Refer to Fig. 1, Fig. 1 is the schematic flow sheet of a kind of image pickup method that the embodiment of the present invention provides, and in embodiments of the present invention, the method can comprise the following steps.
S101: when the preposition shooting instruction for terminal being detected, obtains the current colour temperature of described terminal place environment.
In order to meet the actual demand of user for image taking, current most of terminal is all equipped with multiple camera, to enrich camera function, such as: the configurable front-facing camera of terminal provides preposition camera function for user, autodynes to facilitate user; Or, the configurable packaged type camera of terminal, to facilitate user to carry out multi-angle image shooting, etc.For mobile phone, the terminal in the embodiment of the present invention can be the mobile phone possessing front-facing camera, and also can be the mobile phone possessing packaged type camera, concrete, the embodiment of the present invention be restricted, as long as can realize the equipment of preposition camera function.Wherein, preposition shooting is the situation that subject corresponding to pointer terminal screen front carries out taking, and rearmounted shooting refers to carries out the situation of taking for the subject that the terminal screen back side is corresponding, usually, user adopts preposition shooting to realize autodyning, as taken face, bodyside etc.
For convenience of understanding, to possess the forward and backward mobile phone putting camera, at present, after starting the shooting application on mobile phone, normally acquiescence starts post-positioned pick-up head, because in routine work life, user uses post-positioned pick-up head frequently.Therefore, in existing mobile phone, the configuration of post-positioned pick-up head is also far away higher than front-facing camera, as post-positioned pick-up head is usually equipped with photoflash lamp; But for saving production cost, front-facing camera not only configures lower, and is not equipped with photoflash lamp; Therefore, when user adopts front-facing camera autodyne or take for user's body side, the captured picture quality obtained is poor, especially when ambient light is darker.In the embodiment of the present invention, user can put shooting switching button by forward and backward in click camera application, also can be start front-facing camera by the physical button triggering terminal clicked in terminal or packaged type camera moved to automatically the target location performing preposition shooting, and start camera, concrete, the embodiment of the present invention is not restricted.
In specific implementation, can pre-set physical button, wherein, default physical button can be any one or more physical button in terminal, and such as, volume increases key, volume reduces key or power key etc., and concrete, the embodiment of the present invention is not restricted.User can produce different click action by clicking physical button, as single is clicked, double-clicks, clicked for continuous three times; When terminal detects and physical button occurs click action, identify the particular type of click action, if the click action that physical button occurs is default target click action, then illustrate that user wishes that terminal starts preposition shooting, therefore, start front-facing camera or packaged type camera moved to automatically the target location performing preposition shooting, and starting camera.
In the embodiment of the present invention, when the preposition shooting instruction for terminal being detected, obtain the current colour temperature of terminal place environment.Wherein, colour temperature (color temperature) is the yardstick representing that light source is photochromic, and unit is K (Kelvin).Usually, the difference of ambient light intensity, corresponding colour temperature is just not identical.Colour temperature is higher, photochromic blue; Colour temperature is lower, photochromic red.Such as, in the middle of one day, the photochromic of light also changes in time; After sunrise 40 minutes photochromic more yellow, colour temperature 3000K; Afternoon, sunlight was snow-white, rose to 4800-5800K; Cloudy day the meridian hour then about 6500K; Photochromic partially red before sunset, colour temperature is down to 2200K again.Again such as, the colour temperature of candle light is approximately 2000K; Early morning environment colour temperature greatly about 4400K; High noon in summer, the colour temperature of environment was approximately 5500K.
S102: adopt default white balance adjusting rule to regulate described current colour temperature, obtain target colour temperature.
Usually, when colour temperature is higher, color is partially blue; When colour temperature is on the low side, color is partially red or partially yellow.So-called white balance, refers to the reduction of video camera to white object.Because user possesses adaptability to the colour reproduction of object under different light rays, therefore, under naked eyes viewing different light rays during the object of same color, sensation is identical substantially.Such as, respectively in the morning, under night dim light, daytime is when seeing same white object under noon sun, all can feel that this object is white.But, as video camera, under different light, due to the disequilibrium that CCD (Charge-coupled Device, charge coupled cell also can be called ccd image sensor) exports, cause video camera colour reproduction distortion.Such as, show as partially yellow when taking white object morning, show as indigo plant etc. partially daytime takes white object under noon sun time, cause the image color distortion of shooting.
In shooting process, the color temperature value according to the current colour temperature corresponding to external environment is taken, and color is partially warm, and namely partially yellow, the color temperature value according to the current colour temperature corresponding to external environment is taken, and color is colder, namely partially blue.In the embodiment of the present invention, the light filling image being exported different colours by terminal screen carries out light filling and white balance adjusting, improves picture quality.Concrete, after getting the current colour temperature of environment residing for terminal, adopt default white balance adjusting rule to regulate described current colour temperature, obtain target colour temperature.Wherein, target colour temperature is used to indicate the color of the light filling image needing to export on a terminal screen, thus the light filling image exported by terminal screen is regulated the current colour temperature of environment residing for terminal.
