The shooting anti-shake processing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
In an embodiment of the present application, a shooting anti-shake processing method is provided, please refer to fig. 1, which is a schematic flow chart of the shooting anti-shake processing method according to the embodiment of the present application.
As shown in fig. 1, the method for processing text input by an input method according to the embodiment of the present application includes the following steps:
The historical shooting shaking data is shaking data statistics of a same user in a preset historical period time period before the shooting time of the same user currently using the terminal device, for example, the shooting shaking data of the user in a month before the current shooting time can be counted, the historical shooting shaking data can be based on shooting statistics of the user using the same current terminal device, shaking information collected when the user uses other terminal devices for shooting can be included, and the shaking information is transmitted to the current terminal device based on cloud and the like.
In the present application, there may be a plurality of users using the same terminal device, and each user has corresponding history shooting shake data. The historical shooting jitter data of different users can be stored correspondingly by distinguishing the users.
In order to distinguish different users and obtain the historical shooting shaking data of the users, optionally, before obtaining the historical shooting shaking data of the users when shooting with the terminal device, the method further includes: acquiring biological characteristic information of the user; and determining the historical shooting shaking data of the user at the terminal equipment according to the biological characteristic information of the user. The biometric information of the user is, for example, fingerprint information and/or face information of the user, and the fingerprint or face is a unique identifier unique to each person, so that by identifying the unique identifier of the user currently photographed using the terminal device, that is, determining the feature information of the user, the uniqueness of the corresponding user can be determined. The historical shooting shaking data of different users can be correspondingly stored according to the characteristic information of the users.
Optionally, the historical shooting shake data may be a plurality of gyroscope (Gyro) data collected within a predetermined time period when the user uses the terminal device to shoot, for example, three-axis attitude angles or angular velocities generated by hand shake when the user holds the terminal device to shoot. And storing the acquired Gyro data locally or uploading the Gyro data to a cloud for storage so as to be used for subsequent determination of the anti-shaking degree.
The terminal device may be a mobile phone, a camera, or the like having a photographing function.
And 204, adjusting a preset cutting proportion corresponding to the anti-shake function in the terminal equipment according to the historical shooting shake data of the user in the terminal equipment.
Optionally, in an embodiment, adjusting a predetermined cropping ratio corresponding to an anti-shake function in the terminal device according to the history shooting shake data includes: determining the historical shaking degree of the user according to the historical shooting shaking data; and adjusting a preset cutting proportion corresponding to the anti-shake function in the terminal equipment according to the historical shake degree of the user.
Specifically, determining the historical shaking degree of the user according to the historical shooting shaking data comprises the following steps: and determining an average Gyro value of the user according to a plurality of Gyro data included in the historical shooting shake data, and determining the shake degree of the user according to the average Gyro value.
For example, when a user uses the terminal device to take a picture each time, the corresponding triangular attitude angle or angular velocity of the user when taking a picture is collected through the Gyro data sensor in the terminal device and stored. By averaging these historical Gyro data saved, an average Gyro value, such as an average angular rate value, corresponding to the user can be determined. The calculated average Gyro value can be used for representing the shaking state of the user using the terminal equipment during usual shooting, so that the shooting habit of the user can be known. The larger the average Gyro value is, the larger the shaking angle of the user in the shooting process is, and the more violent the shaking degree is; conversely, a smaller average Gyro value indicates that the user shakes at a smaller angle during shooting, and the shake is more slight. In the case where the user performs photographing after supporting the terminal device using a fixing device such as a tripod substantially every time, the average Gyro value obtained may be approximately 0, that is, the user is substantially stationary during photographing and there is no shake.
The historical shaking degree of the user is determined by collecting the Gyro data of the user, the user can be accurately photographed, the photographing habit and the photographing level of the user are determined, and the proper cutting proportion of the user can be accurately adjusted according to the shaking degree of the user in the follow-up process.
In the conventional EIS electronic anti-shake processing, the default cropping ratio is fixed and unchanged, and the shooting shake degrees of different users may have great difference, so that the processing effect of the shooting anti-shake function is poor due to the conventional fixed cropping ratio.
