Fig. 2 shows the schematic diagrames of RGB color, as shown in Fig. 2, rgb color space 200 can be considered as a three-dimensional
Solid space, X-axis, Y-axis and the Z axis of the three-dimensional space respectively indicate the red luma value of red channel, blue channel
The Green brightness value of blue intensity values and green channel, can by determine red channel, blue channel and green channel this
The brightness value of three kinds of Color Channels determines corresponding color in RGB color.
In RGB color, the brightness value in each color channel has 256 grades of intensity, the value range of intensity value be [0,
255], therefore, in RGB color, the stack combinations of the color of three kinds of Color Channels are 16777216 (256 × 256 × 256)
Kind may.
In the related technology, the method for the dominant hue of image is obtained are as follows: terminal is called in central processing unit traversal target image
Each pixel, obtain each pixel the red luma value of red channel, the blue intensity values of blue channel and
The Green brightness value of green channel, statistics obtain the highest red luma value of the frequency of occurrences in red channel, go out in blue channel
The highest Green brightness value of the frequency of occurrences in the existing highest blue intensity values of frequency, green channel, thus most according to the frequency of occurrences
High red luma value, blue intensity values and Green brightness value determines the dominant hue of target image.
The method for obtaining the dominant hue of image in the related technology has the disadvantage that
(1) in the related technology, central processing unit needs to carry out traversal statistics to target image, it will brings biggish calculating
Expense, so as to cause in some cases, such as terminal CPU computation power it is poor in the case where, obtain image
The time of dominant hue is longer.
(2) in the related technology, the dominant hue for the target image that terminal acquires is determined by one group of exact brightness value
, for example, the highest red luma value of the frequency of occurrences that central processing unit counts is 255, Green brightness value is 64, blue
Brightness value is 64, it is determined that the mass-tone is adjusted to brown, therefore, needs 16777216 kinds in RGB color in the related technology
Dominant hue color is determined during color is possible, and the calculation amount of central processing unit is larger, so as to cause the weaker terminal (example of computing capability
Such as mobile phone, tablet computer mobile terminal) dominant hue for obtaining target image is takeed a long time, or, cannot achieve to mesh
The acquisition of the dominant hue of logo image.
(3) in the related technology, the dominant hue of the target image acquired due to terminal is by one group of exact brightness value
Determining, close for dominant hue but different target image, the dominant hue that terminal acquires also is different, at certain
Under a little scenes, such as terminal shows the close but different target image of multiple dominant hues in user interface, since terminal obtains
The dominant hue that obtains is different, thus terminal show these target images when need the color of repeatedly adjustment user interface,
Cause to show that the consistency of user interface is poor.
Fig. 3 shows the schematic diagram in hsv color space, as shown in figure 3, hsv color space can be considered as a cylindrical coordinates
It is that the height z in cylindrical coordinates indicates brightness value, the radius r in cylindrical coordinates indicates intensity value, the radian φ table in cylindrical coordinate
Show hue value.Wherein, the value range of brightness value is [0,1], and the value range of intensity value is [0,1], the value of hue value
Range is [0 °, 360 °].
Hsv color space can intuitively show the relationship between color.For example, lightness, intensity value are identical, form and aspect
Different colors, height having the same and radius in hsv color space, but cylindrical section angle is different, thus this
Two kinds of colors have different shapes in hsv color space；Hue value is identical with intensity value, the different color of lightness,
There is same cross-sectional angle and radius, but height is different, therefore both colors have phase in HSV space in HSV space
Same shape, but there is different height.
Fig. 4 shows the flow chart of the method for the dominant hue for the acquisition image that one exemplary embodiment of the application provides.
As shown in figure 4, can be applied in terminal as shown in Figure 1 come in this way for example, this method comprises:
Step 401, the hue value and intensity value of the pixel in target image are obtained.
Wherein, target image can be deposits in the received image of the icon of the received file destination of terminal, terminal or terminal
Any one image in the image of storage.
When the color standard defaulted in terminal is hsv color space, after terminal acquires target image, target is obtained
The hue value and intensity value of pixel in image；When the color standard defaulted in terminal is RGB color, terminal is obtained
After obtaining target image, brightness value of the pixel in each Color Channel in target image is obtained, by pixel every
Brightness value in a Color Channel is converted into hue value, intensity value and brightness value in hsv color space, to obtain mesh
The hue value and intensity value of pixel in logo image.
Optionally, terminal carries out down-sampled processing to target image, obtain it is down-sampled after image, acquire down-sampled
The hue value and intensity value of the pixel in image afterwards.
