Description

Control chip management method, electronic device, and computer-readable storage medium

Technical Field

The present application relates to the field of electronic technology, and in particular, to a control chip management method, an electronic device, and a computer readable storage medium.

Background

In order to make the shooting functions of the terminal equipment increasingly richer and improve the shooting effect, the functions and scenes supported by the camera of the terminal equipment are also increasingly more and more.

In some scenarios, for example, in the case of supporting functions such as spaced gestures and face detection, it is often necessary that the front camera be always on to ensure that external gestures or faces can be recognized at any time. The front-end camera is often also configured with an auto-focus integrated circuit (AF IC) to achieve an auto-focusing function of the front-end camera, so as to improve the shooting effect of the front-end camera. Specifically, the terminal device needs to supply power to the AF IC of the front camera in a state that the front camera is normally open, and drives the motor of the front camera through the AF IC, so as to realize automatic focusing. In the current terminal device, an AF IC of the front camera is powered by a power management unit (power management unit, PMU). For example, the power port of the AF IC of the front-end camera is connected with the power port of a low dropout linear regulator (low dropout regulator, LDO) of the PUM to supply power. Typically, the cameras on the terminal device include more than one front camera and one or more rear cameras. The rear camera can also realize automatic focusing under the control of the corresponding AF IC. Some rear cameras are also often equipped with an optical image stabilizer (Optical Image Stabilizer, OIS) to prevent shake. In the current terminal equipment, in order to save cost, the same path of LDO power supply is generally used for supplying power to devices such as AF IC, OIS and the like of all cameras.

For terminal equipment powered by the same power supply for devices such as AF ICs and OIS of a plurality of cameras, the AF ICs and OIS of the rear cameras can be powered together when the AF ICs of the front cameras are powered. The AF ICs, OIS, etc. of the rear cameras do not need to use devices, and after power is applied, a certain substrate power consumption is generated, which results in power consumption waste.

Disclosure of Invention

The application provides a control chip management method, a control chip management device, electronic equipment, a computer readable storage medium and a computer program product, which can save power consumption.

In a first aspect, a method for managing a control chip is provided, the method is applied to an electronic device, the electronic device at least includes a target camera and other cameras, the target camera and other cameras are different, and control chips of the target camera and other cameras are all connected with the same power port, and the method includes: acquiring a shooting instruction, wherein the shooting instruction is used for indicating a target camera to shoot; and responding to the shooting instruction, sending a dormancy instruction to the control chips of the other cameras, wherein the dormancy instruction is used for indicating the control chips of the other cameras to enter a dormancy state.

In general, an electronic device is provided with a plurality of cameras, a front camera is disposed on one side of a screen, and a rear camera is disposed on one side of a rear cover. In general, the front camera may be used for detecting a face, a gesture, etc., and needs to be kept in a normally open state. The rear cameras typically include a main camera and may also include cameras that support other photographing functions, such as wide angle cameras that photograph a wide range of scenes, tele cameras that photograph a long view, and so on. Sometimes, the rear camera may also include a macro camera that photographs close-up objects. The cameras are provided with corresponding automatic focusing chips for automatic focusing, and some cameras are also provided with OIS for anti-shake.

To save cost, the same LDO power supply of PMU is typically used to power devices such as AF IC and OIS of all cameras.

For electronic equipment powered by the same power supply for devices such as AF ICs and OIS of a plurality of cameras, the AF ICs and OIS of the rear cameras can be powered together when the AF ICs of the front cameras are required to be powered (simply powered up). The devices which are not needed to be used in the current state such as an AF IC, an OIS and the like of the rear camera generate certain substrate power consumption after being loaded with power, so that the power consumption is wasted. For example, the OIS may enter a standby mode (i.e., standby mode) after power is applied thereto. OIS generates a substrate current of 3-5mA even in the off-screen state in standby mode, and thus there is some power consumption.

When the PMU loads power to the control chip of the target camera, the control chips of other cameras and the control chip of the target camera share the power port of the same PMU, so that the PMU can load power to the control chips of other cameras at the same time. At this time, the control chips of other cameras enter a standby state. In response to the photographing instruction, the electronic device may transmit a sleep instruction to a control chip of the other camera than the target camera. The sleep instruction may be transmitted in the form of an I2C signal. The sleep command may be input through a mode port on the control chip different from the power port, instructing the control chip to enter a sleep state from a standby state. The control chip entering the sleep state has no additional power consumption.

