When, brightness drive signal is sent to central processing unit；
Camera have natural light shoot brightness range, be the first brightness preset value to the second brightness preset value, taken the photograph when detecting
As ambient brightness that head is taken pictures is in when the brightness range that detect that the ambient brightness natural light that camera is taken pictures is shot, that is, it is more than
First predetermined luminance value when being less than the second predetermined luminance value, does not need light adjusting, i.e. automatic trigger mobile terminal is taken pictures；Work as inspection
When measuring the ambient brightness of camera bubble-cap and being less than the first predetermined luminance value, judgement camera is in half-light environment, when detecting
When the ambient brightness that camera is taken pictures is higher than the second predetermined luminance value, then judges that camera is in light environment, taken the photograph when detecting
When the ambient brightness taken pictures as head is in half-light environment or light environment, camera needs light filling that could shoot, and sends brightness
Drive signal is to central processing unit.
B1, the central processing unit receive the brightness drive signal, and brightness driving instruction, driving camera is called to carry out
Luminous intensity is adjusted；
Central processing unit receives brightness drive signal, calls brightness driving instruction, controls light filling, and driving camera carries out luminous intensity
It adjusts.
C1, when detecting that the camera luminous intensity of mobile terminal is adjusted to third predetermined luminance value, the central processing
Device calls photographing instruction, control output automatic camera drive signal to control the mobile terminal automatic camera, and the third is default
Brightness value is between first predetermined luminance value and second predetermined luminance value.
Third predetermined luminance value is that camera natural light shoots brightness value of taking pictures best in brightness range, when needing light filling
When operation, it is preferred that adjust the luminous intensity of camera to optimal brightness value, i.e. third predetermined luminance value, detect and take the photograph
As head luminous intensity be third brightness preset value when, central processing unit call photographing instruction, control output automatic camera driving letter
Number, the automatic camera instruction control mobile terminal automatic camera.
