Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile terminal and an advertisement system for easily browsing a home page where a home page address is displayed in an advertisement.
[0002]
[Prior art]
Today, advertiser companies and organizations are established on the Internet for in-car advertisements for trains and buses, indoor / outdoor signboard advertisements, advertisements in magazines, and advertisements displayed on TV. The homepage address (URL) is often displayed.
[0003]
Conventionally, a person who wants to browse a homepage after seeing such an advertisement writes down the URL displayed in the advertisement by handwriting, or inputs it by key operation to a mobile phone, PDA (personal digital assistant) or personal computer. Was.
[0004]
Conventionally, the URL displayed in such an advertisement is not the URL of a home page on which matters relating to the content of the advertisement itself are posted, but the URL of the top page of a home page established by an advertiser company or organization. There were many cases. (In this specification, the entire Web page is called a home page, and the first page of the Web pages is called a top page.)
[0005]
For example, in a classical concert advertisement, the URL of the top page of the homepage established by the concert hall, which is the venue for the concert, is not the URL of the homepage that lists the performers, dates, and admission fees of the concert For example, in the advertisement of an electrical product, the top of the homepage established by the manufacturer that manufactures the electrical product, not the URL of the homepage where the configuration and specifications of the advertised electrical product are posted. For example, the URL of the page is displayed.
[0006]
One reason for this is that the URL of a home page on which matters relating to the content of the advertisement itself are posted often follows a URL of the top page of a company or organization (for example, the URL of the top page of a manufacturer). Is' http: // www. OO. Co.jp ', the URL of the homepage where the configuration and specifications of the advertised electrical products are posted is' http: // www. jp / ○○ / ○○ / ○○ .html '), so it takes up a lot of space when displayed in advertisements (letters get smaller when trying to display in the same space) It is done.
[0007]
Another reason is that the URL of pages other than the top page of the home page is changed relatively (the character part following the URL of the top page is changed), so the home page can be browsed even after the change. It is also possible to display the URL of the top page in order to receive it.
[0008]
Therefore, a person who sees these advertisements and wants to browse a page on which matters relating to the advertising content itself are opened first opens the top page of the company or organization, selects an item from the top page, It jumped to the posted page (in the case of a large company or organization's homepage, it jumped in several steps).
[0009]
[Problems to be solved by the invention]
However, it is troublesome to perform a handwriting operation or a key input operation for a URL displayed in an advertisement, and there is no time for performing such an operation in the case of an advertisement displayed on a screen on a television.
[0010]
For this reason, even if you want to browse the homepage after seeing advertisements, you often get lost without doing such work and you can't browse the homepage.
[0011]
In addition, if you want to browse only the pages that contain information about the advertising content itself (you do not want to browse the top page of the company or organization that is the advertiser), select the item from the top page of the company or organization The task of jumping to a page is still troublesome.
[0012]
In view of the above-mentioned points, the present invention has been made to make it possible to easily browse a home page on which a URL is displayed in an advertisement without performing troublesome work.
[0013]
[Means for Solving the Problems]
  In order to solve this problem, the present applicant shows an imaging unit, an extraction unit that extracts a character string representing a URL from an image captured by the imaging unit, and a character string extracted by the extraction unit. Means for storing informationThe extraction means includes a first process for searching a character string of a predetermined number of characters in which a blank of one character or more does not exist between characters by character recognition from an image taken by the imaging means; A second process for determining whether or not 'http: //', which is a character string used in the head part of the homepage address, exists in the character string found by the first process; If it is determined that 'http: //' exists in the processing of, the character string after 'http: //' up to the point where the character is interrupted or has one or more blanks before is recognized from this image In the third process for determining the character string with 'http: //' added to the beginning of the recognized character string as the character string representing the homepage address, and 'http: //' exists in the second process. If it is decided not to do so, the home string is found in the character string found by the first process. The fourth process for determining whether or not 'www.', Which is the character string used at the beginning of the page address, is abbreviated, and that 'www.' Exists in the fourth process In this case, from this image, the character string after 'www.' And before the character is interrupted or before one or more blanks are recognized, and 'http: // www. The fifth process of determining the character string with 'added as the character string representing the home page address is performed.Suggest a mobile device.
