[0010]
FIG. 2 is a block diagram showing a detailed configuration of the image forming apparatus shown in FIG. As shown in FIG. 2, the control unit 111 is connected to a scanner 113 that is an image input device and a printer 114 that is an image output device, and on the other hand, is connected to a LAN 100 or a public line (WAN) 102 to thereby obtain image information. It is a controller that inputs and outputs device information.
[0011]
In the control unit 111, the CPU 201 controls the entire apparatus. A RAM 202 is a system work memory used when the CPU 201 executes processing. The RAM 202 is also an image memory for temporarily storing image data. A ROM 203 is a boot ROM, and stores a boot program and control data of the apparatus. An HDD 204 is a hard disk drive that stores system software and image data.
[0012]
The operation unit I / F 206 controls an interface with the operation unit (UI) 112 and outputs image data to be displayed on the operation unit 112 to the operation unit 112. Further, it plays a role of transmitting instruction information input by the user via the operation unit 112 to the CPU 201.
[0013]
A network interface 208 is connected to the LAN 100 and inputs / outputs information to / from the LAN 100. A modem (MODEM) 209 controls connection to the public line 102 and inputs / outputs information to / from the public line 102. The image companding unit 210 performs JPEG compression / decompression processing for multi-valued image data, and JBIG, MMR, and MH compression / decompression processing for binary image data. The above devices are arranged on the system bus 207.
[0014]
An image bus interface (Image Bus I / F) 205 is a bus bridge that connects a system bus 207 and an image bus 220 that transfers image data at high speed, and converts a data structure. The image data is compressed on the system bus 207 and converted so that uncompressed image data flows on the image bus 220. The image bus 220 is generally composed of a PCI bus or IEEE1394.
[0015]
The following devices are arranged on the image bus 220. A raster image processor (RIP) 211 expands a PDL code transmitted from the network 100 into a bitmap image. The device I / F unit 212 connects the scanner 113, the printer 114, which are image input / output devices, and the control unit 111 via predetermined interfaces 221 and 222, and performs synchronous / asynchronous conversion of image data.
[0016]
A scanner image processing unit 213 corrects, processes, and edits input image data. Further, it has a function of judging whether the input image is a color document or a monochrome document from the saturation signal of the image and holding the result. The printer image processing unit 214 corrects, processes, and edits the print output image data. The image rotation unit 215 cooperates with the scanner image processing unit 213 to rotate the image simultaneously with reading of the image from the scanner 113 and store the image on the memory, rotate the image on the memory to store it on the memory, or The image on the memory can be printed out while being rotated in cooperation with the printer image processing unit 214.
[0017]
The resolution converter 216 converts the resolution of the image data on the memory and stores it on the memory. The color space conversion unit 217 converts, for example, a YUV image on the memory into a Lab image by matrix calculation, and stores it on the memory. The gradation conversion unit 218 converts, for example, 8-bit, 256-gradation image data on the memory into 1-bit, 2-gradation by a technique such as error diffusion processing, and stores it on the memory.
[0018]
Note that the image rotation unit 215, the resolution conversion unit 216, the color space conversion unit 217, and the gradation conversion unit 218 can operate in conjunction with each other. For example, in the case of image rotation and resolution conversion of an image on a memory. Both processes can be performed without going through the memory.
[0019]
FIG. 3 is a block diagram showing a configuration of the scanner image processing unit 213 shown in FIG. The RGB 8-bit luminance signals input from the scanner 113 are converted into standard RGB color signals that do not depend on the CCD filter color by the masking unit 301. The converted RGB color signal is subjected to scaling processing by the scaling unit 302 when scaling is necessary. The subsequent filter 303 performs processing to blur or sharpen the image, and the gamma unit 304 performs processing to increase or decrease the density of the entire image.
[0020]
Further, in order to determine whether the document is color or monochrome, the color space conversion unit 305 converts the image signal before scaling into a known Lab space image signal. Of these, a and b represent color signal components, and a 1-bit determination signal is output from the comparator 306 as a chromatic color if it is equal to or higher than a predetermined level in the comparator 306, and as an achromatic color otherwise. The counter 307 counts the output from the comparator 306.
[0021]
Further, the character / photo determination unit 308 extracts character edges from the RGB signals output from the masking unit 301, and separates the input image into characters and photos. As an output, a “character photo determination signal” is obtained. This signal is also stored together with the image in a memory or HD (hard disk) and used during printing.
