Detailed description of the invention
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.It is understood that this
Specific embodiment described by place is used only for explaining the present invention, rather than limitation of the invention.The most also need
It is noted that for the ease of describing, accompanying drawing illustrate only part related to the present invention and not all knot
Structure.
Embodiment one
The schematic flow sheet of the image pickup method of the anti-light interference that Fig. 1 provides for the embodiment of the present invention one, the method
Can be performed by the filming apparatus of anti-light interference, wherein this device can be realized by software and/or hardware, can make
A part for intelligent terminal is built in inside intelligent terminal.Include as it is shown in figure 1, this realizes flow process:
Step 11, the photographic head started in intelligent terminal.
In the present embodiment, intelligent terminal can be such as smart mobile phone, panel computer and personal computer it
The electronic product of class, and intelligent terminal is configured with photographic head.
Step 12, determine in the ambient light of described intelligent terminal whether there is interference light.
In this embodiment, ambient light refers to the light that photographic head can collect, and interference light refers to cause clapping
Take the photograph in result and reduce the light of shooting quality, such as light sources such as TV, computer or street lamps containing broad image
Light.Concrete, environment photoemissive optical signal information can be passed through, determine in ambient light whether there is interference
Light.
If step 13 exists interference light, then shorten the time of exposure of described photographic head, and shoot.
The general 1/30s of acquiescence time of exposure of mobile phone camera at present, if the frequency of interference light is 50Hz-60Hz,
Then owing to acquiescence time of exposure is much larger than the flicker frequency of interference light, cause interference with photoimaging and obscure.This enforcement
In example by interference optical transmission of information that light sensor is collected to ISP (Image Signal Processing,
Image-signal processor), ISP adjusts the time of exposure of photographic head according to the result obtained.It is shortened by shooting
The time of exposure of head makes the time of exposure after adjusting close with the flicker frequency of interference light, makes interference light adjust
In time of exposure after whole can blur-free imaging, improve shooting quality.
The technical scheme that the present embodiment provides, in photographic head shooting process, is determined by the ring of intelligent terminal
Whether border light existing interference light, if there is interference light, then shortening the time of exposure of photographic head, it is to avoid interference
The shooting quality that optical flare causes is relatively low, i.e. solve the shooting knot disturbing optical flare to cause in prior art
The problem containing broad image in Guo, improves the satisfaction of Consumer's Experience.Further, interference light is being detected
Shi Zidong shortens the time of exposure of photographic head and simplifies user operation compared to user's manual adjustment time of exposure,
Improve shooting efficiency.
Exemplary, determine and whether the ambient light of described intelligent terminal exists interference light, including:
Detect the brightness value of the ambient light of described intelligent terminal；
If the difference between the brightness value of any environment light and the brightness value of other ambient lights, bright more than preset
Degree difference limen value, it is determined that whether there is interference light in the ambient light of described intelligent terminal.
Wherein it is possible to when monitoring light interference incident, determine whether the ambient light of intelligent terminal exists dry
Disturb light.Concrete, detect the brightness value of all ambient lights by the luminance sensor of configuration in intelligent terminal,
If the difference between the brightness value of any environment light and the brightness value of other ambient lights more than luminance difference threshold value (as
300lux), it is determined that this ambient light is bright ambient light, and produce light interference incident；Otherwise, continuing monitoring is
No there is light interference incident.By determining the ring of intelligent terminal after monitoring light interference incident again in the present embodiment
Whether border light exists interference light, it is possible to effectively reduce the identification number of times of interference light, it is to avoid interference light identification is led
The intelligent terminal's wasting of resources caused.
Embodiment two
The present embodiment is on the basis of above-described embodiment one, it is provided that the image pickup method of a kind of new anti-light interference.

The wavelength of light.Owing to the wavelength X of light, frequency f and light velocity c have a following relation: C=λ f.Thus,
After the wavelength of ambient light being detected, i.e. can determine that the frequency of ambient light.
Exemplary, according to the frequency of the ambient light that light sensor in described intelligent terminal detects, determine
Whether described ambient light exists interference light, if may include that light sensor detection in described intelligent terminal
The frequency of the ambient light arrived is in default interfering frequency scope, it is determined that described ambient light is interference light.Wherein,
Interfering frequency scope is 50Hz-60Hz.
Exemplary, according to the wavelength of the ambient light that light sensor in described intelligent terminal detects, determine
Whether described ambient light exists interference light, if may include that light sensor detection in described intelligent terminal
The frequency of the ambient light arrived is in default interference wave-length coverage, it is determined that described ambient light is interference light.Wherein,
Interference wave-length coverage is 560nm-700nm.
If step 23 exists interference light, then frequency and/wavelength according to described interference light shorten described photographic head
Time of exposure.
Exemplary, controlling the time of exposure of photographic head with the frequency of interference light is negative correlation, i.e. interference light
The time of exposure of frequency the biggest control photographic head the shortest, so that time of exposure meets the interference photoimaging of flicker
Required time, thus improve shooting quality.Such as, the frequency of interference light is 60Hz, controls time of exposure and is
1/120s；The frequency of interference light is 50Hz, and control time of exposure is 1/100s.
Exemplary, the wavelength of the time of exposure and interference light that control photographic head is proportionate, i.e. interference light
The time of exposure of wavelength the biggest control photographic head the longest.
The technical scheme that the present embodiment provides, by determining in ambient light according to the frequency of ambient light and/or wavelength
Whether light is disturbed in existence, and if there is interference light, according to frequency and/or the wavelength shortening photographic head of interference light
Time of exposure so that time of exposure meets the interference photoimaging required time of flicker, thus improve shooting matter
Amount.
