The output of the input masking unit 602 is sent to the ACS count unit 603 and the graphic processor 151.

  FIG. 6 is a block diagram illustrating a detailed configuration of the ACS count unit 603.

  In FIG. 6, the ACS count unit 603 includes a filter 501, an area detection circuit 502, a color determination unit 503, a counter 504, and registers 507 to 510.

  ACS is a function for determining whether a document is a color document or a monochrome document. That is, color / monochrome determination is performed according to the number of pixels that are equal to or greater than a threshold value for which the saturation of each pixel is obtained. However, even in the case of a black and white image, due to the influence of MTF or the like, when viewed microscopically, there are a large number of color pixels around the edge, and it is difficult to simply perform ACS determination on a pixel basis. Various methods are provided for this ACS. However, in this embodiment, since it is not particular to a method for performing ACS, a description will be given by a very general method.

  As described above, even in a black and white image, there are many color pixels when viewed microscopically. Therefore, whether or not the pixel is really a color pixel is determined based on information on surrounding color pixels with respect to the target pixel. There is a need. The filter 501 is used to make the above-described determination, and has a FIFO structure for referring to the peripheral pixel with respect to the target pixel.

  The area detection circuit 502 creates an area signal 505 to which ACS is applied based on the values set in the registers 507 to 510 from the main controller 111 and the video control signal 512 sent from the reader unit 200. Based on the region signal 505 to which ACS is applied, the color determination unit 503 refers to the peripheral pixel stored in the memory in the filter 501 for the target pixel, and determines whether the target pixel is a color pixel or a monochrome pixel. The counter 504 counts the number of color determination signals output from the color determination unit 503.

  The main controller 111 determines an area to be subjected to ACS with respect to the document reading range, and sets the area in the registers 507 to 510. In this embodiment, the reading range is determined independently of the original. Further, the main controller 111 compares the value of the counter 504 that counts the number of color determination signals in the area to which ACS is applied with a predetermined threshold value, and determines whether the document is a color document or a monochrome document. .

  In the registers 507 to 510, the position where the color determination unit 503 starts the determination and the position where the determination ends are set in each of the main scanning direction and the sub-scanning direction based on the video control signal 512 sent from the reader unit 200. Keep it. In the present embodiment, the position for starting the determination and the position for ending the determination are set to be about 10 mm smaller than the actual size of the original.

  FIG. 7 is a block diagram illustrating a detailed configuration of the printer image processing unit 153.

  In FIG. 7, the printer image processing unit 153 includes a LOG conversion unit 701, a moire removal unit 702, a UCR (Under Color Removal) / masking unit 703, a γ correction unit 704, a filter unit 705, and an output switching unit 706.

  An image signal (RGB signal) sent from the graphic processor 151 to the printer image processing unit 153 via the printer bus 156 is first input to the LOG conversion unit 701. The LOG converter 701 converts RGB signals into CMY signals by LOG conversion. Next, the moire removing unit 702 removes moire from the CMY signal. The UCR / masking unit 703 generates a CMYK signal from the CMY signal that has been subjected to moire removal processing by UCR processing, and corrects it to a signal that matches the print output of the printer unit 300 by masking processing.

  The γ correction unit 704 performs density adjustment on the signal processed by the UCR / masking unit 703, and the filter unit 705 performs smoothing processing or edge processing on the signal after density adjustment. By switching the output signal of the filter unit 705 by the output switching 706, image data is temporarily stored in the DRAM 154 for each CMYK image in order to correct the distance between the photosensitive drums 325 to 328, and the distance between the photosensitive drums 325 to 328 is changed. The corrected image data is output to the printer unit 300 via the connector 155.

  FIG. 8 is a block diagram showing a detailed configuration of the graphic processor 151.

  In FIG. 8, a graphic processor 151 includes an image rotation unit 801, an image scaling unit 802, a color space conversion unit 803, an LUT (Look Up Table) 804, an image binarization unit 805, a scanner input unit 806, and a printer output unit 807. , A DRAM controller 808, a crossbar switch 809, an input I / F 810, and an output I / F 811.

