  FIG. 2 particularly shows a cross-sectional view of the reader unit 1 and the printer unit 2. The document feeder 101 of the reader unit 1 feeds a plurality of documents set at a predetermined placement location by the user onto the platen glass 102 one by one in order from the first page to the last page. Then, the document feeder 101 discharges the document on the platen glass 102 to a predetermined discharge location after completion of the document reading operation. When the document is conveyed onto the platen glass 102, the lamp 103 is turned on, the movement of the scanner unit 104 is started, and the document is exposed and scanned.

  Reflected light from the original at this time is irradiated to a CCD image sensor (hereinafter referred to as CCD) 109 by mirrors 105, 106, 107 and a lens 108. As described above, the scanned image of the document is photoelectrically converted by the CCD 109 to become electric signal data. Image data output from the CCD 109 is subjected to desired image processing such as A / D conversion, shading correction, and color conversion, and then transferred to the core unit 10 of the image input / output control unit 4.

  The laser driver 221 of the printer unit 2 drives the laser light emitting unit 201 to cause the laser light emitting unit 201 to emit a laser beam having a light amount corresponding to the image data output from the core unit 10 of the image input / output control unit 4. This laser light irradiates the photosensitive drum 202, and the photosensitive drum 202 forms a latent image corresponding to the laser light. The developing device 203 attaches a developer to the latent image portion of the photosensitive drum 202.

  In addition, at a timing synchronized with the start of laser light irradiation, a recording sheet is fed from one of the cassettes 204 to 205 via the sheet feeding roller 211 to the sheet feeding roller 212 and the sheet feeding roller 213. It is conveyed to the transfer unit 206. The transfer unit 206 transfers the developer attached to the photosensitive drum 202 onto a recording sheet. The recording sheet to which the developer has been transferred is conveyed to the fixing unit 207, and the developer is fixed to the recording sheet by the heat and pressure of the fixing unit 207.

  The recording paper that has passed through the fixing unit 207 is discharged by a discharge roller 208, and the finisher 220 bundles a plurality of discharged recording papers and sorts them, or performs stapling processing at a desired position of the sorted recording papers. To go. Thereafter, the processed recording paper is discharged to a paper discharge tray.

  If double-sided recording is set, the recording paper on which single-side recording is performed up to the discharge roller 208 is conveyed, and then the rotation direction of the discharge roller 208 is reversed and guided to the refeed conveyance path 210 by the flapper 209. . The recording paper guided to the refeed conveyance path 210 is fed to the transfer unit 206 at the timing described above, and image recording is performed on the opposite surface. Thereafter, the processed recording paper is discharged to a paper discharge tray.

[Core]
FIG. 4 is a block diagram showing a detailed configuration of the core unit according to the embodiment of the present invention.

  The image data transferred from the reader unit 1 is transferred to the data processing unit 121 via the interface (I / F) 122. The data processing unit 121 performs image processing such as image rotation processing and scaling processing, and compression and decompression of image data, and has a page memory 125 capable of storing a predetermined amount of predetermined image data therein. The core unit 10 temporarily stores the image data transferred from the reader unit 1 to the data processing unit 121 in the page memory 125, compresses the image data, and transfers the compressed image data to the storage unit 6 via the interface 120.

  Code data (PDL) representing an image transferred via the computer interface unit 7 is transferred to the data processing unit 121 via the interface 120 and then returned to the RIP unit 8 once. The RIP unit 8 converts the received code data into image data, and transfers the converted image data to the data processing unit 121 again. The core unit 10 temporarily stores the image data received from the RIP unit 8 in the page memory 125, and then compresses and transfers the image data to the storage unit 6.

  The image data transferred from the facsimile unit 5 is transferred to the data processing unit 121, temporarily stored in the page memory 125, compressed, and transferred to the storage unit 6.

  The image data transferred from the storage unit 6 is transferred to the data processing unit 121, decompressed and temporarily stored in the page memory 125, and then the printer unit 2, display unit 3, facsimile unit 5, computer interface unit 7. Forwarded to

  The core unit 10 transmits various image data to the data processing unit 121, temporarily stores the image data in the page memory 125, and then transfers the image data to the storage unit 6. In addition to this, the core unit 10 can transfer to the printer unit 2, the facsimile unit 5, and the computer interface unit 7, and a plurality of combinations of transfer destinations can be executed by switching an internal selector.

  In the above example, the storage unit 6 is in the image processing apparatus. However, the storage unit 6 may be stored in an external device (server) outside the network.

[Display control]
Next, display processing when image data is displayed on the display unit 3 from the reader unit 1 in the image processing apparatus according to the present embodiment will be described with reference to FIG.

  FIG. 5 is a flowchart showing display processing according to the embodiment of the present invention.

  When the display of the read image from the reader unit 1 on the display unit 3 is instructed from the operation unit 9, this processing is started.

