Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an IC color display card suitable for use in place of a color sample printed with many different colors on a paper surface (card).

[Conventional technology]

Colors are complex and there are countless combinations of colors, but there is only one hue (H=h
ue), brightness (V=value), saturation (C=chr
.

If you organize based on the three elements of ma), you can arrange them in the correct order. The Munsell color system specified by the Japanese Industrial Standards uses the above three elements as numbers in the format HV/C (
It is expressed as a numerical value).

In this color system, the hue wheel is divided into 100 parts, and each part is further divided into halves as necessary.

In other words, in the Munsell color system, red (R), yellow (Y), green (G
), blue (B), and lily (P), with yellow-red (YR), green-yellow (GY), blue-green (BG), Bizen (PB), and red-purple (RP) in between. ) to divide the color into a total of 10 hues, and each hue is further divided into 10 equal parts and numbered to divide the colors. Therefore, according to this division method, the hue of the color most likely to be red is SR, and the hue of the color most likely to be green is 5G.

Further, as a measure for indicating the brightness V, the brightness of the achromatic color N ranging from white to black is divided into 10 equal parts, with white being 10 and black being O, but it may be further divided and a decimal point is added. Further, in the scale of chroma C, an achromatic color is set as 0, and numbers 1, 2, 3, etc. are sequentially assigned as the purity increases with the same sensory difference.

In this way, the Munsell color system indicates colors in decimal notation, so it is possible to specify colors in detail. For example, if a commonly used color name is expressed in the Munsell color system (HV/C), orange is r10R~6
YR15,5~7/10~14'', pink is r4RP
~8R56,5~871~7.5'', and it is understood that although they are all the same color, they refer to a fairly wide range of colors.

Therefore, to specify a color using the Munsell color system, a standard color chart (color sample) that accurately prints the displayed color is required, and when deciding on the colors of various products, refer to this color sample. I had decided.

[Problem that the invention seeks to solve]

However, as mentioned above, one color is complex and there are many, so naturally there are many color samples printed with these colors, so it is difficult to find the color you need from among these many color samples. It is very troublesome to take out the color samples, and when deciding on the color of a product while looking at color samples while out and about, it is a hassle to carry multiple color samples to each destination. Furthermore, extremely advanced printing technology is required to accurately print a large number of color samples, and printed color samples are prone to discoloration due to dirt or fading due to use, making it difficult to maintain accurate colors. There were various problems.

Therefore, the technical problem of the present invention is to be able to easily and accurately display required colors based on the Munsell color system, to be compact and extremely convenient to carry, and to be able to display accurate colors indefinitely. It's about providing something.

[Means for solving problems]

The measures taken in the present invention to solve the above technical problems are as follows.

(1) Provide a key on the engineering C card for inputting the three elements of color: hue, lightness, and saturation according to the Munsell color system.

(2) Provide a display on the same IC card to display the numerical values of each of the three key-input elements.

(3) On the same IC card, a color display device that actually displays the color combination determined by the above three elements on a liquid crystal display is provided.

However, the numeric values of each of the three elements inputted using the keys herein mean symbols expressed by numbers in the format HV/C inputted using the keys based on the Munsell color system.

[Effect]

Each of the above elements (1), (2), and (3) operates as follows.

■The element (1) above can be expressed by operating the keys provided on a conveniently portable IC card.1For example, if you want to express a light purple color, the hue (H
) to “9・OP”, brightness (V) to “7・o”, saturation (C
), enter ro ・6J. Also, if you want to specify a slightly different color even though it is the same light purple, you can add or subtract the numerical values of each three elements by key operation, for example, "5, OP, 7, 0/6, Oj. You can easily specify the desired color.

(2) For the above element (2), each numerical value (symbol) of the three key-input elements is displayed and visually checked to judge whether it is correct or not.

■Element (3) above actually displays the color specified by the three key-input elements on the LCD, allowing you to visually compare and judge the color in the same way as a color sample, and there is no need to worry about discoloration due to dirt or fading. .

As described above, the above-mentioned technical problem can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.
