FIG. 3 shows a service image in the system of the present invention. The figure shows a service for purchasing flowers. The apparatus is largely divided into a center side (a seller side in a market or the like) and a client side (a remote purchaser side), and these are connected so that information can be exchanged using communication means.

[0029]

Embodiments of the present invention will be described below in detail with reference to the drawings. [First Embodiment] In the present embodiment, a description will be given of a case where flowers and flowers are to be sold and purchased. FIG. 4 shows the system configuration of the first embodiment of the present invention.

The center-side device 100 comprises a control unit 110, a colorimetric value calculation unit 150, a color number determination unit 160, and a data transmission unit 170.
01, image data input unit 102, spectral reflectance measurement unit 10
3. The spectral reflectance data input unit 104 is connected.
The client-side device 200 includes a data receiving unit 210 and a control unit 220, and the image display unit 201 is connected to the control unit 220.

FIG. 5 is a flowchart showing the operation of the first embodiment of the present invention. Step 101) First, the image photographing unit 101 of the center apparatus 100 photographs an image of a flower which is a product under the illumination light A, and inputs the photographed image from the image data input unit 102 to the computer. Step 102) Separately from step 101, the spectral distribution of petal colors (spectral reflectance: reflectance of light at each measurement wavelength) is measured using a spectral reflectance measuring unit 103 (spectral measuring device), and spectral reflectance data is obtained. The data is input from the input unit 104 to the colorimetric value calculation unit 150 and the color number determination unit 160. An existing spectrophotometer may be used as the spectrum measuring device, or a flash device, a plurality of bandpass filters,
Measurement can also be performed by combining a CD camera and photographing a plurality of times while changing the filter.

Step 103) Colorimetric value calculation section 150
Calculates the colorimetric value of the color of the flower using the measured spectral reflectance of the petals. Here, the colorimetric value is a quantification of the color appearance of an object, and is a CIE (International Commission on Illumination).
Is the most common. Further, by converting the XYZ display to a uniform color space L ^* a ^* b ^* space or L ^* u ^* v ^* space, it is possible to compare colors closer to the human interval. There are various other colorimetric value display methods, but here, the colorimetric value display method is not limited. For the calculation method of the colorimetric value from the spectral reflectance, refer to the reference (Noboru Ota, “Basics of Color Reproduction Engineering”, Corona, p.
p.8 (first line) to pp.12 (final line), and conversion to a uniform color space L ^* a ^* b ^* space or L ^* u ^* v ^* space, see the above-mentioned reference (pp.26). To pp. 29), etc., and are omitted here.

Step 104) Next, the color number judging section 1
In 60, using the spectral reflectance of the petals, a color chart generally used for registration of flower colors and the like (edited by the Ministry of Agriculture, Forestry and Fisheries, “Japan Horticultural Plant Standard Color Chart” (Japan Color Research Institute) (1995 is representative) is determined. The following two methods can be considered as a method of determining the corresponding color from the spectral reflectance.

(1) Data obtained by measuring the colorimetric values of all colors in the color chart are stored in a database, and the colorimetric values calculated for the measured petals are matched with the database, and the closest colorimetric value is determined. Select the color of the color chart you have. (2) Have the expert see the actual flower and determine the color number on the corresponding color chart. Then, the spectral reflectance of the petals is measured, and case data in which the spectral reflectance is associated with the color number of the color chart is accumulated.

Now, assuming that the total number of measurement wavelengths in the spectrum measurement is N, these integrated data can be regarded as a set of points of a case having a color number as attribute data in an N-dimensional space. Is considered to form a fixed cluster for each color number. Therefore, it is only necessary to determine which color number of the newly measured spectral reflectance data of the petal is close to the cluster of the case of the color number in the group of points of this case.