Down-sampled is that terminal carries out reduction resolution processes to target image, obtain it is down-sampled after image process.Example
Such as, the resolution ratio of target image is 1000 × 1000 pixels, and down-sampled rate is 1/2, and terminal is according to down-sampled rate, to target image
Carry out it is down-sampled, obtain resolution ratio be 500 × 500 it is down-sampled after image.
Illustratively, terminal can be by way of the progress partiting row sampling of the pixel to target image and/or every column sampling
Carry out down-sampled processing, the application to down-sampled specific implementation without limitation.
After down-sampled processing, terminal only needs to handle the lower image of resolution ratio, and it is entire not need traversal
Target image is handled, and the computing cost of graphics processor is reduced.
Step 402, the distribution situation according to hue value in multiple form and aspect sections determines the mass-tone phase region of target image
Between.
Form and aspect section is the value interval divided according to form and aspect value range preset in terminal.For example, being preset in terminal
Form and aspect value range be universe hue value, the value interval of universe hue value is [0 °, 360 °], then can be by universe hue value
Be divided into 360 parts, respectively [0 °, 1 °], [1 °, 2 °] ..., [358 °, 359 °] and [359 °, 360 °], it is every portion value
Section is form and aspect section.
Optionally, it can be continuously, be also possible to discontinuous between form and aspect section.For example, the color in above-mentioned example
Phase section is the corresponding continuous form and aspect section of universe hue value；The corresponding discontinuous form and aspect section of universe hue value can be with
Be set as [0 °, 1 °], [2 °, 3 °] ..., [357 °, 358 °] and [359 °, 360 °].
Optionally, the value range in form and aspect section may include universe hue value, can not also include universe hue value.Example
Such as, when preset background colour is blue and green, can will with blue approximate form and aspect value interval [100 °, 140 °] and with it is green
Value range of the approximate form and aspect value interval of color [220 °, 260 °] as form and aspect section, the two value ranges are subdivided
For form and aspect section, which can be continuously, is also possible to discontinuous.
After terminal acquires the hue value of the pixel in target image, each hue value is included into corresponding form and aspect area
In, the corresponding hue value number in each form and aspect section is obtained, will include the most form and aspect area of hue value quantity in form and aspect section
Between be determined as mass tone section.
For example, it is 0.5 ° that terminal, which acquires hue value, then 0.5 ° of hue value is included into the form and aspect section of [0 °, 1 °]
In, if in the form and aspect section of [0 °, 1 °] only including 0.5 ° of this hue value, then terminal determines in the form and aspect section of [0 °, 1 °]
The hue value quantity for including is 1.
Step 403, the distribution situation according to intensity value in multiple saturation degree sections determines that the master of target image is full
With degree section.
Saturation degree section is the value interval divided according to saturation degree value range preset in terminal.For example, in terminal
Preset saturation degree value range is universe intensity value, and the value interval of universe intensity value is [0,1], then can be by universe
Hue value is divided into 10 parts, respectively [0,0.1], [0.1,0.2] ..., [0.8,0.9] and [0.9,1], it is every portion value
Section is saturation degree section.
Optionally, it can be continuously, be also possible to discontinuous between saturation degree section.For example, in above-mentioned example
Saturation degree section is the corresponding continuous saturation degree section of universe intensity value；Universe intensity value is corresponding discontinuous full
With degree section can be set as [0,0.1], [0.2,0.3] ..., [0.7,0.8] and [0.9,1].
Optionally, the value range in saturation degree section may include universe intensity value, can not also include universe saturation
Angle value.For example, application developer is not intended to for the color of user interface to be adjusted to, saturation degree is excessively high or saturation degree is too low
Saturation degree section can be arranged in saturation degree value range [0.3,0.7] in color.
After terminal acquires the intensity value of the pixel in target image, each intensity value is included into corresponding full
In degree section, the corresponding intensity value number in each saturation degree section is obtained, will include intensity value number in saturation degree section
It measures most saturation degree sections and determines to be main saturation degree section.
For example, it is 0.5 ° that terminal, which acquires intensity value, then 0.5 ° of hue value is included into the form and aspect section of [0 °, 1 °]
In, if in the form and aspect section of [0 °, 1 °] only including 0.5 ° of this hue value, then terminal determines in the form and aspect section of [0 °, 1 °]
The hue value quantity for including is 1.
Step 404, inquiry obtains the corresponding main saturation of the corresponding mass tone value in mass tone section and main saturation degree section
Angle value.
The corresponding hue value in each form and aspect section, the corresponding intensity value in each saturation degree section, for example, [0 °,
1 °] the corresponding hue value in form and aspect section be 0.5 °, the corresponding intensity value in saturation degree section of [0,0.1] is 0.05.
Terminal obtains the corresponding hue value in mass tone section according to inquiry, using the corresponding hue value in mass tone section as master
Hue value, inquiry obtain the corresponding intensity value in main saturation degree section, using the corresponding intensity value in pearl saturation degree section as master
Intensity value.
