Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus for subjecting image data to processing and outputting the processed data simultaneously to a plurality of positions on a screen.

[0002]

2. Description of the Related Art For example, the technology related to this type is as follows.
There is a copying machine disclosed in Japanese Utility Model Laid-Open No. 63-44565. In such a technique, an image read from a scanner is stored in an image memory, and an output designating unit designates a range to be repeated, the number of repetitions, a repeating address, etc.,
According to the designation, the image data to be repeated is read from the image memory, and a plurality of “repeated images” are output (repeated) on the recording paper. In this copying machine, the output "repeated image" is fixed (1
The images are repeatedly output without gaps in one output screen, or are output diagonally).

[0003]

However, in the above-mentioned conventional technique, images are repeatedly output according to a predetermined pattern (or selected by the input data). Therefore, on the output image, the pattern of repeated image generation is limited to a fixed pattern, and there is no degree of freedom.

Therefore, an object of the present invention is to provide an image processing apparatus capable of obtaining a repetitive image in which the repetitive image generation frequency and generation position are random.

[0005]

In order to achieve the above object, the present invention provides an image storage unit for storing image data obtained by reading a document or the like, and data for reading the image data from the image storage unit. A reading unit, a trigger generating unit that randomly sends a trigger signal to the data reading unit, an image storage unit that stores one page of image data read from the image storage unit, and an image storage unit that stores the image data from the image storage unit. An image output unit for outputting image data to a recording medium is provided.

Further, the above-described object is to provide an image storage unit for storing image data obtained by reading an original, a data reading unit for reading image data from the image storage unit, and a trigger signal for the data reading unit at random. And a trigger position control unit that controls the generation position of the trigger signal generated by the trigger generation unit, and an image output unit that outputs the image data from the image storage unit to a recording medium. It can also be achieved by a configuration.

In order to be able to set the maximum number of repetitive images from the outside, it is possible to provide a trigger frequency control means for controlling the frequency of generation of the trigger signal generated by the trigger signal control section.

[0008]

According to the above-mentioned means, the data reading section is
The trigger signal is output at random so that a "repeated image" can be generated at a random position on the output image. Therefore, the read image can be repeatedly output at random positions on the recording medium, and a new visual effect can be produced.

Further, since the trigger position control section is provided, the generation position of the trigger signal randomly output by the trigger signal generation section can be controlled. Therefore, it is possible to prevent the phenomenon that the "repetitive image" is interrupted near the end portion of the output image, and it is possible to provide a fine repeat process.

Further, by providing the trigger frequency control means, it is possible to set a parameter for determining a condition for trigger signal generation in the trigger signal generator from the outside.
The frequency of trigger signal generation is controlled. As a result, the spatial density of the repeated image in the output image can be controlled, and the repeated image density can be made different depending on the line position on the output screen, so that various “repeated images” can be obtained.

1 is a block diagram showing an embodiment of an image processing apparatus according to the present invention. The image processing devices shown individually are
An image reading unit 1 that reads image data on a document, an image storage unit 2 that stores the image data read by the image reading unit 1, and a data reading unit 3 that sends a data reading signal to the image storage unit 2 to read the image data. A trigger generating section 4 for sending a random trigger signal to the data reading section 3 to operate the data reading section 3 at random, an image storage section 5 for storing one page of the image signal read from the image storage section 2,
Each of the image output units 6 (for example, printers) outputs the image signals stored in the image storage unit 5 to a predetermined recording medium.

Next, the operation of the embodiment having the above configuration will be described. The image reading unit 1 reads the image of which the area is specified on the document and stores it in the image storage unit 2. When the image data is read from the image storage unit 2, the trigger signal is sent from the trigger generation unit 4 to the data reading unit 3, and the data reading unit 3 is activated. By sending a data read signal from the data reading section 3 to the image storage section 2, designated data is read from the image storage section 2. The read image data is transferred to the image storage unit 5, then sent to the image output unit 6 for image output (printing), and the read image is repeatedly output at random positions on the recording medium.

FIG. 2 is a block diagram showing a configuration example in which the present invention is applied to a printer.

The apparatus shown here is a scanner section 7 corresponding to the image reading section 1 in FIG. 1, a memory section 8 corresponding to the image storage section 2, a trigger signal generating section 9 corresponding to the trigger generating section 4,
An address signal generating section 10 for generating an address signal based on the trigger signal from the trigger signal generating section 9, a page memory section 11 corresponding to the image storage section 5, a printer section 12 corresponding to the image output section 6, and a trigger signal generation. The control signal generating unit 13 sends control signals (clock signal, line synchronization signal, etc.) to each of the units 9 to 12.

In the above configuration, assuming that the image data is a mono-color binary image, description will be made with reference to FIGS. 3 and 4. The image data 14 as shown in FIG. 3 stored in the memory section 8 is read from the memory section 8 by the address signal generating section 10 and stored in the page memory section 11 as an image 15 shown in FIG.

