Abstract
The invention relates to a method and system for improving a shooting effect of a flash lamp. Firstly, a camera is started and a shooting mode is started; secondly, whether the shooting mode is one with a flash lamp turned on; if so, a color temperature value of the flash lamp is selected, wherein the color temperature value is obtained by carrying out measurement on the color temperature value of the flash lamp in advance; and thirdly, a white balance parameter matched with the color temperature value, measured in advance, of the flash lamp is further determined and white balance adjusting is carried out according to the white balance parameter. Therefore, during the debugging process of the system, color temperature parameters and white balance parameters of all flash lamps can be read, thereby selecting to start corresponding shooting debugging parameters to enable the different flash lamps to obtain the same shooting effect. And because the white balance parameter matched with the color temperature parameters, measured in advance, of the flash lamps are obtained, images with color cast phenomena during the shooting processed by different shoot lamps can be adjusted, thereby improving the shooting effects of the flash lamps.
Description
Technical field
The present invention relates to technical field of image processing, particularly relate to a kind of take pictures method and system of effect of photoflash lamp that promotes.
Background technology
Present various portable terminal substantially all has been equipped with camera, has also all equipped photoflash lamp simultaneously.
Photoflash lamp important parameter such as brightness and colour temperature in the process of producing can not be accomplished good consistency in process of production, such as, the range of color temperature of the photoflash lamp of employing LED is generally at 5000K---and 7000K, brightness value is at 180lm-300lm.This needing in the process of software debugging just to cause lamp to gamut to carry out effect being corrected to same level, guarantee consistent with the effect of a product, but present technical can't the realization.This just causes, because the individual difference of photoflash lamp, and the photoflash lamp that can't obtain same effect with a product effect of taking pictures, even the meeting that has colour cast is very serious.
Summary of the invention
Based on this, be necessary for because the individual difference of photoflash lamp, so that there are differences with a photoflash lamp effect of taking pictures, even the relatively poor problem of effect that causes taking pictures, provide a kind of take pictures method and system of effect of photoflash lamp that promotes.
A kind of take pictures method of effect of photoflash lamp that promotes comprises step:
Open camera, enter exposal model;
Judge whether described exposal model is the exposal model of opening photoflash lamp;
If, then select the photoflash lamp color temperature value that measurement is obtained to the photoflash lamp color temperature value in advance, the white balance parameter that the definite and described photoflash lamp color temperature value of measuring in advance is complementary carries out white balance adjusting according to described white balance parameter.
A kind of take pictures system of effect of photoflash lamp that promotes, comprise start take the unit, judge processing unit, the ram memory cell of photoflash lamp color temperature value that white balance adjusting unit and storage are obtained by photoflash lamp color temperature value acquiring unit;
Described startup is taken the unit and is used for opening camera, enters exposal model;
Describedly judge that processing unit is used for judging whether described exposal model is the exposal model of opening photoflash lamp;
It is when opening the exposal model of photoflash lamp that described white balance adjusting unit is used at described exposal model, then select the photoflash lamp color temperature value that measurement is obtained to the photoflash lamp color temperature value in advance, the white balance parameter that the definite and described photoflash lamp color temperature value of measuring in advance is complementary carries out white balance adjusting according to described white balance parameter.
The take pictures method and system of effect of above-mentioned lifting photoflash lamp, by opening camera, enter exposal model, judge whether described exposal model is the exposal model of opening photoflash lamp, if not, then normally take pictures, if then select the photoflash lamp color temperature value that measurement is obtained to the photoflash lamp color temperature value in advance.The white balance parameter that the further definite and described photoflash lamp color temperature value of measuring in advance is complementary carries out white balance adjusting according to described white balance parameter.So that system in debug process, can read color temperature parameters and the white balance parameter of each photoflash lamp, allow different photoflash lamps obtain the identical effect of taking pictures thereby can select to start the corresponding tuning parameter of taking pictures.By obtaining the white balance parameter that is complementary with the described photoflash lamp color temperature value of measuring in advance, the image of different photoflash lamps easy colour cast in the process of taking pictures is regulated the effect thereby the raising photoflash lamp is taken pictures.
