The mobile terminal 100 includes a water environment sensor 10, a camera system 20, and a processor 30, and the mobile terminal 100 may operate in an underwater mode. The control method according to the embodiment of the present application can be implemented by the mobile terminal 100 according to the embodiment of the present application. Wherein, step 01, step 02 and step 03 can be implemented by the processor 30. That is, the processor 30 is configured to: in the underwater mode, the camera system 20 is turned on in response to user input; searching a camera parameter corresponding to a current sensor signal output by the water environment sensor 10 in a water environment-camera parameter database; the camera parameters are applied to the camera system 20.
According to the control method and the mobile terminal 100, in the underwater mode, the camera parameters can be determined through the current sensor signals and the water environment-camera parameter database, so that the imaging quality can be ensured, and the user experience is improved.
Specifically, the user may use the mobile terminal 100 underwater. In one embodiment, the mobile terminal 100 may include a plurality of operating modes, such as a terrestrial mode and a marine mode, and the mobile terminal 100 may automatically switch the operating modes. The water environment sensor 10 may be always in an on state, acquire environmental information, and determine whether the mobile terminal 100 is underwater. If it is recognized that the current environment is changed from the land to the underwater environment, the mobile terminal 100 may be automatically switched from the land mode to the underwater mode, which may facilitate the user to use the mobile terminal 100 underwater.
Referring to fig. 2 and 3 again, the user may take a picture or photograph under water using the mobile terminal 100. The camera system 20 includes a camera that may be disposed on a front surface of the mobile terminal 100 so that a user can use the camera for self-photographing underwater. A camera may also be provided at the rear of the mobile terminal 100 so that a user can photograph a scene underwater using the camera. The camera system 20 may further include 2 cameras, and the 2 cameras are respectively disposed on the front and the back, which is not limited herein.
When the user uses the mobile terminal 100 underwater, the mobile terminal 100 enters an underwater mode, and the user may trigger a photographing virtual key or press a photographing button to turn on the camera system 20. The water environment sensor 10 may output a current sensor signal, may search for a camera parameter corresponding to the current sensor signal in the water environment-camera parameter database using the current sensor signal, and then apply the camera parameter to the camera system 20.
Therefore, the water environment sensor 10 can be used for acquiring the current sensor signal in real time, and the current sensor signal can reflect the current shooting environment. The camera system 20 can be adjusted by generating appropriate camera parameters in combination with the current shooting environment, so that the imaging quality of underwater shooting can be improved, and a user can conveniently, conveniently and quickly complete underwater shooting actions.
In some embodiments, the water environment-camera parameter database includes a mapping relationship between the calibrated sensor signal and the calibrated camera parameter. Therefore, the same or the closest calibration sensor signal can be searched by comparing the current sensor signal with the calibration sensor signal. The calibrated sensor signal corresponds to calibrated camera parameters, which can be obtained as calibrated camera parameters corresponding to the current sensor signal, and then the calibrated camera parameters are applied to the camera system 20 as camera parameters. In this way, camera parameters can be adjusted according to the underwater environment. The speed of generating the camera parameters can be improved by setting the mapping relation in the water environment-camera parameter database, and the imaging quality of underwater shooting is improved.
In some embodiments, the water environment-camera parameter database includes a plurality of algorithms, such as an exposure compensation algorithm. The aquatic environment sensor 10 can output a current sensor signal that includes a current ambient light signal. The current ambient light signal may be analyzed to obtain current ambient light information, the current ambient light information and an exposure compensation algorithm in the water environment-camera parameter database are then utilized to calculate exposure parameters, and finally the exposure parameters are applied to the camera system 20. Therefore, if the current ambient light is dark, appropriate exposure parameters can be obtained according to the current ambient light information and the exposure compensation algorithm, and after the camera system 20 is adjusted by applying the exposure parameters, a shot picture can be brighter, the imaging quality of underwater shooting is improved, and the visual effect is ensured.
Referring to fig. 4, in some embodiments, the aquatic environment sensor 10 includes a temperature sensor, an atmospheric pressure sensor, and an ambient light sensor. The processor 30 may determine whether the mobile terminal 100 is switched to the underwater mode using the water environment-camera parameter database in combination with the signals generated by the three sensors. The water environment-camera parameter database can store data sets in all modes to judge the current working mode, can also store data sets of the underwater mode, and judges whether the underwater mode is the underwater mode or not by combining signals generated by the three sensors. Judging that the mobile terminal 100 is not in water, the mobile terminal 100 can be kept in a land mode; if it is determined that the mobile terminal 100 is underwater, the mobile terminal 100 may be switched to the underwater mode. When the mobile terminal 100 is switched to the underwater mode, the camera system 20 may automatically turn on the photographing function, and the image signal processing unit of the camera system 20 may prepare according to signals output by the three sensors. Therefore, underwater shooting can be simply, conveniently and quickly realized, the optimal camera parameters can be output according to signals output by the three sensors, and the imaging quality of underwater shooting is improved.