FIG. 4 is a timing chart showing the read timing of image data. Data reading starts from the beginning of one line of the memory unit 8 from the time when the trigger signal is input, and at this time, the position (xoffset) at which the trigger signal is received based on the line synchronization signal is set in the latch of the page memory unit 11. Remember. Predetermined amount (xsiz
e: The generation of the address signal is stopped when the data in the vertical direction) is read. In the second and subsequent lines, the generation of the address signal is started by the line synchronization signal and the xoffset value, and the generation of the signal is stopped after reading the data for xsize. Similarly, ysize (horizontal direction)
Minute data is read. When the data reading for one page is completed, the printing by the printer unit 12 is performed based on this.

Thus, for example, in the prior art,
As shown in (a) of FIG. 5, the image read in the same pattern on the output image is output, but according to the present invention, the output image as shown in (b) is obtained, and a new visual effect is obtained. Repeated images can be obtained. Further, even when a trigger signal is generated during data reading, the data can be temporarily stored in the image storage unit and sequentially overwritten to obtain a repetitive image with a high occurrence frequency as shown in (c).

When a new trigger signal is input to the address signal generating section before all the image data stored in the memory section 8 is read out, the following processing is performed.

For example, as shown in the timing chart of FIG. 6, when two trigger signals are generated in one line, the first trigger causes the page memory unit 11 to start writing the contents of the memory unit 8. In the second trigger generated during the writing, the memory unit 8 is not accessed, and the line position and xoffset at that time are latched in the address signal generation unit 10. When the writing to the page memory unit 11 by the first trigger is completed, the memory access by the second trigger is started, and the image signal is overwritten at the xoffset position of the page memory unit 11. Thereafter, in the same manner, the data of ysize and the data of each line are read. In addition, the trigger signal is sent to the address generator 1 during memory access on a line other than the same line.
The same process is performed when 0 is input.

FIG. 7 is a block diagram showing a second embodiment of the present invention. In this embodiment, the same reference numerals are used for the same components as those in the above-mentioned embodiment, and the duplicated description will be omitted here. As shown in FIG. 7, the present embodiment is characterized in that the image storage unit 5 is omitted and the image storage unit 2 is directly read out to the image output unit 6. Then, when the image signal is read from the image storage unit 2 to the image output unit 6, the image data is sent to the image output unit 6 at random timing by a control unit (not shown), and the image data is sent to a random position on the recording medium. The read image is repeatedly output.

A concrete configuration example is as shown in FIG. 8, in which a trigger position control section 16 is connected to the trigger signal generation section 9, and FIG.
This embodiment is characterized in that the page memory unit 11 is removed and the printer unit 12 is brought to the position of the page memory unit 11.

In this configuration, the image data 14 shown in FIG. 3 stored in the memory section 8 is read by the address signal generating section 10 and output to the printer section 12. At this time, the address signal generation unit 10 starts reading data from the beginning of one line of the memory unit 8 from the time when the trigger signal is input, and at this time, the position (xoffset) at which the trigger signal is received based on the line synchronization signal. ) Is stored in the latch. Hereinafter, xsiz is performed as described with reference to FIG.
The data for e and the data for ysize are read and the printer output is obtained.

In this embodiment, an enable signal for controlling the trigger signal output is output from the trigger position controller 16 to the trigger signal generator 9, and the trigger signal triggers only when the enable signal is active. It is output from the signal generator 9. For example, the enable signal as shown in FIG. 9 is generated, and the generation of the trigger signal is prohibited in the section 17. By such an operation, an image which is interrupted at the right end of the output as shown in FIG. 10 is not generated in the output image.

The address signal generator 10 prohibits / permits the interrupt of the trigger signal at the time of generating and ending the address signal in one line, and does not accept the interrupt request of the trigger signal during the signal output. To do.

According to the configuration of FIG. 8, assuming that the repetitive image of the conventional method is as shown in FIG.
As shown in (b) of (1), it is possible to obtain a repeated image that produces a visual effect.

Further, in FIG. 8, the trigger position control unit 1
It is also possible to set a parameter in 6 to determine the conditions for trigger signal generation in the trigger signal generation section so that the frequency of trigger signal generation can be controlled. By doing so, the spatial density of the repeated image in the output image can be controlled. For example, it is possible to perform control such that the upper limit of the trigger signal generation frequency per page is designated from the outside, or the address being currently scanned is fed back to the trigger signal control unit as the upper limit of the generation frequency. In this case, the address signal generation unit 10 prohibits / permits the interrupt of the trigger signal at the time of generating and ending the address signal in one line, and does not accept the interrupt request of the trigger signal during signal output. ..

For example, if the repetitive image shown in FIG. 12 is used in the conventional method, the output image shown in FIG. 13 can be obtained by controlling the frequency of trigger signal generation. As a result, it is possible to obtain a repeated image that produces a new visual effect.

Specifically, by setting the maximum number of repeated images generated in one screen from the outside by the trigger frequency control means, the user can specify the repeated image density. Further, by feeding back the write address to the trigger frequency control means, as shown in FIG. 14, it is possible to obtain a variety of repetitive images such that the repetitive image density can be varied depending on the line position of the output screen.

The present invention is not limited to the mono-color binary system, and can be applied to full-color multi-value system. By adding a common address signal generator and trigger signal generator to each memory of Y, M, G (or R, G, B), it is possible to obtain a full-color repetitive image.

In the above embodiment, an example in which an image is output on a recording sheet by a printer has been shown, but it can be used for storing image data in a magnetic recording medium by a computer or the like.
