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.
The embodiment of the invention provides a flash lamp adjusting method and a user terminal. Thereby the flash lamp can be conveniently adjusted.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a method for adjusting a flash lamp according to an embodiment of the present invention. The method shown in fig. 1 may be applied to a user terminal equipped with a flash lamp, such as a smart phone (e.g., an Android phone, an iOS phone, etc.), a tablet computer, a palmtop computer, a Mobile Internet Device (MID), a PAD, etc. As shown in fig. 1, the flash lamp adjusting method may include the steps of:
s101, detecting whether touch operation occurs on the touch screen.
In the embodiment of the invention, the touch operation can be divided into different types of touch operation according to different classification modes. For example, the touch operation can be divided into a click operation and a slide operation according to the length of the touch time. The click operation mainly includes a touch operation with a touch duration smaller than a preset time threshold, and the slide operation mainly includes a touch operation with a touch duration larger than a preset time threshold. The setting of the time threshold can be set by the user according to needs, such as 1 second, 2 seconds, 3 seconds and the like. For another example, the touch operation can be divided into a light touch operation and a heavy touch operation according to the touch pressure value of the touch operation. The light touch operation mainly comprises a touch operation of which the touch pressure value is smaller than a preset pressure threshold; the re-touch operation mainly comprises a touch operation of which the touch pressure value is greater than a preset pressure threshold value. The pressure threshold may also be set by the user as desired, such as 0.1N, 0.2N, 0.3N, etc.
S102, if the touch operation on the touch screen is detected, obtaining touch parameters of the touch operation.
In the embodiment of the invention, if the touch operation of the touch screen is detected, the touch parameter of the touch operation can be acquired. The touch parameter may include at least one of a trigger position (e.g., a position where a finger contacts the touch screen), a touch duration, a touch direction, a touch trajectory, and the like of the touch operation, besides the touch pressure value.
S103, detecting whether the touch pressure value falls into a preset touch pressure value range.
In the embodiment of the invention, the touch pressure value range can be preset in the user terminal. The touch pressure value range may include at least one subset, that is, the touch pressure value range with a large pressure value difference includes the touch pressure value range with a small pressure value difference. For example, when the touch pressure value range with a large pressure value difference is 0.1N to 1N, the pressure value difference is 0.9N; the touch pressure value range may be divided into a plurality of subsets, for example, 0.1N to 0.3N is a first subset, 0.3N to 0.8N is a second subset, and 0.8N to 1N is a third subset.
In the embodiment of the present invention, the setting of the range of the touch pressure value may be performed by the user as needed, or may be performed by the user terminal according to a history setting record of the user, or may be performed by the user terminal according to an average value of the touch pressure values when the user inputs the touch operation.
In the embodiment of the present invention, when the user terminal sets the touch pressure range according to the average value of the touch pressure values when the user inputs the touch operation, the method may include the following steps:
11) acquiring a touch pressure value of each touch operation in a preset time period, which is stored in a user terminal;
12) determining an average value of touch pressure values in the preset time period;
13) and setting the touch pressure range to be in a range matched with the average value according to a preset setting rule.
For example, when the touch pressure values of the touch operation input by the user in one day are 0.2N, 0.3N, 0.5N, and 0.2N, and the average value of the corresponding touch pressure values is 0.3N, then (0.3+ N) N or (0.3-N) N may be set as the touch pressure range, where N is a natural number greater than 0.
And S104, if so, acquiring a brightness value corresponding to the touch pressure value range from the mapping relation between the preset pressure value range and the brightness value.
In the embodiment of the invention, the mapping relation between the preset pressure value range and the brightness value can be realized in the user terminal. The mapping relationship is mainly used to describe the corresponding relationship between the pressure value range and the brightness value, that is, different pressure value ranges correspond to different brightness values.
In the embodiment of the invention, the mapping relation between the preset pressure value range and the brightness value can be set by a user according to needs, or can be set by a user terminal according to the historical setting record of the user; the invention is not limited.
