Problems solved by technology
When the mobile phone takes pictures or videos in low light, it needs to turn on the flash to fill in the light. Because objects absorb and reflect light differently, even if the flash is turned on when taking pictures, the results are not very ideal.
Especially for objects with less light absorption and more reflection, when the flash is turned on to take pictures at night, most areas of the photo will appear very white, and the glare cannot be seen clearly
[0003] At present, since the brightness of the photographing environment cannot be adjusted when the flash is turned on, the user will not be able to see the object being photographed clearly when taking a photo

The invention discloses a flash lamp control device for a mobile terminal. The flash lamp control device comprises a power supply management module, a differential control module and an on-off control module, wherein the differential control module is used for controlling a flash lamp to be turned on slowly and turned off slowly; the on-off control module is used for controlling the on and off states of the flash lamp; the power supply end of the power supply management module is connected with the input end of the differential control module; the output end of the differential control module is connected with the anode of the flash lamp through the on-off control module; and the cathode of the flash lamp is connected with the flash signal drive end of the power supply management module. According to the flash lamp control device for the mobile terminal provided by the invention, the flash lamp is controlled to be turned on slowly and turned off slowly by the differential control module, so that the brightness of the flash lamp can be adjusted to the environmental brightness which is suitable for shooting; and therefore, not only strong reflected light of an object can be reduced, but also the shooting effect can be improved effectively.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a flashlight control device for a mobile terminal. Background technique [0002] With the development of mobile phone technology and the improvement of market competitiveness, taking pictures has become an essential function of mobile phones. When the mobile phone takes pictures or videos in low light, it needs to turn on the flash for supplementary light. Because objects absorb and reflect light differently, even if the flash is turned on when taking pictures, the effect of shooting is not very ideal. Especially for objects with less light absorption and more reflection, when the flash is turned on at night to take pictures, most areas of the photo will appear very white, and it will be dazzling and unclear. [0003] At present, since the brightness of the photographing environment cannot be adjusted when the flash is turned on, the user cannot clearly see the object being ...