  The DRAM 152 is used as a temporary work area for each module of the graphic processor 151 via the DRAM controller 808. A work area is statically assigned to each module in advance so that the work area of the DRAM 152 used by each module of the graphic processor 151 does not compete. The graphic processor 151 is connected to the bus controller 113 of the main controller 111 via the I / F 150, and data transfer between the graphic processor 151 and the DRAM 122 is controlled by the bus controller 113 and DMA-transferred.

  The bus controller 113 performs control for setting a mode and the like for each module of the graphic processor 151, and timing control for transferring image data to each module. The input I / F 810 inputs the image data input from the I / F 150 to the crossbar switch 809. The format of image data input from the I / F 150 is binary raster image data, multi-value raster image data, JPEG compressed data, or the like. In the case of JPEG compressed data, it is converted into raster image data by the input I / F 810 and output to the crossbar switch 809.

  The output I / F 811 outputs the image data input from the crossbar switch 809 to the I / F 150. The format of the image data input from the crossbar switch 809 is raster image data, but it is also possible to perform JPEG compression by the output I / F 811 and output the data to the I / F 150.

  First, a processing procedure in the image rotation unit 801 will be described.

  The CPU 112 of the main controller 111 makes settings for image rotation control to the bus controller 113. With this setting, the bus controller 113 performs settings necessary for image rotation (for example, image size, rotation direction / angle, etc.) to the image rotation unit 801 via the I / F 150. After performing the necessary settings, the CPU 112 permits the bus controller 113 to transfer image data again. In accordance with this permission, the bus controller 113 starts transferring image data from the DRAM 122 or a device connected via each I / F.

  Here, the size of the image to be rotated by the image rotation unit 801 is 32 pixels × 32 lines, and when transferring image data on the image bus, 24 bytes (1 pixel for 8 bits for each of RGB) is used. Assume that image data transfer as a unit is performed.

  In order to obtain an image of 32 pixels × 32 lines, it is necessary to transfer unit image data 32 × 32 times, and it is necessary to transfer image data from discontinuous addresses. The image data transferred by the discontinuous addressing is written in the SRAM 134 so as to be rotated at a desired angle at the time of reading. If the image rotation direction is, for example, 90 ° counterclockwise rotation, the transferred image data is written in the Y direction. The image is rotated by reading in the X direction at the time of reading.

  The image rotation unit 801 reads image data from the DRAM 152 by the above-described reading method after image rotation (writing to the DRAM 152) of 32 pixels × 32 lines is completed, and transfers the image to the bus controller 113. The bus controller 113 that has received the rotated image data transfers the data to each device on the DRAM 122 or the I / F with continuous addressing.

  The series of processing described above is repeated until there is no processing request from the CPU 112 of the main controller 111 to the graphic processor 151 (until processing of the necessary number of pages is completed).

  Next, a processing procedure in the image scaling unit 802 will be described.

  The CPU 112 of the main controller 111 makes settings for image scaling control to the bus controller 113. With this setting, the bus controller 113 makes settings necessary for image scaling (magnification in the main scanning direction / sub-scanning direction, image size after scaling, etc.) to the image scaling unit 802 via the I / F 150. Do. After performing the necessary settings, the CPU 112 permits the bus controller 113 to transfer image data again.

  Next, the operation of the multifunction machine of the present embodiment will be described with reference to the flowcharts of FIGS.

  FIG. 31 is a flowchart showing the PDL image output process of the multifunction machine.

  In FIG. 31, in step S5001, when a PDL image is printed out from the multifunction device, the user performs print settings for a PDL image output job on the PC 401. The contents of the print setting parameters are the number of copies to be printed, paper size, distinction between single-sided / double-sided printing, page output order, sort output, presence / absence of stapling, and the like.

