Definitions
- the present invention relates to an image reading device, a control method thereof, and a program.
- image reading device By reading an image of a document using an image reading device and generating image data of the read image, it becomes possible to electronically store image data corresponding to the image of the document or to perform information processing using the image data. Furthermore, when a document reading device equipped with an ADF (Auto Document Feeder) is used, it is possible to read images of a large number of documents more efficiently and generate image data.
- the image data of the read image obtained by the image reading process can be transferred to a terminal device (information processing device) such as a PC or mobile terminal and used for viewing or data processing.
- Patent Document 1 describes a technology in which an image reading device starts a scan process in response to a scan instruction received via a settings screen provided to the web browser, then transitions to a scanning status, and as long as that status does not change, image data can be provided via the web browser.
- a session between a terminal device, such as a mobile terminal or PC, and an image reading device is unintentionally disconnected while a scan process is being performed, the image reading device will be unable to identify (determine) the terminal device that sent the scan instruction.
- a session (connection) may be disconnected, for example, when the terminal device goes into power saving mode or the display screen of a web browser is changed to another screen. If it becomes impossible to identify the terminal device that sent the scan instruction, it may become impossible to transmit image data of the read image obtained by the scan process to the terminal device.
- the present invention provides a technology that enables an image reading device to send image data of a read image to a terminal device even if a session with the terminal device is disconnected while a reading process (scanning process) is being performed.
- An image reading device includes a management means for establishing and managing a session with a terminal device when access is received from the terminal device capable of communicating via a network, and a processing means for performing a reading process for reading an image of a document and generating image data of a read image according to a reading instruction received via the session, and the processing means continues to execute the reading process while it is receiving access via the session at a preset time interval.
- the image reading device can transmit image data of the read image to the terminal device. This reduces the possibility that image data of the read image will be lost when the session is disconnected, and improves user convenience.

- the data format included in the response sent to the terminal 200 may be, for example, the JSON format.
- the access information included in the response sent to the terminal 200 is expressed as ⁇ "IP_ADDRESS”: "192.168.0.3”, “SESSIONID”: "1”, "uniqueURL”: "http://192.168.0.2/scan/9d29d426-4cfd-4bf9-b0b7-e02b1e007c61/” ⁇ .
- the terminal management application 503 determines whether the terminal 200 (Web browser 210) has accessed the individual URL notified to the terminal 200 in S706.
- the terminal management application 503 checks whether the terminal 200 has accessed the individual URL at a predetermined time interval (e.g., every second). This time interval is generally referred to as a polling interval.
- the polling interval may be changeable by a user operation.
- the polling interval may be changed, for example, via an operation screen displayed on the operation unit 130 by the UI display application 501, or via a setting application that can be used in a terminal device such as the terminal 200.
- Setting data indicating the polling interval is stored in the storage unit 13.
- the terminal management app 503 proceeds to process from S707 to S709, and if there has been no access, the process proceeds to S708.
- the terminal management app 503 determines whether a timeout has occurred by checking that the timeout period has elapsed since the last access time from the terminal 200.
- the timeout time is set in advance, and the setting data is stored in the storage unit 13. If the last access time is not recorded, the terminal management application 503 may regard the current time as the last access time and treat it as if a timeout has not occurred.
- the timeout time generally depends on the settings of the Web server 500 when the browser session maintenance is lost, but it is desirable to set it to several minutes from the viewpoint of memory saving. In this embodiment, the timeout time is set to 30 minutes, which is longer than that.
- the timeout time may be changeable by a user operation. For example, the timeout time may be changed via an operation screen displayed on the operation unit 130 by the UI display application 501.
- the terminal management application 503 returns the process to S707, and if the timeout time has elapsed, the terminal management application 503 ends the process according to the procedure in FIG. 7.
- the terminal management application 503 causes the scan application 502 to end (cancel) the scan process and delete (discard) the image data of the scanned image stored in the storage unit 13. If an error occurs in the scan process by the scan application 502 and the error state is not resolved, the terminal management application 503 also ends the process according to the procedure in FIG. 7.
