Below, these processes of this embodiment will be specifically explained with reference to the circuit diagram of FIG. 12 and the timing chart of FIG. 13.

That is, from the selectors 4253R14253G, 4253B to the FIFO memories 4050R14050G, 4050B
Prior to data transfer to, the effective area in the main scanning direction of the area specified by the digitizer 16 is written to the comparators 4232 and 4233 by the CPU bus 961O.

The comparator 4232 is set with a start address in the main scanning direction of the area designated by the digitizer 16, and the comparator 4233 is set with a stop address.

In addition, the sub-scanning direction of the area specified by the digitizer 16 is controlled by the selector 4213 to select the CPU bus 9610 side to make it valid, and write "ON data" to the valid area of the area specified by the RAM 4212 to make it invalid. In the area “
Write “l”.

For scaling processing in the main scanning direction, a scaling factor is set in the rate multiplier 4234 via the CPU bus 961O. In addition, the magnification processing in the sub-scanning direction is performed in RAM4.
This is possible depending on the data written to 212.

FIG. 13 is a timing chart when trimming processing is performed. As mentioned above, when storing only the area specified by the digitizer 16 in the memory (trimming processing), the trimming position in the main scanning direction is set in the comparators 4232 and 4233, and the trimming position in the sub-scanning direction is set in the selector 4213. is placed on the CPU bus 9610 side, and written to the RAM 4212 by the CPU.

Below, as a specific example, the trimming position is 1 in the main scanning direction.
A case where the number is 000 to 3047 and 1000 to 5095 in the sub-scanning direction will be explained.

The trimming section signal 9100 in the main scanning direction is H5YN
The counter 4230 operates in synchronization with CIN, 9452 and CLKIN 9456, and this counter output 9103 is t.
ooo, the output of the comparator 4232 becomes “
1", and the output Q of the flip-flop 4235 becomes "l".
Then, when the counter output 9103 becomes 3047, the output of the comparator 4233 becomes "l" and 7,
The output of the flip-flop 4235 changes from “1” to “0”.
''. Also, in the timing chart of Fig. 13,
Rate multiplier 423 is used because it is processed at the same size.
4 output is “1”, trimming section signal 9100
FIFO memory 4050R14050G, 40
The color image information input to 50B from address 1000 to address 3047 is stored in FIFO memories 4050R and 405.

VSYNCIN, 9455. H5YNCIN, 9452
The 0 interval signal 9104 which outputs the interval signal 9104 synchronized with the signal 9102 from the RAM 4212 is synchronized with the signal 9102 by the flip-flop 4211,
The image information stored in 14050G and 4050B is output only in the section where the trimming signal 9101 is "O" (n
”~m′).

In the above description, only the trimming process has been described, but the scaling process can be performed simultaneously with the trimming. For scaling in the main scanning direction, a scaling factor is set in the rate multiplier 4234 via the CPU bus 9610. Further, in the sub-scanning, magnification processing can be performed by data written to the RAM 4212.

FIG. 14 is a timing chart showing the operation when trimming processing and 50% scaling processing are performed. FIG. 14 shows that the image data from the selectors 4254R1G and 4254R1B are scaled down by 50% and stored in the FIFO memory 405.
An example is shown in which data is transferred to 0R14050G and 4050B.

Next, FIFO memory 4050R14050G, 4050
Transfer of image data from B to memories 406OR, 4060G, and 4060B is performed by counter O (4080-0) and control line 9101.

Control line 9101 is FIFO memory 4050R14
050G, 4050B read enable signal,
and an enable signal for counter 4080-0 and memory 4060R.

It is also a write enable signal for 4060G and 4060B.

When the control line 9101 is “o”, the FIFO memory 4
The image data read from 05OR14050G and 4050B is sent to the tri-state buffer 909OR190.

Image data 9 input to 4060G and 4080B
090R19090G and 9090B are stored.

Note that since the memory capacity in this embodiment is 1M bytes for each color, the image data in the reading area in FIG.
By reducing the read image data by 0%, the read image data is converted to data of the maximum capacity of the memory of the image storage device 3 and is stored.

In one or more embodiments, the CPU 4360 calculates the effective area from information on the area specified by the digitizer 16 of the A3 document, and calculates the effective area using the comparators 4231 to 4233. Set data corresponding to rate multiplier 4234 and RAM 4212.

