1. Field of the Invention
The present invention relates to a memo image managing apparatus, a memo image managing system and a memo image managing method, and particularly relates to a managing medium adapted to manage memo images captured from a portable terminal (information appliance) such as a portable telephone, a PHS or the like.
2. Description of the Related Art
Recently, a portable terminal such as a portable telephone, a PHS or the like equipped with capability of transmitting and receiving a digital image has become popular. Further, there are well known information appliances each comprising a built-in digital camera or an interface connectable to a compact digital camera. Such a digital camera which is embedded into or connectable to the portable terminal is useful in a variety of different scenes. In particular, it is known as its one application that the camera is used for capturing information about an environment thereof as a memo.
For example, as a first conventional art, Japanese Patent Laid-Open Publication No. HE-10-276274 describes a telephone device capable of acquiring character information from an image data by the character recognition.
Also, as a second conventional art, Japanese Patent Laid-Open Publication No. HE-05-22555 and Japanese Patent Laid-Open Publication No. HE-06-339003 respectively describe communication systems, each being capable of extracting address information such as a telephone number from an image data acquired by the character recognition function equipped in a terminal device and automatically transmitting it.
Moreover, as a third convention art, there are known Japanese Patent Laid-Open Publication No. HE-11-205515 (a communication system, a controlling method thereof and a computer-readable memory) and Japanese Patent Laid-Open Publication No. HE-10-210167 (a data registering method in a communication system, a communication system and a communication apparatus), each describing that the exchange of images between a portable telephone and a host station is enabled and character information can be extracted from an image by equipping the host station with the character recognition function.
The first conventional art as described above uses a portable terminal as a standalone, as a result of which an amount of memo images which can be stored and processed is inconveniently restrained small. Also, this portable terminal has difficulty in causing memo images which have been collected by a user to be shared more widely with the third persons. Specifically, in the event that an exchange of memo images among other users by using these portable terminals is performed, the users must communicate with one another in a one-to-one relationship for the exchange of memo images. Accordingly, it is impossible to simultaneously exchange memo images among a plurality of users, so that the exchange of memo images can not be popularized.
The second conventional art disadvantageously limits information which can be manipulated or handled by its system to the address information, and therefore can not extract and use the other information such as a title representative of a main purpose of a memo and a URL of a home page described on the memo so that registered memo images can not be effectively utilized by performing retrieval therein.
The third conventional art is not intended to manage memo images, so that, similar to that of the first conventional art, it is impossible to exchange the memo images among a plurality of users and to retrieve any memo image from a large amount of accumulated memo images. Therefore, it is hard to say the memo images thus acquired are effectively utilized among one or more users.
In order to address the above-mentioned problem and the other, the present invention has been accomplished. An object of the present invention is to provide a memo image managing apparatus, a memo image managing system and a memo image managing method which are adapted to manage a large amount of accumulated memo images and readily retrieve a predetermined memo image and information therefrom.

Hereinafter, A memo image managing apparatus, a memo image managing system and a memo image managing method of preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.
In
The character information recognizing server 3 comprises: a dictionary database (DB) 31 storing therein a recognition dictionary; a character information recognizing section 32 adapted to recognize and extract character information from a memo image by using the recognition dictionary; and a transmitting/receiving section (distribution section) 33 adapted to conduct a transmission/reception of data including the memo image to/from the managing server 2 and the portable terminal 1.
In this specification, what is meant by the term “memo image” is electronic data obtained by picking up advertisements, store signs or the like which include character information through an optical image pickup means such as a digital camera. The electronic data are image data such as JPG, PCX, GIF, TIF and BMP which can be displayed on the portable terminal. Also, the memo image may include various data such as map information, graphical data (e.g., a floor plan of real estate), photographs, and illustrations, other than the character information.