The shooting instruction may be an instruction input by a user to manually click on a screen of the electronic device to open the camera APP to enter a shooting state, or an instruction input by a user to open the camera APP by voice, which is not limited in the embodiment of the present application. Optionally, the shooting instruction may also be an instruction to open the front camera to a normally open state, for example, an instruction for a user to open a function of detecting a gesture in real time or detecting a face in real time. Optionally, the shooting instruction may also be an instruction input by a user to open a camera in an online-on-camera (AON) mode. If the front camera is in an AON mode when the electronic equipment is started by default, the shooting instruction is an instruction for loading the camera after the electronic equipment is started. The application does not limit the specific form of the shooting instruction.

When the target camera is a front camera in a real-time online mode, the electronic device can send a dormancy instruction to each control chip of the rear camera in sequence, so that the control chips such as an AF IC and an OIS corresponding to the rear camera enter a dormancy state, and further, extra power consumption is avoided.

Alternatively, the target camera may be one of the rear cameras. For example, when the rear-mounted main camera is in the AON mode, the electronic device may output a sleep instruction from control chips such as a camera except the main camera and an AF IC of the front-mounted camera in the rear-mounted camera to instruct the control chips to enter a sleep state, so as to avoid generating additional power consumption.

Under the condition that the control chips of all cameras are electrified, the electronic equipment sends a dormancy instruction to the control chips such as AF ICs, OIS and the like of other cameras which are not needed to be used, and instructs the control chips of the other cameras which are not needed to be used to enter a dormancy state, so that the power consumption is saved. According to the method, the power supply mode of the control chip of each camera is not required to be redesigned, and a new power port is not required to be introduced to supply power to different control chips respectively, so that the production and design cost can be guaranteed not to be increased. Meanwhile, the control chips of other cameras are prevented from generating extra power consumption under the condition of not being used, and the power consumption of the whole camera is reduced, so that the standby time is prolonged.

In some possible implementations, the target camera is a front camera and the other cameras are rear cameras.

In general, the front camera needs to monitor the face or the gesture in real time, and can be set to be in a normally open state. The rear camera can be opened or closed as required.

In some possible implementations, when the front camera is in the real-time online AON mode, sending a sleep instruction to a control chip corresponding to another camera includes: sending a dormancy instruction to control chips corresponding to other cameras through an AON interface of a hardware abstraction layer; the method further comprises the steps of: the intelligent sensing hub is used for controlling the front-mounted camera to shoot.

It should be noted that, in the current electronic device, the strategy of camera mapping is divided into two cases. An AP side map in a non-AON mode, and a Sensor Hub side map in an AON mode. When the front camera is in an AON mode, under the condition that other cameras are not used, the electronic equipment sends a dormancy instruction to the control chip corresponding to the other cameras through the AON interface of the hardware abstraction layer, and the control chip of the unused camera is instructed to enter a dormancy state to save power consumption.

In some possible implementations, when the front camera is not in the AON mode, sending a sleep instruction to a control chip corresponding to another camera includes: sending a dormancy instruction to control chips corresponding to other cameras through the camera hardware abstraction layer; the method further comprises the steps of: and driving and controlling the front camera to shoot through the front camera of the inner core layer.

When the front camera is in an AON mode, under the condition that other cameras are not used, the image strategy of the electronic equipment is executed on the AP side, and the electronic equipment sends a dormancy instruction to a control chip corresponding to the other cameras through an AON interface of a hardware abstraction layer to instruct the control chip of the unused camera to enter a dormancy state so as to save power consumption. Meanwhile, the electronic equipment controls the front camera to draw through the Sensor Hub.

In some possible implementations, the target camera includes a front camera and a main camera in the rear camera, the front camera is in an AON mode, and sending a sleep instruction to a control chip corresponding to the other cameras includes: sending a dormancy instruction to control chips corresponding to other cameras through an AON interface of a hardware abstraction layer; the method further comprises the steps of: and controlling the intelligent sensing hub to control the front camera to shoot through the AON interface.