- the scan application 502 displays a message on the operation unit 130 indicating that the scan instruction has timed out, ends the scan process, and deletes the image data acquired by the scan process from the storage unit 13.
- the terminal management app 503 may display an error message on the operation unit 130, such as "An XX (jam, double feed, open cover, etc.) error has occurred.
- the scan operation has been canceled because no user operation was performed for a certain period of time. At this time, it is possible to instruct scanning once the error is resolved.”
- the terminal management app 503 may display an error message on the operation unit 130, such as "An XX (jam, double feed, open cover, etc.) error has occurred.
- the scan operation is continuing due to user operation. At this time, it is possible for the user currently scanning to obtain an image once the error is resolved.”
- the terminal management application 503 updates the last access time stored in the storage unit 13 to the current time in response to the access to the individual URL, and proceeds to S710.
- the terminal management application 503 determines whether or not a scan completion notification has been received from the scan application 502. If the terminal management application 503 has received a scan completion notification, the process proceeds to S711. On the other hand, if the terminal management application 503 has not received a scan completion notification, the terminal management application 503 communicates with the scan application 502 to obtain the current status of the scan process. Furthermore, the terminal management application 503 transmits status information indicating the status of the scan process to the terminal 200 (Web browser 210) in response to the HTTP request issued from the terminal 200 (Web browser 210) to the individual URL, and returns the process to S707.
- the terminal management app 503 sends status information indicating the error state to the terminal 200.
- the web browser 210 displays a message on the browser screen urging the user to resolve the error state, such as "An error occurred during scanning. Please resolve the error by following the display on the device screen.”
- the terminal management application 503 first notifies the terminal 200 of the completion of the scan process by a response to the HTTP request issued from the terminal 200 (Web browser 210) to the individual URL. Furthermore, in S712, the terminal management application 503 transmits HTML data (screen data) of the scan completion screen to the terminal 200 so that the terminal 200 (Web browser 210) can obtain image data of the read image obtained by the scan process, and ends the process.
- the scan completion screen includes a link for accessing an individual URL for downloading the image data, and the user of the terminal 200 can use the link to instruct the download of the image data.
- the terminal management application 503 may guide (i.e., redirect) the Web browser 210 to change the access destination from the individual URL for status acquisition to the individual URL for downloading in response to the completion of the scan process, and display the scan completion screen.
- the terminal management app 503 may release the management state of the terminal 200 using the management table in accordance with a specified condition. For example, when a scan instruction is received from a terminal device other than the terminal 200, the terminal management app 503 may delete the session ID and individual URL corresponding to the terminal 200 from the management table. Alternatively, when image data of a scanned image is acquired (downloaded) by the terminal 200, the terminal management app 503 may delete the session ID and individual URL corresponding to the terminal 200 from the management table. This allows the terminal management app 503 to release the management state of the terminal 200 using the management table at an appropriate time.
- the terminal management application 503 (CPU 11) receives access from a terminal device capable of communicating via a network, it generates a session ID of a session established with the terminal device and an individual URL unique to the session ID.
- the terminal management application 503 manages the session ID and the individual URL in association with each other.
- the scan application 502 performs a scan process (reading process) that reads an image of a document and generates image data of the read image according to a reading instruction received via the established session.
- the scan application 502 continues to execute the scan process while it is receiving access to the individual URL at a preset time interval (polling interval).
- the terminal management application 503 can identify (determine) the terminal device based on access to the individual URL.
- the terminal management application 503 accepts access to the individual URL after the scan process is completed (even after the session is disconnected), it provides the terminal device with an operation screen for obtaining image data of the read image. This makes it possible for the image reading device 100 to send image data of the read image to the terminal device even after the session is disconnected. This reduces the possibility that image data of the read image will be lost due to the session being disconnected, and improves user convenience.
