Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an image reading and transmitting apparatus, an image checking data generating method, and a program for controlling the method, and more particularly to an image reading and transmitting apparatus provided with functions for reading images and transmitting the images to other devices or apparatuses, such as a copier, a fax, a scanner, an image checking data generating method applied to the image reading and transmitting apparatus, and a program for causing a computer to execute the image checking data generating method.

2. Description of the Related Art

Conventional image reading and transmitting apparatuses that read images and transmit the read images to other devices or apparatuses are adapted to permit checking the read image before transmitting if it is desired to do so. A first prior art apparatus carries out conversion processing on the read image data such as resolution conversion, image layout conversion, color conversion, in order to tailor the read image to the capabilities of a display, such as resolution, image layout, color reproducibility, and then transfers the converted image data to the display, to thereby permit checking (e.g. Japanese Laid-Open Patent Publication (Kokai) No. H03-245677).

Furthermore, a second prior art apparatus carries out reading an image twice, to generate an image suited to the capabilities of a display by the first reading, and generate image data for transmission by the second reading (e.g. Japanese Laid-Open Patent Publication (Kokai) No. H09-102846).

Also in the case where the read image data is transmitted to a storage device and stored therein, the first prior art apparatus is applied to display the stored image data for checking at a later time.

However, as stated above, to generate image checking data with the first prior art apparatus based on the image data stored in the storage device, the time-consuming image conversion processing is involved at the time of checking, thus requiring an undesired waiting time before the user checks the image checking data. Thus, there is a desire to eliminate the waiting time.

In the second prior art apparatus as well, the time-consuming reading processing must be performed twice before the read image data is transmitted to another device or apparatus after checking, thus entailing a long time period before the transmission processing is complete.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will now be described in detail with reference to the drawings showing preferred embodiments thereof.

FIG. 1 is a block diagram showing the configuration of a network system including an image reading and transmitting apparatus according to a first embodiment of the present invention.

The network system is comprised of an image reading and transmitting apparatus 1 and a database server 2 which are interconnected via a network 3.

The image reading and transmitting apparatus 1 is a multi-function apparatus having a copy function and a facsimile function and is mainly comprised of a central processing unit (CPU) 101, a main storage device 102, a display 103, an input device 104, an external storage device 105, a printer 106, an image reader 107, and a network unit 108.

The CPU 101 controls the main storage device 102, the display 103, the input device 104, the external storage device 105, the printer 106, the image reader 107, and the network unit 108, and also performs arithmetical and logical operations.

The main storage device 102 stores information necessary for the image reading and transmitting apparatus 1 to perform information processing. The stored information is read whenever necessary.

The display 103 displays graphics, characters, etc. resulting from the information processing performed by the apparatus 1, and is implemented by a touch panel display.

The input device 104 inputs various signals to the CPU 101, and includes a keyboard and a touch panel.

The external storage device 105 stores various information, and is implemented by a magnetic storage device, a magneto-optical storage device or the like. This external storage device 105 stores image data read by the image reader 107.

The database server 2 is mainly comprised of a CPU 201, a network unit 202, and an external storage device 203. The database server 2 stores and manages groups of image page data as documents, and stores and manages image checking display data corresponding to image page data of each document. According to a request to retrieve a document from one of client terminals, including the image reading and transmitting apparatus 1, which are connected to the network 3, either image page data or image checking display data is downloaded for the client terminal.

The image reading and transmitting apparatus 1 connected to the database server 2 via the network 3 can register a group of image page data read by the apparatus 1, in the database server 2 as a document.

The network 3 includes Ethernet (registered trademark) USB (Universal Serial Bus). The image reading and transmitting apparatus 1 and the database server 2 may be connected to each other through serial connection or parallel connection.

Displayed on the display 103 of the image reading and transmitting apparatus 1 is an instruction input screen through which an operator gives instructions to read, display for checking, store, and transmit images.

FIG. 2 is a view showing the instruction input screen displayed on the display 103 of the image reading and transmitting apparatus 1. The display 103 is implemented by a touch panel display, as mentioned above.