When a user opens a main camera in the rear camera to shoot, and the front camera is in a normally open state, the target camera comprises the front camera and the main camera. If the front camera is in the AON mode, the electronic equipment can send a dormancy instruction to the control chip corresponding to other cameras through the AON interface of the hardware abstraction layer, and the control chip of the unused camera is instructed to enter a dormancy state so as to save power consumption. Meanwhile, the electronic equipment controls the front camera to be mapped through the Sensor Hub, and the electronic equipment also controls the main camera to be mapped through the main camera drive of the kernel layer.

In some possible implementations, the target camera includes a front camera and a main camera in the rear camera, the front camera is not in an AON mode, and sending a sleep instruction to a control chip corresponding to the other cameras includes: sending a dormancy instruction to control chips corresponding to other cameras through the camera hardware abstraction layer; the method further comprises the steps of: and driving and controlling the front camera to shoot through the front camera of the inner core layer.

When a user opens a main camera in the rear camera to shoot, and the front camera is in a normally open state, the target camera comprises the front camera and the main camera. If the front camera is not in the AON mode, the electronic equipment can send a dormancy instruction to the control chip corresponding to other cameras through the camera hardware abstraction layer, and the control chip of the unused camera is instructed to enter a dormancy state so as to save power consumption. Meanwhile, the electronic equipment controls the main camera to be drawn through the main camera drive of the kernel layer, and controls the front camera to be drawn through the front camera drive of the kernel layer.

In some possible implementations, the target camera is a main camera in the rear camera, the main camera is in an AON mode, and sends a sleep instruction to a control chip corresponding to the other cameras, including: sending a dormancy instruction to control chips corresponding to other cameras through an AON interface of a hardware abstraction layer; the method further comprises the steps of: and controlling the intelligent sensing hub to control the main camera to shoot through the AON interface.

When a user opens a main camera in the rear camera to shoot, and the front camera is not opened, if the main camera is in an AON mode, the electronic equipment can send a dormancy instruction to control chips corresponding to other cameras through an AON interface of a hardware abstraction layer, and the control chips of the unused cameras are instructed to enter a dormancy state to save power consumption. Meanwhile, the electronic equipment controls the main camera to be mapped through the Sensor Hub.

In some possible implementations, the target camera is a main camera in the rear camera, the main camera is in an AON mode, and sends a sleep instruction to a control chip corresponding to the other cameras, including: sending dormancy instructions to control chips corresponding to other cameras except the main camera in the rear camera through an AON interface of the hardware abstraction layer; the method further comprises the steps of: the intelligent sensing hub is controlled to control the main camera to shoot through the AON interface, and the front camera is controlled to shoot through the front camera driving of the inner core layer.

When a user opens a main camera in the rear camera to shoot, and the front camera defaults to be in a normally open state, if the main camera is in an AON mode, the electronic equipment can send a dormancy instruction to control chips corresponding to other cameras of the non-main camera and the non-front camera through an AON interface of a hardware abstraction layer, and the control chips corresponding to the non-main camera and the other cameras of the non-front camera are instructed to enter the dormancy state to save power consumption. Meanwhile, the electronic equipment controls the main camera to be mapped through the Sensor Hub, and controls the front camera to be mapped through the front camera driving of the kernel layer.

In some possible implementations, the control chip includes an auto-focus chip and/or an image stabilizer.

Typically, the master camera will be equipped with an image stabilizer OIS. Each camera is provided with an automatic focusing chip to realize the automatic focusing chip.

For easy understanding, the following embodiments of the present application will take a terminal device having a structure shown in fig. 1 and fig. 2 as an example, and specifically describe a management method of a control chip provided by the embodiments of the present application in conjunction with the accompanying drawings and application scenarios.

