The plurality of specific time and space modes may include: a specific time and space 1: representing "the sunset of the Danshui River estuary in the autumn of 2011"; a specific time and space 2: representing "the sunset of the Yellow River (Lanzhou City) in the autumn of 2011"; specific time and space 3: representative "Sunrise of the Alps on January 1, 2011"; specific time and space 4: represents "Sunrise of Alishan in Chiayi on January 1, 2011"; Specific time and space 5: Represents the "Moon of the Penghu in the Mid-Autumn Festival of 2011."

The actual case will be used to illustrate the action process of this case:

First, in the first embodiment, the plurality of light-emitting elements (11A, 11B, 11C, 11D, 11E, 11F, 11G) may be red light (assumed to be light-emitting elements 11A and 11B), white light (assumed to be light-emitting elements) 11C and 11D), yellow light (assumed to be light-emitting elements 11E and 11F) and infrared light (assumed to be light-emitting element 11G).

The contextual process for the specific time and place of each specific time-space data 31:

Take the specific time and space 1 for the "Sunset of the Danshui River estuary in the autumn of 2011". This is to set up the camera against the setting sun. Take a picture of the tenth minute before the sunset of the Tamsui River estuary in 2011, assuming every ten seconds. One, you can get 60 images of this to observe the color of the sunset (the sunset) (of course, this time and the number of sheets can be increased or decreased). The circular area of each image (i.e., day or month, corresponding to the central area P1 of the illumination device 10) can calculate an average RGB value.

The plurality of light-emitting elements (11A, 11B, 11C, 11D, 11E, 11F, 11G) for each group of light-emitting devices 11 may have a combination of the following Table 1:

Of course, the combination of Table 1 is only an example, actually different wavelengths and different Any combination of the plurality of light-emitting elements (11A, 11B, 11C, 11D, 11E, 11F, 11G) of RGB is not required to be loaded, and each combination produces a combined light of different RGB values.

That is, when any of the specific spatio-temporal data 31 is selected, the processing device 40 activates the complex array illumination device 11 and corresponds to a plurality of track points of the CIE chromaticity diagram at each time point of the context change process ( x , y ), the instantaneous calculation of the RGB values of each combined ray corresponds to a plurality of trajectory points ( x ', y ') of the CIE chromaticity diagram, and obtains a point-by-point cumulative error from the trajectory point ( x , y ) The track point ( x ', y ') of the minimum distance, and the combination of the light-emitting elements corresponding to the track point ( x ', y ') is illuminated, so as to achieve the best imitation of the date and time of the different time and place The contextual lighting effect of the cloud.

By the foregoing comparison process, the processing device 40 may pre-establish a corresponding plurality of combined light CIE data 31B for the specific space-time CIE data 31A of the plurality of pens, and store the data in the database 30 (see the Three B pictures).

In addition, the part to be specifically described here is about the color information description of color video images. There are various color coordinate systems available for use. CIE (Commission Internationale de l'clairage) is an international organization. Specifically designed to set the standard of luminosity and color, CIE proposed the UVW homochromatic proportional (UCS) color coordinate system in 1960. Its biggest feature is that the color change ratio is almost equal in color coordinates. In addition to the definition of Trichromatic Coefficient, CIE defines the red wavelength as R(λ)=700nm, the green wavelength is G(λ)=546.1nm, the blue wavelength is B(λ)=435.8nm, and RGB is three. The amount of light in the grayscale value of a point, the tristimulus values of the color in the CIE color space are X, Y, and Z, which can correspond to the relationship between red, green, and blue, that is: X = A ₁₁ R + A ₁₂ G + A ₁₃ B ; Y = A ₂₁ R + A ₂₂ G + A ₂₃ B ; Z = A ₃₁ R + A ₃₂ G + A ₃₃ B ; x = X / ( X + Y + Z ); y = Y /( X + Y + Z ); where A _ij is a parameter related to the camera, and the relevant settings are: A ₁₁ + A ₁₂ + A ₁₃ =1, A ₂₁ + A ₂₂ + A ₂₃ =1, A ₃₁ + A ₃₂ + A ₃₃ =1.

