Embodiment two
When watching video, people are easy that more gorgeous by color, brightness is higher, the faster persons or things of movement attract,
So more attentions can be placed on these persons or things, or even the things and background of surrounding can be ignored, for example, picture
Surrounding is the branches and leaves of green, and centre is many red roses, we prefer to highlight gorgeous red rather than rendering green.
1. human eye vision atmosphere extends
The visual angle very little of human eye, if calculated with observable standard, the visual angle of human eye is about 150 degree, but by seeing
Clearly standard, visual angle just only have 5 degree or so, Just because of this, artificial expansion field range, must roll commonplace turn
Dynamic eyeball, left and right are looked forward to, and must rotate a head portion sometimes.
The visual range of people is visus acris area, i.e. central field of vision within 10-15 °, to the color and detail section of image
Resolution capability it is most strong, the information such as figure can be correctly identified within 20 °, be effective field of view, although 20-30 ° of eyesight and color discrimination
Ability starts to reduce, but more sensitive to action message, and eyesight just declines much except 30 °.
For people when carrying out human-computer interaction, people is different from the relative position of equipment, and the image or video that eye-observation arrives are drawn
It face also can be different.Like when film is watched by cinema, its visual angle of the spectators of different location is different, and viewing impression can not yet
Together.Under normal circumstances, it needs just see whole pictures clearly by rotation eyeball or twisting neck apart from the closer spectators of screen,
Apart from the farther away spectators of screen then it is easy to see that entire picture, however too far distance will affect clarity again, and deviate glimmering
The spectators of curtain see that the things in picture can have deformation in varying degrees.
The invention proposes positive visual angle atmosphere to set off by contrast, to protrude the emphasis things of attraction onlooker's eyeball of video frame.It is so-called
" positive visual angle " is at people and interactive device in certain relative position, and image or video from human eye angle can reach
Optimal effect.It is the positive visual angle figure of human eye shown in Fig. 6, the opposite position of people and interactive device has clearly been marked in the front view
It sets, wherein D indicates vertical range of the human eye apart from human-computer interaction device, and intersection point is in the man-machine friendship that width is W and height is H
At the center of mutual equipment, the actual size of D value varies with each individual, and standard is the ocular comfort of onlooker, it is seen that image or video
Clearly.Elliptical region in figure is the effective coverage of human eye, and human eye is more sensitive to action messages such as the colors in the region,
Size determines that angle [alpha] is generally at 20-30 ° by the effective field of view angle [alpha] of human eye and human-computer interaction device's distance D and human eye
Between.
The effective field of view in front view is it has been determined that it is to stop that people, which have a big chunk time when watching picture or video,
Stay in effective field of view, be either still all for picture or video itself angle from comfortable angle, clear angle as
This.Therefore the expression in the eyes of atmosphere can be carried out in effective field of view by the size reduction to effective field of view of image or video script
Or vision lures and draws color extraction, wherein vision, which lures, draws the mass-tone that color generally as attracts eyeball.If human eye is apart from man-machine friendship
The distance D of mutual equipment is bigger or the width W and height H of human-computer interaction device are smaller, then the effective field of view of onlooker can be with
The edge of image or video, the even more than size of image or video are touched, effective field of view at this time is then considered as entirely
Image or video.
In order to give top priority to what is the most important, the algorithm for drawing color is lured the invention proposes a kind of extraction vision.Fig. 7 show picture in its entirety and shows
It is intended to, wherein picture middle section is to extract and judge that the vision in the frame picture lures the region for drawing color, which can be located at figure
The intermediate region of piece either in the range of human eye can be faced, is that human eye is also easiest to the region paid attention at first, extracts mass-tone
The width of region distance image edge is W.
2. determining the section region mass-tone HSV
As shown in Fig. 8 to Figure 13 B, the present invention, which is extracted vision using following methods and lured, draws color, and then to image or view
Frequency carries out atmosphere rendering.
(A) it delimit and extracts mass-tone region (201)；
(B) it determines that vision lures and draws color region (202)；
(C) it determines that vision lures to draw color and extract (203)；And
(D) verification vision, which lures, draws color (204)；
(E) it is lured according to vision and draws color progress atmosphere rendering (205).
After determining that vision lures and draws color region, in the step (C), then the rgb pixel square in the region can be extracted
Battle array can be used the mode described above every N row M column and acquire rgb pixel matrix to improve efficiency.By collected rgb pixel
Matrix is all converted to HSV matrix, and HSV histogram is then calculated.Under normal conditions, bright-colored, brightness is higher and reaches
Things to certain amount (i.e. range is larger) is easiest to attract eyeball.The present invention sets saturation degree S-threshold, brightness V-
Threshold and number percent Ratio-threshold lures the three elements for drawing color as examination vision.From HSV histogram
All sections HSV greater than three elements are counted, if without the section for meeting three elements, then it represents that the frame picture is without especially prominent
A certain things out, i.e. no visual, which lure, draws color.If the section the HSV number for meeting the three elements is greater than zero, select a fairly large number of
It is lured as vision and draws color section, and record the quantity MaxNum in the section HSV comprising picture midpoint.
2.1, which determine that vision lures, draws color region
In the step (B), the vision of extraction is lured and draws color region further division, the purpose is to lure vision to draw color
Region refinement, and lured according to the vision in the refinement region of statistics and to draw color information to correspond to and be shown in the lamp bead that atmosphere renders, from
And atmosphere (including brightness, color, colour temperature etc.) rendering more accurately can be carried out to mass-tone.
