[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image information display device, an information reading device, and an information delivery method, and more particularly to an image information display device, an information reading device, and an information delivery method for displaying and delivering information in a two-dimensional code.
[0002]
[Prior art]
Conventionally, a bar code represented by an image in which information is coded has been used as means for transferring various information. Bar codes are used not only for physical distribution but also for all types of information media that can be restored.
[0003]
In recent years, various barcodes such as one-dimensional barcodes and two-dimensional barcodes have been proposed, and the information that can be stored in barcodes is not limited to numerical information but can handle information with a large amount of information in the Mbyte order. It has become possible.
[0004]
[Problems to be solved by the invention]
In recent years, as the amount of information increases, the barcode size has increased. The information represented by the barcode is decoded by analyzing the image information obtained by reading the barcode with an imaging device such as a CCD. However, since the processing capability of a processing device such as a CPU for processing image information does not reach the current technical level with respect to the amount of image information obtained by the imaging device when decoding an enlarged barcode, As shown in FIG. 12, the decoding time increases exponentially, the amount of information transmitted and received increases, and the larger the barcode size, the faster the information represented by the barcode is decoded. There is a difficulty that can not (see http://www.barcode.co.jp/apply/check.html).
[0005]
In addition, when recording barcodes on a recording medium, the larger the code size, the higher the density unevenness and the error rate associated with scratches, which means that larger correction data must be printed. is there.
[0006]
Further, when a plurality of code images are arranged in order to send and receive a large amount of information, the reading means for reading the code images must move to the respective bar code positions. Initial settings such as light amount correction for the background portion and the image portion must be repeated, and there is a drawback that it takes time.
[0007]
In light of the above, an object of the present invention is to provide an image information display device, an information reading device, and an information delivery method that can accurately and quickly read code information with a large amount of information.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, an image information display device according to claim 1 is provided. A code image having a fixed display area, a positioning image area, and a change image area; and Code image in which input information is coded The Code image information to display Based on the input information Code image information generating means for generating; Corresponding to a pixel area corresponding to the fixed display area and a pixel area corresponding to the positioning image area displayed in advance with a fixed density and a fixed hue, and the change image area where at least one of density and hue can be changed. Pixel area to be provided An image display medium; Based on the code image information generated by the code image information generating means, the change image of the image display medium is displayed such that at least one of the density and hue of the pixel area corresponding to the change image area is changed and displayed. Display control means for controlling display of a pixel area corresponding to the area; It is equipped with.
[0009]
In the invention of claim 1, the code image information generating means generates code image information for displaying the information as coded image information, The change in which at least one of the pixel area corresponding to the fixed display area, the pixel area corresponding to the positioning image area, and the density and hue displayed by the display control unit in advance with a fixed density and a fixed hue is changeable. A pixel area corresponding to the image area is provided. Image display medium The display of the pixel area corresponding to the changed image area of the image display medium is controlled so that at least one of the density and the hue of the pixel area corresponding to the changed image area is changed and displayed. .
[0010]
In the present invention, since the code image information is displayed on a rewritable image display medium, a code image representing different information can be displayed on the same image display medium. Therefore, the initial setting is performed only once on the reading side. In addition, different types of information can be efficiently read without moving the reading position. Therefore, a large amount of information can be sent and received quickly.
[0011]
In addition, the present invention of When the image information display device is used as a code indicating the price of a product or used in logistics, the contents of the code image displayed on the image information display device can be rewritten. Is.
[0012]
Preferably, as described in claim 2, the code image information generation unit divides the input information into a plurality of pieces when the amount of input information is larger than a predetermined amount, and the division Code image information is generated for each piece of information.
[0013]
When reading a code image representing information with a large amount of information, since the occurrence rate of errors due to density unevenness and scratches increases, the reading accuracy decreases and the decoding time increases exponentially. Code image information is generated so that a large amount of information is divided into a plurality of pieces and represented by a plurality of code images having a small amount of information.
