Description
Technical field
The present invention relates to field of photographing technology more particularly to a kind of camera arrangements and method based on human eye.
Background technique
When shooting photo, in order to obtain preferable shooting effect, user can select not according to different photographed scenes
Same Exposure Metering.Light is surveyed, is the process of a measurement proper exposure, only obtains correctly exposure by surveying light, could clap
Take the photograph satisfied photo.In same shooting viewfinder range, since the reflectance of object is different, Partial exposure is necessarily had not
It is sufficient or over-exposed, in this case, it is considered that if we think that the subject content exposure of performance is correct, so that it may think
The exposure of this photo is correct.
Currently, Exposure Metering has average metering, central average metering and spot light-metering, average metering is usually that filming apparatus is silent
The basic metering mode recognized, but due to average metering be to entirely finding a view area's average computation light value, can not protrude to
The subject content that performance is wanted at family carries out survey light, causes survey light effect bad, and then can not take satisfied photo；Center is flat
Survey light be in the middle part of viewfinder range 30% or so region carry out average metering, can only to the main body in the middle part of photo expose compared with
To be correct, the subject content that performance is wanted to user can not be protruded and carry out survey light；Spot light-metering is to the 1%- in viewfinder range
Light is surveyed in 5% region, when using spot light-metering, user is needed to manually select survey luminous point, it is complicated for operation.
Above content is only used to facilitate the understanding of the technical scheme, and is not represented and is recognized that above content is existing skill

Electrical structure schematic diagram based on above-mentioned mobile terminal hardware configuration and camera proposes that the present invention is based on human eyes
The each embodiment of camera arrangement.
It is that the present invention is based on the structural schematic diagram of the first embodiment of the camera arrangement of human eye, the devices referring to Fig. 3, Fig. 3
Applied in terminal, which includes:
Trapping module 10, the image that the rear camera for capturing terminal obtains, is the first image；And for capturing end
The facial image that the front camera at end obtains；
Human eye analysis module 20 obtains eyeball information for carrying out human eye analysis to the facial image；
Optical module 30 is surveyed, for obtaining photometry result according to the eyeball information and first image；
Shooting module 40, for shooting photo according to the photometry result.
The terminal is the terminal with shooting function such as smart phone, tablet computer, camera, which includes preposition camera shooting
Head and rear camera, the front camera and rear camera can be opened simultaneously, wherein the image of rear camera acquisition
It is shown on the entire display screen of terminal (preview area or view-finder), the image of front camera acquisition is shown in the end
The image of the predeterminable area of the display screen at end, front camera acquisition is suspended on the image of rear camera acquisition.
Common, the area of the predeterminable area is less than the area of the display screen, and the shape of the predeterminable area and position can be liked according to user
The upper left corner, the upper right corner, the lower left corner or the right small angle of display screen, the preset areas is such as arranged in the predeterminable area by good self-setting
The shape in domain is rectangle.In one embodiment, the display screen of the terminal is as shown in Figure 4, wherein region A is for showing postposition
The image of camera acquisition, region B are used to show the image of front camera acquisition.When the terminal starting take pictures in application,
The display screen display two-shot button and one-shot button of the terminal, user click the two-shot button,
The front camera and rear camera are activated simultaneously；User clicks the one-shot button, the front camera or after
Camera is set to be activated.
When terminal opening is taken pictures in application, the usual hand of user holds the terminal, i.e. display screen of the user towards the terminal,
Then the trapping module 10 can obtain the facial image of user by the front camera of the terminal.
The human eye analysis module 20 analyzes the facial image, such as carries out eye recognition, obtains eye image, then
The eye image is analyzed again, obtains eyeball information.The eye image analyzed from facial image may include one
Eyes or two eyes；Common, the content that two eyes of people are seen is essentially the same, in the present invention, with the eye image
For an eyes.
The eyeball information includes the spherical surface virtual image formed by eyeball surface, can also include pupil size, etc..
The pupil of human eye has the function of that control light quantity, the myosis when environment is too bright enter eyes to reduce light；
When ambient enviroment is very dark, pupil can amplify, and to allow more light to enter eyes, reach and propose purpose high-definition.Human eye pupil
The diameter variable in hole is between 1.5-8.0mm.
Human eye can form the spherical surface virtual image in eyeball surface when being look at object, and the eyeball surface of the right and left eyes in human eye is formed
The spherical surface virtual image it is essentially the same.
The survey optical module 30 confirms whether human eye is look at the display of terminal according to the eyeball information and first image
Screen according to the spherical surface virtual image formed by the eyeball surface in the eyeball information and is somebody's turn to do if human eye is look at the display screen of terminal
First image obtains watching area of the human eye in the first image, the i.e. interested region of user, surveys to the watching area
Light obtains photometry result；If human eye is not look at the display screen of terminal, according to the pupil size in the eyeball information,
Photometry result is obtained, alternatively, carrying out average metering or center survey light or spot light-metering, pacing light at the beginning of obtaining one to first image
As a result, and according to the pupil size in the eyeball information, obtain a survey light correction value, it is first to this further according to the survey light correction value
Step photometry result is modified, and obtains photometry result.The average metering, center survey light, spot light-metering is the prior art, herein no longer
It repeats.
The photometry result is luminance information.
The shooting module 40 first determines exposure value according to the photometry result, specifically, photometry result can be preset in user
With the mapping relations of exposure value, survey after optical module 30 obtains photometry result, the shooting module 40 according to the photometry result of the acquisition,

Shooting unit 42 is used for when first clocking value is less than or equal to preset survey photolocking time threshold, according to
The photometry result shoots photo；And for continuing according to the survey light when the angular speed is less than or equal to preset angle threshold values
As a result photo is shot.
The initial clocking value of the timer is 0.
The survey photolocking time threshold can be preset, and e.g., this sets the survey photolocking time threshold to 5 seconds.At this
It surveys in photolocking time threshold, it is believed that the terminal is un-shifted, and the shooting unit 42 is according to the photometry result measured before
Shoot photo.
When first clocking value is greater than preset survey photolocking time threshold, it was initially believed that the terminal may be moved,
I.e. it was initially believed that user may cause in adjustment shooting state then if the photometry result before still using carries out shooting photo
The photographic quality of shooting is low, and therefore, which obtains the angular speed of terminal.
Optionally, which obtains the angular speed of the terminal, the angular speed by angular-rate sensor
Sensor is built in the terminal, and optionally, which is gyroscope.Wherein, gyroscope high-speed rotator
