Fig. 3 is the method flow diagram of another volume adjusting method according to an illustrative examples, the volume tune Section method audio and video playing terminal 01 in implementation environment can perform as shown in Figure 1.It can be wrapped referring to Fig. 3 this method flow Include the following steps：
It whether there is mobile object in preset range where step 301, detection terminal.
Since in the embodiment of the present invention, the volume of terminal needs to be adjusted according to terminal and the distance of user, to meet to use The sense of hearing comfort level at family, and under normal conditions, when terminal is fixed, it is the fortune based on user that the distance of terminal and user, which change, It is dynamic, therefore, when terminal meets preset trigger condition, it whether there is mobile object in the preset range where meeting detection terminal, The preset trigger condition can power on for terminal, or terminal commences play out audio and video.Terminal can be in these motive objects Target object is determined in body again, which is defaulted as user.In practical application, which can be human body, Can be the pet that cat, dog etc. can move, it is not limited in the embodiment of the present invention.
Optionally, as shown in figure 4, the step 301 can include：
Step 3011, judge terminal to can detect in scope to whether there is mobile object.
It is exemplary, judge that the process that terminal can detect in scope with the presence or absence of mobile object may include steps of：
Step 3011a, periodicity acquisition terminal can detect the image in scope.
It is exemplary, can by the image collection module that image collection module that terminal carries either is connected with terminal come Obtain terminal and can detect image in scope, which can be camera, in practical application, camera acquisition Image is typically sized to：640 × 480,1024 × 768,1600 × 1200 or 2048 × 1536.Specifically, for difference Camera, the image of acquisition it is of different sizes.In two groups of numerals of imaging, the former is picture width, and the latter is picture Highly.The aspect ratio of the image of acquisition is generally 4：3.The image that the terminal can detect in scope refers to that terminal is able to detect that In the range of in image, for example, can be the image that can be in coverage of image collection module.Wherein, image is obtained Cycle can be the fixed cycle, such as 1 second or 0.5 second, or the variable cycle, for example, two adjacent acquisition cycles lead to Different triggering mode triggerings are crossed, or meet default rule so that the duration in two adjacent acquisition cycles is different.
Step 3011b, the image that the image of current period acquisition was obtained with a upper cycle is compared.
To obtain the cycle as the fixed cycle, and it is exemplified by 0.5 second, the image that current period is obtained before 0.5 second with obtaining The image in a upper cycle be compared, determine that two field pictures whether there is the object of change in location, obtained in current period During the object that existence position changes in the image that image was obtained with a upper cycle, then step 3011c is performed, obtained in current period The image that obtains of image and a upper cycle in when the object of change in location is not present, then perform step 3011a.
It should be noted that the image that terminal compares is typically the image obtained from same angle, if terminal can move Dynamic, then the image that terminal-pair different angle obtains is usually without comparing.
Step 3011c, the thing that existence position changes in the image that the image that current period obtains was obtained with a upper cycle During body, determine that terminal can detect there are mobile object in scope, and the object that mobile object is existence position change.
For example, terminal in same angle shot two images, shape same object generates position in the two images Change, then terminal determines the object that the object is existence position change.
It should be noted that the change in location in the embodiment of the present invention can be the change in location of horizontal direction, can also For the change in location of vertical direction.
In practical application, the quantity of mobile object can be multiple, in the image for obtaining current period and a upper cycle When the image of acquisition is contrasted, the object that all positions can be existed to change is determined as mobile object.
In the embodiment of the present invention, it can also judge that terminal can detect in scope by other means and whether there is motive objects Body, for example, whether there is mobile object in scope using ultrasonic wave to judge that terminal can detect.Wherein, which is a kind of Frequency is higher than 20000 hertz of sound wave, its good directionality, penetration capacity is strong, is easily obtained the acoustic energy relatively concentrated, is often answered For ranging, test the speed etc..It is exemplary, supersonic generator and ultrasonic receiver are provided with terminal, terminal passes through this Supersonic generator periodic transmission ultrasonic signal, wherein, the cycle for launching ultrasonic signal can be the fixed cycle, such as 1 second or 2 seconds, or the variable cycle, for example, two adjacent transmit cycles are triggered by different triggering modes, Huo Zhefu Close default rule so that the duration of two adjacent transmit cycles is different；Terminal is received from return by ultrasonic receiver Ultrasonic reflections signal；Terminal compared the ultrasonic reflections signal that current period receives and the ultrasound that a upper cycle receives Wave reflection signal, judges whether mobile object；If the ultrasonic reflections signal that current period receives and a upper cycle The ultrasonic reflections signal received is different, then judges that there are mobile object；If the ultrasonic reflections that current period receives Signal is identical with the ultrasonic reflections signal that a upper cycle receives, then judges mobile object is not present.
To launch cycle of ultrasonic signal as the fixed cycle, and exemplified by 1 second, terminal current period to be received super Sound wave reflected signal is contrasted with the ultrasonic reflections signal received before 1 second, if two ultrasonic reflections signals Waveform generates change, then judges that there are mobile object.If the waveform of two ultrasonic reflections signals does not produce change, Then judge mobile object is not present.
It should be noted that the ultrasonic signal that terminal compares is from the transmitting of same angle and received signal, if eventually End can move, then the transmitting of terminal-pair different angle and received signal are usually without comparing.
Step 3012, can detect in scope there are during mobile object in terminal, obtain the image for including mobile object.
It is exemplary, can by the image collection module that image collection module that terminal carries either is connected with terminal come Obtaining includes the image of mobile object, which can be camera, should include the image of mobile object and can be The terminal of the acquisition of camera can detect the image in scope, and the terminal can detect in the image in scope includes motive objects Body.
Step 3013, basis include the image of mobile object, determine the default model whether mobile object is in where terminal In enclosing.
Specifically, according to the image including mobile object, the preset range whether mobile object is in where terminal is determined Interior method, may include steps of：
Step 3013a, detection is included in the image of mobile object, the similarity of mobile object and the reference substance of default size Whether correlation is less than default correlation threshold value.
Wherein, the similarity correlation and similarity are negatively correlated, it is, when mobile object and the reference substance of default size Similarity correlation it is smaller when, the similarity of mobile object and the reference substance of default size is higher, both similar masters Show as the similar of size.
It is not specifically limited, can be set according to actual conditions default for the default correlation threshold value embodiment of the present invention Correlation threshold value, in practical application, which could be provided as 10.
Optionally, the image including mobile object is determined as target image, in target image is detected mobile object with Before whether the similarity correlation of the reference substance of default size is less than default correlation threshold value, can first it be built in the target image Vertical image coordinate system, calculates the similarity correlation of mobile object and the reference substance in the image coordinate system, exemplary, false If the origin of the image coordinate system is the upper left corner of the target image, in the coordinate system, the positive direction of x-axis is in the horizontal direction Direction to the right, the positive direction of y-axis is direction vertically downwards, correspondingly, mobile object is similar to the reference substance Spending correlation value calculation formula can be：