When a preview instruction button 201 is pressed on the instruction input screen, image display is carried out which enables the operator to view and check an image already read. An address input field 205 displays a string of characters entered via the input device 104. When any of address type selection buttons 204 is pressed, the character string entered and displayed in the address input field 205 is additionally displayed in an address field 202 as an address of the type indicated by the button pressed. An address “email@mail.co.jp” displayed as an example in the address field 202 is the electronic mail address of a destination set by pressing a button “email”. Similarly, an address “ftp.co.jp” is the MAC address of the database server 2 set by pressing a button “DB”, and an address “03-3333-3333” is the fax number of a destination set by pressing a button “FAX” (a button “BOX” will be described later).

When a scan/send start button 203 is pressed, the image reader 107 carries out scanning an image. The scanned image data is stored in the external storage device 105, and the stored image data is transmitted to an address indicated in the address field 202. Note that the image checking display data is generated based on the image data, and stored, as necessary, details of which will be described later with reference to FIGS. 4A and 4B.

The external storage device 105 of the image reading and transmitting apparatus 1 includes a temporary image data storage area, and a plurality of Box storage areas. Each of the Box storage areas has an identifier “Box+a number” assigned thereto. By entering such an identifier to the address input field 205 and then pressing the button “BOX”, which is one of the address type selection buttons 204, the identifier is set in the address field 202 to indicate as an address a corresponding one of the Box storage areas in the external storage device 105. An address “Box01” shown as an example in the address field 202 is the identifier of one of the Box storage areas in the external storage device 105.

In each Box storage area of the external storage device 105, image data read by the image reader 107, and image checking display data generated based on the read image data are stored. The image checking display data can be viewed on the display 103 at any time until it is deleted in response to an instruction from the operator. Similarly, the image data can be printed by the printer 106 at any time until it is deleted in response to an instruction from the operator.

FIG. 3 is a flowchart showing a procedure for reading an image and generating image checking display data executed by the image reading and transmitting apparatus 1.

In a step S301, it is determined whether or not an instruction has been inputted to read an image. If the instruction has been inputted, the process proceeds to a step S302, and if the instruction has not been inputted, the process repeats the step S301.

In the step S302, the image reader 107 reads one page of image data. Then, in a step S303, it is determined whether or not an instruction has been given to generate image checking display data (which will be described later with reference to FIGS. 4A and 4B). If the instruction has been given, the process proceeds to a step S304, and if the instruction has not been given, the process skips over the step S304 to a step S305. In the step S304, image checking display data is generated based on the page of the image read in the step S302. That is, a set of conversion processes is performed, which involves resolution conversion, image layout conversion, color conversion, etc. in order to tailor the read image to the capabilities of the display 103.

In the step S305, it is determined whether or not the image reader 107 has read image data up to the last page. If the image reader 107 has not read image data up to the last page, the process returns to the step S302 to read the remaining page or pages. If the image reader 107 has read image data up to the last page, the process is terminated.

FIGS. 4A and 4B are flowchart showing a procedure for reading, checking, storing, and transmitting an image executed by the image reading and transmitting apparatus 1 according to instructions inputted to the instruction input screen.

In a step S401, it is determined whether or not the scan/send start button 203 on the instruction input screen of FIG. 2 has been pressed. If the button 203 has been pressed, the process proceeds to a step S402. If the button 203 has not been pressed, the process returns to the step S401 to wait until the button 203 is pressed.

Next, in the step S402, it is determined whether or not the preview instruction button 201 of FIG. 2 has been pressed. If the button 201 has been pressed, the process proceeds to a step S408. If the button 201 has not been pressed, the process proceeds to a step S403, where it is determined whether or not the identifier of a Box storage area in the external storage device 105 is contained in the address field 202. If the identifier is contained, the process proceeds to a step S406, and if the identifier is not contained, the process proceeds to a step S404.

