Abstract

The hidden image formation method of hiding identification phrases such as product information or service information so that they cannot be identified with the naked eye using differences in brightness and saturation of different patterns and colors is a process of forming a background with low saturation and low brightness. Forming a low-saturation and low-brightness identification phrase with a similar color on the base, and forming a first pattern in which the low-saturation and low-brightness symbol having a similar color to the background is arranged in a horizontal direction so that kerning and line spacing are constant. And forming a second pattern in which the symbols of color having high saturation and high brightness are arranged in concentric circles on the identification phrase and the first pattern. The hidden image thus formed is detected by an opaque identification tool having a color similar to the symbol and the identification character of the first pattern.

Description

Hidden image formation and detection method {METHOD OF FORMING AND DETECTING HIDDEN IMAGE}

The present invention relates to a method for forming and detecting a hidden image, and more particularly, to forming a hidden image that hides identification phrases such as product information or service information from the naked eye by using differences in brightness and saturation of different patterns and colors. The present invention relates to a hidden image detection method for identifying such hidden images through a simple identification tool.

Hidden images are those which are sold or donated to a specific person in a form that cannot be seen by a user, and thus, hidden contents can be identified according to a predetermined procedure, and technology for providing such hidden images has become very popular in recent years.

A representative example of hidden images is instant lottery tickets. Instant lottery is a form of identifying hidden contents by coating specific information with silver foil and removing silver foil using the side of coins. Such a hidden image is also applied to the advertising and promotion strategy a lot, such a hidden image is often used in prizes, coupons, and the like.

More recently, a hidden image using saturation and lightness has been provided. As an example, U. S. Patent No. 5,984, 367, entitled “Hidden Image Game Piece”, prints a substrate on a transparent or translucent substrate in a form that makes it difficult to discern specific information by saturation and lightness, Techniques for identifying hidden information by lightening are disclosed.

However, this conventional technique has a disadvantage in that a medium containing a hidden image is supplied to a user so that the medium containing the hidden image is used only for one-time use. Therefore, in view of the fact that in general, hidden images are usefully used as advertisement and promotion strategies for a product or company, a one-off promotion strategy is likely to be only temporary effect.

Therefore, when using the medium containing the hidden image as described above, the user has to take the hassle of having to obtain such a medium for a new additional service, which leads to a reduction in the promotion effect.

Therefore, there is still a need to find a means of utilizing hidden images as part of a continuous promotion strategy rather than a simple one-time promotion strategy.

The present invention was devised to solve the above problems, and provides a hidden image which can be repeatedly used after providing a hidden image in which a specific identification phrase is hidden by using the brightness and saturation difference of colors together with the difference in the arrangement of the patterns. The purpose of the present invention is to provide a hidden image formation and detection method capable of continuously receiving a service through a hidden image by allowing a user to identify the same.

In order to achieve the above object, the method for forming a hidden image according to the present invention includes a process of forming a background having low saturation and low brightness, and overlapping the identification phrases of low saturation and low brightness having a color similar to that of the background. Forming a first pattern in which the symbols of low saturation and lightness having a color similar to that of the background are arranged in a horizontal direction so that kerning and line spacing are constant, and in a region other than the identification phrase, and high saturation and high brightness And forming a second pattern having a symbol having a color arranged in a concentric shape so as to overlap the identification phrase and the first pattern.

Preferably, the first pattern is formed with a margin of a predetermined size with the identification phrase, and the margin is also preferably about 70% of the text thickness of the identification phrase.

In addition, the background is cyan, the symbol of the first pattern and the identifier is blue, the portion of the symbol and the identifier of the first pattern overlaps with the symbol of the second pattern is gray, the base is the first It is preferable that the part which overlaps two patterns is yellow.

More preferably, the background is a color in which red 51, green 102, and blue 51 are mixed based on the computer graphic color table, and the symbol and the identifying character of the first pattern are colors in which green 102 and blue 204 are mixed. The portion where the symbol of the first pattern and the identification letter overlap with the symbol of the second pattern is a color in which red 203, green 203, and blue 203 are mixed, and the base overlaps with the symbol of the second pattern. Silver 204, green 204, and blue 51 may be mixed colors.

Also, the symbols of the first and second patterns are preferably characters having the same font.

The hidden image forming method of the present invention may further include displaying the hidden image formed by the above processes on the display window of the electronic device.

According to another aspect of the present invention, there is provided a method for detecting a hidden image formed by the above method, wherein an opaque identification tool of a color similar to the symbol of the first pattern and the identification letter is used.

Preferably, the identification tool has a transparency of at least 30% and is also preferably pure blue.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the specification and claims should not be construed as having a conventional or dictionary meaning, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

1 is a view showing a first pattern of the hidden image according to the present invention, Figure 2 is a view showing a second pattern of the hidden image according to the present invention, Figure 3 is a pattern overlapping the pattern of FIGS. It is a figure which shows a state. First, referring to the drawings, each pattern used in the present invention will be described.

