Threshold value improves the initial luminance data of image.
Wherein, the sensitivity information of every frame image is compared with sensitivity threshold value, that is, judges the original intensity of image
Whether information, which needs, is corrected.Correspondingly, being carried out according to initial luminance data of the sensitivity information of every frame image to this frame image
It corrects, the luminance information after obtained every frame image correction, can be exactly original initial luminance information.
In the embodiment of the present invention, sensitivity information can with but be not limited only to obtain from image.
It can be pre-configured with sensitivity threshold value, repaired by comparing the size of sensitivity information and the sensitivity threshold value of image
Positive initial luminance data, for example, it is lower to represent ambient brightness, camera if the sensitivity information of image is higher than sensitivity threshold value
Brightness of image is improved by improving sensitivity, it is therefore desirable to reduce the luminance information of image, it is bright could to obtain true environment
Degree, this implementation are simple, quick.
In another implementation, every frame image is determined according to the luminance information of each pixel in every frame image respectively
Initial luminance data；Obtain the geographical location information of mobile terminal；According to the geographical location information respectively to the first of this frame image
Beginning luminance information is modified, the luminance information after obtaining every frame image correction；According to the luminance information after each frame image correction
Determine first environment luminance information.
Since geographical location information can also reflect ambient brightness, when sensitivity information can not be obtained, can pass through
Geographical location information is modified the brightness of image.
In the embodiment of the present invention, there are many implementations that obtain the geographical location information of mobile terminal, for example, from GPS
It is obtained in the satellite positioning signals such as (Global Positioning System, global positioning system) or Beidou signal geographical
Location information also can use the location technologies such as inertial navigation and obtain geographical location information.
Wherein, geographical location information can with but be not limited only to be latitude and longitude information.
In the embodiment of the present invention, the division range of mobile terminal location can there are many, such as can be it is mobile eventually
Cell etc. where province/city, mobile terminal where time zone, mobile terminal the country in which it is located, mobile terminal where end.
In the embodiment of the present invention, on the basis of geographical location information, influence ambient brightness factor can there are many, example
Such as sun position, weather condition, underground parking particular surroundings.
So, following at least one information: mobile terminal location can be specifically determined according to the geographical location information
Whether current sun position information, mobile terminal location current weather information, mobile terminal are in abnormal environment brightness region
Domain or in scheduled distance or guidance path in the time with the presence or absence of scheduled abnormal luminance area；According to determining information
The initial luminance data of this frame image is modified respectively.
In the embodiment of the present invention, geographical location information can be obtained at predetermined intervals, according to newest acquisition
Geographical location information determines above- mentioned information.
In practical application, it can configure and only determine current sun position information, can also configure and only determine current weather letter
Breath can also configure and both determine sun position information or determining weather information.
Wherein it is possible to the sun position of different regions and the corresponding relationship of time be pre-saved, according to above-mentioned geographical location
Information finds the sun position of the geographical location information location and the corresponding relationship of time, searches and works as in the corresponding relationship
Preceding time corresponding sun position information；Geographical location information can also be sent to network server, and receive network service
The sun position information that device returns.
Geographical location information can be sent to network server, by network server by geographical location information location
Current weather information return to mobile terminal.
The corresponding relationship of sun position information and/or weather information and ambient brightness can be pre-saved, by searching for right
Answer the above-mentioned current sun position information of Relation acquisition and/or the corresponding ambient brightness information of current weather information.The present invention is implemented
In example, sun position information and/or the corresponding ambient brightness information of weather information are known as first environment luminance information.
Wherein, abnormal luminance area refer to ambient brightness different from the region of the normal outdoor environment brightness in this area, such as
Lower parking lot, tunnel etc..
In the embodiment of the present invention, it can determine that mobile terminal is currently according to the real-time geographical location information of mobile terminal
It is no to be in abnormal environment luminance area.Specifically, geographical location information is inputted electronic map, determined whether according to electronic map
In abnormal environment luminance area.
If mobile terminal movement speed is very fast, brightness of display screen adjusting is carried out again after entering abnormal environment luminance area,
Display effect may be will affect, therefore, whether the characteristics of can use navigation programming route, abnormal environment can be entered by prejudging
Luminance area.
For example, determining there is abnormal ring on the guidance path in preset distance or in the predetermined time according to geographical location information
Border luminance area, then correcting initial luminance data according to the type of the abnormal environment luminance area.
In the embodiment of the present invention, classify in advance according to brightness degree to abnormal environment luminance area, if abnormal environment
The brightness degree of luminance area is lower than brightness degree threshold value, then explanation is in dark situation, and camera may carry out image bright
Degree compensation, it is therefore desirable to turn down initial luminance data.
In method provided in an embodiment of the present invention, other environment can also be combined bright on the basis of first environment luminance information