In order to make the shooting functions of the terminal equipment increasingly richer and improve the shooting effect, the functions and scenes supported by the camera of the terminal equipment are also increasingly more and more. In some scenarios, for example, in the case of supporting functions such as spaced gestures and face detection, it is often necessary that the front camera be always on to ensure that external gestures or faces can be recognized at any time. The front camera often also configures an AF IC to realize an auto-focusing function of the front camera, thereby improving the shooting effect of the front camera. Specifically, the terminal device needs to supply power to the AF IC of the front camera in a state that the front camera is normally open, and drives the motor of the front camera to move through the AF IC, so as to realize automatic focusing. In the current terminal equipment, an AF IC of a front camera supplies power through a power port of a PMU. For example, the power port of the AF IC of the front camera is connected with one path of LDO power port of the PUM to supply power. Typically, the cameras on the terminal device include more than one front camera and one or more rear cameras. The rear camera can also realize automatic focusing under the control of the corresponding AF IC. Some rear cameras also often have OIS configured to prevent shake. In order to save cost, the same path of LDO power supply is generally used for supplying power to devices such as AF IC, OIS and the like of all cameras.

For terminal equipment powered by the same power supply for devices such as AF ICs and OIS of a plurality of cameras, the AF ICs and OIS of the rear cameras can be loaded with the power supply together when the AF ICs of the front cameras are required to be loaded with the power supply (simply called power-on). The devices which are not needed to be used in the current state such as an AF IC, an OIS and the like of the rear camera generate certain substrate power consumption after being loaded with power, so that the power consumption is wasted. For example, the OIS may enter a standby mode (i.e., standby mode) after power is applied thereto. OIS generates a substrate current of 3-5mA even in the off-screen state in standby mode, and thus there is some power consumption.

The embodiment of the application provides a management method of a control chip, when one camera is opened, terminal equipment sends a dormancy instruction to devices such as AF ICs, OIS and the like of other unused cameras, and indicates the devices such as AF ICs, OIS and the like of the unused cameras to enter a dormancy state (sleep mode). The power consumption of the device entering the sleep state is lower than that in the standby mode after power-up, so that the power consumption can be saved.

The management method of the control chip provided by the embodiment of the application can be applied to terminal equipment comprising a plurality of cameras. In general, a camera disposed on a screen side of a terminal device is referred to as a front camera, and a camera disposed on a rear case side of the terminal device is referred to as a rear camera. Typically the latter camera typically comprises more than one camera, for example a main camera, and may comprise one or more of a tele camera, a wide camera and a macro camera. The terminal device can select to call different cameras or different camera combinations to shoot under different shooting modes or shooting requirements. Each camera is provided with a corresponding control chip, and various shooting functions are realized under the control of the corresponding control chip. For example, the camera can realize automatic focusing under the control of a corresponding AF IC and realize optical anti-shake under the control of OIS.

Fig. 3 is a schematic diagram of a management flow of a control chip according to an embodiment of the present application. Specifically, the method can comprise the following steps:

S301, acquiring a shooting instruction, wherein the shooting instruction is used for instructing a target camera to shoot.

When a user wants to take a picture by using the terminal equipment, an application program such as a camera APP can be opened to open a camera to take a picture. The terminal device can then receive and recognize a shooting instruction input by an operation performed by the user to turn on the camera APP or turn on a certain shooting mode. And responding to the shooting instruction, the terminal equipment opens the corresponding target camera in the current shooting mode, and simultaneously supplies power to a control chip of the target camera so as to shoot. For example, when a user opens an application of the camera APP and adjusts to a self-timer mode, the terminal device may open the front-facing camera. The shooting instruction may be an instruction input by a user to manually click on a screen of the terminal device, or may be an instruction input by a user through voice, which is not limited in the embodiment of the present application.

Optionally, the shooting instruction may also be an instruction to open the front camera to a normally open state, for example, an instruction for a user to open a function of detecting a gesture in real time or detecting a face in real time. Optionally, the shooting instruction may also be an instruction input by a user to open a camera in an online-on-camera (AON) mode. If the terminal equipment is started by default, the front camera is in an AON mode, and the shooting instruction is an instruction for loading the camera after the terminal equipment is started. The application does not limit the specific form of the shooting instruction.

S302, responding to shooting instructions, sending dormancy instructions to control chips of other cameras so as to instruct the control chips of the other cameras to enter a dormancy state, wherein the target camera is different from the other cameras.

