[0028] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present application.

[0029] A shooting control method provided in the embodiments of the present application can be applied to a terminal device with a shooting function, and the terminal device can be implemented in various forms. For example, the terminal device described in the embodiments of the present application may include a mobile terminal such as a mobile phone, a camera, a tablet computer, a laptop computer, a PDA, a portable media player (PMP), a navigation device, a wearable device, etc.

[0030] The terminal device may include: an RF (Radio Frequency) device, a WiFi module, an audio input device, an audio output device, a camera device, multiple sensors, a display unit, a user input unit, an interface unit, a memory, a processor, a power supply and other components.

[0031] The camera device is used to receive image signals. The camera device may include a camera, or may include a camera and its corresponding graphics processing unit (GPU), which processes image data of a static picture or video obtained by the camera in a video capture mode or an image capture mode. The processed image frame may be displayed on a display unit.

[0032] Sensors include: proximity sensor, distance sensor, gyroscope sensor, magnetometer sensor, acceleration sensor, color temperature sensor, temperature sensor, humidity sensor, light sensor, air pressure sensor, Hall sensor, etc.

[0033] Color temperature sensor: The main function is to measure the color temperature of the light emitted by an object, that is, the degree to which the white light of the light source is cold or hot. It collects spectral features, uses optical filtering technology to separate the spectrum, and then detects and calculates the spectrum to finally derive the luminous color temperature of the object.

[0034] The proximity sensor determines the distance between an object and a mobile terminal by emitting infrared or ultrasonic waves and measuring the strength or time delay of the reflected signal.

[0035] Distance sensor, used to sense the distance between it and an object.

[0036] The gyroscope sensor is used to measure the angular velocity of the mobile terminal around three axes, while the accelerometer can measure the acceleration of the mobile terminal on three axes. By analyzing and processing these data, the movement information such as the mobile phone's moving direction, speed, acceleration, etc. can be determined. In addition, the magnetometer can also provide additional magnetic field information to help calibrate and correct the posture and direction of the mobile terminal. These sensors work together to provide key information such as the posture, angular velocity, acceleration, etc. of the mobile phone in real time.

[0037] Based on the above-mentioned mobile terminal hardware structure, a shooting control method provided in an embodiment of the present application is specifically a sensor-based shooting control method. This method provides a new control method for the camera device, so that the camera device is suitable for the control needs of more environments, for example, underwater, humid, high temperature and extreme cold environments. In these environments, the sensor-based shooting control function realizes contactless shooting control, which can reduce the risk of water ingress and control failure compared to physical button control and virtual button control.

[0038] Figure 1 Schematic diagram of the first process of the shooting control method in the embodiment of the present application. Figure 1 As shown, the method may specifically include:

[0039] Step 101: starting a shooting control function based on one or more sensors for a camera device, where the one or more sensors are used to implement contactless shooting control for the camera device;

[0040] The shooting control function based on one or more sensors can be understood as a method of performing control operations on the camera device by sensing the user's operation behavior through the sensor. The user operation behavior is a contactless operation behavior, that is, the user can achieve shooting control without direct contact with the sensor, which is different from the traditional contact operation behavior on virtual buttons or physical buttons.

[0041] In some embodiments, the one or more sensors include but are not limited to at least one of the following: a proximity sensor, a gyroscope, and a light sensor (also called a light sensor). Different sensors correspond to different shooting controls, or different data features of the same sensor correspond to different shooting controls.

[0042] In some embodiments, when the method is applied to a preset scene, the method further includes: when it is detected that the current environment is a preset environment, starting a shooting control function based on one or more sensors.

[0043] In some embodiments, when a user-initiated operation is detected, a shooting control function based on one or more sensors is initiated.

[0044] In some embodiments, when the current environment is detected as a preset environment and a user-initiated operation is detected, a shooting control function based on one or more sensors is started. For example, when the current environment is detected as a preset environment, it is determined whether a user-initiated operation is detected; if a user-initiated operation is detected, the shooting control function based on one or more sensors is started; if no user-initiated operation is detected, the current shooting control function based on a virtual key or a physical key is maintained.

[0045] In some embodiments, at least one of the following is further included: performing environmental perception based on sensor data collected by the first sensor to determine whether the current environment is a preset environment; performing environmental perception based on image data collected by the camera device to determine whether the current environment is a preset environment. In other words, environmental perception is performed by the first sensor and / or the camera device to determine whether the current environment is a preset environment.

