Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is part of the embodiment of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, the every other implementation that those of ordinary skill in the art are obtained without creative efforts
Example, belongs to the scope of protection of the invention.
A kind of image pickup method, device and shifting provided by the invention is discussed in detail below by several specific embodiments are enumerated
Dynamic terminal.
Embodiment one
With reference to Fig. 1, show a kind of step flow chart of image pickup method of the embodiment of the present invention one, can specifically include such as
Lower step：
Step 101, when receiving shooting sign on, the background area in the realtime graphic frame to acquisition and people are passed through
Face region is analyzed, and determines optimal dimming model.
The embodiment of the present invention is suitable for having shooting picture, video, the mobile terminal of dynamic picture.Wherein, mobile terminal
Including but not limited to mobile phone, tablet computer.
The embodiment of the present invention can be analyzed from each picture frame captured in real time, and be dimmed, so as to ensure every frame
Image reaches best shooting effect and stereovision.It is appreciated that the embodiment of the present invention is equally applicable to shoot individual figure
Picture.
Specifically, for a two field picture, first, the human face region in image and background area are identified；Then, difference is passed through
The characteristics of background area and human face region, is analyzed, from default dimming model, obtains optimal dimming model.
Wherein, to the identification of human face region and background area, human face region can first be identified by face recognition technology,
Or human face region is selected by shooting user, so that other regions are as background area.
The characteristics of background area and human face region, includes but not limited to：The color of background area, the skin shape of human face region
Age that state, the colour of skin and analysis obtain, gender etc..The embodiment of the present invention can pass through different colors, the colour of skin and year
Age, gender get optimal dimming model.
Default dimming model includes but not limited to：Rembrandt's light model, butterfly light model, shadow-free light model, multiple light courcess
Model, width light model, demifacet light model, backlight model.It is as shown in Figure 1A the effect by Rembrandt's light from side polishing,
It is the effect that polishing is carried out by butterfly lighting as shown in Figure 1B, Fig. 1 C and 1D are by the image after polishing.Therefrom can be with
Find out, the picture stereovision respectively shot afterwards by polishing is stronger, shooting effect is more preferable.
Step 102, using brightness of the optimal dimming model to the human face region in the realtime graphic frame and colour temperature
It is adjusted.
The embodiment of the present invention so as to strengthen the stereovision of human face region and shoot by the independent polishing of human face region, imitating
Fruit.
Specifically, by the brightness of each pixel of human face region and colour temperature, it is adjusted according to designated model.
Wherein, the brightness of each pixel shows the light levels of image, and the embodiment of the present invention can be different by adjusting
The brightness of position pixel so that preferable visual effect is presented in image.For example, as shown in Figure 1A, from right side polishing, by left side of the face
The brightness in portion is turned down, so as to improve visual effect.In another example as shown in Figure 1B, by the brightness around underthe nose, eyes, neck
The brightness of son is turned down, and the brightness in face front, forehead and chin is heightened, so as to improve visual effect.
Colour temperature is a measurement unit for representing to include color component in light.Theoretically, colour temperature refers to definitely black
The color that body is presented after being heated since absolute zero (- 273 DEG C).Black matrix by blacking is gradually red after heated, then
Switch to yellow, rear is white, eventually becomes blueness.When being heated to certain temperature, the spectral component contained by light that black matrix is sent is just
Colour temperature referred to as at a temperature of this, measurement unit are " K " (Kelvin).If under the light that a certain light source is sent, with a certain temperature
The spectral component contained by light that black matrix is sent is identical, that is, is known as certain K colour temperature, and definitely black as 100W light bulbs send the color of light
Color of the body in 2527K is identical, then the colour temperature for the light that this light bulb is sent is 527K+273K=2800K.The present invention is implemented
Example can be by adjusting colour temperature so that preferable visual effect is presented in image.For example, warm light meeting is used in some scenarios
So that image shows a kind of warm, comfortable effect, and can be rendered using cold light in some scenarios a kind of dreary, miserable
Effect.
Step 103, when receiving shooting END instruction, the image collection that human face region is adjusted is preserved, is clapped
Take the photograph image set.
In embodiments of the present invention, image collection of the human face region Jing Guo polishing will be passed through as shooting figure image set, so that
The video of shooting, dynamic image etc. show relatively good shooting effect, improve the shooting enthusiasm of user.
In embodiments of the present invention, when receiving shooting sign on, the back of the body in the realtime graphic frame to acquisition is passed through
Scene area and human face region are analyzed, and determine optimal dimming model；Using the optimal dimming model to the realtime graphic
The brightness of human face region in frame and colour temperature are adjusted；When receiving shooting END instruction, human face region is preserved through toning
Whole image collection, obtains shooting figure image set.Solve the problems, such as that picture stereovision is weaker, shooting effect is poor, reached increasing
The beneficial effect of strong picture stereovision and shooting effect.