When the PMU loads power to the control chip of the target camera, the control chips of other cameras and the control chip of the target camera share the power port of the same PMU, so that the PMU can load power to the control chips of other cameras at the same time. At this time, the control chips of other cameras enter a standby state. In response to the photographing instruction, the terminal device may transmit a sleep instruction to the control chip of the other cameras other than the target camera. The sleep instruction may be transmitted in the form of an I2C signal. The sleep command may be input through a mode port on the control chip different from the power port, instructing the control chip to enter a sleep state from a standby state. The control chip entering the sleep state has no additional power consumption.

When the target camera is a front camera in a real-time online mode, the terminal equipment can send a dormancy instruction to each control chip of the rear camera in sequence, so that the control chips such as an AF IC and an OIS corresponding to the rear camera enter a dormancy state, and further, extra power consumption is avoided.

Alternatively, the target camera may be one of the rear cameras. For example, when the rear-mounted main camera is in the AON mode, the terminal device may output a sleep instruction from control chips such as a camera except the main camera and an AF IC of the front-mounted camera in the rear-mounted camera to instruct the control chips to enter a sleep state, so as to avoid generating additional power consumption.

In the embodiment shown in fig. 3, when the control chips of all the cameras are powered on, the terminal device sends a sleep instruction to the control chips of the AF ICs, OIS, etc. of the other cameras that do not need to be used, so as to instruct the control chips of the other cameras that do not need to be used to enter a sleep state, thereby saving power consumption. According to the method, the power supply mode of the control chip of each camera is not required to be redesigned, and a new power port is not required to be introduced to supply power to different control chips respectively, so that the production and design cost can be guaranteed not to be increased. Meanwhile, the control chips of other cameras are prevented from generating extra power consumption under the condition of not being used, and the power consumption of the whole camera is reduced, so that the standby time is prolonged.

It should be noted that, in the current terminal device, the strategy of camera mapping is divided into two cases.

One common pattern (pattern in non-AON mode) is that the execution flow is at the AP (application process, application processor CPU of the terminal device) side. Specifically, referring to fig. 4, in fig. 4, a current opened camera is taken as a front camera, and the front camera is in a normally open mode to detect a gesture or a scene of a face, for example, to describe a graph flow of the camera. When a user opens the front-facing camera through operating the camera APP of the APP layer of the terminal equipment and is in a normal open mode, the camera APP responds to the operation of the user and transmits the drawing instruction of the front-facing camera to the lower layer by layer. Specifically, the camera APP delivers a map instruction to a camera system library layer (also called a hardware abstraction layer, CAMERA HARDWARE abstraction layer, CAMERA HAL for short) through a Java native interface (Java NATIVE INTERFACE, JNI) of an application Framework (FWK) layer. CAMERA HAL in turn pass the map instructions down to the front-end camera driver (e.g., AON CAMERA DRIVER, which may also be referred to as V4L2 node) of the Kernel layer (Kernel) through the camera service layer interfaces (CAMERA SERVICE LAYER INTERFACE, CSL INTERFACE). The front camera drive instructs the front camera to collect images to shoot pictures under the instruction of the picture command. Alternatively, the map instruction may be described as: msgid-aon_camera_is_work. Meanwhile, in the technical scheme of the embodiment of the application, the kernel layer is additionally provided with nodes corresponding to the control chips of other non-front cameras. Taking a newly added node as a node (named as/dev/hicam _ OIS /) of the OIS of the post-positioned main camera as an example, the node of the OIS of the main camera is called a main camera OIS driver, and CAMERA HAL sends a drawing instruction downwards and also sends a dormancy instruction to the node/dev/hicam _ OIS/by adopting an input/output control (I/O CTL) instruction. For example, the sleep instruction may be described as: HICAM _ois_sleep. The node of the OIS may be described as a master camera OIS driver (e.g., custom camera OIS Driver) at the kernel layer, where the master camera OIS driver controls the corresponding OIS to enter a sleep state under the instruction of a sleep instruction. OIS entering sleep state has no additional power consumption.

In general, a corresponding AF IC is further provided for the main camera in the terminal device to achieve auto-focusing of the main camera. When the terminal equipment is in a normally open state of the front camera, a dormancy instruction can be sent to a driver (for short, a driver) of the AF IC of the main camera which is newly added in the kernel layer, so that the AF IC of the main camera also enters a dormancy state.

