Embodiment
Other scopes that system for the present invention and method are suitable for are by obvious in following provided detailed description.It must be appreciated following detailed description and specific embodiment, when proposing the example embodiment about portable electron device and shooting light compensation method, only as the object described and and be not used to limit the scope of the invention.
The schematic diagram of the portable electron device of Fig. 1 display according to one embodiment of the invention.As shown in Figure 1, portable electron device 100 comprises image capture unit 110, processing unit 120 and backlight module 130.Wherein, portable electron device 100 can be intelligent mobile phone, flat computer etc.Photographing module 110 is in order to capture multiple image.Wherein, portable electron device 100 also can comprise the modules such as call module, memory cell and touch control unit, because the technical characteristic of above-mentioned module is similar to prior art, therefore is not described to simplify explanation at this.Photographing module can comprise the elements such as camera lens, aperture and sensor (such as CCD, CMOS etc.).In addition, photographing module 110 also in order to the parameter of testing environment, the brightness of such as environment or colour temperature etc., and export sense signal accordingly.But the testing result of varying environment parameter will affect the different exposal model of photographing module 110 activation.When user takes in dim environment, due to the deficiency of light, photosensitivity (ISO value) can be heightened or switch to Night by usual electronic installation automatically, but image acquired with this understanding there will be the phenomenon of graininess or textured noise, causes image quality lower; Also or, electronic installation by activation one light compensating lamp, to obtain brightness preferably image.But when user utilizes front camera lens to take pictures, because most electronic installation is all without light compensating lamp before configuration, therefore user then must carry out the action of light filling in other manners.
According to one embodiment of the invention, when the environmental parameter detected by photographing module 110 be unfavorable for user obtain preferably image time, namely export one sensing signal to processing unit 120.Then, when user trigger take pictures mechanism time, signal of transmission one being taken pictures is to processing unit 120, and processing unit 120 exports one according to above-mentioned take pictures signal and above-mentioned sensing signal and drives signal to carry out the action of light filling with activation backlight module 130.Wherein, the formation of backlight module 130 comprises the elements such as light, reflector plate, light guide plate, prismatic lens and diffusion sheet.
Backlight module 130, after reception drives signal, will highlight display unit 140 and carry out light filling with activation throw light.It should be noted that user can according to personal like's sets itself colour temperature, to project the light of different colours; Also or the environment colour temperature of processing unit 120 detected by photographing module 110 automatically select corresponding light.In addition, user also can the intensity of sets itself light and activation throw light one given time, to obtain preferably image quality.It should be noted that photographing module 110 and backlight module 130 are towards a set direction, for example, in time carrying out auto heterodyne action, is in the lump towards the direction of user.After display unit 140 is used to backlight module 130 throw light given time, the image acquired by display.
The flow chart of the shooting light compensation method of Fig. 2 display according to one embodiment of the invention.First, user by activation camera function, and exports one and to take pictures signal (step S201).Step S202, the parameter of photographing module 110 testing environment also exports corresponding sensing signal to processing unit 120.For example, the brightness of photographing module 110 testing environment and colour temperature etc., the light determining environment to provide processing unit 120 whether sufficient (step S203).Wherein, the testing result of varying environment parameter will affect the different exposal model of photographing module 110 activation.For example, when user takes in dim environment, due to the deficiency of light, photosensitivity can be heightened, switch to Night or activation one light compensating lamp, to obtain brightness preferably image by usual electronic installation automatically.
If when the environmental parameter detected by photographing module 110 can maintain certain image quality, then enter step S205, carry out the action of image capture.But, when the environmental parameter detected by photographing module 110 be unfavorable for user obtain preferably image time, namely export one sensing signal to processing unit 120.Processing unit 120 drives signal to carry out the action (step S204) of light filling with activation backlight module throw light by exporting one according to take pictures signal and sensing signal.Wherein, user can according to personal like's sets itself colour temperature, to project the light of different colours; Also or the environment colour temperature of processing unit 120 detected by photographing module 110 automatically select corresponding light.In addition, user also can the intensity of sets itself light and activation throw light one given time, to obtain preferably image quality.It should be noted that photographing module 110 is with backlight module 130 towards a set direction, for example, in time carrying out auto heterodyne action, photographing module 110 and backlight module 130 are in the lump towards the direction of user.
Enter step S205, processing unit activation photographing module 110 is to capture multiple image.Finally, backlight module 130 is in activation throw light given time and after completing the action of image capture, display unit 140 shows the image (step S206) captured.
In sum, the portable electron device proposed according to one embodiment of the invention and shooting light compensation method, if when user is for utilizing front camera lens to take pictures, but when light compensating lamp, backlight module by driving liquid crystal displays makes its throw light, replaces light compensating lamp to carry out the action of light filling.Thus, user in the environment of insufficient light, according to method proposed by the invention, can carry out adjustment and the control of light filling line, and obtains quality preferably image.
The above embodiments describe with enough details and make the description of those skilled in the art's energy above implement disclosed system and method; and it must be appreciated; under the prerequisite not departing from spirit of the present invention and scope; can do some changes and retouching, therefore protection scope of the present invention is as the criterion with claim of the present invention.