The memo image accumulating section 21 adapted to accumulate therein the memo images is storage means, such as a hard disk, a DVDRAM, a DVDR, a CD-R, a CD-RW, an MO or the like, for accumulating or rewrite electronic data, and can accumulate memo images and character information in such a manner that a certain memo image or character information thereof can be extracted through a retrieval operation as described later.
The character information recognizing section 32 is composed of a conventionally known optical character recognition software for converting image data into character information (code information) and a hardware for performing this optical character recognition. This character information recognizing section 32 holds a character recognizing dictionary of a comparatively large capacity as a recognition dictionary. Furthermore, this character information recognizing section 32 may also be configured to conduct a lattice display of the character recognition result and correct it as described later. Needless to say, the memo image accumulating section 21 and the dictionary database 31 may be provided independently of the servers 2 and 3, respectively.
The transmitting/receiving section 23 of the managing server 2 is composed of communication means such as a modem capable of distributing the retrieval result, in response to a request issued from the portable terminal 1 or the other terminal such as a non-shown computer system or L mode-capable stationary telephone set, to a predetermined terminal including another portable terminal other than the portable terminal 1 as above.
The portable terminal 1 is composed mainly of a main portable terminal unit 10 having a communication function (telephone call function), an optical image pickup means 11 such as a digital camera embedded into or connected via an interface to this main portable terminal unit 10, and a local storing section 12 embedded into or connectable to the main portable terminal unit 10 and capable of accumulating electronic data such as memo images.
The main portable terminal unit 10 is comprised of a portable telephone, a PHS, a PDA or the like which includes a non-shown telephone call section and information displaying section. The optical image pickup means 11 comprises a digital camera such as a CMOS camera or a CCD camera, a digital video camera, an image scanner, or the like. In this preferred embodiment, the optical image pickup means 11 is a digital camera embedded into or connected to the portable terminal 1.
Recently, a digital camera that is adapted to be equipped in the main portable terminal unit 10 of the portable telephone has been developed with about 77 thousand pixels as the pixel number at an initial stage of development. However, a digital camera for use in the portable terminal has just been developed with 3 hundred thousand pixels or 4.8 hundred thousand pixels. In the present invention, it is preferable to use such a digital camera 11 embedded into or connected to the portable terminal from the view point of operability, portability or acquirability of memo images.
a) through
Similarly,
The local storing section 12 is provided to temporarily accumulate memo images thus acquired or is a storing section adapted to accumulate memo images distributed from the managing server 2 as detailed later. For example, the local storing section 12 is composed of a memory embedded in the main portable terminal unit 10 or a rewritable storage device such as a memory card, e.g., a SD card, a smart media card and a compact flash card. The local storing section 12 is smaller in memory capacity than that of the memo image accumulating section 21 provided in the managing server 2.
In this embodiment, a memo image which has been acquired by the portable terminal 1 and includes text information interesting for the user will be firstly accumulated in the local storing section 12. Thereafter, the memo image will be transmitted from the potable terminal 1 to the managing server 2 (an accumulation request of the memo image: arrow 1→2 in
Also, upon the memo image transmission from the portable terminal 1 to the managing server 2, it is possible to simultaneously transmit any memo images selected from accumulation information of the memo images as shown in
A “GROUP” indicates information that only predetermined members of the group are authorized to retrieve and peruse any memo image. A “GENERAL OPEN” indicates information that anybody is authorized to retrieve and peruse any memo image without any restriction. In addition, a “PIN (Personal identification Number)” indicates information that the user is authorized to retrieve and peruse any memo image by entering a predetermined PIN (password) thereinto.
b) illustrates retrieval keyword items to be selected for retrieval of a desired memo image. This retrieval keyword is used to connect the portable terminal 1 to the managing server 2 and then retrieve the desired memo image. There are set for the retrieval keyword various categories such as hospital, educational institution, real estate and the like. For example, if the “hospital” is selected and transmitted to the managing server 2, the memo image retrieving section 22 in the managing server 2 can retrieve from the accumulated memo images memo images corresponding to a classification of the “hospital” category. In addition, the retrieval keyword items may include a memo image acquired date and hour and a memo image acquired place.
c) illustrates retrieval mode items to be selected and set for retrieval of any memo image. In the event that any accumulated memo image is retrieved, one of the selective items for retrieval mode such as “order of date and hour”, “order of place” and “order of category classification” is selected as desired and transmitted to the managing server 2 so that the managing server 2 will perform a retrieval of any memo image according to the selected and set retrieval mode.