There are many kinds of the modes of mass-tone refinement, and specific division mode is needed according to the image or video being specifically rendered
Depending on.Figure 10 A to Figure 10 B shows three kinds of division modes, and mass-tone region division is all four pieces by these three modes, may be used also certainly
To be divided into two pieces, three pieces or more muti-piece.The present embodiment is mainly illustrated for four pieces.
Figure 10 A be mass-tone regional center line be line of demarcation by mass-tone region be divided into upper left UpLeft, lower-left LowLeft,
Upper right UpRight and tetra- pieces of bottom right LowRight.Figure 10 B is then to draw mass-tone region using the diagonal line in mass-tone region as line of demarcation
It is divided into Up, lower Low, left Left, tetra- pieces of right Right.Above two division mode application range is wider, to most images or view
Frequency is applicable in, and since the corresponding lamp bead position of two different division modes is different, rendering effect also can be different.Figure 10 C be
Remove what mass-tone region middle section obtained on the basis of Figure 10 B, such division mode is primarily adapted for use among image or video
Under the compositions such as the colour brightness at position are fixed or the lesser situation of variation, for example occur a turntable in image, works as turntable
The color component part of intermediate region is constant when rotation, and peripheral regions are constantly to change, and rotation speed is faster
The color change of its surrounding is faster.The size at position can be determined by predefined mode among Figure 10 C, can also be passed through
Image procossing and the mode real-time monitoring of calculating determine.
After determining that mass-tone divides region, then the region of division is handled, for processing method is described in detail, herein
By taking Figure 10 A as an example.
It has obtained extracting vision and luring by Fig. 9 flow chart drawing the section mass-tone HSV in color region, then count respectively in next step
The quantity of point of tetra- area distributions of LU, LD, RU, RD in the section mass-tone HSV, be denoted as respectively ULNum, LLNum, URNum,
LRNum.They meet formula (1), and the size of four variables embodies distribution situation of the mass-tone in four regions, quantity more it is big then
The number of mass-tone in this region is more, which is then easier to arouse attention.
ULNum+LLNum+URNum+LRNum=MaxNum (1)
It, can be by calculating the number of dominant colors in each region and the ratio of total quantity MaxNum for the prominent mass-tone region of emphasis

2.2, which determine that vision lures, draws color
The left margin (median or right margin) in tri- sections H, S, V in section can be artificially chosen under normal conditions as master
Color HSV value, is then converted into rgb value.This way is fairly simple, but true in the HSV value artificially assert not necessarily picture
Real existing value, easily causes color difference.In addition, the accuracy of this way is influenced by HSV siding-to-siding block length, siding-to-siding block length is got over
Big then to HSV value influence is bigger, to influence on the mass-tone rgb value being finally calculated bigger.To avoid the above problem, this
Invention is carried out by the way of directly choosing picture true colors itself.Since HSV picture element matrix is the rgb pixel square in picture
What battle array was converted to, therefore the HSV of necessary being need to be only chosen, it is then converted into RGB.Mass-tone area is had determined above
Between, and vision lures and draws color one and be scheduled in mass-tone section, therefore the HSV value for meeting mass-tone section need to be only found out in picture.
But vision is lured draw the color that color is more heavily weighted toward high saturation, high brightness herein, therefore added S value when looking for HSV and meet
Median and V value greater than mass-tone section S are greater than the two conditions of the median of mass-tone section V.High saturation is so just taken into account
Two degree, high brightness and picture true colors aspects.If meeting condition there is no HSV in picture, saturation degree can choose
With brightness one of them, look in picture the HSV value of saturation degree in all the points for meeting mass-tone section maximum (brightness is maximum).Such as

The method for demonstrate,proving mass-tone, this method are built upon on the basis of there is vision to lure and draw color section its former frame or former frames.
For example, if there is a certain frame vision, which to lure, draws the section color HSV, that five frame after it first have into
The imitative binary conversion treatment of row, binaryzation here is not traditional binaryzation.Traditional binaryzation is by the pixel on image
The gray value of point is set as 0 or 255, and whole image, which shows, significantly only has black and white visual effect.Two are imitated in the present invention
Value is the threshold value comparison method by means of traditional binaryzation, it handle image the result is that the phase of black and a certain close colour
In conjunction with.Traditional binaryzation sets a certain threshold value T, and the pixel value greater than T is set as 255, and the pixel value less than T is set as 0.Imitative binaryzation
Threshold value be that there is the section HSV of certain siding-to-siding block length, the pixel value for meeting the section keeps its HSV constant, outside section
The all black of pixel value, that is, brightness V is 0.It has just obtained a width in this way there was only the point in mass-tone section being colour, remaining point is all
The picture of black.Then statistics mass-tone points are carried out to this special picture and measures MaxNum, and determining vision is called to lure
Draw the algorithm in color region and determine that vision lures and draws color.
It is as shown in figure 12 to extract mass-tone region specific flow chart.Firstly, detection previous frame or upper five frame whether there is vision
It lures and draws color section, and if it exists, imitative binary conversion treatment is then carried out in the manner described above, is then determined that vision lures and is drawn color region,
It determines that vision lures and draws color, and vision is lured and draws color region and shows.If detection discovery previous frame or upper five frame are not deposited
It is lured in vision and draws color section, then needed in such a way that said extracted vision of the present invention lures and draws color section, redefined and extract area
The vision in domain, which lures, draws color section, then determines that vision lures and draws color region, determines that vision lures and draw color, and lure vision and draw color institute
It is shown in region, if after redefining extraction, can not still find vision and lure and draw color section, then prove that no visual lures and draw
Color then needs to extract mass-tone in the way of embodiment one kind and carries out atmosphere rendering.