As a method for realizing such a determination,
Statistical methods such as discriminant analysis and methods using neural networks are conceivable. The statistical discrimination method is generally used in various other situations such as character recognition, and has various variations and various ideas. In particular, it has been shown that the color of a large number of flowers can be efficiently distinguished by using principal component analysis (Reference: "Spectral characteristics of flower color", Hitoshi Komatsubara, Color Research, Vol.44 No.2, 199
7, pp.15 to pp.18). Other general statistical discrimination methods are described in detail throughout the entire reference (Kenichiro Ishii et al., "Easy Pattern Recognition", Ohmsha).

When a neural network is used, the spectral reflectance of the integrated case data is used as input data (input to N units) of the three-layer neural network, and the color to which it belongs belongs to the error back propagation method as teacher data. By learning with, a function approximating the distribution of the case data in the N-dimensional space can be obtained. By inputting the newly measured spectral reflectance data of the petals to the learned neural network, it is possible to determine which color number the petal belongs to.

The discrimination by the neural network is described in a reference document (Yuichiro Anzai, "Iwanami Lecture on Software Science Recognition and Learning", Iwanami Shoten, pp.329-346). By using these methods, the color number of the corresponding color in the color chart can be determined from the spectral reflectance of the petals. Note that an expert who is skilled in viewing the color chart may compare the color chart with the actual flower to determine the color number of the corresponding color, and input the result to a computer.

Step 105) Then, in addition to the image data of the photographed flower, the data transmitting section 170 calculates the calorimetric value information of the calculated petals, the determined color number, and the attribute information on the flower such as the price and the place of production. The data is transferred to the computer on the client (purchaser) side 200 using communication means. Next, the client side 200 will be described.

Step 106) Client side 200
Are waiting in a state where they can receive data from the center side 200, and the data receiving unit 210 receives the data. Step 107) If the data reception is completed, proceed to step 108; otherwise, proceed to step 10
Then, the process goes to 6 to wait for reception.

Step 108) The received image data of the flower and the attribute information on the flower are displayed on the image display unit 201. With regard to the color number in the color chart in the transferred attribute information, if the actual color chart is prepared on the client side 200, the color can be intuitively understood. As for the data transmission / reception, a method of transferring data only when requested by the client 200 may be used.

When displaying an image of a flower on the client side 200, the display is performed so that the position of the petal whose spectral reflectance has been measured can be specified, which helps in determining the color quality. The purchaser judges the quality and price by looking at the displayed image and attribute information, and places a purchase order as necessary. The purchase order is input by the purchaser to the computer on the client side 200, and the input purchase order is transferred to the computer on the center side 100 by communication means and accepted.

[Second Embodiment] In this embodiment, the measured spectral reflectance of an object and the spectral reflectance and color grade of the object registered in advance for each type of object are defined. Determine the color grade of the object using the database that records the relationship,
An example will be described in which class information of the determined color is used as attribute data.

FIG. 6 shows a system configuration of a second embodiment of the present invention. The same components as those in FIG.
The description is omitted. In the center side 100 shown in the figure, a color grade determination unit 180 and a database 105 storing information relating to a spectral reflectance or a colorimetric value and a color grade are added to the configuration shown in FIG.

In the above-described first embodiment, the colorimetric value information of the petals, the color number, and the information such as the price and the place of production are used as the attribute data relating to the flowers. This is one of the attribute data items related to the flowers for which the class of is determined. FIG. 7 is a flowchart of the operation of the second embodiment of the present invention. In this embodiment, in step 203,
The color grade determination unit 180 refers to the database 105,
Determining the color grade of the object is an operation different from that of the first embodiment.

In general, agricultural products such as fruits and vegetables are classified according to their various properties (size, sweetness, etc.), and the grade information helps to determine quality and price.
Even in the case of flowers, it is possible to classify them by color, size, and the like. In the present invention, by transferring an image of a flower, much of information necessary for quality evaluation such as size information can be obtained from the image.

