Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

The present invention provides a variety of solutions for the problem of unnatural switching during the use of split-type dual cameras in the prior art, specifically as follows:

Embodiment one

As shown in FIG. 1, the camera switching method provided by Embodiment 1 of the present invention includes:

Step 11: Obtain the zoom ratio of the first camera currently activated by the terminal in real time.

The first camera may be a wide-angle camera or a telephoto camera; the zoom ratio refers to a change ratio of an image currently acquired by the first camera relative to an image acquired when the first camera is just turned on. The magnification of the image captured by the first camera can be changed according to the instruction input by the user. The user adjusts the zoom ratio by stretching the control, or by pinching or pinching two fingers on the viewfinder screen, or by inputting zoom ratio commands through other gestures.

Step 12: When the zoom ratio reaches a ratio threshold, switch from the first camera to the second camera.

After the first viewfinder image is enlarged by a preset multiple, or when the first viewfinder image starts to be reduced, it is determined whether the zoom ratio of the first viewfinder image reaches a magnification threshold. The preset multiple may be 2.3 times.

Correspondingly, the second camera may be a telephoto camera or a wide-angle camera.

Wherein, the viewing range of the first camera is different from that of the second camera, and the viewing range of the first camera includes or is included in the viewing range of the second camera; The second camera is two independent cameras arranged on the same side of the housing of the terminal. That is, the solution of the embodiment of the present invention is mainly aimed at the split camera.

In order to facilitate the second camera to load various parameters and prevent the second camera from being restarted when the zoom ratio reaches the magnification threshold, a short black screen will appear on the viewfinder screen due to loading problems, which will reduce user experience; Before the second camera, the method further includes: starting the second camera when the difference between the zoom ratio and the ratio threshold is smaller than a predetermined value. The second camera runs in the background, and will load the corresponding parameters after startup, so that when the zoom ratio reaches the ratio threshold, it can complete coherent switching and avoid black screen.

That is, when the viewfinder range of the current first viewfinder picture is approaching the viewfinder range of the second viewfinder picture of the second camera, and is approaching the viewfinder range of the second viewfinder picture, the second camera is activated in the background.

Wherein, the zoom ratio can be reflected by the viewfinder screen, and correspondingly, the step of acquiring the zoom ratio of the first camera currently activated by the terminal in real time includes: acquiring the first viewfinder screen of the first camera in real time; When the magnification reaches the magnification threshold, the step of switching from the first camera to the second camera includes: when the first viewing image overlaps with the second viewing image of the second camera of the terminal, switching from the first camera Switch to the second camera.

Here, the overlapping of the first viewfinder picture with the second viewfinder picture of the second camera of the terminal means that the first viewfinder picture can overlap with the second viewfinder picture of the second camera.

The above determination of whether the zoom ratio of the first viewfinder picture reaches the magnification threshold may also be expressed as judging whether the first viewfinder picture overlaps with the second viewfinder picture of the second camera of the terminal.

Specifically, when the first framing picture overlaps with the second framing picture of the second camera of the terminal, the step of switching from the first camera to the second camera includes: Switching from the first camera to the second camera when the pixels of the first preset border critical point of the frame overlap with the pixels of the second preset border critical point of the second viewing frame.

That is, the pixels at the border critical points of the framing screen are used to determine whether it is necessary to switch cameras.

Considering that there is a certain error in the installation of the split camera, when the pixels of the first preset boundary critical point of the first viewfinder picture overlap with the pixels of the second preset boundary critical point of the second viewfinder picture, The step of switching from the first camera to the second camera includes:

When the pixels of the left and right boundary critical points of the first viewfinder picture overlap with the pixels of the left and right boundary critical points of the second viewfinder picture, or, when the pixels of the upper and lower boundary critical points of the first viewfinder picture overlap with the Switching from the first camera to the second camera when the pixels at the critical points of the upper and lower borders of the second viewfinder frame overlap.

That is to say, for the critical point judgment this time, only the upper and lower boundaries or the left and right boundaries need to meet the conditions.

Optionally, the number of pixels of each boundary critical point is 10.

Considering that the two cameras in the split camera have a certain position difference when they are installed, there will be a certain position jump when switching cameras, so in the embodiment of the present invention, switching from the first camera to the When the second camera is described, it also includes: performing blur animation processing on the process of switching from the first viewfinder picture of the first camera to the second viewfinder picture of the second camera; thereby improving user experience.

Specifically, the first camera is a wide-angle camera, and the second camera is a telephoto camera. Correspondingly, the viewing range of the first camera is larger than and includes the viewing range of the second camera, and the zoom ratio is magnification; or,

The first camera is a telephoto camera, and the second camera is a wide-angle camera. Correspondingly, the viewing range of the first camera is smaller than and included in the viewing range of the second camera, and the zoom ratio is a reduction ratio .

The camera switching method provided in Embodiment 1 of the present invention will be further described below.

