Specific embodiment
The present invention provides a kind of camera based on gps anti-banding noise method to set up and system, for make the purpose of the present invention,
Technical scheme and effect are clearer, clear and definite, and the present invention is described in more detail below.It should be appreciated that it is described herein
Specific embodiment only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is a kind of anti-banding noise method to set up preferred embodiment of camera based on gps of the present invention
Flow chart, as illustrated, comprising:
Step s1, by mobile terminal gps module obtain user present position gps data；
Step s2, described gps data is analyzed, obtains the longitude and latitude degrees of data of user present position；
Step s3, the ac frequency according to described longitude and latitude data acquisition user present position；
Step s4, determine camera anti-banding noise algorithm according to described ac frequency, calculated by described camera anti-banding noise
The parameter of method is taken pictures.
The present invention first passes through the gps data that mobile terminal gps module navigates to user's present position, it is then determined that
The longitude and latitude degrees of data of user present position, so that it is determined that user the country one belongs to or area.According to determined by a state or ground
Area, you can determine ac frequency used, according to ac frequency, enable different cameras anti-banding noise algorithm, thus
Make the photo that photographic head shoots out, eliminate banding noise.
Further, described ac frequency is 50hz or 60hz.Country variant or area, exchange dot frequency used is divided into
Two kinds, can be 50hz or 60hz.
Further, also include before described step s1:
Default setting ac frequency and the corresponding relation of camera anti-banding noise algorithm.
Its camera anti-banding noise algorithm of being adopted of different ac frequencies is different, such as the alternating current of 50 hz
Frequency, the camera that it is adopted anti-banding noise algorithm, with the camera that 60hz ac frequency is adopted anti-banding noise algorithm
Parameter is different, and the compensation dosage of the two exposure is different, can offset due to ac frequency produce banding noise.Specifically,
Camera exposure is that a line a line is exposed, and alternating current lantern festival has the change of light and shade, so the photo coming of breaking forth has bar
Stricture of vagina.And the rudimentary algorithm thought eliminating this striped is the compensation dosage of adjustment exposure, such as when electric light is bright, time of exposure is short
A bit, and when electric light is dark, time of exposure length a bit, thus can make up mutually, thus can't see striped.And it is right
In different ac frequencies, 50hz, 60hz that such as the present invention mentions.Only need to this when adjust the period of change of exposure,
I.e. when ac frequency is for 50hz, adjust time of exposure when 1/50s；And when ac frequency is for 60hz, then exist
Time of exposure is adjusted when 1/60s.So all using similar algorithm for different ac frequencies, simply algorithm
