Fig. 1 is referred to, Fig. 1 is a kind of schematic flow sheet of image pickup method provided in an embodiment of the present invention, of the invention real
Apply in example, this method may comprise steps of.
S101：When detecting the preposition shooting instruction for terminal, the current colour temperature of environment where obtaining the terminal.
In order to meet actual demand of the user for image taking, current most of terminal is equipped with multiple cameras,
To enrich camera function, such as：Terminal can configure front camera and provide the user preposition camera function, to facilitate user to carry out
Self-timer；Or terminal can configure packaged type camera, to facilitate user to carry out multi-angle image shooting, etc..Using mobile phone as
Example, the terminal in the embodiment of the present invention can be possessed the mobile phone of front camera or possess packaged type camera
Mobile phone, specifically, the embodiment of the present invention is not restricted, as long as can be achieved on the equipment of preposition camera function.Wherein,
Preposition shooting be pointer terminal screen front corresponding to subject situation about being shot, rearmounted shooting refers to be directed to terminal screen
The situation that subject corresponding to the back side is shot, generally, user realize self-timer using preposition shooting, such as shoot face, body
Side etc..
For convenience of understanding, by possess it is forward and backward put the mobile phone of camera exemplified by, at present, after starting the shooting application on mobile phone
Typically acquiescence starts rear camera, because in routine work life, user is frequent using rear camera.Therefore,
The configuration of rear camera is also significantly larger than front camera in existing mobile phone, as rear camera is often equipped with flash lamp；
But to save production cost, front camera not only configures relatively low, and is not equipped with flash lamp；Therefore, user uses preposition shooting
Head self-timer is for user's body side either when being shot, it is captured must picture quality it is poor, especially in ambient light
In the case of dark.In the embodiment of the present invention, user can by click on it is forward and backward in camera application put shooting switching button,
Can be by click on the physical button triggering terminal in terminal start front camera either by packaged type camera from
It is dynamic to be moved to the target location for performing preposition shooting, and start camera, specifically, the embodiment of the present invention is not restricted.
In the specific implementation, physical button can be pre-set, wherein, default physical button can be any one in terminal
Or multiple physical buttons, for example, volume increase key, volume reduce key or power key etc., specifically, the embodiment of the present invention does not limit
System.User can produce different click actions by clicking on physical button, such as single click on, double-click, continuous click three times；
When terminal detects generation click action on physical button, the particular type of click action is identified, if occur on physical button
Click action is default target click action, then illustrates that user wishes that terminal starts preposition shooting, therefore, start preposition shooting
Packaged type camera is either automatically moved into the target location for performing preposition shooting by head, and starts camera.
In the embodiment of the present invention, when detecting the preposition shooting instruction for terminal, environment where obtaining terminal is worked as
Preceding colour temperature.Wherein, colour temperature (color temperature) is the yardstick for representing that light source is photochromic, and unit is K (Kelvin).Generally,
The difference of ambient light intensity, corresponding colour temperature just differ.Colour temperature is higher, photochromic more blue；Colour temperature is lower, photochromic more inclined
It is red.For example, the photochromic of light also changes over time among one day；40 minutes photochromic more yellow, colour temperature 3000K after sunrise；Afternoon sunlight
It is snow-white, rise to 4800-5800K；Cloudy the meridian hour then about 6500K；Photochromic partially red before sunset, colour temperature is down to 2200K again.Again
For example, the colour temperature of candle light is about 2000K；The colour temperature of early morning environment is about in 4400K；The colour temperature of high noon in summer environment is about
For 5500K.
S102：The current colour temperature is adjusted using default white balance adjusting rule, obtains target colour temperature.
Generally, color is partially blue when colour temperature is higher；Color is partially red or partially yellow when colour temperature is relatively low.So-called white balance, refer to image
Reduction of the machine to white object.Because colour reproduction of the user to object under different light possesses adaptability, therefore, naked eyes are watched
Under different light during the object of same color, feel to be substantially identical.For example, respectively in the morning, under night dim light,
When seeing same white object under daytime noon sun, it is white for may feel that the object.However, as video camera,
Under different light, because CCD (Charge-coupled Device, charge coupled cell, is referred to as ccd image sensing
Device) output disequilibrium, cause video camera colour reproduction distortion.For example, show as Huang partially in the morning when shooting white object, in vain
Indigo plant etc. partially is shown as when white object is shot under its noon sun, causes the image color distortion of shooting.
