Specific implementation
Display device and display packing thereof according to the embodiment of the invention are described below with reference to accompanying drawings.Be to be understood that: the embodiments described herein only is illustrative, and should not be interpreted as limiting the scope of the invention.
According to the saturation degree that display device and the display packing of the embodiment of the invention can be adjusted display screen adaptively according to the type of content to be displayed (image), preferably, also adjust the brightness of display screen adaptively.
Some contents and the corresponding desired display effects thereof that show in present display device have been shown in the table 1.However, it should be understood that content displayed never is limited to following content in display device.
Fig. 1 is the process flow diagram that illustrates according to the display packing 100 of the embodiment of the invention.As shown in Figure 1, the display packing 100 according to the embodiment of the invention begins at step S101.
At step S110, obtain the view data of image to be displayed.The view data of the image to be displayed that usually, obtains is the demonstration data of R, G, B form.
At step S120, judge whether the image parameter of described image to be displayed satisfies predetermined condition.For example, can obtain the image parameter of described image to be displayed according to the current type of application of just moving, perhaps can obtain the image parameter of described image to be displayed according to the view data of the image to be displayed that obtains.
Preferably, described image parameter is image type or content type.For example, when the current application program of just moving is video playback application programs such as media player, can determine that the image type of described image to be displayed or content type are video.For example, be picture such as picture editor when handling application program in the current application program of just moving, can determine that the image type of described image to be displayed or content type are picture or photo.For example, when the current application program of just moving is document processing application programs such as document editor, can determine that the image type of described image to be displayed or content type are text or e-book.
As above shown in the table 1, wish when showing photo, picture, video or recreation, to improve the saturation degree of shown image, make the shown coloured image more lively.In the case, preferably, described predetermined condition is: the image type of described image to be displayed is at least a in photo, picture, video pictures, the recreation.
On the other hand, preferably, described image parameter is the whole saturation degree (that is the average staturation of pixel) of image.For example, can extract or generate the whole saturation degree of described image to be displayed according to the view data of the image to be displayed that obtains.In the case, preferably, can preestablish at least one saturation degree threshold value, in order to determine whether it is adjusted saturation degree and selects suitable saturation degree to adjust function according to the rank of the whole saturation degree of the image to be displayed that generates, this will specify below.In the case, preferably, described predetermined condition is: the whole saturation degree of described image to be displayed is higher than predetermined threshold.
More above-mentioned two kinds of situations, according to the whole saturation degree of image judge whether needs adjust saturation degree method may be more flexible.For example, opening under the situation of webpage, when mostly being text data greatly on webpage, the whole saturation degree of current demonstration image is lower than described predetermined threshold, thereby judgement need not to adjust saturation degree in the case; Yet on the other hand, during the display color picture, the whole saturation degree of current demonstration image is higher than described predetermined threshold on webpage, thereby judges in the case and need to adjust saturation degree.Again for example, under the situation of reading the pdf format file, when showing according to 70% displaying ratio, picture in the current display page only accounts for 1/4 size of the page, in the case, the whole saturation degree of current demonstration image is lower than described predetermined threshold, thereby judgement need not to adjust saturation degree; Yet transferring big displaying ratio to 200% even when higher, described picture may account for the page 2/3 in addition more, the whole saturation degree of current demonstration image is higher than described predetermined threshold, thereby judges and need to adjust saturation degree.
Although provided two concrete examples of image parameter and predetermined condition in the above, it should be understood that to the invention is not restricted to this that those skilled in the art can make up above-mentioned two kinds of methods according to actual needs or other image parameter and predetermined condition are set.
When described predetermined condition was satisfied in step S120 judgement, this display packing 100 advanced to step S130.
At step S130, adjust the saturation degree of described image to be displayed.
Next, with reference to figure 2, Fig. 2 is the process flow diagram that illustrates according to the exemplary method of the saturation degree of the adjustment image to be displayed of the embodiment of the invention.In the following description, the demonstration data of R, G, B form all have been transformed to normalized values.
At step S1310, the demonstration data of R, G, B form are converted into H, L, S form, wherein, R is red values and 0≤R≤1, G is green values and 0≤G≤1, and B is blue values and 0≤B≤1, and H is chromatic value and 0≤H≤360 °, L is brightness value and 0≤L≤1, and S is intensity value and 0≤S≤1.
Can utilize following transformation for mula that the demonstration data of R, G, B form are converted into H, L, S form.
