In practical applications, a user may want to turn on a flash of a terminal so as to supplement light during a shooting process with the flash, or illuminate in a dark environment. In the related art, a user generally needs to control the flash lamp through a user interface, that is, the user needs to open the user interface and execute related operations in the user interface to control the flash lamp to be turned on, so that the user operation is cumbersome, and the control efficiency of the flash lamp is low.

All the above optional technical solutions can be combined arbitrarily to form optional embodiments of the present disclosure, and the embodiments of the present disclosure are not described in detail again.
Fig. 2 is a flowchart illustrating another flash control method according to an exemplary embodiment, which is applied to a terminal, as shown in fig. 2, and includes the steps of:
in step 201, the occluded state of the camera is detected.
In the process that a user uses the terminal, the terminal can automatically detect the shielding state of the configured camera, so that the flash lamp is controlled to be turned on or off according to the shielding state of the camera, and the control efficiency is improved.
The camera may be a front camera or a rear camera, which is not limited in the embodiments of the present disclosure.
The sheltered state of the camera may include a duration of sheltering the camera, a number of times that the camera is sheltered continuously, or an interval duration of sheltering the camera twice continuously, and the like, and may also include sheltered states in other forms, which is not limited in the embodiment of the present disclosure.
In practical application, detecting the shielded state of the camera may include the following two implementation manners:
in a first implementation, the shielded state of the camera is detected by a photosensitive element of the camera.
The camera can detect incident light through the configured photosensitive element, and whether the camera is sheltered or not is judged through the detected light. For example, it may be determined that the camera is occluded when the currently detected light intensity decreases by a preset threshold relative to the last detected light intensity or there is suddenly no incident light, or by other light conditions.
The second implementation mode is that the light sensor detects the sheltered state of the camera, and the light sensor is located in the preset distance range of the camera.
The light sensor is called as a brightness sensor and comprises a light projector and a light receiver, and the light sensor can detect the light brightness of the environment where the terminal is located. The embodiment of the disclosure summarizes, the sheltered state of the light sensor can be determined according to the light brightness detected by the light sensor, and then the sheltered state of the camera located in the preset distance range of the light sensor is determined according to the sheltered state of the light sensor.
The preset distance range can be set by a terminal in a default mode, and is a range which can be covered by a palm of a user, so that the shielded state of the camera is determined through the shielded state of the light sensor. Moreover, most terminals are equipped with a light sensor, and the light sensor is usually located within a preset distance range of the camera, i.e. located near the camera. For example, the light sensor is typically located on the right side of the front camera. In the disclosed embodiments.
In step 202, it is determined whether the blocked state satisfies a preset opening condition.
The preset starting condition is a condition which is required to be met by the shielding state of the preset camera, and when the terminal detects that the shielding state meets the preset starting condition, the flash lamp can be automatically started. Moreover, the preset starting condition may be set by a default of the terminal, or may be flexibly set by the user, which is not limited in the embodiment of the present disclosure. For example, the preset turn-on condition may be a preset continuous shielding duration, a preset continuous shielding number, a preset shielding interval duration, or the like of the camera.
Wherein, should judge whether should be sheltered from the state and satisfy preset opening condition can include following several kinds of modes:
the first implementation mode comprises the following steps: when the shielded state comprises the time length of shielding the camera and the shielded time length is greater than or equal to the first preset time length, determining that the shielded state meets the preset opening condition.
The first preset duration may be set by a default of the terminal, or may be set by the user according to actual needs, which is not limited in the embodiment of the present disclosure. For example, the first preset time period may be 2s, 3s, 5s, or the like.
The terminal can start timing when detecting that the camera is shielded, so that the duration of shielding the camera is determined, whether the shielded duration is greater than or equal to the first preset duration is judged, and when the shielded duration is greater than or equal to the first preset duration, the shielded state can be determined to meet the preset opening condition.
For example, if the first preset duration is 3s, when the duration of the camera being blocked is greater than or equal to 3s, it may be determined that the blocked state of the camera satisfies the preset opening condition.
The second implementation mode comprises the following steps: and when the shielded state comprises the continuous shielded times of the camera and the continuous shielded times are more than or equal to the preset times, determining that the shielded state meets the preset opening condition.
The preset times may be set by default by the terminal, or may be set by the user according to actual needs, which is not limited in the embodiments of the present disclosure. For example, the preset number of times may be 2 times, 3 times, 5 times, or the like.
The terminal can accumulate the continuous shielded times of the camera when detecting that the camera is shielded every time, judge whether the accumulated continuous shielded times is greater than or equal to the preset times, and determine that the shielded state meets the preset opening condition when the accumulated continuous shielded times is greater than or equal to the preset times.
For example, if the first preset duration is 3 times, when it is detected that the camera is continuously shielded for 3 times, it may be determined that the shielded state of the camera satisfies the preset turn-on condition.
The third implementation mode comprises the following steps: and when the shielded state comprises the interval duration of the camera being shielded for two times continuously and the interval duration is less than or equal to the second preset duration, determining that the shielded state meets the preset opening condition.