In the step S404, the process shown in FIG. 3 is performed on the assumption that no instruction has been inputted to generate image checking display data (NO to the step S303), whereby only image data for transmission is generated, and then, in a step S405, the image data for transmission generated in the step S404 is stored in the temporary image data storage area of the external storage device 105.

In the step S406, the process shown in FIG. 3 is performed on the assumption that an instruction has been inputted to generate image checking display data (YES to the step S303), whereby both image data for transmission and its image checking display data are generated. And then, in a step S407, the image data for transmission is stored, along with the image checking display data, in the Box storage area of the external storage device 105 to which is assigned the identifier inputted in the address field 202. By thus storing, in the step S407, the image data for transmission in the Box storage area of the device 105 together with its image checking display data, the operator can read the image data for transmission and the image checking display data from the Box storage area of the external storage device 105 for transmitting the image data for transmission to different addresses and checking or previewing the image through the image checking display data as many times as the operator wishes, unless the image data for transmission and the image checking display data are deleted. Also, since the image checking display data is generated and stored in the Box storage area of the external storage device 105, even when the operator has not instructed to check the image data for transmission, the operator can check the image data for transmission instantly, if he/she wants to do so later. Therefore, the operator is free from stress derived from an otherwise entailed waiting time before generation of the image checking display data, and hence operability is greatly improved.

In the step S408, the process shown in FIG. 3 is performed on the assumption that the instruction has been inputted to generate image checking display data (YES to the step S303), whereby both image data for transmission and its image checking display data are generated. Then, in a step S409, a preview image based on the image checking display data is displayed on the display 103. As a result, the operator can check how the image looks like before transmitting the image data.

In a step S410, the operator determines whether to send the image data for transmission or not after the checking, and the process proceeds to a step S411 according to an instruction from the operation if the image data for transmission is to be transmitted, or the process is terminated if the image data is not to be transmitted.

In the step S411, similarly to the step S403, it is determined whether or not the identifier of a Box storage area in the external storage device 105 is contained in the address field 202. If the identifier is contained, the process proceeds to the step S407, and if the identifier is not contained, the process proceeds to the step S405.

In a step S412, only the image data for transmission is read from the temporary image data storage area or the Box storage area of the external storage device 105 and transmitted to an address other than the address represented by the identifier of the Box storage area contained in the field 202. The process is then terminated.

On the other hand, in a step S413, the image data for transmission stored in the Box storage area of the external storage device 105 in the step S407 is transmitted to the address represented by the identifier of the Box storage area, and then the process is terminated.

As descried above, according to the first embodiment, even when the instruction for checking the read image data has been given (NO to the step S402), if the identifier of a Box storage area in the external storage device 105 is contained in the address field 202(YES to the step S403), image data for transmission and its image checking display data are generated (step S406), and the image data for transmission is stored along with the image checking display data in the Box storage area of the external storage device 105 to which is assigned the identifier inputted in the address field 202 (step S407). As a result, by reading the image checking display data from the Box storage area of the external storage device 105 and displaying these data on the display device 103 upon request to display these data for checking, which is given later, the image checking display data can be quickly displayed on the display device 103 and hence the image data for transmission can be quickly checked.

Next, a second embodiment of the present invention will be described.

The second embodiment has basically the same hardware configuration as that of the first embodiment, and thus the hardware configuration of the first embodiment described above will be referred to in the description of the second embodiment.

In the second embodiment, the procedure for reading, checking, storing, and transmitting an image executed by the image reading and transmitting apparatus 1 differs from that of the first embodiment shown in FIGS. 4A and 4B.

FIGS. 5A and 5B are flowchart showing a procedure for reading, checking, storing, and transmitting an image executed by the image reading and transmitting apparatus 1 according to the second embodiment, according to instructions inputted to the instruction input screen.

In a step S501, it is determined whether or not the scan/send start button 203 on the image input screen of FIG. 2 has been pressed. If the button 203 has been pressed, the process proceeds to a step S502. If the button 203 has not been pressed, the process returns to the step S501 to wait for the button 203 to be pressed.