It is noted that, in some embodiments, the mobile terminal 100 may include not only a land mode and a underwater mode, but also a day mode, a night mode, a sport mode, and the like, which are not limited herein. The mobile terminal 100 may be used for photographing in various modes. Therefore, the working mode of the mobile terminal 100 can be switched, and the interest of shooting can be improved by shooting in different modes, so that the user experience is improved.
Referring to fig. 5, in some embodiments, the aquatic environment sensor 10 includes an ambient light sensor and a gyroscope, the camera parameters include focus parameters, and step 02 includes:
021: acquiring a current ambient light value by using an ambient light sensor;
022: acquiring a current angular velocity by using a gyroscope to obtain a jitter value;
023: and searching focusing parameters corresponding to the current ambient light value and the jitter value in a water environment-camera parameter database.
In some embodiments, the control method of the embodiments of the present application may be implemented by the mobile terminal 100 of the embodiments of the present application. The mobile terminal 100 includes a water environment sensor 10, the water environment sensor 10 includes an ambient light sensor and a gyroscope, and the camera parameters include focusing parameters. Step 021, step 022, and step 023 may all be implemented by processor 30. That is, the processor 30 is configured to: acquiring a current ambient light value by using an ambient light sensor; acquiring a current angular velocity by using a gyroscope to obtain a jitter value; and searching focusing parameters corresponding to the current ambient light value and the jitter value in a water environment-camera parameter database.
In the related art, focusing is difficult in underwater photography due to insufficient underwater light intensity, movement of a user relative to water, and flow of water current itself. The current ambient light value can be obtained through the ambient light sensor, and the current angular velocity is obtained through the gyroscope so as to obtain the jitter value. The water environment-camera parameter database comprises a mapping relation between a calibration environment light value and a calibration jitter value and a calibration focusing parameter. Therefore, the calibration focusing parameter can be determined by searching the corresponding calibration ambient light value by using the current ambient light value, searching the corresponding calibration jitter value by using the jitter value, and then using the searched calibration ambient light value and the calibration jitter value. The calibrated focus parameters are applied to the camera system 20 as focus parameters. Therefore, accurate focusing can be realized during underwater shooting, and the imaging quality of underwater shooting is improved.
In some implementations, a focus learning model trained in advance can be included within the environment-touch database. The ambient light values may include water flow refraction light values and ambient light and darkness values. The focusing learning model trained in advance can be obtained by training three values, namely a water flow refraction light value, an ambient light and darkness value and a shaking value in advance through a training set, and the focusing parameters corresponding to the current ambient light value and the shaking value can be calculated through the focusing learning model. Therefore, accurate focusing can be realized during underwater shooting, and the imaging quality of underwater shooting is improved.
Referring to fig. 6, in one embodiment, the user holds the mobile terminal 100 into water, the mobile terminal 100 can be switched to the underwater mode, and the camera system 20 is turned on. The user can preset underwater shooting shortcut key, and the preset underwater shooting shortcut key comprises a user-defined image/video switching key and a quick shooting key, so that the user can conveniently shoot underwater. After the system 20 is turned on, camera parameters, including focusing parameters, may be generated based on information from the ambient light sensor, the barometric sensor, and the gyroscope. The camera parameters are then applied to the camera system 20, for example: the flash of the camera system 20 is turned on according to the camera parameters, the image signal processing unit is controlled to process the picture according to the camera parameters, the OIS optical anti-shake is turned on according to the camera parameters, the exposure compensation is turned on according to the camera parameters, the auto-focus is realized according to the camera parameters, and the like, which are not limited herein.
Referring to fig. 7, in some embodiments, the aquatic environment sensor 10 includes an ambient light sensor, the camera parameters include filter parameters, and step 02 includes:
024: acquiring a current color value and a transmittance value by using an ambient light sensor;
025: and searching filter parameters corresponding to the current color value and the light transmittance value in a water environment-camera parameter database.