In the embodiment of the present invention, if it is detected that the touch pressure value falls within the preset touch pressure value range, the luminance value corresponding to the touch pressure value range may be obtained from the mapping relationship between the preset touch pressure value range and the luminance value, where the luminance values corresponding to different touch pressure value ranges are different.
And S105, adjusting the brightness value of the flash lamp to a brightness value corresponding to the touch pressure value range.
In the embodiment of the present invention, after the luminance value corresponding to the touch pressure value range is obtained from the mapping relationship between the preset pressure value range and the luminance value, the luminance value of the flash lamp may be adjusted to the luminance value corresponding to the touch pressure value range.
In fig. 1, after detecting that a touch operation occurs on a touch screen, a user terminal may obtain a touch parameter of the touch operation, where the touch parameter includes a touch pressure value; detecting whether the touch pressure value falls into a preset touch pressure value range or not; if yes, obtaining a brightness value corresponding to the touch pressure value range from a mapping relation between a preset pressure value range and the brightness value, wherein the brightness values corresponding to different touch pressure value ranges are different; and finally, adjusting the brightness value of the flash lamp to a brightness value corresponding to the touch pressure value range. In the embodiment of the invention, when the user needs to adjust the brightness value of the flash lamp, the user does not need to click the brightness adjusting key for adjustment, and the user only needs to input touch operation on the touch screen to adjust the flash lamp. Thereby the flash lamp can be conveniently adjusted.
Referring to fig. 2, fig. 2 is a schematic flow chart of another flash lamp adjusting method according to an embodiment of the present invention, and as shown in fig. 2, the flash lamp adjusting method may include the following steps:
s201, acquiring a current environment brightness value.
In the embodiment of the invention, before detecting whether the touch operation occurs on the touch screen, whether the state of the flash lamp is in an on state or not is also detected. The flash lamp can be turned on by a user by inputting a touch instruction, or the user terminal determines whether the flash lamp needs to be turned on according to the current environment brightness value. For example, when the current ambient brightness value is high, the shooting effect may be deteriorated when the flash is turned on. Therefore, when the ambient brightness value is high, the flash lamp is not automatically turned on.
S202, detecting whether the current environment brightness value is lower than a preset brightness threshold value.
In the embodiment of the invention, the brightness threshold value can be preset in the user terminal. The setting of the brightness threshold may be performed by the user as needed, or may be performed by the user terminal according to a history setting record of the user, or may be an optimal brightness threshold acquired by the user terminal from a large database.
In the embodiment of the invention, after the current environment brightness value is obtained, whether the current environment brightness value is lower than the preset brightness threshold value or not can be detected.
And S203, if the current environment brightness value is lower than the preset brightness threshold value, starting a flash lamp.
In the embodiment of the invention, if the current environment brightness value is detected to be lower than the preset brightness threshold, which indicates that the current environment brightness value is lower, the shooting quality in a low-light environment can be improved by starting the flash lamp.
In the embodiment of the present invention, after the flash is turned on, before the step of detecting whether the target touch operation occurs on the touch screen is executed, the method may further include the following steps:
21) acquiring the brightness value of a current flash lamp;
22) detecting whether the current flashlight brightness value is matched with the current environment brightness value or not according to the mapping relation between the preset environment brightness value and the flashlight brightness value;
23) and if the current flash lamp brightness value is detected to be not matched with the current environment brightness value, prompting to input touch operation.
In the embodiment of the invention, the mapping relation between the environment brightness value and the flash lamp brightness value can be preset in the user terminal. The mapping relationship is mainly used for describing the corresponding relationship between the environment brightness value and the flash lamp brightness value. That is, the brightness values of the flash lamps corresponding to different ambient brightness values are different.
In the embodiment of the invention, the mapping relation between the environment brightness value and the flash lamp brightness value can be set by a user according to needs, or can be set by a user terminal according to the historical setting record of the user; the invention is not limited.
