Patent Application
20150146236
This application is based upon, and claims the benefit of priority from, corresponding Japanese Patent Application No. 2013-245142 filed in the Japan Patent Office on Nov. 27, 2013, the entire contents of which are incorporated herein by reference.
Unless otherwise indicated herein, the description in this section is not prior art to the claims in this application and is not admitted to be prior art by inclusion in this section.
An image forming apparatus, such as a multifunction peripheral, has a function to read a document with a scanner and to convert the scanned data into image data. Thus, the image forming apparatus can easily convert the read document into image data. Accordingly, even if the document contains confidential information, a user can copy the image data on the document to a paper sheet, store the image data in an external memory, or transmit the image data to another apparatus. In view of this, a leakage of the image data on the document describing the confidential information is prevented as follows. The image forming apparatus or a management server, which is connected to the image forming apparatus over a network, stores the image data on all the read documents as an image-log. It is confirmed whether or not the stored image data contains the confidential information. Additionally, the user is notified that the read image data on the read document is under surveillance. However, to store the image data on the all read documents, the image forming apparatus and the management server require a storage device such as a large-capacity hard disk. In view of this, a measure to save the storage capacity for the image data has been taken. For example, when a page of a blank sheet document is detected, a known image processing apparatus can select any of the following processes to ensure saving the storage capacity for the image data.
An image forming apparatus according to one aspect of the disclosure includes an image-log creation unit, a document blank sheet page skip scan function setting unit, a blank sheet page image registration setting unit, and a blank sheet page image image-log output setting unit. The image-log creation unit creates an image of an image-log from image attribute information and image data of a read document. The document blank sheet page skip scan function setting unit sets whether to use a skip scan function of a blank sheet page of a document. The blank sheet page image registration setting unit sets whether to register a blank sheet page image of the document. The blank sheet page image image-log output setting unit sets whether to output an image-log of the blank sheet page images.
These as well as other aspects, advantages, and alternatives will become apparent to those of ordinary skill in the art by reading the following detailed description with reference where appropriate to the accompanying drawings. Further, it should be understood that the description provided in this summary section and elsewhere in this document is intended to illustrate the claimed subject matter by way of example and not by way of limitation.
Example apparatuses are described herein. Other example embodiments or features may further be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. In the following detailed description, reference is made to the accompanying drawings, which form a part thereof.
The example embodiments described herein are not meant to be limiting. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the drawings, can be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are explicitly contemplated herein.
The following describes an embodiment of the disclosure with reference to the drawings.
The following describes a functional configuration of an image forming apparatus 100 according to the embodiment with reference to
The control unit 101 includes a main storage unit such as a RAM and a ROM and a Micro Processing Unit (MPU) and a Central Processing Unit (CPU). The control unit 101 controls the overall image forming apparatus 100 including various I/Os, an interface such as a Universal Serial Bus (USB), a bus controller, and a similar device. The control unit 101 includes the image registration storage processor 101a and the image-log creation storage processor 101b. The image registration storage processor 101a stores image attribute information and image data created by reading a document (hereinafter referred to as “scan”) in the image document box 102a. The image-log creation storage processor 101b creates an image-log from the image attribute information and the image data and stores the image-log to the image-log storage area 103a. To the image attribute information, information such as an image quality, a resolution, a size, a rotation direction, and a color of the image data, a presence of a blank sheet page, and a page position (for example, the page number) of the blank sheet page is set if the blank sheet page is present. Details of the image registration storage processor 101a and the image-log creation storage processor 101b will be described later.
The auxiliary storage unit 102 is a flash memory where a program and data for a process performed by the control unit 101 are stored. The image registration storage processor 101a stores the image attribute information and the image data to the image document box 102a. A directory structure of the image document box 102a will be described later.
The storage unit 103 is a storage device, such as a hard disk drive, that stores data and a program. The image-log creation storage processor 101b stores the image data as the image-log in the image-log storage area 103a.
The operation panel 104 accepts an operation and a setting by an administrator or a user. The operation panel 104 displays an operation item of a function and a screen of the setting item of the image forming apparatus 100 and a message to be notified to the administrator or the user.
The operation panel processor 105 performs: a process that displays the screen of the operation item of the function of the image forming apparatus 100 on the operation panel 104, a process that inputs an operation and a setting by the administrator or the user input from the operation panel 104, and a process that displays a message to notify the administrator or the user of a state of the image forming apparatus 100 on the operation panel 104.
The scanner unit 106 scans a document set on a document platen of the image forming apparatus 100 to digitalize the document. Inputting a scan request causes the scanner unit 106 to scan the document on the document platen. The scanner unit 106 outputs data where the document is digitalized (hereinafter referred to as “digital data”) to the image processor 107. When a scan setting including the blank sheet page (without a skip scan function) is configured, the scanner unit 106 leaves the blank sheet page of the document as the image data. When the scan setting excluding the blank sheet page (with the skip scan function) is configured, the scanner unit 106 does not leave the blank sheet page of the document as the image data.
