Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image processing system that processes image information converted into electrical signals.

It is known to record an image based on an image signal obtained by photoelectric KM or to transmit this image signal to a remote location.

This mode is called pass mode.

The control related to the transmission of the image signal described above is executed by the CPU 32 in accordance with the operation command input by the operator using the keyboard 31.

FIG. 3 shows the 6'P detailed circuit arrangement of the switching device 9.

Cables that are the same as in FIG. 2 are given the same numbers.

, the microphone viewing film file 5, the high-speed printer 3 that inputs image signals from the control unit 1 and the switching device 9, the soft display 6, the small printer 7, the connection state with the control unit 1, and switches 51 to 54.61 to 63.71. The relationship between the operating states of ~74 is shown.

Note that the numbers in parentheses indicate image signal transmission cables. Further, each switch number indicates that the switch is in a closed state. Note that the switching device 9 can also be configured with a logic circuit.

The operation of the switching bag 'l119 will be explained. For example, switch 7
When 2.53 and 63 are in the closed state, the image signal from the document reader 2 is transmitted to the high-speed printer 3 via the switch 72, and operates as a digital copying machine. On the other hand, the iI! from the microfilm file 5 is sent via the switch 53! The Ii image signal is transmitted to the soft display 6. Further, the image signal from the control section 1 is transmitted to the small printer 7 via the switch 63.

In this way, by selectively operating the switches of the switching device 9, each input/output device can be arbitrarily connected, and
This system allows the system to effectively function as a display device, copying device, and file device. Furthermore, since it is possible to transmit a plurality of pieces of image information at the same time, it is possible to eliminate the inconvenience that the system is occupied by the transmission of a certain piece of image information and other input/output devices become inoperable. Furthermore, as mentioned above,
When performing simple close-up photography or display operations, image signals from the document reader 2 and the microphone film file 5 can be directly transmitted to the high-speed printer 3, the soft display 6, or the small printer 7 without going through the control section 1. (bus mode) achieves high-speed processing.

Next, Hara 41. CR image display based on image signals output from J reader 2 and microfilm file 5
The operation performed at T8 will be explained. This system uses a high-resolution CRT, and the amount of information that can be displayed is approximately 6 x 104 bits. However, for example, the document reader 2 can read a maximum of A3 size original f111, and when reading an A4 size document (210m x 297mm) at a resolution of 16 pet/ram, the total information is 106 bits out of 16 x 210 x 297. Become. Further, the image information from the microfilm file 5 is also in the same order. Therefore, the image of the yX reader 2 and the microfilm file 5 is stored in the RAM 3.
At the same time, when displaying on CI (, T8, it is necessary to compress the amount of information to, for example, 1/16 for CR and T display. This information amount compression operation is performed in parallel with the storage of .

FIG. 5 shows the configuration of the bit extraction circuit 38.

41 is a bus within the control unit 1. 44 is an extraction timing selection circuit which outputs a clock pulse CK according to a compression command from the CPU 32. A shift register 45 samples the image signal input from the input/output interface 7 ace 37 in accordance with the clock pulse CK from the extraction timing selection circuit 44, and stores the signal obtained by thinning out the image signal. 46 is a RAM, which takes in the data when the shift register 45 is full, and further transfers the compressed image signal to the bus 41 at a predetermined timing.
Output to. The input/output interface 7 ace 37 is the switching device 9
The image signal inputted from the bus 41 is outputted to the bus 41 for storage in the RAM 34, and is also supplied to the bit extraction circuit 38 at the same time. That is, the image signal output from the document reader 2 or the microfilm file 5 is stored in the RAM 3 in its original form.
Simultaneously with the storage operation in 4, the image signal reduction operation for CRT display is performed. Therefore, the input image signal is immediately displayed on the CRT.

