Description

The method for switching resolution ratio in video call system and video calling

Technical field

The present invention relates to switch the implementation method of resolution ratio in a kind of communication field, more particularly to a kind of video calling.

Background technology

With the development of communication, video calling is increasingly popularized.The terminal device of video calling can be carried out to be had a lot, such as Common computer, mobile phone, intelligent television, TV box etc..For the terminal of similar TV box, if terminal is not carried taken the photograph As head, a camera will be in addition configured when carrying out video calling.Present equipment interface is all standard criterion, is such as imaged Head is coupled with TV box generally by USB interface.Terminal manufacturer is more, and camera manufacturer is also more, technology It is uneven, cause the presence of very big difference on electric property, interface specification.This generates adaptation issues.

The problem for currently encountering is, the terminal such as TV box sometimes cannot normal acquisition to camera in a certain resolution ratio Video data, in video calling, if camera just have selected the resolution ratio that normally can not be gathered by terminal, may result in Terminal cannot display picture, bring very big puzzlement to user, think that equipment is out of joint, affect Consumer's Experience.

The content of the invention

It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of video call system, and regard Frequency switches resolution ratio method in conversing, intelligence switching camera is unable to normal acquisition and the resolution picture for showing, to user Bring new convenience.The technical solution used in the present invention is:

A kind of video call system, is provided with resolution ratio abnormality detection with switching mould in the video call terminal of the video call system Block;

Described resolution ratio abnormality detection and handover module, comprising following submodule:

Module is surveyed in camera initialization, for initializing camera, calls anomaly resolution rate detection module detection camera current The video data of resolution ratio whether normal acquisition, decides whether to carry out resolution ratio of camera head switching according to testing result;Work as detection As a result show camera current resolution video data cannot normal acquisition, then call resolution adaptation module, select different In current resolution another resolution ratio as initialization camera parameter;

Anomaly resolution rate detection module, for detecting the video data of camera current resolution whether normal acquisition;

Resolution ratio acquisition module, obtains all resolution ratio that camera is supported;

Resolution adaptation module, in the resolution ratio supported from camera, deletes known anomaly resolution rate, and according to arranging one is chosen Individual suitable resolution ratio;

Detection setup module, for user the setting of anomaly resolution rate detection is changed.

A kind of method for switching resolution ratio in video calling, it is adaptable to above-mentioned video call system, including:

Camera initialization is surveyed module and carries out the initialized method of camera, is comprised the following steps:

Step 301, starts;

Step 302, arranges resolution picture detection mark;

Step 302, removing has detected number of times;

Step 304, removes resolution ratio and normally indicates;

Step 305, obtains resolution parameter, and with the resolution parameter camera is opened;

Step 306, judges whether camera is successfully opened, and is, goes to step 307, no, goes to step 313;

Step 307, judges resolution picture detection mark, if detection terminates, and is to go to step 310, no to go to step 308;

Step 308, obtains the video data of camera to buffering area;

Step 309, calls anomaly resolution rate detection module, using the video data of buffering area as parameter, carries out resolution ratio correspondence The detection of video data;Go to step 307;

Step 310, judges that resolution ratio normally indicates, the video data of current resolution whether can normal acquisition, be to go to step 314, it is no, go to step 311;

Step 311, calls resolution adaptation module, selects another resolution ratio for being different from current resolution as initial Change the parameter of camera;

Step 312, closes camera, goes to step 302;

Step 313, closes camera;

Step 314, terminates.

Further, in step 309, anomaly resolution rate detection module is called, carries out the inspection of resolution ratio correspondence video data The method of survey is as follows:

Step 401, starts;

Step 402, reading video data parameter buffer;

Step 403, reads needing in arranging and detects number of times;

Step 404, judgement has currently detected number of times, if be to go to step 408 more than or equal to needing to detect number of times, no, turn step Rapid 405;

Step 405, has detected that number of times plus 1;

Step 406, in judging video data buffer area, if having data to change, be, goes to step 407, no, goes to step 410;

Step 407, arranges resolution ratio and normally indicates, goes to step 409;

Step 408, removes resolution ratio and normally indicates;

Step 409, removes resolution picture detection mark;

Step 410, terminates.

Further, in step 311, call resolution adaptation module carry out resolution adaptation method it is as follows:

Step 501, starts;

Step 502, obtains current resolution parameter;

Step 503, obtains the resolution list that camera is supported;

Step 504, is ranked up to resolution list;

Step 505, known anomaly resolution rate is deleted from resolution list;

Step 506, reads the resolution adaptation condition for arranging;

Step 507, judges resolution adaptation condition, if selects to be more than current resolution, is to go to step 508, no, goes to step 509;

Step 508, from the resolution ratio more than current resolution, selects minimum resolution ratio;Go to step 510;

Step 509, from the resolution ratio less than current resolution, selects maximum resolution ratio;

Step 510, using the resolution ratio chosen as current resolution parameter;

Step 511, terminates.

Further, present invention additionally comprises carrying out the method that the detection of anomaly resolution rate is arranged, bag using detection setup module Include following steps:

Step 701, starts;

Step 702, receiving user carries out the order that the detection of anomaly resolution rate is arranged;

Step 703, shows that the detection of anomaly resolution rate arranges interface, points out user to be operated;The detection of anomaly resolution rate arranges boundary Face includes detecting number of times and resolution adaptation condition;

Step 704, judges whether user performs setting operation, is to go to step 705, no, goes to step 707;

Whether step 705, judge to arrange and change, and is to go to step 706, no, goes to step 707;

Step 706, preserves the detection of anomaly resolution rate and arranges;

Step 707, hides the detection of anomaly resolution rate and arranges interface;

Step 708, terminates.

It is an advantage of the current invention that:Using the present invention, in video calling, the resolution ratio of current setting cannot normally show picture During face, in time the video data of detection current resolution whether normal acquisition, according to testing result correct camera is switched to Resolution ratio, it is to avoid bring unnecessary puzzlement to user, always brings more preferable video calling to experience to user.