[0014]
Since each code image has a small amount of information, there is no decrease in reading accuracy due to uneven density or an increased error rate due to scratches, so that information can be sent and received accurately, and decoding time Therefore, transmission / reception can be performed quickly.
[0015]
In addition, since the decoding time of each code image is short, a configuration in which a plurality of code images with a small amount of information are read and processed as one information is compared with a case where the code images are represented by one code image. Thus, the decoding time can be shortened. In addition, by using a code image with a small amount of information, the error occurrence rate due to density unevenness and scratches in each code image is reduced, and information can be accurately transferred.
[0016]
In this case, as described in claim 3, The display control means corresponds to the change image area so that the display of the change image area is switched and displayed every predetermined time based on the code image information generated for each of the divided information. Control the display of the pixel area Or as described in claim 4, Corresponding to a pixel area corresponding to the fixed display area and a pixel area corresponding to the positioning image area displayed in advance with a fixed density and a fixed hue, and the change image area where at least one of density and hue can be changed. A pixel area to be provided for each different area of the image display medium, and the display control means applies each of the pixel areas corresponding to the change image area based on the code image information generated for each of the divided information. Control the display of the pixel area corresponding to the changed image area so that it is displayed simultaneously. It can be configured as follows.
[0017]
By the way, the pixel area corresponding to the fixed display area of the code image and the pixel area corresponding to the positioning pixel for determining the position of the code image do not change with time and are always in the same state. Therefore, in the invention according to claim 5, the pixel area corresponding to the fixed display area of the code image and the pixel area corresponding to the positioning pixel for determining the position of the code image are set to a fixed density and a fixed hue. It is said.
[0018]
Preferably, the pixel area corresponding to the fixed display area of the code image and the density and hue changing function of the pixel area corresponding to the positioning pixel for determining the position of the code image are removed. It is preferable because the configuration of the image display medium can be simplified.
[0019]
In addition, as such a code image, Claim 5 As described in the invention, the code image is one of a one-dimensional barcode and a two-dimensional barcode. Images with This is preferable.
[0020]
Further, the image display medium used in the present invention may be a rewritable display medium such as a liquid crystal, for example. Claim 6 As described above, the image display medium is enclosed between a pair of substrates disposed opposite to each other, a plurality of electrodes disposed on each of the pair of substrates and disposed opposite to each other, and the pair of substrates. And a group of colored particles that move between the substrates according to a predetermined potential difference generated between the electrodes arranged opposite to each other, and adhere to one of the pair of substrates; And the display control means includes Of the plurality of electrodes, based on the code image information Pixel area corresponding to the change image area So that a predetermined potential difference is generated between the electrodes facing each other. A voltage is applied to control display of a pixel area corresponding to the changed image area Constitution When Good.
[0021]
Since an image display medium that displays an image with such particles represents an image with particles attached to the substrate, the image being displayed is fixed. Therefore, an image with high contrast can be obtained. In addition, unlike an image display medium configured to form an image by scanning light, the display state of the image is always fixed, so that the image moves during reading on the reading side, and some information cannot be read. There is no. Therefore, accurate reading can be performed regardless of the reading speed and reading method on the reading side.
[0022]
Also, Claim 7 As described in claim 1, Claim 6 In the image information display device according to any one of the above, Display control means Is In the image display medium Based on image data Image display When done Both based on the code image information Displayed based on image data In the image The display of the pixel area corresponding to the changed image area included in It can be constituted as follows.
[0023]
Claim 7 In the invention described in (1), the code image is incorporated into the image based on the image data. With this configuration, for example, the information represented by the code image can be displayed as an image that can be understood by the user, and the user can be notified of the general content of the information represented by the code image. An image based on the image data can also be used as an advertisement, for example. In this case, when the user obtains the information represented by the code image, the effect as an advertisement is great because the user always sees the image in which the code image is incorporated.