As shown in Figure 2, the viewing angle of the wide-angle camera in the general split camera is 90 degrees, and the viewing angle of the telephoto camera is 37 degrees, that is, the viewing range of the wide-angle camera is much larger than that of the telephoto camera. The viewfinder picture of the telephoto camera completely overlaps the viewfinder range of the wide-angle camera, so, according to this, the embodiment of the present invention provides a switching method that enables the two cameras to switch naturally, as follows:

Switch from wide-angle camera to telephoto camera:

The default viewfinder of the existing camera interface is the viewfinder range of the wide-angle camera, while the viewfinder range of the telephoto camera is smaller than that of the wide-angle camera and completely overlaps with the viewfinder range of the wide-angle camera. Scheduled operation) Zoom in on the screen. When the framing screen is magnified to 2.3 times, start looking for the critical point of screen overlap. Take the current framing screen as the judgment reference, and compare the framing screen of the telephoto camera with 10 pixels at the top, bottom, left, and right. point, or the pixel points of the left and right critical points (because there are certain errors in the installation of the split camera, so the judgment of the critical point this time only needs to meet one of the conditions of up and down or left and right), and the viewfinder of the telephoto camera When the upper and lower critical points of the screen, or the pixels of the left and right critical points overlap completely, it will automatically switch to the telephoto camera. Because there is a certain position difference between the two cameras when they are installed, there will be a certain position jump when switching cameras Therefore, when the camera is switched here, there needs to be a blur animation transition.

Telephoto camera switches to wide-angle camera:

In the camera interface, when viewing the view with the telephoto camera, pinch with two fingers (the second scheduled operation such as sliding two contact points towards each other) to zoom out the screen, and start looking for the critical point where the screen overlaps. Based on the current viewfinder screen, 10 pixels up, down, left, and right are used for comparison. The framing screen of the wide-angle camera is at the upper and lower critical points, or at the pixel points of the left and right critical points (because there is a certain error in the installation of the split camera, so the judgment of the critical point this time only needs to be up and down or left and right, and one of the conditions is met. Yes), when the pixels completely overlap with the upper and lower critical points of the viewfinder screen of the wide-angle camera, or the pixels of the left and right critical points, it will automatically switch to the wide-angle camera. Because there is a certain position difference between the two cameras when they are installed, when switching cameras, There will be a certain position jump, so when the camera is switched here, a blur animation transition is required.

It can be seen from the above that the present invention adopts a split-type dual camera, and a wide-angle camera and a telephoto camera are installed at the rear. The two cameras are installed independently, which can make the terminal thinner; at the same time, the two cameras operate independently to realize close-up and long-range viewing. Switching, interactively zooming in on the viewfinder frame and the original zooming in on the viewfinder, except for the transition animation, there is no difference in appearance (to the user) in terms of interaction. Naturally switch to another camera, simulating optical zoom, allowing users to take close-up shots or long-range shots Can have a clear imaging effect.

To sum up, the camera switching method provided in Embodiment 1 of the present invention determines whether the wide-angle camera and the telephoto camera have different viewfinder ranges, and the viewfinder range of the telephoto camera completely overlaps with the viewfinder range of the wide-angle camera. The critical point where the framing screen of the camera overlaps with the framing screen of the telephoto camera quickly switches between the wide-angle camera and the telephoto camera, simulates optical zoom, and interacts naturally, which solves the problem of unnatural switching during the use of split dual cameras in the prior art.

The obtaining module 31 is configured to obtain the zoom ratio of the first camera currently activated by the terminal in real time.

The first camera may be a wide-angle camera or a telephoto camera; the zoom ratio refers to a change ratio of an image currently acquired by the first camera relative to an image acquired when the first camera is just turned on. The magnification of the image captured by the first camera can be changed according to the instruction input by the user. The user adjusts the zoom ratio by stretching the control, or by pinching or pinching two fingers on the viewfinder screen, or by inputting zoom ratio commands through other gestures.

A switching module 32, configured to switch from the first camera to the second camera when the zoom ratio reaches a ratio threshold.

Wherein, the viewing range of the first camera is different from that of the second camera, and the viewing range of the first camera includes or is included in the viewing range of the second camera; The second camera is two independent cameras arranged on the same side of the housing of the terminal. That is, the solution of the embodiment of the present invention is mainly aimed at the split camera.

The second camera runs in the background, and will load the corresponding parameters after startup, so that when the zoom ratio reaches the ratio threshold, it can complete coherent switching and avoid black screen.

That is, the activation module activates the second camera when the viewfinder range of the current first viewfinder picture is approaching the viewfinder range of the second viewfinder picture of the second camera, and is approaching the viewfinder range of the second viewfinder picture.

Wherein, the zoom ratio can be reflected by the viewfinder picture, and correspondingly, the acquisition module includes: an acquisition submodule for acquiring the first viewfinder picture of the first camera in real time; the switching module includes: a switch submodule for When the first viewing image overlaps with the second viewing image of the second camera of the terminal, switching from the first camera to the second camera.

Here, the overlapping of the first viewfinder picture with the second viewfinder picture of the second camera of the terminal means that the first viewfinder picture can overlap with the second viewfinder picture of the second camera.

The above determination of whether the zoom ratio of the first viewfinder picture reaches the magnification threshold may also be expressed as judging whether the first viewfinder picture overlaps with the second viewfinder picture of the second camera of the terminal.

Specifically, the switching sub-module includes: a switching unit, configured to overlap pixels at a first preset boundary critical point of the first viewfinder picture with pixels at a second preset boundary critical point of the second viewfinder picture , switch from the first camera to the second camera.

That is, the first processing module judges whether it is necessary to switch the camera by using the pixels of the boundary critical point of the viewfinder picture.

Considering that there is a certain error in the installation of the split-type camera, the switching unit includes: a switching subunit, which is used to connect the pixels at the left and right boundary critical points of the first viewfinder picture to the left and right borders of the second viewfinder picture. When the pixels of the points overlap, or when the pixels of the upper and lower boundary critical points of the first viewfinder picture overlap with the pixels of the upper and lower boundary critical points of the second viewfinder picture, switch from the first camera to the second Second camera.

That is to say, for the critical point judgment this time, only the upper and lower boundaries or the left and right boundaries need to meet the conditions.