  In step S <b> 601, the read image from the reader unit 1 is stored in the storage unit 6 via the image input / output control unit 4 and the core unit 10. The stored image data is subjected to desired data compression, and the image data is stored in the hard disk 61 together with an ID number that can be uniquely specified.

  When the storage in the storage unit 6 is completed, the core unit 10 reads out the image data stored in the storage unit 6 in step S602. Then, the data processing unit 121 executes image processing such as resolution and color suitable for decompression of the read compressed image data and display on the display unit 3. Thereafter, the image data (read image) is displayed on the display unit 3 by transferring the image data to the display unit 3.

  In step S <b> 603, the storage unit 6 performs data analysis on the image data (read image) stored in the storage unit 6. Here, feature amounts such as character extraction and image features included in the data are extracted. Note that various methods known in the art can be used for detailed methods of character extraction and image feature extraction, but this is not the main point of the present proposal and is omitted.

  In step S604, based on the analysis result, the storage unit 6 compares the image data already stored in the hard disk 61 with the image data (read image), and calculates the similarity between them. For the details of the similarity calculation method, various methods known in the art can be used, but this is not the main point of the present proposal and will be omitted.

  In step S605, based on the calculation result obtained in step S604, the storage unit 6 determines whether the similarity is equal to or higher than a predetermined first threshold value. If it is less than the first threshold (NO in step S605), the process ends. On the other hand, if the position is equal to or greater than the first threshold position (YES in step S605), the process proceeds to step S606 to determine whether the similarity is equal to or greater than a predetermined second threshold value.

  If the similarity is greater than or equal to the second threshold (YES in step S606), the process proceeds to step S607. In this case, when the similarity equal to or higher than the predetermined second threshold is obtained, that is, image data that can be regarded as matching with the original image data (original image data) of the read image is stored in the storage unit 6. This is the case.

  In this case, the image data having the maximum similarity is transferred to the core unit 10 in the storage unit 6 in step S607. The core unit 10 performs image processing such as resolution and color suitable for decompression of the image data, processing in the RIP unit 8, and display on the display unit 3 based on the form of the transferred image data. The subsequent image data is transferred to the display unit 3. As a result, the displayed read image is replaced with the original image data.

  In this case, since the original image data that can be regarded as the read image is already stored in the hard disk 61, the image data of the read image stored in the hard disk 61 in step S601 is deleted. Also good. As a result, the amount of data such as image data stored in the hard disk 61 by the image processing apparatus can be adaptively reduced according to the necessity of the original image data without increasing unnecessary redundancy.

  On the other hand, if the similarity is less than the second threshold (NO in step S606), the process proceeds to step S608. In this case, if a similarity less than the predetermined second threshold is obtained, that is, it cannot be regarded as coincident with the original image data of the read image, but image data similar to the read image is stored to some extent. This is a case where it is stored in the part 6.

  In this case, in step S608, the core unit 10 indicates on the display unit 3 that a candidate for the image data that is the source of the read image has been obtained, and displays the image data in accordance with the operation for that. A candidate image display instruction section to be executed is displayed.

  More specifically, an operation control (for example, an icon) for realizing the candidate image display instruction unit is displayed as an overlay on the image data of the read image on a part of the image data currently displayed on the display unit 3. Alternatively, an operation screen for realizing a candidate image display instruction unit including candidates for image data corresponding to the read image (or its thumbnail image (representative image)) is displayed as an overlay on the image data of the read image, and a desired image is selected from the operation screen. Data selection may be accepted. In addition, this operation screen can be modified such that, if there is a blank portion, it is displayed in that portion instead of being displayed in an overlay in the image.

  In step S <b> 609, based on a display instruction from the operator for the operation control (icon) displayed on the display unit 3, image data having the maximum similarity in the image data group less than the second threshold is displayed on the display unit 3. . When the operation dialog is displayed, the image data selected in the operation dialog is displayed on the display unit 3.

  In this case, an instruction means (for example, an instruction screen or an instruction unit) for instructing whether or not to use the displayed image data as a read image is displayed to prompt the user to determine whether or not the image data is necessary. Is possible. In particular, when it is instructed to adopt the image data as a read image, the image data of the read image stored in the hard disk 61 in step S601 may be deleted.

  The first threshold value and the second threshold value are used to determine the degree of similarity between the read image and the image data stored in the storage unit 6. In addition, the relationship is first threshold <second threshold. These two types of threshold values are normally stored in advance in the memory 124, but if necessary, a setting screen (not shown) for setting the threshold values is called on the display unit 3, The value can be arbitrarily changed by the user via the setting screen.