- the session with the image reading device 100 may be disconnected, for example, by switching to a power saving mode or by changing the display screen of the web browser to another screen. Even in this case, as long as the session ID and individual URL associated with the IP address of the terminal device are held by the terminal management application 503, image data of the scanned image can be obtained by accessing the individual URL.
- the image reading device 100 stores the image data of the read image and controls access to the image data, but these functions may be performed by a server device (information processing device) external to the image reading device 100. In that case, the image reading device 100 transmits the image data obtained by the scan process to the server device, and the server device manages the received image data and controls access to the image data.
- a server device information processing device
- T1 ⁇ T2 30 minutes
- the above-mentioned notification may be executed by displaying a message on the operation unit 130 of the image reading device 100, or information capable of identifying the terminal 200 may be stored in the management table of FIG. 8, and notification may be executed using push notification, short-range wireless communication, or the like based on that information.
- the system may be configured to be able to reconnect when the disconnected terminal 200 attempts to access using the same session ID after the first timeout period T1 has elapsed. That is, when the terminal management application 503 receives an access from the terminal 200 using the same session ID after the first timeout period T1 has elapsed, the application may re-establish a session with the terminal 200 using that session ID. Furthermore, at that time, in order to reconnect, authentication information may be exchanged through additional processing (authentication processing of the terminal 200 may be performed). For example, the authentication information may be acquired and transmitted by reading a QR code (registered trademark) displayed on the operation unit 130 of the image reading device 100.
- QR code registered trademark
- the terminal management app 503 may be configured to be connectable by other terminal devices such as the terminal 300 after the first timeout period T1 has elapsed. That is, when the terminal management app 503 receives access from a terminal device other than the terminal 200 after the first timeout period T1 has elapsed, the terminal management app 503 may operate to establish a new session with the terminal device. At this time, the scan process that was being executed in response to a scan instruction from the terminal 200 may be finalized at that point, and the terminal 200 may be configured to only be able to download image data that has been acquired up to that point.
- the system constantly checks whether access to the individual URL has timed out during the scan process, but this is not limited to this.
- the system may be configured to start counting the time when the scan is completed, and discard the session when the timeout period has elapsed since the scan was completed. Even in this case, only terminals 200 that know the individual URL can access the image data from the scan, which improves user convenience while maintaining security.
- the image reading device 100 may be configured to perform a reconnection process involving authentication of the terminal 200 when it accepts access to an individual URL from the terminal 200 after the session with the terminal 200 has been disconnected. For example, when the image reading device 100 receives a reconnection request from the terminal 200 after the session has been disconnected, it requests the terminal 200 to transmit authentication information such as a passcode for authenticating the terminal 200. When the image reading device 100 receives the authentication information from the terminal 200, it performs authentication based on the received authentication information, and permits the terminal 200 to access the individual URL only if the authentication is successful.
- authentication information such as a passcode for authenticating the terminal 200.
- the request for authentication information to the terminal 200 may be made, for example, as follows:
- the image reading device 100 displays a two-dimensional code obtained by encoding a randomly generated passcode on the operation unit 130, and provides the terminal 200 with an operation screen that prompts the user to read the displayed two-dimensional code.
- the two-dimensional code is, for example, a QR Code (registered trademark).
- the user uses the camera function (photographing function) of the terminal 200 to read the two-dimensional code displayed on the operation unit 130.
- the terminal 200 transmits the passcode obtained by reading the two-dimensional code to the image reading device 100.
- the image reading device 100 permits the terminal 200 to access an individual URL that is managed in association with the IP address of the terminal 200. After access to the individual URL is permitted, the terminal 200 can resume the scan process or obtain (download) image data of the read image obtained by the scan process by accessing the individual URL as described above.
- the image reading device 100 may disconnect the session with the terminal 200 in response to a release request by the user of the terminal 300 to release the occupancy of the image reading device 100. For example, when the operation unit 130 is operated by another user, the image reading device 100 determines that a release request has been issued. Even if the session between the image reading device 100 and the terminal 200 is disconnected in response to the release request, the terminal 200 can resume the scan process or obtain (download) image data of the read image obtained by the scan process by accessing an individual URL, as in the above embodiment.