In some embodiments, the control method of the embodiments of the present application may be implemented by the mobile terminal 100 of the embodiments of the present application. The mobile terminal 100 includes a water environment sensor 10, the water environment sensor 10 includes an ambient light sensor, and the camera parameters include filter parameters. Both steps 024 and 025 may be implemented by processor 30. That is, the processor 30 is configured to: acquiring a current color value and a transmittance value by using an ambient light sensor; and searching filter parameters corresponding to the current color value and the light transmittance value in a water environment-camera parameter database.
Particularly, in underwater shooting, as the underwater depth increases, the red-orange-yellow spectrum in sunlight is absorbed by water, which can cause poor color and even blurred picture of the picture shot by the user. Therefore, filter parameters conforming to the current shooting environment are generated, and the filter parameters are applied to the camera system 20, so that the real color of the picture can be restored, the picture is clearer, and the imaging quality is improved. The ambient light sensor may obtain a current color value and a transmittance value. The mapping relation between the calibration color value and the calibration transmittance value and the calibration filter parameter is included in the water environment-camera parameter database, so that the corresponding calibration color value can be searched by using the current color value, the corresponding calibration transmittance value can be searched by using the transmittance value, and the calibration filter parameter can be determined by using the searched calibration color value and calibration transmittance value. The calibration filter parameters are applied to the camera system 20 as filter parameters. Therefore, the real color of the picture can be restored during underwater shooting, so that the picture is clearer, and the imaging quality is improved.
Referring to fig. 6 again, in some embodiments, since different regions have different water qualities, which may lead to different water permeability, when shooting underwater with poor permeability, filter parameters may be generated, and the filter parameters may be used to perform thinning and atomizing processing on the shot image to make the image clearer. And generating filter parameters to carry out filter processing on the shot picture so as to optimize the shot picture, wherein the filter processing comprises but is not limited to hue contrast processing, picture brightness contrast processing, depth of field processing and the like. When the user can shoot underwater, the camera system 20 is turned on to use the filter for processing, and the mobile terminal 100 can implement the filter for processing the picture when shooting in real time; or the photographed pixel points can be saved when the user photographs, and the filter is selected for processing at the later stage, which is not limited here.
Referring to fig. 8, in some embodiments, the mobile terminal 100 includes a touch screen, and the control method further includes:
041: acquiring a current touch signal in an underwater mode;
042: searching a touch setting parameter corresponding to the current touch signal in a water environment-touch database;
043: applying touch setting parameters to the touch screen.
In some embodiments, the control method of the embodiments of the present application may be implemented by the mobile terminal 100 of the embodiments of the present application. The mobile terminal 100 includes a touch screen. Step 041, step 042 and step 043 may all be implemented by processor 30. That is, the processor 30 is configured to: acquiring a current touch signal in an underwater mode; searching a touch setting parameter corresponding to the current touch signal in a water environment-touch database; applying touch setting parameters to the touch screen.
In one embodiment, the touch screen comprises a capacitive screen. When a user touches the capacitive screen, a touched area of the capacitive screen generates a touch signal, and the touch signal comprises a capacitance value signal. When the capacitive screen is used in the land mode, the generated capacitance signal is usually within the capacitance signal range, and the corresponding touch operation can be realized within the capacitance signal range. However, when the user uses the mobile terminal 100 underwater, the capacitive screen may recognize a pressure change caused by water flow as a touch signal, so that when the user touches the capacitive screen with a hand, the user is likely to have insensitivity or even touch failure. The mobile terminal 100 according to the embodiment of the present application can be switched to the underwater mode. In the underwater mode, a user touches the touch screen to generate a current touch signal, corresponding touch setting parameters can be searched in a water environment-touch database according to the current touch signal, and finally the touch setting parameters are applied to the touch screen, so that the effect of identifying the underwater touch screen of the user can be achieved, the touch insensitivity is prevented, and the condition of no response to touch is avoided.
Specifically, the water environment-touch database may include a pre-trained deep learning model, and the pre-trained deep learning model may be trained by samples of three basic scenes, namely, a pre-terrestrial mode touch signal, a pre-pure water flow pressure change signal, and a pre-underwater mode touch signal. Therefore, the current touch signal and the deep learning model trained in advance can be used for obtaining touch setting parameters, the touch setting parameters are applied to the touch screen, the effect of underwater touch control of the touch screen is guaranteed, the mobile terminal 100 can be normally used when a user is underwater, and the user can use the camera system 20 to shoot in a touch control mode.
