Based on above-mentioned mobile terminal hardware configuration and communications network system, each embodiment of the method for the present invention is proposed.
Embodiment one
The embodiment of the present invention provides a kind of image processing method, as shown in figure 5, this method can include：
S101, when receiving the picture process instruction to pending picture, by pending picture from RGB domains convert to
YUV domains, pending picture are divided at least one color lump in pending domain.
A kind of image processing method provided in an embodiment of the present invention is suitable under the scene that terminal-pair picture carries out noise reduction.
In the embodiment of the present invention, user using terminal carry out photograph taking when or user in terminal to photo into
During row optimization processing, user clicks shooting push button or optimization button on terminal interface, at this point, terminal receives picture processing
Instruction, terminal obtain pending picture according to picture process instruction.
In the embodiment of the present invention, pending picture is made of at least one color lump, and noise reduction process is carried out to pending picture
It is equivalent to and noise reduction process is carried out at least one color lump.
In the embodiment of the present invention, during picture signal handles (ISP, Image Signal Processing), meeting
The image of original raw forms is transformed into RGB domains reconvert to YUV domains, finally generates a jpg picture by encoding and decoding, originally
Inventive embodiments are handled when RGB domains are transformed into YUV domains, and " Y " represents brightness, that is, grayscale value；" U " and " V " table
What is shown is then coloration, and effect is description colors of image and saturation degree, for the color of specified pixel.
In the embodiment of the present invention, the method that terminal carries out picture processing carries out on YCbCr, and YCbCr is in the world
The part suggested in digital organizing video standard development process as ITU-RBT1601 is YUV in fact by scaling and offset
Reprint；Wherein Y is consistent with the Y meanings in YUV, and Cb, Cr equally refer to color, only different on representation method.
In YUV families, YCbCr is in computer systems using most members, and application field is very extensive, and JPEG, MPEG are adopted
With this form.
Illustratively, as shown in figure 4, the flow of the picture approach in the embodiment of the present invention is：Terminal is by pending picture
After being transformed into YCbCr domains from RGB domains, regional color noise reduction process is carried out to CbCr when carrying out ISP processes.
In the embodiment of the present invention, pending image is transformed into YCrCb skies by terminal using color space convert from rgb space
Between, wherein, pending image from rgb space be transformed into YCrCb spaces after pixel brightness value calculation formula be Y=
0.30*R+0.59G+0.11B, wherein, Y be pending image from RGB be transformed into YCrCb spaces after pixel brightness value.
During the present invention is implemented, since image processing method carries out on YCbCr, therefore, at least one color is in the block every
One color lump is corresponding with Y value (brightness value), Cb values and Cr values (the two has collectively constituted chromatic value).
Specifically, Cr, the Cb of image processing apparatus according to each color pixel in the block, it is corresponding to calculate each color lump
The average value of Cr, Cb, and using the average value as the corresponding Cr values of color lump and Cb values.
S102, in YUV domains, obtain the corresponding at least one brightness value of at least one color lump.
After terminal converts pending picture to YUV domains from RGB domains, terminal will obtain at least one in YUV domains
The corresponding at least one brightness value of a color lump.
In the embodiment of the present invention, terminal obtains the corresponding at least one Y value of at least one color lump, at least one Cb values and extremely
A few Cr value.
S103, when judging that the first color lump belongs to pending color lump, according to corresponding first brightness value of the first color lump, meter
Corresponding first weighted value of the first color lump is calculated, the first color lump is at least one color color lump in the block, and the first brightness value is
The corresponding brightness value of first color lump at least one brightness value.
After terminal gets at least one color lump corresponding at least one brightness value, terminal will judge at least one
Whether color lump belongs to pending color lump, when terminal judges that at least one color the first color lump in the block belongs to pending color lump
When, terminal will calculate corresponding first weighted value of the first color lump according to corresponding first brightness value of the first color lump.
In the embodiment of the present invention, terminal judges whether at least one color lump belongs to and treats successively according at least one brightness value
Color lump is handled, as shown in fig. 6, brightness value includes this 5 brightness value sections of 0-M1, M1-M2, M2-M3, M3-M4, M4-255, when
The first brightness value at least one brightness value is in appointing in this four brightness value sections of 0-M1, M1-M2, M3-M4, M4-255
During one brightness value section of meaning, the brightness value of the first color lump of characterization belongs in non-normal range, and terminal judges the first color lump category
In pending color lump, at this point, terminal calculates corresponding first weighted value of the first color lump according to preset algorithm.
In the embodiment of the present invention, when the first brightness value is in 0-M1 sections, the first color lump of characterization belongs to dark areas；When
One brightness value is in M4-255 sections, and the first color lump of characterization belongs to highlight regions.
Further, when the first brightness value is in M2-M3 sections, the brightness value of the first color lump of characterization belongs to normal range (NR)
It is interior, at this point, terminal does not carry out noise reduction process to the first color lump.
In the embodiment of the present invention, when terminal judges that the first color lump belongs to pending color lump, terminal obtains first respectively
Then corresponding second weighted value of brightness value and the corresponding third weighted value of the first chromatic value are weighed according to the second weighted value and third
Weight values calculate the first weighted value.
In the embodiment of the present invention, the default weighted value calculation formula for calculating the first weighted value is：R=(R_y*W_c)+1-
(W_c), wherein, W_c is the corresponding third weighted value of the first chromatic value, and R_y is corresponding second weighted value of the first brightness value.
In the embodiment of the present invention, terminal determines the second weighted value according to predetermined luminance value and weighted value relationship, such as Fig. 6 institutes
Showing, abscissa is the first brightness value Y of the first color lump, and ordinate is the corresponding second weighted value R_y of the first brightness value, wherein,
The value of M1, M2, M3 and M4 are configured according to specific actual conditions, and the embodiment of the present invention does not do specific restriction.When Y exists
During 0-M1 and M4-255 sections, the value of R_y is 0, and when Y is in M1-M2 or M3-M4 sections, the value of R_y is according to predetermined linear
Relationship is calculated.