[0022]
On the other hand, the specific document determination unit 309 can compare the input image signal and the degree to which the pattern held in the determination unit matches, and can output a determination result of matching or mismatching as shown. And according to a determination result, an image can be processed and forgery, such as a banknote and a securities, can be prevented.
[0023]
FIG. 4 is a diagram illustrating an appearance of the image forming apparatus according to the present embodiment. 4 scans an image on a document with a CCD line sensor (not shown), optically reads the image, generates raster image data, and outputs the raster image data. When the user sets an original on the tray 406 of the original feeder 405 and instructs the start of reading in the operation unit 112, the controller CPU 201 gives an instruction to the scanner 113, and the feeder 405 feeds the original one by one. Reads an image on the document.
[0024]

The CPU 201 comprehensively controls access to various devices connected to the system bus 207 based on a control program stored in the ROM 203 and the HDD 204. In addition, the CPU 201 reads input information from the scanner 113 connected via the device I / F 212 and outputs an image signal as output information to the printer 114 connected via the device I / F 212. The RAM 202 functions as a main memory, work area, and the like for the CPU 201.
[0029]
In FIG. 6, user inputs from the touch panel 502 and various hard keys 503, 504, 505, and 507 are passed to the CPU 201 via the input port 601. The CPU 201 generates display screen data based on the contents of the user input and the control program, and outputs the display screen to the LCD display unit 501 via the output port 602 that controls the screen output device. Further, the CPU 201 controls the LED display 506 as necessary.
[0030]
Next, processing such as copy, transmission, and box in this embodiment will be described using a screen displayed on the LCD display unit 501.
[0031]

Reference numeral 806 is for automatically determining the density when reading an image with a background such as a newspaper.
[0035]
Next, software executed by the CPU 201 of the control unit 111 of the image forming apparatus according to this embodiment having the above-described configuration will be described.
[0036]
FIG. 9 is a diagram illustrating a software configuration in the image forming apparatus. In FIG. 9, reference numeral 901 denotes a UI control unit that controls the operation unit 112 as a user interface. A copy application unit 902 receives an instruction from the UI control unit 901 and controls a predetermined device control unit to execute a copy job. A transmission application unit 903 controls a predetermined device control part to execute a transmission job. Reference numeral 904 denotes a BOX application unit that temporarily stores image data. A PDL application unit 905 receives data from the network application unit 916 and inputs a PDL print job. Reference numeral 906 denotes a common interface unit that absorbs the device-dependent portion of the device control portion.
[0037]
A job manager 907 arranges various job information received from the common interface unit 906 and transmits the job information to a lower-level document processing unit. Here, the document processing unit is a scan manager 909 and a print manager 913 for a local copy, and a scan manager 909 and a file store manager 914 for a remote copy transmission job or transmission job, and a remote copy reception job. If so, the file read manager 910 and the print manager 913 are used. If PDL printing such as LIPS or PostScript is used, the PDL manager 911 and the print manager 913 are used.
[0038]
Note that synchronization and image processing requests between the document processing units are performed via the sync manager 912, and image processing and image file storage during scanning and printing are performed by the image manager 915.
[0039]
First, local copy software processing in the above-described software configuration will be described. A copy setting is transmitted from the UI control unit 901 to the copy application unit 902 in accordance with a user instruction. As a result, the copy application unit 902 transmits information from the UI control unit 901 to the job manager 907 that performs control via the common interface unit 906. Then, the job manager 907 transmits job information to the scan manager 909 and the print manager 913.
[0040]
The scan manager 909 issues a scan request to the scanner 113 via the device I / F 212. At the same time, an image processing request is issued to the image manager 915 via the sync manager 912. The image manager 915 sets the scanner image processing unit 213 in accordance with an instruction from the scan manager 909. When this setting is completed, a scan preparation completion is notified via the sync manager 912. Thereafter, the scan manager 909 instructs the scanner 113 to scan.
[0041]
Here, the completion of the scan image transfer is transmitted to the image manager 915 by an interrupt signal from hardware (not shown). Upon receiving the scan completion from the image manager 915, the sync manager 912 notifies the scan completion to the scan manager 909 and the print manager 913. At the same time, the sync manager 912 instructs the image manager 915 to file the compressed image stored in the RAM 202 into the HDD 204. The image manager 915 stores the JPEG image (including the character / photo determination signal) on the memory in the HDD 204 according to the instruction. It should be noted that, as the accompanying information of the image, the color determination / monochrome determination result, the scanned image as the image input source, the color space RGB, and the information that the screen is used for the scanned image as image processing are also stored in the SRAM not shown.
