server returns comprises video camera sequence number and name information etc.
According to should using, no matter idle no talking state or talking state can be carried out the position setting of local video camera, and by message this presetting bit information be sent to network equipment, are preserved by network equipment.This network equipment can be MCU, GK or other third party devices, actually is equivalent to a presetting bit information server.The information of presetting bit record can comprise critical datas such as meeting place name, meeting-place number, presetting bit title, image.The information that each terminal can only be provided with the presetting bit record of oneself reports server, and the information of the presetting bit record in other meeting-place is not set.The information of local presetting bit record, local meeting-place can be selected to preserve, and perhaps do not preserve.During both unique difference, when preserve this locality, when controlling local video camera in local meeting-place, can directly extract the presetting bit record from this locality, not need to server requests information, other processing are then identical.The back does not save presets the position with this locality and is recorded as the example explanation.In free time or the talking state, when terminal is controlled local meeting-place video camera, from call-information, extract the information in Be Controlled meeting-place earlier as keyword, as meeting place name, meeting-place number etc., send the message of the request presetting bit record that comprises above-mentioned keyword then to server, after server is received request message, according to keyword, as meeting place name, meeting-place number searching record, if find corresponding presetting bit record, then give local meeting-place by message feedback, local meeting-place then can demonstrate corresponding presetting bit record.Local meeting-place can directly be used this presetting bit record, also can carry out edit-modify.In addition, also can not use presetting bit, directly carry out video camera convergent-divergent focus control up and down.In the point-to-point or multiple spot talking state, during terminal control remote site video camera, extract the information in Be Controlled meeting-place equally, send a request message to server, whois lookup feeds back to local meeting-place after information, local meeting-place then can demonstrate corresponding presetting bit record.The far-end presetting bit can be directly used in local meeting-place, also can directly carry out video camera convergent-divergent focus control up and down.But do not allow local meeting-place to carry out the editor and the preservation of this presetting bit record.Under the various situations,, then can only directly carry out video camera convergent-divergent focus control up and down if do not find the presetting bit record.Whether can carry out the setting and the preservation of presetting bit record this moment, then the setting when finding presetting bit and to preserve operational constraints consistent.Processing procedure and technical scheme are above being described in detail, no longer describe in detail here.
The beneficial effect that the technical scheme of the embodiment of the invention is brought:
1. solved and can't carry out the defective that preset position is preserved at different remote sites specially, make the terminal use with different remote subscriber communication process in, needn't reset presetting bit.
2. increase presetting bit information, comprise the presetting bit name, presetting bit image, the meeting place name in the corresponding meeting-place of presetting bit, meeting-place number etc.Facilitate user's sign like this and distinguish presetting bit, increase the ease for use of function.
