Abstract

PURPOSE:To attain synthesis and edit of picture freely by outputting a picture signal of a picture generator synchronously with a control signal of a picture reader according to the operating mode set by an operation input display device or the above picture generator. CONSTITUTION:Since a picture signal synchronously with a control signal passing through a system controller 5 as it is outputted from a picture reader 1 to a picture forming device 4, copy is executed without interposing a memory with a large capacity on its way. Moreover, since the picture generator 2 outputs a picture signal synchronously with the control signal from the system controller 5, the picture forming device 4 handles the signal entirely equal to the signal from the picture reader 1 to attain print-out. Thus, two pictures are easily synthesized and edited.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an image editing device applied to a digital copying machine or a composite machine of a digital copying machine and an optical file system, and particularly relates to an image editing device for image signal formation. This invention relates to a distinctive image editing device.

[Conventional technology]

Digital copying machines electrically read and digitally process image signals, making it possible to perform various types of image editing.

For example, digital copying machines that have the function of adding simple information such as date, pagination, and stamp are well known.

Further, a filing system that has an image signal memory for one page and performs image editing on the memory is also known.

[Problem to be solved by the invention]

However, the digital copying machine described above cannot handle information sent from an external device, such as a computer.

On the other hand, devices that convert information from a computer into electrical image signals and print them out (laser beam printers,
Although there are electrostatic plotters (electrostatic plotters), there is no device that combines and outputs an image signal from an image reading device. This is because synchronization of mutual image signals becomes complicated.

In the above-described filing system, image signals are stored in the memory at once, so that composition and image editing can be performed freely. However, there are disadvantages in that the storage memory is expensive and the image editing equipment is also expensive.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an image editing device that eliminates the drawbacks of the prior art described above and allows image editing to be performed easily.

[Means to solve the problem]

In order to achieve this object, the present invention provides an image reading device that reads a document with a sensor, performs appropriate processing, and outputs an electrical image signal, and connects it to an external device, and uses information from the external device to output an electrical image signal. an image generating device that generates an image, an operation input/display device having an input means and a display means, an image forming device that prints out an electrical image signal on paper or the like, and the operation input/display device, or According to the operation mode set by the control signal of the image generator,

[Effect]

In the present invention, since the control signal from the image reading device is simultaneously supplied to the image generating device and the image forming device by the switch, the image signal of the image reading device and the image signal of the image generating device are synchronized and combined and printed out. .

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a system block diagram of an image editing apparatus according to an embodiment of the present invention, in which a document is read by a sensor,
An image reading device 1 that performs appropriate processing and outputs an electrical image signal, an image generating device 2 that is connected to an external device and generates an electrical image based on information from the external device, input means such as keys, and An operation input/display device 3 having a display means such as an LED, LCD, or CRT, an image forming device 4 that prints out electrical image signals on paper or the like, and an image reading device 1
1. Image generator 2. Operation input/display device 3. Consists of an image forming device 4, etc., and a system control device 5 that controls the entire device while transferring information via control signals.

In such a configuration, control signals (FGATE, LGATE) are transmitted from the image reading device 1 to the image forming device 4 by passing through the system control device 5 as they are.

Since image signals (data 1.2) synchronized by LSYNC, CLOCK, PMSYNC, and serial transmission are output, copying can be performed without intervening a large-capacity memory. Furthermore, since the image generating device 2 outputs the image signal in synchronization with the control signal from the system control device 5, the image forming device 4 can print out the signal by treating it exactly the same as the signal from the image reading device 1. .

Next, the synchronization method will be explained. System control device 5
The control signal output from the image generating device 2 to the image generating device 2 can be selected from an internal timing generator (T, G,) or a signal from the image reading device 1 by a switch in the system control device 5.

The image signal output from the image generating device 2 is classified into a normal output mode (when internal T, G, is used) and a synchronous output mode (when an image reading device signal is used) according to the above selection.

In the normal output mode, when the image generation device 2 finishes converting the information transferred from the external device into an image signal for one sheet of transfer paper, it transmits a preparation completion signal to the system control device W5 through the serial port.

Then, the system control device 5 transfers necessary information to the image generating device 2 and the image forming device 4, and print output is performed from the image generating device R2 to the image forming device 4. This is-
The operation is exactly the same as that of a boat-based printer or plotter.

A feature of the present invention is the synchronous output mode. The synchronization utility mode is set below with reference to the flowchart shown in FIG.

(2) Mode setting change: First, when the system control device 5 is in the normal output mode (No in 2-1), it changes the setting to the synchronous output mode. The mode switching request (2-2) is input by the operator from the operation input/display device 3, or a synchronous output mode request is sent from an external device and the request is made to the system control device 5 through the image generator 2. There are two ways.

■Mode setting complete; Next, the system waits after a switching request occurs until setting switching is actually possible.

This is because, for example, switching cannot be performed while the image forming apparatus 4 is performing print output. The system control device 5 switches the switch to complete the setting (YES in 2-4).

■Image reading device 11 waits for image generating device 2 to be ready; In normal output mode, it would be better to wait for image generating device 2 to be ready (YES in 2-3), but in synchronous output mode, image reading device 1 is ready. also have to wait. When the preparation for resetting the device is completed (YES in step 2-5), the system control device 5 displays the completion of preparation to the operator via the operation input display device 3.

■Waiting for the image reading device; Next, it actually starts reading the image (YES in 2-6), but in this case, if the image reading device 1 has a document feeder and there is a document, it will wait for the image to read immediately. , otherwise reading is started by the operator's key operation.

■Image output: When image reading starts, the control signal from the image reading device l is sent to the image generating device 2 by a switch.
Since the image signals are simultaneously supplied to the image forming device 4, the image signals of the image reading device 1 and the image signals of the image generating device 2 are synchronized and combined and printed out (2-7).

Furthermore, as shown in FIG. 3, by adding AND circuits 5a, 5b, and OR circuit 5c to the system control device 5 and controlling each control signal, it is possible to erase image signals at unnecessary locations. can. Similarly, an additional circuit inverts
It also becomes possible to perform simple signal processing such as a combination of erasure and inversion.

Also, the FG from the system control device 5 to the image generation device 2
The delay circuit 5d outputs the ATE output as shown in the configuration of FIG.
By delaying the setting, as shown in the timing chart of FIG. 5, the image signal from the image reading device 12 and the image generating device 2 is shifted through the OR circuit 5e and printed out.

FGATE is a signal that controls the leading and trailing edges of the image in the paper feeding direction. The image forming apparatus 4 makes the point in time when FGATE from the system control device 5 changes from low to high coincide with the leading edge of the transfer paper. Further, the image reading device 1 starts outputting the leading edge of the image in synchronization with the rising of its own FGATE, and the image generating device 2 starts outputting the leading edge of the image in synchronization with the rising of FGATE from the system control device 5. .

Therefore, as shown in FIG. 5, the print output is also shifted by the amount that FGATE is shifted. By doing this, the image on the transfer paper can be moved with a simple operation (see FIG. 6).

Further, the above operations can be selected in any combination based on information from the operation input/display device 3 or an external device, thereby expanding the image editing function.

〔Effect of the invention〕

As described above, according to the present invention, two images can be easily combined and image editing can be performed.