[0014]
When a person who views an advertisement displaying a URL and wants to browse the homepage photographs the advertisement with an imaging means using the portable terminal, a character string representing the URL is taken from the photographed image. Is extracted by the extraction means. Information indicating the character string is stored in the portable terminal.
[0015]
As a result, the homepage is browsed based on the information stored in the mobile terminal (if the mobile terminal itself is equipped with a WWW browser, the mobile terminal itself is browsed and the mobile terminal itself is equipped with a WWW browser. If not, the information can be transmitted to a terminal equipped with a WWW browser and viewed on the terminal).
[0016]
In this way, if this mobile terminal is used, the homepage on which the URL is displayed in the advertisement can be browsed simply by photographing the advertisement without performing the troublesome task of handwriting or keying in the URL. become able to.
[0018]
  In addition, character strings representing URLs such as 'http: //' and 'www.'Focus on a character string unique to the top part of the URLAnd extractEven when characters other than the URL displayed in the advertisement are photographed by the imaging means together with the URL, only the character string representing the URL can be extracted from those characters.The
[0019]
Further, as an example, it is preferable that the portable terminal further includes means for creating character data indicating a character string of the URL extracted by the extracting means and means for visually displaying the character data.
[0020]
Thereby, it is also possible to visually confirm whether or not the URL displayed in the advertisement is extracted without error and stored in the mobile terminal.
[0021]
Next, the applicant assigns a homepage with a plurality of advertisements each displaying a URL and a homepage on which the URL is displayed for each advertisement as a top page. An advertisement system including an established WWW server and the above-described portable terminal according to the present invention is proposed.
[0022]
In this advertising system, for each of a plurality of advertisements each displaying a URL, a homepage with a page on which the matter relating to the content of the advertisement is posted as a top page is set up as the homepage on which the URL is displayed in the advertisement. A WWW server is provided.
[0023]
A person who sees this advertisement and wants to browse the homepage uses the mobile terminal according to the present invention to take a picture of this advertisement with the imaging means, and accesses this WWW server based on information stored in the mobile terminal. Then, a page on which matters relating to the content of the advertisement itself are posted is first opened as a top page.
[0024]
  In this way, according to this advertising system, a home page on which a URL is displayed in an advertisement can be easily browsed simply by photographing the advertisement, and a page on which matters relating to the advertising content itself are posted. Even if you want to browse only (you do not want to browse the top page of the company or organization that is the advertiser), you can select items from the top page of the company or organization and jump to that page without the troublesome work , You can easily browse the page.
  Also, the extraction means of the mobile terminal extracts the character string representing the URL by focusing on the character string specific to the head part of the URL such as 'http: //' or 'www.' Even when characters other than the existing URL are photographed by the imaging means together with the URL, only the character string representing the URL can be extracted from those characters.
[0025]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be specifically described with reference to the drawings.
[0026]
First, a specific example of the mobile terminal according to the present invention will be described.
FIG. 1 shows an example of the appearance of a mobile phone provided with a function as a mobile terminal according to the present invention. The mobile phone 1 is a mobile phone of a type to which a CCD camera 2 with a zoom function is attached and a WWW browser is mounted. The CCD camera 2 is rotatably attached so that the lens 2a can be photographed in any direction of the front side, the upper side, and the rear side of the mobile phone 1.
[0027]
A program that executes processing as shown in FIG. 2 based on the fact that the image is taken by the CCD camera 2 is installed in the Mycoro computer that controls the entire mobile phone 1 in the mobile phone 1.
[0028]
In this process, first, an image photographed by the CCD camera 2 is stored in a memory in the mobile phone 1 (step S1).
[0029]
Subsequently, by performing character recognition from this image using a character recognition algorithm (preferably, a character to be recognized can be extracted from an image in which characters, photos, and figures are mixed), A character string of 7 characters is searched (no blank for one character or more exists between characters) (step S2). Then, it is determined whether or not this character string has been found (step S3).