In the embodiment of the invention, after the flash lamp is started, whether the current flash lamp brightness value is matched with the current environment brightness value can be detected according to the mapping relation between the preset environment brightness value and the flash lamp brightness value; if the brightness value of the flash lamp is matched with the brightness value of the flash lamp, the brightness value of the flash lamp does not need to be adjusted. If not, the input of touch operation can be prompted.
And S204, detecting whether touch operation occurs on the touch screen.
S205, if the touch operation on the touch screen is detected, acquiring the touch parameter of the touch operation.
In this embodiment of the present invention, the touch parameter may further include at least one of a trigger position (e.g., a position where a finger contacts the touch screen), a touch duration, a touch direction, a touch trajectory, and the like of the touch operation, besides the touch pressure value, which is not limited in the embodiment of the present invention.
And S206, if the touch pressure value is detected to fall into the preset touch pressure value range, acquiring a brightness value corresponding to the touch pressure value range from the mapping relation between the preset pressure value range and the brightness value.
In the embodiment of the invention, the corresponding brightness values of different touch pressure value ranges are different. When the detected touch pressure value falls into the preset touch pressure value range, the brightness value corresponding to the touch pressure value range is obtained from the mapping relation between the preset pressure value range and the brightness value.
And S207, adjusting the brightness value of the flash lamp to a brightness value corresponding to the touch pressure value range.
In the embodiment of the invention, after the brightness value corresponding to the touch pressure value range is obtained, the brightness value of the flash lamp can be adjusted to the brightness value corresponding to the touch pressure value range.
As an alternative embodiment, after the brightness value of the flash is adjusted, the camera may be controlled to rotate, so that the flash may flash with the shooting object as a reference center. Wherein controlling the flash to rotate may include:
31) acquiring a rotation angle corresponding to a touch pressure value range from a preset mapping relation between the touch pressure value range and an angle, and determining a target rotation direction corresponding to a target touch direction from the preset mapping relation between the touch direction and the rotation direction, wherein the angles corresponding to different touch pressure value ranges are different;
32) and controlling the flash lamp to rotate along the target rotation direction by the rotation angle.
In the embodiment of the invention, the mapping relation between the pressure value range and the angle can be preset in the user terminal, wherein the mapping relation between the pressure value range and the angle is mainly used for describing the mapping relation between the pressure value range and the angle. That is, the angles corresponding to different pressure value ranges are different. For example, when 0.1N to 0.3N is the first pressure value range, 0.3N to 0.8N is the second pressure value range, and 0.8N to 1N is the third pressure value range, wherein the angle corresponding to the 0.1N to 0.3N is 5 degrees, the angle corresponding to the 0.3N to 0.8N is 10 degrees, and the angle corresponding to the 0.8N to 1N is 15 degrees.
In the embodiment of the invention, the mapping relation between the pressure value range and the angle can be set by a user according to needs, or can be set by a user terminal according to the historical setting record of the user; the invention is not limited.
In the embodiment of the present invention, a mapping relationship between the touch direction and the rotation direction may also be preset in the user terminal. The mapping relationship between the touch direction and the rotation direction is mainly used for describing the corresponding relationship between the touch direction and the rotation direction, that is, the rotation directions corresponding to different touch directions are different. For example, when the touch direction is the first direction, the corresponding rotation direction may also be the first direction; when the touch direction is the second direction, the corresponding rotation direction is the second direction. The first direction and the second direction are opposite directions.
In the embodiment of the present invention, the preset mapping relationship between the touch direction and the rotation direction may be set by the user as needed, or may be set by the user terminal according to a history setting record of the user; the invention is not limited.
In the embodiment of the present invention, after the rotation angle corresponding to the touch pressure value range is obtained from the mapping relationship between the preset pressure value range and the angle, and the target rotation direction corresponding to the target touch direction is determined from the mapping relationship between the preset touch direction and the rotation direction, the flash lamp may be controlled to rotate along the target rotation direction by the rotation angle. For example, when the rotation angle corresponding to the touch pressure value range is 10 degrees obtained from the mapping relationship between the preset pressure value range and the angle, and the target rotation direction corresponding to the target touch direction is determined to be the first direction from the mapping relationship between the preset touch direction and the rotation direction, the flash lamp may be controlled to rotate 10 degrees along the first direction.