In this way, after the memo image data has been transmitted from the portable terminal 1 to the managing server 2, the user of the portable terminal 1 can delete the memo image data thus transmitted (data relief) so as to prevent an available storage area of the local storing section 12 from being overflown. Therefore, the conventional memory overflow problem can be dissolved according to the present invention.
The managing server 2, which has received the memo image from the portable terminal 1 and has been required for accumulating it therein, registers the managed data of
The managed data (the list corresponding to memo images) as illustrated in
In the managed data as shown in
Upon or after creation of the managed data, of the memo image is processed as desired to convert its character information part from image information to text information by the character information recognizing server 3. Also, this conversion from the image information to the text information using the character information recognizing server 3 may be automatically performed by batch processing upon or after storage of the memo image into the memo image accumulating section 21 (the batch processing: an arrow 2→3 as shown in
Specifically, the managing server 2 can make a request to the character information recognizing server 3 for text information recognition with respect to respective memo images accumulated, for example, in the memo image accumulating section 21. The text recognition result acquired from thee memo image will be return from the character information recognizing server 3 to the managing server 2 and may be added to the managed data (the list corresponding memo images) as a new keyword for retrieval. Of course, the contents of the date and hours, items 1 and 2, etc. of
On the other hand, the character information recognition by the character information recognizing server 3 is able to be performed not only at a time when the memo image is accumulated but also upon a request from the portable terminal 1. In detail, the portable terminal 1 can make a request to the character information recognizing server 3 for recognition of text information included in a designated memo image (an arrow 1→3 as shown in
Thus, in this embodiment, a memo image such as a color image which is large in data amount will be able to be manipulated as character information extracted from that memo image, thereby significantly facilitating the manipulating or processing of the memo image Also, it is possible by using a character string in the text information to perform edition and retrieval in associated with the accumulated memo images. For example, it is possible from the portable terminal 1 or the other terminal (including a portable terminal of the other user or the other kind of information appliance) to perform an edition of displayed date and hour in associated with a set of the accumulated memo images and to perform a retrieval in a set of the accumulated memo images by using text information. Therefore, there is implemented a utilization circumstance of the memo images with ease of operation for a user who utilizes any memo image by using the portable terminal 1.
Further, in this embodiment, the portable terminal is not equipped with a recognition function of memo images as a stand-alone type. Instead, the memo image recognizing server is equipped with the recognition function, thereby implementing the memo image recognition with a high accuracy without any limitation imposed by a restricted operation resource of the portable terminal.
Furthermore, a user of the portable terminal 1 or the other terminal, e.g., a portable terminal possessed by the third person can make a request to the managing server 2 for retrieval of a desired memo image (an arrow 1→2 as shown in
With this configuration, it is possible to prevent the local storing section 12 from being overflown due to a great deal of memo image accumulation. Simultaneously, the memo images thus accumulated can be used commonly to a plurality of portable terminal users, thereby realizing circulation and exchange of interesting memo images.
