Step 202, the photometry region and focal length of camera are determined according to above-mentioned location information.
In the embodiment of the present application, after the target reference object for including in identifying current preview frame image, you can really
Recognize the location information of target reference object.
The selection of photometry region is accurate one of the important evidence for choosing shutter and F-number.The survey spectrum of camera
System carries out the selection of photometry region, also referred to as reflective survey generally by the reflected brightness of subject is measured
Light.
Specifically, camera generally assumes that the reflecting rate of photometry region is 18% automatically, survey light is carried out by this ratio,
It is later determined that the numerical value of aperture and shutter.
Under same illumination condition, if to obtain identical light exposure, f-number is bigger, then fast gate value is needed to get over
It is small, and if f-number is smaller, need fast gate value bigger.18% this numerical value source is according to middle tone in natural scene
Depending on the reflective performance of (gray tone), if white tone is in the majority in picture of finding a view, reflection light will be more than 18%, if it is
Complete white scene, can reflect about 90% incident light, and if it is black scenes, possible reflectivity only has a few percent.
Standard gray card is one 8 × 10 inches of card, this gray card is placed on the same survey light source of shot subject, acquired
Photometry region entirety reflecting rate be exactly the 18% of standard, then only need the diaphragm shutter value provided by camera to be clapped
It takes the photograph, it will be that exposure is accurate to shoot the photo come.
If the overall reflectivity of entire photometry region is more than 18%, for example, the background of photometry region is based on white tone,
At this moment if being shot if the diaphragm shutter value measured according to camera automatic light measuring, the photo shot will be one
The photo exposed is owed, white background may appear to the burnt hair that seems, that is shot if it is a blank sheet of paper will become one
Open black paper.So shooting reflecting rate is more than 18% scene, the exposure bias value EV for increasing camera is needed., whereas if clapping
The scene that reflecting rate is less than 18%, such as the background of black are taken the photograph, often overexposure, the background of black can also become the photo taken
Grey.So shooting reflecting rate is less than 18% scene, it is desirable to reduce EV exposes.
Current Exposure Metering mainly has central average metering, central Partial metering, spot light-metering, Multi spot metering and evaluation
Survey light.Wherein, central average metering is using a kind of most metering modes, and the embodiment of the present application is with the side of central average metering
The selection of photometry region is illustrated in formula.
Wherein, shooting main body mainly is namely needed accurately to expose by central average metering in view of general cameraman custom
The target object of light is placed on the centre of view finder, so this part content of shooting is most important.Therefore it is responsible for surveying the sense organ of light
Element can organically separate the whole light value of camera, and the photometric data of center portion occupies most ratios, and draws
Photometric data other than the center of face plays the booster action for surveying light as fraction ratio.By camera processor to this two
Ratio after lattice numeric weights are average, obtains the photometric data of camera shooting.For example, setting camera center portion surveys light
Occupy it is entire survey the 75% of light ratio, other non-central portion gradually extend to edge photometric data occupy 25% ratio
Example.
It can thus be seen that it needs to be determined that after the position of good target object, you can carry out the selection of photometry region, example
Such as, using the location of target object as the center portion of photometry region.
In addition, the selection of camera focal length is usually to emit one group of infrared ray or other rays by camera, through subject
The distance of subject is determined after reflection, and camera lens combination is then adjusted according to measured distance, realizes auto-focusing.Therefore, it is also desirable to
After the position for determining target object, the focal length for frame image of taking pictures is obtained.

Enable the location information of corresponding target reference object.
For example, as shown in figure 3, user by take pictures triggered in preview interface to above-mentioned preview frame image 31 in include
Target reference object 32 choose instruction, obtain and above-mentioned to choose the location information for instructing corresponding target reference object, that is, by
User directly chooses the target reference object for needing to focus, without in such a way that current preview frame image is identified
It obtains so that the selection of target reference object is more accurate.
Optionally, the frame image as shown in figure 4, above-mentioned acquisition focusing is successfully taken pictures, including：Step 401 is to step 402.
Step 401, the pixel value of the characteristic point of current preview frame image and upper preview frame image corresponding position are calculated
The difference of the pixel value of characteristic point.
Wherein, the characteristic point of current preview frame image refers to the pixel of predeterminated position in current preview frame image, for example,
Positioned at the pixel of current preview frame image center location, alternatively, the target reference object wheel in current preview frame image
The pixel at wide edge.
Step 402, it if above-mentioned difference is less than the second predetermined threshold value, is successfully clapped using current preview frame image as focusing
According to frame image.
In the picture of the pixel value and the characteristic point of upper preview frame image corresponding position of the characteristic point of current preview frame image
When the difference of element value is less than above-mentioned second predetermined threshold value, indicates to have completed the focusing to photograph subject, can directly acquire and work as
Preceding preview frame image is as frame image of taking pictures.
Optionally, in above described embodiment, according to camera enabled instruction detection terminal whether in default fortune
Before dynamic state, including：Whether the exposal model for detecting camera is default exposal model, if detecting the exposal model of camera not
Belong to default exposal model, then after receiving photographing instruction, the acquisition for the frame image that take pictures.
In the embodiment of the present application, above-mentioned default exposal model refers to the pattern for being used to indicate terminal and carrying out snapshots.
Specifically, whether the exposal model of detection camera is that default exposal model includes：Read the phase stored in register