- the terminal 200 may be able to resume the scan process or obtain (download) image data of the read image obtained by the scan process by accessing an individual URL.
- the image reading device 100 reads an image of a document, saves the image data of the read image obtained in a predetermined storage location, and requests approval for retrieval of the image data from the storage location from an approved user (for example, a third party such as the operator user's superior).
- the storage location of the image data may be the storage unit 13 of the image reading device 100, or an external device (server device) that can communicate with the image reading device 100.
- the image reading device 100 controls access to the image data so that the image data can be retrieved from the storage location by the operating user who instructed the execution of the image reading process only when approval is obtained from the approved user.
- the configuration of the image reading device 100 in the second embodiment is the same as that in the first embodiment.
- the second embodiment may be combined with the first embodiment, that is, the image reading device 100 may be configured to perform the process of the first embodiment and the process of the second embodiment, or may be configured to perform only the process of the second embodiment.
- the approval method for performing the process of requesting the approval user for the above-mentioned approval is set in advance.

- the CPU 11 (scan application 502 running on the Web server 500) starts executing the image reading process (scanning process) according to the received reading settings and reading instructions.
- the CPU 11 controls the image reading process so that the documents set on the document tray 102 are transported one by one in sequence and the image reading unit 104 reads the images of the documents. The image reading process continues until all documents set on the document tray 102 are gone. Note that a set number of documents may be set as the reading target, or the number of documents to be read may be set in the reading settings received from the terminal 200.

- the CPU 11 (transmission determination application 503) obtains the period (determination period) to be determined for the set switching condition from the setting data stored in the storage unit 13. Then, in S1602, the CPU 11 determines whether or not to use the data size of the image data of the read image in determining the switching condition. If it is set to use the data size, the CPU 11 advances the process to S1603, and if it is set not to use the data size (to use the number of pages of the document that have been read), the CPU 11 advances the process to S1605.
- the CPU 11 calculates the total data size of the image data acquired during the determination period based on the determination period acquired in S1601 and the read image information stored in the storage unit 13 in S1404. For example, if the determination period is set to the period of one scan process, the size of the image data acquired in the most recent scan process is acquired. Next, in S1604, the CPU 11 acquires the set threshold data size (10 MB in the example of FIG. 13) as the threshold used to determine the switching condition, and proceeds to S1607.
- the CPU 11 determines whether the total data size (calculated value) corresponding to the determination period is equal to or greater than the threshold data size. If the total data size is equal to or greater than the threshold data size, the CPU 11 advances the process to S1608, determines the second destination as the destination for the image data of the scanned image, and ends the process. On the other hand, if the total data size is not equal to or greater than the threshold data size, the CPU 11 advances the process to S1609, determines the first destination as the destination for the image data of the scanned image, and ends the process.
- the size of the image data acquired in the most recent scan process is 13.5 MB

Next, in S1604, the CPU 11 acquires the set threshold document number (100 in the example of FIG. 13) as a threshold used for determining the switching condition, and proceeds to S1607.
- CPU 11 determines whether the total number of originals corresponding to the determination period (calculated value) is equal to or greater than the threshold number of originals. If the total number of originals is equal to or greater than the threshold number of originals, CPU 11 advances the process to S1608, determines the second destination as the destination of the image data of the scanned image, and ends the process. On the other hand, if the total number of originals is not equal to or greater than the threshold number of originals, CPU 11 advances the process to S1609, determines the first destination as the destination of the image data of the scanned image, and ends the process.

- the superior can check the scanned image and, if there are no problems, transfer the image data to the operating user, or, if there are problems, discard the image data without transferring it. In this way, it is possible to efficiently prevent the leakage of confidential information due to the transmission of image data of the scanned image.