[0030]
If no, the process ends. On the other hand, if the answer is yes, it is determined whether or not 'http: //', which is a character string generally used at the head of the URL, exists in the found character string (step S4). .
[0031]
If yes, characters from this image that follow the character string recognized as 'http: //' (characters before the character is cut off or before one or more blanks are left) Is recognized using a character recognition algorithm (step S5). Then, a character string in which “http: //” is added to the head of the character string recognized in step S5 is determined as a URL (step S6).
[0032]
Subsequently, character data indicating the determined URL is created (step S7), and the character data is displayed on the display of the mobile phone 1 (step S8). Also, a predetermined voice for notifying that the URL has been extracted is generated from the speaker of the mobile phone 1 (step S9).
[0033]
Subsequently, the determined URL is added to the bookmark using the bookmark function of the WWW browser (function of registering a favorite URL) (step S10). Then, the process ends.
[0034]
On the other hand, if the answer is no in step S4, whether or not there is a character string that includes 'www.', Which is a character string that is used at the beginning when the URL is abbreviated. Is recognized (step S11).
[0035]
If yes, from this image, the characters that continue after the character string recognized as this character string 'www.' (Characters before the character is cut off or before one or more blanks) Recognition is performed using a character recognition algorithm (step S12). Then, a character string in which “http: // www.” Is added to the head of the character string recognized in step S12 is determined as a URL (step S13). Then, the process proceeds to step S7 described above.
[0036]
On the other hand, if the answer is no in step S11, the process is terminated.
[0037]
The processing executed by the microcomputer other than the processing shown in FIG. 2 is the same as the processing in an existing mobile phone of the same type (with a CCD camera and a WWW browser installed).
[0038]
Further, the hardware configuration itself of the mobile phone 1 is the same as that of an existing mobile phone of the same type. (However, it is desirable that the number of pixels of the CCD camera 2 is larger than that of a CCD camera attached to an existing mobile phone in consideration of recognizing characters from an image photographed by the CCD camera 2.)
[0039]
A method of using the mobile phone 1 for browsing a home page whose URL is displayed in an advertisement is as follows.
[0040]
As shown in FIG. 3, look at the in-car advertisement (poster advertisement for hanging a train) 11 displaying the URL 11a 'http: // www. The person who uses the mobile phone 1 points the lens 2a of the CCD camera 2 to the portion of the advertisement 11 where the URL 11a is displayed, and zooms to capture the portion (shown by a broken-line frame in the figure). Shoot so that the perimeter is at the angle of view).
[0041]
Then, the process of FIG. 2 is started, and the character string “http: //” is recognized in steps S1 to S3, so that “Yes” is determined in step S4. Therefore, the character string 'www.xxx.co.jp' is recognized in step S5, and the string `http://www.xxx.co.jp 'is determined as the URL in step S6.
[0042]
Subsequently, in steps S7 to S9, as shown in FIG. 4, the character data “http: //www.○.co.jp” is displayed on the display of the mobile phone 1, and the URL extraction is completed. A voice telling that is generated from the speaker of the mobile phone 1.
[0043]
In step S 10, the URL “http: //www.○.co.jp” is added to the bookmark by the WWW browser of the mobile phone 1.
[0044]
Thereby, the homepage can be browsed by the WWW browser of the mobile phone 1.
[0045]
On the other hand, as shown in FIG. 5, a person who looks at the magazine advertisement 12 displaying the URL 12a “www. □□ .co.jp” and wants to browse the homepage uses the mobile phone 1, Point the lens 2a of the CCD camera 2 to the portion of the advertisement 12 where the URL 12a is displayed, and zoom in to shoot this portion (shoot so that the area indicated by the dashed frame in the figure is at the angle of view). .
