[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing evaluation processing device, and more particularly to a development support tool for developing a program for an image processing processor and verifying an image processing result in a system for performing image processing such as a copying machine. is there.

[0002]

2. Description of the Related Art In the development of image processing for copying machines, etc., it depends on the verification of the image processing program based on the print result on the actual machine, and when an abnormality is found in the print result, it is difficult to analyze the cause. It takes labor. In particular, when performing multiple image processing, it is necessary to incorporate a mechanism for extracting intermediate data into the operating environment of the actual machine in order to check which image processing caused the abnormality, and anyone can easily do this. It is not possible to build an environment for evaluation and analysis of image processing.

In recent years, many products use an image processing processor, and a method of developing an image processing program by incorporating an image processing evaluation board equipped with the image processing processor used in the product into a personal computer has been adopted. If you install this program in the actual machine, you must add the program. In particular, it is necessary for the image processor to verify / debug even a signal called a gate signal that controls the handling of image data, and it has been difficult to construct the environment with conventional tools.

[0004]

Since the image processor carries out the image processing according to the gate signal for controlling the processing of the image data, it is necessary to evaluate the image processing including the input gate signal. Since it is a control signal used on an image processing device such as a copying machine, it is not handled as a debug target in a general-purpose image processing development device. Therefore, even if the image processing program can be developed on a personal computer, it is necessary to add or change the program to be installed in the actual machine. For this reason, defects were often found after the image processing program was installed in an actual machine.

Further, the gate signal is a signal supplied from an input device such as a scanner, and its pattern differs depending on the input device used, so that it is very difficult to reproduce all patterns on a personal computer. Similarly, in order to verify the output from the image processor, it is necessary to record all output images and output gate signals, and there is a problem that a large-scale device is required.

According to the present invention, a user can easily change the pattern of the gate signal by using the same image processor as that used in the actual machine, and the gate signal can be obtained without requiring large-scale equipment or equipment or special knowledge. It is an object of the present invention to provide an image processing evaluation system that enables verification and debugging of image processing including the processing of (1) and evaluation on an image after image processing and debugging at the assembler level of the image processing processor.

SUMMARY OF THE INVENTION The present invention has an input image port for inputting image data and a gate signal input terminal for inputting a gate signal composed of a plurality of signals for controlling the handling of the image port data. An image processing processor that captures image data according to the input gate signal, performs image processing, outputs the image data after the image processing from the output image port, and at the same time outputs a gate signal for controlling the handling of the data of the output image port. A program transfer means for loading and executing the image processing program on the image processor, and a data input for reading the input image and the input gate signal from the input data file storing the information of the input image and the input gate signal and inputting them to the image processor Means, output image and output gate signal output from the image processor Data output means for storing information in an output data file, input gate signal defining means for defining a pattern of an input gate signal input to the image processor to set an input timing of image data, and the set input gate signal Definition and input data file generating means for generating an input data file for reading the input image file and inputting it to the image processor, and a separation condition for defining a condition of a gate signal for separating the image data from the output data file. Verification of the image processing program including definition means and output image separation means for reading the definition of the set separation condition, separating the image from the output data file and outputting the image to the output image file It is characterized by performing.

According to the above arrangement, the user can easily change the pattern of the input gate signal, so that the image processing program corresponding to various input devices can be developed on the personal computer, and the handling of the gate signal is included. The operation of the image processing program and the output after the image processing can be verified.

By the way, in an image processing system typified by a digital copying machine, image processing is performed using a plurality of image processing processors. In order to reproduce the actual processing using a single image processor,
It is necessary to use the data after the image processing as the input data for the next image processing, but the output data has a different data length depending on the contents of the processing, and therefore the input control must be performed independently for each input data file. In this case, there is a problem that the system becomes complicated because the data input means is required for the number of input data and the timing management between the data input means is required. Therefore, according to the present invention, dummy data is added to a plurality of input data to be input to the data input means so that the data length corresponding to one image line is made uniform so that the output data having different data lengths is not complicated. It is an object of the present invention to provide an image processing evaluation device capable of inputting as the input data of the next image processing.