- the scanned image is directly confirmed by the superior.
- the image data of the scanned image is confirmed mechanically (for example, by a specified image processing)
- by setting the switching conditions it is possible to control the image data to be sent to the superior only when a large amount of documents have been scanned. In this way, in cases where it is expected that the leakage of a large amount of confidential information will not occur, the image data will not reach the superior, and it is possible to prevent an unnecessary increase in the effort of confirming the scanned image.

When you select a favorite, scanning will start and you will be able to obtain an image.” This indicates that direct scanning can be performed by adding the screen 1900 to the favorites list of the web browser 210, and prompts the user to add this screen 1900 to the favorites list of the web browser 210. Pressing the back button 1913 returns to the scan settings screen 1710 in FIG. 17B.
- Title display section 1901 of screen 1900 displays "Color/100 dpi/A4/Double-sided/PDF.” This is the content of the HTML ⁇ title> tag.
- the URL displayed in URL display section 1902 is generated so that the part following the IP address of image reading device 100 is a unique string, starting with "favorite.”
- a download screen for obtaining the scanned image through web browser 210 is displayed. In other words, when the "Add to favorites" button 1713 in FIG.
- the image reading device 100 generates the URL shown in FIG. 19 and returns this screen 1900 when accessed for the first time from the web browser 210. Furthermore, when the image reading device 100 subsequently accesses this URL, it executes the image reading operation according to the scan settings included in this URL, but does not return screen 1900 to the web browser 210, and returns the URL of the download screen for the image read at this time to the web browser 210. Note that when accessing the URL shown in FIG. 19 for the second or subsequent times, a scanning screen (for example, a "scanning" display and the number of scanned sheets are displayed while being updated each time) may be returned to the web browser 210 until the reading operation is completed. After that, the process proceeds to S1805 in FIG. 18, and the subsequent processing may be executed.
- a scanning screen for example, a "scanning" display and the number of scanned sheets are displayed while being updated each time
- the image reading device 100 and in particular the web server 500, functions as a URL generator, but this is not limited to this and the URL may be generated by other configurations.
- the URL generation process is performed by the Web server 500.
- the Web server 500 creates a character string that lists the scan settings ("color/100dpi/A4/duplex/PDF" in the example of FIG. 19). It then arranges the login name and password, and adds the hashed character string to the end of the character string "color/100dpi/A4/duplex/PDF". The entire obtained character string is then Base64 encoded. The encoded character string is then concatenated to the URL after "favorite” to complete the character string "http://192.168.0.10/favorite/.".
- the above-mentioned steps are reversed.
- the hashed login name and password are then retrieved.
- the login name and password stored in the image reading device 100 are hashed, and an authentication check is performed using these and the hashed login name and password retrieved from the URL. If no errors are found in the authentication check, the scan settings are retrieved from the URL. If an error occurs in the authentication check, the user is notified of the error via the operation unit 130 (not shown).
- the URL may be generated without using a login name or password, or may use the time or any device information.
- the URL may contain only unique identification information, and by linking the identification information to the scan settings stored in the image reading device 100, a scan may be performed using the corresponding scan settings when the URL is accessed.
- the Web server 500 returns a response with an HTTP response code of "301" and Location in the header.
- the newly created URL is entered in Location.
- the Web browser 210 that receives the response performs a redirect by confirming the HTTP response code "301".
- the redirect destination is the URL written in the Location in the header. After that, the screen 1900 in FIG. 19 is displayed.
- the Web server 500 receives a request for the generated URL (S2001)
- the scan application 502 is launched and scanning is performed (S2004). If the scan is completed normally (No in S2005), the scanned image is sent to the Web browser 210 (S2006) and processing ends. If an error occurs during scanning (Yes in S2005), the details of the error are displayed and a screen with a scan button to enable rescanning is returned to the Web browser 210 (S2007), and processing ends.
- the user can register scan settings in the favorites of the web browser 210.