Step 405, the dominant hue of target image is determined according to mass tone value and main intensity value.
Terminal can determine the face in HSV space according to mass tone value, main intensity value and preset brightness value is obtained
Color, to obtain the dominant hue of target image.
In conclusion in the embodiment of the present application, by obtaining the hue value and intensity value of the pixel in target image,
Distribution situation according to hue value in multiple form and aspect sections distribution situation and intensity value in multiple saturation degree sections, it is main
Mass tone section and main saturation degree section are determined in the main saturation degree section in form and aspect section, so that inquiry obtains mass tone section pair
The corresponding main intensity value of mass tone value and main saturation degree section answered, and then the dominant hue of target image is obtained, due to master
Hue value and main intensity value are according to the mass tone section and main saturation degree section acquired by tabling look-up, terminal
It does not need accurately to acquire the highest hue value of the frequency of occurrences and intensity value, therefore reduces the computing cost of terminal,
The time for obtaining the dominant hue of image is reduced to a certain extent.
In the embodiment of the present application, by the way that by the corresponding hue value in each form and aspect section, each saturation degree section corresponds to one
A intensity value, can make hue value similar in hue value correspond to same hue value, and intensity value similar in intensity value is corresponding
Same intensity value, since the dominant hue of target image is determined according to mass tone value and main intensity value, at certain
Target image similar in dominant hue can be made to acquire identical dominant hue in a little situations, so that terminal is in display different target
When the dominant hue of image, the consistency of display dominant hue is improved.
Optionally, in the embodiment of the present application, by carrying out down-sampled processing to target image, obtain it is down-sampled after figure
Picture, terminal obtain it is down-sampled after image in pixel hue value and intensity value, to acquire target image
Dominant hue reduces the calculation amount of terminal, reduces to a certain extent since the resolution ratio of the image after down-sampled is lower
Obtain the time of target image dominant hue.
Fig. 5 shows the flow chart of the method for the dominant hue for the acquisition image that one exemplary embodiment of the application provides.
As shown in figure 5, this method can be applied in terminal as shown in Figure 1, this method comprises:
Step 501, graphics processor carries out down-sampled processing to target image, obtain it is down-sampled after image.
The process that graphics processor carries out down-sampled processing to target image can refer to the step 401 in Fig. 4 embodiment,
This is not repeated them here.
Illustratively, graphics processor carries out down-sampled processing to target image according to down-sampled rate preset in terminal,
For example, when the down-sampled rate of length and width is 1/2, it is down-sampled if the resolution ratio of target image is 1000 × 1000
The resolution ratio of image afterwards is 500 × 500, sets point for 500 × 500 for viewport (rasterisation number) in graphics processor
Resolution.When the display of the operating system of terminal is driven to open graphic library (Open Graphics Library, OpenGL),
Rasterization process is carried out to reference picture using glViewport instruction；When the display of the operating system of terminal is driven to metal
(Metal) when, rasterization process is carried out to reference picture using glViewport instruction.
Step 502, graphics processor obtain it is down-sampled after image in each pixel every kind of face in RGB color
Brightness value in chrominance channel.
The color standard defaulted in the operating system of usual terminal is RGB color, and graphics processor acquires drop
The red luma value, Green brightness value and blue intensity values of each pixel in image after sampling.
Illustratively, it is bright in red to acquire the purple pixel point that coordinate in reference picture is (1,1) for graphics processor
Angle value is 128, and Green brightness value is 0, blue intensity values 128.
Step 503, brightness value of the graphics processor according to each pixel in each color channel is calculated each
The hue value and intensity value of pixel.
Graphics processor is acquiring brightness value of each pixel in RGB color in each color channel
Afterwards, it needs to execute the processing that RGB color turns hsv color space to the brightness value in each color channel, that is, graphics processor
According to preset algorithm, brightness value of the pixel each in reference picture in RGB color in each color channel is turned
Turn to the hue value and intensity value in hsv color space.
Illustratively, graphics processor acquires the red luma value for the pixel that coordinate in reference picture is (1,1)
It is 128, Green brightness value is 0, and after blue intensity values are 128, by preset algorithm, the hue value for obtaining the pixel is
300 °, intensity value 1.
Step 504, preset form and aspect value range is divided into n form and aspect section by graphics processor, and n is positive integer.
Graphics processor is divided into n form and aspect section according to preset form and aspect value range, by the form and aspect value range.It can
Choosing, be continuously, or, being discontinuous between n form and aspect section between n form and aspect section；Preset form and aspect value range
For universe hue value, or, preset form and aspect value range is not universe hue value.