[0046]
Then, the processing of FIG. 2 is started, and the character string “http: //” is not recognized in steps S1 to S3, but the character string “www.” Is recognized. Therefore, step S4 is no but yes in step S11. It becomes. Therefore, the character string ‘□□ .co.jp’ is recognized in step S12, and the character string ‘http: //www.□□.co.jp’ is determined as a URL in step S13.
[0047]
Subsequently, in steps S7 to S9, the character data “http: //www.□□.co.jp” is displayed on the display of the mobile phone 1 as shown in FIG. A voice telling that is generated from the speaker of the mobile phone 1.
[0048]
In step S 10, the URL “http: //www.□□.co.jp” is added to the bookmark by the WWW browser of the mobile phone 1.
[0049]
Thereby, the homepage can be browsed by the WWW browser of the mobile phone 1.
[0050]
As described above, when the mobile phone 1 is used, the homepage on which the URL is displayed in the advertisement captures the advertisement with the CCD camera 2 without performing the troublesome task of handwriting or key-ining the URL. It will be easy to browse.
[0051]
Further, since the character string representing the URL is extracted by focusing on the character string peculiar to the head part of the URL such as “http: //” or “www.”, Characters other than the URL displayed in the advertisement are extracted from the URL. When the image is taken together with the CCD camera 2 (for example, when the character “period XX” on the upper side of the URL 11a is also photographed in the advertisement 11 of FIG. 3), from among those characters, Only character strings representing URLs can be extracted.
[0052]
Further, since the character data of the extracted URL is displayed on the display of the mobile phone 1, it can be visually confirmed whether or not the URL displayed in the advertisement is extracted without error. (For example, when the URL is displayed in a small size or overlapped with a photograph or graphic being advertised, a situation may occur in which the URL is erroneously extracted because character recognition is not performed accurately. So you can check if there is such a situation.)
[0053]
Next, a specific example of the advertising system according to the present invention will be described.
FIG. 7 shows an example of a WWW server that is a component of the advertising system according to the present invention. This WWW server 21 is provided on the Internet by a company (company A) that performs a commissioned business for opening an advertisement homepage. The advertisement system described here includes the WWW server 21, advertisements exemplified later in FIGS. 8 to 11, and the mobile phone 1 of FIG. 1 described above.
[0054]
Company A entrusts the establishment of an advertising homepage from a company or organization (advertiser) that wants to perform in-car advertisements, signboard advertisements, magazine advertisements, or television advertisements.
[0055]
Then, an area (directory) dedicated to the advertisement is allocated in the WWW server 21 for each commissioned advertisement item.
[0056]
In FIG. 7, as an example, the directory ad001 is assigned to the XX Philharmonic classic concert ad commissioned from the organization B that operates the concert hall, and the directory ad002 is assigned to the television ad commission commissioned from the electrical manufacturer C. Assigned the directory ad003 to the personal computer advertising case commissioned from the same electric machine manufacturer C, and assigned the directory ad004 to the professional soccer team commissioned by the organization D operating the sports stadium XXVS It shows a state.
[0057]
The company A has these companies and organizations send an HTML document on the advertisement content itself for each advertisement item via the Internet. (Alternatively, the company A may create such an HTML document itself on behalf of a company or organization).
[0058]
The content of the HTML document may be a more detailed content posted in a car advertisement, a signboard advertisement, a magazine advertisement, a TV advertisement, or the like, or in a car advertisement, a signboard advertisement, a magazine advertisement, a TV advertisement, etc. It may be exactly the same as the content to be posted.
[0059]
That is, for example, in the case of a classic concert advertisement, when the performer, the venue, the date, and the price are posted by in-car advertisement, the content of the HTML document includes the performer, the venue, the date, the price, and the profile of the performer Or just the performer, the venue, the date and time, and the price, as in the car advertisement.
[0060]
For example, in an advertisement for an electrical product, when the appearance of an electrical product is posted in a car advertisement and the configuration and specifications of the product are simply posted, the contents of the HTML document include the appearance of the product and the configuration of the product. It may be one that publishes details or specifications, or one that publishes the appearance of the product as well as advertisements in the car and concisely publishes the configuration or specifications of the product.