To achieve the above object, the present invention enables the data input means to be input to a plurality of input image ports, and provides a plurality of independent data output means for a plurality of output image ports of an image processor. , When a plurality of image processing programs are sequentially selected, transferred to the image processing processor and executed, and the output image data file which is the processing result of each image processing program is used as the input data file for the next image processing, It is characterized by comprising data length adjusting means for making it possible to align image data lengths of different data lengths input to the data inputting means by adding dummy data to the data of one line image of the input data file. .

According to the above configuration, even if the data lengths corresponding to one image line of the plurality of output data output after the image processing are different, a dummy is added to the input data to treat them as the same length data. Since the output image data can be used as the input image data for the next image processing, the image processing can be repeated without complicating the system. As a result, the image processing environment realized by using a plurality of image processing processors in the actual machine can be reproduced by the single image processing processor of the image processing evaluation device on the personal computer.

When an abnormal image is output as a result of the image processing, it is necessary to debug the image processing program using the image data of the part where the abnormality has occurred. Since the actual device uses an input device such as a scanner, input of image data cannot be stopped during debugging. On the other hand, when the program is forcibly stopped, image data overrun occurs, so that the image data after the program is stopped cannot be guaranteed.

Therefore, it is an object of the present invention to provide an image processing evaluation apparatus capable of debugging at the assembler level by using image data of a portion where an abnormality has occurred.

In order to achieve the above object, the present invention comprises data input means capable of controlling the amount of data read from the input data file and input to the image processor.
After transferring the image processing program to the image processing processor, specify the input data file and the output data file,
A control script executing means capable of reading a control script described so as to repeatedly input an input image for one line of an image in the main scanning direction and an input gate signal, and selecting continuous execution of a plurality of lines of the script or execution of each line. And an image processing processor debugging means capable of debugging an image processing program executed by the image processing processor at the assembler level, and image data is input line by line to debug the image processing at the assembler level. And

According to the above arrangement, the user can easily change the image processing program and the input image by changing the control script. In addition, since it is possible to temporarily stop the input image data, which is impossible on an actual machine, it is possible to debug at the assembler level using a specific part of the input image.

Further, in debugging the image processing program, the program of the image processing processor is often stopped by the debugger, and therefore it is necessary to stop the input of the input image data in order to prevent the loss of the input image due to overflow. In the image processing evaluation apparatus according to the third aspect, it is necessary to adjust the input image data amount by operating the control script executing means, which causes a problem that the operation becomes complicated.

Therefore, in the present invention, when the execution of the image processing program is stopped by the debugger, the image data input to the image processor is temporarily stopped, and when the execution is restarted from the debugger, the image data input is automatically restarted. It is an object of the present invention to provide an image processing device that does not require a complicated operation and prevents a loss of an input image to an image processor.

In order to achieve the above object, the present invention provides an input data stop means for controlling temporary stop of data input by the data input means, and whether or not an image processing program executed by an image processor is running. A program stop notifying means for monitoring whether or not it is in progress and requesting a temporary stop of data to the control script executing means and the data input stopping means if it is stopped, and requesting restart of data input if it is being executed It is characterized in that the data input is automatically stopped and restarted when the image processing program is executed and stopped by the image processor debug means.

According to the above configuration, even if the execution of the image processing program is stopped by the debugger, it is not necessary for the user to control the input amount of the input image data, and a debug device in which the input image data is not lost is realized. it can.

FIG. 2 is a block diagram showing the arrangement of an image processing evaluation apparatus according to the second embodiment of the present invention. Since the second embodiment also has the same basic configuration as the first embodiment, the description will focus on the points that differ from the first embodiment.

The image processing evaluation main body 21 includes an image processor 22, a plurality of input data files 25A and 25B.
Data input means 23 for reading the input image and the input gate signal from the image processing processor 22 and inputting them to the image processing processor 22; and data output means 24 for giving the output image and the output gate signal information output from the image processing processor 22 to the plurality of output data files , And a program transfer means 27 for reading the program stored in the image processing program 28A ...

The image processor 22 has a plurality of input ports and a plurality of output ports. Therefore, the data input means 23 can be input to a plurality of input image ports, and a plurality of independent data output means 24, 24 are provided for the plurality of output image ports of the image processor 22. Then, a plurality of image processing programs 28A, 28B, 28
The image processing control means 29 sequentially selects C and transfers it to the image processing processor 2 for execution. Output image data file 26 which is the processing result of each image processing program
A and 26B are input data files 25 for the next image processing.
When used as A and 25B, by adding dummy data to the data for one line of the image in the input data files 25A and 25B, it is possible to align image data lengths of different data lengths input to the data input means. The data length adjusting means 30 is provided.