- the user simply selects a favorite registered in the web browser 210 and the image reading device 100 can start scanning and acquire an image, so there are fewer steps to start scanning and acquire an image, reducing the amount of work.
- a shortcut icon that allows direct access to a URL is placed on the desktop, for example, scanning can be started and an image can be acquired simply by clicking the icon, further reducing the amount of work.
- pressing the scan button 1711 can start scanning with the scan settings set on this screen, and pressing the "Add to favorites" button 1713 on this screen can register the scan settings to favorites.
- the scan settings can be registered to the favorites of the web browser 210 directly during normal scanning operations via the web browser 210, improving convenience.

Abstract
Description
まず、第1実施形態に係る画像読取装置(原稿搬送装置)の構成例について説明する。
図1は、本実施形態に係る画像読取装置100の概略的な構成例を示す断面図である。画像読取装置100は、読取対象の原稿101が積載される原稿台102を備える。原稿台102上の原稿は、原稿検出センサ110によって検出される。原稿台102上の原稿は、給紙ローラ106により1枚ずつ分離されて搬送路108に送り出される。搬送路108に送り出され、搬送路108を搬送される原稿101は、レジストセンサ109によって検出される。レジストセンサ109によって原稿101が検出されると、画像読取ユニット104は、搬送路108を搬送中の原稿101の画像(原稿上に形成された画像)の読み取りを開始する。
画像読取装置100において、制御部10(CPU11)は、例えば、操作部130の操作により、又は外部装置から、原稿の読み取りの開始指示(読取指示)を受けると、原稿台102にセットされた原稿101に対する画像読取処理を開始する。画像読取処理において、CPU11は、まず給紙ローラ106を駆動して、原稿台102からの原稿101の搬送を開始する。原稿台102に複数枚の原稿101がセットされた場合、1枚ずつ原稿が分離されて搬送路108を搬送される。CPU11は、その後、レジストセンサ109によって原稿101が検出されると、当該検出のタイミングを基準として、原稿101の画像の読み取りのための画像読取ユニット104の制御を行う。
図4は、本実施形態に係る画像読取システムの構成例を示す。画像読取システムは、画像読取装置100と、ネットワークを介して画像読取装置100と通信可能な端末装置(端末)200及び300とを含む。当該ネットワークは、有線LAN及び無線LAN等を含む。本実施形態では、画像読取装置100の通信I/F15は、ネットワークを介して端末200及び端末300と通信可能に接続される。なお、ネットワークは、モバイルネットワーク、インターネット、公衆無線回線等を含んでもよい。
図5は、画像読取装置100の機能構成例(ソフトウェア構成例)を示すブロック図である。画像読取装置100は、OS上で動作するアプリケーションとしてWebサーバ500を有する。画像読取装置100の起動時に、CPU11は、OSを起動し、その後にWebサーバ500を起動する。Webサーバ500は、CPU11上に常駐するプロセスとして動作し、ネットワークを介してリクエスト(要求)を受信するまで待機する。リクエストの受信に応じて、Webサーバ500は、当該リクエストに応じたレスポンス(応答)を返す。
