The CPU 214 controls the image processing unit 211 and the interface 213 according to the settings set on the operation unit 500. For example, when a copy mode in which the trimming process is performed by the operation unit 500 to perform copying is set, the image processing unit 211 performs the trimming process and transfers the image data to the printer unit 2. When the facsimile transmission mode is set on the operation unit 500, the interface unit 213 causes the core unit 10 to transfer image data and a control command corresponding to the set mode. Such a control program of the CPU 214 is stored in the memory 216, and the CPU 214 performs control while referring to the memory 216. The memory 216 is also used as a work area of the CPU 214.
[0020]

Then, the data is transferred to the facsimile unit 4, the file unit 5, and the network interface unit 7 via the interface 320. The code data representing the image input via the network interface unit 7 is transferred to the data processing unit 321 to determine whether the PD1 is 1IPS or PostScript, and the appropriate formatter unit 8 The data is transferred to the data processing unit 321 and then transferred to the facsimile unit 4 and the printer unit 2. The image data from the facsimile unit 4 is transferred to the data processing unit 321 and then to the printer unit 2, the file unit 5, and the network interface unit 7. The image data from the file unit 5 is transferred to the data processing unit 121 and then to the printer unit 2, facsimile unit 4, and network interface unit 7. The CPU 323 performs such control according to a control program stored in the memory 324 and a control command transferred from the reader unit 1. The memory 324 is also used as a work area of the CPU 323. In the network interface unit 7, a database called MIB (Management Information Base) is constructed, which communicates with a computer on a network via an SNMP protocol to enable printer management.
[0021]
As described above, it is possible to perform processing combining functions such as reading of a document image, printing of an image, transmission and reception of an image, storage of an image, input and output of data from a computer, and the like, centering on the core unit 10. .
[0022]
FIG. 5 is a block diagram illustrating a detailed configuration of the image processing unit 211.
[0023]
The image subjected to A / D conversion and shading correction by the A / D / SH unit 210 is input as B1ack luminance data, and sent to the 1 log conversion unit 250. The 1 log converter 250 stores 1UT for converting the input luminance data into the density data, and converts the luminance data into the density data by outputting a table value corresponding to the input data.
[0024]
Thereafter, the density data is sent to the binarization unit 251. The binarization unit 251 binarizes the multi-value density data, and the density value becomes “0” or “255”. The binarized 8-bit image data is converted into 1-bit image data of “0” or “1”, and the amount of image data stored in the memory is reduced.
[0025]
However, when the image is binarized, the number of gradations of the image is changed from 256 gradations to two gradations. Therefore, binarization of image data having a large number of halftones such as a photographic image generally significantly deteriorates the image. Therefore, it is necessary to perform pseudo halftone expression using binary data. For example, an error diffusion method is used as a method for pseudo-halftone expression using binary data. According to this method, when the density of a certain image is larger than a certain threshold value, it is determined that the density data is “255”, and when the density is less than a certain threshold value, the density data is “0”. Is a method of distributing the difference between the density data and the binarized data to surrounding pixels as an error signal. The distribution of the error is performed by multiplying a weight coefficient on a matrix prepared in advance by the error generated by the binarization, and adding the result to surrounding pixels. As a result, the density average value of the entire image is stored, and the halftone can be represented in a pseudo binary manner.
[0026]
The binarized image data is sent to the control unit 252. The bitmap image data obtained by expanding the PD1 from the computer is input from the core unit 10 and is already developed as binary image data by the 1IPS formatter unit or the PS formatter unit of the core unit 10. Sent to the unit 252.
[0027]
The control unit 252 stores an image via an A / D / SH or a bitmap image obtained by expanding the PD1 from the I / F 213 using a document read from the RDF or the platen glass according to a command from the main body. The image data is sequentially read from the image storage unit 255 or stored in the storage unit 255.
[0028]
The image storage unit 255 has a SCSI controller 256 and a hard disk 257 (memory), and writes image data to the hard disk according to a command from the SCSI controller. For example, a plurality of image data stored on a hard disk is printed in an order corresponding to an editing mode specified by an operation unit of a copying machine. For example, when the PD1 image sent from the first page is printed in the reverse order and electronically sorted, the bitmap images after the PD1 expansion of all the pages sent from the host are temporarily stored in the hard disk, and then the last page is first stored. The images are read from the hard disk in order toward the page and printed. This is repeated for the number of copies requested by the host, thereby realizing electronic sorting.
[0029]
Image data called from the image storage unit 255 and image data not stored in the image storage unit 255 are sent to the smoothing unit 253. The smoothing unit 253 first converts 1-bit data into 8-bit data, and sets the image data signal to “0” or “255”.
[0030]
The converted image data is replaced with a weighted average value obtained by summing the values obtained by multiplying the coefficients on the predetermined matrix by the density values of the neighboring pixels. As a result, the binary data is converted into multi-valued data in accordance with the density value of the neighboring pixels, and an image quality closer to the read image can be reproduced. The smoothed image data is input to the gamma correction unit 254. When outputting the density data, the γ correction unit 254 performs conversion using 1UT in consideration of the characteristics of the printer, and adjusts the output according to the density value set by the operation unit. As a result, the processed image is transferred to the printer unit 2 and printout is executed.