Next, second and third embodiments of the present invention will be described with reference to
In this second embodiment as shown in
This third embodiment as shown in
In this case, upon input of the keyword “hospital” as a category for retrieval, the managing server 3 retrieves, based on the keyword, text information in association with the “hospital” from the list and then transmit it as a hospital list to the portable terminal 1 for displaying it thereon. Categories in the list corresponding to memo images can simultaneously be transmitted to the managing server 2 along with memo images to be accumulated therein as described with reference to
Next, a fourth embodiment of the present invention will be described with reference to
According to the principle as seen from this fourth embodiment, if a user employs as a retrieval keyword a memo image which has been acquired by his portable terminal 1 and illustrated on an advertising board of a predetermined store, it is possible to retrieve and list memo images in association with that store. For example, if the predetermined store is a Chinese restaurant, it is possible to perform retrieval in advertises, menu, magazine account in connection with that Chinese restaurant. Further, it is possible to acquire a list of different Chinese restaurants or to progressionally collect relevant information.
It would be appreciated that text information within a memo image cannot be perfectly recognized with the current recognition technology. Thus, it is conveniently possible to correct the recognized result such that the character information can become more accurate. Also, it is possible to efficiently obtain character information with correction of the recognized result once obtained as compared with manual typing of that character string. Although the current recognition technology is imperfect, a recognition scheme using a large amount of calculation resources is used so that a recognition error can approach zero as near as possible. As a result, there is a possibility that the character information recognition can be realized with a high accuracy.
Next, a fifth embodiment of the present invention will be described.
In this fifth embodiment, the portable terminal 1 is configured to activate usual portable telephone functions such as a call originating function and a telephone number memorizable function by using character information of a designated memo image as a parameter. In the event that a telephone number and a URL address are described in the memo image, the character information recognizing server 3 acquires their text information by performing the character recognition. Then, the recognition result is used to perform a call origination and a memory registration so that the operability of the portable terminal 1 can be improved in efficiency and simplified.
For example, it is possible to extract a telephone number from the memo image as shown in
In this sixth embodiment, the managing server 2 is configured to classify and accumulate memo images every user of a different portable terminal 1. For example, a different subset-database is created every user of a different telephone number by using the managed data (the list corresponding to memo images). With this configuration, it is possible to accumulate memo images classified every user of the different portable terminal 1 in a large scaled memo image database, thereby allowing each user to accumulate a high-capacity memo image regardless of a capacity size of the local storing section 12 of the portable terminal 1. Since a accumulation place is the large scaled memo image database that is open to public, the memo image databases of one user can be shared with the other user if there is given an authorization from the one user to the other user or can be used for perusal and retrieval in response to a request from the other user.
Next, a seventh embodiment of the present invention will be described.
In this seventh embodiment, the managing server 2 is configured to classify and accumulate its accumulated memo image information every category of memo image. For example, this can be achieved by creating a subset-database every category from the managed data as shown in
In an eighth embodiment of the present invention, the managing server 2 is configured to extract a home page information in association with a designated memo image based on character information of a URL or the like of the designated memo image by using an Internet retrieval function and to perform accumulation, exchange and presentation of an image in association with the home page information as a memo image.
For example, from the memo image of an advertisement observed inside of a train, a URL of a home page of an object which is advertised by the advertisement is extracted as text information. Then, the home page specified by the URL is accessed via the Internet to accumulate its content as a memo image. Otherwise, the content is used as a retrieval keyword to perform the retrieval in the large scaled memo image database so that a set of memo images in association with the train advertisement as a first memo image are extracted for presentation thereof to a user. According to the principle as seen from this eight embodiment, it is possible for the user to rapidly and readily acquire a set of memo images in association with a certain memo image.
In this ninth embodiment, the character information recognizing server 3 is configured to extract from a designated memo image not only character information but also table information and photograph information such as rules and cells within graphic information and a table. This retrieval processing is performed, for example, by using pattern matching in a technical field of image processing or similarity retrieval in a technical field of computers.
According to the principle as seen from this ninth embodiment, it is possible to extract graphic information and photograph information included in a memo image obtained from a document having a complicated layout such as a magazine or newspaper and picked up by a digital camera, so that structure information within the graph, various information within a table and the photograph can be reused while any retrieval can be performed with those clues to go on.