[0061]
The company A puts a home page having the HTML document as a top page in a directory dedicated to the advertisement in the WWW server 21.
[0062]
That is, a home page with the top page of an HTML document about the XX Philharmonic Classic Concert transmitted from the concert hall operating organization B is placed in the directory ad001. In addition, a home page whose top page is an HTML document about a television transmitted from the electrical manufacturer C is placed in the directory ad002. Also, a home page with the top page of the HTML document for the personal computer transmitted from the electrical manufacturer C is placed in the directory ad003. In addition, a homepage having an HTML document about an advertisement item of the soccer game of XXVS □□ transmitted from the sports stadium management organization D described above as a top page is placed in the directory ad004.
[0063]
As a result, assuming that the site name of the WWW server 21 is' www.xxx.co.jp ', the URL of the homepage for advertisement of XX Philharmonic Classic Concert of Group B is' http://www.xxx.co .jp / ad001 ', and the URL of the manufacturer's C television advertising homepage is' http://www.xxx.co.jp/ad002', which is the manufacturer's personal computer advertising homepage URL. The URL is' http://www.xxx.co.jp/ad003 ', and the URL of the homepage for advertising of the soccer game of XXVS □□ of organization D is' http://www.xxx.co .jp / ad004 '.
[0064]
The company A notifies this URL to the company or organization that has commissioned the URL.
[0065]
The entrusted company or organization performs an advertisement (in-car advertisement, signboard advertisement, magazine advertisement, or television advertisement) displaying the notified URL for the commissioned advertisement item. At that time, it is assumed that the person who sees the advertisement uses the mobile phone 1 of FIG. 1 and displays the URL large and clear (more preferably, the URL overlaps or approaches other photos, figures, and characters in the advertisement). Do n’t go too far)
[0066]
FIG. 8 to FIG. 11 exemplify advertisements made through such a process. The URL 31a ‘http://www.xxx.co.jp/ad001’ is displayed in the advertisement 31 of the XX Philharmonic classic concert performed by the organization B of the concert hall (FIG. 8). The television advertisement 32 of the electrical manufacturer C displays a URL 32a of 'http://www.xxx.co.jp/ad002' (FIG. 9). A URL 33a of “http://www.xxx.co.jp/ad003” is displayed in the advertisement 33 of the personal computer of the electric manufacturer C (FIG. 10). A URL 34a of 'http://www.xxx.co.jp/ad004' is displayed in the soccer game advertisement 34 of the sports stadium management organization D (FIG. 11).
[0067]
In this advertising system, the procedure until a person who sees an advertisement browses a homepage on which a URL is displayed in the advertisement is as follows.
[0068]
A person who wants to browse the homepage by seeing the advertisements constituting the advertisement system explained the portion of the advertisement where the URL is displayed using the mobile phone 1 with reference to FIG. 3 and FIG. Shoot in the same way.
[0069]
At this time, since the URL is large and clearly displayed, it is easy to photograph the URL.
[0070]
When shooting is performed in this manner, the character data of the URL is displayed on the display of the mobile phone 1 and a voice is sent from the speaker of the mobile phone 1 to notify that the extraction of the URL is completed by the processing of FIG. This URL is added to the bookmark by the WWW browser of the mobile phone 1.
[0071]
Also in this process, since the URL displayed in a large and clear manner is photographed, the accuracy of character recognition is increased.
[0072]
When it is confirmed that the URL is extracted without error from the display on the display, the bookmarked URL is selected by the WWW browser of the mobile phone 1.
[0073]
Then, the mobile phone 1 accesses the WWW server 21 and the mobile phone 1 opens a home page.
[0074]
That is, for example, when a person who saw the advertisement 31 of the XX Philharmonic Classic Concert in FIG. 8 goes through such a procedure, the matter regarding the XX Philharmonic Classic Concert itself, which is placed in the directory ad001 of the WWW server 21, is posted. The home page (top page) is opened first.
