[0034]
FIG. 2 is a block diagram showing a schematic configuration of the digital copying machine shown in FIG. 2, reference numeral 200 denotes a document; 201, an image reading unit; 202, an electronic sorter unit (corresponding to the electronic sorter device 53 in FIG. 1); 203, a printer unit (corresponding to the image forming unit 21 in FIG. 1); Denotes a CPU circuit unit, and 205 denotes an external I / F (interface) processing unit.
[0035]
The image reading unit 201 has a lens 201a (corresponding to the lens 7 in FIG. 1), a CCD image sensor 201b (corresponding to the CCD image sensor 8 in FIG. 1), and an analog signal processing circuit 201c. The CPU circuit section 204 has a CPU (Central Processing Unit) 204a, a ROM (Read Only Memory) 204b, and a RAM (Random Access Memory) 204c.
[0036]
Then, the image of the document 200 is formed on a CCD image sensor 201b via a lens 201a, and is converted into an analog electric signal by the CCD image sensor 201b. The converted image information is subjected to analog / digital conversion (A / D conversion) processing by the analog signal processing unit 206 to be digitized, and is subjected to shading correction processing (for example, the variation in reading accuracy of the CCD image sensor 201b that reads the original 200 and the variation in reading accuracy). After the light distribution characteristics of the original illumination lamps 9a and 9b in FIG. 1 are corrected, the magnification is changed, and the like, the data is input to the electronic sorter unit 202.
[0037]
The external I / F processing unit 205 expands image processing information input from an information processing device such as an external computer, and is input to the electronic sorter unit 202 as image data.
[0038]
The electronic sorter unit 202 performs necessary correction processing, smoothing processing, edge enhancement, and other processing and processing in an output system such as γ correction, and outputs the processed data to the printer unit 203.
[0039]
The printer unit 203 includes the exposure control unit 11 composed of a laser or the like described with reference to FIG. 1, the image forming unit 21, a transfer sheet transfer control unit, and the like, and an image is formed on the transfer sheet by an image signal input from the electronic sorter unit 202. Record
[0040]
The CPU circuit unit 204 controls the image reading unit 201, the electronic sorter unit 202, the printer unit 203, and the like, and totally controls the sequence of the present apparatus.
[0041]
FIG. 3 is a block diagram showing the configuration of the electronic sorter unit 202 in FIG. In the figure, 301 is a log conversion unit, 302 is a binarization unit, 303 is a control unit, 304 is an image storage unit, 305 is a smoothing unit, and 306 is a γ correction unit.
[0042]
The read image sent from the image reading unit 201 in FIG. 2 is input as Black (black) luminance data and sent to the log conversion unit 301. The log conversion unit 301 stores an LUT (logical unit table: logical device table) for converting input luminance data into density data, and outputs a table value corresponding to the input data. And converts the luminance data into density data.
[0043]
Thereafter, the density data is sent to the binarization unit 302, where the multi-valued density data is binarized, 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.
[0044]
However, when an image is binarized, the number of gradations of the image is changed from 256 gradations to two gradations. Therefore, when binarizing image data such as a photographic image, image deterioration is generally remarkable. Therefore, it is necessary to perform pseudo halftone expression using binary data. Here, an error diffusion method is used as a method for pseudo-halftone expression using binary data. According to this method, when the density of the image data is larger than a certain "threshold", the density data is "255". When the density of the image data is smaller than a certain "threshold", the value is "0". This is a method of binarizing assuming that the data is density data, and then distributing the difference between the actual 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 average density value of the entire image is stored, and the halftone can be represented in a pseudo binary manner.
[0045]
The binarized image data is sent to the control unit 303. The image data from the information processing device such as a computer input from the external I / F processing unit 205 is processed as binary image data by the external I / F processing unit 205, and thus is transmitted to the control unit 303 as it is. Can be
[0046]
The control unit 303 temporarily stores all the images of the original to be copied in the image storage unit 304 or sequentially reads out and outputs the image data from the image storage unit 304 according to a command from the main body.