以下で説明する手順において、画像読取処理(スキャン処理)は、端末200から画像読取装置100へ送信される読取指示(スキャン指示)に従って実行される。端末200のユーザは、端末200を操作してWebブラウザ210を起動し、Webブラウザ210によって表示されるブラウザ画面のURL入力欄に、画像読取装置100のWebサーバ500を示すURL(本実施形態では「http://192.168.0.2/」とする。)を入力する。これにより、端末200のWebブラウザ210は、画像読取装置100のWebサーバ500との通信を確立するために、Webサーバ500にアクセスする。
図7は、画像読取装置100において実行される端末判別処理の手順の例を示すフローチャートである。端末判別処理は、端末管理アプリ503によって実行される。本手順による処理は、Webサーバ500が、端末200のWebブラウザ210からスキャン設定及びスキャン指示を含むHTTPリクエストを受信し、当該HTTPリクエストを端末管理アプリ503に受け渡したことに応じて開始される。上述のように、端末判別処理は、スキャンアプリ502によるスキャン処理と並行して実行される。
第2実施形態では、画像読取装置100が、原稿の画像を読み取って得られた読取画像の画像データを所定の保存先に保存し、当該保存先からの画像データの取得についての承認を承認ユーザ(例えば、操作ユーザの上司等の第三者)に求める処理を行う例について説明する。上述のように、画像データの保存先は、画像読取装置100の記憶部13、又は画像読取装置100と通信可能な外部装置(サーバ装置)等でありうる。画像読取装置100は、承認ユーザによる承認が得られた場合に限り、画像読取処理の実行を指示した操作ユーザによる保存先からの画像データの取得が可能になるように、当該画像データに対するアクセスを制御する。なお、第2実施形態の画像読取装置100の構成は第1実施形態と同様である。第2実施形態は第1実施形態と組み合わされてもよく、即ち、画像読取装置100は、第1実施形態の処理及び第2実施形態の処理を行うように構成されてもよいし、第2実施形態の処理のみを行うように構成されてもよい。
画像読取装置100では、上述の承認を承認ユーザに求める処理を行うための承認方法の設定が予め行われる。承認方法の設定では、例えば、承認要求の送信先の設定、承認要求とともに送信するデータの内容の設定、及び承認処理に関連する設定等が行われうる。本実施形態においては、承認方法の設定は、画像読取装置100の動作設定を管理するユーザ(管理ユーザ)によって予め行われる。管理ユーザは、操作部130を用いて、画像読取装置100にログインし、画像読取装置100に対する設定操作を行うことが可能である。あるいは、後述するようにWebサーバ500を介して外部装置から設定操作される。
図10は、画像読取装置100において実行される画像読取処理の手順の例を示すフローチャートである。本例では、画像読取処理は、操作ユーザが使用する端末200から画像読取装置100へ送信される読取指示に従って実行される。
図11は、端末300において、承認ユーザの操作に従って実行される承認処理の手順の例を示すフローチャートである。
第3実施形態では、画像読取装置100が、原稿の画像を読み取って得られた読取画像の画像データの送信先を、所定の切替条件に従って決定し、当該画像データを、決定した送信先に対応する送信方法に従って当該送信先へ送信する処理を行う例について説明する。なお、第3実施形態の画像読取装置100の構成は第1実施形態と同様である。第3実施形態は第1実施形態と組み合わされてもよく、即ち、画像読取装置100は、第1実施形態の処理及び第3実施形態の処理を行うように構成されてもよいし、第3実施形態の処理のみを行うように構成されてもよい。
本実施形態において、画像読取装置100は、原稿の画像を読み取って得られた読取画像の画像データを送信するための送信方法の設定を予め行う。送信方法の設定は、画像読取装置100の動作設定を管理するユーザ(管理ユーザ)によって予め行われうる。管理ユーザは、操作部130を用いて、画像読取装置100にログインし、画像読取装置100に対する設定操作を行うことが可能である。
設定画面1300では、第一送信先に対応する送信方法として、Webブラウザ経由の送信方法、又は電子メールを用いる送信方法を選択可能である。Webブラウザ経由の送信方法は、例えば、端末200のWebブラウザ210から送信される、画像データのダウンロード用のURLにアクセスするためのリンクを用いたダウンロード指示に従って画像データを送信する方法、又は、Webブラウザ210から送信される、スキャン処理のステータスを確認するためのステータス取得要求に対する応答として画像データを送信する方法でありうる。設定画面1300では、Webブラウザ経由の送信方法について、送信に使用する通信プロトコルとして、標準のプロトコル(HTTP)を使用するか、HTTPよりセキュリティの高いプロトコルであるHTTPSを使用するかを選択可能である。また、電子メールを用いた送信方法について、送信先となる電子メールアドレスと、通信経路となるメールサーバとを設定可能である。