The second strategy of camera mapping is applied in AON mode. The AON mode will be first described here: the AON mode is an energy efficient real-time operating system running at ultra low power consumption, which runs on the Sensor Hub side (as opposed to the AP side). Typically, the hardware layer of the terminal device will set a Sensor Hub. The Sensor Hub can be connected with sensors such as ambient light and a proximity light Sensor, and a low-power-consumption strategy is realized. The AON mode is a strategy with low power consumption of the real-time online camera. The Sensor Hub is provided with an AON control module and an AON function related firmware (AON firmware, AON FW). The current opened camera is taken as a front camera, and the front camera is in an AON mode to detect a gesture or a scene of a human face for describing the picture flow of the camera. Continuing to refer to the flow shown in fig. 4, when the user opens the front-end camera by operating the camera APP of the APP layer of the terminal device and the front-end camera is in the AON mode, the camera APP responds to the operation of the user and transmits the graphics instruction of the front-end camera according to the AON mode to the lower layer by layer. Specifically, the camera APP transmits a map instruction to an AON interface (AON interface description language, AON HIDL) of the system library through a Java local interface of the application framework layer. The AON service receives the map instruction through the AON HIDL, and passes the map instruction down to the Sensor Hub through a lower-layer-oriented AON interface (HSEEAON interface) of the system library under the support of the AON service (AON service). The msgid message identity (MESSAGE IDENTITY documents, msgid) of the map instruction may be described as: msgid-aon_camera_is_work. The Sensor Hub receives a map instruction through an AON control module (AON control), and then under the support of AON FW, the AON camera (i.e. the front camera) is controlled to map in an AON mode. Meanwhile, in the technical scheme of the embodiment of the application, the corresponding node of the kernel layer is operated through HSEEAON interface of the system library, for example, a dormancy instruction is sent to the OIS node/dev/hicam _ OIS of the main camera. For example, the sleep instruction may be described as: HICAM _ois_sleep. In the process of downward transmission of the graphic instruction, the module at the lower layer can reply a message to the upper layer after receiving the graphic instruction to indicate that the transmission of the graphic instruction is successful.

In the foregoing, the process of setting the OIS of the rear-mounted main camera to the sleep state is described by taking the front-mounted camera as an example. Meanwhile, the AF IC of the main camera is not required to be used, so that the AF IC of the main camera can be configured to enter a sleep state at the same time. Of course, if the main camera is provided with other control chips, the control chip and the control chip of the front camera may be configured to enter the sleep state under the condition that the control chip and the control chip of the front camera share the same power supply.

It should be noted that, even if other control chips of the camera that do not need to be used are forced to be powered on, the terminal device can send a sleep instruction to the drive corresponding to the control chip of the camera that does not need to be used, so as to instruct the control chip of the camera that does not need to be used to enter a sleep state, thereby saving power consumption. The specific manner may refer to a manner of sending the dormancy instruction to the OIS driver of the master camera, and only the sending object of the dormancy instruction is different, which is not described herein. After the graph instruction is successfully transferred downwards, a feedback message of successful transfer is replied to an upper layer.

In the actual use process, corresponding drivers (MISC DEVICE) can be set in the kernel layer for different control chips of each camera, for example, the drivers of AF ICs and OIS of control chips of a tele camera, a wide camera and the like. When a certain camera is not needed to be used, even if the camera is forced to be electrified, the terminal equipment can send a dormancy instruction to a drive corresponding to a control chip of the unused camera through the image processing module or HSEEAON interface to instruct the control chip of the unused camera to enter a dormancy state, so that the power consumption is saved. The manner in which the terminal device sends the sleep instruction to the drive of the control chip such as the AF IC and OIS of the unused camera may be the same as the manner in which the sleep instruction is sent to the main camera OIS drive, which is not described here again.

In one case, when the front camera is in a normal open state or in an AON mode, the rear main camera may also be capturing and displaying the preview interface, that is, both the front camera and the rear main camera are simultaneously in the drawing. The image processing module or HSEEAON interface can send a dormancy instruction to the drive of the control chips of the rear-mounted long-focus camera and the wide-angle camera to instruct the control chips of the long-focus camera and the wide-angle camera to enter a dormancy state, so that invalid power consumption is reduced as much as possible while normal image drawing of the camera is ensured, and power consumption configuration is more reasonable.