Next, the second embodiment will be described based on its operation. The image processing control means 29 selects an image processing program A (28A) from a plurality of prepared image processing programs.
Is selected and transferred to the image processor 22 through the program transfer means 27. When the image processing program A is transferred, the image processing processor 22 executes the image processing program and waits for input data.

Next, the data input means 23 outputs image data corresponding to one image line from the input data files 1 and 2 (25A, 25B) created by the input data file generation means shown in the first embodiment. It is read and input to the image processing processor 22. This is repeated thereafter, and all the data in the input data files 1 and 2 (25A, 25B) are transferred to the image processor 22. In this case, the input data files 1 and 2 (25A, 25B) are generated by the input data file generation means with the same data length of the data corresponding to one line of the image, so the data length adjustment means 30 does not function.

On the other hand, the image processor 22 takes in the input data, performs the image processing, and outputs the output data. A plurality of output data are independent data output means 1, 2
According to (24), individual output data files 1, 2 (2
6A, 26B).

The image processing control means 29 receives the image processing program B when the processing of the image processing program A (28A) is completed.
(28B) is transferred to the image processing processor 22, and output data files 1 and 2 of the image processing program A (26A,
26B) as input data files 1 and 2 (25A, 25
Use as B) and repeat the above operation. At this time, when the data length corresponding to one image line of the output data files 1 and 2 (26A, 26B) is different, the data length adjusting means 30 sets dummy data to the data of one image line of the input data file. It is added, adjusted to the same length, and passed to the data input means 23.

In an image processing system represented by a digital copying machine, image processing is performed using a plurality of image processing processors. In order to reproduce the processing on the actual machine using a single image processing processor, it is necessary to use the data after image processing as input data for the next image processing, but the output data may be data depending on the processing content. Since the lengths are different, independent input control must be performed for each input data file. In this case, there is a problem that the system becomes complicated because the data input means is required for the number of input data and the timing management between the data input means is required. In this second embodiment,
The data length adjusting means 30 adds dummy data to a plurality of input data input to the data input means 23 to make the data length corresponding to one image line uniform. Therefore, output data having different data lengths can be input as input data for the next image processing without complicating the system configuration, and processing on an actual machine can be reproduced using a single image processing processor.

Next explained is the third embodiment of the invention. When an abnormal image is output as a result of the image processing, it is necessary to debug the image processing program using the image data of the part where the abnormality has occurred. Since the actual device uses an input device such as a scanner, input of image data cannot be stopped during debugging. Further, when the program is forcibly stopped, image data overrun occurs, so that the image data after the program is stopped cannot be guaranteed. The third embodiment enables debugging at the assembler level by using image data of a part where an abnormality has occurred.

FIG. 3 is a block diagram showing the arrangement of an image processing evaluation apparatus according to the third embodiment of the present invention. Since the third embodiment also has the same basic configuration as the first embodiment, the description will focus on the points different from the first embodiment. FIG. 5 is an example of a control script according to the third embodiment.

Next, when the operator stops the execution of the image processing program of the image processor 32 by the image processor debug means 41 and executes the eighth line up to the 8th line by the control script execution means 37, the image data of the 3001th line is input. The image is input to the image processor 32 through the means 33, and the image processor 32 stores the input image in the internal FIFO memory regardless of whether the program is executed or stopped.

The image processing processor 32 does not perform image processing immediately because the program is stopped, but when the operator executes the program of the image processing processor 32 by the image processing processor debug means 41 in units of instructions, the image data in the FIFO memory is saved. Image data is sequentially taken into an internal register and image processing is performed. By verifying the process of image processing through the image processing processor debug means 41, the operator can debug with the data of the target line.

FIG. 7 shows the operation flow of the operator and the operation flow of the control script executing means and the image processor in the third embodiment. The arrows in FIG. 7 indicate the relationship of action. The operation will be described with reference to FIG.