[0024]
Claim 8 The invention described in Claim 7 In the image information display device described in the above, Display control means Is Displayed on the image display medium The image data is rewritten according to the type of code image. For example, when the code image displayed on the image display medium represents what is represented by an image different from the code image, what the code image represents when the information represented by the code image is rewritten. It is possible to rewrite the image indicating whether or not. Images can also be used for advertising purposes.
[0025]
In addition, for example, by viewing the relevant advertisement, accessing detailed information, obtaining detailed explanations of paintings and works of art, obtaining detailed information on visually appealing media, or using necessary information in the same place The information can be selected in various situations depending on the person.
[0026]
Also, Claim 9 The information reading apparatus according to the invention described in claim 1 to Claim 8 The image information display device according to any one of The image display medium An information reading device for reading and decoding a code image displayed on the image reading means, reading means for reading the code image displayed on the image information display device, and decoding means for decoding the code image read by the reading means And.
[0027]
The reading means can be constituted by, for example, a reading means for reading an image such as an image sensor, and preferably, the read image is digitized digital data, and the decoding means is configured to decode original information from the digital data. good. Such an information reading apparatus may be manufactured in the manner of reading a code image, or an apparatus with an image reading function, such as a digital camera, a personal computer with an image reading function, or a telephone with an image reading function. Can be assembled. Since the number of users can be easily increased by incorporating it into a device having other functions as described above, the code image can be used for various purposes.
[0028]
In addition, when a large number of users collect and send information on a communication network such as a wireless network, the transfer paths are concentrated on one, which places a heavy load on some processing systems in the communication network and hangs the system. May not be able to provide sufficient services to users.
[0029]
In addition, for example, the audience visits places such as airports, stations and other places where transportation facilities are used, places where portable wireless devices such as concert halls and hospitals are not available, odds of winning voting on a racetrack, and progress of other stadiums The above phenomenon occurs when appropriate information required by the user is diverse, diverse and concentrated in a place where different information is required.
[0030]
Also, in such a place, although the advertising effect is great, providing the service is the most important content for the advertising medium, so the unavailability of the system due to the hangup has a bad image and must be treated the best Therefore, it is an important issue to easily attract attention by users and to convey information on products and services to users.
[0031]
Therefore, Claim 10 The information delivery method of the invention described in A code image having a fixed display area, a positioning image area, and a change image area; and Code image in which input information is coded The Code image information to display Based on the input information Generate Corresponding to a pixel area corresponding to the fixed display area and a pixel area corresponding to the positioning image area displayed in advance with a fixed density and a fixed hue, and the change image area where at least one of density and hue can be changed. Pixel area to be provided In the image display medium, Based on the generated code image information, change and display at least one of the density and hue of the pixel region corresponding to the changed image region, The code image displayed on the image display medium is read and decoded.
[0032]
In the present invention, the code image displayed on the rewritable image display medium is read and decoded. In other words, since a wireless communication network is not used, there is no problem such that the load on the server due to concentration of access increases and reading becomes impossible, and information can be transmitted and received reliably. In addition, information can be transmitted even in places where many precision devices such as hospitals are used without causing problems such as radio waves for transmitting and receiving information affecting the devices.
[0033]
In addition, when an image such as an advertisement is displayed together with a code image, the system will not be hung up due to the hang-up, and the problem will not occur such as the image will be deteriorated or the information cannot be used. .
[0034]
further, Claim 11 In the invention described in Claim 10 In the information delivery method according to claim 1, Entered When the amount of information is larger than a predetermined amount, the input information is divided into a plurality of pieces, and each piece of divided information is divided. Code image information is generated, and the display of the change image area is controlled based on the code image information generated for each of the divided information.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of an embodiment to which an image information display device, an information reading device, and an information delivery method are applied will be described in detail with reference to the drawings.