[0075]
Further, for example, when a person who has seen the television advertisement 32 in FIG. 9 goes through such a procedure, a home page (top page) on the television itself is posted in the directory ad002 of the WWW server 21. Opened first.
[0076]
Further, for example, when a person who has seen the television advertisement 33 in FIG. 10 goes through such a procedure, a homepage (the television of the advertisement 32) on the personal computer itself placed in the directory ad003 of the WWW server 21 is placed. The same manufacturer C as John, but another top page independent of the television homepage) is opened first.
[0077]
Further, for example, when a person who saw an advertisement 34 of a soccer game XXVS □□ in FIG. 11 goes through such a procedure, the soccer XXVS □□ soccer placed in the directory ad004 of the WWW server 21 is used. The homepage (top page) that contains information about the game itself will be opened first.
[0078]
As described above, according to this advertisement system, the homepage on which the URL is displayed in the advertisement can be easily browsed simply by photographing the advertisement with the CCD camera 2 of the mobile phone 1, and the contents of the advertisement. Even if you want to browse only the pages that contain information about itself (you do not want to browse the top page of the company or organization that is the advertiser), select the item from the top page of the company or organization and jump to that page You can easily browse the page without the troublesome work.
[0079]
In the above example, as a process of extracting the URL from the advertisement, the microcomputer in the mobile phone 1 first recognizes a character string of a predetermined number of characters, and 'http: //' After searching for 'www.', it performs the process of recognizing the subsequent characters. However, as another example, first recognize all characters, and then search for a character string with 'http: //' or 'www.' At the beginning of those characters. You may make it do.
[0080]
Further, it goes without saying that the appearance of a mobile phone having a function as a mobile terminal according to the present invention may be different from that shown in FIG.
[0081]
In the above example, the mobile phone has the function as the mobile terminal according to the present invention, but the PDA (personal digital assistant) may have the function as the mobile terminal. When a PDA not equipped with a WWW browser has a function as a portable terminal according to the present invention, for example, a URL extracted from an advertisement may be stored as text data in a memory in the PDA. As a result, the text data is transferred to a terminal (personal computer or mobile phone) equipped with a WWW browser, and the homepage can be viewed on the terminal.
[0082]
In the above example, the URL of the advertisement homepage is set to 'http://www.xxx.co.jp' based on the URL of the advertisement homepage establishment trustee company A 'http://www.xxx.co.jp'. .xxx.co.jp / ad001 'to' http://www.xxx.co.jp/ad004 '. However, as another example, a URL obtained by adding ad001, ad002 and ad003, ad004 as directories to the URLs of the advertisers B, Maker C, D may be used as the URL of the homepage for advertisement.
[0083]
In the above example, an advertisement home page is opened on the WWW server 21 of the company A different from the advertiser. However, as another example, an advertisement home page may be opened on the advertiser's own WWW server without interposing such another company.
[0084]
Further, the present invention is not limited to the above examples, and it is needless to say that various other configurations can be taken without departing from the gist of the present invention.
[0085]
【The invention's effect】
As described above, according to the mobile terminal according to the present invention, the homepage on which the URL is displayed in the advertisement only needs to shoot the advertisement without performing the troublesome work of handwriting or keying in the URL. The effect of being able to browse easily is obtained.
[0086]
In addition, even when characters other than the URL displayed in the advertisement are photographed together with the URL, it is possible to extract only the character string representing the URL from those characters.
[0087]
In addition, it is possible to visually confirm whether or not the URL displayed in the advertisement is extracted without error and stored in the mobile terminal.
[0088]
  Next, according to the advertising system according to the present invention, the homepage on which the URL is displayed in the advertisement can be easily browsed simply by photographing the advertisement, and matters relating to the advertisement content itself are posted. If you want to browse only the pages that you want to view (you do not want to browse the top page of the company or organization that is the advertiser), select the item from the top page of the company or organization and jump to that page. The effect that the page can be easily browsed is obtained.
  In addition, even when characters other than the URL displayed in the advertisement are photographed together with the URL, it is possible to extract only the character string representing the URL from those characters.