[0047]
The image storage unit 304 has a SCSI controller and a hard disk (memory), and writes image data to the hard disk according to a command from the SCSI controller. The plurality of image data stored in the hard disk are output in an order according to the editing mode specified by the operation unit of the digital copying machine. For example, in the case of sorting, the document is read in order from the last page to the first page of the document bundle from the circulating automatic document feeder 51 in FIG. 1 and temporarily stored in the hard disk. Then, the image data of the document once stored is read from the hard disk in order from the last page to the first page, and this is repeated a plurality of times and output. Thereby, it can play the same role as a sorter having a plurality of bins. In addition, since the image can be stored, a plurality of copies can be printed without reading the document a plurality of times, and even when the printing operation is restarted due to a paper jam or the like, the image stored in the image storage unit 304 is stored. There is no need to read the data document.
[0048]
The image data read from the image storage unit 304 is sent to the smoothing unit 305. The smoothing unit 305 first converts 1-bit image data into 8-bit image data, and sets the image data signal to “0” or “255”.
[0049]
The image data converted into the 8-bit image data is obtained as a sum of multiplications of coefficients on a predetermined matrix and density values of neighboring pixels, and is replaced with a weighted average value. As a result, the binary image data is converted into multi-valued image data according to the density value of the neighboring pixels, and an image quality closer to the read image can be reproduced. The image data smoothed by the smoothing unit 305 is input to the γ correction unit 306. When outputting the density data, the γ correction unit 306 performs a conversion process using the LUT in consideration of the characteristics of the printer unit 203 in FIG. 2 and adjusts the output according to the density value set by the operation unit.

Next, the operation of the image processing apparatus according to the present embodiment will be described with reference to the flowchart in FIG. The process shown in FIG. 5 is performed by the CPU 204a of FIG. 2 reading out a control program stored in the ROM 204b and executing the control program in accordance with the control program.
[0056]
First, in step S501, the number of output sheets and the function to be used are selected, that is, a copy job is set. Next, in step S502, it is determined whether the copy has been started or not until the copy is started. When the copy is started, a series of printing operations such as scanning of the original, printing on paper, and storing image data in a storage medium are performed in step S503. Next, in step S504, it is determined whether or not the printing operation is stopped. If the printing operation is not stopped, the process returns to step S503 to perform the printing operation again. If the print job is stopped in step S504, the print job is ended if the reason for the stop is a normal job end. If the reason for the stop is not a normal end of the job but an abnormal stop, a message indicating the type of the error is displayed on the message display unit 601 of the operation unit in FIG.
[0057]
Next, in step S505, it is determined whether or not the type in which the printing operation has been stopped is capable of jam recovery. If the jam recovery is not possible, the printing operation is terminated. If jam recovery is possible, a message prompting whether to interrupt the job is displayed on the message display unit 601 of the operation unit in FIG. 4 in step S506, and it is determined whether to interrupt the job. If the job is not interrupted in step S506, a recovery process is performed in step S507, and the process returns to step S503 to perform printing again. If the job is to be interrupted in step S506, the current operation status of the job (the number of copies, the designated function, etc.) and the job interruption ID are stored in the RAM 204c in FIG. 2 in step S508. The job ID is an identifier for identifying a job, and is used when resuming. This is input by the user or issued by the image processing apparatus.
[0058]
Next, in step S509, the image processing apparatus is released and can be used by a third party. Next, in step S510, it is determined whether another job is to be performed. If another job is to be performed, the process returns to step S501 to set a copy job. If another job is not to be performed, it is determined in step S511 whether or not to restart the job. If the job is not to be resumed, the process returns to step S510 to determine whether another job is to be performed again. When resuming a job, the user is asked for the ID of the job to be resumed, so the user inputs his or her interrupted ID in step S512. When the correct ID is input, the operation status of the job interrupted in step S513 is displayed, and the number of image data stored up to the present is displayed. If the device has a large operation panel, the operability is further improved by displaying the image data stored last at this time. Next, it is determined in step S514 whether or not to start copying until the copying is started. If there is a document to be read at the time of resuming the job, the document is set in the circulating automatic document feeder 51 in FIG. 1 and the copy start key 504 in FIG. 4 is pressed. Returning, the printing operation is resumed, and if there is no original to be added, if the copy start key 504 in FIG. 4 is pressed as it is, the printing operation is resumed.