[0046] The first sensor includes one or more sensors for sensing one or more environmental information. Exemplarily, the first sensor includes but is not limited to one or more of a color temperature sensor, a temperature sensor, a humidity sensor, and an air pressure sensor. The color temperature sensor is used to sense the color temperature of the ambient light, the temperature sensor is used to sense the ambient temperature, the humidity sensor is used to sense the ambient humidity, and the air pressure sensor is used to sense the atmospheric pressure. Environmental sensing through multiple sensors can improve the detection accuracy.

[0047] In some embodiments, when the first sensor includes a color temperature sensor, environmental perception is performed based on sensor data collected by the first sensor to determine whether the current environment is a preset environment, including: when the brightness ratio of the green channel and / or the blue channel of the current environment is within a preset value range, determining that the current environment is the preset environment, and the preset value range is the value range of the brightness ratio of the green channel and / or the blue channel of the preset environment; when the brightness ratio of the green channel and / or the blue channel of the current environment is outside the preset value range, determining that the current environment is not the preset environment.

[0048] If the value range of the brightness ratio of the green channel and / or blue channel of the preset environment is different from that of other environments, the preset environment can be accurately identified by color temperature detection through the color temperature sensor. If the value range of the brightness ratio of the green channel and / or blue channel of the preset environment is not significantly different from that of other environments, the preset environment and other environments can also be distinguished by combining or using the detection results of other sensors.

[0049] Exemplarily, environmental perception is performed based on image data captured by a camera device to determine whether the current environment is a preset environment, including: identifying the preset environment based on one or more frames of image data captured by the camera device; if the image data contains preset environment features, determining that the current environment is the preset environment; otherwise, determining that the current environment is not the preset environment.

[0050] In some embodiments, the preset environment is an underwater environment. The method for underwater environment perception based on a color temperature sensor may include: when the brightness ratio of the green channel and / or the blue channel is greater than a first threshold, determining that the current environment is an underwater environment. Further, when the brightness ratio of the green channel and / or the blue channel is less than or equal to the first threshold, determining that the current environment is not an underwater environment. The value of the first threshold may be greater than or equal to 70%, for example, the value of the first threshold is 80%.

[0051] The method for underwater environment perception based on image data collected by a camera device may include: identifying the underwater environment based on one or more frames of image data collected by the camera device; if the image data contains underwater environment features, determining that the current environment is an underwater environment; otherwise, determining that the current environment is not an underwater environment.

[0052] When applied to underwater scenes, this method can be understood as a sensor-based underwater shooting control method. According to the control requirements of the underwater environment, the shooting control function based on one or more sensors is started to realize contactless underwater shooting control. Compared with physical button control, it can reduce the risk of water ingress to the equipment, and compared with touch screen control, it can improve the operation success rate.

[0053] In some embodiments, the sensor data collected by the first sensor and / or the image data collected by the camera device are input into a trained artificial intelligence model for environmental perception to determine whether the current environment is a preset environment.

[0054] In some embodiments, the method also includes: when performing environmental perception based on sensor data collected by the first sensor to determine that the current environment is a preset environment, starting a capture function of the camera device; acquiring image data collected by the camera device; and performing environmental perception based on the image data collected by the camera device to determine whether the current environment is a preset environment.

[0055] First, the current environment is monitored in real time through the first sensor. If the current environment enters the preset environment, the capture function of the camera device is activated to further refine whether the terminal device is in the preset environment. If the current environment is confirmed to be the preset environment, the shooting control function based on one or more sensors is activated. Otherwise, it is not activated and the current shooting control function based on the virtual button or physical button is maintained.

[0056] In a preset environment, the camera device is controlled to enter a preset shooting mode, and non-contact shooting control of the camera device is implemented based on one or more sensors in the preset shooting mode. In some embodiments, the preset shooting mode may also include an image processing method for the preset environment. Since there are significant differences in light conditions, temperature, humidity, and clarity between the preset environment and the normal environment, these differences require different methods for image processing. These differences are effectively resolved by color correction, brightness adjustment, clarity enhancement, etc., and the quality of the preset captured image is improved.

[0057] Step 102: Acquire sensor data collected by one or more sensors;

[0058] Step 103: Determine a target control instruction of the camera device based on the sensor data;

[0059] The user operation behavior is determined by processing and analyzing the sensor data, thereby determining the target control instruction corresponding to the user operation behavior.

[0060] In some embodiments, target control instructions are determined based on sensor data input into a trained artificial intelligence model.

[0061] In some embodiments, determining a target control instruction of a camera device based on sensor data includes: determining a target control condition satisfied by the sensor data from one or more control conditions based on the sensor data; and determining a target control instruction corresponding to the target control condition based on a correspondence between one or more control conditions and control instructions.