When inputting an image creation request, the image processor 107 inputs the digital data of the document from the scanner unit 106. The image processor 107 creates the image attribute information from the digital data. Additionally, the image processor 107 converts the text information of the digital data into bitmap graphics (data in raster format) to create imaged (rasterized) image data of the document. When a setting to register a blank sheet page image is configured and the image processor 107 detects the blank sheet page, the image processor 107 registers information on the blank sheet page image with the image attribute information and registers the blank sheet page image with the image data. When the setting not to register the blank sheet page image is configured and the image processor 107 detects the blank sheet page, the image processor 107 registers the information on the blank sheet page image with the image attribute information but does not register the blank sheet page image with the image data.
When inputting a print request from the user from the operation panel processor 105, the image printing unit 108 prints the image data on the document with the image attribute information and the image data of the document, which are stored in the image document box 102a, to a paper sheet.
The network communication unit 109 includes an attachable/removable LAN interface for connection to a network 200. The LAN interface includes a network unit that performs intelligent transmission and reception in various network protocols, such as TCP/IP, AppleTalk, and SMB.
The following describes a directory structure of the image document box 102a with reference to
The following describes settings and processes until a blank sheet page image, which is created through scanning the blank sheet page of the document, is output to the image-log using
“The document blank sheet page scan setting” k1 is a setting item of whether to leave the blank sheet page of the document as the image data or not when the blank sheet page is detected. To leave the blank sheet page of the document as the image data, “without skip scan function” is set, while not to leave the blank sheet page of the document as the image data, “with skip scan function” is set. The “blank sheet page image registration setting” k2 is a setting item of whether to register the blank sheet page image or not. To register the blank sheet page image, “with registration” is set, while not to register the blank sheet page image, “without registration” is set. When “with scan” is set to “the document blank sheet page scan setting” k1 and “with registration” is set to “the blank sheet page image registration setting” k2, upon detection of the blank sheet page image from the image on the scanned document, the “blank sheet page image registration process” k3 registers the blank sheet page image with the image attribute information and the image data. When “without skip scan function” is set to “the document blank sheet page scan setting” k1 and “without registration” is set to “the blank sheet page image registration setting” k2, upon detection of the blank sheet page image from the image on the scanned document, “the blank sheet page image registration process” k3 registers the blank sheet page image with the image attribute information but does not register the blank sheet page image with the image data. When “with skip scan function” is set to “the document blank sheet page scan setting” k1, since the blank sheet page of the document is not left as the image data, “the blank sheet page image registration process” k3 does not register the blank sheet page image with the image attribute information and the image data.
“The blank sheet page image image-log output setting” k4 is a setting item of whether or not to output the blank sheet page image to the image-log. To output the blank sheet page image to the image-log, “with output” is set, while not to output the blank sheet page image to the image-log, “without output” is set. Assume the case where “without skip scan function” is set to “the document blank sheet page scan setting” k1 and “with registration” is set to “the blank sheet page image registration setting” k2. When “with output” is set to “the blank sheet page image image-log output setting” k4, “the blank sheet page image image-log output process” k5 outputs an image including the blank sheet page image scanned from the document as the image-log. When “without output” is set to “the blank sheet page image image-log output setting” k4, “the blank sheet page image image-log output process” k5 outputs an image excluding the blank sheet page image as the image-log.
Assume the case where “without skip scan function” is set to “the document blank sheet page scan setting” k1 and “without registration” is set to “the blank sheet page image registration setting” k2. If “with output” is set to “the blank sheet page image image-log output setting” k4, “the blank sheet page image image-log output process” k5 outputs the image including the blank sheet page image created from the image attribute information as the image-log. If “without output” is set to “the blank sheet page image image-log output setting” k4, “the blank sheet page image image-log output process” k5 outputs the image excluding the blank sheet page image as the image-log. When “with skip scan function” is set to “the document blank sheet page scan setting” k1, since the blank sheet page of the document is not left as the image data, “the blank sheet page image image-log output process” k5 does not output the blank sheet page image as the image-log.
The following describes an image registration storage process performed by the image registration storage processor 101a of the image forming apparatus 100 according to the embodiment of the disclosure with reference to
First, the image registration storage processor 101a inputs the user ID, which is set from the operation panel 104, from the operation panel processor 105.
Next, when inputting “the document blank sheet page scan setting” k1, which is set from the operation panel 104, from the operation panel processor 105, the image registration storage processor 101a determines whether either of “without skip scan function” or “with skip scan function” is set. When “without skip scan function” is set (Yes at Step S102), the process proceeds to Step S103. When “with skip scan function” is set (No at Step S102), the process proceeds to Step S107.