[0042]
Further, when the image manager 915 finishes storing in the HDD 204 and receives a scan completion from the scanner 113, the image manager 915 notifies the scan manager 909 via the sync manager 912 of the completion of file creation. Then, the scan manager 909 returns an end notification to the job manager 907, and the job manager 907 returns it to the copy application unit 902 via the common interface unit 906.
[0043]
On the other hand, the print manager 913 issues a print request to the printer 114 via the device I / F 212 when an image enters the memory, and issues a print image processing request to the sync manager 912. When the sync manager 912 receives a request from the print manager 913, it requests the image manager 915 to perform image processing settings. Then, the image manager 915 sets the printer image processing unit 214 in accordance with the above-described image accompanying information, and notifies the print manager 913 of completion of print preparation via the sync manager 912. Then, the print manager 913 issues a print instruction to the printer 114.
[0044]
Here, the completion of the print image transfer is transmitted to the image manager 915 by an interrupt signal from hardware (not shown). Upon receiving the print completion from the image manager 915, the sync manager 912 notifies the print manager 913 of the print completion. In addition, the print manager 913 receives the completion of paper discharge from the printer 114 and returns an end notification to the job manager 907, and the job manager 907 returns it to the copy application unit 902 via the common interface unit 906. Then, the copy application unit 902 notifies the UI control unit 901 of the job end when scanning and printing are completed.
[0045]
Next, in the case of a remote copy scan job or transmission job, the file store manager 914 receives a request from the job manager 907 instead of the print manager 913. When the scan image has been stored in the HDD 204, the storage manager 912 receives a storage completion notification from the sync manager 912, and notifies the copy application unit 902 for remote copy and the transmission application unit 903 for a transmission job via the common interface unit 906. . Then, after this notification, the copy application unit 902 and the transmission application unit 903 request the network application unit 916 to transmit the file stored in the HDD 204. Upon receiving this request, the network application unit 916 transmits the file.
[0046]
The network application unit 916 receives setting information regarding copying from the copy application unit 902 at the start of the job, and notifies the remote side of the setting information. In the case of remote copy, the network application unit 916 performs transmission using a device-specific communication protocol. In the case of a transmission job, a standard file transfer protocol such as FTP or SMB is used. In the case of fax transmission, after the file is stored, the transmission application unit 903 instructs the FAX manager 908 to transmit via the common interface unit 906 and the job manager 907. If there is a printer at the transmission destination, the transmission application unit 903 issues a print instruction as a print job via the common interface unit 906. The operation at that time is the same as that of the remote copy print job described below. When the transmission destination is a box destination in the device, it is stored in the file system in the device.
[0047]
Next, in the case of a remote copy print job, the network application unit 916 stores the image from the transmission side in the HDD 204 and issues the job to the copy application unit 902. As a result, the copy application unit 902 inputs a print job to the job manager 907 via the common interface unit 906. In this case, unlike the local copy, the file read manager 910 receives a request from the job manager 907 instead of the scan manager 909.
[0048]
A request for expanding the received image from the HDD 204 to the memory is made to the image manager 915 via the sync manager 912. The image manager 915 expands the image in the memory. When the development is completed, the image manager 915 notifies the file read manager 910 and the print manager 913 of the completion of the development via the sync manager 912. When an image is stored in the memory, the print manager 913 selects a paper feed stage designated by the job manager 907 or a stage having the paper size via the device I / F 212 and issues a print request. In the case of automatic paper, the paper feed stage is determined from the image size and a print request is issued.
[0049]
The print manager 913 makes a print image processing request to the sync manager 912. When the sync manager 912 receives a request from the print manager 913, it requests the image manager 915 to perform image processing settings. Here, for example, if there is no optimal size paper and rotation is required, a separate rotation instruction is also requested. In addition, when there is a rotation instruction, the image manager 915 causes the image rotation unit 215 to rotate the image. The image manager 915 sets the printer image processing unit 214 and notifies the print manager 913 that the print preparation is complete via the sync manager 912. Then, the print manager 913 issues a print instruction to the printer 114.
