03, image storage unit 304, smoothing unit 305, γ correction unit 3
It is equipped with 06.

The original image supplied from the image reading unit 201 is, for example, 8-bit width brightness data. The log conversion unit 301 has a look-up table, and converts 8-bit width luminance data into 8-bit width density data based on the look-up table. Binarization unit 302
Converts the 8-bit width density data to 0 or 1
The binary density data expressed by is generated. This 2
By digitizing, the data amount of the density data can be reduced to 1/4. However, due to this binarization, the number of gradations of the image is changed from 256 gradations to 2 gradations, and therefore, the deterioration of an image having a halftone like a photographic image is generally remarkable. Therefore, it is preferable that the binarization unit 302 perform binarization using the pseudo halftone expression.

In this example, an example in which the binarization unit 302 generates binary data of pseudo halftone expression by the error diffusion method will be described. The error diffusion method uses the input data (in this example, l
The pixel value in the data supplied from the og conversion unit 301) is compared with a predetermined threshold value. If the pixel value is larger than the predetermined threshold value, the value of the output data (binary data) is set to 2
55 (1), and when the pixel value is less than or equal to a predetermined threshold value, the output data (binary data) is binarized with the value of 0, and then the pixel value and the binarized value are This is a method of distributing the difference to surrounding pixels as an error. The error is distributed by multiplying the error by a weighting coefficient on a matrix prepared in advance and adding it to surrounding pixels. As a result, the average value of the densities of the entire image can be saved, and the halftone can be represented in a pseudo manner by the binary pixels.

The binary data generated by the binarizing unit 303 or the expanding unit 209 is supplied to the data managing unit 303. In the data management unit 303, the control unit 20 shown in FIG.
Under the control of 5, the input binary data is managed using the image storage unit 304 such as a hard disk. For example, the data management unit 303 temporarily stores the input binary data in the image storage unit 304, sequentially reads the stored binary data according to the mode set via the operation panel 190, and then performs the smoothing unit. Supply to 305.

For example, when the sort mode is set by the operation panel 190, the control unit 205 causes the circulating automatic document feeder 180 to sequentially read the originals from the last page to the first page of the original stack. Then, under the control of the control unit 205, the data management unit 303 sequentially stores the binary data regarding the read document in the image storage unit 304, sequentially reads the binary data in page units, and supplies the binary data to the smoothing unit 305. Repeat for the set number of copies (this function is called electronic sorter). With this electronic sorter, it is possible to realize the same function as that of a sorter having a plurality of bins for loading the copied transfer sheets. Further, since the read original image is temporarily stored in the image storage unit 304, the original need only be read once, and when an error such as a paper jam occurs, the trouble of reading the original again is released.

The smoothing unit 305 converts the 1-bit width data (binary data) supplied from the data management unit 303 into image data having a pixel value of 0 or 255. And
The value of this image data is replaced with a weighted average value based on the sum of the coefficients of a preset matrix and the density values of neighboring pixels. As a result, the binary data is converted into multivalued data according to the density value of the neighboring pixels, and the image quality closer to the original image can be reproduced. The smoothed image data is input to the γ correction unit 306. The γ correction unit 306 converts the density of the input image data so as to correct the printer characteristics by referring to the look-up table when outputting the image data. Note that as many lookup tables as the number corresponding to the density set by the copy density key on the operation panel 190 are prepared.
