Here, in the case where the terminal meets preset condition, by electric to target electromagnetic Tie Tong, alternatively, stopping pair
The target electromagnetic Tie Tong electricity, alternatively, the size for the electric current that adjustment is applied on the target electromagnetic iron and/or direction, in turn
Achieve the purpose that adjust the distance between lampshade and light source, to meet the difference in the gap under different scenes to light source and lampshade
Demand.
In order to avoid due to the distance between lampshade and light source it is too small, terminal be in fall state when, light source is by lampshade
Collide, protect light source, prevent light source to be damaged, as one optionally implementation, the terminal meet preset condition, can have
Body includes:
The acceleration of gravity of the terminal is greater than the first preset threshold, and the distance between lampshade and light source are pre- less than first
If distance value.
It is, the terminal, which is in, falls state, and the distance between lampshade and light source are less than the first pre-determined distance value.
When terminal meets above-mentioned preset condition, size and/or the direction of the electric current being applied on target electromagnetic iron are adjusted,
The distance between lampshade and light source is set to increase to first object value.
Here, target electromagnetic iron is mainly determined by the actual hardware structure of terminal.
Here, terminal can determine whether the acceleration of gravity of terminal is greater than the first preset threshold by acceleration transducer,
That is, determining whether terminal is in by acceleration transducer falls state.
In addition, can by the way that range sensor is arranged around lampshade or light source, with know between lampshade and light source away from
From.
In Terminal Design, since height of materials tolerance and build-up tolerance cause the gap of light source and lampshade unstable, meeting
It influences terminal to take pictures the consistency of calibration by light source, in order to guarantee that terminal is taken pictures the consistency of calibration by light source, as another
One optionally implementation, the terminal meet preset condition, may particularly include:
Ratio in the corresponding shot region of light source between the brightness value of four angular zones and the brightness value of central area is greater than
Second preset threshold；Alternatively,

In addition, the ratio in the corresponding shot region of light source between the brightness value of four angular zones and the brightness value of central area
Less than third predetermined threshold value, illustrate that calibration discovery light source (herein referring to flash lamp) is taken pictures spot center overexposure, quadrangle is excessively dark, also
It is to say, the distance between light source and lampshade are bigger than normal, and in order to guarantee that terminal is taken pictures the consistency of calibration by light source, terminal is meeting
When the preset condition, size and/or the direction of the electric current being applied on target electromagnetic iron are adjusted, it will be between lampshade and the light source
Distance be decreased to third target value.
Specifically, adjustment is applied on two third electromagnet 6 as shown in Figure 1, terminal is when meeting the preset condition
The distance between lampshade and the light source are decreased to third target value by the size of electric current and/or direction.
In addition, user is when clapping distant view using flash lamp, it is desirable to which the distance that light can shine is farther, can illuminate to light
Area size is of less demanding, wishes that flash lamp and the gap of flash lamp lampshade are the bigger the better this when；And user is utilizing sudden strain of a muscle
When light lamp claps close shot, it is desirable to which the region that light can illuminate is the bigger the better, and wishes this when between flash lamp and flash lamp lampshade
Gap is the smaller the better, in order to meet it is different take pictures scene the needs of, as one, optionally implementation, the terminal meet default item
Part may particularly include:
When being taken pictures by the light source of the terminal, the distance between photograph subject and the terminal in view-finder are greater than the
Two pre-determined distance values, and the distance between lampshade and light source are less than third pre-determined distance value；Alternatively,

Four pre-determined distance values, and the distance between lampshade and light source are greater than the 5th pre-determined distance value.
It should be noted that when being taken pictures by the light source of the terminal, photograph subject and the terminal in view-finder it
Between distance be greater than the second pre-determined distance value, illustrate that user takes pictures carrying out distant view using flash lamp, and at this point, lampshade and light source
The distance between be less than third pre-determined distance value, that is, the distance that light shines is not remote enough, in order to meet the need of taking pictures of user
It asks, terminal adjusts size and/or the direction of the electric current being applied on target electromagnetic iron, by lamp when meeting above-mentioned preset condition
The distance between cover and the light source increase to the 4th target value；
In addition, when being taken pictures by the light source of the terminal, the distance between photograph subject and the terminal in view-finder
Less than the 4th pre-determined distance value, illustrate that user takes pictures carrying out close shot using flash lamp, and at this point, between lampshade and light source away from
Not big enough from greater than the 5th pre-determined distance value, that is, the region that light illuminates, in order to meet the demand of taking pictures of user, terminal exists
When meeting above-mentioned preset condition, size and/or the direction of the electric current being applied on target electromagnetic iron are adjusted, by lampshade and the light
The distance between source is decreased to the 5th target value.