[0050]
Here, the completion of the print image transfer is transmitted to the image manager 915 by an interrupt signal from hardware (not shown). Upon receiving the print completion from the image manager 915, the sync manager 912 notifies the file read manager 910 and the print manager 913 of the print completion. The file read manager 910 returns an end notification to the job manager 907. Also, the print manager 913 receives the completion of paper discharge from the printer 114 and returns an end notification to the job manager 907. The job manager 907 returns an end notification to the copy application unit 902 via the common interface unit 906. Then, the copy application unit 902 notifies the UI control unit 901 of the job end when scanning and printing are completed.
[0051]
Next, in the case of a PDL data development storage job, a request from the host PC that has input the PDL print is transmitted to the PDL application unit 905 via the network application unit 916. Then, the PDL application unit 905 instructs the job manager 907 via the common interface unit 906 for a PDL data development storage job. At this time, the PDL manager 911 and the file store manager 914 receive a request from the job manager 907. The processing from the end of image development to image input is the same as the scan job described above. A JPEG image (including a character / photo determination signal) on the memory is stored in the HDD 204. It should be noted that color / monochrome information is stored in an SRAM (not shown) as accompanying information of the image, PDL image as the image input source, color space CMYK, and information that the screen is for PDL image as image processing. The image processing screen can be arbitrarily set by the user, and information called user definition may be stored.
[0052]
When the PDL is stored in the HDD 204, a storage completion notification is received from the sync manager 912, and this is notified to the PDL application unit 905 via the common interface unit 906. After this notification, the PDL application unit 905 notifies the network application unit 916 of the storage completion to the HDD 204, and this information is transmitted to the host PC that has entered the PDL print.
[0053]
Next, for printing an image that has been developed and stored in PDL, the BOX application unit 904 issues a stored document instructed to be printed on the UI 901 as a job. The BOX application unit 904 inputs a print job to the job manager 907 via the common interface unit 906. In this case, unlike the local copy, the file read manager 910 receives a request from the job manager 907 instead of the scan manager 909. A request for expanding the image instructed to be printed from the HDD 204 to the memory is made to the image manager 915 via the sync manager 912. The subsequent operation is the same as that described in the remote copy print job, and is therefore omitted.
[0054]
Next, at least an image file for transmission / printing and an image file for display to be displayed on the operation unit 112 are generated from a scanned image or a PDL input image with respect to a specific document serving as the center of the present embodiment, and a hard disk (HDD) The processing when storing the file will be described.
[0055]
FIG. 10 is a diagram showing a flow of image processing in the present embodiment. As shown in the figure, the scanned or PDL developed image is processed from the left side to the right side shown in FIG. “◯” represents image processing, and “□” represents an image on the memory. Reference numeral 1005 corresponds to the hard disk (HDD) 204 shown in FIG.
[0056]
First, image processing 1001 is performed on an input image that has been scanned or PDL developed, and the processed image 1011 is stored in the RAM 202. Next, a scaling process and a rotation process 1002 which are processes common to transmission / printing and image display are performed. The result is stored in the RAM 202 as an image 1012.
[0057]
Next, color space conversion processing (YUV → YCbCr) 1003 for the transmission image is performed. Then, when storing the converted image, a known JFIF header is described in advance in the RAM 202, and writing is continued from there to store it as the converted image 1013. In addition, when a destination such as FAX that can transmit only a binary image is specified, a known TUFF header is described, and then a multi-value → binary conversion process 1003 is performed to obtain a converted image 1013. Store. Note that no special processing is performed for printing. Then, the transmission image is stored in the HDD 1005 as a transmission image file in JFIF / TUFF format by the conversion image 1013 written to the HDD 1004. On the other hand, the print image is stored in the HDD 1005 as a TIFF format print image file.
[0058]
Further, in order to display on the operation unit 112, the above-described image 1012 is converted into an image for display (sampling according to the display area, for example, by generating one pixel of 32 × 32 pixels, a 1/32 size image is obtained. The display image (preview image) is stored in the HDD 1005 in the TIFF file format by the conversion process to be converted and the write process 1008 to the HDD. Identification information for identifying the processing file is added to the header of each image file stored in the HDD 1005. Further, each file and each application 902 are added to the HDD 1005. Has a table for associating .about.905.
[0059]
Next, when transmitting or printing, the stored transmission / print image file is read as an image 1014 by the HDD read processing 1006 based on the identification information and the table, and the read image 1014 is transmitted by the application 1007. Print.
