Therefore, can adjust the saturation degree that shows image adaptively according to environmental light brightness according to display device and the display packing of the embodiment of the invention.Preferably, adjust saturation degree and the brightness that shows image adaptively simultaneously according to environmental light brightness.
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.
Usually, the view data of the image to be displayed that obtains is the demonstration data of (R0, G0, B0) form, wherein, R0 is the red sub-pixel value of display pixel, G0 is the green sub-pixels value of display pixel, and B0 is blue subpixels value R0, G0, the B0 value in 0 to 255 scope for example of display pixel.
Certainly, the invention is not restricted to this, the view data of the image to be displayed that obtains can be the demonstration data of (R, G, B) form, and wherein, R is red values and 0≤R≤1, and G is green values and 0≤G≤1, and B is blue values and 0≤B≤1.
Further, the view data of the image to be displayed that obtains can also for (H, S, L) the demonstration data of form, wherein, H is chromatic value and 0≤H≤360 °, L is brightness value and 0≤L≤1, S is intensity value and 0≤S≤1.
At step S115, obtain ambient light intensity.Should be understood that step S115 and step S110 can carry out simultaneously, perhaps step S115 can carry out before step S110.
At step S120, for each display pixel, according to the function of the current brightness of ambient light intensity and this display pixel, determine the brightness of expectation.Can adopt the method for existing adjustment display brightness to determine the expectation brightness of each display pixel.
At step S130, for each display pixel, according to the function of the current saturation degree of ambient light intensity and this display pixel, determine the saturation degree of expectation.
Next, with reference to figure 2, Fig. 2 is the process flow diagram that illustrates according to the exemplary method of the expectation saturation degree of the pixel in definite image to be displayed of the embodiment of the invention.In the following description, the demonstration data of R, G, B form are normalized values, and wherein, R is red values and 0≤R≤1, and G is green values and 0≤G≤1, and B is blue values and 0≤B≤1.Under the situation of view data for the demonstration data of (R0, G0, B0) form of the image to be displayed that obtains, it need be carried out the normalization conversion to be transformed to (R, G, B) form.
At step S1310, the demonstration data of R, G, B form are converted into H, L, S form, wherein, H is chromatic value and 0≤H≤360 °, and 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, according to the function of the current saturation degree S of ambient light intensity and this display pixel, determine the expectation saturation degree S ' of this display pixel.Should be appreciated that step S1320 is optional.
As example, the function of the current saturation degree S of ambient light intensity and display pixel can be S '=1-(1-S)
nPreferably, select value and n＞0 of n according to ambient light intensity.
Under the situation of n＞1, the expectation intensity value is greater than current intensity value; Under the situation of n=1, the expectation intensity value equals current intensity value; Under the situation of 0＜n＜1, the expectation intensity value is lower than current intensity value.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.
The described parameter n that wishes in the saturation function can be set as required, in Fig. 4, provide n different value (for example, n=1, n=2, n=3, n=4, the curves of the expectation saturation function in the time of n=5).
As example, an ambient light intensity threshold value can be set, when the ambient light intensity that obtains is higher than this ambient light intensity threshold value, determine to wish improve the saturation degree of image to be displayed, this moment, n was set to value greater than 1 as required.
As another example, two ambient light intensity threshold values can be set: first environment intensity threshold and second environment intensity threshold, the first environment intensity threshold is less than the second environment intensity threshold.For example, when the ambient light intensity that obtains is lower than the first environment intensity threshold, think that surround lighting very a little less than, for example the occasion that in night do not turn on light in the room in the case, may need to turn down the saturation degree of image to be displayed, in order to reduce the stimulation to eyes.On the other hand, when the ambient light intensity that obtains is higher than the second environment intensity threshold, think that surround lighting is very strong, for example the strong occasion of outdoor illumination in the case, may need to heighten the saturation degree of image to be displayed, in order to improve viewing effect.
In the case, when the ambient light intensity that obtains is higher than this second environment intensity threshold, determine to wish improve the saturation degree of image to be displayed, this moment, n was set to value greater than 1 as required; Yet, when the ambient light intensity that obtains is lower than this first environment intensity threshold, determine to wish reduce the saturation degree of image to be displayed, this moment, n was set to value less than 1 as required
As another example, ambient light intensity threshold value more than two can be set, 5 ambient light intensity threshold values for example are followed successively by according to from low to high order: first environment intensity threshold, second environment intensity threshold, the 3rd ambient light intensity threshold value, border, Fourth Ring intensity threshold, border, five rings intensity threshold.For example, in the case, can select the value of n as shown in the tablely.
| The ambient light intensity that obtains＜first environment intensity threshold | n＝1/4 |
| Ambient light intensity＜second environment the intensity threshold of first environment intensity threshold＜obtain | n＝1/2 |
| Ambient light intensity＜the 3rd ambient light intensity threshold value of second environment intensity threshold＜obtain | n＝1 |
| Ambient light intensity＜border, the Fourth Ring intensity threshold of the 3rd ambient light intensity threshold value＜obtain | n＝2 |
| Ambient light intensity＜border, the five rings intensity threshold of border, Fourth Ring intensity threshold＜obtain | n＝3 |
| The ambient light intensity that obtains＞border, five rings intensity threshold | n＝4 |
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)
Adjust in hope under the situation of brightness of pixel, in step S1320, also obtain the hope brightness L ' of display pixel.Then, in step S1330, the demonstration data of H, L ', S ' form are converted into R ', G ', B ' form, no longer give unnecessary details at this.
Next, before showing image, still need normalized excitation value with (R ', G ', B ') form to be transformed to corresponding display pixel value (R0 ', G0 ', B0 '), for example, display pixel value in 0～255 scope is carried out the image demonstration for display or display unit.
Then, at step S140, for each display pixel, show according to determined expectation saturation degree.It should be noted that under the situation of execution in step S120, in step S140, according to determined expectation saturation degree and expectation brightness, carry out the demonstration of this display pixel
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 hope saturation curves of n when getting different value.As shown in Figure 4, n=2 no matter, n=3, n=4 or n=5, wishing in the saturation curves that accordingly suppose second saturation degree greater than first saturation degree, described first saturation degree is wished to be adjusted to first and wished saturation degree, described second saturation degree is wished to be adjusted to second and is wished saturation degree, and described second wishes that saturation degree still wishes 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, saturation degree after the adjustment of each pixel still keeps original magnitude relationship, under the situation of the saturation degree that improves image to be displayed, only be to have promoted color vividness on the whole, make color more gorgeous.
Although described the present invention above under the application scenarios of the saturation degree that improves display frame, yet the invention is not restricted to this, the present invention also is applied to reduce under the application scenarios of saturation degree of display frame certainly.
