The present invention is based on the technology of the existing technology, the applicant's own patent registration No. 10-0385459 and the patent registration technology application No. 10-2005-000476 to realize the encoding and decoding algorithm of the color code (symbolology), electronic recognition possible color channel 2 ^n-bit (bit) in the HTML language color code representing the n color number possible and the C ++ language color code representing a color specification Text electronically represented by represented by the n number of available conventional one dimension of the two-dimensional Recognize the corresponding binary algorithm of binary code recognized in monochrome code (symbol) as color text to compose color code value, and set color code ((symbol)) (e.g. color of 16 bit channel of HTML) It is possible to configure corresponding variables of 281,474,976,710,656 colors to be implemented.

This is a method of converting one-dimensional black and white barcodes (symbols) and two-dimensional black and white codes (symbols) into color codes, and is applied to color code algorithms already registered in each field of information processing using them. 1D, 2D black and white symbology technology provides economical methods to use color codes in general industrial fields in an economical way for more information processing. Reduction of human cost has an advantage that can be applied to new IT information processing field.

Barcode is used for sales management and automatic order management in distribution fields such as department stores, convenience stores, supermarkets, etc., and it is used widely and widely in our daily lives. Of course, it contributes significantly to cost reduction. In addition, in the field of office automation, it is applied to commute management, asset management, and data management, and has a great effect on industrial development.

As such, barcodes are recognized as the best tool for quickly and accurately collecting data in a variety of applications in almost all industries, and the reasons for the adoption of barcodes are paper, vinyl, plastic, fiber, iron plate, ceramic, etc. Dot material printers, laser printers, ink jet printers, band printers, or dedicated bar code printers can be used to express data inexpensively and easily.Pen scanners, CCD scanners, portable laser scanners, and fixed types for each application environment This is because there is an advantage of collecting and processing error-free data in real time using a laser scanner and a mobile phone cam scanner.

In addition, the black and white barcode has a parity check function and a check digit function of the symbol in its structure, so if the barcode is printed more than a certain quality, the probability of data error is extremely low. By providing enough data redundancy, even if a part of a black and white barcode symbol is contaminated or damaged, normal data can be obtained by scanning another part.

However, these information processing functions have a problem of the information recording recognition algorithm (a problem that requires a lot of physical space for the recognition input data to recognize a black and white barcode that can be recognized electronically as a binary number) in order to express a lot of information data in a limited space. Complementary technology is two-dimensional (2D) bar code. The two types are the stacked bar code and the matrix code.

The types of stacked bar codes are PDF-417, Code 16k, Code 49, Codablock, etc.The types of matrix codes are Maxicode, Code 1, DataMatrix, Vericode, ArrayTag, Dot Code, Softstripe.

These codes are currently used technologies that are constructed and developed to get more information in a physically confined space.

In addition, in order to compensate for this limitation of the data processing capacity of the physical space, a technology called color code was developed by a domestic company, and patent applications No. 10-2000-0024203 and 10-2000-0016585 have already been registered. , 10-2000-0022258, 10-2000-0018296, 10-2000-0012748, 10-2000-0025036, 10-2000-0032697, 10-2000-0062597, 10-2000-0055825, 10-2000-0052206, 10-2000-0068378, 10-2000-0024367, etc. have been developed to complement black and white bar code, and the reality that is commercialized will be.

However, as described above, these techniques did not change the technical difference significantly in the fundamental method of recognizing the binary number of the two-dimensional code, and this conventional barcode technology is a technical limitation that is difficult to express much data in physical space. Because of this, current technologies have a problem that they cannot escape the matrix structure to record more information data.

To complement these technologies

Based on the technology of n, it is an electronically expressed color code technology expressed as n number of HTML language color codes and n number of C ++ language color codes that can be generated in the power of two. In order to solve these complex problems, black and white barcodes currently used in the IT field around the world are applied to the corresponding variable of color codes that can be formed from the applicant's already registered color code 2 ⁿ bits. It provides a method for applying color algorithms and black and white barcodes, and uses black and white one-dimensional and two-dimensional (2D) barcodes on personal record electronic cards (credit cards, ID cards, national ID cards, passports, etc.) By applying existing black and white one-dimensional and two-dimensional (2D) bar code to personal electronic record card, iris recognition among electronic recognition technologies that require high cost It replaces technology, fingerprint recognition technology, and RFID chip technology with simple methods, and provides a method for applying a new electronic card to each industry to manage information in a convenient way without a smart card.

The present invention is a method and algorithm for converting a one-dimensional black and white barcode and a two-dimensional black and white barcode into a color code, in order to convert a one-dimensional black and white barcode (symbol) and a two-dimensional black and white barcode (symbol) into color codes. one-dimensional black and white bar codes and two-dimensional (2D) using the principles of black and white bar code recognition of color codes and constitute an algorithm, these algorithms are electronically recognizable color channel 2 ⁿ bits in response to the algorithm consisting of a color code (bit Colors that can be represented on the channel (program-recognizable) are mapped to recognition commands (color codes), and they are recorded as corresponding variable values (data) corresponding to corresponding variables of algorithms entered in the database of each color code. And the color gamut of the electronically recognizable color applied to these variables Of three elements R, G, and the number of combination of light of B (Red, Green, Blue), that is, can be configured, if the dog is n.

The amount of information of the color value of the 8-bit channel can use 16,777,216 colors existing between the colors from (0,0,0), which is black, to (255,255,255), which is white,

The information amount of the color value of the 16-bit channel is represented by 281,474,976,710,656 colors, which are (0,0,0) to (2 ¹⁶ -1, 2 ¹⁶ -1, 2 ¹⁶ -1)

Since the amount of information of the color value of the 32-bit channel is 24 bit color + alpha channel (256 shades of scale), the color of (0,0,0) to (2 ²⁴ +2 ⁸ , 2 ²⁴ +2 ⁸ , 2 ²⁴ +2 ⁸ ) A combination of 1.33 x 10 ³⁶ different colors can be expressed.

As the number of color expressing colors of the computer industry is developing, color recognition technology is being developed to decompose the color, and the segmentation of the electronically recognizable color which is not visually recognizable to human is becoming more sophisticated. The parameter in the case of the color present at suffices to fully satisfy the applicable range of the present invention.

Recognition of the colors described above is not difficult when implementing the text of the electronically recognizable program command, and they express both the color codes with a combination of English and Arabic numerals and special symbols.

That is, even if the number of color-coded language combinations is 1.33 × 10 ³⁶ colors for 8-bit, 16-bit, and 32-bit channels, they can be represented in Html language and C ++ language. In the 16-bit channel, the RGB color coke recognizes colors from (# 0000, # 0000, # 0000) to (#FFFF, FFFF, FFFF).

These color texts require Text from Red values (0000) to (FFFF) and Green values (0000) to (FFFF) and Blue values (0000) to (FFFF). Using the principle of barcodes and two-dimensional (2D) black and white barcodes, the value can be read sufficiently.

In order to achieve the above problem,

In the case of a 16-bit channel, the information amount of color values is represented by 281,474,976,710,656 colors, which are colors of (0,0,0) to (2 ¹⁶ -1, 2 ¹⁶ -1, 2 ¹⁶ -1).

In order to achieve the above object, an algorithm of a one-dimensional black and white barcode and a two-dimensional (2D) black and white barcode that recognizes color text is configured.

This configuration uses the method of black and white bar code recognition already commercialized, and the method of using the color code algorithm may be applied to the algorithm used by each black and white bar code developer, or by implementing a separate color code recognition algorithm. It can also be applied to code algorithms.
