Detailed ways

The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used herein in the specification of the application are for the purpose of describing specific embodiments only, and are not intended to limit the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and features in the embodiments may be combined with each other without conflict.

FIG. 1 is a schematic diagram of a prior art camera. As shown in FIG. 1 , the camera includes a camera body 1 . The camera body 1 is provided with a shooting button 2 , a screen switching button 3 , a mode switching button 4 , a power button 5 , and the like.

At present, most cameras are single-screen cameras, or dual-screen cameras with a black and white screen on the front and a color screen on the back. For a single-screen camera, users often need to take selfies and take pictures, and at this time, they need to switch screens. For dual-screen cameras, the front screen is often used for basic parameters or framing display, and the rear screen is used for shooting. In this case, the user also needs to switch screens. In the above two scenarios, when the user switches between the front and rear screens, it is achieved through a separate physical button on the camera.

In addition, different shooting modes are provided in the camera for users to obtain different shooting effects. And different shooting modes also need to be switched, so when switching shooting modes, it is also achieved through a separate physical button.

For cameras, adding a physical button will increase the hardware cost, and correspondingly, the software cost will also increase. Adding physical buttons will also increase the volume of the camera. If you want not to increase the volume of the camera, you need to compress the physical space structure of the camera. Compressing the physical space structure will also cause compression of other components inside the camera.

In view of the above technical problems, the inventor of the present application proposes the following technical idea: integrate multiple control functions of the camera on one physical button, and preset the switching sequence of the multiple control functions, then after detecting the user's response to the physical button After operating the information, you can control the camera to switch the control function.

The technical solutions of the present application and how the technical solutions of the present application solve the above-mentioned technical problems will be described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

FIG. 2 is a flowchart of an embodiment of a camera control method provided by an embodiment of the present application. As shown in Figure 2, the control method of the camera may include the following steps:

Step S201 , detecting operation information of a preset button, where the preset button is used to control the camera.

FIG. 3 is a schematic diagram of an application scenario of the camera control method applicable to the embodiment of the present application. As shown in FIG. 3 , the application scenario includes: the camera body 30 ; the camera body 30 is provided with a preset button 31 ; the preset button 31 may be any button among the existing buttons on the camera body 30 .

In some embodiments, the preset button may also be set on the control device of the camera body 30; wherein, the control device may be a remote control, a handle, etc., and the user can control the camera through the remote control, handle, etc., so as to realize the above introduction several control functions.

The preset buttons in this embodiment are physical buttons, which may be physical buttons on the camera 30 or physical buttons on the control device. The camera 30 or the control device is internally provided with a controller for detecting the operation information of the physical key.

Wherein, the preset button corresponds to multiple control functions, and there is a preset switching sequence among the multiple control functions.

In some scenarios, the control function may include at least two of the following: switching from front to rear, switching from rear to front, recording mode, photo mode, time-lapse photo mode, panorama photo mode, auto exposure mode, and manual exposure model.

Step S202 , if the operation information of the preset button is detected, control the camera to switch from the current control function to another control function.

Specifically, if the operation information of the preset button is detected, according to the preset switching rule, the camera is controlled to switch from the current control function to the next control function in the switching sequence indicated by the preset switching rule.

In this embodiment, the operation information of the preset button is detected, the preset button is used to control the camera, and the preset button corresponds to multiple control functions; if the operation information of the preset button is detected, the camera is controlled to switch from the current control function to another control function. Since the preset buttons correspond to multiple control functions, it is possible to integrate multiple control functions on one physical button, and realize the switching of multiple control functions through one physical button. Switch between different control functions based on the spatial structure of other components inside the camera.

On the basis of the above embodiment, a preset time can also be set, and it is determined whether to switch the control function according to the number of key operations within the preset time range. Specifically, if the operation information of the preset button is detected within the preset time, control the camera to switch from the current control function to another control function; if the operation information of the preset button is not detected within the preset time, execute Current control function.

On the basis of the above embodiment, in this embodiment, a switching rule can be preset based on the switching sequence introduced above, so that when the operation information of the preset button is detected, the camera can be controlled from the current control according to the preset switching rule according to the preset switching rule. The function switches to the next control function indicated by the switching rule. Wherein, the handover rule is used to instruct sequential handover or skip handover based on the above-mentioned handover sequence.

In the switching rule for sequential switching, step S202 of this embodiment specifically includes: if the single operation information of the preset button is detected within the preset time, then according to the preset switching sequence of the control functions, control the camera from the current control The function switches to the next control function.

In this embodiment, if the preset switching sequence includes: control function A-control function B-control function C-...-control function N; then the switching rule of sequence switching means that every time a key operation information is detected, then Control the camera to perform a sequence switching of the control functions according to the above switching sequence. For example, if it is detected that the user has pressed the preset button once within the preset time, and the current control function is the control function A, the camera is controlled to switch from the control function A to the control function B.

In some scenarios, the control function to be switched by the user may not be adjacent to the current control function in the switching sequence. In order to meet the user's requirement in this situation, this embodiment also proposes a jump switching rule. The jump switching rules are described in detail below through specific embodiments:

In the switching rule of skip switching, step S202 of this embodiment specifically includes: if multiple operation information of the preset button is detected within the preset time, controlling the camera to switch from the current control function to another control function, and then control the camera to switch from the current control function to another control function. A control function is not adjacent to the current control function in the switching sequence, and the number of times of operating the information is related to the number of skipped control functions.

Specifically, the number of times the information is manipulated multiple times is equal to the number of skipped control functions.

For example, if the preset switching sequence includes: control function A-control function B-control function C-...-control function N; the current control function is control function A, and the user wants to switch to control function C, then The user needs to press the preset button twice within the preset time to switch to the control function C.

In order to improve the user's visual effect experience, on the display of the user graphical interface, it is possible to switch from the display screen of the current control function to the display screen of another control function. That is, the control function between the current control function and another control function in the switching sequence is not displayed. Still using the above example to illustrate, if the user presses the preset button twice within the preset time, and the current control function is control function A, the display screen of control function A is directly switched to the display screen of control function C. .

In the embodiments of sequential switching and skip switching, in order to avoid excessively long waiting time, the user experience is affected. In some examples, the preset time may be set to 2-3 seconds. Of course, the 2-3 seconds here are exemplary descriptions, and those skilled in the art can set the preset time according to actual requirements, which is not limited in this embodiment.

The switching sequence of the control functions described above can also be customized by the user. That is, the user can set the position of the control function in the switching sequence, for example, set the control function of screen switching to the second or third key response.

Specifically, the method of this embodiment further includes the steps of: acquiring adjustment information for the preset switching sequence; and adjusting the preset switching sequence according to the adjustment information for the preset switching sequence.

For example, the current switching sequence includes: control function A-control function B-control function C-...-control function N; Input the adjustment information on the display interface of the camera to place the control function C at the position of the second key response. After receiving the above adjustment information, the camera's controller will adjust the current switching sequence, and the adjusted switching sequence It is: control function A-control function C-control function B-...-control function N.