The process of how the front-end camera sends the sleep instruction in the process of drawing is described in the foregoing, and the condition of outputting the sleep instruction in the process of turning on the camera for shooting by a user is described next.

Fig. 5 is a flowchart of a method for controlling a chip to enter a sleep state according to an embodiment of the present application. The method specifically comprises the following steps:

s501, starting a target camera.

When a user inputs a shooting instruction, starting a corresponding target camera to work when starting the camera APP.

Specifically, the target camera is related to the current shooting scene. For example, when a user turns on the camera APP to capture a landscape, the target camera is one or more of the rear cameras, such as a camera and a tele camera; when a user opens the camera APP to perform self-timer or detect a face or a gesture, the target camera is a front-mounted camera. Correspondingly, the shooting instruction is an instruction input by opening the camera APP and entering a shooting scene. Optionally, the shooting instruction may also be an instruction to open the front camera to a normally open state, for example, an instruction for a user to open a function of detecting a gesture in real time or detecting a face in real time. Optionally, the shooting instruction may also be an instruction input by the user to open the AON mode of the camera. If the terminal equipment is started by default, the front-facing camera is in an AON mode, and the shooting instruction is an instruction for starting the terminal equipment and loading the front-facing camera. Alternatively, the shooting instruction may be an instruction to turn on the AON mode of the rear camera. The application does not limit the specific form of the shooting instruction.

S502, judging whether the current camera is a front camera or not. If yes, executing S503A; if not, S503B is performed.

The terminal equipment judges whether the currently started target camera is a front camera or not. If the currently started target camera is a front-end camera, the terminal equipment sends a picture command to the front-end camera from the lower part of the application program layer, so that the front-end camera shoots pictures.

Optionally, the front camera may also be in an AON mode, and if the front camera is in the AON mode, the mapping process may be performed on the senser hub side; alternatively, if the front camera is not in AON mode, the mapping procedure may be performed on the AP side. If the currently started target camera is not the front camera but the rear camera, a graph instruction is issued to the rear camera so that the rear camera can shoot a graph. The flow of the camera may be described with reference to the embodiment of fig. 4, and will not be described herein.

S503A, outputting a dormancy instruction to a control chip of the other cameras which are not the front-end cameras.

If the currently started target camera is a front camera, the other cameras which are not the front cameras do not need to work. The terminal device can output a sleep instruction to the control chips of other cameras, such as the rear main camera, the long-focus camera and the wide-angle camera, so that the control chips of the other cameras enter a sleep state to save power consumption.

If the rear-mounted main camera is started currently, and the front-mounted camera still needs to be kept in a normally-open state to detect the face or the gesture, the target camera is the front-mounted camera and the main camera. The other cameras are cameras which are not main cameras in the rear camera. And the terminal equipment outputs a dormancy instruction to the control chips of the other cameras which are not the front camera and the main camera so as to enable the control chips of the other cameras to enter a dormancy state. Meanwhile, the terminal device may also perform the step of S504.

S503B, judging whether the target camera is a camera in AON mode operation (called AON camera for short). If yes, executing S505A; if not, S505B is executed.

And if the currently started target camera is not the front camera, indicating that the target camera is one or more of the rear cameras. For example, if the target camera is the main camera in the rear camera, it is indicated that the front camera and the other cameras except the main camera in the rear camera do not need to work, and the terminal device can output a sleep instruction to the control chips of the front camera and the other cameras in the rear camera, so that each control chip of the front camera and the other cameras enters a sleep state to save power consumption.

For another example, when the target camera is the main camera and the wide-angle camera in the rear camera, it is indicated that the front camera and the other cameras except the main camera and the wide-angle camera in the rear camera do not need to work. The terminal device can output a sleep instruction to the control chips of the front camera and the other cameras except the main camera and the wide-angle camera in the rear camera, so that the control chips of the front camera and the other cameras enter a sleep state to save power consumption.

S504, the control target camera executes a graph flow.