As shown in FIG. 7, the operator executes the control script executing means 37 up to the sixth line of the control script of FIG. 5, and gives an instruction to stop at the seventh line (S1).
The control script control means 37 gives an instruction to download the image processing program 40 in the first line of the control script (S2). In the image processor 32, the program is downloaded by the program transfer means 39. When the image processing processor 32 finishes the download, the image processing processor 32 starts executing the image processing professional program, and waits for the input of the input image and the input gate signal (S5).

The control script executing means 37 executes from the second line to the sixth line, specifies the input image file and the output image file (S4), and processes the images up to the 3000th line of the image and the input gate signal. It is given to the processor 32 (S6). Then, the operation is stopped (S8).

The image processor 32 sequentially processes the input images and processes 3000 lines (S7). Then, the input image and the input gate signal are awaited again.

Next, when the operator sets the execution stop of the image processing program of the image processing processor 32 by the image processing processor debugging means 41 (S9), the image processing processor 32 is stopped (S10).

When the operator instructs execution up to the 8th line of the control script line by line (S11), the control script executing means 37 executes 30 up to the 8th line in line units.
The image data of the 01st line is input to the image processor 32 through the data input means 33 (S12). The image processor 32 stores the input image in the internal FIFO memory regardless of whether the program is executed or stopped (S1).

The image data in the memory is sequentially loaded into the internal register and image processing is performed (S15).

When the operator restarts the execution of the program by the image processor debug means 41 (S1

Next, a fourth embodiment will be described. In debugging the image processing program according to the present invention, the program of the image processing processor is often stopped by the debugger. Therefore, it is necessary to stop the input of the input image data in order to prevent the loss of the input image due to overflow. In the image processing evaluation apparatus of the third embodiment, it is necessary to adjust the input image data amount by operating the control script executing means, which causes a problem that the operation becomes complicated.

Therefore, in the fourth embodiment, when the execution of the image processing program is stopped by the debugger, the image data input to the image processing processor is temporarily stopped, and when the execution is restarted from the debugger, the image data input is automatically restarted. By doing so, a complicated operation is not required and a loss of an input image to the image processing processor is prevented.

FIG. 4 is a block diagram showing the arrangement of an image processing evaluation apparatus according to the fourth embodiment of the present invention. Since the fourth embodiment also has the same basic configuration as the first embodiment, the description will focus on the points different from the first embodiment. The fourth embodiment will also be described assuming that the control script of FIG. 5 is used.

If the program is in the middle, the control script executing means 60 and the data input stopping means 62 are requested to suspend the data, and if it is in the running state, the program stop notifying means 63 is requested to restart the data input.

With this configuration, the data input is automatically stopped and restarted in accordance with the execution and stop of the image processing program by the image processor debug means 59.

Next, the operation of the fourth embodiment will be described. When the operator instructs the control script executing means 50 to execute the control script (51), the following operation is performed according to the control script shown in FIG.

The first line of the control script causes the image processing program 58 to be downloaded to the image processing processor 52 through the program transfer means 57. When the download is completed, the image processor 52 starts executing the image processing program, and waits for the input image and the input gate signal.

Next, the second and third lines of the control script specify the input from the input data file 55 and the output to the output data file 56. Control script 4
When the row and subsequent rows are executed, the input image and the input gate signal are sequentially input to the image processing processor 52, and the image processing processor 52 performs image processing on the input image input.

The image processor debug means 59 has the function of controlling the execution stop of the program of the image processor 52 and the breakpoint can be set so as to stop the program when the program counter matches a specific address. Further, the image processor debug means 59 has a function of referring to the FIFO memory, the register and the memory inside the image processor while the program is stopped.

When the breakpoint set by the operator is reached or when the operator forcibly instructs the program to stop, the image processor 52 stops the execution of the program. Program stop notification means 63
Monitors the stop of the program of the image processing processor, and when detecting the stop of the program, notifies the input data stop means 62 of the stop of the program and at the same time causes the control script executing means 60 to stop the execution of the control script. The input data stop means 62 suspends the image data input by the data input means 53 in response to a request from the program stop notification means 63.

As described above, in the fourth embodiment, the image data input to the image processing processor 52) is stopped at the same time when the program of the image processing processor 52 is stopped, thereby preventing the loss of the input image due to the overflow. .
