It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 2, a flowchart illustrating steps of a photographing control method according to an embodiment of the present invention is shown, and is applied to a mobile terminal, where the mobile terminal includes a touch display screen and a camera, and the method specifically includes the following steps:
it should be noted that the mobile terminal may include various mobile devices, such as a mobile phone, a tablet computer, a PDA, and the like. The operating system of the mobile terminal may include Android (Android), IOS, Windows Phone, Windows, and the like.
The mobile terminal is generally provided with a camera, a preset icon can be contained on a user interface provided by the mobile terminal, and a user can call the camera to take a picture/shoot by clicking the preset icon or call the camera to take a picture/shoot by triggering a touch response area in a preset range of the camera.
In a touch-operable mobile terminal, a display screen and a touch screen (touch screen) may be generally included. The Display screen may Display User Interface (UI) elements, such as a window (including a control), on the screen, and specifically may include an LCD (Liquid Crystal Display) Display screen, an LED (Light-Emitting Diode) Display screen, and the like.
The touch screen may also be referred to as a "touch screen" or a "touch panel", and is an inductive liquid crystal display device capable of receiving input signals such as a contact, and may specifically include a resistive touch screen, a capacitive touch screen, and the like, which is not limited in the embodiments of the present invention.
In order to make those skilled in the art better understand the embodiments of the present invention, in the embodiments of the present invention, a capacitive technology touch screen is described as an example of a touch screen of a mobile terminal. Specifically, when a user performs a trigger operation on the mobile terminal, capacitance changes at a position of a touch area (for example, an area corresponding to a preset image capture icon) acted by the trigger operation, and the triggered touch area can be determined by measuring the change of the capacitance.
In the embodiment of the invention, when a user needs to take a picture, the triggering operation can be carried out on the preset area of the touch display screen of the mobile terminal, and after the mobile terminal receives the triggering operation acted on the preset area, the mobile terminal can respond to the triggering operation and enter the area adjusting mode.
In a preferred embodiment of the present invention, the trigger operation includes a long press operation or a double-click operation, and the trigger operation includes a touch point.
Of course, when implementing the solution of the embodiment of the present invention, a person skilled in the art may set the trigger operation as another operation according to actual requirements, for example, a triple-click operation, which is not limited in the embodiment of the present invention.
In the embodiment of the present invention, the preset area may be a touch response area of a preset icon, or the preset area is a touch response area within a preset range of the camera.
The preset icon may be a preset application icon for starting the camera application, so that the camera application can be used for shooting/photographing.
in the embodiment of the present invention, the variable region may be a preset-sized region frame, and the size and the length-width ratio of the region frame may be changed by subsequent operations. Specifically, the preset size may be the same as the size of the preset area, and the position of the variable area may be the same as the position of the preset area, that is, the variable area is displayed at the position of the preset area.
The user can adjust the size of the variable region by performing a region changing operation on the display screen of the mobile terminal.
Specifically, at least one point on the outer contour of the variable region may be a fixed point (i.e., a point whose position does not change) with which the variable region is expanded toward the direction of the region changing operation when the size of the variable region is adjusted. In this case, the variable region may be rectangular, and when the size of the variable region is adjusted, the variable region may be expanded in a rectangular manner.
Of course, when implementing the embodiment of the present invention, a person skilled in the art may set the shape of the variable region according to actual requirements, for example, the shape of the variable region is a diamond shape, an oval shape, and the like, which is not limited by the embodiment of the present invention.
It should be noted that, when the variable region is located at the middle position of the mobile terminal, when the size of the variable region is adjusted, the variable region may be expanded around the position corresponding to the variable region as a starting point, which is not limited in the embodiment of the present invention.
In a preferred embodiment of the present invention, the preset icon may be located at an edge position such as the upper left corner, the upper right corner, the lower left corner or the lower right corner of the user interface of the mobile terminal.
The position of the variable area is consistent with that of the preset area, and the preset area is arranged at the edge position of the user interface of the mobile terminal, so that the variable area can be located at the edge position, and a user can conveniently determine the target area according to the variable area.
In another preferred embodiment of the present invention, the touch display screen of the mobile terminal includes a camera hole, and the preset area at least partially includes the camera hole.
As shown in fig. 3, which is a schematic diagram of a camera hole digging of the present invention, in fig. 3, a mobile terminal includes a camera hole digging, and the camera hole digging is located at the upper left corner of the mobile terminal, and then a preset area coinciding with the position of the camera hole digging is also located at the upper left corner of the mobile terminal.