  Here, in this embodiment, when the similarity is less than the first threshold, the image data to be compared is image data that cannot be regarded as a read image. Further, when the similarity is equal to or higher than the first threshold and lower than the second threshold, the image data to be compared is somewhat similar to the read image, but matches the original image data of the read image. The image data cannot be considered. Furthermore, when the similarity is equal to or higher than the second threshold, the image data to be compared is image data that can be regarded as matching with the image data that is the original of the read image.

  Therefore, if there is a similarity greater than or equal to the second threshold, the image data to be compared is displayed on the display unit 3 as the original image data of the read image instead of the read image (step S607). Thereby, the original image data whose image quality is better than that of the read image is displayed on the display unit 3, and the user can visually recognize the content better. Here, especially when the read original of the read image is black and white and the corresponding original image data is a color image, the color original image data is displayed for the black and white read image. The visual recognition effect becomes larger.

  On the other hand, when the similarity is equal to or higher than the first threshold and lower than the second threshold, there is image data that is a candidate for the original image data of the read image, and a candidate image display instruction unit for displaying the image data is displayed. The information is displayed on the display unit 3 (step S608). In this case, the user can display the candidate image data on the display unit 3 as a read image by operating the candidate image display instruction unit.

  Next, when the original image data includes audio, a slide show of multiple images, and a moving image, the display processing when the display of the read image data is replaced with the display of the original data will be described with reference to FIG. explain.

  FIG. 6 is a flowchart showing an application example of display processing according to the embodiment of the present invention.

  When the display of the read image from the reader unit 1 on the display unit 3 is instructed from the operation unit 9, this processing is started. In FIG. 6, the same step number is added to the same process in FIG. 5, and the details of the process are omitted.

  If the similarity is greater than or equal to the second threshold in step S606 (YES in step S606), the process proceeds to step S707. In this case, when the similarity equal to or higher than the predetermined second threshold is obtained, that is, image data that can be regarded as matching with the original image data (original image data) of the read image is stored in the storage unit 6. This is the case.

  In this case, the image data having the maximum similarity is transferred to the core unit 10 in the storage unit 6 in step S707. The core unit 10 performs image processing such as resolution and color suitable for decompression of the image data, processing in the RIP unit 8, and display on the display unit 3 as necessary based on the form of the transferred image data. Thereafter, the processed image data is transferred to the display unit 3. As a result, the displayed read image is replaced with the original image data.

  In step S708, if the original image data includes media information such as audio, a slide show of multiple images, and moving images as related information, the media information and its attribute information are used as related objects. Transfer to the display unit 3. In addition to this, the media information operating means based on the attribute information (type, display position, etc.) is transferred to the display unit 3.

  For example, in the case of audio or moving images, this operation means includes an operation unit (operation control) for performing operations such as playback / stop / fast forward / rewind / pause / image size change. Further, in the case of a slide show format image in which a plurality of images are combined, there is an operation unit (operation control) for performing operations such as reproduction and pause.

  Thereby, the display unit 3 displays the original image data, the related object, and the operation unit for operating the related object. Then, when there is an operation instruction from the operator with respect to the operation unit displayed on the display unit 3, an operation is performed on the media based on the operation instruction.

  For example, if the operation instruction is a reproduction operation for a moving image, the moving image data to be the operation instruction stored in the storage unit 6 is transmitted to the core unit 10, and the core unit 10 performs data conversion for moving image reproduction / display. And transfer to the display unit 3. As a result, the user can operate the related objects in the original image data on the display unit 3.

  On the other hand, if the similarity is less than the second threshold value in step S606 (NO in step S606), the above-described steps S608 and S609 are executed. However, after step S609 is executed, the process of step S708 may be executed to display the operation unit of the related object in the original image data.

  Next, a specific example in the processing of FIG. 6 will be described with reference to FIG.

  FIG. 7 is a diagram for explaining a specific example in the processing of FIG. 6 according to the embodiment of the present invention.

  FIG. 7 shows transition of images displayed on the display unit 3. In FIG. 7, reference numeral 1000 denotes a read image, which is a state after the processing in step S602. If the original image 2000 exists as an image having a similarity equal to or higher than the second threshold for the scanned image 1000 through steps S603 to S606, the original image 2000 is displayed on the display unit 3 in step S707.

  Since the original image 2000 includes a moving image as a related object, images 2001 and 2002 indicating the moving image are displayed in the original image. In addition to this, operation units 2001a and 2002a for operating (reproducing) these images are displayed.

  Accordingly, the user can display the original image 2000 whose contents are more easily visible instead of the read image, and can perform the operation when there is a related object. .

  As described above, according to the present embodiment, when an image corresponding to a read image is displayed, if the image that is the source of the image exists, the image that is the source is displayed instead of the read image. To do. Furthermore, when there is a related object related to the original image, an operation environment for operating the related object is provided. As a result, an image corresponding to the read image can be displayed more appropriately, and when a related object exists in the image that is the basis of the read image, it is possible to provide a suitable operation environment for the related object.
