DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram for explaining the configuration of an image processing apparatus showing an embodiment of the present invention, which corresponds to the case of being applied to a digital copying machine, for example.

The original is illuminated by an exposure lamp (not shown), and the reflected light is reflected by a CCD image sensor (hereinafter simply referred to as CCD).
Read by 101) and the amplification circuit 1
In 03, it is amplified to a predetermined level. Here, the CCD image sensor 101 is driven by a CCD driver 102. The image signal amplified to a predetermined level is sampled and held at a predetermined signal level in a sample hold circuit (S / H) 104.

The sampled and held analog image signal is converted from an analog signal to a digital signal in the A / D converter 105 and sent to the black correction / white correction circuit 106. The black correction white correction circuit 106 corrects the dark output level of the CCD and the sensitivity variations of the optical system and the sensor due to the white level. The corrected image information is subjected to various editing processes such as scaling, shadowing, contouring, italicization, negative / positive conversion, netting, netting, and moving, which are processes peculiar to the digital copying machine, in the image processing unit 107.

Then, in the control unit 13, the internal CPU 22 executes the program of the ROM 24 storing the control program on the RAM 23 used as a work area. Reference numeral 25 is an I / O port for inputting / outputting data to / from the outside.

Reference numeral 108 denotes a multi-valued image memory, which stores image information that has been subjected to image processing by the image processing unit 107 and sends image information from the image memory 108 to the image processing unit 109. The image processing unit 109 also synthesizes multivalued and multivalued images.

After performing various image processing, the D / A converter 1
The digital image signal is again converted into an analog image signal by 10, the level of the analog image signal is modulated into a pulse width by the pulse width conversion circuit 111, and the laser section 112 is operated.
Is written on a drum or the like which is a photoconductor, and although not described, it is copied by an electrophotographic process. In addition, 113 is a counter and 167 is a communication controller.

Although the embodiments of the present invention have been described with respect to a digital copying machine, in an apparatus for reading an image information by an optical image pickup device such as CCD 101 and forming an output image by a semiconductor laser using an electrophotographic process, It is necessary to finally correct the luminance information read from the CCD 101 according to the output control of the printer.

Normally, the original document density and the reflected light amount of the original document have a logarithmic relationship, and the output of the image pickup device is proportional to the light amount. Therefore, in order to obtain the output proportional to the original document density, it is necessary to perform inverse logarithmic correction.

This correction is called log conversion, and the log conversion is included in the image processing unit 107 in this embodiment. Also,
In addition to this, since the density range of the original document is larger than the density range that can be reproduced by the printer, it is necessary to convert the density range.

Further, a desired image may be obtained as a result by performing different density conversion depending on the type of the original (for example, a character original or a photographic original). ). The γ correction is performed by the image processing unit 109 in this embodiment, and this embodiment is characterized in that this table is switched for each document. An example of table data for γ correction will be described with reference to FIG.

FIG. 2 is a characteristic diagram showing an example of the γ conversion table data in the image processing unit 107 shown in FIG. 1, where the horizontal axis is the input image density information and the vertical axis is the output image density information.

2B is a linear table, and FIG. 2A is a non-linear table.

In the table of FIG. 2A, the dynamic range of the intermediate level portion of the input image is widened and the density reproduction range of the printer is small, so such a table is usually used.

FIG. 3 is a block diagram showing an example of the γ table data shown in FIG. In FIG. 3, 16 Kbit
It is composed of a ROM, but this is RA depending on the application.
It is possible to configure by M or RAMs of different sizes.

Reference numeral 3-15 indicates a Laplacian matrix subjected to the sharpening process, and the center is the pixel of interest. Sharpening by Laplacian can be explained by the following formula (1). f (i, j) -f (i, j) = 5f (i, j)-* f (i-1, j) + f (i, j-1) -f (i, j-1)
+ f (i + 1, j) * (1) where * is a multiplication coefficient.

That is, a clear image can be obtained by subtracting the blurred image (Laplacian * f (i, j)) from the image f (i, j).

In the above embodiment, the Laplacian calculation is performed by forming a matrix with DFFs 3-5 to 3-7 as a circuit block for realizing the above expression (1).

Here, the multiplier 3-9 outputs (i, j + 1),
The multiplier 3-10 is (i-1, j), the multiplier 3-11 is (i, j), the multiplier 3-12 is (i + 1, j), and the multiplier 3-13 is (i, j-1). ) Will be shown.

Further, 3-18 is a selector, and 3-1
Reference numeral 7 is a select signal of the selector 3-18. Normally, the select signal 3-17 is LOW, and the sharpening process can be turned ON / OFF. Reference numeral 3-16 is a select output.

FIG. 5 is a diagram showing an address space of the image memory 108 shown in FIG.

As shown in the figure, the image memory 108 is connected to the counter 113, and the counter output has 13 bits each, and these are input to the addresses A0 to A12 and A13 to A25 of the memory 108. Therefore, the H direction is from 0 to 8191, and the V direction is 0.
It is equivalent to the address space from the line to 8191 lines. Figure 5

Specifically, the start preset address 3128 in the H direction and the start preset address in the V direction are set at address 1120 (57). Next, set a reduction ratio of 33% (58),
Set the rotation direction at 0 ° (59), scan the original and perform negative / positive processing on the image memory, and the original original is 33%.
The reduced image is stored (60).

Then, in step (61), the test print switch is turned on to print out seven images including the original document stored in the image memory on A4 size output paper.

As described above, according to the second embodiment, the parameter setting for sequentially changing the parameters of the image processing unit (image processing unit 107) selected by the selection unit (by the selection instruction from the operation unit) is performed. Each image data image-processed by the image processing means selected by the image synthesizing means (image processing section 109) based on the parameters sequentially set by the means (CPU 22) is sequentially pasted on the image memory as one output image. It is possible to output a sample image for confirming the image processing effect of the selected image processing means by performing the composite combination.

As described above, the first aspect of the present invention
According to the invention, the image synthesizing means sequentially pastes and synthesizes each image data image-processed by each image processing means selected by the selecting means as one output image on the image memory. When storing the original document or one original document in a plurality of times in the image memory, the image processing can be changed for each time and the images can be pasted and stored in the image memory.

According to the second invention, the image for which the image synthesizing means is selected based on the parameters sequentially set by the parameter setting means for sequentially setting the parameters of the image processing means selected by the selecting means while varying the parameters. Since each image data image-processed by the processing means is sequentially pasted on the image memory as one output image and synthesized, a sample image for confirming the image processing effect by the selected image processing means can be output. .

Therefore, there is an effect that the sample images for confirming the image processing state can be collected and output as one sheet.
