The control method of the electronic device 100 according to the embodiment of the present application may be implemented by the electronic device 100 according to the embodiment of the present application. For example, the time of flight module 20 may be used to execute the method in 01, and the processor 10 may be used to execute the methods in 02 and 03. That is to say, the time-of-flight module 20 can be used to collect a depth image of a subject. The processor 10 may be configured to switch the main camera 30 or the sub camera 40 according to a predetermined condition to acquire a captured image of the subject; and construct a three-dimensional image of the subject according to the depth image and the captured image.

It can be understood that with the rapid development of electronic technology, electronic devices such as smart phones and tablet computers have become increasingly popular. An electronic device usually collects a captured image of a subject through a single camera, which has insufficient functions and poor user experience.

The control method of the electronic device 100 and the electronic device 100 according to the embodiments of the present application can switch the main camera 30 or the sub camera 40 according to a predetermined condition to capture a captured image of the subject, and also can capture the depth of the captured image based on the captured image and the time of flight module 20 The image builds a three-dimensional image of the subject, which has a variety of functions and is conducive to improving the user experience.

Please refer to FIG. 2 again, the electronic device 100 may be a mobile phone, a tablet computer, a smart watch, a smart bracelet, a smart wearable device, etc. The embodiment of the present application is described by taking the electronic device 100 as a mobile phone as an example. It can be understood that the electronic device 100 The specific form is not limited to mobile phones.

The electronic device 100 may include a case 101 and a bracket 102. The time-of-flight module 20, the main camera 30 and the auxiliary camera 40 are all disposed on the bracket 102. The time-of-flight module 20, the main camera 30, the sub-camera 40, and the bracket 102 are all housed in the casing 101 and can extend from the casing 101. Specifically, when the time-of-flight module 20 is used to collect a depth image of the subject, or the main camera 30 is used to capture a captured image of the subject, or the sub-camera 40 is used to capture a captured image of the subject, the bracket 102 The time-of-flight module 20, the main camera 30, and the sub-camera 40 are driven to move outside the casing 101 to extend the casing 101, so as to acquire a depth image or take an image. In the embodiment of the present application, the time-of-flight module 20, the main camera 30, and the sub-camera may be all front cameras or all rear cameras. The subject can be a person, object, or other subject that the user wishes to photograph. In other embodiments, the housing 101 may be provided with a light through hole (not shown). The time-of-flight module 20, the main camera 30 and the sub camera 40 are immovably disposed in the housing 101 and correspond to the light through hole. . In yet another embodiment, the display screen 103 of the electronic device 100 disposed on the casing 101 may be provided with a light through hole (not shown), and the time-of-flight module 20, the main camera 30 and the sub-camera 40 are disposed on the display screen 103. Below.

In an embodiment, during the operation of the electronic device 100, the processor 10 switches the main camera 30 or the sub-camera 40 according to a predetermined condition to acquire a captured image of the subject (ie, 02), and the processor 10 according to the depth image and The step of capturing the image to construct a three-dimensional image of the subject (ie, 03) is implemented in two different application scenarios, and there is no sequential relationship between step execution between 02 and 03. That is to say, in an application scenario, the processor 10 may switch the main camera 30 or the sub camera 40 according to a predetermined condition to collect a captured image of a subject, thereby realizing an optical zoom and telephoto experience without having to The depth image and the captured image construct a three-dimensional image of the subject. In another application scenario, the processor 10 may choose to construct a three-dimensional image of the subject based on the captured image collected by the main camera 30 and the depth image collected by the time-of-flight module 20, or select the captured image and flight based on the captured image acquired by the secondary camera 40 The depth image collected by the time module 20 constructs a three-dimensional image of the subject, thereby realizing 3D effects and Augmented Reality (AR) applications, without the need to switch the main camera 30 or the sub camera 40 to capture the subject according to predetermined conditions A captured image of the subject.

In another embodiment, during the operation of the electronic device 100, the processor 10 switches the main camera 30 or the sub-camera 40 according to a predetermined condition to acquire a captured image of the subject (ie, 02), and the processor 10 according to the depth image The step of constructing a three-dimensional image of the object and the captured image (ie, 03) is implemented in the same application scenario, and 02 is executed before 03. That is, the processor 10 first switches to capture a captured image of the subject according to a predetermined condition, and then constructs a three-dimensional image of the subject based on the depth image and the captured image captured by the main camera 30; or, the processor 10 First, switch to the sub-camera 40 to capture a captured image of the subject according to a predetermined condition, and then construct a three-dimensional image of the subject based on the depth image and the captured image collected by the sub-camera 40. In the embodiment of the present application, since the processor 10 first selects an appropriate camera to collect a captured image of the subject according to a predetermined condition, so that the quality of the captured image is better, and then a three-dimensional image is constructed based on the captured image and the depth image with better quality. So you can get the ideal 3D effect and AR experience.