In one embodiment, according to the historical shaking degree of the user, the preset cutting proportion corresponding to the anti-shaking function in the terminal equipment is adjusted, and the preset cutting proportion comprises at least one of the following items: when the shaking angle corresponding to the historical shaking degree is larger than the maximum anti-shaking angle of the anti-shaking range corresponding to the preset cutting proportion, adjusting the preset cutting proportion to be a first cutting proportion, wherein the first cutting proportion is larger than the preset cutting proportion; and when the shaking angle corresponding to the historical shaking degree is smaller than the minimum anti-shaking angle of the anti-shaking range corresponding to the preset cutting proportion, adjusting the preset cutting proportion to be a second cutting proportion, wherein the second cutting proportion is smaller than the preset cutting proportion.
In this way, the preset cutting proportion of the currently used terminal equipment is adaptively increased or decreased according to the magnitude of the shaking degree of the history shot by the user.
By analyzing and storing the data record of Gyro in the previous shooting process of the user, the shaking habit of the user in the shooting process is continuously learned and known, so that the cutting proportion of the EIS of the user is continuously optimized, and the anti-shaking effect is dynamically set according to the shooting habit of the user.
Different users have different shake degrees during shooting, for example, some users have large shake degrees during shooting, some users have small shake degrees when being professional, and some users always use a tripod to shoot, so that the shake is basically 0; alternatively, the shake degree of the same user in different shooting periods may also vary, for example, the user has a higher shake degree in shooting at the initial stage due to a lower level, but as the user continuously learns that the shooting level of the user is higher, the statistical shake degree in the predetermined time period after the level is higher is smaller.
In the embodiment of the application, the preset cutting proportion of the terminal device for anti-shake is, for example, a default cutting proportion set by a factory, so that after the shaking habit shot by the user is determined according to the historical shaking degree corresponding to the user, the default cutting proportion of the terminal device for anti-shake is adaptively adjusted to be increased or decreased.
The anti-shake range corresponding to the predetermined clipping ratio is located between the maximum anti-shake angle and the minimum anti-shake angle, as described above, when the shaking angle corresponding to the historical shaking degree of the user is determined to be larger than the maximum anti-shaking angle of the anti-shaking range corresponding to the preset cutting proportion, for example, the default clipping ratio is set to 20%, and the default clipping ratio corresponds to an anti-shake range of a ° to b °, where a ° is the minimum anti-shake angle, b ° is the maximum anti-shake angle, that is, the default cropping ratio may prevent the shaking of angles between a and b, and the Gyro data of the user indicates that the user shakes at an angle greater than b, the anti-shake effect during shooting is not good enough, and it is necessary to increase the default cropping ratio appropriately, for example, to adjust the default cropping ratio to a first cropping ratio, which is larger than the default cropping ratio, so as to obtain a larger anti-shake angle, and a user who shoots more shakes can shoot a video with a good anti-shake effect.
On the contrary, when it is determined that the shaking angle corresponding to the historical shaking degree of the user is smaller than the minimum anti-shaking angle of the anti-shaking range corresponding to the preset cutting proportion, and the Gyro data of the user indicates that the shaking angle is smaller than a °, the anti-shaking effect when the user shoots is good, the default cutting proportion can be properly reduced, for example, the default cutting proportion is adjusted to be the second cutting proportion, and the second cutting proportion is smaller than the default cutting proportion, so as to obtain a shot picture with higher quality.
In one embodiment, a plurality of shift positions may be provided for adjusting the predetermined clipping ratio, for example, the clipping ratio of at least one shift position may be set up and down, respectively, based on the predetermined clipping ratio. The cutting ratio corresponding to the anti-shake function may include, for example, 3 th gear, 5 th gear, and the like, and may be specifically adjusted and determined according to the actual situation, and the application is not limited to this specific embodiment.
Optionally, the adjusting, according to the historical shaking degree of the user, a predetermined cutting ratio corresponding to an anti-shaking function in the terminal device includes at least one of:
when the shaking angle corresponding to the historical shaking degree is determined to be in a first anti-shaking range, adjusting the preset cutting proportion to be a third cutting proportion corresponding to the first anti-shaking range, wherein the first anti-shaking range is located between a first maximum anti-shaking angle and a first minimum anti-shaking angle;
when the shaking angle corresponding to the historical shaking degree is determined to be in a second anti-shaking range, adjusting the preset cutting proportion to be a fourth cutting proportion corresponding to the second anti-shaking range, wherein the second anti-shaking range is located between a second maximum anti-shaking angle and a second minimum anti-shaking angle,
the first maximum anti-shake angle is smaller than the second minimum anti-shake angle, and the third cutting proportion is smaller than the fourth cutting proportion.