[0062] In some embodiments, the control instruction includes but is not limited to at least one of the following: a start instruction, a camera device switching instruction, a photo / video recording instruction, an image zoom instruction, and an exit instruction.

[0063] In some embodiments, if the second data collected by the second sensor meets the start condition, that is, the target control condition is the start condition, the target control instruction is determined to be the start instruction, and the start instruction corresponds to the start control of the camera device; or, if the third data collected by the third sensor meets the exit condition, that is, the target control condition is the exit condition, the target control instruction is determined to be the exit instruction, and the exit instruction corresponds to the exit control of the camera device.

[0064] The second sensor and the third sensor can be different sensors, respectively realizing starting shooting and exiting shooting. In some embodiments, the second sensor is a proximity sensor, and the third sensor is a light sensor. For example, touching (or within a certain distance) the proximity sensor starts the camera device, and blocking the light sensor turns off the camera device.

[0065] The second sensor and the third sensor may also be the same sensor, and different operations on the same sensor may be used to respectively realize the control operations of starting shooting and exiting shooting. In some embodiments, the second sensor and the third sensor are both proximity sensors, for example, touching the proximity sensor starts the camera device, and touching the proximity sensor again turns off the camera device. In some embodiments, the second sensor and the third sensor are both light sensors, for example, blocking the light sensor starts the camera device, and blocking the light sensor again turns off the camera device.

[0066] In some embodiments, if the fourth data collected by the fourth sensor meets the switching condition, that is, the target control condition is the switching condition, the target control instruction is determined to be a camera switching instruction. The camera switching instruction corresponds to switching the current working camera to the target camera. For example, for a mobile phone, the switching instruction corresponds to the switching control of the front camera and the rear camera.

[0067] In some embodiments, the control instructions also include other control instructions for the camera device, such as shooting mode selection instructions, or shooting parameter selection instructions, etc. For example, the shooting mode includes photo mode, video mode, portrait mode, night scene mode, live mode and other mode selections, and the shooting parameters include resolution, magnification, exposure and other parameters.

[0068] In some embodiments, the fourth sensor includes a proximity sensor. For example, after starting the camera device, the camera device is switched by touching (or within a certain distance) the proximity sensor. Different shooting control operations can be achieved by controlling the contact time of the proximity sensor. For another example, the camera device is switched by touching the proximity sensor for a short time (such as within 1 second or 2 seconds).

[0069] In some embodiments, the fourth sensor also includes a gyroscope. For example, after the camera device is started, the gyroscope detects that the camera device (which can also be understood as a terminal device including the camera device) shakes a certain angle, thereby realizing the selection of shooting mode or shooting parameters.

[0070] In some embodiments, the fourth sensor also includes multiple sensors such as gyroscopes, accelerometers, and light sensors. These sensors detect the motion information of the camera device, and based on the correspondence between the motion information and the selection instructions, the camera device is switched, or the shooting mode is selected, or the shooting parameter is selected.

[0071] In some embodiments, if the fifth data collected by the fifth sensor meets the shooting condition, that is, the target control condition is the shooting condition, the target control instruction is determined to be a photo / video recording instruction, and the photo / video recording instruction is used to control the camera device to perform a photo / video recording operation.

[0072] In some embodiments, the fifth sensor includes one or more sensors for collecting motion information; the motion information may specifically include: acceleration information, angular velocity information, posture information, motion trajectory, etc. The shooting conditions include restriction conditions of the motion information.

[0073] For example, the fifth sensor includes a gyroscope. After the camera device is started, when the gyroscope detects that the fluctuation angle of the camera device is less than 0.1° and lasts for more than or equal to 3 seconds, 5 seconds, or 10 seconds, it will directly trigger the photo or video recording process.

[0074] In some embodiments, if the sixth data collected by the sixth sensor meets the zoom condition, that is, the target control condition is the zoom condition, the target control condition is determined to be an image zoom instruction, and the image zoom instruction includes zoom control of the preview image or the captured image.

[0075] That is to say, after starting the camera device, the sixth data collected by the sixth sensor is used to control the zoom of the preview image or the captured image. In practical applications, different operations on the same sensor can be used to respectively zoom in or out the image, which has the characteristics of simple operation. Different sensors can also be used to respectively zoom in or out the image.