[0036]
(First embodiment)
In the present embodiment, as shown in FIG. 1, an image display device 11 that displays a one-dimensional barcode 13 on a rewritable image display unit 10 is shown. The one-dimensional barcode 13 is information obtained by coding the result of another ball field that changes over time, for example, and the displayed one-dimensional barcode is read by a reading device such as a commercially available barcode reader, After being converted into digital data, it is decrypted and obtained as original information based on a plurality of decrypted data.
[0037]
As shown in FIG. 1, the image display device 11 includes an image display unit 10, a voltage control unit 12 for forming an image on the image display unit 10, and a control unit 19.
[0038]
The image display unit 10 is a general liquid crystal display device. In the present embodiment, the image display unit 10 and the voltage control unit 12 are configured to be detachable, and the image display unit 10 displays a one-dimensional barcode 13. It can be carried by, for example, used as a product tag.
[0039]
The control unit 19 stores a program for performing various controls of the image display device 11, and as shown in FIG. 2, a data input unit 70, a digital data buffer 71, a code data conversion unit 72, a code data buffer, and the like. 73, a code creation unit 74, and a code information storage unit 75.
[0040]
The digital data input from the data input unit 70 is temporarily stored in the digital data buffer and then output to the code data conversion unit 72. The code data conversion unit 72 converts the input digital data into code image information and outputs the code image information to the code creation unit 74. When the input code image information is larger than a predetermined amount, the code creating unit 74 divides the code image information by a predetermined unit of information amount to obtain a plurality of code image information, The data is output to the buffer 73. At this time, by storing a plurality of pieces of code image information with a small amount of information obtained by division in the code information storage unit 75, the same code information can be controlled to be displayed a plurality of times.
[0041]
The code data buffer 73 temporarily stores the code image information from the code creation unit 74 and then outputs the code image information to the sequencer 76 constituting the voltage control unit 12. Thereby, an electric field is formed between the electrodes of the image display unit 10 in accordance with the code image information, and a barcode as shown in FIG. 1 is displayed on the image display unit 10.
[0042]
In this embodiment, since the two-dimensional barcode based on the divided code image information is sequentially displayed by the sequencer, the two-dimensional barcode is changed and displayed on the image display unit 10 every moment. It will be.
[0043]
The barcode image has an area that does not change with time. Since such an area does not need to have a function of changing an image, in the present embodiment, a liquid crystal is not contained and is created in advance as a still image. Of course, when there is a case where it is used for the contrast expression of the white background portion and the black background portion, the same configuration as that of the change image may be used.
[0044]
Here, the region that does not change with time corresponds to, for example, a quiet zone (see FIG. 3) for a one-dimensional barcode and a position determination mark (arrow portion in FIGS. 4 and 5) for a two-dimensional barcode.
[0045]
In particular, in the case of a two-dimensional barcode, the position accuracy of the symbol is a big problem, and reading of an image for position determination is more important than reading of the entire image. Therefore, as shown in FIG. 5, by creating an image portion corresponding to position determination with a pattern of paper and an outer frame, it can be used for a barcode image.
[0046]
(Second Embodiment)
Although liquid crystal is used in the first display device, the time required to drive one screen of the current barcode reader is 0.2 to 0.3 sec. Therefore, it is necessary to continuously output the same image. Further, when installed outdoors, there is a problem that the amount of display light is small and it is difficult to obtain contrast. Therefore, a display device having image retention and high contrast is required.

The two-dimensional barcode 14 displayed on the image display unit 10 is imaged and converted into digital data. The obtained digital data is input by the code image input unit 80, converted into image data by the image data conversion unit 81, and then temporarily stored in the image data buffer 82.
[0068]
At the time of transmission / reception of large-capacity information, the imaging device 18 reads a plurality of two-dimensional image data representing small-capacity information, so which information is part of the data input from the code image input unit 80. It is necessary to judge. Therefore, the data recognizing unit 83 collects the image data stored in the image data buffer 82 for each piece of data image information representing one piece of information and outputs it to the data reverse converting unit 85.
