Since the luminous power of display screen itself is limited, if the brightness of display screen is unable to reach light filling requirement, electricity is controlled
The supplementary lighting sources on sub- equipment front top are opened, so that supplementary lighting sources carry out front light filling together with display screen.Therefore, this implementation
In mode, first adjust display screen to maximum brightness, while acquiring current environment luminous intensity, if current environment luminous intensity still less than
The lower limiting value of preset range of light intensities, then it represents that the light filling of display screen is unable to reach light filling requirement, at this time control electronics
The supplementary lighting sources on positive top are opened.If current environment luminous intensity is greater than or equal to the lower limiting value of preset range of light intensities,
It indicates that the brightness of display screen can reach light filling requirement, therefore light filling is only carried out by the brightness of display screen.
Certainly, ground is changed, in order to enable control process is succinct, can also judge that it is default that current environment luminous intensity is less than
Range of light intensities lower limiting value when, while adjust display screen to maximum brightness and control supplementary lighting sources open so that display screen
With front light filling is carried out together with supplementary lighting sources.So simply, conveniently.