[0060]
When the image is preview-displayed, the TIFF file of the stored image is read as an image 1015 by the HDD reading process 1009 based on the identification information and the table and displayed on the operation unit 112.
[0061]
[Error display processing]
Next, in order to send / print or preview the image stored in the hard disk (HDD), a file in a corresponding format is read. If an error occurs, an error message is displayed according to the type of the file. The process of changing the will be described.
[0062]
In the above-described read processing 1006 and 1009 from the hard disk (HDD), there is a possibility that an HDD read error due to file corruption or the like will occur. In contrast, when an error is detected in copy printing, the image manager 915 notifies the UI 901 via the sync manager 912, print manager 913, job manager 907, common interface 906, and copy application 902, and the power is turned off. / ON is displayed as an error that requires ON. Further, when an error is detected in printing from the BOX, the UI 901 is notified via the BOX application 904 instead of the copy application 902. Similarly, when an error is detected in PDL printing, the UI 901 is notified via the PDL application 905. On the other hand, when an error is detected in image transmission, the UI 901 is notified via the image transmission application 903.
[0063]
On the other hand, a TIFF file is directly read out by the UI 901 as an image to be displayed for preview. Here, when the size of the image is first read out, if the size in the header is “0”, it cannot be displayed. Therefore, a reading error is displayed on the screen indicating that the image cannot be displayed. Even if the preview display is not possible, there is no problem in the transmission or printing operation, and thus this processing is performed.
[0064]
FIG. 11 is a flowchart showing error display processing in the UI 901. First, in step S1101, when an error occurrence is notified to the UI 901, it is determined whether or not the error is an error event from each application such as the copy application 902, the BOX application 904, and the PDL application 905. The error event information includes the identification information and file type information based on the table. Therefore, by this determination processing, the type of the image file related to the error is an image print file processed by the copy application 902, the BOX application 904, the PDL application 905, or the like, or an image transmission file processed by the image transmission application 903. Can be determined.
[0065]
If it is an error event from each of these applications, the file type related to the error is a transmission or print image file, so the process proceeds to step S1102, and a serviceman call error (disk error) and “Power OFF / ON Message "and prompt the user to turn the power off / on. When the user instructs to turn off the power, the power is turned off.
[0066]
On the other hand, in step S1101, if it is not an error event from each application but an error at the time of file reading by the UI 901, the process proceeds to step S1103, and it is determined whether or not there is a display image reading error from the file type read from the HDD. If it is a display image read error, the file type is a display image file, and the process advances to step S1104 to display a message “Preview image cannot be displayed”. In this case, it is not necessary to treat as a serious error such as turning off / on the power. If it is determined in step S1105 that there is no display image read error, the process advances to step S1105 to display other serviceman error (others). In this case, the user is prompted to turn off / on the power supply as a serious serviceman error. When the user instructs to turn off the power, the power is turned off.
[0067]
As described above, according to the present embodiment, in order to transmit / print or preview an image stored in a hard disk (HDD), a file in a corresponding format is read and an error occurs. By changing the error message to be displayed according to the type, if a non-serious error such as an error in reading a preview image file occurs, the user can continue the process.
[0068]
If an error occurs, if the file is an image transmission / print file, error control is performed by turning the power on / off. If the file display process, only error display is performed. It is possible to improve and minimize a decrease in processing efficiency of the apparatus at the time of error.
[0069]
In the present embodiment, the error control is changed based on the file type, but the present invention is not limited to this, and the process in which a file read error occurs regardless of what the file type is. It may be determined whether the process is a transmission process, a display process, or a printing process, and the error control may be changed directly according to the determination result. The control in this case can be explained in the same manner as the flowchart described above.
[0070]
In the present embodiment, control is performed so that the processing of the flowchart of FIG. 11 is started when a file error occurs. However, the present invention is not limited to this, and when the file is not read properly. Widely applicable. In this embodiment, error display is performed as an error notification method. However, the present invention is not limited to this. For example, error notification by voice notification or print notification by a printing unit is possible. Needless to say, this is applicable even in cases.
[0071]
Even if the present invention is applied to a system composed of a plurality of devices (for example, a host computer, an interface device, a reader, a printer, etc.), it is applied to an apparatus (for example, a copier, a facsimile machine, etc.) composed of a single device. It may be applied.
[0072]