FIG. 6 shows the operating state of the bit extraction circuit 38. The image signal is output line by line from the switching device 9 to the repeat bus 41 via the input/output interface 37, and is sent to the RAM 34.
be taken into account. FIG. 6(1) shows the timing at which the image signal is written from the input/output interface 37 through the bus 41 to the RAM 34, and the numbers 1 to 9 in the figure are the line numbers of the N-fold signal. As shown in the figure, a blank time T occurs from the output of the image signal of one line until the output of the image signal of the next line. The input/output interface 7 ace 37 converts the image signal input from the switching device 9 into a bit extraction circuit 38.
Also output to. The bit extraction circuit 38 performs the thinning operation of the image number η in accordance with the clock pulse CK from the extraction timing selection circuit 44 as described above. The example in FIG. 6 shows the operation when compressing the image signal to 1/16, that is, the input image signal is compressed at a ratio of 1 line to 4 lines.
That is, the image signal of 4N-1 lines is extracted, and the Il! of the extracted 4N-1 lines is further extracted. II image signal into 4 dots
It is extracted based on the percentage of dots.

FIG. 6(2) shows the llTl1 image %J number extracted at a ratio of 1 line to 4 lines. In addition, Fig. 6 (3) shows the extracted one-line image signal, and Fig. 6 (4)
indicates the image a signal of one line extracted at a ratio of 1 bit to 4 bits. In FIGS. 6(3) and 6(4), numbers 1 to 2 in the data indicate each bit number.

In this way, Ma extracted at a ratio of 1 in 4 lines
By further extracting 1 bit for every 4 bits of the doubled signal, the image signal inputted from the switching device 9 to the input/output interface 7 ace 37 can be compressed to 1/16.

The bits are extracted and the compressed image signal is stored in the RAM 4 in the first path 38.
Store one part in 6. And input/output interface 7 ace 3
7 to the RAM 34, from the RAM 46 via the path 41,
i(, write to AM43. Image signal 1 after compression processing
, 5' are smaller than the image signals written in the AM 34, so they can be effectively transmitted using the path 41 during this blank time T. In addition to outputting the compressed image signal for one line per blank time T, the compressed image signal may be divided into several times and transmitted to the CRT 1 (AM43).

The above operation of the bit extraction circuit 38 is controlled by the CPU 32. Further, the compression rate of the image signal is determined according to the image size of the image signal output from the input/output interface 7 ace 37. That is, when displaying the entire image on the display screen size of the CRT8, the i corresponding to the image to be displayed is
I! If the compression rate is determined according to the amount of Ii image signal + J, CR
The display screen of T can be displayed effectively and without causing any inconvenience such as deletion of images. For this purpose, when outputting the 1Ilii-like signal from the document reader 2 or the microfilm file 5, data indicating the size of the image is output, and the CPU 32 calculates the optimal pressure 1Ntei according to this data. The extraction timing selection circuit 44 is operated at the compression ratio.

Figure 7 shows the manuscript reader 2 and microfilm file 5.
This shows the format of the image signal output from. 111! A 4-bit size bit MD indicating the size of the image is provided before the image signal ID of the ii side.

This size bit MD automatically or manually recognizes the size of the original or microfilm frame in the original reader 2 and the microfilm file 5, and this F! A bit corresponding to the size of ga L is set. When inputting an image signal, the CPU 32 reads this size bit MD and controls the click generation timing of the extraction timing selection circuit 44 in order to perform a compression operation according to this size bit MD. Incidentally, FIG. 8 shows the image size indicated by the size bit MD in this system and the corresponding compression ratios 1 to R8. This compression rate is determined according to the resolution of the document reader 2 and microfilm file 5 and the resolution of the CRT 8, and is 140
Written to M33.

In this way, in parallel with the operation of storing the image signal input from the switching device Wi9 in the RAM 34 as it is, the CRT
Since compression processing for display is performed, input image signals can be quickly monitored. Further, the bit extraction circuit 38 described above can also be used for compression processing of an image signal read from the image @y isle 4.

When displaying the image signal read and output by the document reader 2 and the microfilm file 5 on the CRT 8, as described above, by performing thinning processing on the high resolution image signal and compressing the image signal, the IIE image is CR the entire area
It was designed to fit on the T. By the way, the soft display 6 connected to this system is capable of displaying images at a higher resolution than that of a CRT.