In shooting process, shot according to the color temperature value higher than the current colour temperature corresponding to external environment, color
It is partially warm, i.e., it is partially yellow, shot according to the color temperature value less than the current colour temperature corresponding to external environment, color is colder, i.e., partially
It is blue.In the embodiment of the present invention, light filling and white balance adjusting are carried out by the light filling image of terminal screen output different colours, carried
High image quality.Specifically, after getting the current colour temperature of terminal local environment, using default white balance adjusting rule to described
Current colour temperature is adjusted, and obtains target colour temperature.Wherein, target colour temperature is used to indicate to need the light filling exported on a terminal screen
The color of image, so as to which the current colour temperature of terminal local environment is adjusted the light filling image exported by terminal screen.
In the specific implementation, default white balance adjusting rule can be：Target color temperature value is the current color of terminal local environment
Temperature value.For example, it is assumed that the current color temperature value for getting terminal local environment is 3000K, then it can determine that target color temperature value is
3000K, therefore, it is necessary to the light filling image exported on a terminal screen is the pre-set image corresponding to 3000K.
Consider that the colour of skin of user in itself is yellow, therefore, when being shot using camera, if target colour temperature during shooting
It is photochromic partially warm less than the current colour temperature corresponding to external environment, therefore, can be with due to obtaining white after blueness and yellow superposition
Make user colour whitening, generally, it is relatively white that most of users are intended to ratio of skin tone itself colour of skin after shooting.Therefore, it is specific real
In existing, default white balance adjusting rule can also be：Target color temperature value subtracts default for the current color temperature value of terminal local environment
Difference after color temperature value.Wherein, preset color temperature value can be combined to be actually needed and set, but be used as a kind of preferable embodiment party
Formula, it is 700~800K that can pre-set the color temperature value.For convenience of understanding, it is assumed that preset color temperature value is 700K, if then getting
The current color temperature value of terminal local environment is 3000K, then it is 3000K-700K=2300K that can determine target color temperature value, therefore,
Pre-set image of the light filling image for needing to export on a terminal screen corresponding to 2300K.
S103：Light filling image corresponding to the target colour temperature is exported into the screen of the terminal；Wherein, the light filling
Image is used to carry out light filling to the reference object of preposition shooting.
As a kind of example, can investigate in advance under different-colour environment using preposition camera function shooting face-image
When, the picture quality of the face-image obtained by exporting different light filling images in terminal screen, determine colour temperature and light filling
The corresponding relation of image.For example, colour temperature can be divided into multiple grades, the light filling figure corresponding to colour temperature in same grade
As identical, therefore, after obtaining target colour temperature, the grade residing for target colour temperature first determined whether, target is then determined according to the grade
Light filling image corresponding to colour temperature.In the specific implementation, after terminal obtains the target colour temperature for needing light filling according to current colour temperature, according to
Colour temperature and the corresponding relation of light filling image, determine the light filling image corresponding to target colour temperature, and light filling image is exported to terminal
In screen.
As another example or the corresponding relation according to colour temperature and color, determine corresponding to target colour temperature
Color, monochrome image corresponding to the color is exported on a terminal screen.So as to which, the light filling image shown on a terminal screen can be with
Light filling is carried out to the reference object of preposition shooting, for example, during shooting face-image, the light of light filling image exposes to user plane
Portion, the image for obtaining shooting seem that the colour of skin is whiter.
Generally, identifying the mode of color has a variety of, such as RGB, HSL mode.Wherein, rgb color pattern is industrial quarters
A kind of color standard, pass through the change and their mutual superpositions to red (R), green (G), blue (B) three Color Channels
To obtain miscellaneous color, RGB is the color for representing three passages of red, green, blue, and this standard almost includes the mankind
The all colours that eyesight can perceive are current with one of most wide color system.Therefore, as a kind of preferable embodiment party
Formula, colour temperature and RGB corresponding relation can be pre-established, so that, can be unique according to the corresponding relation after obtaining a target colour temperature
A kind of rgb value is determined, obtains monochrome image corresponding to the RGB.In the specific implementation, obtained according to the current colour temperature of terminal local environment
After obtaining target colour temperature, according to colour temperature and RGB corresponding relation, RGB corresponding to the target colour temperature is determined；By the list of the RGB
Color image is exported into the screen of the terminal.
HSL color modes be by form and aspect (H), saturation degree (S), three Color Channels of lightness (L) change and it
Mutual superposition obtain miscellaneous color, HSL is to represent form and aspect, saturation degree, the face of three passages of lightness
Color.
For convenience of understanding, the embodiment of the present invention enumerates part colour temperature and RGB corresponding relation, and the corresponding relation can be such as table
Shown in 1, what deserves to be explained is, table 1 is only one of which signal.