In some embodiments, the main camera 30 is a wide-angle camera, and the sub-camera 40 is a telephoto camera. It should be noted that "wide-angle" and "telephoto" are relative terms. The wide-angle camera has a larger field of view relative to the telephoto camera, and the telephoto camera has a longer focal length and a longer shooting distance than the wide-angle camera.

When the processor 10 switches to a wide-angle camera to capture a captured image of the subject according to a predetermined condition, the image is a wide-angle image, and the processor 10 constructs a three-dimensional image of the subject according to the depth image and the wide-angle image; When switching to a telephoto camera to capture a captured image of the subject, the image is a telephoto image, and the processor 10 constructs a three-dimensional image of the subject according to the depth image and the telephoto image.

In the embodiment of the present application, the electronic device 100 includes a wide-angle camera and a telephoto camera at the same time. The processor 10 may switch the wide-angle camera or the telephoto camera according to the actual situation to collect the captured image of the subject, thereby constructing two different types of wide-angle and telephoto Type of three-dimensional images is conducive to improving the photographing experience.

In some embodiments, the main camera 30 is a color camera (ie, an RGB camera), and the sub camera 40 is a black and white camera (ie, a Mono camera). Compared with the color camera, the black and white camera can improve the shooting quality of low-light / night scene images.

When the processor 10 switches to collect a captured image of the subject according to a predetermined condition, the image is an RGB image, and the processor 10 constructs a three-dimensional image of the object according to the depth image and the RGB image; When the condition is switched to when the sub-camera 40 collects a captured image of the subject, the image is a Mono image, and the processor 10 constructs a three-dimensional image of the subject according to the depth image and the Mono image.

In the embodiment of the present application, the electronic device 100 includes both a color camera and a black-and-white camera. The processor 10 may switch the color camera or the black-and-white camera according to the actual situation to collect the captured image of the subject, thereby constructing two different types of three-dimensional RGB and Mono Images, which will help improve the photo experience.

Please continue to refer to FIG. 2. In some embodiments, the time-of-flight module 20 and the sub-camera 40 are respectively disposed on two sides of the main camera 30.

Since the main camera 30 is located between the time-of-flight module 20 and the sub-camera 40, on the one hand, if the processor 10 switches the main camera 30 or the sub-camera 40 according to a predetermined condition to collect a captured image of the subject, the main camera 30 and the sub-camera The parallax between 40 is small, which is helpful for achieving smooth zoom. On the other hand, users generally use more cameras as the main camera 30, that is, the processor 10 is more likely to switch to the main camera 30 to collect captured images of the subject according to predetermined conditions, so that the processor 10 When constructing a three-dimensional image of the object based on the depth image and the captured image collected by the main camera 30, the parallax between the time-of-flight module 20 and the main camera 30 is small, which is beneficial to constructing a three-dimensional image of the object.

In the embodiment of the present application, the time-of-flight module 20 and the sub-camera 40 are respectively disposed on both sides of the main camera 30, which is beneficial to achieve smooth zooming between the main camera 30 and the sub-camera 40, and is also conducive to constructing a three-dimensional object image.

Further, the centers of the time-of-flight module 20, the main camera 30, and the sub-camera 40 can be located in a straight line in order, on the one hand, the bracket 102 can be reduced along the top of the electronic device 100 (that is, Side) to the bottom (that is, the side of the electronic device 100 away from the bracket 102); on the other hand, the bracket 102 drives the time-of-flight module 20, the main camera 30, and the sub-camera 40 to move outside the casing 101 It can synchronously protrude from the casing 101 to structurally ensure that the time-of-flight module 20, the main camera 30 and the sub-camera 40 can work synchronously, saving shooting time.

Referring to FIG. 2, in some embodiments, the main camera 30 is a wide-angle camera, and the sub-camera 40 is a telephoto camera. The processor 10 may be used to execute the method in 04. The main camera 30 can be used to execute the method in 021, and the sub camera 40 can be used to execute the method in 022. That is to say, the processor 10 may be used to obtain the current distance between the subject and the electronic device 100 in real time. When the current distance is less than the distance threshold, the main camera 30 collects captured images; when the current distance is greater than or equal to the distance threshold, the sub camera 40 collects captured images.

Specifically, since the processor 10 acquires the current distance between the subject and the electronic device 100 in real time, the electronic device 100 can switch the camera used to capture the captured image in real time according to the current distance.

Assume that the distance threshold is d0. At the first moment, the processor 10 obtains the current distance between the subject and the electronic device 100 as d1, where d1 <d0. At this time, the main camera 30 collects a captured image of the subject; at the second moment, the processing The current distance between the object 10 and the electronic device 100 is d2, where d2> d0. At this time, the sub-camera 40 acquires a captured image of the object again. The final processor 10 constructs a three-dimensional image of the subject based on the depth image and the captured image collected by the sub-camera 40.

Further, when the current distance is less than the distance threshold, the main camera 30 may focus using a laser focusing mode. When the current distance is greater than or equal to the distance threshold, the sub-camera 40 may use the passive focus mode for focusing. Among them, the passive focus method includes a contrast focus mode and a phase focus mode.

