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 processing data input from an external device such as a host computer.
Connected to an image printing device for printing processed image data.
An image processing apparatus or the like to be continued.

[0002]

2. Description of the Related Art Conventionally, in an image processing system or the like in which image data or the like created by an external device such as a host computer is processed by an image processing device and printed by an image printing device, the image processed by the image processing device is processed. The configuration is such that data is transferred to the image printing apparatus every page.

When image data input from an external device to an image processing apparatus is, for example, a page description language (PDL), the data is developed as a raster image in the image processing apparatus, and thereafter, is output to a printing apparatus. Had been output.

[0004]

The above-described conventional image processing system is configured to perform image processing for each page of image data and transfer the image data to an image printing apparatus. For example, when printing a plurality of copies, the feeding of the recording paper for the next page is started before the printing of the image data for one page is completed. When printing is performed sequentially one by one, after the printing of the image data for one page is completed, the feeding of the recording paper for the next page is started. Therefore, when the input image data is sequentially printed one by one, the printing time per recording sheet becomes longer. Further, since the cleaning operation is performed every time printing of one page of image data is completed, the time required for printing is further increased, and the waste of power consumption is large.

Further, while image data is being transferred from the outside to the image printing apparatus, no processing is executed in the image printing section (eg, printer engine) of the image printing apparatus. There is a disadvantage that all consumed power is wasted.

[0006] The purpose of the present invention is to provide it is possible to shorten the printing time of the connected image printing apparatus, an image processing apparatus or the like which can save power consumption.

The type of image processing performed by the CPU 103 can be changed by changing software. The CPU 103 also controls circuits of each unit of the apparatus, issues control commands to the image printing apparatus 112, and the like.

The ROM 104 stores an execution program for image processing performed by the CPU 103 and control of circuits of each unit of the apparatus. By changing the content of the execution program, the operation content of the image processing apparatus 100 can be changed. The work RAM 105 stores temporary image data when the CPU 103 performs image processing,
Stores data required for program execution.

The hard disk 106 stores the image data subjected to the image processing by the CPU 103 in the image printing apparatus 11.
2 until it is transferred. The controller 107 includes a memory in which image data is stored and the hard disk 10.
6 for managing the transfer of data to and from
This enables high-speed DMA (direct memory access) transfer of image data in place of the CPU 103.

The second I / O interface 108 is for sending image data stored in the hard disk 106 or the memory to the image printing apparatus 112, and is for sending control signals to the image printing apparatus 112 and The information about the state of the printing apparatus 112 is obtained. The internal bus 109 includes a data bus, an address bus, a control signal line, and the like, and transmits various information.

The memory controller 111 manages writing and reading of image data in the frame memory 110, and also refreshes data in the frame memory 110.

Next, referring to FIG.
Will be described. FIG. 2 is a block diagram illustrating a schematic configuration of the image printing apparatus 112.

The image processing device 112 includes an I / O interface 501, a CPU 502, an image printing unit 503, a display unit 504, and the like.

The I / O interface 501 mediates input of image data and various control commands from the image processing apparatus 100. The CPU 502 controls the operation of the image printing device 112. The image printing unit 503 prints image data on recording paper. The display unit 504 displays various control data and the like.

Next, FIG. 3 to FIG. 7 together with FIG. 1 and FIG.
The operation of this embodiment will be described with reference to FIG. FIG. 3 is a flowchart illustrating processing performed by the CPU 103 of the image processing apparatus 100.

First, image data is transferred from the host computer 101 to the image processing apparatus 100, and the transferred image data is transmitted to the first I / O interface 102,
Frame memory 11 via memory controller 111
It is stored in 0 (step S1).

FIG. 4 is a diagram showing the power consumption of the image printing apparatus 112 for each mode. In the figure, a “print mode” is a mode when image data is actually printed in the image printing unit 503, and consumes the most power because each unit of the apparatus is operating.

In the “standby mode”, the image processing apparatus 1
The print mode is shifted to the print mode as soon as the print command is notified from 00. In the standby mode, the power supply to the display unit 504 is stopped, and the temperature of the toner fixing unit (not shown) is set to By lowering the power, the power consumption in the image printing unit 503 is lower than that in the print mode.

The “shut-off mode” is a mode in which the power supply to other parts is stopped while leaving only the interface part for communicating with the image processing apparatus 100. In the shut-off mode, the power consumption is the minimum, but even when a print command is notified from the image processing apparatus 100, it is necessary to perform a reset operation of each unit or to raise the temperature of the toner fixing unit to an appropriate temperature. It takes time to shift to the print mode.

In this embodiment, the image printing apparatus 112 is in a standby state until the printing operation is actually started, so that the power consumption can be reduced.

Referring back to FIG. 3, in step S1,
When the storage of the image data transferred from the host computer 101 to the image processing apparatus 100 in the frame memory 110 is completed, the CPU 103 reads out the image data from the frame memory 110 according to the program stored in the ROM 104 and performs image processing (step S2).

When executing the image processing, the CPU 103
Temporary image data is stored in the work RAM 105 as needed, and when the image processing is completed,
Stores the processed image data. If it is not necessary to store the processed image data in the frame memory 110, the hard disk 106 or the image printing device 11
2 can also output image data.