  In step S5002, the user gives a print instruction on the PC 401. Along with the print instruction, the driver software installed on the PC 401 converts the code data on the PC 401 to be printed into so-called PDL data, and the PDL data is set together with the print setting parameters set in step S5001 in the network 400. To the main controller 111 of the controller unit 110 of the multifunction peripheral.

  In step S5003, the CPU 112 of the main controller 111 of the controller unit 110 develops (rasterizes) the PDL data received via the connector 126 and the network controller 125 into image data based on the print setting parameters. The development of the image data is performed on the DRAM 122. When the development of the image data is completed, the process proceeds to step S5004.

  In step S5004, the CPU 112 of the main controller 111 transfers the image data developed on the DRAM 122 to the graphic processor 151.

  In step S5005, the graphic processor 151 performs image processing on the image data independently of the print setting parameters. For example, when the paper size specified by the print setting parameter is A4 and the paper feed unit 360 of the printer unit 300 has only A4R paper, the graphic processor 151 rotates the image by 90 degrees. Thus, it is possible to perform print output according to the paper to be printed. When the image processing of the image data is completed, the process proceeds to step S5006.

  In step S5006, the graphic processor 151 transfers the image data after image processing to the main controller 111. The CPU 112 of the main controller 111 stores the transferred image data on the DRAM 122.

  In step S5007, the CPU 112 of the main controller 111 transfers the image data on the DRAM 122 to the printer unit 300 at an appropriate timing while controlling the printer unit 300 via the graphic processor 151, the printer image processing unit 153, and the connector 155. To do.

  In step S5008, the CPU 112 of the main controller 111 controls the printer unit 300 via the connector 155 to print out image data. When the transfer of the image data is completed, that is, when the PDL job is finished, the print output is finished.

  FIG. 32 is a flowchart showing copy image output processing of the multifunction machine.

  In FIG. 32, in step S6001, when a copy image is printed out from the multifunction device, the user performs copy settings for a copy image output job on the operation unit 180 of the multifunction device. The contents of the copy setting parameters are the number of copies, paper size, distinction between single-sided copy / double-sided copy, enlargement / reduction ratio, sort output, presence / absence of stapling, and the like.

  In step S6002, when the user gives a copy start instruction on the operation unit 180, the CPU 112 of the main controller 111 of the controller unit 110 controls the reader unit 200 via the connector 160 to perform an image reading operation of a document. First, the document feeder unit 250 of the reader unit 200 feeds the documents placed on the document stacking unit one by one onto the platen glass 211, and simultaneously detects the size of the document. Image data is read by exposing and scanning the document based on the detected size of the document. Image data read from the document is compressed in an image format designated by the graphic processor 151 and stored in the DRAM 122.

  In the conventional copying machine, the scaling process in the sub-scanning direction is performed by changing the moving speed of the optical unit 213 according to the setting of the enlargement / reduction ratio of the copy setting, that is, according to the scaling ratio in the sub-scanning direction. It was realized. In contrast, in the MFP according to the present embodiment, image data is always read at the same magnification (100%) regardless of the setting of the enlargement / reduction ratio of the copy setting, and the scaling process is performed in the main scanning direction and the sub-scanning direction. Both scanning directions are performed by the graphic processor 151 described later.

  In step S6003, the CPU 112 of the main controller 111 transfers the image data on the DRAM 122 to the graphic processor 151 via the bus controller 113.

  In step S6004, the graphic processor 151 performs image processing based on the copy setting parameters. For example, when the enlargement ratio is set to 400%, the image scaling unit 802 which is a module in the graphic processor 151 is used to perform scaling processing in both the main scanning direction and the sub-scanning direction. When the image processing of the image data is completed, the process proceeds to step S6005.

  In step S6005, the graphic processor 151 compresses the image data after image processing in the designated image format and transfers the compressed image data to the main controller 111. The CPU 112 of the main controller 111 stores the transferred image data on the DRAM 122.

  In step S6006, the CPU 112 of the main controller 111 converts the image data stored on the DRAM 122 into a file in a designated file format, and transfers the filed image data to the HD drive 132 via the HD controller 131. The image data read from the document is stored in the HD of the HD drive 132.