As another alternative, after adjusting the brightness value of the flash, the camera may be controlled to rotate, so that the flash may flash with the photographic subject as a reference center. Wherein controlling the flash to rotate may include:
41) acquiring a rotating speed corresponding to a touch pressure value from a mapping relation between a preset pressure value range and the speed, and acquiring a target rotating direction corresponding to a target touch direction from the mapping relation between the touch direction and the rotating direction;
42) and controlling the flash lamp to rotate according to the rotating speed and the target rotating direction.
In the embodiment of the invention, the mapping relation between the pressure value range and the speed can be preset in the user terminal. The mapping relationship between the pressure value range and the speed is mainly used for describing the mapping relationship between the pressure value range and the speed, that is, the speeds corresponding to different pressure value ranges are different. For example, when 0.1N to 0.3N is the first pressure value range, 0.3N to 0.8N is the second pressure value range, and 0.8N to 1N is the third pressure value range, wherein 0.1N to 0.3N is the speed corresponding to the first pressure value range and is 0.01m \ s, 0.3N to 0.8N is the speed corresponding to the second pressure value range and is 0.02m \ s, and 0.8N to 1N is the speed corresponding to the third pressure value range and is 0.03m \ s.
In the embodiment of the present invention, a mapping relationship between the touch direction and the rotation direction may also be preset in the user terminal. The mapping relationship between the touch direction and the rotation direction is mainly used for describing the corresponding relationship between the touch direction and the rotation direction, that is, the rotation directions corresponding to different touch directions are different. For example, when the touch direction is the first direction, the corresponding rotation direction may also be the first direction; when the touch direction is the second direction, the corresponding rotation direction is the second direction. The first direction and the second direction are opposite directions.
In the embodiment of the invention, when the rotation speed corresponding to the touch pressure value is obtained from the mapping relation between the preset pressure value range and the speed, and the target rotation direction corresponding to the target touch direction is obtained from the mapping relation between the touch direction and the rotation direction; the flash may be controlled to rotate according to the rotation speed and the target rotation direction. For example, when the rotation speed 0.02m \ s corresponding to the touch pressure value is obtained from the mapping relationship between the preset pressure value range and the speed, and when the target rotation direction corresponding to the target touch direction is determined to be the first direction from the mapping relationship between the preset touch direction and the rotation direction, the flash lamp can be controlled to rotate towards the first direction at the rotation speed of 0.02m \ s.
In fig. 2, it is detailed that after the brightness value of the flash is adjusted, the flash can be controlled to rotate, so that the flexibility of the terminal can be further increased. In the embodiment of the invention, when a user needs to adjust the brightness value of the flash lamp and control the flash lamp to rotate, the user does not need to click a fixed key for adjustment, and the user only needs to input touch operation on the touch screen for control. Thereby increasing convenience of the user terminal.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a user terminal according to an embodiment of the present invention, configured to execute the method for adjusting a flash. The user terminal shown in fig. 3 may include, but is not limited to, a smart phone (such as an Android phone, an iOS phone, etc.), a tablet computer, a palmtop computer, a Mobile Internet Device (MID), a PAD, and other user terminals equipped with a flash lamp.

the first detecting unit 301 is configured to detect whether a touch operation occurs on the touch screen.
In the embodiment of the invention, the touch operation can be divided into different types of touch operation according to different classification modes. For example, the touch operation can be divided into a click operation and a slide operation according to the length of the touch time. The click operation mainly includes a touch operation with a touch duration smaller than a preset time threshold, and the slide operation mainly includes a touch operation with a touch duration larger than a preset time threshold. The setting of the time threshold can be set by the user according to needs, such as 1 second, 2 seconds, 3 seconds and the like. For another example, the touch operation can be divided into a light touch operation and a heavy touch operation according to the touch pressure value of the touch operation. The light touch operation mainly comprises a touch operation of which the touch pressure value is smaller than a preset pressure threshold; the re-touch operation mainly comprises a touch operation of which the touch pressure value is greater than a preset pressure threshold value. The pressure threshold may also be set by the user as desired, such as 0.1N, 0.2N, 0.3N, etc.