If the capacity of image data from the host computer 101 is too large to be stored in the frame memory 110, the first I / O interface 102
It is also possible to store the image data directly in the hard disk 106 via the controller 107.

Next, it is determined whether or not it is necessary to immediately print the image data sent from the host computer 101 and subjected to image processing (step S3). Is spooled on the hard disk 106 via the memory controller 111 and the controller 107 (step S4).

FIG. 5 is a selection screen displayed on the display unit or the like of the host computer for the user to select whether or not to spool the image data in step S4. In the figure, reference numeral 401 denotes an image to be selected, reference numeral 402 denotes a display area of a file name for storing image data, and reference numeral 403 denotes a selection button for selecting whether or not to spool the image data.

The user selects "NO" of the selection button 403 if he wants to print immediately, and selects "YES" if he spools the image data once. This selection information is transferred to the image processing apparatus 100 together with the image data. The CPU 103 changes the processing method of the image data based on the transferred selection information. When spooling image data, the operation of image processing the image data received from the host computer 101 and spooling the image data to the hard disk 106 is repeated until a predetermined amount of image data is spooled to the hard disk 106.

Returning to FIG. 3, it is determined whether or not the image data spooled on the hard disk 106 has reached a predetermined amount (step S5).
Return to 1. If it has reached, the activation process of the image printing unit 503 is performed (step S6).

That is, the CPU 103 of the image processing apparatus 100
The instruction to shift to the “print mode” is sent from the CPU 5 of the image printing apparatus 112 via the I / O interface 501.
02 is notified. Upon receiving the notification, the CPU 502 increases power supply to the toner fixing unit of the image printing unit 503 to increase the temperature, and displays the display unit 504.
The processing for shifting to the print mode, such as the start of power supply to the printer, is performed.

When the image printing unit 503 completes the transition to the print mode and is notified to the image processing apparatus 100, the image processing apparatus 100 outputs the image data spooled on the hard disk 106 to the image printing apparatus 112 (step S).
7).

FIGS. 6 and 7 show consumption in the image printing unit 503 when image data is sent to the image printing apparatus 112 for each page of a sheet and when a predetermined amount of spooled image data is sent together. It is a graph for comparing and explaining transition of electric energy. FIG. 6 shows the image processing apparatus 100.
FIG. 7 is a diagram showing changes in power consumption when image data for one page is transferred from the image processing apparatus 112 to the image printing apparatus 112 for printing. FIG. FIG. 7 is a diagram illustrating a change in power consumption when image data is transferred collectively and printed.

As shown in FIGS. 6 and 7, it is necessary to perform pre-processing such as potential adjustment in the image printing apparatus before actually printing the image data. It is necessary to perform post-processing such as The time for executing the pre-processing and the post-processing is, as shown in both figures,
Since the image data does not change depending on the number of recording sheets to be printed, as shown in FIG. Processing and post-processing may be performed.
Power consumption for printing per page can be reduced.

Returning to FIG. 3, when the printing of the image data output from the image processing apparatus 100 to the image printing apparatus 112 is completed in step S7 and the image processing apparatus 100 is notified, the standby state of the image printing unit 503 is set. A transition process to the mode is performed (step S8). That is, the image processing apparatus 100 issues an instruction to the image printing apparatus 112 to shift to the standby mode. I / O interface 5
When the instruction to shift to the standby mode is sent to the CPU 502 via the CPU 01, the CPU 502 stops the power supply to the display unit 504, controls the temperature of the toner fixing unit to be low, and ends the processing. .

In step S3, if it is not necessary to immediately print the image data sent from the host computer 101 and subjected to the image processing, an instruction to shift to the print mode is issued to the image printing apparatus 112 immediately. The image printing apparatus 112 is shifted to the print mode (step S
9) The image data that has been subjected to image processing and stored in the frame memory 110 is output to the image printing device 112 (step S10), and the process proceeds to step S8.

Next, a second embodiment of the present invention will be described with reference to FIGS. Note that the basic configuration of the image processing system of the present embodiment is the same as that of the first embodiment, and thus, in the following description, the above-mentioned reference numerals are used.

FIG. 8 shows the C of the image processing apparatus 100 of the present embodiment.
4 is a flowchart illustrating a process performed by a PU 103. FIG. 9 is a graph for explaining a change in power consumption when printing is performed by the image printing apparatus 112 according to the present embodiment.

In FIG. 8, the host computer 101
Is transferred to the image processing apparatus 100 from the hard disk 1 (step S11).
06, and confirms whether or not a predetermined amount of image data has been reached (step S1).
2). If the predetermined amount of image data has been reached, the image printing unit 503 of the image printing apparatus 112 is activated, and
If the predetermined amount of image data has not been reached, the image printing unit 503 takes no action and proceeds to the next process.

At this time, the image printing apparatus 112 is in the “shut-off mode”, and power is not supplied to any parts other than the I / O interface 501 for communicating with the image processing apparatus 100. As a result, the power consumption of the image printing unit 503 other than when printing image data can be significantly reduced.