In a specific implementation, the size of the preset area may be slightly larger than the diameter of the camera hole, for example, the size of the preset area is 4px larger than the diameter of the camera hole. The px is a pixel unit, and when the size of the preset area is calculated, a pixel value corresponding to the diameter of the camera hole in the mobile terminal can be obtained first, so that the size of the preset area is determined.
As shown in fig. 4, which is a schematic diagram illustrating a variable area of the present invention, in fig. 4, a mobile terminal is provided with a camera hole, a position of a preset area coincides with a position of the camera hole, and when a trigger operation acting on the preset area is received, a position of a variable area provided also coincides with the position of the camera hole.
In a preferred embodiment of the present invention, the region changing operation includes a sliding operation, and the step 202 may include the following sub-steps:
and receiving a sliding operation acted on a display screen of the mobile terminal, and stretching the variable area.
The user may perform a sliding operation on the display screen of the mobile terminal, and the mobile terminal detects the sliding operation applied to the display screen of the mobile terminal and stretches the variable region according to the sliding operation. Specifically, the sliding operation may have a sliding direction and a sliding distance, and the mobile terminal stretches the variable region according to the sliding direction and the sliding distance of the sliding operation.
As shown in fig. 5, which is a schematic diagram illustrating a sliding operation of the present invention, in fig. 5, the variable region is located at the upper left corner of the mobile terminal, and the sliding direction of the sliding operation acting on the display screen of the mobile terminal is a direction from the position of the variable region to the lower right corner, and then the variable region is stretched from the position of the variable region to the lower right corner.
As shown in fig. 6, which is a schematic diagram illustrating another sliding operation of the present invention, in fig. 6, a mobile terminal is displayed on a horizontal screen, a variable region is located at a lower left corner of the mobile terminal, and a sliding direction of the sliding operation acting on a display screen of the mobile terminal is a direction from a position of the variable region to an upper right corner, and the variable region is stretched from the position of the variable region to the upper right corner.
In another preferred embodiment of the present invention, the region changing operation includes a target point triggering operation, and the step 202 may include the following sub-steps:
responding to a target point trigger operation acting on a display screen of the mobile terminal, and determining a target point; and adjusting the size of the variable area by adopting the target point.
The user can also change the size of the variable region by performing a target point triggering operation on the display screen of the mobile terminal. The target point triggering operation may be a click operation, a double-click operation, a triple-click operation, or the like, and when the mobile terminal detects the target point triggering operation, a position corresponding to the target point triggering operation may be determined.
For example, when the display screen of the mobile terminal is a capacitive touch screen, and a user performs a target point triggering operation on the display screen of the mobile terminal, a capacitance change occurs at a position of a touch point (i.e., a target point) acted by the target point triggering operation, and the triggered touch point (i.e., the target point) can be determined by measuring the capacitance change.
In the embodiment of the invention, when the mobile terminal detects the target point trigger operation acting on the display screen of the mobile terminal, the target point can be determined, and the size of the variable area is changed by taking the positions of the target point and the variable area as two endpoints, so that the target area is determined.
It should be noted that the position of the variable region may be the position of the upper left corner, the lower left corner, the upper right corner, and the lower right corner of the variable region, and when the embodiment of the present invention is implemented, the position of the variable region may be set according to actual needs, for example, when the target point is located at the lower right corner, the position of the variable region is the upper left corner of the variable region, which is not limited in the embodiment of the present invention.
the area determination operation may be an operation in which the sliding operation ends, or an operation in which the target point trigger operation ends.
In the embodiment of the present invention, when the mobile terminal detects that the sliding operation is ended, the variable region after stretching may be determined as the target region by the response region determination operation (operation of ending the sliding operation). As an example, the sliding operation ending may be that when it is detected that the finger (or other trigger) of the user leaves the display screen of the mobile terminal, the sliding operation is considered to be ended (area determination operation), and at this time, the stretched variable area may be determined to be the target area.
In the embodiment of the present invention, when the area changing operation is the target point triggering operation, a time threshold may be set, and the target point triggering operation is considered to be ended from the time when the target point triggering operation is detected until the time threshold is ended, and at this time, the target area may be determined in response to an operation (area determining operation) in which the target point triggering operation is ended.