設定画面1300では、第二送信先に対応する送信方法として、電子メールを用いる送信方法、又はサーバ装置(データサーバ)に画像データを送信する送信方法を選択可能である。電子メールを用いた送信方法について、送信先となる電子メールアドレスと、通信経路となるメールサーバとを設定可能である。また、データサーバに画像データを送信する送信方法について、データサーバ上の画像データの保存先を示すアドレスと、送信に使用する通信プロトコル及び通信経路とを設定可能である。通信プロトコルとして、標準のプロトコル(FTP)、又はFTPよりセキュリティの高いプロトコルであるFTPSを選択可能である。通信経路として、直接データサーバへ送信する経路、又はVPN(Virtual Private Network)を用いる経路を選択可能である。
設定画面1300では更に、読取画像の画像データを送信する際の送信先の切替条件として、第一送信先から第二送信先への切り替えを行う切替条件を設定可能である。切替条件は、読取画像の画像データのデータ量が閾値データ量以上であるか否かに応じて、当該画像データの送信先を第一送信先から第二送信先に切り替えるように定められる。本実施形態では、送信先の切り替えの基準として、画像データのデータサイズ又は読み取りが行われた原稿(画像)の枚数を選択可能である。設定画面1300では、画像データのデータサイズ又は原稿の枚数を基準として送信先を切り替える切替条件について、判定対象となる期間と、閾値データサイズ又は閾値原稿枚数を設定可能である。
図14は、画像読取装置100において実行される画像読取処理の手順の例を示すフローチャートである。本例では、画像読取処理は、操作ユーザが使用する端末200から画像読取装置100へ送信される読取指示(読取開始要求)に従って実行される。
本例では、画像読取装置100(Webサーバ500)は、第二送信先への画像データの送信後に、ステータス取得要求を端末200(Webブラウザ210)から受信すると、例えば特定の文字列をステータス情報として含む応答を送信する。このステータス情報は、第二送信先(第一送信先以外の送信先)へ画像データの送信が行われたことを示す。この場合、端末200(Webブラウザ210)は、画像データが第二送信先へ送信されたことを把握し、読取設定用の設定画面600をWebブラウザ画面として表示する。あるいは、第二送信先に画像データが送信されたことを示す画面(不図示)をWebブラウザ画面として表示する。
図16は、読取画像の画像データの送信先を決定する処理(S1405)の手順の例を示すフローチャートである。
S1603で、CPU11は、S1601において取得した判定対象期間と、S1404において記憶部13に保存された読取画像情報とに基づいて、判定対象期間において取得された画像データの総データサイズを算出する。例えば、判定対象期間が1回のスキャン処理の期間に設定されている場合、直近のスキャン処理で取得された画像データのサイズが取得される。次にS1604で、CPU11は、切替条件についての判定に用いる閾値として、設定された閾値データサイズ(図13の例では、10MB)を取得し、S1607へ処理を進める。
S1605で、CPU11は、S1601において取得した判定対象期間と、S1404において記憶部13に保存された読取画像情報とに基づいて、判定対象期間においてスキャン処理が行われた原稿の総枚数(得られた読取画像の数)を算出する。次にS1604で、CPU11は、切替条件についての判定に用いる閾値として、設定された閾値原稿枚数(図13の例では、100枚)を取得し、S1607へ処理を進める。
第4実施形態では、端末200から画像読取装置100に対するスキャン設定、スキャン指示をより簡易に実現する例について説明する。なお、第4実施形態の画像読取装置100の構成は第1実施形態と同様である。第4実施形態は第1実施形態と組み合わされてもよく、即ち、画像読取装置100は、第1実施形態の処理及び第4実施形態の処理を行うように構成されてもよいし、第4実施形態の処理のみを行うように構成されてもよい。
以下、本発明の第5実施形態について説明する。なお、第4実施形態と共通の構成については同じ符号を用いるとともに説明を省略し、相違点についてのみ説明する。