In specific implementation, presetting white balance adjusting rule can be: the current color temperature value of aim colour temperature value environment residing for terminal.Such as, the current color temperature value supposing to get environment residing for terminal is 3000K, then can determine that aim colour temperature value is 3000K, therefore, needs the pre-set image of light filling image corresponding to 3000K exported on a terminal screen.
Consider that the colour of skin of user itself is yellow, therefore, when adopting camera to take, if target colour temperature during shooting is lower than the current colour temperature corresponding to external environment, photochromic partially warm, owing to obtaining white after blue and yellow superposition, therefore, can make user's colour of skin whitening, usually, most of user wishes that the colour of skin after taking is comparatively whiter than the colour of skin own.Therefore, in specific implementation, presetting white balance adjusting rule can also be: aim colour temperature value current color temperature value of environment residing for terminal deducts the difference after preset color temperature value.Wherein, preset color temperature value can set in conjunction with actual needs, but as one preferred embodiment, can pre-set this color temperature value is 700 ~ 800K.For convenience of understanding, suppose that preset color temperature value is 700K, if the current color temperature value then getting environment residing for terminal is 3000K, then can determine that aim colour temperature value is 3000K-700K=2300K, therefore, the pre-set image of light filling image corresponding to 2300K exported on a terminal screen is needed.
S103: light filling image corresponding for described target colour temperature is exported in the screen of described terminal; Wherein, described light filling image is used for carrying out light filling to the reference object of preposition shooting.
As a kind of example, when adopting preposition camera function to take face-image under can investigating different-colour environment in advance, by exporting the picture quality of the face-image that different light filling image obtains in terminal screen, determine the corresponding relation of colour temperature and light filling image.Such as, colour temperature can be divided into multiple grade, the light filling image be in corresponding to the colour temperature in same grade is identical, therefore, after obtaining target colour temperature, first judge the grade residing for target colour temperature, the light filling image then corresponding to this grade determination target colour temperature.In specific implementation, after terminal obtains need the target colour temperature of light filling according to current colour temperature, according to the corresponding relation of colour temperature and light filling image, determine the light filling image corresponding to target colour temperature, and light filling image is exported in terminal screen.
As another kind of example, also can be the corresponding relation according to colour temperature and color, determine the color corresponding to target colour temperature, export the monochrome image that this Color pair is answered on a terminal screen.Thus the light filling image shown on a terminal screen can carry out light filling to the reference object of preposition shooting, such as, during shooting face-image, the light of light filling image exposes to user's face, and the image that shooting is obtained seems that the colour of skin is whiter.
Usually, the mode of identification color has multiple, as modes such as RGB, HSL.Wherein, rgb color pattern is a kind of color standard of industrial quarters, by obtaining color miscellaneous to the change of red (R), green (G), blue (B) three Color Channels and their superpositions each other, namely RGB is the color representing red, green, blue three passages, this standard almost include human eyesight can all colours of perception, be use one of the widest color system at present.Therefore, as one preferred embodiment, the corresponding relation of colour temperature and RGB can be set up in advance, thus, after obtaining a target colour temperature, can uniquely determine a kind of rgb value according to this corresponding relation, obtain the monochrome image that this RGB is corresponding.In specific implementation, after the current colour temperature of environment obtains target colour temperature residing for terminal, according to the corresponding relation of colour temperature and RGB, determine the RGB that described target colour temperature is corresponding; The monochrome image of described RGB is exported in the screen of described terminal.
HSL color mode is by obtaining color miscellaneous to the change of form and aspect (H), saturation (S), lightness (L) three Color Channels and their superpositions each other, HSL represents form and aspect, saturation, the color of lightness three passages.
For convenience of understanding, the embodiment of the present invention enumerates the corresponding relation of part colour temperature and RGB, and this corresponding relation can be as shown in table 1, what deserves to be explained is, table 1 is only wherein a kind of signal.
Table 1
| Colour temperature (K) | RGB |
| 2600 | (113，100，29) |

| 3200 | (106，100，45) |
| 3300 | (105，100，47) |
| 4000 | (101，100，64) |
| 5000 | (98，100，86) |
| 6500 | (97，100，104) |
Therefore, based on table 1, if obtaining target colour temperature is 2700K, then known, be (112,100,32) by RGB numerical value corresponding for the monochrome image exported on a terminal screen.
S104: perform preposition camera operation, obtains the target image of described reference object when described light filling image carries out light filling.
In specific implementation, after exporting light filling image on a terminal screen, light filling image carries out light filling to reference object, therefore, performs preposition camera operation when light filling image carries out light filling, obtains the target image of described reference object when described light filling image carries out light filling.Known, the light filling image when preposition camera operation by screen shows has carried out light filling process to the image of reference object, therefore, can improve photographic images quality.In specific implementation, after performing preposition camera operation, the output of light filling image can be closed, and the target image obtained captured by display on a terminal screen, thus, facilitate user to browse shooting results, i.e. preview target image.