The second preset duration may be set by a default of the terminal, or may be set by the user according to actual needs, which is not limited in the embodiment of the present disclosure. For example, the second preset time period may be 1s, 2s, 3s, or the like.
The terminal can calculate the interval duration between the shielding and the last shielding when detecting that the camera is shielded every time, and judge whether the interval duration is less than or equal to the second preset duration, and when the interval duration is less than or equal to the second preset duration, it can be determined that the shielded state meets the preset opening condition.
For example, if the first preset duration is 1s, when it is detected that the duration of the interval between two consecutive times of shielding of the camera is less than or equal to 1s, it may be determined that the shielded state of the camera satisfies the preset turn-on condition.
And a fourth implementation manner, in combination with any two or 3 of the three implementation manners, of judging whether the shielded state of the camera meets the preset starting condition.
That is, the terminal may determine whether the shielded state of the camera satisfies the preset turn-on condition by combining any two or 3 conditions of the shielded duration, the shielded times and the interval duration.
For example, the terminal may determine that the shielded state of the camera satisfies the preset opening condition when the terminal satisfies any two or 3 of a duration that the camera is shielded is greater than or equal to the first preset duration, a number of times that the camera is continuously shielded is greater than or equal to the preset number of times, and an interval duration that the camera is continuously shielded twice is less than or equal to the second preset duration.
Taking the example of judging whether the shielded state of the camera meets the preset opening condition by combining the shielded times and the interval duration, the terminal can determine that the shielded state of the camera meets the preset opening condition when the continuous shielded times of the camera are greater than or equal to the preset times and the interval duration of any two continuous shielded times in the continuous shielded times is less than or equal to the second preset duration.
For example, if the preset number of times is 3 times and the second preset duration is 1s, the terminal may determine that the blocked state of the camera satisfies the preset opening condition when detecting that the camera is blocked for 3 consecutive times and the time interval between any two consecutive blocked times is less than 1 s.
In step 203, when the shielded state satisfies the preset turn-on condition, a flash is turned on.
When the terminal determines that the shielded state meets the preset starting condition, the flash lamp can be automatically started, so that a user does not need to open a user interface and execute related operations in the user interface, and does not need to execute any key operation, the flash lamp can be quickly started and stopped only by shielding the camera, the operation mode is simple and quick, the user operation is simplified, and the control efficiency is improved. Moreover, the mode of quickly starting the flash lamp by shielding the camera is carried out in a cool manner, and the user experience is improved.
For example, the user can use the camera to shoot the in-process, when feel that the current shooting environment is more to need to mend light, shelter from the camera 3 times fast with the palm and open the flash light to the quick opening of flash off lamp has been realized.
In addition, after the flash is turned on, the flash needs to be turned off when the user no longer needs the flash, and in order to avoid the user needing to turn off the flash through the complicated operation of the user interface, the embodiment of the present disclosure further improves a manner of rapidly turning off the flash, which is shown in step 204 and 205 described below.
In step 204, when it is detected that the camera is occluded, a duration of time that the camera is occluded is determined.
That is, in the process of using the flash after the flash is turned on, the terminal may further continue to detect whether the camera is shielded, and when it is detected that the camera is shielded, the duration of the shielding of the camera may be determined. For example, the terminal may start a timer to start timing when it is detected that the camera is shielded, and stop timing when it is detected that the camera is no longer shielded, so as to determine the duration of shielding the camera by timing.
In step 205, the flash is turned off when the determined duration is greater than or equal to a third preset duration.
The third preset time period may be set by the terminal, or may be set by the user according to actual needs, which is not limited in the embodiment of the present disclosure. For example, the third preset time period may be 4s, 5s, 10s, or the like.
That is, after the flash lamp is started, when the shielded duration of the camera is determined to be greater than or equal to the third preset duration, the flash lamp can be automatically turned off so as to avoid the electric quantity consumption of the flash lamp, and the control mode is simple and quick, so that the control efficiency and the user experience are improved.
For example, in practical application, after the flash lamp is turned on, when the terminal is placed in a pocket for a long time or the camera is placed on a desktop downwards, the camera is always in a shielding state, and the flash lamp can be automatically turned off at the moment, so that power consumption trouble cannot be caused to a user.
It should be noted that, in the embodiment of the present disclosure, the flash lamp is only turned off automatically when the duration of the camera being shielded is longer than a certain duration, and in practical applications, the flash lamp may also be turned off in other shielded states of the camera.
For example, the flash may be turned off when the number of times of continuous shielding of the camera is greater than or equal to a preset number of times, and the preset number of times is different from the preset number of times for turning on the flash. For example, the flash lamp may be turned on when the number of consecutive blocked times of the camera is greater than or equal to a first preset number, and turned off when the number of consecutive blocked times of the camera is greater than or equal to a second preset number, where the first preset number is different from the second preset number, for example, the first preset number is smaller than the second preset number.
In the embodiment of the disclosure, the sheltered state of the camera can be detected, and the flash lamp is automatically turned on when the sheltered state of the camera meets the preset turning-on condition, so that the user can conveniently control the flash lamp to turn on by sheltering the camera, thereby simplifying the operation of the user and improving the control efficiency of the flash lamp.