[0076] In some embodiments, the sixth sensor includes: a proximity sensor and / or a light sensor. For example, firstly approach the proximity sensor continuously (for example, for more than 2 seconds or 3 seconds) or touch the proximity sensor twice in succession to achieve image zooming, then approach the proximity sensor continuously (for example, for more than 2 seconds or 3 seconds) or touch the proximity sensor twice in succession again to achieve image zooming. For another example, approach the proximity sensor continuously or touch the proximity sensor twice in succession to achieve image zooming, then approach the proximity sensor continuously or touch the proximity sensor twice in succession again to achieve image zooming.

[0077] In some embodiments, the one or more sensors further include at least one of the following: a distance sensor, a gravity sensor, a magnetometer sensor, an acceleration sensor, a Hall sensor, etc.

[0078] In some embodiments, the control condition may include at least one of the following:

[0079] The first control condition is that the proximity sensor detects that an object is approaching and the approaching time is greater than a first time threshold;

[0080] The second control condition is that the gyroscope detects that the camera device is in a stable state and the duration is greater than a second time threshold;

[0081] The third control condition is that the proximity sensor detects that an object is approaching, and the approaching time is greater than a third time threshold, and the first time threshold and the third time threshold are different;

[0082] The fourth control condition is that the light sensor detects that there is an object blocking the light, and the blocking time is greater than a fourth time threshold.

[0083] In some embodiments, the corresponding relationship may include at least one of the following:

[0084] Before the camera device is started, the first control condition corresponds to a start instruction;

[0085] After the camera device is started, the first control condition corresponds to a camera device switching instruction;

[0086] The second control condition corresponds to the photo / video recording instruction;

[0087] The third control condition corresponds to an image scaling instruction;

[0088] The fourth control condition corresponds to an exit instruction.

[0089] In some embodiments, the first time threshold is less than the third time threshold. For example, a finger briefly approaches the proximity sensor to start the camera device or switch the camera device, and the finger continues to approach the proximity sensor to zoom in and out the image.

[0090] In some embodiments, the control condition may further include at least one of the following:

[0091] The fifth control condition is that the gyroscope detects that the camera device is in a preset motion state and the duration is greater than a fifth time threshold;

[0092] The sixth control condition is that the light sensor detects that there is an object blocking the light, and the blocking time is greater than the sixth time threshold, and the fourth time threshold is different from the sixth time threshold.

[0093] Step 104: In response to the target control instruction, execute corresponding shooting control on the camera device.

[0094] The embodiments of the present application provide a new control method for the camera device, so that the camera device is suitable for the control requirements of more environments, for example, extreme environments such as underwater, humid, high temperature and extremely cold. In these environments, the sensor-based shooting control function realizes contactless shooting control, which can reduce the risk of water ingress and control failure of the equipment compared to physical button control and virtual button control.

[0095] Let's take the preset environment as an underwater scene for further explanation. Figure 2 : is a second flow chart of the shooting control method in the embodiment of the present application, such as Figure 2 As shown, the method may specifically include:

[0096] Step 201: Underwater environment detection, starting a sensor-based shooting control function;

[0097] Step 202: Proximity sensor detection;

[0098] Step 203: Start the camera;

[0099] Step 204: proximity sensor detection;

[0100] Step 205: Camera selection;

[0101] Step 206: Proximity sensor detection;

[0102] Step 207: Shooting mode selection;

[0103] Step 208: gyroscope detection;

[0104] Step 209: taking photos or videos;

[0105] Step 210: light sensor detection;

[0106] Step 211: Turn off the camera;

[0107] Step 212: Exit the sensor-based shooting control function.

[0108] It should be noted that if the detection result of the proximity sensor determines that the current camera does not need to be changed, step 205 can be skipped and step 206 can be executed.

[0109] It should be noted that if the detection result of the proximity sensor determines that the current shooting mode does not need to be changed, step 207 can be skipped and step 208 can be executed.

[0110] It should be noted that step 208 may be directly executed after step 205, that is, taking a photo or recording a video directly after the camera is selected.

[0111] After starting the sensor-based shooting control function, all related controls do not require hardware clicks or button operations. Instead, shooting control is performed based on proximity sensors, gyroscope sensors, light sensors, etc., to achieve shooting controls such as starting and shutting down underwater shooting, switching cameras, taking photos / recording videos, and selecting shooting modes (video, photo, etc.).

