Detailed description of the invention
The invention provides the control method of brightness when a kind of photographic head starts, for making the purpose of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein is used only for explaining the present invention, be not intended to limit the present invention.
The invention provides the control method of brightness when a kind of photographic head starts, as it is shown in figure 1, said method comprising the steps of:
S1, photographic head start before, obtain the brightness value of current camera shooting terminal local environment, and described brightness value be sent to central processing unit.
Before photographic head starts, by being arranged on the optical sensor above camera shooting terminal or the brightness value residing for other light intensity acquisition device acquisition current environment, and described brightness value is sent to central processing unit.Current environment is the ambient condition of camera shooting terminal present position, and it can be indoor, outdoor and dark place.
Before being arranged on photographic head startup due to this step, in order to realize smoothly completing, in the specific implementation, can arrange after central processing unit receives the instruction that user sends startup photographic head, it is then turned on after first controlling photographic head delay predetermined time, but trigger optical sensor and obtain the brightness value of current environment, obtain the brightness value of current environment.When, after the brightness value getting current environment, according to the brightness of current environment, photographic head being initialized.The described scheduled time is not less than central processing unit and is triggered to the brightness value of optical sensor acquisition current environment, until described brightness value is fed back to photographic head by central processing unit, photographic head arranges the time of exposure initial value automatically.
Described brightness value and predetermined luminance threshold value are compared by S2, described central processing unit, it is judged that current camera shooting terminal local environment state is indoor, outdoor or dark place, and selects corresponding exposure initial value according to result of determination.
After central processing unit receives the brightness value of current environment, itself and predetermined luminance threshold value are compared, it is judged that current environment is indoor or outdoor or dark place, and selects to expose initial value accordingly according to judged result.
Also include before described step S1:
S11, respectively two predetermined luminance threshold values being configured in advance, two predetermined luminance threshold values are: predetermined luminance upper limit threshold and predetermined luminance lower threshold；Described predetermined luminance upper limit threshold is more than predetermined luminance lower threshold.When the brightness value obtained is beyond brightness upper limit threshold, then by stronger for current environment brightness ratio, it is determined that for outdoor, if being between brightness upper limit threshold and lower threshold, then judge that current environment is as indoor, if the brightness value of current environment is lower than brightness lower threshold, then judge that current environment is as dark place.
In order to better according to the result determined, the exposure initial value that corresponding selection is suitable, also include before described step S1:
S12, pre-building the ambient condition one-to-one relationship with exposure initial value, described corresponding relation is: the corresponding first exposure initial value of outdoor environment；The corresponding second exposure initial value of dark place environment；The corresponding 3rd exposure initial value of indoor environment.
Described step S2 also includes:
S21, when whether judging described brightness value more than predetermined luminance upper limit threshold, if more than, then judge that currently displaying terminal local environment state is as outdoor, otherwise perform step S22.
S22, judge that whether described brightness value is less than predetermined luminance lower threshold, if less than, then judge that currently displaying terminal local environment state is as dark place, otherwise, it is determined that the gone out ambient condition of currently displaying terminal is indoor.
Described step S2 also includes:
S23, when judging that currently displaying terminal local environment state is for outdoor, then choose corresponding with outdoor environment the first exposure initial value as exposure initial value；It is dark place when judging currently displaying terminal local environment state, then chooses the second exposure initial value corresponding with dark place environment facies as exposure initial value；When judging that currently displaying terminal local environment state is for indoor, then choose the threeth exposure initial value corresponding with dark place environment facies as exposure initial value.
The exposure initial value that S3, basis are selected carries out photographic head initialization.
Owing to selecting exposure initial value according to current ambient conditions in above-mentioned steps, then photographic head can directly be initialized by this step according to the exposure initial value selected, it is achieved brilliance control when shooting is started.