On the other hand, color information cannot be sufficiently conveyed by the image alone due to the limitations of the photographing device and the display device. In the first embodiment, the colorimetric value information of the petals, the color number, and the like are used. The information was used to help determine the quality. However, the quality of the petals may not always be easily determined based on only the colorimetric value information and the color number of the petals. Therefore, the quality of the color is evaluated and the grade of the color is determined, so that the quality of the color can be easily determined.

There are the following two methods for achieving color grading. (A) The price of a flower changes depending on the vividness and unusualness of the color. By accumulating data on the prices and shades (spectral reflectance of petals) of flowers that were actually shipped, and by taking into account other personnel (season, supply and demand balance at that time) that determine prices, and performing statistical processing, You can check the relationship between flower color and price. Using this result, the classification can be performed based on the color (spectral reflectance) of the flower.

(B) Having a flower expert look at the flowers actually received and subjectively judge the grade, a set of the grade information and the spectral reflectance data of the petal is accumulated. By applying the discrimination method as shown in the first embodiment, it is possible to classify the flowers based on the color tone (spectral reflectance). [Third Embodiment] In the above-described first embodiment, the image of a flower is simply photographed, transferred, and displayed. However, in the present embodiment, the influence of illumination at the time of photographing an image, and the effect of illumination in an image display environment. By displaying the influence and a color outside the display limit of the display device in a pseudo manner, an image display that looks natural can be realized.

FIG. 8 shows a system configuration according to the third embodiment of the present invention. In the configuration shown in the figure, the same components as those of FIG. 4 are denoted by the same reference numerals, and the description thereof will be omitted. The configuration shown in FIG. 8 is different from the configuration shown in FIG. 4 in that a color adjustment unit 114 for performing color adjustment on an image captured by the image capturing unit 101 is added on the center side 100 and a color conversion unit 230 and display device adjustment unit 2
02 is added.

FIG. 9 is a flowchart of the operation of the third embodiment of the present invention. 5 differs from the operation shown in FIG. 5 in that, in step 302, color adjustment of the image taken in step 301 is performed so as to remove the tint of illumination light, and the client 200
, The display device is adjusted according to the lighting conditions in step 307, and color conversion is performed in step 310 so that colors outside the color reproduction range can be displayed in a pseudo manner.

Humans can carry out stable color recognition unconsciously by excluding the influence of the lighting conditions of the environment in which they are placed (color constancy). However, when an image captured under a certain illumination is displayed in an environment with different illumination conditions, the color constancy does not hold, and a color resulting from a difference in the illumination conditions is added. When purchasing flowers, it is important to accurately determine the color of the flowers, and it is necessary to eliminate such color shifts. On the other hand, an image capturing device and a display device each have a limit on the colors that can be reproduced, and these are generally different. In particular, in the case of flowers, there are those with very bright colors, and display is often difficult. Therefore, it is necessary to simulate the colors of the captured colors that are outside the reproduction limit of the display device.

As a method of eliminating the color of the illumination light at the time of photographing, a white balance function provided in the photographing apparatus itself (automatically adjusts the color so that the saturation of the low chroma portion in the image approaches 0). To adjust). If the spectral characteristics of the illumination light are known, the tint of the illumination light can be eliminated by dividing the pixel value of the corresponding wavelength of the captured image by the spectral value of the illumination for each wavelength.

The spectral characteristics of the illumination light can be measured by using a radiation photometer. If the spectral characteristics of the light source of the illumination light are known in advance, the data can be used. In order to eliminate the influence of the lighting condition of the place where the display device (image display unit 201) of the client side 200 is placed, the color displayed on the display device under the lighting condition is adjusted to look natural. do it. Generally, commercially available computers and display devices (monitors) have a function for easily performing such color adjustment, and this function may be used.

