Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
As shown in Figure 1, be the running environment figure of camera system of the present invention.In the present embodiment, camera system 10 runs in electronic installation 1, for utilizing camera 20 to take pictures.Described electronic installation 1 can be the equipment such as mobile phone, palmtop PC (Personal Digital Assistant, PDA).In the present embodiment, described electronic installation 1 also comprises photoflash lamp 30, light sensor 40, memory 50 and processor 60.Described light sensor 40 is for the brightness value of 1 environment of living in of electronic installation described in sensing.
Described photoflash lamp 30 can be LED(Light Emitting Diode) lamp.In the present embodiment, described camera system 10 regulates the power output of described photoflash lamp 30 in the time taking pictures according to the brightness of described electronic installation 1 environment of living in, to carry out exposure compensating when the photograph taking.In the present embodiment, described camera system 10 can obtain from described camera 20 or described light sensor 40 brightness value of described electronic installation 1 environment of living in.
Described memory 50 for storing various data, for example, is stored the sequencing code of described camera system 10.Described camera system 10 can be divided into one or more modules, and described one or more modules are stored in described memory 50 and by processor 60 and carry out, to complete function provided by the invention.For example, consult shown in Fig. 2, described camera system 10 is divided into memory module 11, acquisition module 12, recognition module 13, adjustment module 14 and control module 15.The alleged module of the present invention has been the program segment of a specific function, will in the flow chart of Fig. 3, specifically describe about the function of each module.
As shown in Figure 3, be the flow chart of the preferred embodiment of photographic method of the present invention.
Step S1, memory module 11 is stored the lighting parameter table of comparisons of photoflash lamp 30, this lighting parameter table of comparisons is for recording the power output of photoflash lamp 30 in the time of different photographical condition, and described photographical condition comprises whether described electronic installation 1 ambient brightness of living in and the photo that will take exist face.
Particularly, the described lighting parameter table of comparisons can comprise at least three fields, is used for respectively the brightness of recorded electronic device 1 environment of living in, the photo that will take whether to have face and photoflash lamp 30 corresponding power output under aforementioned two conditions.
For example, user according to actual needs, arranges the light that captured photo comprises face and environment of living in and is more for example less than 50lux(Lux in the described lighting parameter table of comparisons) time, the power output of described photoflash lamp 30 is total power.And for example, light that captured photo comprises face and environment of living in is brighter for example in the time of 50～150lux, and the power output that described photoflash lamp 30 is set is flat-out 1/2.
It should be noted that, the setting of above-mentioned the exemplified lighting parameter to described photoflash lamp 30 is only for clearly demonstrating the present invention.In practice, can specifically be arranged according to the experience of taking pictures by user or be programmed by program development personnel time, preset.
Step S2, acquisition module 12 obtains the real-time pictures that camera 20 is taken under focal modes.
Step S3, whether the real-time pictures that recognition module 13 identifications are taken in there is face.
Particularly, described recognition module 13 can adopt any face recognition technology of the prior art to carry out the picture that identification takes in and whether have face.For example, can adopt face reference template method, design in advance and store the template of one or more standard faces in memory 50, then taken in picture is mated with stored standard faces template, judge whether to exist face according to matching degree threshold value.And for example, according to complexion model method, utilize the looks colour of skin relatively concentrated rule that distributes in color space to detect taken in picture and whether comprise face.
Step S4, acquisition module 12 obtains the brightness value of described electronic installation 1 environment of living in.
Particularly, described acquisition module 12 can obtain from the light sensor of this electronic installation 1 40 brightness value of this electronic installation 1 environment of living in.It should be noted that, because described camera 20 also has the function of electronic installation 1 ambient brightness of living in described in sensing, in other embodiments, described acquisition module 12 also can obtain from described camera 20 brightness value of this electronic installation 1 environment of living in.
Step S5, adjustment module 14, according to whether having face in obtained ambient brightness value and the real-time pictures taken in, arranges the power output of described photoflash lamp 30 in the time taking pictures.
Particularly, described adjustment module 14 can arrange the power output of described photoflash lamp 30 in the time taking pictures according to the lighting parameter table of comparisons storing in advance.Suppose to recognize taken in picture and have face, the brightness of environment of living in is 100lux, and in described lighting parameter table, preset light luminance that captured photo comprises face and environment of living in the time of 50～150lux, the power output of described photoflash lamp 30 is flat-out 1/2.Adjustment module 14 can the power output of described photoflash lamp 30 in the time taking pictures be set to flat-out 1/2 so.
Step S5, control module 15 is controlled camera 20 and is taken pictures, and controls described photoflash lamp 30 simultaneously and is carried out exposure compensating according to the regulate power output arranging.
Finally it should be noted that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not depart from the spirit and scope of technical solution of the present invention.