The flow of the camera may be described with reference to the embodiment of fig. 4, and will not be described herein.

S505A, sending dormancy instructions to other cameras of the non-target cameras.

For example, the currently started target camera is not the front camera but the main camera in the rear camera, and the main camera is in the AON mode, and the terminal device may send a sleep instruction to the control chips of other cameras such as the tele camera and the wide camera of the non-main camera in the rear camera, so as to instruct the control chips of the other cameras to enter the sleep state to save power consumption.

When the target camera is not a front camera but is a camera in the AON mode, the terminal device may execute the image flow of the target camera on the senser hub side.

S505B, executing the drawing flow of the target camera.

When the target camera is neither a front camera nor a camera in the AON mode, the terminal device may execute the image flow of the target camera on the AP side.

The specific implementation process of S505B may also refer to the related description of the embodiment of fig. 4, which is not repeated herein.

In the embodiment shown in fig. 5, when the currently started target camera is the front camera, the terminal device outputs a sleep instruction to the control chip of the other rear camera, so as to instruct the control chip of the rear camera not to be used to enter a sleep state, thereby saving power consumption; and under the condition that the target camera is not a front camera, according to whether the target camera is in an AON mode or not, a corresponding module is adopted to output a dormancy instruction, and a control chip of the unused camera is instructed to enter a dormancy state, so that the power consumption is saved. The method can flexibly output the dormancy instructions to different objects according to the using states of the cameras, so that the power consumption saving mode is more reasonable.

Alternatively, if only the front camera on the terminal device supports the AON mode, and none of the other cameras support the AON mode, the specific procedure of using the embodiment shown in fig. 5 is as follows: firstly judging whether a target camera is a front camera or not; if yes, outputting a dormancy instruction to control chips of other cameras through an image processing module (camX), and executing a drawing flow of the front camera on the AP side; if not, continuing to judge whether the target camera is an AON camera. If the target camera is an AON camera, outputting a dormancy instruction to control chips of other cameras through HSEEAON interfaces, and executing the drawing flow of the AON camera on the senser hub side. If the target camera is not the AON camera, executing a drawing flow of the target camera at the AP side; meanwhile, a dormancy instruction is output to control chips of other cameras through an image processing module (camX).

Optionally, the terminal device may further directly determine whether the currently started target camera is in the AON mode to output the sleep instruction, and specifically may refer to a flow shown in fig. 6, including:

s601, starting a target camera.

The S601 may be referred to the description of S501 hereinabove, and will not be repeated here.

S602, judging whether the target camera is in an AON mode. If yes, executing S603A; if not, S603B is executed.

S603A, the terminal equipment outputs a dormancy instruction to the control chips of other cameras through HSEEAON interfaces.

If the target camera is in the AON mode, the terminal equipment can control the target camera to execute a drawing flow on the senser hub side; meanwhile, a dormancy instruction is output to control chips of other cameras through HSEEAON interfaces.

S603B, the terminal equipment outputs dormancy instructions to control chips of other cameras through the image processing module.

If the target camera does not have the AON mode, the terminal equipment can control the target camera to execute a drawing flow on the AP side; meanwhile, a dormancy instruction is output to control chips of other cameras through an image processing module (camX).

S604, executing a drawing flow of the target camera.

The specific process of step S604 may be referred to the embodiment shown in fig. 4, and will not be described herein.

Optionally, when the target camera is not in the AON mode, the terminal device may further continue to determine whether the target camera is a front camera. If yes, the terminal equipment executes a drawing flow on the AP side, and simultaneously sends a dormancy instruction to a control chip of the rear camera through an image processing module (camX); if not, the terminal device executes the drawing flow at senser hub side; and simultaneously, outputting a dormancy instruction to the control chip of the front camera and the unused rear camera through the HSEEAON interface. Optionally, if only the front camera in the cameras of the terminal device supports the AON mode, the target camera is not in the AON mode, and when the target camera is not the front camera, the dormancy instruction can be sent to the control chip of the other rear cameras, and the dormancy instruction is not required to be sent to the front camera, so that the front camera can be in a normally open state, and the function of real-time detection is ensured. Meanwhile, the front camera normally works out to ensure the normal operation of the function of detecting the face or gestures.