In the color conversion section 230 of the client side 200, there is an existing method for pseudo-displaying a color out of the reproduction limit of the display device among the photographed colors, and there is an existing method. it can. However, when the existing method is used, there are cases in which conversion and display cannot be performed well depending on the color of a flower having a very bright color. On the other hand, although there are many variations in flower color, there are almost no flowers with colors close to green. Paying attention to this characteristic,
For color regions that do not exist as flower colors in the color space, the conversion of pseudo display should be coarse, while for color regions where flower colors exist, conversion should be performed accurately so that subtle differences in the colors are reflected. Accordingly, it is possible to perform display in which a subtle difference in color can be recognized, including the color of a flower outside the reproduction limit of the display device.

[Fourth Embodiment] In this embodiment, in addition to the above-described embodiment, by applying a color light generation device capable of generating the color light of the color from the spectral reflectance, the color and color of the flower can be improved. The chart color is reproduced on the client side. FIG. 10 shows the system configuration of the fourth embodiment of the present invention. 4, the same components as those of FIG. 4 are denoted by the same reference numerals, and description thereof will be omitted.

The system shown in FIG. 10 has a configuration in which a color light generation unit 203 for generating the color light of the color from the spectral reflectance is added to the client side 200 of the system shown in FIG. FIG. 11 is a flowchart of the operation of the fourth embodiment of the present invention. The operation different from that of the above-described embodiment is that the client 200 generates and displays the color light of the color of the object in step 408, and generates and displays the color light of the color chart in step 409.

Since the colors registered in the color chart are finite, it is not possible to transmit even information on subtle shades.
Therefore, it is ideal that the client 200 can reproduce the color of the flower itself. In addition, since the work of searching for a color chart is complicated, it is convenient if the color of the designated color chart can be displayed immediately. As an apparatus for realizing these functions, a color light generation unit 20 is used.
3 is provided.

The principle for realizing the color light generation unit 203 will be described below. First, an example of the principle of generating color light of the spectral spectrum from the spectral data will be described. FIG. 12 is a diagram for explaining the principle of color light generation according to the fourth embodiment of the present invention. The wavelength slit is adjusted according to the value at each wavelength of the spectral distribution to be generated, which is continuously separated by a prism or the like of light from a known white light source. By causing the light passing through the slit to undergo multiple reflections in the integrating sphere, the light entering the integrating sphere is mixed in color, and the light leaking from the extraction window becomes light having a designated spectral distribution.

If the color light generated according to the above principle is adjusted so as to match the colors of the color chart, and the slit situation value is stored at the time when the colors are matched, the color number of the color chart is designated. As a result, color light of that color can be generated. By using the color light generation unit 203, the color of the flower can be reproduced on the client side 200, and the color of the flower can be more intuitively understood.

[Sixth Embodiment] In the above-described first to fifth embodiments, a flower has been described as an object. In this embodiment, a case where remote meeting support is performed will be described. The objects of the remote meeting include interior design (furniture, fittings, wallpaper, etc.), architectural planning, and design of industrial products such as automobiles.

In the following embodiment, an example in which a remote meeting is performed for an interior design will be described. FIG.
5 shows a service image according to the sixth embodiment of the present invention. The image shown in the figure is for a meeting regarding interior design by connecting to a remote location. It is largely divided into a center-side device (a place where there is a real thing such as furniture) and a client side (a remote participant side), and these are connected so that information can be exchanged using communication means.

The devices on the center side are a lighting device A, a camera,
The system is composed of a spectrum photographing device (such as a spectrophotometer) and a personal computer, and the client-side device is composed of a lighting B, a personal computer, a display device (such as a monitor), a color light generation device, a color chart, and the like. Details of individual functions will be described later as necessary. This system transfers the image of the object to be a product, detailed information on its color, information on price and material, etc. from the center side to the client side, and transmits this information in an optimal form on the client side display device. By displaying, we provide the information necessary for design and purchase decisions accurately. Participants on the client side can judge the color balance with other interiors and the price of the quality without seeing the real thing on site.