  The operations in steps S6001 to S6006 are repeated as long as a document exists in the document feeding unit 250.

  In step S6007, the CPU 112 of the main controller 111 transfers the image data on the DRAM 122 to the printer unit 300. At this time, if the image data file to be printed does not exist on the DRAM 122, the image file is read from the HD drive 132 and stored in the DRAM 122. The CPU 112 of the main controller 111 transfers the image data on the DRAM 122 to the printer unit 300 at an appropriate timing while controlling the printer unit 300 via the graphic processor 151, the printer image processing unit 153, and the connector 155.

  In step S6008, the CPU 112 of the main controller 111 controls the printer unit 300 via the connector 155 to print out image data. When the transfer of all the image data is completed, that is, when the copy job is finished, the print output is finished.

  FIG. 33 is a flowchart showing scan transmission processing of the multifunction machine.

  In FIG. 33, in step S7001, when a scan image of a document is transmitted from the multifunction peripheral to the outside, the user performs scan job copy settings on the operation unit 180. The contents of the scan setting parameters include a transmission address, color document reading / monochrome document reading distinction, reading resolution, single-sided scanning / double-sided scanning distinction, and the like. In the present embodiment, it is assumed that multi-value image data is transmitted.

  In step S <b> 7002, when the user gives a scan start instruction on the operation unit 180, the main controller 111 of the controller unit 110 controls the reader unit 200 via the connector 160 to perform a document image reading operation. First, the document feeder unit 250 of the reader unit 200 feeds the documents placed on the document stacking unit one by one onto the platen glass 211, and simultaneously detects the size of the document. Image data is read by exposing and scanning the document based on the detected size of the document. The read image data is compressed in an image format designated by the graphic processor 151 and stored on the DRAM 122.

  In the present embodiment, it is assumed that image data is always read at 600 dpi regardless of the resolution setting of the scan setting, and resolution conversion is performed by the graphic processor 151 described later in both the main scanning direction and the sub-scanning direction.

  In step S7003, the CPU 112 of the main controller 111 transfers the image data on the DRAM 122 to the graphic processor 151, and performs image processing such as image rotation, resolution conversion, and color space conversion based on the scan setting parameters. The graphic processor 151 transfers the image data after image processing to the main controller 111, and the CPU 112 of the main controller 111 stores the transferred image data on the DRAM 122.

  In step S7004, the CPU 112 of the main controller 111 checks whether the destination at the time of scan transmission is an email transmission destination. If it is determined that the destination is not email transmission, the CPU 112 proceeds to step S7005 and determines to perform email transmission. If yes, the process proceeds to step S7007.

  In step S7005, the CPU 112 of the main controller 111 converts the image data into a file based on the determination in step S7004 that the e-mail transmission is not performed. That is, the CPU 112 of the main controller 111 converts the image data stored in the DRAM 122 into a file in a designated file format, and transfers the filed image data to the HD drive 132 via the HD controller 131, thereby The image data read from is stored in the HD drive 132.

  In step S7006, the CPU 112 of the main controller 111 sends image data via the network controller 125 and the LAN 1010 to the e-mail server 1004 when the transmission address is e-mail, for example, and to the database server 1002 when the transmission address is e.g. Send. When the transmission address is set in the printer unit 300, the CPU 112 of the main controller 111 controls the printer unit 300 via the graphic processor 151, the printer image processing unit 153, and the connector 155 at an appropriate timing. The image data on the DRAM 122 is transferred to the printer unit 300.

  In step S7007, the CPU 112 of the main controller 111 compares the image data size on the DRAM 122 with the upper limit set in the user mode from the operation unit 180 based on the determination that the e-mail transmission is performed in step S7004. . If the image data size is less than or equal to the upper limit value, the CPU 112 of the main controller 111 proceeds to step S7005 and transmits the image data as it is. If the image data size exceeds the upper limit value, the process proceeds to step S7008.

