The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.
As shown in fig. 1, an embodiment of the present invention provides a method for storing photo information, which specifically includes the following steps:
and 102, the terminal equipment adds the sensor information to the photo information corresponding to the photo.
Through the scheme, the photo is shot through the camera according to the terminal equipment, the sensor information of the equipment sensor is collected in real time in the shooting process, the collected sensor information is added into the photo information corresponding to the photo, the content of the photo information is increased, the limitation of the photo information is reduced, and meanwhile the sensor information can be conveniently checked and called in the later stage.
The device sensors include, but are not limited to, some or all of the following sensors:
the sensor comprises a gyroscope sensor, an acceleration sensor, a magnetic resistance sensor, a direction sensor, a pressure sensor, a temperature sensor and a light sensor.
In practice, there are many ways for the terminal device to determine the sensor information of the device sensor when taking the picture, and one way is listed below:
first, a sensor manager is created.
The terminal equipment establishes a sensor manager through a sensorMange interface, obtains all sensor lists from the sensor manager, and can determine the types of equipment sensors arranged in the equipment, wherein specific codes are as follows:
SensorMange sm＝(SensorManager).getSystemService(SENSOR_SERVICE)。
and secondly, registering a monitor for the specific equipment sensor.
The listener, i.e., the listening function, registers the listening function to monitor the device sensor for changes in sensor information.
In the embodiment of the invention, many device sensors, such as a gyroscope sensor, an acceleration sensor, a magnetoresistive sensor and the like, are involved in the process of taking a picture, and two schemes are provided when a monitor is registered for the device sensor.
Registration scheme 1, a snoop function is registered for each device sensor.
After the list of device sensors is acquired by the sensor manager, the device sensors used in the shooting process are determined, and a listener is registered for each device sensor to be used.
According to the scheme, the device sensors arranged for different devices are different, and the registration process is too complicated under the condition.
Registration scheme 2, only one snoop function is registered.
When registering a monitoring function, a parameter is predefined for judging the type of the equipment sensor, if other types of equipment sensor monitors need to be registered, the type of the equipment sensor is changed by directly changing the parameter value, and the registration of other equipment sensor monitors is realized.
Type _ origin registration listener is for example a magnetoresistive sensor, i.e.:
sm,registerListener(this,sm.getDefaultSensor(Sensor.TYPE_ORIENTATION),SensorManager.SENSOR_DELAY_FASTEST)。
the first parameter is used for judging the type of the sensor, and when the GYROSCOPE sensor monitor is registered, the sensor attribute of the first parameter value is changed into sensor.
sm,registerListener(this,sm.getDefaultSensor(Sensor.TYPE_GYROSCOPE),SensorManager.SENSOR_DELAY_FASTEST)。
And thirdly, acquiring sensor information through a callback function.
The three equipment sensors are provided with x, y and z axes, and sensor information, namely specific data of the coordinate axes, is acquired through a callback function.
As shown in FIG. 2, the acceleration sensor returns acceleration data for three axes x, y, and z, which contains the effect of gravity in m/s ^ 2. The mobile phone is horizontally placed on a desktop, the x axis is defaulted to 0, the y axis is defaulted to 0, and the z axis is defaulted to 9.81. The cell phone was placed on the desktop with the z-axis at-9.81. If the data of the acceleration sensor is changed from (0.3, 0.2, 8.7) to (1.2, 1.3, 9.5) due to hand shake in the process of taking a picture by using the mobile phone, the acceleration data in the process of taking the picture is acquired through the OnSensorChanged callback function.
In the embodiment of the present invention, the listener needs to perform a task of monitoring sensor information during shooting, but the listener does not need to monitor the sensor information any more after shooting is completed, and optionally, the registered device sensor listener may be logged out after the sensor information is acquired through a callback function, so that power consumption of the device may be reduced.
In implementation, after the sensor information is acquired through the callback function, the terminal device determines that the sensor information of at least one device sensor changes in the process of taking the picture, and adds the changed sensor information to the picture information corresponding to the picture.
Optionally, if the device sensor includes an acceleration sensor and/or a gyroscope sensor, since the acceleration sensor and the gyroscope sensor are both multi-axis sensors, after the sensor information is obtained through the callback function, the deviation may be calculated according to the change of the axis vector, and the degree of deviation of the axis vector is added to the photo information corresponding to the photo.
Taking an acceleration sensor as an example, x is 0.62, y is 2.15, z is 9.78 before photographing, sensor information when photographing is 2.25, y is 4.86, z is 8.50, and the deviation degree of the axis vector of the acceleration z axis is (9.78-8.50)/9.78-13% when looking at the z axis alone.