First, the first pattern 10 illustrated in FIG. 1 includes a plurality of symbols 12. At this time, the symbol 12 may be made of letters such as alphabets or Korean characters, or may also use numbers or symbols. These symbols 12 are arranged in the horizontal direction so that the leading and the leading are constant.

An identification phrase 20 is formed in the first pattern 10. The identification phrase 20 is difficult to identify with the naked eye and becomes a 'hidden image' which is confirmed by the user only when using a separate identification tool. The identification phrase 20 may be implemented in various ways depending on the purpose of use, may include information such as product information, winning phrases, passwords, it can be applied in various ways.

The second pattern 30 shown in FIG. 2 is made up of symbols 32 arranged radially in concentric circles. As with the first pattern, the symbol 32 can be all letters, numbers, symbols, and the like.

Preferably, the symbols 12 and 32 used in the first pattern 10 and the second pattern 30 may be formed of characters having the same font. In the drawing, as an example, “DESIGN” is continuously arranged. It is shown.

The first pattern 10 and the second pattern 30 are formed to overlap each other, and at this time, visual disturbance occurs by different arrangements of the patterns, thereby significantly reducing readability.

The state where the first pattern 10 and the second pattern 30 overlap each other is well illustrated in FIG. 3.

Meanwhile, the first pattern 10 and the identification phrase 20 have a color similar to that of the ground 1. Therefore, when the first pattern 10 and the identification phrase 20 overlap with the second pattern 30, visual identification is difficult because it is not clearly distinguished by a disturbance phenomenon. In addition, the first pattern 10 and the identification phrase 20 is made of a color having a lower brightness and saturation than the second pattern 30. The first pattern 10 and the identification phrase 20 having low brightness and low saturation are further disturbed by the second pattern 30 having relatively high brightness and saturation. That is, since the second pattern 30 has a color of high saturation and high brightness, the attention of the color is high, and therefore, the first pattern 10 and the identification phrase 20 are relatively first. It is hidden by the two patterns 30. In such a configuration, it is almost impossible to visually identify the identification phrase 20.

Looking at the color of each pattern and identification phrase as described above in more detail with reference to FIG.

4 schematically illustrates a state in which the first and second patterns 10 and 30 overlap with each other. In the figure, the part of Fig. 1 is the base 1 part, and has low saturation and low brightness. Preferably, the portion indicating the background 1 has a cyan color, and more preferably, a mixture of red 51, green 102, and blue 51 based on a computer graphic color table ranging from 0 to 255.

In the figure, the letter “Z” denotes the symbol 12 and the identification phrase 20 of the first pattern 10, and has a color of low saturation and low brightness, and in particular, a color similar to the letter “T” of the ground 1. Preferably, the ridge has a blue color, and more preferably has a mixture of green 102 and blue 204 based on a computer graphics color table ranging from 0 to 255.

In the drawing, the part “㉰” indicates a portion where the symbol 12 or the identification phrase 20 of the first pattern overlaps with the symbol 32 of the second pattern, and has a color of high brightness and high saturation. Preferably, the ridge has a light gray color, more preferably, a mixture of red 203, green 203, and blue 203 based on a computer graphics color table in the range of 0 to 255.

In the drawing, the portion “㉱” indicates a portion where the base 1 overlaps with the symbol 32 of the second pattern, and has a color of high brightness and high saturation. Preferably, the ridge has a yellow color, and more preferably, a mixture of red 204, green 204 and blue 51 based on a computer graphics color table ranging from 0 to 255.

The color distribution of each area is shown in the following table. In this case, the numerical value representing the distribution ratio of each color represents a range value between 0 and 255 of the computer graphic color table.

domain RED GREEN BLUE ㉮ 51 102 51 ㉯ 0 102 204 ㉰ 203 203 203 ㉱ 204 204 51

The color distribution of each area shown in Table 1 was selected so that the hidden image of the present invention is difficult to visually identify, but has an optimal condition that can be identified when using a predetermined identification tool. However, the colors selected above should be recognized as the most preferred example of implementing the invention, but should not be construed as limiting the invention.

In addition, in order to facilitate identification of the identification phrase 20, it is preferable that the identification phrase 20 is formed with a space of a predetermined size and the symbol 12 of the first pattern. 5 shows the margin 14 formed between the identification phrase 20 and the symbol 12 of the first pattern.

Referring to FIG. 5, a margin 14 having a predetermined size is formed around the identification phrase 20, wherein the margin 14 surrounds each stroke of a letter or a symbol constituting the identification phrase 20. Such a margin 14 helps the identification phrase 20 to be more visible when detecting the hidden image through a separate identification tool.

