The present invention combines ISP technologies, proposes a kind of exposure method of new photographing device, overcomes in the prior art,
When shooting the big scene of light and shade gap, such as shooting the portrait that the deep colour of skin and the shallow colour of skin coexist, AE technologies are difficult to meet exposure need
The problem asked.
The content of the invention
Novel intelligent terminal photographic method proposed by the present invention, its can zoning picture automatically brightness value, work as judgement
When luminance difference value is more than a certain threshold values, then starts ISP and AE is compensated into segmentation, so as to realize the different exposure journeys of same picture
Degree, it is big to solve photographed scene light and shade gap in the prior art, and causes what bright or excessively dark image cannot normally show
Problem.
Specifically, the present invention proposes a kind of photographic method of intelligent terminal, comprises the following steps：S1:Start mobile terminal
Program of taking pictures；S2:Obtain the brightness value in selected shooting area, and each luminance area coordinate；S3:Obtain the shooting area
The difference of maximum brightness value and minimum luminance value in domain；S4:Judge the difference whether more than threshold value；S5:If the difference is big
In the threshold value, then automatic ISP, according to the coordinate of each luminance area, splits the AE compensation configurations of intelligent terminal；If described
Difference is less than or equal to the threshold value, then be continuing with giving tacit consent to exposal model；S6:Completion is taken pictures.
Preferably, database is set in the intelligent terminal, for the brightness value obtained in storing step S2 and institute
State coordinate value.
Preferably, it is characterised in that the shooting area is face identification region.
Preferably, the threshold value is the brightness value for being set in intelligent terminal in advance.
Preferably, the intelligent terminal has data processing module, for calculating the luminance difference in different shooting areas,
And it is compared with the threshold value.
Preferably, the program of taking pictures is the self-contained program of taking pictures of the intelligent terminal.
Preferably, the program of taking pictures is the application program of the operating system exploitation based on the intelligent terminal.
Preferably, the intelligent terminal is digital camera, panel computer or smart mobile phone.
Compared with prior art, it is of the invention it is a technical advantage that：
1) present invention is capable of achieving adjust automatically AE exposure configurations, even if bright in light and shade gap according to luminance difference in scene
In aobvious scene, the normal display of image can be also realized.
2) present invention can adjust automatically intelligent terminal exposure configuration, meet it is amateur photography user to shoot image quality want
Ask.
Brief description of the drawings
Fig. 1 is the flow chart of the photographic method of an intelligent terminal for meeting one embodiment of the present invention.
Specific embodiment
Superiority of the invention is elaborated below in conjunction with drawings and the specific embodiments.
Refering to Fig. 1, it is the flow chart of the photographic method of an intelligent terminal for meeting one embodiment of the present invention.From figure
In as can be seen that present embodiments provide a kind of photographic method of intelligent terminal, it specifically includes following steps：
S1:Start the program of taking pictures of mobile terminal；When user needs to shoot photo, can be from the quick figure of intelligent terminal desktop
Button of taking pictures is selected in mark, or quick drop-down menu, and starts program of taking pictures.
Preferably, the program of taking pictures can be the self-contained program of taking pictures of the intelligent terminal, or or be based on
The application program of the operating system exploitation of the intelligent terminal.
S2:Obtain the brightness value in selected shooting area, and each luminance area coordinate；Intelligent terminal enters program of taking pictures
Afterwards, system is by the brightness value/coordinate value in the automatic photographed scene obtained selected by user, and obtains above-mentioned brightness value accordingly
Corresponding coordinate value/brightness value, and acquired above-mentioned brightness value and its corresponding coordinate value are fed back into terminal.Such as, system
Face can first be detected and its correspondence position information i.e. coordinate value is obtained, and the coordinate of above-mentioned face location is fed back to intelligent terminal
Value, system obtains the brightness value Y of each human face region in scene according to the position data, and by value Y and its corresponding coordinate
Value feeds back to intelligent terminal.
Wherein it is preferred to, database is provided with intelligent terminal in the present embodiment, for being obtained in storing step S2