The outline of the processing will be described below with reference to FIGS. 4 and 5. Step 101) First, an image of an object to be a product is photographed by the image photographing unit 101 of the center-side apparatus 100 under the illumination light A, and is inputted from the image data input unit 102 to the computer. Step 102) Separately from step 101, the spectral distribution of the color of the target object (spectral reflectance: reflectance of light at each measurement wavelength) using the spectral reflectance measuring unit 103 (spectral measuring device).
Is measured and input from the spectral reflectance data input unit 104 to the colorimetric value calculation unit 150 and the color number determination unit 160. As a spectrum measuring device, an existing spectrophotometer may be used, or a combination of a flash device, a plurality of bandpass filters, and a CCD camera may be used to perform the measurement by changing the filter and photographing a plurality of times.

Step 103) Colorimetric value calculation section 150
Calculates the colorimetric value of the color of the object using the measured spectral reflectance of the object. The colorimetric value is a value obtained by quantifying only the color information while ignoring the brightness information.
IE (International Commission on Illumination) xy colorimetric display is most common. For how to calculate the color value from the spectral reflectance,
References (Noboru Ota, “Basics of Color Reproduction Engineering”, Corona,
It is described in various documents such as pp. 8 (first line) to pp. 12 (last line).

Step 104) Next, the color number judging section 1
At 60, the corresponding color in a commonly used color chart (Munsell color chart) is determined using the spectral reflectance of the object. The following two methods can be considered as a method of determining the corresponding color from the spectral reflectance. (1) Colorimetric values measured for all colors in the color chart are stored in a database, and the colorimetric values calculated for the measured object are matched with the database, and the color having the closest colorimetric value is obtained. Select a chart color.

(2) A human looks at the object and determines the corresponding color number on the color chart. Then, the spectral reflectance of the object is measured, and case data in which the spectral reflectance is associated with the color number of the color chart is accumulated. Now, assuming that the total number of measurement wavelengths in the spectrum measurement is N, these accumulated data can be regarded as a set of points in a case having a color number as attribute data in an N-dimensional space. It is considered that a certain cluster is formed for each color number. Therefore, it is only necessary to determine which color number of the newly measured spectral reflectance data of the target object is close to the cluster of the case of the color number in the set of points of this case. As a method for realizing such a determination, a statistical method such as discriminant analysis or a method using a neural network can be considered.

An example of a method of determining a color number by a statistical determination method will be described below. The processing is roughly divided into three phases. FIG. 16 is a flowchart of the operation of collecting case data in the color number determination method according to the sixth embodiment of the present invention. It is assumed that each symbol has the following content as a premise of the following description.

T: total number of case data J: total number of categories (total color number) C _j : j-th category (corresponding to color number) n _j : total number of cases included in C _{j dj} : up to category C _{j of} unknown data Distance E _t : t-th case data = (R ^t ₁ , ^{_{R t 2 ,,, R t N,}} D t) R t k: k -th reflectance measurements at a wavelength of D ^t: corresponding to the assigned category numbers (color number) N: measurement wavelength points Total M: unknown data = R ₁ , R ₂ , ..., R _N ) R _k : Measured reflectivity at k-th wavelength N: Total number of measured wavelength points Statistical data storage variables (mean and variance of j-th category) S _j = (m ^j ₁ , m ^j ₂ ,,, m ^j _N ) V _j = (v ^j ₁ , v ^j ₂ ,,, v ^j _N ) N, j is the same as above. This is the case data collection phase. Here, the spectral reflectance of the object is measured (steps 601 to 605), and the object is viewed by a human and compared with a color chart, whereby the human determines the color number and determines the color number. Input to the computer (steps 606 to 607). Thus obtained,
A set of the spectral reflectance data of the object and the data of the color number determined by a human is stored in the case database (steps 608 to 609).