M＝max(R，G，B)
m＝min(R，G，B)
C＝M-m
H＝60°×H′
Wherein, M is the maximal value among R, G, the B, and m is the minimum value among R, G, the B, and C is the poor of maximal value among R, G, the B and minimum value, and H ' is the chromaticity transformation intermediate value, and mod represents to get remainder.
In step S1320, adjust function according to predetermined saturation degree, adjust the intensity value S of this pixel to adjusting intensity value S '.
As example, described saturation degree is adjusted function can be S '=1-(1-S)
nPreferably, adjust in the function n＞0 in described saturation degree.
Under the situation of n＞1, the intensity value after the adjustment is greater than the intensity value before adjusting; Under the situation of n=1, saturation degree is not adjusted; Under the situation of 0＜n＜1, the intensity value after the adjustment is lower than the intensity value before adjusting.
In other words, improve in hope under the situation of saturation degree of display frame, select n＞1; On the other hand, reduce in hope under the situation of saturation degree of display frame, select 0＜n＜1.
Determining under the situation of needs adjustment saturation degree according to image type or content type, the parameter n in the described saturation degree adjustment function can be set as required, (for example in Fig. 4, providing the different values of n, n=1, n=2, n=3, n=4, the saturation degree in the time of n=5) is adjusted curve.
Under the situation of determining needs adjustment saturation degree according to the whole saturation degree of current demonstration image, can arrange or select the parameter n in the described saturation degree adjustment function according to the whole saturation degree of current demonstration image.To be the aforesaid situation that at least one saturation degree threshold value is set of the concise and to the point description of example a saturation degree threshold value to be set and three saturation degree threshold values are set below.
When a saturation degree threshold value was set, when the whole saturation degree of current demonstration image was higher than this saturation degree threshold value, determining needed to adjust saturation degree, and the parameter n in the saturation degree adjustment function as described in arranging as required as according to the situation of image type.
Under the situation that three saturation degree threshold values are set, suppose: the first saturation degree threshold value is higher than the second saturation degree threshold value, and the second saturation degree threshold value is higher than the 3rd saturation degree threshold value.
For example, when the whole saturation degree of current demonstration image is higher than the 3rd saturation degree threshold value and is lower than the second saturation degree threshold value, can be described the parameter n that adjusts in the function of saturation degree be set to 4; When the whole saturation degree of current demonstration image is higher than the second saturation degree threshold value and is lower than the first saturation degree threshold value, can be described the parameter n that adjusts in the function of saturation degree be set to 3; When the whole saturation degree of current demonstration image is higher than the first saturation degree threshold value, can be described the parameter n that adjusts in the function of saturation degree be set to 2.
Yet, the invention is not restricted to above-mentioned situation, those skilled in the art can arrange the saturation degree threshold value of other quantity as required, and the value that described saturation degree is adjusted the parameter n in the function can correspondingly be set.It should be noted that described parameter n is not limited to integer, and can be the real number greater than 0.
Next, at step S1330, the demonstration data of H, L, S ' form are converted into R ', G ', B ' form.
C＝(1-|2L-1|)×S′
X＝C(1-|H′mod2-1|)
(R′，G′，B′)＝(R
1+m，G
1+m，B
1+m) (2)
Next, before showing image, still need the normalized excitation value of R ', G ', B ' form is transformed to corresponding display pixel value, for example, the display pixel value in 0～255 scope is carried out the image demonstration for display or display unit.
Then, at step S140, the demonstration data that utilization has been adjusted after the saturation degree are carried out the image demonstration.
At last, the display packing according to the embodiment of the invention finishes at step S199.
The saturation degree that Fig. 4 shows example adjust function S '=1-(1-S)
nIn the saturation degree of n when getting different value adjust curve.As shown in Figure 4, n=2 no matter, n=3, n=4 or n=5, adjust in the curve in corresponding saturation degree, suppose second saturation degree greater than first saturation degree, described first saturation degree is adjusted to first and adjusts saturation degree, described second saturation degree is adjusted to second and adjusts saturation degree, and described second adjusts saturation degree still adjusts saturation degree greater than described first.On the other hand, as shown in Figure 4, when the not supersaturation of initial saturation (being that initial saturation is less than 1) of the pixel of image to be displayed, also not supersaturation of the saturation degree after the adjustment (namely less than 1).
In other words, the monotonicity of saturation degree does not change.Because the monotonicity of saturation degree does not change, therefore, for the numerous pixels in the image to be displayed, the saturation degree after the adjustment of each pixel still keeps original magnitude relationship, and only is to have promoted color vividness on the whole, makes color more gorgeous.