Specifically, when only one click operation (area change operation) is performed within the time threshold, the trigger point corresponding to the click operation (area change operation) is used as the target point, and the target area is determined; when there are a plurality of click operations (area change operations) within the time threshold, the target area may be determined with the trigger point corresponding to the last click operation (area change operation) as the target point.
the preset threshold may be a preset size threshold. The preset threshold may be a minimum size that can receive a user operation between the target areas.
The preset condition may be a condition of a displacement length of the sliding operation, or the preset condition may be a condition of a connection length between the touch point and the target point.
In the embodiment of the present invention, whether a photographing interface needs to be provided may be determined by determining whether the size of the variable region reaches a preset threshold, or determining whether the region changing operation satisfies a preset condition. Specifically, when the region changing operation is a sliding operation, it may be determined whether the size of the target region reaches a preset threshold, or whether the sliding operation satisfies a condition of a displacement length of the sliding operation; when the area changing operation is a click operation, it may be determined whether the size of the target area reaches a preset threshold, or whether the click operation satisfies a condition of a connection line length between the touch point and the target point.
In the embodiment of the present invention, when the size of the variable region reaches the preset threshold, or when the region changing operation satisfies the preset condition, a photographing interface may be provided.
In specific implementation, it is considered that if the provided photographing area is too small, some photographing controls are likely to be difficult to display and click, the definition of the photo is not enough, and the like, so that the photographing effect is affected, therefore, a preset threshold or a preset condition can be set, and when the size of the target area reaches the preset threshold or the preset condition, a photographing interface is provided, so that a user can directly perform photographing operation on the photographing interface.
In a preferred embodiment of the present invention, the preset threshold may be determined by:
acquiring the size of a display screen of the mobile terminal; calculating the product of the size of the display screen and a preset ratio; and determining the preset threshold value by adopting the product.
The preset ratio may be a preset screen occupation ratio for indicating a ratio of the size of the target area to the size of the display screen of the mobile terminal. For example, the preset ratio may be 1/3, or 1/4.
In the embodiment of the invention, the preset threshold value can be determined by obtaining the size of the display screen of the mobile terminal and calculating the product of the size of the display screen and the preset ratio.
In the embodiment of the present invention, the photographing region may be determined in the photographing interface according to the target region, specifically, the size of the photographing region may be determined to be consistent with the size of the target region, and the position of the photographing region may be determined to be consistent with the position of the target region or centered on the display screen of the corresponding mobile terminal.
In the provided photographing interface, the size of the photographing region is consistent with that of the target region, namely the size of the photographing region can be obtained by adjusting the size of the variable region, so that the size of the photographing region can be flexibly set when photographing.
The camera interface may include buttons for taking a picture, such as a picture button, a camera toggle button, and the like. Of course, when implementing the embodiment of the present invention, a person skilled in the art may also set a photographing interface including other buttons according to actual needs, for example, a filter switching button, which may be used to implement switching of a filter effect, and the embodiment of the present invention is not limited thereto.
Referring to fig. 7A to 7C, which are schematic diagrams illustrating a photographing interface according to the present invention, in fig. 7A to 7C, a photographing interface including a photographing region having a size corresponding to a size of a target region is provided on a mobile terminal.
In the embodiment of the invention, after the photographing interface is provided on the mobile terminal, the sliding operation can be further performed on the display screen of the mobile terminal, so that the size of the photographing area is further changed, the real-time change of the size of the photographing area is realized, and the user experience is improved.
In a preferred embodiment of the present invention, the method may further comprise the steps of:
and responding to the photographing operation, acquiring an initial image through the camera, and determining a photographed image according to the photographing region and the initial image.
Specifically, the photographing operation may be an operation of clicking a photographing button in the photographing interface, or an operation of pressing a preset key of the mobile terminal. When the photographing operation is received, the initial image can be obtained through the camera in response to the photographing operation, and the photographed image is determined according to the photographing region and the initial image.
If the size of the photographed image can be consistent with the size of the photographed area, the photographed image is determined according to the photographed area and the initial image, and the photographed image can be a photographed image which is consistent with the size of the photographed area in the initial image captured according to the size of the photographed area.
In a preferred embodiment of the present invention, the method may further comprise the steps of:
and when the size of the target area does not reach a preset threshold value or when the area changing operation does not meet a preset condition, responding to the end of the area changing operation and exiting the area adjusting mode.