Referring again to fig. 6, in some embodiments, when the user holds the mobile terminal 100 in water, the mobile terminal 100 may automatically switch to the underwater mode. A user can acquire a current touch signal by touching any position of a touch screen of the mobile terminal, generates touch setting parameters and applies the touch setting parameters to the touch screen, so that the touch screen enters an underwater touch mode. Therefore, the camera system 20 can be started in a touch manner, so that the use requirements of the user are met, and the use experience of the user is improved.
Referring to fig. 9, in some embodiments, the aquatic environment sensor 10 includes a temperature sensor, an air pressure sensor and an ambient light sensor, and the control method includes:
051: acquiring a current temperature value by using a temperature sensor;
052: acquiring a current air pressure value by using an air pressure sensor;
053: acquiring a current ambient light value by using an ambient light sensor;
054: it is determined that the mobile terminal 100 operates in the underwater mode when the current temperature value falls within the predetermined temperature range, when the current atmospheric pressure value falls within the predetermined atmospheric pressure range, and when the current ambient light value falls within the predetermined ambient light range.
In some embodiments, the control method of the embodiments of the present application may be implemented by the mobile terminal 100 of the embodiments of the present application. The mobile terminal 100 includes a water environment sensor 10, and the water environment sensor 10 includes a temperature sensor, an air pressure sensor, and an ambient light sensor. Step 051, step 052, step 053 and step 054 may all be implemented by processor 30. That is, the processor 30 is configured to: acquiring a current temperature value by using a temperature sensor; acquiring a current air pressure value by using an air pressure sensor; acquiring a current ambient light value by using an ambient light sensor; it is determined that the mobile terminal 100 is operated in the underwater mode when the current temperature value falls within the predetermined temperature range, when the current air pressure value falls within the predetermined air pressure range, and when the current ambient light value falls within the predetermined ambient light range.
Referring again to fig. 4, in some embodiments, the mobile terminal 100 includes a predetermined database. The current temperature value, the current air pressure value and the current ambient light value can be obtained, and whether the mobile terminal 100 works in the underwater mode can be judged by utilizing the pre-stored data in the preset database. A data set of underwater patterns is stored in a predetermined database, the data set including a predetermined temperature range, a predetermined pressure range, and a predetermined ambient light range. The predetermined temperature range, the predetermined atmospheric pressure range, and the predetermined ambient light range may be data obtained through a plurality of experimental analyses, and it may be determined that the mobile terminal 100 operates in the underwater mode when the current temperature value falls within the predetermined temperature range, the current atmospheric pressure value falls within the predetermined atmospheric pressure range, and the current ambient light value falls within the predetermined ambient light range.
The current temperature value is obtained by a temperature sensor, which in one embodiment is typically obtained on land higher than under water during the summer. For example: taking seawater as an example, the temperature value obtained on land in summer may be 25 ℃, and the temperature value obtained underwater may be 19 ℃. In winter, the temperature values obtained are generally lower on land than under water. For example: taking seawater as an example, the temperature value obtained on land in winter can be-10 ℃, at the moment, the seawater is in the state of ice-water mixture, and the temperature value obtained underwater can be 0 ℃. Therefore, when the land mode is converted into the underwater mode, the temperature value acquired by the temperature sensor changes. It is worth mentioning that the temperature value at shallow water is different from the temperature value at deep water in the same water area.
The current barometric pressure value is obtained by a barometric pressure sensor. The underwater air pressure value is different from the land air pressure value, and when the land mode is converted into the underwater mode, the air pressure value acquired by the air pressure sensor changes. It is worth mentioning that the air pressure value at deep water and the air pressure value at shallow water are different in the same water area, so that the water depth can be detected by the air pressure sensor.
The current ambient light value is obtained by an ambient light sensor. Water is a transparent medium, but the ambient light is absorbed and weakened continuously when the ambient light propagates in the water, so that the underwater ambient light value is different from the land ambient light value. And the ambient light values are different due to different water depths; the clarity of the water varies, as does the ambient light value.
In this way, it may be determined that the mobile terminal 100 operates in the underwater mode by combining the current temperature value, the current air pressure value, and the current ambient light value.
When it is determined that the mobile terminal 100 is operating in the underwater mode, the current underwater condition may be preliminarily determined by acquiring the current air pressure value using the air pressure sensor and the current ambient light value using the ambient light sensor. For example: the air pressure values at the water depth of 1 meter are different from the air pressure values at the water depth of 10 meters, so that the water depth can be accurately judged according to the current air pressure value; the clarity degree of the water can be judged by combining the depth of the water and the current ambient light value. Therefore, the camera parameters can be generated conveniently, the imaging quality is ensured, and the user experience is improved.