That is, the soft display 6 of this system has an A3 size display surface and can display images at a resolution of 16 pet/w. Further, as described above, the document reader 2 and the microfilm file 5 read and output the 1iiIf image at a resolution of 16 pet /am. Therefore, to monitor the read signal, use the soft display 6 that reproduces more detailed images than the CBr4, and send the output image signal from the document reader 2 and microfilm file 5 to the soft display 6 to display the same density as the read signal. This makes it possible to reproduce images of

By the way, the image size of the tiAg signal from the D;E, m reader 2 and microfilm file may be smaller than the 3 size. In such a case, a blank area will appear on the display screen of the soft display 6. Therefore,
Production information smaller than the displayable size of the soft display 6 is enlarged and displayed on the soft display 6 to effectively utilize the display image surface.

FIG. 9 shows a circuit configuration for achieving enlargement processing of an image (number g). This circuit is provided in the document reader 2 and the microfilm file 5.
This is a one-dimensional line sensor that reads an image line by line using an image sensor consisting of D. 81 is a drive circuit that drives the line sensor 80, and a signal read by the line sensor 80 is output onto the line 82 in synchronization with the clock CLI.

The clock CL2 corresponds to a line count, and specifically is a readout signal of the line sensor 80, and is a signal for transferring the charge accumulated in the photodiode of the line sensor to the shift register of the drive circuit 81.

CT1 and CT2 are 2-bit counters, and counter CTI counts clock CLI, and counter CT2 counts clock CL2, respectively. C1 and C2 are respectively counters CT1. This is a detector that detects the carry of CT2. SW is a switching signal that instructs whether or not to operate this enlargement processing circuit according to the image size of the image signal. Also, A
1-A4 is an AND gate, If, I2 is an inverter, 0
1,02 is or game), G3, G4 is gate, BF
is a 1-bit buffer, and LB is a line buffer.

Explain the operation. When the switching signal SW is at a low level, that is, when no enlargement processing is required, the AND gate A3
and A4 outputs p-level, therefore, Antogame)A
A high level Id@ is applied to I through the inverter 11 and the inverter I2, and to the analog voltage A2 through the inverter 2. This allows the clock CLI
and CL2 are input to the drive circuit 81 via AND gates Al and A2, respectively. Also, since gates G3 and G4 are also inactive, the clock CLI.

In synchronization with CL2, a serial image signal is output line by line to the output terminal OUT.

On the other hand, when the switching signal SW is at a high level, that is, when performing image signal enlargement processing, the
)A3. A4 becomes a high level output when each of the detectors CI and C2 outputs a carry detection signal. At this time,
Since the outputs of inverter 11 and I2 are at p-level, AND gates Al and A2 are connected to clocks CLI and CL2.
is no longer transmitted to the drive circuit 81.

Therefore, when the detector CI outputs the carry detection ID number, the drive circuit 81 receives the clock CLI? There is no manual input, and the drive circuit 81 does not output the image onto the line Bl. However, when the gate G3 is opened, the immediately preceding data (image signal) stored in the 1-pitch F buffer BP is outputted through the OR gate 01. That is, 4
The same M image signal is outputted once every four times, and the image signal in the line direction is expanded by 1.25 times.

Further, when the detector C2 outputs a carry detection signal, both the output signals CLI and CL2 are no longer input to the drive circuit 81. At this time, no image signal is output from the drive circuit 81, but the gate G4 is opened and the previous line image (No. 4) stored in the line buffer LB is output via the OR gate 02. That is, 1 in 4 lines
If there is no overlapping image output at the line rate, the image will be enlarged by 1.25 times in the direction perpendicular to the line direction (1ail scanning direction).

The aforementioned switching signal SW is output from the document reader 2, the microfilm file 5, or the control unit 1, and for example, automatically detects the size of the document MU transferred to the document reader 2,
When the document size is smaller than the display surface of the soft display 6 (for example, A4 size) or when an enlargement command is input by the operator, the switching signal SW is set to a high level to execute enlargement processing.