At Yes at Step S102, when the image registration storage processor 101a outputs a scan request of a scan setting including the blank sheet page of the document to the scanner unit 106, the scanner unit 106 outputs the digital data of the document created through scanning including the blank sheet page of the document set to the document platen to the image processor 107.
Next, when inputting “the blank sheet page image registration setting” k2, which is set from the operation panel 104, from the operation panel processor 105, the image registration storage processor 101a determines whether either of “with registration” or “without registration” is set. When “with registration” is set (Yes at Step S104), the process proceeds to Step S105. When “without registration” is set (No at Step S104), the process proceeds to Step S106.
At Yes at Step S104, when the image registration storage processor 101a outputs the image creation request with a setting to register the blank sheet page image to the image processor 107, the image processor 107 inputs the digital data of the document from the scanner unit 106. Next, upon detection of the blank sheet page from the digital data of the document, the image registration storage processor 101a creates the image attribute information where the blank sheet page image information is registered and the image data where the blank sheet page image is registered. Then, the process proceeds to Step S109.
At No at Step S104, when the image registration storage processor 101a outputs a request not to register the blank sheet page image to the image processor 107, the image processor 107 inputs the digital data of the document from the scanner unit 106. Next, upon detection of the blank sheet page from the digital data of the document, the image registration storage processor 101a creates the image attribute information where the blank sheet page image information is registered and creates the image data where the blank sheet page image is not registered. Then, the process proceeds to Step S109.
At No at Step S102, the image registration storage processor 101a outputs the scan request with the scan setting excluding the blank sheet page of the document to the scanner unit 106. Then, the scanner unit 106 outputs the digital data of the document, which is created through scanning excluding the blank sheet page of the document set on the document platen, to the image processor 107.
Next, the image registration storage processor 101a outputs the image creation request to the image processor 107. The image processor 107 inputs the digital data of the document from the scanner unit 106. Thus, the image processor 107 creates the image attribute information and the image data.
Next, the image registration storage processor 101a creates a file with a name formed of the user ID, which is input at Step S101, and a current date and time in the original image attribute information directory 102a1.
Next, the image registration storage processor 101a stores the image attribute information, which is created at Step S105, Step S106, or Step S108, in the file of the original image attribute information directory 102a1. The file of the original image attribute information directory 102a1 is created at Step S109.
Next, the image registration storage processor 101a creates a file with a name formed of the user ID, which is input at Step S101, and the current date and time in the original image data directory 102a2.
Next, the image registration storage processor 101a stores the image data, which is created at Step S105, Step S106, or Step S108, into the file, which is created at Step S111, in the original image data directory 102a2.
Next, the image registration storage processor 101a starts the image-log creation storage processor 101b and terminates the image registration storage process.
The following describes an image-log creation process performed by the image-log creation storage processor 101b of the image forming apparatus 100 according to the embodiment of the disclosure with reference to
First, the image-log creation storage processor 101b inputs the user ID, which is set from the operation panel 104, from the operation panel processor 105.
Next, when “the document blank sheet page scan setting” k1, which is set from the operation panel 104, is input from the operation panel processor 105, the image-log creation storage processor 101b determines either of whether “without skip scan function” or “with skip scan function” is set. When “without skip scan function” is set (Yes at Step S202), the process proceeds to Step S203. When “with skip scan function” is set, (No at Step 202), the process proceeds to Step S210.
At Yes at Step S202, when inputting “the blank sheet page image registration setting” k2, which is set from the operation panel 104, from the operation panel processor 105, the image-log creation storage processor 101b determines whether either of “with registration” or “without registration” is set. When “with registration” is set (Yes at Step S203), the process proceeds to Step S204. When “without registration” is set (No at Step S203), the process proceeds to Step S207.
At Yes at Step S203, when inputting “the blank sheet page image image-log output setting” k4, which is set from the operation panel 104, from the operation panel processor 105, the image-log creation storage processor 101b determines whether either of “with output” or “without output” is set. When “with output” is set (Yes at Step S204), the process proceeds to Step S205. When “without output” is set (No at Step S204), the process proceeds to Step S206.
At Yes at Step S204, the image-log creation storage processor 101b creates the image-log of the images where the blank sheet page image scanned from the document is left as the image data. Then, the process proceeds to Step S211.
At No at Step S204, the image-log creation storage processor 101b creates the image-log of the images excluding the blank sheet page image scanned from the document. Then, the process proceeds to Step S211.
At No at Step S203, when inputting “the blank sheet page image image-log output setting” k4, which is set from the operation panel 104, from the operation panel processor 105, the image-log creation storage processor 101b determines whether either of “with output” or “without output” is set. When “with output” is set (Yes at Step S207), the process proceeds to Step S208. When “without output is set (No at Step S207), the process proceeds to Step S209.