In this tenth embodiment, the character information recognizing server 3 is configured to binarize a designated memo image (a color image or gray scale image) at a high quality or convert the designated memo image into a thumbnail file to compress it for transmission thereof to the managing server 2.
According to the principle of this tenth embodiment, it is possible to convert the color/gray scale memo image of large capacity into the binarized monochrome image of small capacity. That is, it is possible due to binarization technology to decrease a capacity of the color/gray scale memo image to obtain the monochrome memo image of small capacity with available information such as text information, graphic information, table information and photograph information remained therein, thereby implementing exchange and accumulation of such small capacity memo images. Also, it is possible to decrease a capacity of the database and improve an exchange speed of memo image.
Similarly, it is possible to decrease a size of the color images by forming their thumbnail files and then display a plurality of their memo images on a display screen of the portable terminal 1 as shown in
In this eleventh embodiment as shown in
Specifically, the character candidate lattice means data having a lattice structure including character segmentation candidates and character recognition result candidates of text information which has been obtained by recognizing the text information within the memo image by the character information recognizing section 32.
According to the principle of this eleventh embodiment, even if the recognition result of text information within the memo image includes some errors, the possibility that correct answers are included in the character candidate lattice is high. Therefore, the user can acquire the retrieval result with a high precision by using the character candidate lattice, thereby advantageously improving a retrieval precision of a desired memo image.
In this way, the present invention provides the user with an ease-of-use memo image utilization function because a large amount of memo images can be exchanged and managed independently of processing limit of the portable terminal 1. Also, it is possible to realize the memo image utilization function with a higher performance and functionality by upgrading the version of the memo image managing apparatus or the character information recognizing section without any financial burden on the portable terminal user. Furthermore, it is possible to smoothly exchange any memo image among plural users, thereby advantageously overcoming conventional problems.
Next, as a twelfth embodiment, the memo image managing apparatus and an operation of the memo image managing system, i.e., the memo image managing method according to the present invention will be described.
In
To the contrary, the user can retrieve one of the memo images registered in the managing server as described above by using his portable terminal (including a personal computer or a PDA) and acquire the desired memo image. In this case, as shown in
In addition, the memo images accumulated in the managing server are each converted into character information for serving as a retrieval keyword according to the flow chart as shown in
In the case that the managing server executes a series of steps of S21 through S23, this can be automatically executed by using a batch system. Also, in the case that the portable terminal executes this series of steps, the character information recognizing server is employed to create a character recognition candidate lattice based on the recognition result of the character information converted from the memo image. In this case, the flow chart as shown in
In each of the memo image managing apparatuses of the embodiments as described above, it is possible to accumulate a large amount of memo images obtained by a portable terminal such as a portable telephone, a PHS or the like and to retrieve and acquire a required memo image from the accumulated memo images as desired by using an information appliance such as the portable terminal, a computer, or the like.
Also, if the memo image managing apparatus is configured in such a manner that the memo images are classified and managed every user, e.g., by using telephone number of the user's portable telephone, a call originator of any memo image can be readily revealed and identified in the event that memo image information is shared among a plurality of users.
Also, if the memo image managing apparatus is configured in such manner that any memo image is classified and managed based on character information extracted from the memo image, the retrieval keyword can automatically be obtained from the memo image as a result of which its management can be readily and rapidly performed.
Further, if the memo image managing apparatus is equipped with an internet retrieval function section adapted to access a home page based on character information in a predetermined memo image and extract information of that home page, a user will be able to readily acquire various information in association with a memo image.
While preferred exemplary embodiments of the present invention have been described above, it is to be understood that further adaptations of the invention described herein can be obtained by appropriate modifications by one of ordinary skill in the art without departing from the scope of the present invention. Accordingly, although preferred configurations of apparatuses, systems, and methods embodying the present invention have been described, it should be understood that these apparatuses, systems, and methods may take on a wide variety of configurations and arrangements without departing from the scope of the present invention.