In this way, since the vi magnification signal is enlarged and displayed on the soft display 6, the display surface of the soft display 6 can be used effectively, and the enlarged display facilitates image recognition for the operator. It is something to do. Further, in this system, only 1.25 times enlargement is considered, but multiple enlargement ratios may be set to perform optimal enlarged display depending on the document size, etc. Further, the expansion in the sub-scanning direction may be performed by physically changing the sub-scanning speed of the line sensor.

By the way, the image signal continued by the document reader 2 is transmitted to the control unit 1.
When transmitting the data to a computer and storing it in the image file 4 having an optical disk, the operator inputs an operation command for the scanner from the keyboard 31 of the control unit 1. However, when operating the keyboard of the control unit l after setting a document on the document reader 2, there are the following drawbacks. That is, when the document reader 2 does not have an automatic document feeding device, or when handling images of book documents such as bound or fin documents, the operator must operate the document reader 2 and the control unit 1 each time. No.

In addition, when storing the image a signal read in the microfilm file 5 in the image file 4, the microfilm file 5 of this system has a microfilm frame search function, and the search command is issued by the control unit 1. Since this can be done using the keyboard, there is no need to operate two devices together, as described above.

Therefore, when storing the image signal continued by the document reader 2 in the image file 4, the operation command can also be input from the document reader 2. In FIG. 1, yi, document reader 2
There is an operation panel 21 for inputting operation commands for performing the functions of the digital copying machine, and this operation panel 21 is provided with a copy key 25. Therefore, in addition to the control unit 1, the copy key 25 can also be used to instruct the scanner to start for storing the image read by the document reader 2 (No. This is done using the changeover switch 22.

FIG. 10 shows the circuit arrangement for achieving this switching operation. 22a and 22b are two switches operated together by the mode changeover switch 22. switch 22a
When is on the contact A side, the scanner start signal @SS from the control section 1 is applied to the AND gate 83 from the contact A. At this time, if the original bias reader 2 is in an operable state and the scanner ready signal 98B is input to the AND gate 83, a scanner start command SC is output to the control section (not shown) of the document reader 2. On the other hand, switch 22
When b is on the contact port side, the scanner start signal SS from the control section 1 is not input to the AND gate 83.

If the copy key 25 of the document reader 2 is pressed at this time, a high level signal is input to the AND gate 83 in synchronization with the depression. In this case, if the scanner ready signal SR mentioned above is input to the AND gate 83,
A scanner start command SC is output.

Therefore, when the switch 22a is on the contact port side, by pressing the copy key 25, the scanner start command SC can be output in the same way as the scanner start signal SS from the control unit l, and this allows the document reading (scanning) to be performed. ) can be started.

The contacts of the switch 22b are switched together with the switch 22a, and the LEDs 23 or 24 respectively connected to the contacts are lit. This displays the current mode to the operator. Therefore, the operator can check the lighting status of LgD23, 24 and check whether the document is loaded or not. It is possible to perform procedures for inputting vI commands and perform cutting operations as necessary.

FIG. 11 shows a configuration of the circuit shown in FIG. @10 using a logic circuit. In this circuit, mode switching is performed from the control section 1. When starting the document reader 2 from the control unit 1, an instruction to that effect is given from the keyboard 31, and the remote signal S is inputted to the set terminal of the knob 87, and this flip full tube 8
Set 7. In this manner, when the 7-rip 7-4 87 is set, the next high-frequency signal is output from its Q terminal to the AND gate 84.

At this time, the control unit 1 starts the scanner No. 13 SS.
If the above-mentioned scanner ready signal SImo is input to the AND gate 84, the scanner start command SC is input to the control section of the document reader 2 via the OR gate 86, and scanning of the document is started.

On the other hand, when the scan Di (start command) of the document reader 2 is performed using the copy key 21 of the document reader 2, when an instruction to that effect is given from the keyboard 31, the remote signal S becomes low level, and the four-cal The signal LS becomes high level.This resets the 7-lip flop 87, the Q output to the AND gate 84 becomes low level, and the Q output to the AND gate 85 becomes high level.