If the margin 14 is too small, the identification is inferior, and if the margin is too large, the identification is too high to identify the identification phrase 20 with the naked eye. The inventor of the present invention, through various experiments, when the margin 14 between the identification phrase 20 and the symbol 12 of the first pattern is in the range of approximately 50% to 100% of the text thickness of the identification phrase 20. It was found that it showed proper discrimination, and was found to have the best effect when the size of the margin 14 was approximately 70% of the identification text thickness.

Such a hidden image of the present invention may be printed or distributed or sold on a general print medium, and more preferably may be displayed through the display window of the electronic device. In this case, the electronic device may include all kinds of electronic products having display windows, such as a monitor or a display panel, and may be particularly suitably used for electronic products capable of transmitting data through wired and wireless communication networks. Examples of such electronic products include computers such as desktops and laptops, as well as mobile phones, PCS, PDAs, televisions, and video. In addition, there may be various applications.

First, the hidden image of the present invention is described as an example displayed on a monitor of a computer as follows. In order to be displayed on a monitor of a computer, the hidden image of the present invention must be created or converted into a computer file. To this end, a producer may create and distribute a hidden image with a computer graphics program, or scan a printed hidden image and convert it into a computer file. In addition, the hidden image converted into a computer file may be distributed through a storage medium such as a floppy diskette, more preferably transmitted to a user through a computer network such as the Internet, or advertising or promotional strategy through a hidden image It may be displayed on the homepage of the operator to be performed.

6 shows an identification tool 50 for detecting a hidden image of the present invention. The identification tool 50 for detecting the hidden image of the present invention may have a form in which the hidden image identification film 52 is built into a board having a portable size, and the board has a through hole for installing the film 52. It must be formed.

In addition, in the blank space of the identification tool 50 except for the film 52 installation area, advertisement and promotional text such as a homepage address and a product guide may be inserted.

The film 52 is made of an opaque material having a color similar to the identifier. In a preferred embodiment of the present invention in which the identifier 20 is blue, the film 52 is also preferably blue, more preferably 100% pure blue with no other mixed colors mixed at all.

In addition, the film 52 may be made of soft PVC, and preferably has a thickness of 2 mm or more. In addition, it is also preferable that such a film 52 has a transparency of at least 30% or more when the total transparency is 100%. When the transparency of the film 52 falls below 30%, detection of the identification phrase 20 is not easy.

When observing the hidden image of the present invention through the identification tool 50 configured as described above, the brightness and saturation of each part color may be changed by the color of the film 52 so that the identification phrase 20 may be read. That is, when observing through the blue film 52, the cyan part which is originally blue is closer to blue, and the C part which is originally blue is kept blue as it is. In addition, the intrinsic portion of light gray is blue, and the intrinsic yellow portion is blue green.

At the same time, the light portion and the light portion are only slightly lowered in brightness when observed through the film 52, but the light and dark portions are significantly lowered. In other words, the parts and parts were hiding the identification phrase 20 due to the color disturbance due to the yellow and light gray with high brightness and saturation, but the color of the parts ㉯, 과 and ㉰, ㉱ by the film 52. The values are almost equal, and thus, the visual disturbance is reduced, so that the identification phrase 20 can be detected.

In addition, the margin 14 formed between the identification phrase 20 and the symbol 12 of the first pattern helps to identify the identification phrase 20 more clearly when color disturbance is reduced through the film 52.

7 shows an example of the application of the present invention, in which a user detects a hidden image of the present invention displayed on a monitor by using the identification tool 50.

In addition, the hidden image shown through the identification tool 50 is shown in FIG. 8. Referring to this figure, the identification phrase 20, which was not visually identified, can be identified when observed through the film 52. It can be seen that.

Therefore, only one identification tool for identifying the hidden image of the present invention is sufficient, and the identification tool can be continuously and repeatedly used for a plurality of hidden images.

The method of forming the hidden image is preferably a method of sequentially forming the base 1, the identification phrase 20, the first pattern 10, and the second pattern 30. Since this transparency is constant, the same effect can be provided even if the formation order is changed. However, each pattern, identification phrase and background should have the arrangement, structure and color as described above.

In addition, such a hidden image may be displayed on a monitor of a computer as described above, and the hidden identification phrase 20 may be detected by overlapping and observing the film 52 of the aforementioned identification tool 50 on the hidden image. do.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

The hidden image according to the present invention configured as described above has an advantage of effectively hiding the identification text containing the service contents by the arrangement difference of each pattern and the brightness and saturation difference according to the color of each pattern.

In addition, since the identification tool for detecting the hidden image can be used repeatedly, only the hidden image needs to be distributed, which is very advantageous for the promotion and promotion strategy using the hidden image.

In particular, when displaying the hidden image of the present invention on a monitor of a computer, there is an advantage that the hidden image can be distributed through the Internet to maximize the promotion and promotion effect.
