Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Embodiment one
Referring to Fig.1, a kind of step flow chart of image capturing method of the embodiment of the present invention one is shown.
Image capturing method provided in an embodiment of the present invention the following steps are included:
Step 101: obtaining the preview image for being directed to target face.
When being taken pictures, front camera or rear camera is called to obtain the preview graph for being directed to target face
Picture.
Step 102: according to preview image, determining white of the eye region, nasal area and skin area.
Resampling processing is carried out to preview image, generates target image.Resampling refers in the information according to a kind of picture dot
Insert the process of another kind of picture dot information.In remote sensing, resampling is that low resolution is extracted from high-resolution remote sensing image
The process of image.
In the present embodiment, it can be split processing to preview image, preview image is divided into several are specific, have
The image of peculiar property obtains white of the eye region, nasal area and skin area from each image of segmentation
Step 103: according to the attribute of white of the eye region, nasal area and skin area, determining exposure adjusted value.
It, can be with according to white of the eye region, nasal area and skin area since the skin area of the people of the different colours of skin is different
Detect the colour of skin, the corresponding automatic exposure value of the facial image of the different colours of skin is different, passes through white of the eye region, nasal area and skin
Skin region determines exposure adjusted value.
Step 104: according to exposure adjusted value, shooting operation being executed to target face.
Target face is shot by exposing adjusted value, since exposure adjusted value is directed to the different colours of skin, exposure adjustment
Value is different, then the image effect of the target face after shooting is more preferably.
In embodiments of the present invention, the preview image of target face is directed to by obtaining；According to preview image, the white of the eye is determined
Region, nasal area and skin area；According to the attribute of white of the eye region, nasal area and skin area, determine that exposure is adjusted
Whole value；According to exposure adjusted value, to target face execute shooting operation, can be realized by white of the eye region, nasal area and