For the RGB and CIE coordinate comparison results of the image (in this case, the image of the plurality of light-emitting devices 11 or the plurality of images obtained by continuous shooting), the following conversion values are exemplified: X = 0.619 R +0.177 G +0.204 B Y =0.299 R +0.586 G +0.115 B Z =0.000 R +0.056 G +0.944 B x = X /( X + Y + Z ) y = Y /( X + Y + Z )

Measuring the color of the plurality of light-emitting elements (11A, 11B, 11C, 11D, 11E, 11F, 11G) which are like the sun and the setting sun, R = 255, G = 255, B = 57, corresponding to the CIE chromaticity coordinates ( The trajectory point is calculated as follows: R = 255, X = 214.608; G = 255, Y = 232.23; B = 57, Z = 68.088; x = 0.416774449; y = 0.450996842; measure the color of the sunset light 1 minute before going down the mountain R = 235, G = 200, B = 35, and the corresponding CIE chromaticity coordinates are calculated as follows: R = 235, X = 188.005; G = 200, Y = 191.49; B = 35, Z = 44.24; x = 0.443685 ; y = 0.45191; measure the sunset light color R = 255, G = 239, B = 74 before the downhill, and the corresponding CIE chromaticity coordinates are calculated as follows: R = 255, X = 215.244; G = 239, Y =224.809; B = 74, Z = 83.24; x = 0.411326; y =0.429604.

The foregoing is an example of the conversion of the RGB and CIE chromaticity coordinates of the image (the rest and so on, and will not be described).

By this conversion process, the ( x , y ) (or ( x ', y ')) values of the CIE chromaticity diagram coordinates can be obtained, and one point can be marked, and the 60 images can be converted into X*Y planes in the CIE coordinates. 60 points above, forming a curve, as shown in Figure 6E, P _i = ( xp _i , yp _i ) is a specific time and space CIE data 31A (real sun and sunset, that is, the specific time of the present invention And the situational process of the location) at the i-th time point in the CIE chromaticity diagram of the trajectory. Q _i =( xq _i , yq _i ) is the trajectory point of a certain group of illuminating devices 11 in the CIE chromaticity diagram at the i-th time point. then , The distance to the point.

Any combination of the plurality of light-emitting elements (11A, 11B, 11C, 11D, 11E, 11F, 11G) defines a point-by-point accumulation of the j-th light-emitting elements (11A, 11B, 11C, 11D, 11E, 11F, 11G) The error Δ _{1 j is} as follows:

For example, referring to FIG. 6A, assuming that the track point Q _{11 is taken} as an example, the distance between the track point P _i and the track point P _i is calculated by the formula to be D1. Similarly, referring to the sixth B diagram, the distance between the track point Q ₁₂ and the track point P _i is D2. Further, as shown in the sixth C diagram, the distance between the track point Q ₁₃ and the track point P _i is D3. And so on, as shown in the sixth D picture (to avoid the surface disorder, the distance between the track points is omitted, not shown, combined with the first.).

When the time interval of the mood illumination color conversion is converted according to the original actual sun and sunset colors, the point-by-point cumulative error of the combination of the light-emitting elements is the best design, that is, Δ _opt =min[Δ ₁₁ , Δ ₁₂ , Δ Δ _{1 j} ]; (Refer to the sixth D diagram, assuming that the tracking points of Q ₁₁ , Q ₁₂ , Q ₁₃ , Q ₁₄ , Q ₁₅ , Q ₁₆ , Q ₁₇ , Q _i are taken as an example, The combined light emitted by the light-emitting element corresponding to Q _i is most in line with the ambient lighting color standard); Δ _opt is the error amount of the ambient lighting color change and the actual sun (or sunset) color change in the optimal design.

The invention can have at least the following two modes of execution:

[a] Instant comparison mode: taking a specific time and space 1 as an example, the processing device 40 retrieves the corresponding space-time CIE data 31A, activates the complex array light-emitting device 11, and changes each time point according to the situation change process. Corresponding to each track point ( x , y ) of the CIE chromaticity diagram, the instantaneous calculation of the RGB values of each combined ray corresponds to a plurality of track points ( x ', y ') of the CIE chromaticity diagram, and obtains The point-by-point cumulative error between the track points ( x , y ) is the minimum distance of the track point ( x ', y '), and the corresponding light-emitting element combination is re-lighted (refer to Figure 7A, assuming that the light-emitting elements 11A and 11B are turned on) ). By analogy, the illuminating element combination is as shown in the seventh B (assuming that the illuminating elements 11B and 11C are turned on), and the final illuminating element is combined as shown in the seventh C (assuming that the illuminating element 11G is turned on). The part to be explained here is that the processing device 40 has an extremely fast operation speed and only has two axes ( x ', y ') at a time, so that an immediate operation comparison can be performed.

[b] Pre-comparison mode: pre-establishing the corresponding combined light CIE data 31B of the plurality of pens according to the foregoing comparison process, using the specific time-space CIE data 31A of the plurality of pens (for example, the light-emitting component combination data of Table 2, In the application example, the light-emitting elements can be eight), and the time is divided into eight segments of t1, t2, t3, t4, t5, t6, t7, and t8, and the light-emitting element that lights up the code 0 first at t1 is only bright at t2. The combination of the light-emitting elements of codes 1 and 2 is referred to the description of Table 2, and finally, at t8, only the light-emitting element of code 7 is illuminated.