In step S11, the image data transferred from the host computer 101 is stored in the hard disk 106 after image processing. When the image data stored in the hard disk 106 reaches a predetermined amount, C
The PU 103 issues an instruction to shift to the standby mode to the image printing apparatus 112 (Step S13). I /
When the instruction to shift to the standby mode is notified to the CPU 502 via the O interface 501, the CPU 502
Performs control so as to energize each part of the device operating in the standby mode.

On the other hand, in the image processing device 112, image data newly sent from the host computer 101 is stored in the frame memory 110. Frame memory 1
10 is subjected to image processing (step S1).
4) After the end, it is stored in the frame memory 110 again (step S15).

When the reception of all the image data is completed, the image processing apparatus 100 issues a command to the image printing apparatus 112 to shift to the print mode. I / O interface 5
When the instruction to shift to the print mode is sent to the CPU 502 via the “01”, the CPU 502 energizes the display unit 504 and raises the temperature of the toner fixing unit of the image printing unit 503 to the temperature in the print mode. (Steps S16 and S17).

The image printing apparatus 100 to the image processing apparatus 11
2 is notified that the transition to the print mode is completed, the image processing apparatus 112 outputs all the image data stored in the hard disk 106 to the image printing apparatus 112 (step S18). When all the image data in the hard disk 106 is output to the image printing device 112, the new image data stored in the frame memory 110 is transferred to the image printing device 112 (step S).
19). When the image processing apparatus 100 is notified that the transfer of all image data in the image processing apparatus 100 has been completed and the image printing apparatus 112 has finished printing all image data, the image processing apparatus 100 starts image printing. Device 112
(Step S20).

After the transition to the standby mode has been completed, new image data is stored in the image processing apparatus 1 even after a prescribed time has elapsed.
If the input is not input to 00, the image processing apparatus 100 issues a shut-off command to the image printing apparatus 112 to shut off the image printing apparatus (steps S21 and S22),
The process ends.

As described above, according to the image processing system of the present embodiment, the power supply to the image printing apparatus 112 is shut off while the printing of the image data is not executed, so that the image printing apparatus 112 consumes power. Required power can be significantly reduced.

Next, a third embodiment of the present invention will be described with reference to FIGS. Since the basic configuration of the image processing system of the present embodiment is the same as that of the first and second embodiments, the same reference numerals are used in the following description.

FIG. 10 is a flowchart showing the flow of processing performed by the CPU 103 of the image processing apparatus 100 according to this embodiment. FIG. 11 is a graph illustrating a change in power consumption when printing is performed by the image printing apparatus 112 according to the present embodiment.

In this embodiment, the host computer 101
Until image data is transmitted to the image processing apparatus 100.
The image printing apparatus 112 is in the shut-off mode, and does not uselessly supply power to the image printing unit 503 to reduce power consumption. In this embodiment, the image data sent from the host computer 101 to the image processing apparatus 100 is described in PDL (Page Description Language).

When transfer of image data from the host computer 101 to the image processing apparatus 100 is started, the CPU
103 issues a command to shift to the standby mode to the image printing apparatus 112 (step S31). Also, C
The PU 103 develops the PDL data transferred from the host computer 101 into a raster image on the frame memory 110 (Step S32). When the transfer of the PDL data from the host computer 101 is started and a specified time has elapsed, the CPU 103 issues a command to shift to the print mode to the image printing apparatus 112 (step S).
33, S34). The specified time may be a time until the transfer of the PDL data is completed or a time arbitrarily determined by the user.
01) is determined according to the image transfer processing speed and the image processing speed of the image processing apparatus 100.

When an instruction to shift to the print mode is sent to the CPU 502 of the image printing apparatus 112 via the I / O interface 501, the CPU 502
The temperature of the toner fixing unit 3 is increased, and the display unit 504 is energized to put the image printing apparatus 112 in a printable state. When the image processing apparatus 100 is notified that the image printing apparatus 112 is ready for printing, the frame memory 1
The image data developed from the PDL data into the raster image on the printer 10 is transferred to the image printing device 112 (step S35).

When the image printing apparatus 112 notifies the image processing apparatus 100 that printing of the transferred image data has been completed, the image processing apparatus 100
To the standby mode. CPU5
02 receives a command to shift to the standby mode, and stops the power supply to the display unit 504 and performs control to lower the temperature of the toner fixing unit of the image printing unit 503. When the transition to the standby mode has been completed and new image data has not been input to the image processing apparatus 100 even after the specified time has elapsed, the image processing apparatus 100 issues an instruction to the image printing apparatus 112 to transition to the shut-off mode. And the image printing device 11
2 is shut off (steps S36 and S37).

As described above, according to the image processing system of this embodiment, while the PDL data sent from the host computer 101 is developed into a raster image, the image printing No power is supplied, and immediately after rasterization of the PDL data into raster images is completed, the raster image data in the frame memory 110 is immediately output to the image printing device 112, so that unnecessary power consumption can be suppressed. .

The image processing apparatus described in each of the above embodiments may be mounted inside an image printing apparatus.
It may be provided independently of the image printing device. Further, the present invention can be applied to input / output of image data from an arbitrary external device.