That is to say, if the predetermined cutting ratio is the default cutting ratio, the maximum cutting ratio, which is the maximum cutting ratio, corresponding to the anti-shake function of the terminal device can be set for the user with the larger historical shake degree to perform anti-shake adjustment, and the minimum cutting ratio, which is the minimum cutting ratio, corresponding to the anti-shake function of the terminal device can also be set for the user with the smaller historical shake degree to perform anti-shake adjustment. An intermediate cutting proportion value can be set between the default cutting proportion and the maximum cutting proportion as required, and a plurality of intermediate cutting proportion values can be set between the default cutting proportion and the minimum cutting proportion. Of course, the intermediate cut ratio value may not be set.
Reference may be made to fig. 2a and 2b regarding a relationship between a default cropping ratio, a maximum cropping ratio, and a size of an original size of an image captured by a user using a terminal device, where fig. 2a and 2b are schematic diagrams of a display interface of the terminal device for a cropping ratio corresponding to an anti-shake function according to an embodiment of the present application.
As shown in fig. 2a, when the EIS automatic anti-shake switch of the terminal device is turned on, the clipping ratio and the maximum clipping ratio are defaulted. While the crop scale is set, the user may be presented with a display of the approximate field angle range of view through the capture display interface of FIG. 2b, as indicated in phantom.
As shown in fig. 2b, on the shooting display interface of the terminal device, a default cut, that is, a default cut proportion of 20%, and a maximum cut, that is, a maximum cut proportion of 35%, are given. Here, the minimum clipping ratio may be 0.
When the anti-shake effect needs to be obtained, if the shake angle corresponding to the historical shake degree of the user falls within the anti-shake range of the default cutting proportion, adjustment is not needed, and the picture cutting is carried out on the shot image with the original size according to the default cutting proportion. If the shaking angle corresponding to the historical shaking degree of the user exceeds the maximum anti-shaking angle corresponding to the anti-shaking range of the default cutting proportion, the default cutting proportion can be adjusted to be increased, but the default cutting proportion can be adjusted to be the maximum cutting proportion at most, and the picture cutting is carried out to realize the anti-shaking shooting function. As shown in fig. 3, fig. 3 is a schematic view of a shooting scene of a terminal device according to a first embodiment of the present application.
So, anti-shake effect is not good enough when the user shoots, then suitably increases acquiescence cutting proportion, reduces the angle of view, obtains bigger anti-shake angle, can let the user of comparatively trembling when shooing also can shoot out the fine photo or the video of anti-shake effect. If the shooting capability of the user is continuously improved, the default cropping proportion is gradually reduced at the back, so that the user can shoot works with good anti-shake effect and large field angle.
If the shaking angle corresponding to the historical shaking degree of the user is lower than the minimum anti-shaking angle corresponding to the anti-shaking range of the default cutting proportion, the default cutting proportion can be adjusted to be reduced, but the default cutting proportion can be adjusted to be the minimum cutting proportion at most, and the picture cutting is carried out to realize shooting anti-shaking.
The above embodiment describes a case where the terminal device has a single camera with multiple adjustable cropping proportions, and the corresponding anti-shake adjustment mode is single-shot independent adjustment. If the user still takes a picture and the jitter reaches the upper limit of the cropping ratio of the field angle, the user cannot adjust the picture.
The present terminal device is generally configured with three cameras such as tele, main, wide, the field angles of which are sequentially increased.
Therefore, in another embodiment, the terminal device of the present application may have a plurality of cameras, and each camera may have a plurality of adjustable cropping ratios, respectively, so that the user may be subjected to anti-shake with a multi-camera cooperation. As shown in fig. 4, fig. 4 is a schematic view of a shooting scene of a terminal device according to a second embodiment of the present application.
Optionally, the terminal device used by the user for shooting includes a plurality of cameras respectively corresponding to different preset cropping proportions, and the preset cropping proportion corresponding to the anti-shake function in the terminal device is adjusted according to the historical shake degree of the user, including: when the shaking angle corresponding to the historical shaking degree is determined to be in a first anti-shaking range, adjusting the preset cutting proportion to a first preset cutting proportion corresponding to the first anti-shaking range; after the preset cutting proportion corresponding to the anti-shake function in the terminal equipment is adjusted according to the historical shake degree of the user, the method further comprises the following steps: and controlling a first camera to acquire an image according to the first preset cutting proportion, wherein the first camera corresponds to the first preset cutting proportion.
