Description
Technical Field
The present disclosure relates to the field of computer technologies, and in particular, to a frame rate control method, apparatus, and device.
Background
Today, electronic devices such as smartphones, tablet computers, etc. are often configured with a camera module, and when a user wants to take an image, the electronic device can activate the camera module and display a preview image, and the user can adjust the shooting angle according to the preview image.
However, in the prior art, the preview image of the electronic device is usually displayed at a fixed frame rate, if the user is in a scene moving at a high speed, the fixed frame rate is relatively low, the preview image may be jammed, and if the user is in a static state, the fixed frame rate is relatively high, which causes resource waste.
Disclosure of Invention
In view of this, the present application provides a frame rate control method, apparatus and device, so as to solve the problem that the preview frame rate in the prior art is difficult to satisfy different shooting scenes.
In a first aspect, an embodiment of the present application provides a frame rate control method, where the method is applied to an electronic device, when the electronic device detects that a camera module is started, current motion gesture information of the electronic device is obtained, a state type of the electronic device can be determined according to the motion gesture information, and then a preview frame rate of the camera module is adjusted based on the state type.
In the embodiment of the application, the electronic device dynamically adjusts the preview frame rate of the camera module based on the current state type of the electronic device, when the electronic device moves fast, the electronic device can set a higher preview frame rate so as to ensure smooth pictures, and when the electronic device is static, the electronic device can set a lower preview frame rate, so that the electric quantity is saved.
In an alternative manner, the status type of the electronic device may include: a stationary state, a first motion state, or a second motion state; wherein the speed of the electronic device in the second motion state is greater than the speed of the electronic device in the first motion state.
In an alternative manner, when the electronic device adjusts the preview frame rate of the camera module based on its own state type, the electronic device first obtains a preset frame rate associated with the current state type of the electronic device, and then adjusts the preview frame rate of the camera module with the preset frame rate as the frame rate to be adjusted.
In the embodiment of the application, the electronic device may pre-configure the associated preview frame rate for different status types, and after determining the current status type of the electronic device, the electronic device may acquire the corresponding preset frame rate, so as to adjust the preview frame rate of the camera module.

In the embodiment of the application, the electronic equipment sets different frame rates according to different state types, so that smooth pictures can be ensured, and electric quantity waste can be avoided.
In an alternative manner, when the electronic device adjusts the preview frame rate of the camera module based on the state type, the electronic device first acquires the preview image collected by the camera module, and then adjusts the preview frame rate of the camera module based on the preview image and the current state type of the electronic device. Specifically, if the preview image is detected to contain preset content information and the state type of the electronic device is a preset specified type, the electronic device sets the preview frame rate to be a fourth frame rate; the preset content information comprises: an object having a movement capability and a speed at which it moves can exceed a first threshold.
In this embodiment of the present application, if the electronic device detects that there is an object that may be moving or is moving rapidly in the preview image, the preview frame rate needs to be set to a higher frame rate even if the moving speed of the device itself is low.
In an alternative manner, when the electronic device adjusts the preview frame rate of the camera module based on the state type, if the frame rate to be adjusted determined based on the state type is different from the configured frame rate of the camera module, and the difference between the setting time of the configured frame rate and the current time is greater than the second threshold, the electronic device may set the preview frame rate of the camera module to the frame rate to be adjusted, otherwise, the configured frame rate of the camera module is kept unchanged.

Detailed Description
For a better understanding of the technical solutions of the present application, embodiments of the present application are described in detail below with reference to the accompanying drawings.
It should be understood that the described embodiments are merely some, but not all, of the embodiments of the present application. All other embodiments, based on the embodiments herein, which would be apparent to one of ordinary skill in the art without making any inventive effort, are intended to be within the scope of the present application.
The terminology used in the embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that the term "and/or" as used herein is merely one way of describing an association of associated objects, meaning that there may be three relationships, e.g., a and/or b, which may represent: the first and second cases exist separately, and the first and second cases exist separately. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
In the prior art, the step of activating the camera module by the electronic device may be as shown in fig. 1. When a user needs to shoot an image, the camera module of the electronic device can be started manually, and the electronic device controls the camera module to start in response to a starting request of the user. After the camera module is started, the preview image collected by the electronic equipment through the camera module can be displayed in a screen so as to enable a user to adjust the shooting angle. In this process, the state type of the electronic device may change, for example, the user is initially stationary somewhere, and after a certain period of time, the user starts walking, and after a certain period of time, the user starts running. In contrast, the state type of the electronic device is changed from stationary to slow movement, and then from slow movement to fast movement. Regardless of the state type of the electronic device, the preview frame rate of the camera module is configured with a fixed value, and the preview image in the screen is displayed with a fixed frame rate. When the electronic device is in different state types, the most suitable preview frame rate is also different, and the camera module is configured only with one fixed frame rate, so that different scenes are difficult to be suitable.