[0112] like Figure 3 As shown, the specific process of the method for starting and stopping underwater shooting may include:

[0113] Step 301: Detect the color temperature of the current environment;

[0114] Step 302: determine whether the brightness ratio of the green channel and / or the blue channel of the current environment is greater than 80%; if yes, execute step 303; if no, return to step 301;

[0115] Step 303: Start the snapshot function to obtain image data collected by the camera;

[0116] Step 304: perform image detection on the image data to determine whether the current environment is an underwater environment; if yes, execute step 305; if no, return to step 301;

[0117] Step 305: Start the sensor-based shooting control function;

[0118] Step 306: briefly approach the location of the proximity sensor;

[0119] Step 307: Start the camera;

[0120] Step 308: temporarily blocking the light sensor;

[0121] Step 309: Outputting exit prompt information;

[0122] Exit prompt information includes: text, image, voice, prompt light, vibration and other prompt information.

[0123] In some embodiments, the exit prompt information includes light blocking prompt information, which is used to remind the user that light blocking will trigger a camera shutdown operation.

[0124] In some embodiments, the exit prompt information includes an exit countdown, and the camera is turned off when the countdown ends.

[0125] In some embodiments, the exit prompt information includes light blocking prompt information and an exit countdown.

[0126] Step 310: Turn off the camera.

[0127] The camera startup and shutdown process first uses the color temperature sensor to detect the color temperature of the current environment. According to the light characteristics in the water, green or blue accounts for a larger proportion. The color proportion is used to determine whether the terminal device (such as a mobile phone, smart watch, etc.) is in an underwater environment. Then start the snapshot to further refine and confirm whether the terminal device is in an underwater environment. If the underwater environment is confirmed, touch the location of the proximity sensor to start the camera. Blocking the light sensor prompts the countdown to exit underwater shooting, and then turns off the camera. The shooting control method provided in the embodiment of the present application can achieve contactless underwater shooting control, with stronger overall waterproofness and experience, support for underwater operation, and more convenient.

[0128] When starting the camera for underwater shooting, it also supports camera switching, image zooming, mode selection, parameter selection, and starting photo or video recording and other shooting controls.

[0129] like Figure 4As shown, during underwater shooting, an optional implementation process of the camera switching method includes:

[0130] Step 401: Start the camera;

[0131] Step 402: The proximity sensor detects whether there is an object approaching; if yes, execute step 402; if not, do not switch cameras, and use the current camera to take pictures or record videos.

[0132] Step 403: Start the camera;

[0133] Step 404: confirming the shooting mode and / or shooting parameters;

[0134] Step 405: Execute the process of taking a photo or recording a video.

[0135] When the camera is started for underwater shooting, if the proximity sensor detects an object approaching (for example, within 3 cm), the camera will be switched to achieve switching between different cameras.

[0136] like Figure 5 As shown, during underwater shooting, an optional implementation process of triggering a method for taking a photo or recording a video includes:

[0137] Step 501: Start the camera;

[0138] Step 502: The gyroscope detects whether the fluctuation angle of the mobile phone is less than 0.1°; if yes, execute step 503; if no, continue to detect the fluctuation of the mobile phone;

[0139] Step 503: Trigger taking a photo or recording a video.

[0140] like Figure 6 As shown, an optional implementation process of the image zoom control method includes:

[0141] Step 601: Preview an image or view a cached image;

[0142] Step 602: The proximity sensor detects whether an object continues to approach; if so, execute step 603;

[0143] Step 603: image enlargement;

[0144] For example, zoom in on a region of interest or zoom in on the center of an image.

[0145] Step 604: The proximity sensor detects whether an object continues to approach; if so, execute step 605;

[0146] Step 605: Image reduction.

[0147] For example, reducing an enlarged image to its original image size.

[0148] The embodiment of the present application uses a proximity sensor to detect whether an object (such as a finger) is continuously approaching to perform zoom control, and has high control sensitivity and high control efficiency.

[0149] The shooting control method provided in the embodiment of the present application has the following advantages for underwater shooting control:

[0150] 1) Take photos or videos without any sensor triggering through the gyroscope, with better waterproof performance;

[0151] 2) Through the color temperature sensor and the camera's capture function, the underwater environment can be automatically identified, and the camera can be started for underwater shooting without contact through proximity sensor detection. Its self-powered control performance is better and the operation is more convenient;

[0152] 3) The proximity time of the proximity sensor is used to trigger the camera module switching and image zooming to improve the underwater shooting control performance.

[0153] To implement the method of the embodiment of the present application, based on the same inventive concept, the embodiment of the present application also provides a shooting control device, such as Figure 7 As shown, the shooting control device 70 includes:

[0154] A control unit 701 is used to start a shooting control function of one or more sensors, where the one or more sensors are used to perform contactless shooting control on the camera device;

[0155] An acquisition unit 702, configured to acquire sensor data collected by one or more sensors;