In the second phase, the case data obtained in the phase 1 is analyzed and learned to obtain information on the distribution in the N-dimensional space for each color number (for each category). As the information on the distribution, an average value and a variance value in the N-dimensional space for each color number (category) are calculated. FIG. 17 is a diagram showing a process of acquiring statistical data using case data according to the sixth embodiment of the present invention. The left side of the figure is the process of calculating the average value, and the right side is the process of calculating the variance.

The calculated average value and variance value for each category (color number) are stored as statistical data. In the third no-phase, when a measurement value (spectral reflectance) of an unknown object is given using statistical data, a corresponding color number is determined. Here, as shown in FIG. 18, the distance is obtained from the measured value of the unknown object, that is, the distribution of each category of the case data of the point in the N-dimensional space, and the category (color number) having the shortest distance is obtained. Output as color number of unknown object. FIG. 16 shows an example of using the weighted Euclidean distance as a method of calculating the distance from the distribution of each category of the case data.

The weighted Euclidean distance d is a measured value of the unknown object spectral reflectance M: = (R ₁ ,
R ₂ ,,, R _N) distribution mean S _j of: = and the _{(m 1, m 2 ,,, m} N) variance V _j :-( v ₁ distribution, v ₂ ,,, v _N) If

[0080]

(Equation 1)

Is defined as As a result, it is possible to calculate a distance that reflects a variation in distribution for each category. Note that the statistical discrimination method is generally used in various other situations such as character recognition, and has various variations and various ideas. Other general statistical discriminant methods are described in detail in the entire reference (Kenichiro Ishii et al., "Easy Pattern Recognition", Ohmsha).

When a neural network is used, the spectral reflectance of the integrated case data is used as input data (input to N units) of a three-layer neural network, and the color to which it belongs belongs as teacher data, and the error back propagation method is used. By learning with, a function approximating the distribution of the case data in the N-dimensional space can be obtained. By inputting the newly measured spectral reflectance data of the object to the learned neural network, it is possible to determine which color number the object belongs to.

The discrimination by the neural network is described in a reference document (Yuichiro Anzai, "Iwanami Lecture on Software Science Recognition and Learning", Iwanami Shoten, pp.329-346). By using these methods, the color number of the corresponding color in the color chart can be determined from the spectral reflectance of the object. If an expert who is skilled in looking at the color chart is at the center, the expert does not necessarily determine the corresponding color using a computer, but the expert compares the color chart with the object to determine the color number of the corresponding color. The result may be input to a computer.

Step 105) Then, in the data transmitting section 170, in addition to the image data of the photographed object, the calorimetric value information of the calculated object, the determined color number, and the object such as the price and the cloth are determined. The attribute data is transferred to the computer on the client side 200 using the communication means.
Next, the client side 200 will be described.

Step 106) Client side 200
Are waiting to receive data from the center 200 and receive the data. Step 107) If the data reception is completed, proceed to step 108; otherwise, proceed to step 10
Then, the process goes to 6 to wait for reception. Step 108) Display the received image data of the object and the attribute data on the object on the display device. With regard to the color number in the color chart among the transferred attribute data, if the actual color chart is prepared on the client side 200, the color can be intuitively understood.

[0086] The above data transmission and reception are as follows.
A method in which data is transferred only when requested by the client 200 may be used. Further, when displaying an image of an object on the client side 200, the image is displayed so that the position of the object whose spectral reflectance has been measured can be specified, thereby assisting in color quality determination.

The purchaser judges the quality and price by looking at the displayed image and attribute data, and places a purchase order as necessary. The purchase order is input by the purchaser to the computer on the client side 200, and the input purchase order is transferred to the computer on the center side 100 by communication means and accepted. [Seventh Embodiment] In the above-described sixth embodiment, the colorimetric value information, the color number, and the information such as the price and the cloth of the object are used as the attribute data relating to the object. In addition to the above, the color grade of the object is determined to be one of the attribute data relating to the object.