Similarly, the specific spatio-temporal data 31 corresponding to the specific time and space 2 "the sunset of the Yellow River (Lanzhou City) in the autumn of 2011 (the second embodiment)) may also be converted into the specific time and space CIE data 31A in advance, and The combination of the light-emitting elements of the present case is sequentially illuminated to achieve a color change that simulates the actual sunset. As shown in Table 3 below, the time is also divided into 8 segments of t1, t2, t3, t4, t5, t6, t7, and t8. The light-emitting component with the code 0 is first illuminated at t1, and the code 1 is illuminated at t2. For the combination of the light-emitting elements of 2, 3, the combination of the light-emitting elements of the codes 2, 3 and 4 is simultaneously illuminated at t3, and the rest is referred to the description of Table 3, and finally, at t8, only the light-emitting element of code 7 is illuminated.

The timing of the first number can be 8 timings within 10 minutes, or the length of the increase or decrease can be modified.

Regarding the third embodiment of the present invention, the plurality of light-emitting elements in the hardware aspect are still eight, as shown in Table 3. Thereafter, the input condition is changed: the first option value 21 is "no input"; the second option value 22 is "sunset mode"; and the third option value 23 is selected as "local cloud mode".

Then, the combination of the light-emitting elements can be defined as: first turning off the light-emitting element (11G) that emits infrared light, then starting the light-emitting element (11A and 11B) that emits red light, and emitting the light-emitting elements (11E and 11F) that emit yellow, causing the red light to slowly change. The dark and yellow light gradually becomes stronger, and then the light-emitting elements (11C and 11D) that emit white light are activated.

The "local cloud mode" is visually obscured as part of the central area P1. In fact, the representative will be covered (the hidden range is built-in, but dozens of modes can be built in, and the device can read randomly, and can get unpredictable novelty.) The central area P1 (see The light-emitting element of the oblique line portion of the eighth or eighth B diagram may be halved (or reduced to 1/4 or even completely reduced to zero) by the brightness of the light-emitting element. As shown in the fifth figure, each of the light-emitting elements is a variable resistor 112 (an auxiliary resistor 113 may be further added to assist in fine-tuning the light-emitting amplitude of the light-emitting element, and any device that can change the light-emitting element is not The range of protection from the present case) controls the brightness of the light, and the plurality of variable resistors 112 are controlled by the processing device 40.

That is, when the local cloud mode is used, the brightness of the plurality of light-emitting elements located in a part of the central area P1 is weakened, and the simulation can generate a cloud-like layer that blocks the sunset, the sun, and the moon. effect.

In addition, with regard to the moon mode, the spectrum of the moon can be regarded as black body radiation of 5000 degrees K, as a result of reflecting a sun light by a round stone, showing a pale yellow or yellow light due to the influence of the cloud layer. Moreover, when imitating the change of the moon's roundness, the brightness of some of the light-emitting elements is also weakened or extinguished, which can cause the visual effect of the moon's roundness change.

In summary, the advantages and effects of the present invention can be summarized as follows:

[1] simulates the luminescent color closest to the situation mode. When selecting any specific spatio-temporal data, the creation can capture each trajectory point ( x , y ) of the CIE chromaticity diagram at each time point of the context change process, and find out the corresponding RGB values of each combined ray. On the CIE chromaticity diagram, the point-by-point cumulative error between the trajectory points ( x , y ) is the minimum distance trajectory point ( x ', y '), and then re-illuminated with the trajectory point ( x ', y ') Corresponding to the combination of the illuminating elements, the combined ray emitted is the illuminating color closest to the situation mode. Therefore, the illuminating color closest to the situation mode can be simulated.

[2] has multiple display modes. This creation can calculate the coordinate value of the CIE graph with the minimum point-by-point cumulative error as the minimum distance by the RGB value of each combined light, which is the instant comparison mode. It is also possible to pre-establish the corresponding combined light CIE data of the plurality of pens by the data obtained by the instant comparison mode, which is a pre-comparison mode, and can be freely selected according to the setting. Therefore, there are multiple display modes.

[3] can simulate the situation of sunrise, sunset or moon in a specific time and space. In addition to simulating the general sunrise and sunset, the case can also be selected from the context of sunrise, sunset or moon at a specific date and location, such as the "Sunrise of the Alps on January 1, 2011". Make the case more selective.

[4] It is more realistic to have a local cloud mode. In the process of actual sunrise, sunset or moon light, there is often cloud interference, and this case also has a unique local cloud mode for more realistic simulation.

The present invention has been described in detail with reference to the preferred embodiments of the present invention, without departing from the spirit and scope of the invention.