At Yes at Step S207, the image-log creation storage processor 101b creates the image-log of the images including the blank sheet page image, which is created from the image attribute information. Then, the process proceeds to Step S211.
At No at Step S207, the image-log creation storage processor 101b creates the image-log of the images excluding the blank sheet page image. Then, the process proceeds to Step S211.
At No at Step S202, the image-log creation storage processor 101b creates an image where the blank sheet page image is not left as the image data as the image-log. Then, the process proceeds to Step S211.
Next, the image registration storage processor 101a creates a file with the name formed of the user ID, which is input at Step S201, and the current date and time in the image-log storage area 103a.
Next, the image registration storage processor 101a stores the image-log, which is created at Step S205, Step S206, Step S208, Step S209, or Step S210, into the file, which is created at Step S211, in the image-log storage area 103a. Then, the image registration storage process is terminated.
As described above, only when the administrator has configured the setting to scan the blank sheet page of a document, the blank sheet page is scanned. Accordingly, when a setting not to perform scanning is configured, the blank sheet page is not scanned. The blank sheet page image is not registered with the image attribute information and the image data. This ensures saving a storage capacity. Assume the case where the administrator has configured the setting to scan the blank sheet page of the document. When a setting to register the blank sheet page image is configured, the blank sheet page image is registered with the image attribute information and the image data. When a setting not to register the blank sheet page image is configured, the blank sheet page image is not registered with the image data. This ensures saving the storage capacity.
Assume the case where the administrator has configured the setting to scan the blank sheet page of the document, the setting to register the blank sheet page image, and the setting to perform a blank sheet page image image-log output. This outputs the blank sheet page image of the scanned blank sheet page. Accordingly, the administrator can exactly confirm the number of blank sheet pages of the document. The administrator can also confirm whether the document regarded as the blank sheet page conceals confidential information or not. Further, when the setting not to perform the blank sheet page image image-log output is configured, the blank sheet page image of the scanned blank sheet page is not output. However, as necessary, the image-log of the images including the blank sheet page image of the scanned blank sheet page can be output.
Assume the case where the administrator has configured the setting to scan the blank sheet page of the document, the setting not to register the blank sheet page image, and the setting to perform the blank sheet page image image-log output. The blank sheet page image is created from the image attribute information and is output. Accordingly, the administrator can exactly confirm the number of blank sheet pages of the document. Further, when the setting not to perform the blank sheet page image image-log output is configured, the blank sheet page image is not created from the image attribute information and therefore is not output. However, as necessary, the image-log of the images including the blank sheet page image, which is created from the image attribute information, can be output.
The file in the image-log storage area 103a, which stores the image-log, is named formed of the user ID and the current date and time. Accordingly, when detecting the confidential information from the image-log, the user can be easily confirmed from the user ID. Additionally, the date and time when the image-log is created can be easily confirmed from the current date and time. Further, the file in the image document box 102a, which stores the image attribute information and the image data, is named formed of the user ID and the current date and time. This ensures easily determining the image attribute information and the image data corresponding to the image of the image-log.
In the embodiment, the image-log storage area 103a in the storage unit 103 of the image forming apparatus 100 stores the image-log of the images. This, however, should not be construed in a limiting sense. The image-log of the images can be transmitted to the management server or a file server (hereinafter referred to as an “external server”) connected to the network 200, and an image-log storage area, which is arranged at the storage device such as a hard disk drive in the external server, can store the image-log of the images. Thus, transmitting the image-log of the images to the external server eliminates the need for arranging the image-log storage area 103a in the image forming apparatus 100. Setting “without registration” to the setting item of “the blank sheet page image registration setting” k2 does not cause the image data of the blank sheet page image to be stored in the image document box 102a. This further ensures saving the storage capacity.
The image attribute information, the image data, and the image-log are stored in the file with the name formed of the user ID and the current date and time. However, this should not be construed in a limiting sense. The user ID and the current date and time can be added to the beginning or the end of the image attribute information, the image data, and the image-log, and then the image attribute information, image data, and the image-log can be stored in the file.
When the user performs the scan request of the document, the user inputs the user ID from the operation panel 104 in the above-described embodiment. However, when the user further inputs a password, scanning of the document containing the confidential information by impersonation of the user of the user ID can be prevented.
The image forming apparatus and the image processing system of the disclosure can facilitate: the saving of the storage capacity of the image-log, confirmation of the number of pages of the blank sheet document by the image-log, and/or confirmation whether the blank sheet document conceals the confidential information or not.
The disclosure is described above with the specific embodiments; however, the above-described embodiments are examples of the disclosure, and it is needless to say that the disclosure is not limited to the embodiments.
The disclosure is preferable for an image forming apparatus and an image processing system; however, this should not be limited to the image forming apparatus and the image processing system. The disclosure is applicable to general apparatuses and systems that can store image data.
While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