Then, in the step S502, it is determined whether or not the preview instruction button 201 in FIG. 2 has been pressed. If the button 201 has been pressed, the process proceeds to a step S508, and if the button 201 has not been pressed, the process proceeds to a step S503, where it is determined whether or not the identifier of a Box storage area in the external storage device 105 or the MAC address of the database server 2 set by pressing the button “DB” is contained in the address field 202. If at least one of the identifier and the MAC address is contained, the process proceeds to a step 8506. If neither of them is contained, the process proceeds to a step S504.

In the step S504, the process shown in FIG. 3 is performed on the assumption that no instruction has been inputted to generate image checking display data (NO to the step S303), whereby only image data for transmission is generated, and then, in a step S505, the image data generated in the step S504 is stored in the temporary image data storage area of the external storage device 105.

In the step S506, the process shown in FIG. 3 is performed with the assumption that an instruction has been inputted to generate image checking display data (YES to the step S303), whereby both image data for transmission and its image checking display data are generated. And then, in a step S507, the image data for transmission and the image checking display data are stored in the Box storage area of the external storage device 105 to which is assigned an identifier if the identifier is contained in the address field 202, or transmitted to the database server 2 corresponding to a MAC address if the MAC address is contained in the field 202. If both the identifier and the MAC address are contained in the address field 202, the above two data are stored in the Box storage area corresponding to the identifier and the database server corresponding to the MAC address. By thus storing, in the step S507, the image data for transmission in the Box storage area of the external storage device 105 and/or the database server 2 together with its image checking display data, the operator can read the image data for transmission from the Box storage area of the external storage device 105 or from the database server 2, for transmitting the image data for transmission to different addresses and checking or previewing the image through the image checking display data as many times as the operator wishes, unless the image data for transmission and the image checking display data are deleted. Also, since the image checking display data is generated and stored in the Box storage area of the external storage device 105 and the database server 2, even when the operator has not instructed to check the image data for transmission, the operator can check the image data for transmission instantly, if he/she wants to do so later. Therefore, the operator is free from stress derived from an otherwise entailed waiting time before generation of the image checking display data, and hence operability is greatly improved.

In the step S508, the process shown in FIG. 3 is performed on the assumption that the instruction has been inputted to generate image checking display data (YES to step S303), whereby both image data for transmission and its image checking display data are generated. Then, in a step S509, a preview image based on the image checking display data is displayed on the display 103. As a result, the operator can how the image looks like before transmitting the image data for transmission.

In a step S510, the operator determines whether to send the image data for transmission or not after the checking, and the process proceeds to a step S511 according to an instruction from the operator if the image data for transmission is to be transmitted, or the process is terminated if the image data is not to be transmitted.

In a step S511, similarly to the step S503, it is determined whether or not the identifier of the Box storage area in the external storage device 105 and/or the MAC address of the database server 2 is contained in the address field 202, and if at least one of the identifier and the MAC address is contained, the process proceeds to the step S507, and if neither of the identifier and the MAC address is contained, the process proceeds to the step S505.

In a step S512, only the image data for transmission is read from the temporary image data storage area or the Box storage area of the external storage device 105 and transmitted to an address other than the address represented by the identifier and the MAC address contained in the field 202, and then the process is terminated.

On the other hand, in a step S513, the image data for transmission stored in the Box storage area of the external storage device 105 in the step S507 is transmitted to the address represented by the identifier of the Box storage area, and then the process is terminated.

As descried above, according to the second embodiment, even when the instruction for checking the read image data has been given (NO to the step S502), if the identifier of a Box storage area in the external storage device 105 is contained in the address field 202(YES to the step S503), image data for transmission and its image checking display data are generated (step S506), and the image data for transmission is stored along with the image checking display data in the Box storage area of the external storage device 105 to which is assigned the identifier inputted in the address field 202 and the database server 2 (step S507). As a result, by reading the image checking display data from the Box storage area of the external storage device 105 or the database server 2 and displaying these data on the display device 103 upon request to display these data for checking, which is given later, given later, the image checking display data can be quickly displayed on the display device 103 and hence the image data for transmission can be quickly checked.