The first obtaining unit 302 is configured to obtain a touch parameter of the touch operation if the first detecting unit 301 detects that the touch operation occurs on the touch screen, where the touch parameter includes a touch pressure value.
In the embodiment of the invention, if the touch operation of the touch screen is detected, the touch parameter of the touch operation can be acquired. The touch parameter may include at least one of a trigger position (e.g., a position where a finger contacts the touch screen), a touch duration, a touch direction, a touch trajectory, and the like of the touch operation, besides the touch pressure value.
The second detecting unit 303 is configured to detect whether the touch pressure value falls within a preset touch pressure value range.
In the embodiment of the invention, the touch pressure value range can be preset in the user terminal. The touch pressure value range may include at least one subset, that is, the touch pressure value range with a large pressure value difference includes the touch pressure value range with a small pressure value difference. For example, when the touch pressure value range with a large pressure value difference is 0.1N to 1N, the pressure value difference is 0.9N; the touch pressure value range may be divided into a plurality of subsets, for example, 0.1N to 0.3N is a first subset, 0.3N to 0.8N is a second subset, and 0.8N to 1N is a third subset.
In the embodiment of the present invention, the setting of the range of the touch pressure value may be performed by the user as needed, or may be performed by the user terminal according to a history setting record of the user, or may be performed by the user terminal according to an average value of the touch pressure values when the user inputs the touch operation.
In the embodiment of the present invention, when the user terminal sets the touch pressure range according to the average value of the touch pressure values when the user inputs the touch operation, the method may include the following steps:

12) determining an average value of touch pressure values in the preset time period;
13) and setting the touch pressure range to be in a range matched with the average value according to a preset setting rule.
For example, when the touch pressure values of the touch operation input by the user in one day are 0.2N, 0.3N, 0.5N, and 0.2N, and the average value of the corresponding touch pressure values is 0.3N, then (0.3+ N) N or (0.3-N) N may be set as the touch pressure range, where N is a natural number greater than 0.
The second obtaining unit 304 is configured to, if the second detecting unit 303 detects that the touch pressure value falls within a preset touch pressure value range, obtain a luminance value corresponding to the touch pressure value range from a mapping relationship between the preset touch pressure value range and the luminance value, where luminance values corresponding to different touch pressure value ranges are different.

In the embodiment of the present invention, a mapping relationship between the touch direction and the rotation direction may also be preset in the user terminal. The mapping relationship between the touch direction and the rotation direction is mainly used for describing the corresponding relationship between the touch direction and the rotation direction, that is, the rotation directions corresponding to different touch directions are different. For example, when the touch direction is the first direction, the corresponding rotation direction may also be the first direction; when the touch direction is the second direction, the corresponding rotation direction is the second direction.

That is, the angles corresponding to different pressure value ranges are different. For example, when 0.1N to 0.3N is the first pressure value range, 0.3N to 0.8N is the second pressure value range, and 0.8N to 1N is the third pressure value range, wherein the angle corresponding to the 0.1N to 0.3N is 5 degrees, the angle corresponding to the 0.3N to 0.8N is 10 degrees, and the angle corresponding to the 0.8N to 1N is 15 degrees.

The first direction and the second direction are opposite directions.
In the embodiment of the present invention, the preset mapping relationship between the touch direction and the rotation direction may be set by the user as needed, or may be set by the user terminal according to a history setting record of the user; the invention is not limited.

For example, when the third obtaining unit 314 obtains the rotation angle corresponding to the touch pressure value range as 10 degrees from the mapping relationship between the preset pressure value range and the angle, and the determining unit 315 determines the target rotation direction corresponding to the target touch direction as the first direction from the mapping relationship between the preset touch direction and the rotation direction, the first control unit 316 may control the flash to rotate 10 degrees along the first direction.