At this time, when the copy key 25 is pressed down, a high level input is made to the AND gate 85. In this case, if the scanner ready signal SR is input, the scanner start command SC is sent from the AND gate 85 via the OR gate 8G. Output. At this time, the scanner start signal SS from the scanner 1 section 1 is not transmitted to the OR gate 86 because the AND gate 84 is closed.

Further, like the circuit shown in FIG. 10, the LEDs 23 and 24 are turned on according to the mode to display the current mode to the operator.

FIG. 12 shows yet another embodiment, in which the scan start command for the document reader 2 can be switched in three ways, such as from either the document reader 2, the control section 1, or both. That is, the switches 22c, 22d, and 22e, which are operated together by the mode changeover switch 22, are 3@way, 3-contact switches. And switch 22c.

22d is connected to the contact port, both the scanner star from the control unit (SS No. 1 and the signal caused by pressing the copy key 25) can be input to the AND gate 90 via the OR gate 91. When the mode is selected, both the control unit 1 and the document reader 2 can issue a command to start the document reader.

Further, when the switches 22c and 22d are connected to the contacts A, the original reader 2 can be activated only from the control unit 1, and when the switches 22c and 22d are connected to the contacts C, the original reader 2 can be activated only from the original reader 2.

In this way, since the activation of the document reader 2 can be switched from the control unit 1 or from the document reader 2 as necessary, it is also possible to issue a startup command at the same position as the document is set in the document reader 2. The system is easy to use.

FIGS. 13(a) to 13(C) are flowcharts showing the control procedure of the system described above. The program shown in this 70-chart is written in the ROM 33 of the control unit 1 in advance, and the CPU 32 writes this program to the ROM.
The read control operation starts from 33.

When the power is turned on to the control unit 1 of this system, first, in step S1, the screen of the CRT 8 is cleared, and then,
In step S2, a display waiting for command input is displayed on the CRT 8 in preparation for operation of the keyboard 31 by the operator. Typical commands input by the operator are:
An image input command for loading the image signal into the AM 34 of the control unit 1, an image output command for reading and outputting the image signal from the RAM 34 of the control unit 1, and a path for transmitting and receiving the image signal without going through the control unit 1. There is a mode command.

The control unit 1 first checks in step S3 whether an image input command has been input by the operator. If no input has been made, the process advances to step 815 to see if an image elevation output command has been input.

If an image input command has been input, step 84.87

After the above-described image input is completed, or if no image input command has been input from the operator, it is determined in step 815 whether or not an image output command has been input.

If an image output command has been input, step 816;
il! by 818, 820, 822 and 824! ! Determine what is specified as the output device. If CRT8 is designated as the image output command, the process advances from step 816 to 817, where a drive command is output to CR'I'8, and the process advances to step 826. If the image file 4 has been designated, a drive command is output to the H image file 4, and the process proceeds to step 826 after ensuring that the image file 4 has a storage area for the M image signal. If the high-speed printer 3 is designated, the process proceeds from step 820 to 821, and a drive command is issued to the high-speed printer 3, causing the high-speed printer 3 to start preparatory operations such as laser output, mirror rotation, and feeding, and at the same time, the switching device 9 is switched on. Turn on the switch 61 and turn on the high-speed printer 3.
After forming the signal path to, proceed to step 826. If the soft display 6 has been specified, the process advances from step 822 to step 823, where the soft display 6 is activated and Ii! After making preparations for Ii transmission display and turning on the switch 62 of the switching device to form a signal path, the process proceeds to step 826. On the other hand, if the small printer 7 is specified, a drive command is output to the small printer 7, and the switch 63 of the switching device is turned on to form a signal path to the small printer 7, and then the process advances to step 826.

In step 826, the R
The III image signal stored in the AM 34 is output, and the image recording or DM image display operation is executed.

In step 827, it is determined whether a bus mode for transmitting and receiving image signals without going through the control unit 1 has been designated by the operator. If a pass mode has been specified, the combination of input and output devices used for that pass mode is determined in steps 828, 830, 832, 834, 836 and 838.
The judgment is 11i. I! i, Kai reader 2 and high speed printer 3
If the combination of is specified, steps 828 to 829