Aiming at the problems, the embodiment of the application can dynamically adjust the preview frame rate of the camera module based on the current state type of the electronic equipment, and can set higher preview frame rate when the electronic equipment moves fast so as to ensure smooth pictures, and can set lower preview frame rate when the electronic equipment is static, thereby saving electric quantity.
In the embodiment of the present application, the step of the electronic device activating the camera module may be as shown in fig. 2. After the electronic device starts the camera module, the preview picture collected by the camera module is displayed on the screen, and in the process, if the state type of the electronic device changes, the electronic device dynamically configures the preview frame rate of the camera module. Specifically, the preview frame rate of the camera module may be determined by the preview frame rate adjustment module 200, and the preview frame rate adjustment module 200 is internally provided with: a sensor 201, a sensor data processing module 202, a mobile sensing platform (Mobile Sensing Development Platform, MSDP) module 203, a preview frame rate decision module 204, and a preview frame rate output module 205. The sensor 201 is configured to collect related data such as speed data, acceleration data, and gesture data of the electronic device, and the sensor data processing module 202 performs preliminary processing on the data and sends the data to the MSDP module 203.MSDP module 203 may determine a status type (e.g., a stationary status, a slow moving status, a fast moving status, etc.) of the electronic device based on the received data and send the status type to preview frame rate decision module 204. The preview frame rate decision module 204 can determine the corresponding preview frame rate based on the current status type of the electronic device, with the preview frame rates corresponding to different status types being generally different. The preview frame rate output module 205 may output the final determined preview frame rate based on which the electronic device configures the camera module.
When the preview frame rate decision module determines the corresponding preview frame rate, the preview frame rate decision module can be comprehensively considered in combination with the preview image besides the current state type of the electronic equipment. The workflow of the preview frame rate decision module may be as shown in fig. 3, and may specifically include:
step 301, determining a state type of an electronic device;
step 302, if the electronic device is in a high-speed moving state, matching a third frame rate;
step 303, judging whether an object which is likely to move at a high speed is identified or not when the electronic equipment is in a static state, and if so, entering step 305; if not, go to step 304;
step 304, if the electronic device is in a static state and does not recognize an object which can move at a high speed, matching a first frame rate;
step 305, the electronic device is in a static state and recognizes an object which is likely to move at a high speed, and then matches a fourth frame rate;
step 306, judging whether an object which is likely to move at a high speed is identified or not when the electronic equipment is in a low-speed moving state, and if so, entering step 307; if not, go to step 308;
step 307, the electronic device is in a low-speed moving state and recognizes an object that may move at a high speed, and matches the fourth frame rate;
step 308, the electronic device is in a low-speed moving state and does not recognize an object which can move at a high speed, and the second frame rate is matched;
step 309, judging whether the adjustment condition is met;
step 310, outputting a frame rate to be adjusted;
step 311, the frame rate to be adjusted is not output.
First, the preview frame rate decision module determines the current status type of the electronic device according to the information sent by the MSDP module. Based on motion gesture information such as speed, acceleration, angular velocity, etc. of the electronic device, the state types thereof may be classified into a stationary state, a low-speed moving state, and a high-speed moving state. The low-speed moving state may refer to a scene in which a user is walking normally, and the high-speed moving state may refer to a scene in which a user is running or riding a vehicle. The state types and corresponding specific scenarios disclosed in the embodiments of the present application are only exemplary descriptions, and the number of the state types is not limited, and other reasonable state types may be included besides the three state types.