According to the method, the deviation value of the axial vector is directly added to the photo information corresponding to the photo, and the change of the sensor information in the photographing process is more intuitively reflected. In the shooting process, sensor information of the equipment sensors is not changed sometimes, for example, a stable bracket is used for fixing equipment, in this case, the shooting quality of the picture is high, and the picture does not need to be processed in the later period, so that the embodiment of the invention adds the changed sensor information to the picture information corresponding to the picture after the terminal determines that the sensor information of at least one equipment sensor is changed in the shooting process of the picture.
Optionally, after the sensor information is obtained through the callback function, there are many ways in which the terminal device adds the sensor information to the photo information corresponding to the photo, and the following are listed as some:
the adding mode is one, and the adding mode is directly added through a callback function.
After the terminal equipment acquires the sensor information through the callback function, the terminal equipment directly calls an exif interface in the callback function to write the sensor information into a correct position.
According to the method, the terminal equipment can directly call the exif interface after acquiring the sensor information, and the exif is a good interface, so that the sensor information acquired by the callback function can be automatically written to a correct position only by transmitting the sensor information.
And adding the second mode through other functions.
And after the terminal equipment acquires the sensor information through the callback function, storing the acquired sensor information, and then adding the sensor information to the photo information corresponding to the photo through other functions.
For example, after acquiring sensor information through a callback function in the process of taking a picture, the exif interface is called to add the sensor information to an image file data stream (writeExif) in a format when the onPictureTaken processes raw image data.
According to the method, the sensor information needs to be stored through the callback function, the exif interface is called in other functions of the main thread to write the sensor information to the correct position, and the offset needs to be calculated when the other functions in the main thread are added, so that the exif interface writing is realized.
In implementation, after the terminal device obtains the sensor information through the callback function, the sensor information needs to be saved, where there are many ways to save the sensor information, and the following list is some.
The first storage mode is as follows: added to a separate file.
After the terminal equipment acquires the sensor information through the callback function, the sensor information and other photo information are respectively stored in different files, and at this time, no extension field needs to be newly added, but the sensor information is separately stored, which is not beneficial to searching of post-processing.
And (2) a second storage mode: and adding the extension field of the photo information corresponding to the photo.
As shown in fig. 3, a common storage format when taking a photo is JEPG (Joint Photographic expert group, JEPG is an image format specified by Joint Photographic expert group), where photo information includes file header information and image data, and after a terminal device acquires sensor information through a callback function, the sensor information is added to an extension field of the photo information corresponding to the photo.
There are many ways to extend the field, and the following lists several ways:
in the extension mode 1, an extension field is added after the header information Exif.
As shown in fig. 4A, after the sensor information is acquired through the callback function, the Exifinterface interface is directly called in the callback function to add the sensor information to the extension field after the file header information.
The extension method 2 is to directly extend header information Exif and add several sets of IFDs (Image File Directory).
As shown in fig. 4B, after the sensor information is acquired by the callback function, the exif interface is called directly in the callback function to add the sensor information to the IFD extension field in the file header information.
It should be noted that the extension manner of the newly added extension field listed in the embodiment of the present invention is only an example, and any extension manner of the newly added extension field is applicable to the present invention.
In implementation, after the sensor information in the shooting process is stored in real time, the sensor information can be used for algorithm parameter adjustment in later image processing.
For example, when a photo is taken, sensor information of equipment in the shooting process is recorded together, and information such as angles, displacements, external light intensity and the like in the imaging process is recorded by using sensor information such as a gyroscope sensor, an acceleration sensor and the like of the mobile equipment, and then a newly added extension field is recorded. During the post-image processing, the shake degree during the photo taking can be judged according to the information such as the angle, the displacement and the like, and the deblurring processing can be carried out on the photo according to the shake degree.
Taking the example of deblurring a photo according to sensor information of the photo, as shown in fig. 5, the related flow operations include:
step 500: the terminal equipment determines that a new photo is added into the gallery;
step 501: the terminal equipment judges whether the photo information corresponding to the photo contains a sensor field, if so, the step 502 is executed, otherwise, the process is ended;
step 502: the terminal equipment analyzes the sensor field to obtain sensor information;
step 503: the terminal equipment judges whether the jitter degree is larger than a threshold value according to the sensor information, if so, the step 504 is executed, otherwise, the process is ended;
step 504: the photo is deblurred and the processing flag is saved to the extension field.
As shown in fig. 6, an embodiment of the present invention provides an apparatus for storing photo information, where the apparatus includes: a processor 600 and a memory 601, wherein the memory 601 stores program codes, and when one or more computer programs stored in the memory 601 are executed by the processor 600, the terminal device is caused to execute the following processes:
