Description

Detailed Description of the Invention

  The present invention uses a smartphone and a tablet terminal (hereinafter referred to as a tablet) that enables color mixing, colorimetry, colorimetry, color analysis, and color vision determination from light color determination through CMY subtractive color mixing method and CIE XYZ colorimetric method. Involved in unprecedented CIE CMY-based integrated color standard system.

Today's representative color systems include Munsell color system and CIE color system (XYZ system, etc.), but neither of them is basically a concept of color size and there is no scale that can be added or subtracted. It is not compatible, and it is not possible to simply add and subtract colors to mix colors and measure and adjust colors. The light source color determination requires a separate color meter, and color vision determination is not targeted.
1) In other words, the Munsell color system problem is
(1) The color standard is limited to “reflective color” (reflective color) in the object color, and does not correspond to the “light source color” and “transparent color” that exist innumerably. Can not.
{Circle around (2)} The color space is narrow and lacks high-saturation colors, and the color charts are rough, and many colors cannot be completely equal. Most of them can only be guessed, and exact colorimetric values such as xy cannot be detected.

(3) In the era of the three primary colors, it does not correspond to the three primary colors, and CMY and RGB components, ratios, accurate xy and Lab are unknown, and color analysis and color addition and subtraction cannot be performed. If you mix a certain color with a certain color, you don't even know what color it will be.
(4) Color cannot be corrected or adjusted because color cannot be added or subtracted.
▲ 5 ▼ "Complementary color" is only known on the opposite side of the color wheel,
(8) The object color cannot cope with the problem that the color slightly and greatly changes depending on the illumination light source, and cannot be predicted.
(8) It is not easy to verify and verify whether the colorimetric values are correct.
(9) It is expensive, cannot be easily carried, has poor operability, and is not a color monolith that allows everyone to measure colors easily and precisely.

2) On the other hand, although the CIE colorimetric method is capable of strict colorimetry and colorimetry corresponding to the three primary colors, an expensive spectral colorimeter is indispensable for the colorimetry, and the CIE XYZ, xy, and HVC numerical values are known. However, even if a numerical value is shown, the color cannot be seen with the eyes, and it is not easy to verify and verify whether the measured value is correct. The CMY color mixing method of today's printing color reproduction method does not correspond to this at all, and addition and subtraction of colors cannot be performed, so it is not useful for solving the color mixing problem and the color correction problem.
Therefore, at present, it is difficult to understand the CIE color system itself. In other words, until now, it is difficult to understand because there is no system that can be connected to vision. Eventually, the light source color and the transmitted color can be handled while looking at the color with eyes, and the color is analyzed and colorimetrically measured and measured. This means that there is a lack of new color monosashi linked to the CMY method, which can also be adjusted. So, until now, all of “color” can only be seen in pieces, and it can be said that it is inevitable that the state of knowledge is extremely poor.

  Therefore, the same applicant pays attention to the CMY filter of the subtractive three primary colors, and the color system based on the subtractive color mixing method is “New color system using CC filter” (reference: Photo industry / July issue / 1975. New edition photo technology handbook ( Adopted as a color handling method using CC filters / P.41 / David), and then developed a computer color system (Japanese Patent No. 3225297), and the above problem as a CMY mixed color system that corresponds to the three primary colors and includes transmitted colors The point was radically reformed and the color art was greatly evolved and developed.

Problems to be solved by the invention

  However, this method, like the JIS standard color chart, requires an expensive CMY color scale, which is expensive to achieve the purpose. Color mixing and color measurement operations are time consuming and not easy, and are easily damaged. The visual color changes depending on the order, number of sheets, and multiple reflections, and it is very difficult to easily match the calculated value with the filter overlap color, standard color, and monitor color, and the "light source color" problem is similar to the Munsell color system. Due to the harmful spectral absorption that the filter cannot solve, a high saturation color cannot be obtained, and an expensive CMY scale must be carried around, which makes it difficult to use.

Means for solving the problem

  Therefore, the present invention comprehensively covers all “colors”, that is, light source color determination, color mixing problem, and color vision determination, and is a rigorous and multifunctional comprehensive color that anyone can solve inexpensively, easily, quickly and strictly. In order to achieve the purpose of the development of the system, the present invention controls the RGB monitor color development of the tablet terminal by the CIE color system and the CMY method, so that color mixing including free high-saturation colors can be performed by <CIE. Digital color standard> Obtaining color solves the fundamental problem.

  In other words, the monitor color obtained by the CIE color system and the CMY color mixing method on a tablet terminal enables infinite color mixing that can handle almost innumerable light source colors and transmitted colors, and the spectral distribution incorporated in the calculation is In addition to the actual filter value, by introducing an ideal, virtual CMY spectral distribution that does not exist in the real world as a primary color, it is possible to perform color mixing and colorimetry in a wide color space without the harmful effects of the actual color material. Yes.

In the present invention, (1) various actual CMY filters and achromatic ND filters are used as primary colors of subtractive color mixture for performing color calculation in tablet terminals (smartphones, portable personal computers, etc.) such as ipads and iphones used all over the world. (2) using two spectral calculation modes (Virtual mode), and (2) using various virtual spectral distributions such as ideal and virtual CMY and achromatic ND that are not in reality (Virtual mode). Any combination of density obtained in each, (3) by transmission color, reflection color,
(4) Color calculation (XYZ, xy, Lab, and Munsell HVC) is performed for each of the standard light sources A, B, C, D50, D55, D65, and F8, and the same color as the calculated value is displayed on the monitor screen <CIE digital Color standard>
(5) The developed color of the <digital color standard>, the reflection type and the transmission type color to be measured, and the visual color measurement value are obtained by the same color.
(6) The color quality of the light source, the color temperature, and the type of fluorescent lamp (D, N, W, WW, etc.) are calculated from the xy value of the <digital color standard> that is the same color as the reflective achromatic gray scale plate.

Effect of the invention

The present invention solves all the color problems related to color, which cannot be solved by any conventional color system, such as subtractive color mixing, color adjustment problems, light source color problems, and color vision problems. Systematic color calculation and <digital color standard> based on tablet color development enable fundamental solutions.
(Innovative features as a color system)
In the present invention, CMY values are obtained by CMY actual mode or virtual-virtual mode of CMY color system, and this is obtained by color calculation of CIE color system by XYZ, x, y. The Munsell HVC value is obtained from the L ^* a ^* b ^* value and the XYZ value, and a color equal to the calculated value is developed on the monitor. In the (Virtual) mode, the color is innumerable in a wide color space including a high chroma color. It is the birth of a new color system of a completely new dream that makes it easy, cheap and rigorous to mix colors and measure light source colors. As a result, defects that were in the conventional color system are completely covered, and the colors are made quantitatively in both name and reality. This is the first proof of color verification possible. This means that it was only possible to grasp the “essence of color” that had been impossible to know until now, and it became possible quickly and easily.

In other words, the present invention eliminates the need for expensive JIS standard color charts and CMY <color scales> by simply downloading the <CIE digital color standard> implementation application according to the present invention, and enabling countless transparent colors by operating the filter buttons on the terminal. Can be made with three colors of CMY, and is switched for each standard light source (A, B, C, D50, 55, 65, etc.) and displayed as <CIE digital color standard>, which is the standard <CIE digital color Standard> and the color to be measured are adjacent to each other so that they are the same color, and without the help of other spectrophotometers, etc., <CMY + ND value, CIE color system XYZ, x, y, L ^* a ^* b ^* , and Munsell The system's HVC numerical value> is displayed together with <spectral curve, chromaticity diagram> and all of its color characteristics are displayed. Furthermore, another method using a block-type virtual distribution (see FIG. 8) (Vir The color space can be expanded by the (ual) mode, and the effects that can be easily used all over the world as an unprecedented total color system, ranging from light source color to mixed color measurement in high-saturation color areas, color vision, It will be possible to bring about a revolutionary development in color handling.

(High saturation color, expansion of color space, (Virtual) mode)
The subtractive CMY colors inherently absorb only one of RGB as an absorber of the three primary colors RGB light, C is -B, M is -G, C is -R, and C + M = B, C + Y = G, G, Y + M = Innumerable transmitted colors (T) can be added or subtracted due to the relationship of R, and the calculated values can be created (colored) on the monitor. The reflected color (R) is reflected by the color calculation method when a white base is used under the filter. Color CIE values (CIEXYZ, x, y, L ^* a ^* b ^* in addition to the HVC value and color display can be obtained at the monitor color development part. The (Actual) mode using filters is a color mixture that matches the color material. Can measure colors.
However, all the actual CMY filters have a density distribution as shown in FIG. 8, and in addition to the ideal BGR absorption, C includes G light and R light in addition to R light, and M also includes R, Since there is harmful spectral absorption that slightly absorbs B light, for example, the combination of M and Y does not become pure R, but R is distorted in orange, and the combination of C and Y is particularly distorted by harmful spectral absorption of C. As a result, bright green is not obtained. In addition, a complete achromatic color cannot be achieved with a combination of three CMY colors.

  Therefore, in the actual (Actual) mode using a filter, the mixed colors are all distorted and high saturation colors cannot be obtained and cannot be measured, and there is a fatal problem in subtractive color mixing that the color space to be handled is narrow. In the virtual block spectral distribution (virtual) mode of the invention, each CMY color used is the block spectral distribution without harmful spectral absorption shown in FIG. 8 and various distributions in which the shapes of the blocks overlap each other in a mountain shape. Various color calculations can be freely performed, and almost innumerable <digital color standards> can be calculated and colored on the monitor, which makes it possible to completely solve the above-mentioned problems of high saturation color and color space.

(A myriad of colors)
Therefore, the (Actual) mode of the present invention corresponds to the filters used by each manufacturer, such as Actual-E and Actual-F for each of E company, F company, and L company, and according to the primary colors for each ink or paint. Color handling becomes possible.
Also, in the (Virtual) mode of the present invention, the color space is expanded to include high-saturation colors that cannot be obtained by conventional subtraction, and the color development stage is a barely detectable stage such as a density of 0.0175. As a result, stepless color change and ND density can be adjusted steplessly, so nearly infinite subtractive color calculation close to 16.7 million colors for monitor coloration can be made freely and accurate and precise. The effect of color mixing and colorimetry is not as great.

(Color recording and display, reproduction, operability)
The colorimetric measurement is performed in the same manner as the <CIE digital color standard> obtained as described above, and a vivid CIE value and color development that cannot be obtained with the standard color chart are obtained. The transmitted color by the C light source is 20c + 30m + 50y / T. / C, A light source reflection color is 30m + 50y / R / A, such as transmission (T), reflection (R) and different light sources, it is possible to display highly accurate, and monitor screen recording by button operation of screenshot It can be stored and reproduced freely, and it can have a data storage and reproduction function that was not available at all in conventional systems. It becomes quick and easy as compared to functionality and operability.

(Color analysis, complementary color)
The CMY values indicate the subtractive three primary color amounts as they are, and the three primary color ratios of the colors are found. Since the numerical values are densities (common logarithmic values of transmission and reflectance), color addition and subtraction can be freely performed, and color correction values (CMY amount differences) Complementary colors can also be calculated easily and accurately.
In other words, since the complementary color (opposite color) is the remaining amount subtracted from the equal CMY value, for example, 30c + 30m in the case of 30y, and 10m + 20y in the case of 50c + 40m + 30y can be verified. In the present invention, it is possible to easily and visually obtain a color verification that is free of distortion and bias of an ideal color in terms of calculated values and color development.

(Verification of calculated values and color development)
To verify whether the calculated value and color development are correct, in the case of transmission color, if CMY with clear transmittance is located next to the color development part of the colorimetric window or if an ND filter is positioned, the standard observation will be performed. If it is a person's color vision, both will match equally visually and numerically. In other words, the calculated value on the tablet appears to be the same color as the actual filter and the numerical value obtained by the photoelectric colorimeter (or the numerical value in the filter manufacturer's characteristic manual).
The problem of subtle color development characteristics of monitor color development that differs depending on the product can be finely adjusted according to the monitor characteristics on the application side. In addition, since this invention has already achieved it at this time, it is also possible to submit evidence.

(Reflective color)
As for the reflection color, ND color is displayed by various ND filter buttons as a calibration method, the light source button is switched to the reflection (R) button, and the ND color chart of the same ND value and the monitor color under the standard light source are colorimetric. However, it is only necessary to adjust the brightness of both to be equal by “brightness setting” provided in the main body, and if all the conditions are satisfied, the verification data of the present invention is approximated in many cases as shown in FIG. It can be seen that the color of both reflected colors shows an approximate value by the actual filter color scale or more. The reason for this is that the calculated color can be obtained without the problems described in 1) at the beginning (harmful spectral absorption of the actual filter, multiple reflections between the surfaces, adverse effects due to the overlapping order), and the pigment is the first pigment in a wide color space. It is now possible to create a revolutionary new <CIE digital color standard> colorimetric method that is possible with mobile devices without the use of color materials. As with the metric system, you can freely add and subtract colors, perform precise color measurement, and freely adjust and adjust colors.

(Verification and verification)
In the conventional method, it is difficult to verify the color. The color chart needs to be measured with a photoelectric colorimeter, and there are many cases where it is not known whether the data obtained by the photoelectric colorimeter is accurate. However, according to the present invention, a filter or standard color is adjacent as a transmitted color, and the CIE numerical value of both of them and the comparison verification of the colors make it clear whether the <CIE digital color standard> is correct or not.
This means that the present invention can verify and verify whether the color charts and the measured values by the photoelectric colorimeter are correct, and how the color changes depending on the illumination light source, greatly reforming the world of practical color handling. It becomes possible.
In addition, in the present invention, it is possible to calculate both colors using an actual filter color and an ideal virtual spectral distribution. In either case, FIG. 9 (filter manufacturer's catalog value, tablet spectral distribution using a tablet) Comparing the calculated value by the virtual block method and the calculated value by the virtual block method) Even if the color spectral distributions are different, the colors match if the CIE numerical values match, and the CIE numerical values match if the colors match. However, the effects that can be demonstrated in countless examples would be typical examples that impact many people.

(Portability, operability)
Portability and operability are dramatically improved. In the conventional spot filter scale method, it is very troublesome to put in and out a large number of filter pieces, and color creation that takes tens of seconds and minutes to equal colors can be instantaneously performed with a button operation in the present invention. -Color matching operations can be performed at a speed that is not comparable to conventional methods.

(Comprehensive understanding of color)
All colors are shown with CIE values and monitor color, and spectral curves and chromaticity diagrams. Therefore, the color is concretely <color development, numerical value, curve, and graph>, and the entire image of the color is sufficiently shown, and the understanding of the entire image of the color can be learned for the first time.
In addition, in the present invention, as an option, when a spectral distribution value from 400 nm to 700 nm is input, an XYZ colorimetric calculation value and a CIE color calculation menu that enables monitor color development are prepared. Various color calculation programming can be incorporated by obtaining the representative color from the color name by searching, and further obtaining the correct color by inputting xyY, Lab, and HVC values, specifically by <color development, numerical value, curve and graph>. This makes it possible to understand and learn color practices and colors that were not possible before. This is because various functions of an unprecedented CIE visual comprehensive color system that can be said to have been understood for the first time are provided.

At the same time, the demonstrative nature of the present invention, which can answer the question of “why it is” that is almost impossible with other color systems, has a great effect on enlightenment of the subtractive color mixing method that has been delayed in color.
In particular, subtractive color mixing is a problem that is not well understood by color specialists because it cannot be easily logically solved by methods such as paint other than the filter calculation method. Therefore, even the prestigious and expensive color book was a super challenge that the explanation was missing, but according to the present invention, the numerical value and coloring, curves and graphs make it easy and strictly logical, A clear solution is possible scientifically and empirically. Its functions that make it easy and quick to understand and convince with the mobile devices that everyone always wears are truly worthy of being called the IT revolution in colours and colours.

Further, in the present invention, as with other visual color determination methods, the coloration and color matching between the monitor color development and the in-situ filter and the JIS standard color chart are based on the difference in the color vision characteristics of the eye that is the light receiver. The problem arises that the color values are different. However, this is not a drawback in the present invention. There is an advantage that can be used for verification and verification of color vision color characteristics that could not be achieved by the conventional method. In other words, in the present invention, numerical values and colors are indicated by calculated values by the CIE color matching function of the CIE colorimetric method. Therefore, colors match when the observer's color sense is the same as that of the CIE standard observer. However, if the observer's color sense is different from the CIE color matching function, the color sense of each eye The difference in characteristics can be verified empirically.
By the way, the difference in the colorimetric color values when the XYZ, xy, and Lab have clear achromatic or chromatic color charts as the standard of judgment and the color is strictly equalized with a standard light source, the CIE standard observation of the observer as it is As a difference in color characteristics from the user, according to the Lab method, it is possible to find out how much difference is in which color direction. This is because, for example, in the case of an achromatic color, even if the color chart is flat, the monitor coloration that is the same color is an RGB color mixture, so if the eye color matching function is different from the standard value, the XYZ values will be different, etc. This is because the color disappears.
Therefore, the color vision determination function of the present invention can be greatly used for elucidation of unknown parts of color vision science, which is also a very great effect brought about by the invention.
As the color vision related literatures of the same applicant to date, Japanese Patent Application 2002-307660, Japanese Patent Application 2002-313509, Japanese Patent Application 2002-272285, Japanese Patent Application 2005-154469, Japanese Patent Application 2006-134490, Japanese Patent Application 2007-125015, and the like. is there.

  As described above, the present invention is a light source color problem that has not been clearly solved so far, an unsolved problem elucidation from subtractive color mixing problem to color vision problem, and color and actual color practice, It will be possible to make great use of the color knowledge that has been delayed and the dramatic improvement and improvement of color education.

FIG. 1 shows an example in which a tablet terminal similar to a smartphone such as iPhone is turned on and the <CIE digital color standard> system of the present invention is called up on the screen.
The monitor screen 2 of the main body 1 is roughly divided into a colorimetric window part, a filter button part, a transmission / reflection switching part, and a light source switching part. One of the colorimetric windows 3 has a monitor color developing part and an equivalent RGB 256 in contact therewith. There is a white space (white) part. Then, the CIE color calculation result calculated from the spectral transmittance of each of the filters singly or in combination by the filter button operation is displayed on the numerical value display unit 6, and the calculated correct color is displayed on the coloring unit 4. Then, the button 9 switches between transmission and reflection, and the light source switching button 10 displays numerical values and colors corresponding to various light sources. Various buttons are structured so that the brightness of the buttons is reversed when pressed, and disappears with numerical values and color displays when pressed again, and all are reset to the initial state by the clear button.

FIG. 2 is an explanatory diagram illustrating a measurement state in which the 30C filter is displayed in the white space, while the 30C filter is displayed as a transmission color (T) by pressing the 30C button. The numerical display unit 6 shows the color characteristics of the CIE color system of the 30C filter, and is adjusted so that the correct color having the numerical value of the 30C filter is developed in the color forming unit 4.
Therefore, if the actual 30C filter is located in the white space and the colors 4 and 5 are color-matched as shown in the figure, the colors are equalized in the CIE standard observer in an appropriate state.

Although a Kodak CC filter is used here, the calculated value approximates the catalog display value, and the color development also substantially matches. This proves that accurate calculation, color display, and color measurement are possible. This is the same when other combinations of CMY and ND buttons are used, and it is particularly surprising in the case of transparent colors even when many buttons are pressed (when many filters are stacked) in an appropriate monitor state. Approximate color matching.
This means that the transmitted color is the lightest 025 levels, and a large number of almost transparent colors can be displayed and mixed correctly. This enables an unprecedented revolutionary color measurement that can be measured easily and reliably. This is a serious event. There has never been a transparent color visual standard in the world. It would be hard to believe even an expert that it can be obtained easily and cheaply with a terminal without a real filter.
In addition, according to CMY calculation and color development using an ideal block-type virtual spectral distribution with no harmful spectral absorption, color handling far beyond the conventional subtractive color mixture range and could not be performed in a wide color space close to RGB color mixture. It becomes possible.

FIG. 3 shows an example of the measurement state of the reflected color by the C light source. When the light source switching button 10 is switched to reflection (R), in principle, a color calculation result similar to that obtained when the 30C filter is brought into close contact with the white surface and light passes through the filter twice is displayed on the numerical value display unit 6. The calculated color is developed on the coloring section 4.
As for the reflected color, the Munsell HVC value is displayed in the C light source, D65 or the like. HVC in the case of 30 C / R with C light source is (H5.0B V8.0 / C5.4), and there is no 5 in the JIS standard color chart, but it should be in a position 1.4 higher than C4 there Is colored. In other words, in this <CIE digital color standard>, the high saturation color that is not in the JIS standard color chart and the intermediate numerical value that is not in the color chart and its color can be said to be infinite in 025 units or 0175 units. A large number of colorimetric measurements are possible.
In addition, spectral curves, chromaticity diagrams, color search from various numerical values or color names, color encyclopedia functions, etc., which were difficult with the conventional method, can be performed by button operation, sending the screen to the next page, or using the spread function of the terminal. It is possible to enhance the color system functions as a more versatile and comprehensive <CIE digital color standard> system.

  FIG. 4 is an explanatory diagram in the case of using a colorimetric mask 16 having a colorimetric window 17 in order to perform accurate colorimetric / colorimetric operations in colorimetric / colorimetric operations. In this case, if adjusted strictly, a standard observer will see the same color so that the digital color in one of the two colorimetric windows and the measured color in the other cannot be distinguished.

  FIG. 5 is an explanatory side view showing a colorimetric and color matching operation state when an illumination light source having the same color quality as that of various standard light sources is provided on the back of the terminal to enable color measurement of the reflected color. When the illumination light source unit 18 is opened, the same CIE color system A, B, C, D50, 55, 65 as the operation light source emits standard light so that the measured color unit can be illuminated, and thereby the specified light source is used. It enables ideal and accurate colorimetry and colorimetry of reflected colors, and can be completed as a visual colorimeter. The illumination light source can be easily produced as a monitor color, and can be emitted by one spread-type monitor or supplied as an adapter.

  FIG. 6 shows an example of a large tablet such as iPad. In this case, the chromaticity diagram 17 obtained from x and y is displayed on the screen simultaneously with the spectral curve 16 of each color, so that for each color, the reflected color (T) is the spectral transmittance and the reflected color (R) is the spectral spectrum. As a reflectance, the position on the chromaticity diagram is determined. By observing the continuous change of the spectral curve and chromaticity point by operating each filter, transmission / reflection, and light source button, each unknown color characteristic can be understood in a very easy-to-understand manner.

Further, in the present invention, by opening the option button 18, for example, if a spectral transmittance and a spectral reflectance are input, a calculation menu for obtaining a monitor color can be obtained as a result of CIE calculation. By searching for and displaying the color from any color name or any HVC value, functions such as the conventional color encyclopedia and color encyclopedia can be made possible, and it can be expanded and enhanced as a more versatile color system. Become.
With this configuration, the present invention makes it possible to grasp all the colors, the numerical values and the color development of the monitor, and the whole image of the colors shown in the spectral curve and the chromaticity diagram. Anyone can clearly understand the colors, and if they are used in color education, they can be used greatly in a wide range of areas such as color and knowledge, improved color practice, improved color sensation, and color vision judgment. Become.

FIG. 7 shows the CMY and ND (achromatic) colors of the present invention, the ideal spectral distribution (only 25, 27, and 29 in FIG. 8) of the virtual block type without harmful spectral absorption as primary colors (color calculation basic colors). This is an embodiment in which free color mixing is made possible by changing this stepwise or continuously.
In the present invention, by operating each of the up / down keys 23, CMYN can be mixed in a stepless and continuous manner, and subtractive color mixing can be performed quickly and freely. It is comprised so that. In this case, a part of the spectral distribution diagram is not a curve but similar to FIG.
The actual normal CMY filter has harmful spectral absorption shown in gray in FIG. 8, which is polymerized to cause color distortion, but it is possible to achieve an ideal color mixture without any harmful effects, and the lightness can be ND density. Again, by changing stepwise and continuously, almost infinite color mixing including high-saturation color and visual colorimetry are possible, which is not possible with the spectral calculation of the filter.

FIG. 8 is an explanatory diagram of harmful spectral absorption of an actual CMY filter. The harmful spectral absorption refers to not only the intended RGB light (C is -R, M is -G, and Y is -B), but also other undesirable absorption. Here, the harmful spectral absorption portions (26, 28, 30) are shown in gray as a block as an average value of spectral transmittances of three 50CMY filters of an actual CC filter.
In other words, the target absorption range of each of the three filters of 50 CMY is 25 light for C dye, G light for 27 M dye, and 29 light for Y dye. In addition, the C dye is 26, the M dye is 28, and the Y dye is 30, which is an undesirable harmful spectral absorption. Therefore, the color is distorted and the vividness is lowered, and a high saturation color cannot be produced. In the subtractive color mixture, the color space region is significantly limited on the chromaticity diagram as compared with the factual additive color mixture.

For this reason, the conventional CMY filter method has a defect that the degree of correspondence to a high saturation color is low. However, in the present invention, the above problem is solved by creating and using the above-described virtual mode without harmful spectral absorption. It can be solved entirely. For example, 50CMY is calculated with 25, 27, and 29 pure color portions excluding the harmful absorption portions (26, 28, and 30) in FIG. 8, and a vivid color mixture is applied, so that a complete achromatic color is obtained at 25 + 27 + 29 portions.
FIG. 9 shows a calculation example of how accurate the color mixing result of the present invention is. Each of the verification values almost coincides with the filter catalog value, and the numerical value by the BlocK method and the color development are very close. If the values match, the visual color will match. And if the colors match, the numerical values also match. It is a proof of correctness and consistency as a color mixing method and a colorimetric method.

(Light source color judgment)
Conventionally, there are color charts for determining light colors using conditions and other colors, but XYZ, xy, and color temperature are unknown, and an expensive color thermometer (color meter) is required to know exact CIE colorimetric values. Was necessary.
However, according to the present invention, it is possible to obtain the CIE numerical value of the light source color strictly and inexpensively by the visual judgment.
The principle is explained with reference to FIG. 3. An achromatic gray scale stage is set at 15 positions, and the type of light source is selected so that the illumination light from the light source and the monitor color development of 4 are equal in brightness and color, and the ND button The color matching is performed by operating the CMY buttons.
In this way, when xy when the color is equal to the gray scale is read, it is the chromaticity of the light source. From the chromaticity, the color temperature of the light source ° K numerical value, and JIS "chromaticity range of light source color of fluorescent lamp" In addition, the type of fluorescent lamp (D, N, W, WW, etc.) can be detected.

In the artificial light source, the brightness of the grayscale reflected light varies depending on the distance from the light source, so that it is possible to perform color matching by appropriately adjusting the distance from the light source. Therefore, in a simple manner, a colorless reflector seal is provided at the position 5b in FIG.
In the present invention, the color characteristic changes depending on the color quality of the illuminating light source, and the change in color can be made numerical and visual by switching the light source button. This makes it possible to verify extremely strict color characteristics that could not be achieved.
That is, since the chromaticity xy indicates the position in the chromaticity diagram, the color characteristics deviating from the color temperature locus are found, so how much the same color temperature value is shifted in the G direction and the M direction, the mixed light source, etc. That is, it has a function of enabling determination of a light source color that does not correspond to the standard light source.
FIG. 10 is a side view of an embodiment of a colorimetric adapter device capable of performing the colorimetry easily and precisely. In this example, when the adapter device main body 33 is attached to the tablet 31, the color light 37 of the <digital color standard> of the color developing portion 32 of the tablet and the incident light (illumination light) 38 from the light receiving window at the top of the adapter main body are glass. As shown in FIG. 11, the colored light 37 and the illumination light 38 are juxtaposed to the eye cup colorimetric unit 5 through the fiber 36, and color matching is possible. It is possible.

(Color vision judgment)
The colorimetric adapter device can be used for strict determination in color vision determination. In other words, as long as the present invention is a visual perception determination method, the obtained xy value is merely personal observation data, and the value varies depending on the color matching function of the observer. Therefore, if a deviation from a CIE standard observer value, that is, a photoelectric color meter, or a majority judgment value, is found, the individual color of the film or camera as the color characteristic of the eye of the individual observer. Similar to the characteristics, it can be handled as individual color vision characteristics, and in the present invention, it is possible to solve a comprehensive color problem including the color vision problem in addition to the problem of the light source that could not be handled by the conventional color system.

  The present invention provides a high-precision CIE colorimetric method for tablets (multifunctional portable terminals) for all color-related problems from light source problems to color mixing, color measurement, color adjustment, and color vision problems in all fields related to color. In color calculation, CMY subtractive color values can be found as transmitted colors and reflected colors, and the addition and subtraction results are displayed on the monitor screen with the correct <CIE digital color standard> color corresponding to the calculated values, <Actual>, <Vertical> Can be displayed separately, by light source, by standard light source, can detect the xy and color temperature of the light source color, which was almost impossible with conventional color development systems, far beyond the Munsell color chart function, and also the basic software Special option modes, etc. can be supplied at a low cost by downloading from the net. For the first time in history, as a comprehensive color system with a common color calculation function, and CIE visual As digital color standard, the world's first comprehensive color system to be available across the border all industries and business around the world, to life in general.

(Practice, life)
In the present invention, not only the object color but also the light source characteristics can be used to make almost infinite color and the color judgment can be made, so it is always equivalent to carrying a color meter, photoelectric colorimeter, color calculation scale, color comprehensive dictionary, Strict handling is possible in all aspects of daily life from work.
In the color materials industry, high-saturation colors that could not be achieved at all, such as reflected colors and transmitted colors of products, reflected colors of light sources, and transmitted colors by strict calculation and monitor coloring in ink, dye, pigment, food, etc. Color options can be handled in a variety of modes using an option menu that allows you to input the spectral distribution of the primary colors.
Dye adjustment, color material adjustment, ink adjustment, and other color adjustments and corrections include specific correction values such as how many colors should be added and subtracted to obtain the desired color by adding and subtracting colors. As you can see, in industry, industrial products, as well as painting, design, printing, offset and color printing in inkjet printing, color mixing, color analysis, ink color addition and subtraction, selection of printing ink color on colored paper, Similarly, the simulation for predicting the color mixture of the paint or the dye can quickly obtain the desired adjustment value including the light source change with little trial and error. It is useful for strict color mixing, colorimetry, and toning in all fields that handle color.

Stained glass, colored glass, plastics, products, etc., such as the color of wine, coffee, juice, etc. Revolutionary, the world's first exact solution is possible.
In general life, you can see whether the color changes according to the choice of clothing and daily necessities, and the light source, and even though those colors can be taken with the camera, it is difficult to record correctly, and it is not possible to record colorimetrically However, in the present invention, many problems can be solved for object colors including light source colors and transmitted colors.

(Color science education, learning)
In the era of three primary colors, although the three primary colors, subtractive color mixing, and CIE color scheme are essential knowledge, color education is far behind. Because it lacks. In the present invention that can handle the CIE colorimetric method with visual sensation, color mixing results, transmission and reflection differences, light source differences, light source changes, and all color calculation results are shown in numerical values, color development, spectral curves and chromaticity diagrams. It becomes easy to understand, and it is possible to understand what the color is and the whole image including the light color according to the CIE colorimetric method.
In particular, the effect of being able to verify the difference between numerical values and color development while simultaneously comparing the difference in color space between the actual filter color and the color mixture by the virtual spectral distribution is a dramatic development in color science, and learning and learning of color science. It will greatly help to dramatically improve the level.

  Therefore, the CIE color scheme has been considered difficult at the university level, but the color simulation of button operation is accepted and accepted at the elementary school level. Therefore, color matching is possible in mathematics, science, art, and integrated classes. If you have a question about why the colors match, you can play the game, for example, show the target color and compete for who can quickly match the colors. It leads to strengthening of scientific power, color is sense, but CIE is mathematics, so it can be docked between the right and left brain in mathematics, and at the same time, it can be the best educational reform method in that it can develop the ability to ask questions and think . Because it uses the head with the senses, I think it would be ideal for science-based infant education.

(Color vision field)
As described above, in the present invention, there is a problem that the color sense of the observer does not match if the color sense of the observer is different from the CIE color matching function. Can be elucidated and can be greatly useful in the field of color vision science.
There has never been a color system that can cover a range of colors from color mixing to colorimetry, colorimetry, color calculation, color correction, subtractive color mixing, and color vision problems. This function can greatly contribute to the development, advancement and improvement of color science as a comprehensive digital color system.

(Reflective color)
That is, in the case of the transmission color, the verification data of the present invention is as shown in FIG. 9, and for the reflection color, the ND color is displayed by various ND filter buttons as the calibration method, and the light source button is switched to the reflection (R) button. An ND color chart having the same ND value under a standard light source (for example, an achromatic color chart having a reflection density of 0.2 (Y63.09) for a 10ND button (Y63.23)) and a monitor color are provided in the main body. It is only necessary to adjust the brightness so that they are equal to each other by “brightness setting”. If the monitor ND color approximates the reflectance of the standard ND color chart, for example, it approximates the highlight of a cigarette.
Monitor calculation value of <45C + 10M + 025Y / reflection / C light source> HV / C = 2.5PB / 5.3 / 6, Y = 22.08, x = 0.235, y = 0.250 (light source C) Catalog value of color chart 2.5PB / 5/6
Y = 19.27, x = 0.2365, y = 0.248 8 and xy show almost the same value, and the monitor color development can also be terribly consistent with the color chart of the Y3% difference. In this way, reflection colorimetric values can be obtained with extremely strict colorimetric accuracy that cannot be achieved with the actual filter color scale. Such evidence can be submitted for many cases.
In this way, the calculated color can be obtained without the problems described in the first 1) (hazardous spectral absorption of the actual filter, surface reflection, multiple reflections between them, and adverse effects due to the overlapping order), and the color is the first pigment in an unprecedented wide color space. , The birth of a revolutionary new <CIE digital color standard> colorimetric method that makes it possible to measure an enormous number of millions of colors with a mobile device without using coloring materials such as dyes Became possible.

FIG. 5 is an explanatory side view showing a colorimetric and color matching operation state when an illumination light source having the same color quality as that of various standard light sources is provided on the back of the terminal to enable color measurement of the reflected color. When the illumination light source unit 18 is opened, the same CIE color system A, B, C, D50, 55, 65 as the operation light source emits standard light so that the measured color unit can be illuminated, and thereby the specified light source is used. It enables ideal and accurate colorimetry and colorimetry of reflected colors, and can be completed as a visual colorimeter. The illumination light source can be easily produced as a monitor color, and can be emitted by the option button on the monitor screen or one of the spread-type monitors, or supplied as an adapter. And since it is a standard light source, it can also be used for illumination when observing the correct color.