In some embodiments, the step (that is, 04) of the processor 10 acquiring the current distance between the subject and the electronic device 100 in real time includes: the processor 10 continuously acquiring multiple initial values between the subject and the electronic device 100 distance. When the amount of change between the plurality of initial distances is less than a predetermined value, the processor 10 calculates a current distance between the subject and the electronic device 100 according to an average value of the plurality of initial distances, and then switches according to the calculated current distance The main camera 30 or the sub camera 40 captures a captured image of a subject.

In one embodiment, the processor 10 is configured to obtain the current distance according to the depth image.

Specifically, the time-of-flight module 20 first collects a depth image of the subject, and then obtains a current distance between the subject and the electronic device 100 according to the depth image. When the current distance is less than the distance threshold, the main camera 30 collects captured images; when the current distance is greater than or equal to the distance threshold, the sub camera 40 collects captured images of the subject.

In the embodiment of the present application, the depth image collected by the time-of-flight module 20 can be used to construct a three-dimensional image of the subject, and can also be used to detect the current distance between the subject and the electronic device 100. The electronic device 100 does not need to be set. Another distance sensor to detect the current distance is beneficial to reduce the number of components in the electronic device 100 and save costs.

In another embodiment, the electronic device 100 further includes a distance detection device 50. The distance detecting device 50 is configured to detect the current distance in real time and send it to the processor 10.

For example, the distance detection device 50 is a distance sensor, and the distance sensor directly detects the current distance between the subject and the electronic device 100. For another example, the distance detection device 50 is a structured light module. The structured light module collects a structured light image of a subject, and then detects a current distance between the subject and the electronic device 100 based on the structured light image. Of course, in other embodiments, the distance detection device 50 may be another type of detection device, and it is only required to be able to detect the current distance between the subject and the electronic device 100, such as an ultrasonic rangefinder, a radar rangefinder, Proximity sensors, etc.

In the embodiment of the present application, the distance detection device 50 can detect the current distance in advance. If the current distance is less than the distance threshold, the main camera 30 collects captured images; if the current distance is greater than or equal to the distance threshold, the sub camera 40 collects captured images. The main camera 30 or the sub-camera 40 may collect a depth image of the subject while the time-of-flight module 20 collects a captured image of the subject, so as to save time for constructing a three-dimensional image of the subject and improve a user experience. Of course, the main camera 30 or the sub-camera 40 may also capture captured images before the time-of-flight module 20 captures depth images; or capture images after the depth-of-flight module 20 captures depth images, which is not limited herein.

06: Detect face information in the preview image;

The main camera 30 or the sub camera 40 may be used to execute the method in 05, and the processor 10 may be used to execute the methods in 06 and 023. That is to say, the main camera 30 or the sub camera 40 can be used to collect a preview image of a subject. The processor 10 may be configured to detect face information in the preview image, and switch the main camera 30 or the sub-camera 40 according to the face information to capture a captured image.

In one embodiment, the face information includes the number of faces. When the number of faces is greater than a predetermined number (as shown in FIG. 5), the main camera 30 collects captured images; when the number of faces is less than or equal to a predetermined number (as shown in FIG. 6), the sub-camera 40 collects captured images.

07: Get the current brightness of the ambient light in real time;

In some embodiments, the main camera 30 is a color camera, and the sub camera 40 is a black and white camera. The processor 10 may be used to execute the method in 07, the secondary camera 40 may be used to execute the method in 024, and the main camera 30 may be used to execute the method in 025. That is to say, the processor 10 can be used to obtain the current brightness of the ambient light in real time. When the current brightness is less than the brightness threshold, the sub-camera 40 collects captured images. When the current brightness is greater than or equal to the brightness threshold, the main camera 30 captures captured images.

It can be understood that the black and white camera can improve the shooting quality of low-light / night scene images compared to the color camera. Therefore, when the current brightness is less than the brightness threshold, the captured image may be captured by the sub-camera 40; when the current brightness is greater than or equal to the brightness threshold, the captured image may be captured by the main camera 30. The processor 10 switches a color camera or a black and white camera according to the current brightness of the ambient light to capture a captured image of the subject, thereby constructing two different types of three-dimensional images, RGB and Mono, which is beneficial to improving the photographing experience.

Since the processor 10 acquires the current brightness of the ambient light in real time, the electronic device 100 can switch the camera used to capture the captured image in real time according to the current brightness. Assume that the brightness threshold is L0. At the first moment, the processor 10 obtains the current brightness of the ambient light as L1, where L1 <L0. At this time, the sub-camera 40 collects the captured image of the subject; at the second moment, the processor 10 obtains the current brightness of the ambient light. The brightness is L2, where L2> L0. At this time, the main camera 30 captures a captured image of the subject again. Finally, the processor 10 constructs a three-dimensional image of the subject based on the depth image and the captured image collected by the main camera 30.