  In step S7008, the CPU 112 of the main controller 111 transfers the image data on the DRAM 122 to the graphic processor 151, and the image scaling unit 802 lowers the resolution according to the image data size. For example, the image scaling unit 802 is set so that the resolution is lowered when the image data size greatly exceeds the upper limit value, and the resolution is slightly lowered when the image data size slightly exceeds the upper limit value. .

  In step S7009, the CPU 112 of the main controller 111 sets the compression rate of the output I / F 811 to be higher than the setting of step S7002, and stores the image data with the changed resolution and compression rate in the DRAM 122. Return to step S7007.

  In step S7007, the CPU 112 of the main controller 111 compares the size of the image data stored again in the DRAM 122 with the upper limit value. If the size is larger than the upper limit value, the processing of step S7008 and step S7009 is repeated again.

  When the transmission of the image data from the multifunction device to the outside of the multifunction device is completed, the scan transmission process is terminated.

  FIG. 34 is a flowchart illustrating processing for returning from the sleep state of the multifunction peripheral (power control process), which is characteristic processing in the multifunction peripheral according to the present embodiment.

  34, in step S8001, the CPU 112 of the main controller 111 of the controller unit 110 determines whether or not the multifunction device is in a sleep state. If the multifunction device is determined not to be in a sleep state, the various screens of the operation unit 180 are displayed. If it is determined that the user's desired operation via the device can be accepted and the MFP is in the sleep state, the process proceeds to step S8002.

  In step S8002, the CPU 112 of the main controller 111 displays a mode selection screen (not shown) on the operation unit 180 upon determining that the multifunction device is in the sleep state, and indicates that the multifunction device is in the sleep state. To inform. When the user wants to return the multifunction device from the sleep state to the sleep release state, the user presses a sleep release button (not shown) provided on the operation unit 180.

  Note that the means for returning from the sleep state to the sleep release state is not limited to the dedicated sleep release button, but buttons and soft switches for functions other than the sleep release, such as a power saving button and a soft switch for power supply. You may be the structure used together.

  In step S8003, the CPU 112 of the main controller 111 executes a predetermined mode (a function accompanied by a printing operation) from the user on the mode selection screen on which a mode selection key such as copy / SEND / FAX transfer is displayed on the operation unit 180. Mode) to determine whether a selection has been made. If the user selects a predetermined mode, the process proceeds to step S8004. If the user does not perform a predetermined mode selection, the process proceeds to step S8005. In this case, the user presses one of the mode selection keys such as copy / SEND / FAX transfer on the mode selection screen.

  In step S8004, the CPU 112 of the main controller 111 prints the mode selected by the user on the mode selection screen like a copy function for printing an image read from a document by the reader unit 200 onto a sheet by the printer unit 300, for example. If it is determined that the mode is to execute a function that involves an operation, the printer unit 300 is released from the sleep state and the printer unit 300 is turned on (supplied).

  In step S8005, the CPU 112 of the main controller 111 determines whether the mode selected on the mode selection screen by the user is, for example, a SEND function for distributing data to an output destination or a communication destination, or FAX for transmitting an image read from a document. If it is determined that the mode is a mode that executes a function or a function that does not involve a printing operation, such as a box storage function that stores an image read from a document on a hard disk, the printer unit 300 is not turned on (supplied). , Perform the desired operation.

  As described above, according to the present embodiment, the CPU 112 of the main controller 111 of the controller unit 110 allows each function (copy) of the multifunction device when the operation is not performed for a predetermined set time in the power supply state of the multifunction device. Functions that can be used when canceling the sleep state that gradually turns off the power to operate the function, FAX transmission function, data distribution function, box storage function) If the selected function is a function involving a printing operation, the printer unit 300 is turned on. If the selected function is not a function involving a printing operation, the printer unit 300 is not turned on. Thus, power saving can be improved by restricting power supply to modules (for example, a printer unit) that are not used in processing desired by the user (for example, FAX transmission processing, data distribution processing, box storage processing, etc.). it can.