For scenes with different state types of the electronic equipment, the preview frame rate decision module can match different preview frame rates for the camera module, specifically, when the electronic equipment is in a static state, the preview frame rate decision module matches a first frame rate for the electronic equipment, when the electronic equipment is in a low-speed moving state, the preview frame rate decision module matches a second frame rate for the electronic equipment, and when the electronic equipment is in a high-speed moving state, the preview frame rate decision module matches a third frame rate for the electronic equipment. The third frame rate is numerically greater than the second frame rate, which is greater than the first frame rate. It will be appreciated that when the electronic device is in a stationary state, the camera module may have a lower frame rate requirement, the preview frame rate may be set to a first frame rate, when the electronic device is in a low-speed moving state, the camera module may have a higher frame rate requirement, the preview frame rate may be set to a second frame rate, and when the electronic device is in a high-speed moving state, the camera module may have a higher frame rate requirement, the preview frame rate may be set to a third frame rate. Therefore, the preview frame rate can meet the shooting requirement of the camera module, and the electric energy waste caused by the overhigh frame rate can be avoided.
If there is an object that may move at a high speed in the current photographing scene under the condition that the electronic device is in a stationary state or a low-speed moving state, the preview frame rate of the camera module needs to be increased. The electronic device may pre-record common objects that have mobility and that are moving at a speed exceeding a first threshold, such as animals like cats, dogs, or vehicles like automobiles, airplanes. When the object that may move at a high speed moves, the camera module needs a higher preview frame rate to clearly display the preview image, so the preview frame rate decision module may match the fourth frame rate for the camera module when detecting that the preview image contains the preset content information. Wherein the fourth frame rate is greater than the first frame rate and greater than the second frame rate. The third frame rate is a frame rate corresponding to the electronic device in the high-speed moving state, and has a higher value, and when the camera module configures the third frame rate, the camera module is sufficient to clearly display the preview image even if the object moving at high speed appears in the preview image, so that it is not necessary to determine whether the object moving at high speed is identified in the preview image between step 301 and step 302. Alternatively, the fourth frame rate may be the same as the third frame rate or may be different from the third frame rate.
After the preview frame rate decision module matches any frame rate for the camera module, the matched frame rate can be used as the frame rate to be adjusted S1, and before outputting the frame rate to be adjusted S1, the preview frame rate decision module needs to judge whether the current frame rate to be adjusted S1 meets the adjustment condition. The current system time may be denoted as T1, the configured frame rate of the camera module may be denoted as S2, and the configured time may be denoted as T2. The preview frame rate decision module needs to judge whether S1 is different from S2, and whether the difference between T1 and T2 is larger than a second threshold, if yes, determining that S1 meets the adjustment condition, otherwise, determining that S1 does not meet the adjustment condition. In an actual shooting scene, the state type of the electronic device may be changed frequently, and if the switching frequency of the preview frame rate is too high, a stronger cracking sense may occur in the preview image, so that user experience is affected. For this case, the second threshold may be reasonably set, and the preview frame rate may be switched only if the frame rate to be adjusted is different from the configured frame rate and the difference between the current time and the last adjustment time is greater than the second threshold. Therefore, the switching interval of the preview frame rate of the camera module is larger, so that the picture splitting feeling caused by switching the preview frame rate at high frequency is avoided.
When the frame rate to be adjusted is determined to meet the adjustment condition, the preview frame rate decision module can output the frame rate to be adjusted, otherwise, the frame rate to be adjusted is not output. The electronic device may set the output frame rate to be adjusted to a preview frame rate of the camera module to be suitable for different shooting scenes.
In this embodiment of the present invention, when the electronic device moves at a high speed or there is a possible high-speed object in the preview screen, the electronic device may set the preview frame rate of the camera module to a higher value to ensure smooth screen, and when the electronic device moves at a low speed or is stationary, the electronic device may set the preview frame rate of the camera module to a lower value to save electric power.

Fig. 6 is a flowchart of a frame rate control method according to an embodiment of the present application. The method may be applied to an electronic device, as shown in fig. 6, and may include:
step 601, when the camera module is detected to be started, current motion gesture information of self equipment is obtained;
step 602, determining the state type of the self equipment according to the motion gesture information;
step 603, adjusting the preview frame rate of the camera module based on the status type.
The motion gesture information may include information such as velocity data, acceleration data, gesture data, and the like, from which the electronic device may determine its own state type.

In an alternative way, the electronic device may further adjust the preview frame rate in combination with the content of the preview image, based on the determination of the status type. Specifically, if an object with moving capability and a speed during moving can exceed a first threshold value exists in the preview screen, the electronic device needs to adjust the preview frame rate to the highest value so as to ensure that the camera module can clearly display the preview image when the object moves. In execution, if the object is detected to be included in the preview image and the state type of the electronic device is a specified type (stationary state or first motion state), the electronic device sets the preview frame rate to a fourth frame rate.