Hereinafter, description will be made with reference to FIGS. 6 and 7 of the second embodiment. In general, agricultural products such as fruits and vegetables are graded according to their various properties (size, sweetness, etc.), and the grade information helps to determine quality and price. In addition, the color of an artificial object such as a used car is closely related to quality and price. In the present invention, the size and shape information can be obtained from the image by transferring the image of the object.

On the other hand, color information cannot be sufficiently conveyed by the image alone due to the limitations of the photographing device and the display device. In the sixth embodiment, the colorimetric value information of the object, the color number, etc. And helped the quality judgment. However, there are cases where the quality cannot always be easily determined only by the information such as the colorimetric value information and the color number of the target object. Therefore, the quality of the color is evaluated and the grade of the color is determined, so that the quality of the color can be easily determined.

As a method of realizing the color grading, an expert on the object is asked to see the real object, and the grading is subjectively determined, whereby the grading information and the spectral reflection data of the object are obtained. By accumulating the sets and applying the determination method as described in the sixth embodiment, the classification can be performed based on the color (spectral reflectance) of the object.

[Eighth Embodiment] In the sixth embodiment, the image of the object is simply photographed, transferred, and displayed. However, in the present embodiment, the influence of illumination at the time of photographing the image, the image display environment, and the like. By displaying the effect of illumination and a color outside the display limit of the display device in a pseudo manner, an image display that looks natural can be realized.

Humans can carry out stable color recognition unconsciously by excluding the influence of the lighting conditions of the environment in which they are placed (color constancy). However, when an image captured under a certain illumination is displayed in an environment with different illumination conditions, the color constancy does not hold, and a color resulting from a difference in the illumination conditions is added. In interior design, it is important to accurately determine the color of an object, and it is necessary to eliminate such a color shift. On the other hand, an image photographing apparatus and a display apparatus each have a limit in the colors that can be reproduced, and these are generally different. In the case of man-made objects such as furniture, there are those of very bright colors, and it is often difficult to display. Therefore, it is necessary to simulate the colors of the captured colors that are outside the reproduction limit of the display device.

As a method of eliminating the color of the illumination light at the time of photographing, a white balance function provided in the photographing apparatus itself (automatically adjusts the color so that the saturation of the low chroma portion in the image approaches 0). To adjust). If the spectral characteristics of the illumination light are known, the tint of the illumination light can be eliminated by dividing the pixel value of the corresponding wavelength of the captured image by the spectral value of the illumination for each wavelength.

The spectral characteristics of the illumination light can be measured by using a radiation photometer. If the spectral characteristics of the light source of the illumination light are known in advance, the data can be used. In order to eliminate the influence of the lighting condition of the place where the display device (image display unit 201) of the client side 200 is placed, the color displayed on the display device under the lighting condition is adjusted to look natural. do it. Generally, commercially available computers and display devices (monitors) have a function for easily performing such color adjustment, and this function may be used.

There is an existing method for pseudo-displaying a color out of the reproduction limit of the display device among the photographed colors in the color conversion unit 230 of the client side 200, and there is an existing method. it can. [Ninth Embodiment] In the above-described eighth embodiment, the sixth and seventh embodiments are described.
In addition to the embodiment, the color of the object and the color of the color chart are reproduced on the client side by applying a color light generation unit capable of generating the color light of the color from the spectral reflectance.

Since the colors registered in the color chart are finite, it is not possible to transmit even information on subtle shades.
Therefore, it is ideal that the client 200 can reproduce the color of the flower itself. In addition, since the work of searching for a color chart is complicated, it is convenient if the color of the designated color chart can be displayed immediately. As an apparatus for realizing these functions, a color light generation unit 20 is used.
3 is provided.

Also, each component of the center side 100 and the client side 200 shown in each configuration diagram of the above-mentioned first to tenth embodiments is constructed as a program, and a disk connected to each computer is provided. The present invention can be easily realized by storing it in a device, a portable storage medium such as a floppy disk, a CD-ROM, or the like and installing it when implementing the present invention.
