and adjusting the driving current of the flash lamp according to the change of the adjusting switch and the corresponding relation between the adjusting switch and the driving current of the flash lamp, so as to adjust the illumination brightness of the flash lamp.
The brightness adjusting method provided by the invention can be applied to various intelligent terminals, such as cameras, intelligent mobile phones, tablet computers, intelligent televisions, laptop portable computers, desktop computers, intelligent watches and other intelligent terminals with flash lamps, and the specific type of the intelligent terminal is not limited.
The brightness adjusting method provided by the invention can be applied to various situations that the flash-off lamp is used as a photographing auxiliary tool or used as a lighting tool and the like.
Taking a smart phone as an example, the brightness adjusting method provided by the invention realizes the adjustment of the brightness of the flash lamp by setting an adjusting switch for controlling the brightness of the flash lamp in the flash lamp. The adjusting switch for controlling the brightness of the flash lamp is connected with the driving current or driving voltage or pulse width modulation duty ratio modulation signal of the flash lamp, a corresponding relation is set, the driving current or driving voltage or pulse width modulation duty ratio modulation signal of the flash lamp is controlled by controlling the adjusting switch, and then the brightness of the flash lamp is adjusted. When the flash lamp is used as a lighting tool, the flash lamp can be used as a desk lamp by adjusting the flash lamp to the comfortable brightness of human eyes through the steps.
It can be understood that the adjusting switch for controlling the brightness of the flash lamp can be designed as an entity switch, a touch switch or only certain specific gestures on the smart phone, the adjusting switch can be in various forms such as an entity switch, an entity button, an entity key, an entity rotation key and the like which are already or newly arranged on the smart phone, or in various forms such as a touch switch, a touch key and the like in a camera or a flashlight application program on the smart phone, or in gestures such as long-press up-down sliding, long-press left-right sliding and the like on a screen of the smart phone, and the specific form of the adjusting switch is not limited.
In a preferred embodiment, the setting of the adjustment switch of the flash, and the setting of the correspondence relationship between the adjustment switch and the flash drive current includes:
setting a volume key of the intelligent terminal as an adjusting switch of the flash lamp, increasing the driving current of the flash lamp when setting a volume key "+", and decreasing the driving current of the flash lamp when setting a volume key "-".
The brightness adjusting method provided by the invention can be designed to adjust the brightness of the flash-off lamp by adjusting the volume key as long as the flashlight application in the intelligent mobile phone is in an open state; or when the flashlight application in the intelligent mobile phone is in an open state and the screen is in a screen-off state, the brightness of the flash-off lamp can be adjusted by adjusting the volume key; or when the flashlight application in the intelligent mobile phone is in an open state and the current page is the page of the flashlight application program, the brightness of the flashlight can be adjusted by adjusting the volume key.
As described above, the adjustment switch may be set as a volume key on the smartphone, and a corresponding relationship may be set between the volume key and the driving current or driving voltage of the flash or the pulse width modulation duty modulation signal, for example, the driving current of the flash may be increased when the volume key "+" is set, and the driving current of the flash may be decreased when the volume key "-" is set. Thus, when the user presses the volume key "+" of the smart phone, the driving current of the flash lamp is increased, and the brightness of the flash lamp is increased. The user can continuously press the volume key of the smart phone to realize continuous adjustment of the brightness of the flash lamp. Similarly, the volume keys of the smart phone are in different forms according to different models of different manufacturers of the smart phone, and can be various forms such as an entity switch, an entity button, an entity key, an entity rotation key and the like which are already or newly arranged on the smart phone, a touch switch, a touch key and the like in a camera or a flashlight application program on the smart phone, or gestures such as up-down sliding and left-right sliding of long-press on a screen of the smart phone, and the specific forms of the volume keys are not limited.

For example, the level of volume adjustment of the volume key may be designed to be higher than brightness adjustment of the flash light, so that when a user listens to and watches audio and video and makes a call by using a line control earphone or externally placing the line control earphone on the smart phone, the volume key is adjusted, the volume of listening to and watching the audio and video and making a call is adjusted, but not the brightness of the flash light, and if the user needs to further adjust the brightness of the flash light, the user needs to enter an application program of a camera or a flashlight and use other modes for adjustment; the volume key can be adjusted, the volume of listening and watching the audio and video and making a call is adjusted at first, after the volume is adjusted for a period of time, such as 1min, the volume key is continuously adjusted, the brightness of the flash lamp can be adjusted, and certainly, the brightness of the flash lamp can be adjusted to be higher than the level of the volume adjustment; or, the method can be designed to adjust the volume key, firstly adjust the volume for listening and watching the audio and video and making a call, if the user needs to further adjust the brightness of the flash lamp and needs to enter the application program page of the camera or the flashlight, then adjust the volume key and adjust the brightness of the flash lamp; or, it may be designed to adjust the volume key, and first detect whether the current page of the smartphone is an application program requiring volume adjustment, such as a communication application, a music application, a video application, or an application program requiring brightness adjustment, such as a camera application, a flashlight application, or the like, and if the current page is an application program requiring volume adjustment, for example, the current page is a phone page, adjust the volume key to adjust the volume, and if the current page is an application program requiring brightness adjustment, for example, a flashlight, adjust the volume key to adjust the brightness, and if neither of the current page is the phone page, first adjust the volume, and if the user needs to further adjust the brightness of the flashlight, the user needs to enter the application program page of the camera or the flashlight, and then adjust the volume key to adjust the brightness of the flashlight.
In an embodiment, the volume key may adopt different forms to adjust the volume and the brightness, so as to distinguish the volume and the brightness, for example, one click of the volume key may be designed to adjust the volume of the smartphone, and a double click of the volume key may be designed to adjust the brightness of the flashlight of the smartphone. In an embodiment, taking an entity volume key on the side of a smart phone as an example, when a user presses the volume key, a pop-up box prompts the user on a screen that the brightness of a flash lamp needs to be adjusted or the volume needs to be adjusted, and according to different selections of the user, the brightness or the volume is adjusted after the user continues to press the volume key; or, taking a touch switch on the smart phone as an example, when the user presses a volume key, the volume and brightness adjusting keys can be displayed on the screen of the smart phone at the same time, if the up and down keys are brightness adjustment, and the left and right keys are volume adjustment; or, taking the touch screen gesture control on the smart phone as an example, when the user presses the volume key, the screen of the smart phone is lit, and after the screen is unlocked, the user slides up and down at the right-hand end of the screen in the horizontal screen or vertical screen state of the smart phone to adjust the brightness, and slides up and down at the left-hand end of the screen to adjust the volume.