In this embodiment, since the data capacity of the read image was larger than the image memory capacity, a reduction process was performed to convert the data to a storable capacity, and then the data was stored in the image memory. However, if the data capacity of the read image is smaller than the image memory capacity, the CLR signal 917 in FIG.

Furthermore, the write data to the RAM 4212 is set to "0" for all image valid areas and "1" for the other areas, and set to the same size.

In addition, in order to store the read image in the memory while maintaining its aspect ratio (vertical/horizontal ratio), the CPU 4360 first performs zero-order processing to calculate the effective number of pixels "X" from the area information sent from the digitizer 16.

In the image layout shown in FIG. 20, "Image 3" is an image obtained by rotating the image from the color reader 1 by 90 degrees.

This image rotation process is performed in the following steps.

First, the memory 406 is controlled by the DMAC (direct memory access controller) 4380 in FIG.

It is sent to the masking/black extraction/UCR circuit 4120 via R14110G and R14110B, where it becomes a frame-sequential color signal 9210. This frame sequential signal 921O is parallelized by the selector 4130, divided for each pixel, and sent to the FIFO memory 4140-0.4140-1. Then, the expansion from the system controller 4210
When the operation permission signal 9320-0.9320-1 to the interpolation circuit 4150-0.4150-1 is enabled, the expansion/interpolation circuit 4150-0.4150-1 enables the FIFO read signal 9280-O19280-1, Start read control.

FIFO memory 4140-0.4140-1 starts transferring image data to enlargement/interpolation circuit 4150-0.4150-1 in response to signal 9280-0.9280-1. And this enlargement/interpolation circuit 4150-0.4

The subsequent processing up to the connector 4550 is the same as described above, so the explanation will be omitted.

Next, with reference to FIG. 22, the timing of the "see 2" line shown in FIG. 20 will be explained.

The processing from the image memories 4060R, 4060G, and 4060B to the enlargement/interpolation circuits 4150-1 and 4150-2 is the same as described above.

As shown in Fig. 20, in the “J12” line, “Image 1
” and “Image 2” overlap. In this overlapping portion, it can be selected by a control signal 9340 from the system controller 421O whether to form one image, both images, or both images.

The specific control is the same as in the above case.

The signal from connector 4550 is connected to color reader l by a cable. Therefore, the video interface 101 of the color reader 1 selectively outputs the image signal 105 from the image storage device 3 to the printer interface 56 through the signal line path shown in FIG.

The video interface 101 of the video processing unit 12 processes the types of data (R, G, B)/(M,
C, Y, BK) according to the video interface 101
Select the processing method.

In this embodiment, since M, C, Y, and BK are output sequentially, the above operation is repeated four times in the order of M, C, Y, and BK to form an image.

That is, by first displaying the size of the recording paper on the monitor television 32, and inputting the layout position information of each image using the host computer 33 while viewing this display, it is possible to layout each image to be recorded on the color printer 2. It is.

At this time, image memory 406OR14G60G, 4060
The reading control of stored information from B to the color printer 2 and the recording control in the color printer 2 are the same as those in the above-mentioned embodiment, so the explanation will be omitted.

Description of Computer Interface> In the system of this embodiment, a host computer 33 is connected to the image storage device 3, as shown in FIG. Next, the interface between the device of this embodiment and the host computer 33 will be explained using FIG.

The interface with the host computer 33 is performed by a GPZB controller 4310 connected by a connector 4580. GPZB controller is CP
It is connected to the CPU 4360 via the U bus 9610, and can exchange commands and transfer image data with the host computer 33 according to a predetermined protocol.

Although detailed embodiments have been described above, the present invention is of course applicable not only to the above-mentioned color image forming system but also to monochrome printers and the like.

[Effects of the Invention] As explained above, according to the present invention, the information reproduced from the storage medium is stored only when the information is image information, and the rest is read and ignored. Even when various types of information are mixed and stored in the memory, images of types of information that are not originally reproduced will not be formed, and processing can be performed without confusion. Therefore, even a storage medium that stores various types of information can be handled in the same way as a storage medium that stores only images, which has the effect of promoting the effective use of this type of storage medium.