The first camera may be a currently enabled camera or a currently enabled second camera, but the second camera does not correspond to the first preset cropping proportion, and the first camera corresponds to the first preset cropping proportion, so that the camera is switched from the second camera to the first camera by controlling the first camera to collect an image, and accordingly, the preset cropping proportion corresponding to the camera is also adjusted.
As described above, the predetermined cropping ratio may be a factory-set default cropping ratio. A plurality of cameras that terminal equipment includes have different acquiescence cutting proportion respectively, and every acquiescence cutting proportion corresponds different anti-shake scope.
According to the shaking angle of the user during the historical shooting, represented by the Gyro data of the user, the angle can be determined to be in the first anti-shake range or the second anti-shake range, so that the anti-shake cropping proportion of the terminal equipment can be determined to be adjusted to be the default cropping proportion of the first camera or the second camera, wherein each camera further has a plurality of adjustable cropping proportions, for example, the first camera comprises the default cropping proportion, at least one gear cropping proportion larger than the default cropping proportion and/or at least one gear cropping proportion smaller than the default cropping proportion.
Taking as an example that different cameras are respectively configured with different default cropping proportions and the maximum cropping proportion larger than the default cropping proportions, the camera with the larger field angle has the maximum cropping proportion. For example, the default cropping percentage of the tele camera is 10%, and the maximum cropping percentage is 25%; the default cutting proportion of the main camera is 20%, and the maximum cutting proportion is 40%; the default cropping proportion of the wide-angle camera is 30%, the maximum cropping proportion is 50%, and the like. Of course, there may also be at least one intermediate cropping ratio between the default cropping ratio and the maximum/minimum cropping ratio for each camera. For example, an intermediate cropping percentage of 30% is also provided between the default cropping percentage of 20% and the maximum cropping percentage of 40% for the main camera.
Of course, the above specific data are only used as examples, and the application is not limited to the specific embodiment.
By analyzing the jitter degree of the Gyro data of the current shooting user, it is determined that the jitter angle corresponding to the jitter degree of the user in the shooting process is large and reaches the maximum cutting proportion of the currently used camera, for example, when the maximum cutting proportion of the telephoto camera reaches 25%, the cutting proportion corresponding to the anti-shake function shot by the user can be set as the middle cutting proportion of 30% of the main camera.
Meanwhile, the camera for taking pictures is set to be the camera with a larger field angle in a default mode, a larger cutting proportion is obtained, and a better anti-shaking effect is achieved. When the current camera is switched from the telephoto camera to the main camera, the field angle of the main camera is originally larger than that of the telephoto camera, so that the field angles in the shooting pictures are close when a larger cropping proportion is used in the main camera in the camera switching process, and the smooth switching effect can be achieved.
With the same angle of view, the main camera can cut more pictures to improve the anti-shake effect. Similarly, if the main camera has been adjusted to the maximum cutting proportion, the wide-angle camera is switched to the anti-shake cutting with a larger proportion. If the wide-angle camera has the maximum cutting proportion, the wide-angle camera cannot be continuously lifted.
Similarly, if the shooting level of the user is increased, the corresponding cropping proportion can be adjusted to the cropping proportion suitable for the current shooting level of the user according to the default cropping proportion of different cameras and the size of each set cropping proportion of a single camera and the historical shaking degree of the user.
According to the method and the device, the historical shooting shaking data of the user are obtained when the user uses the terminal equipment to shoot, and the preset cutting proportion corresponding to the anti-shaking function in the terminal equipment is adjusted according to the historical shooting shaking data of the user. Therefore, the anti-shaking strength of the terminal equipment can be adjusted by automatically adjusting the cutting proportion of the picture according to the history shooting shaking habit of the user, so that different users can automatically acquire the optimal anti-shaking effect, and the electronic anti-shaking processing effect is improved.
In addition, in the process that the photographing capability of the user is continuously improved, the anti-shake cutting proportion is automatically adjusted by collecting the Gyro data, so that the anti-shake effect of the terminal equipment is also continuously improved. When the shooting capability of the user is enhanced, the shaking effect of the user is automatically weakened, and a wider visual range is brought to the user.
The shooting anti-shake processing method can dynamically set the anti-shake cutting proportion according to different user types, and can be used for distinguishing users who are not likely to take pictures and have severe habitual hand shake, professional shooting people or users who often use tripods to shoot or have low requirements on anti-shake effects, so that the requirements of customers can be more widely met.
